Histoplasmosis oral como diagnóstico diferencial de cáncer oral. Serie de casos y revisión de la literatura / Oral histoplasmosis as a differential diagnosis of oral cancer. Case series and literature review

Objetivo: La histoplasmosis es una infección fúngica sistémica prevalente en la región del Río de la Plata. Puede exhibir manifestaciones orales, cutáneas y/o sistémicas. Las lesiones bucales significan un desafío diagnóstico debido a su semejanza clínica con el carcinoma oral de células escamosas (COCE). El objetivo de este trabajo fue presentar una serie de casos de histoplasmosis oral enfatizando la importancia del diagnóstico diferencial clínico con el COCE. Casos clínicos: Se describen casos de histoplasmosis oral diagnosticados en los últimos 5 años en la Cátedra de Estomatología "A" de la Facultad de Odontología de la Universidad Nacional de Córdoba, Córdoba, Argentina. En forma paralela, se realizó una revisión de la literatura de los últimos 10 años. Los casos corresponden a 9 pacientes, 6 varones y 3 mujeres, cuya edad promedio fue de 58,6 años. 4 pacientes eran VIH positivos. Se planteó la sospecha de COCE en 5 pacientes, cuya presentación clínica intraoral consistía en úlceras o lesiones ulcerovegetantes, mayormente únicas, ubicadas en la encía. La revisión bibliográfica arrojó un resultado de 48 artículos que incluyeron 60 casos de histoplasmosis oral, con una prevalencia mayor en hombres y similitudes clínicas con COCE en el 80% de los casos. La lesión más predominante fue la úlcera en el 85% de los casos, ubicada en lengua, seguido por el paladar. El diagnóstico de histoplasmosis oral es desafiante y requiere un amplio diferencial, ya que se asemeja a múltiples patologías, debiendo ser considerada ante lesiones ulcerativas orales. Un diagnóstico preciso, de manera interdisciplinaria, es esencial para un tratamiento efectivo.(AU)

Aim: Histoplasmosis is a systemic fungal infection prevalent in the Río de la Plata region. It could present oral, cutaneous and/or systemic manifestations. Oral lesions represent a diagnostic challenge due to their clinical similarity to oral squamous cell carcinoma (OSCC). The objective of this work is to present a case series of oral histoplasmosis emphasizing the importance of clinical differential diagnosis with OSCC. Clinical cases: Cases of oral histoplasmosis diagnosed in the last 5 years in the Oral Medicine Department "A" of the Facultad de Odontología of the Universidad Nacional de Córdoba, Córdoba, Argentina are discribed. Alongside, a literature review of the last 10 years was carried out. 9 patients are described, 6 men and 3 women, whose average age was 58.6 years. 4 patients were HIV positive. The suspicion of OSCC was raised in 5 patients, whose intraoral clinical presentation consisted of single ulcers or vegetating ulcers, mostly single, located in the gingiva. The literature review included a total of 48 articles with 60 cases of oral histoplasmosis, with a higher prevalence in men and clinical similarities with OSCC in 80% of cases. The most predominant lesion was the ulcer in 85% of the cases, mostly located on the tongue, followed by the palate. The diagnosis of oral histoplasmosis is challenging and requires a wide differential, since it can mimic multiple pathologies, and should be considered in oral ulcerative lesions. An accurate diagnosis, in an interdisciplinary framework, is essential for effective treatment.(AU)

Comparison of Anatomically of Medial Plantar Flap versus Reverse Sural Fasciocutaneous Flap in the Treatment of Skin Defects After Cutaneous Squamous Cell Carcinoma Excision

SUMMARY: To compare the advantages and disadvantages of reverse sural fasciocutaneous flap (RSFF) versus medial plantar flap (MPF) in the treatment of skin defects after excision of squamous cell carcinoma (SCC) of the heel. The research participants were 80 SCC patients admitted to Lishui People's Hospital between January 2019 and April 2022, who were assigned to RSFF group (n=37) and MPF group (n=43) according to the flap type. After a one-year follow-up, the survival, flap necrosis and ulceration, as well as pain and tactile sensation recovery of both groups were counted. At the last follow-up, the clinical response was evaluated, and Short-Form 36 Item Health Survey (SF-36) and appearance satisfaction surveys were conducted. No patients died in either group, and one patient in each group developed flap necrosis. The MPF group had better sensory recovery and a lower incidence of flap ulceration (P0.05). The cosmetic satisfaction was higher in MPF group than in RSFF group (P<0.05). MPF contributes to beautiful appearance, better sensory recovery, and low risk of long-term ulceration, while RSFF is suitable for lesions with large defects or those located at the lateral heel.

El objetivo del estudio fue comparar las ventajas y desventajas del colgajo fasciocutáneo sural inverso (RSFF) versus el colgajo plantar medial (MPF) en el tratamiento de defectos de la piel después de la escisión de un carcinoma de células escamosas (CCE) del talón. Los participantes de la investigación fueron 80 pacientes con CCE ingresados en el Hospital Popular de Lishui entre enero de 2019 y abril de 2022, que fueron asignados al grupo RSFF (n=37) y al grupo MPF (n=43) según el tipo de colgajo. Después de un año de seguimiento, se observó la supervivencia, la necrosis y ulceración del colgajo, así como la recuperación del dolor y la sensación táctil de ambos grupos. En el último seguimiento, se evaluó la respuesta clínica y se realizaron encuestas de salud de formato corto de 36 ítems (SF-36) y encuestas de satisfacción. Ningún paciente falleció en ninguno de los grupos y un paciente de cada grupo desarrolló necrosis del colgajo. El grupo MPF tuvo una mejor recuperación sensorial y una menor incidencia de ulceración del colgajo (P 0,05). La satisfacción cosmética fue mayor en el grupo MPF que en el grupo RSFF (P<0,05). MPF contribuye a una mejor apariencia, mejor recuperación sensorial y un bajo riesgo de ulceración a largo plazo, mientras que RSFF es adecuado para lesiones con defectos grandes o localizados en la parte lateral del talón.

Overexpression SPRY2 Suppresses Esophageal Squamous Cell Carcinoma Progression Via Inactivation of ERK/AKT Signaling / La Sobreexpresión SPRY2 Suprime la Evolución del Carcinoma de Células Escamosas de Esófago Mediante la Inactivación de la Señalización ERK/AKT

SUMMARY: Esophageal cancer is one of the most aggressive gastrointestinal cancers. Invasion and metastasis are the main causes of poor prognosis of esophageal cancer. SPRY2 has been reported to exert promoting effects in human cancers, which controls signal pathways including PI3K/AKT and MAPKs. However, the expression of SPRY2 in esophageal squamous cell carcinoma (ESCC) and its underlying mechanism remain unclear. In the present study, we aimed to investigate the detailed role of SPRY2 in the regulation of cell proliferation, invasion and ERK/AKT signaling pathway in ESCC. It was identified that the expression level of SPRY2 in ESCC was remarkably decreased compared with normal tissues, and it was related to clinicopathologic features and prognosis ESCC patients. The upregulation of SPRY2 expression notably inhibited the proliferation, migration and invasion of Eca-109 cells. In addition, the activity of ERK /AKT signaling was also suppressed by the SPRY2 upregulation in Eca-109 cells. Our study suggests that overexpression of SPRY2 suppress cancer cell proliferation and invasion of by through suppression of the ERK/AKT signaling pathways in ESCC. Therefore, SPRY2 may be a promising prognostic marker and therapeutic target for ESCC.

El cáncer de esófago es uno de los cánceres gastrointestinales más agresivos. La invasión y la metástasis son las principales causas de mal pronóstico del cáncer de esófago. Se ha informado que SPRY2 ejerce efectos promotores en los cánceres humanos, que controla las vías de señales, incluidas PI3K/AKT y MAPK. Sin embargo, la expresión de SPRY2 en el carcinoma de células escamosas de esófago (ESCC) y su mecanismo subyacente aún no están claros. En el presente estudio, nuestro objetivo fue investigar el papel detallado de SPRY2 en la regulación de la proliferación celular, la invasión y la vía de señalización ERK/AKT en ESCC. Se identificó que el nivel de expresión de SPRY2 en ESCC estaba notablemente disminuido en comparación con los tejidos normales, y estaba relacionado con las características clínico-patológicas y el pronóstico de los pacientes con ESCC. La regulación positiva de la expresión de SPRY2 inhibió notablemente la proliferación, migración e invasión de células Eca-109. Además, la actividad de la señalización de ERK/AKT también fue suprimida por la regulación positiva de SPRY2 en las células Eca-109. Nuestro estudio sugiere que la sobreexpresión de SPRY2 suprime la proliferación y la invasión de células cancerosas mediante la supresión de las vías de señalización ERK/AKT en ESCC. Por lo tanto, SPRY2 puede ser un marcador de pronóstico prometedor y un objetivo terapéutico para la ESCC.

Carcinoma oral de células escamosas en el paladar: reporte de un caso / Oral squamous cell carcinoma of the palate: a case report

El cáncer oral representa un grave problema de salud a nivel mundial debido a su importante morbilidad y mortalidad. Ocupa la sexta causa de muerte por cáncer y tienen una supervivencia mundial a cinco años cercana a 50%, en gran parte debido a la falta de su reconocimiento en estadios iniciales por parte de los pacientes y de los mismos profesionales de la salud, lo que ocasiona un grave retraso en su diagnóstico y tratamiento. Se presenta el caso de una mujer de 64 años de edad con úlceras de larga evolución en la cavidad oral y quien acude a múltiples profesionales de salud sin ser diagnosticada en las fases iniciales de la enfermedad; acude a la Universidad Autónoma de Tlaxcala en donde se diagnostica carcinoma oral de células escamosas en el maxilar. En el presente artículo se hace énfasis en el reconocimiento de signos clínicos y factores precipitantes que puedan generar sospecha de un crecimiento maligno y así concientizar a los profesionales de la salud para promover la prevención (AU)

Oral cancer represents a serious health problem worldwide due to its significant morbidity and mortality, it is the sixth leading cause of cancer death and has a global 5-year survival rate of 50%, largely due to the lack of recognition in early stages by patients and health professionals themselves, which causes a serious delay in diagnosis and treatment. We present the case of a 64-year-old woman with long-standing ulcers in the oral cavity who went to multiple health professionals without being diagnosed in the initial stages of the disease. She went to the Autonomous University of Tlaxcala where oral squamous cell carcinoma (OSCC) in the maxilla was diagnosed. This article emphasizes the recognition of clinical signs and precipitating factors that may generate suspicion of malignant growth and thus raise awareness among health professionals to promote prevention (AU)

Carcinoma de células escamosas de lábio inferior: Excisão e reconstrução com retalho nasolabial / Squamous cell carcinoma of the lower lip: Excision and reconstruction with nasolabial flap

Introdução: O carcinoma de células escamosas é o tumor maligno mais frequente dos lábios e acomete principalmente o lábio inferior. O tratamento adequado desta neoplasia deve ser precoce e radical, pois metástases podem ocorrer. Considerando que os lábios têm extrema relevância na dinâmica e motricidade da face, a reconstrução labial após grandes ressecções nesta região é um desafio para o cirurgião na busca de bons resultados estéticos e funcionais. Este estudo busca apresentar uma técnica já consagrada e confiável para a reconstrução do lábio inferior após ressecções tumorais, o retalho de Karapandizic. Método: Nesta revisão de casos são avaliados, retrospectivamente, 4 pacientes que tiveram o lábio inferior reconstruído por meio da técnica de Karapandzic no período de 2013-2022. Resultados: As complicações mais frequentemente observadas foram cicatriz hipertrófica, deiscência de sutura em vermelhão de lábio e microstomia (redução da abertura oral). A redução da fenda labial (microstomia) foi corrigida parcialmente através do uso de órteses odontológicas, não havendo necessidade de indicação de comissuroplastia em nenhum dos casos. Outra colaboração deste trabalho refere-se à utilização do ecoDoppler colorido pré-operatório, que permite o planejamento do retalho verificando a viabilidade do pedículo vascular e o real posicionamento deste pedículo, reduzindo as chances de lesão inadvertida dos vasos durante a cirurgia. Conclusão: Mesmo sendo a microstomia uma limitação deste retalho, concluímos que esta técnica atende à necessidade de reconstrução de lábio inferior em grandes ressecções, uma vez que é capaz de proporcionar resultados satisfatórios em termos oncológicos, funcionais e estéticos.

Introduction: Squamous cell carcinoma is the most common malignant tumor of the lips and mainly affects the lower lip. Adequate treatment of this neoplasm must be early and radical, as metastases can occur. Considering that the lips are extremely important in the dynamics and motricity of the face, lip reconstruction after major resections in this region is a challenge for the surgeon in the search for good aesthetic and functional results. This study seeks to present an already established and reliable technique for reconstructing the lower lip after tumor resection, the Karapandizic flap. Method: In this case review, 4 patients with lower lips reconstructed using the Karapandzic technique in 2013-2022 are retrospectively evaluated. Results: The most frequently observed complications were hypertrophic scar, lip vermilion suture dehiscence, and microstomia (reduction of oral opening). The cleft lip (microstomia) reduction was partially corrected through dental orthoses, with no need for commissuroplasty in any of the cases. Another contribution of this work is the use of preoperative color echoDoppler, which allows flap planning by checking the viability of the vascular pedicle and the actual positioning of this pedicle, reducing the chances of inadvertent injury to the vessels during surgery. Conclusion: Even though microstomy is a limitation of this flap, we conclude that this technique meets the need for lower lip reconstruction in large resections, as it can provide satisfactory results in oncological, functional, and aesthetic terms.

Effect of Survivin Down-Regulation by Egr1-Survivin shRNA Combined with Radiotherapy on Radiosensitivity of Esophageal Squamous Carcinoma / Efecto de la Regulación Negativa de Survivina por shRNA de Egr1-Survivina Combinado con Radioterapia sobre la Radiosensibilidad del Carcinoma Escamoso de Esófago

SUMMARY: This study is to investigate the effect of survivin down-regulation by Egr1-survivin shRNA combined with radiotherapy on the apoptosis and radiosensitivity of esophageal squamous cell carcinoma ECA109 and KYSE150 cells. ECA109 and KYSE150 cells were transfected with Egr1-survivin shRNA, and then treated with radiotherapy. After 24 h, the mRNA and protein levels of Egr1-survivin were detected by qPCR and Western-Blot. Cell cycle and apoptosis were detected by flow cytometry. Western blot also detected levels of cleavaged Caspase 3 and Caspase 9. YM155 was used as a positive control to inhibit survivin expression. The levels of survivin mRNA and protein in ECA109 and KYSE150 cells treated with Egr1-survivin shRNA combined with radiotherapy were significantly lower than those of the blank control group, the empty vector control group, and, the YM155 + radiotherapy group (P<0.05). Meanwhile, after survivin down-regulation, the ratio of G2 to S phase of ECA109 and KYSE150 cells increased significantly, leading to significant G2 and S phase arrest. Additionally, apoptosis of ECA109 and KYSE150 cells increased significantly (P <0.01). Further, protein levels of cleavaged Caspase 3 and Caspase 9 significantly increased in Egr1-survivin shRNA combined with radiotherapy group. Egr1-survivin shRNA combined with radiotherapy can down-regulate survivin expression, which further increases the apoptosis, and enhances the radiosensitivity of ECA109 and KYSE150 cells.

Este estudio tuvo como objetivo investigar el efecto de la regulación negativa de survivina por el shRNA de Egr1-survivina combinado con radioterapia sobre la apoptosis y la radiosensibilidad del carcinoma de células escamosas de esófago Células ECA109 y KYSE150. Las células ECA109 y KYSE150 se transfectaron con shRNA de survivina Egr1 y luego se trataron con radioterapia. Después de 24 h, los niveles de ARNm y proteína de Egr1-survivina se detectaron mediante qPCR y Western-Blot. El ciclo celular y la apoptosis se detectaron mediante citometría de flujo. La transferencia Western también detectó niveles de Caspasa 3 y Caspasa 9 escindidas. Se usó YM155 como control positivo para inhibir la expresión de survivina. Los niveles de ARNm y proteína de survivina en células ECA109 y KYSE150 tratadas con shRNA de survivina Egr1 combinado con radioterapia fueron significativamente más bajos que los del grupo control en blanco, el grupo control de vector vacío y el grupo de radioterapia YM155 + (P <0,05). Mientras tanto, después de la regulación negativa de survivina, la proporción entre las fases G2 y S de las células ECA109 y KYSE150 aumentó significativamente, lo que llevó a una detención significativa de las fases G2 y S. Además, la apoptosis de las células ECA109 y KYSE150 aumentó significativamente (P <0,01). Además, los niveles de proteína de Caspasa 3 y Caspasa 9 escindidas aumentaron significativamente en el shRNA de Egr1- survivina combinado con el grupo de radioterapia. El shRNA de survivina de Egr1 combinado con radioterapia puede regular negativamente la expresión de survivina, lo que aumenta aún más la apoptosis y mejora la radiosensibilidad de las células ECA109 y KYSE150.

Queilite actínica ("Lábios de Marinheiro"): uma Revisão para o Clínico / Actinic cheilitis ("sailor's lips"): A review for the clinician

A Queilite Actínica (QA), também conhecida como "lábios de marinheiro", é uma patologia com potencial de malignização e, ainda que seja de fácil diagnóstico e prevenção, casos diagnosticados tardiamente podem evoluir para carcinoma de lábios. Seu principal fator etiológico é a exposição aos raios ultravioletas, e por este motivo, indivíduos que se expõem muito ao sol, incluindo militares, podem ser considerados grupo de risco para a doença. O objetivo principal deste trabalho foi descrever os principais fatores de risco e prognósticos da QA e apresentar uma revisão para o cirurgião-dentista, facilitando a identificação e conduta. Para tal, foi realizada busca de artigos pertinentes ao tema nas bases de dados Medline, Lilacs, SciELO e PubMed, de 1987 a 2022. O seguinte perfil do paciente com QA foi identificado: homem, na quinta década de vida, pele clara, com lesões no lábio inferior e com histórico de longo tempo de atividades ocupacionais ao ar livre/intensa exposição solar. O cirurgião-dentista possui papel fundamental na identificação dos grupos de risco, no reconhecimento precoce da doença e, em casos mais avançados, realizar o diagnóstico e o correto encaminhamento para atendimento especializado.

Actinic Cheilitis (AC), also known as "sailor's lips", is a premalignant pathology, and although it is easy to diagnose and prevent, late diagnosed cases may progress to lip carcinoma. Since its main etiological factor is exposure to ultraviolet rays, individuals often exposed to the sun, including military personnel, can be considered a risk group for the disease. The aim of this study was to describe the main risk and prognostic factors of AC and to create a clinical protocol for dental surgeons, making easier to identify and conduct each case. For this purpose, a search for articles relevant to the topic was carried out in Medline, Lilacs, SciELO and PubMed databases, from 1987 to 2022. The following AC patient profile was identified: male, in the fifth decade of life, fair skinned, with lesions on the lower lip and with a long history of outdoor occupational activities/intense sun exposure. The dentist has a fundamental role in identifying risk groups, early recognition of the disease and in more advanced cases, making the correct diagnosis and recommendation to specialized care.

Survival of patients living with HIV and cancer in Cali, Colombia

Background: People living with HIV have an increased risk of cancer compared to the general population. However, with the increase in life expectancy and advances in antiretroviral therapy, the survival of patients with cancer and HIV has changed. Objective: To determine the survival of patients living with HIV and cancer in Cali, Colombia Methods: A retrospective cohort study was conducted at the Fundación Valle del Lili, Cali, Colombia. Data from the HIV database was crossed with data from the hospital and population-based cancer registries between 2011-2019. Patients <18 years, limited available clinical information on the diagnosis and treatment of HIV and cancer, and non-oncological tumor diagnosis were excluded. Results: A total of 173 patients were included. The frequencies of AIDS-defining neoplasms were: Non-Hodgkin lymphoma (42.8%), Kaposi sarcoma (27.8%), and cervical cancer (4.6%). Overall survival was 76.4% (95% CI 68.9-82.3) at five years. Poorer survival was found in patients with AIDS-defining infections (56.9% vs. 77.8%, p=0.027) and non-AIDS-defining infections (57.8% vs. 84.2%, p=0.013), while there was better survival in patients who received antiretroviral therapy (65.9% vs. 17.9%, p=0.021) and oncological treatment (66.7% vs. 35.4%, p<0.001). The presence of non-AIDS-defining infections increases the risk of dying (HR = 2.39, 95% CI 1.05-5.46, p=0.038), while oncological treatment decreases it (HR = 0.33, 95% CI 0.14-0.80, p=0.014). Conclusions: In people living with HIV, Non-Hodgkin lymphoma and Kaposi sarcoma are the most common neoplasms. Factors such as AIDS-associated and non-AIDS-associated infections have been identified as determinants of survival. Cancer treatment seems to improve survival.

Antecedentes: Las personas que viven con VIH tienen un riesgo mayor de cáncer en comparación con la población general. Sin embargo, con el aumento de la esperanza de vida y los avances en la terapia antirretroviral, la supervivencia de los pacientes con cáncer y VIH ha cambiado. Objetivo: Determinar la supervivencia de los pacientes que viven con VIH y cáncer en Cali, Colombia. Métodos: Se realizó un estudio de cohorte retrospectivo en la Fundación Valle del Lili, Cali, Colombia. Los datos de la base de datos de VIH se cruzaron con los datos de los registros de cáncer de base hospitalaria y poblacional entre 2011-2019. Se excluyeron los pacientes <18 años, con información clínica limitada disponible sobre el diagnóstico y tratamiento del VIH y el cáncer y los casos con diagnóstico de tumor no oncológico. Resultados: Se incluyeron un total de 173 pacientes. Las frecuencias de neoplasias definitorias de SIDA fueron: linfoma no Hodgkin (42.8%), sarcoma de Kaposi (27.8%) y cáncer cervical (4.6%). La supervivencia global fue del 76.4% (IC 95% 68.9-82.3) a los cinco años. Se encontró una peor supervivencia en pacientes con infecciones definitorias de SIDA (56.9% vs. 77.8%, p=0.027) e infecciones no definitorias de SIDA (57.8% vs. 84.2%, p=0.013), mientras que hubo una mejor supervivencia en pacientes que recibieron terapia antirretroviral (65.9% vs. 17.9%, p=0.021) y tratamiento oncológico (66.7% vs. 35.4%, p<0.001). La presencia de infecciones no definitorias de SIDA aumentó el riesgo de morir (HR = 2.39, IC 95% 1.05-5.46, p=0.038), mientras que el tratamiento oncológico lo disminuyó (HR = 0.33, IC 95% 0.14-0.80, p=0.014). Conclusiones: En las personas que viven con VIH, el linfoma no Hodgkin y el sarcoma de Kaposi son las neoplasias más comunes. Se han identificado factores como las infecciones asociadas al SIDA y las infecciones no asociadas al SIDA como determinantes de la supervivencia. El tratamiento del cáncer parece mejorar la supervivencia.

Marjolin ulcer: the importance of early diagnosis and excision / Úlcera de Marjolin: a importância do diagnóstico e excisão precoces

Introduction: Marjolin's ulcer is a rare disease characterized by the malignancy of chronic wounds that present healing disorders, often due to chronic irritation and repetitive trauma in this area. The diagnosis is made mainly through clinical history and histopathological examination. The differential diagnoses of other diseases that course with ulcers must always be researched and ruled out. Method: The present work presents a bibliographic review to elucidate the subject's relevance for medical students, physicians and nurses, to assist in early diagnosis. Results: Nine observational studies were selected to compose the discussion. Conclusion: The most effective treatment for this condition is surgery, and lymph node dissection is suggested in some cases. Chemotherapy has not shown satisfactory results, while radiotherapy is used in selected cases. Given the rapid evolution, tissue damage, and worse prognosis, diagnosis, and excision should be performed early for a better clinical outcome.

Introdução: A úlcera de Marjolin é uma doença rara, caracterizada pela malignização de feridas crônicas que apresentaram distúrbios cicatriciais, muitas vezes devido à irritação crônica e a traumas repetitivos nesta área. O diagnóstico é realizado sobretudo através da história clínica e de exame histopatológico. Os diagnósticos diferenciais de outras doenças que cursam com úlceras devem sempre ser pesquisados e afastados. Método: O presente trabalho apresenta uma revisão bibliográfica, a fim de elucidar a relevância do tema para acadêmicos de medicina, médicos e enfermeiros, com o propósito de auxiliar no diagnóstico precoce. Resultados: Foram selecionados 9 estudos observacionais para compor a discussão. Conclusão: O tratamento mais eficaz desta condição é o cirúrgico, e o esvaziamento linfonodal é sugerido em alguns casos. A quimioterapia não demonstrou resultados satisfatórios, enquanto a radioterapia é utilizada em casos selecionados. O diagnóstico e a excisão devem ser feitos precocemente para melhor desfecho clínico, visto a rapidez da evolução, o prejuízo tecidual e pior prognóstico.

Non-melanoma skin cancer: an analysis of compromised margins in excisions / Câncer de pele não melanoma: uma análise do comprometimento de margens em excisões

Introduction: Non-melanoma skin cancer is the most frequent neoplasm in Brazil, with an estimated 176,930 new cases during the 2020-2022 period, with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) as the most common subtypes. Surgical treatment of the lesions is effective, with a recurrence rate varying between 3 and 23%, with compromised margins being an important prognostic factor for this recurrence, increasing the importance of complete excision of the tumor. Method: To prepare this work, 1127 lesions treated at the Hospital de Amor Amazônia were analyzed, seeking to quantify cases and analyze surgically compromised margins through a retrospective analytical descriptive study. For this, histopathological reports of the operated patients were reviewed, dividing them according to sex, age, lesion topography, date of excision, lesion diameter, lesion depth, presence of ulceration, compromised margins, and histological type. Results: Among the lesions treated, 65% were BCC and 35% SCC, both histological types presenting a low incidence of compromised margins. In cases of CPB impairment, treatment via exeresis was chosen in 100% of cases. Concerning BCC impairment, the majority opted for clinical follow-up, with reapproach in only 9% of cases. Conclusion: This study demonstrates that the cases treated at the Hospital de Amor Amazônia align with the epidemiological data in the main literature, except for finding a higher incidence of non-melanoma skin cancer in men. In addition, this work demonstrates good results in the clinical approach of compromised margins in BCC lesions.

Introdução: O câncer de pele não melanoma é a neoplasia mais frequente no Brasil, com uma estimativa de 176.930 novos casos durante o triênio 2020-2022, tendo o carcinoma basocelular (CBC) e o carcinoma espinocelular (CEC) como subtipos mais presentes. O tratamento cirúrgico das lesões é efetivo, apresentando taxa de recorrência variando entre 3 e 23%, sendo o comprometimento de margens importante fator prognóstico para essa recorrência, aumentando a importância da excisão completa do tumor. Método: Para a elaboração deste trabalho, foram analisadas 1127 lesões abordadas no Hospital de Amor Amazônia, buscando quantificar casos e analisar margens cirurgicamente comprometidas por meio de um estudo descritivo analítico retrospectivo. Para isso, foram revisados laudos histopatológicos dos pacientes operados, dividindo-os de acordo com sexo, idade, topografia da lesão, data de excisão, diâmetro da lesão, profundidade da lesão, presença de ulceração, comprometimento de margens e tipo histológico. Resultados: Dentre as lesões abordadas, 65% eram CBC e 35% CEC, ambos os tipos histológicos apresentando baixa incidência de margens comprometidas. Nos casos de comprometimento em CEC, optou-se pelo tratamento via exérese em 100% dos casos. Já em relação ao comprometimento em CBC, optou-se majoritariamente pelo acompanhamento clínico, com reabordagem em apenas 9% dos casos. Conclusão: Este estudo demonstra que os casos abordados no Hospital de Amor Amazônia vão ao encontro dos dados epidemiológicos presentes nas principais literaturas, com ressalva, apenas, ao encontrar uma maior incidência de câncer de pele não melanoma em homens. Além disso, esse trabalho demonstra bons resultados na abordagem clínica de margens comprometidas em lesões de CBC.

Fatores associados ao atraso no diagnóstico e tratamento do câncer bucal: revisão integrativa de literatura / Factors associated with delay in the diagnosis of bucal cancer: integrative literature review

Introdução: O câncer bucal é apontado como um problema de saúde relevante e apresenta alta taxa de incidência e mortalidade. O consumo de tabaco e álcool são considerados os principais fatores de risco para sua ocorrência. Apesar dos avanços relacionados a detecção, diagnóstico e tratamento, grande parte dos pacientes ainda é diagnosticada com a doença em estágio avançado. Objetivo: Estabelecer os principais fatores associados ao atraso no diagnóstico do câncer bucal. Material e Métodos: Foram pesquisados artigos nas bases de dados MEDLINE/PubMed, SciELO e Lilacs, com os descritores: delayed oral cancer; delayed diagnosis oral cancer; oral cancer young patients; e HPV oral cancer patients. Como critérios de inclusão, foram delimitados artigos completos e disponíveis integramente. Publicações não relacionadas a delimitação do tema e ao objetivo do estudo foram excluídas. Resultados: Foram encontrados 513 artigos, dos quais 118 foram lidos na íntegra e 96 por fim selecionados, conforme critérios de inclusão e exclusão. Os dados indicaram que o atraso no diagnóstico do câncer bucal é frequente e relacionado ao atraso pelo paciente, atraso pelo profissional de saúde e atraso no tratamento, com destaque ao atraso pelo paciente. Conclusão: O diagnóstico precoce é o meio mais eficaz de reduzir as taxas de mortalidade e melhorar o prognóstico e qualidade de vida de pacientes com câncer bucal. Dessa forma, estratégias que objetivam a redução de diagnósticos realizados tardiamente devem ser consideradas.

Introduction: Oral cancer is identified as a relevant health problem and has a high incidence and mortality rate. Tobacco and alcohol consumption are considered the main risk factors for its occurrence. Despite advances related to detection, diagnosis and treatment, a large proportion of patients are still diagnosed with the disease at an advanced stage. Objective: To establish the main factors associated with delays in the diagnosis of oral cancer. Material and Methods: Articles were searched in the MEDLINE/PubMed, SciELO and Lilacs databases, with the descriptors: delayed oral cancer; delayed diagnosis of oral cancer; oral cancer young patients; and oral HPV cancer patients. As inclusion criteria, complete and fully available articles were delimited. Publications not related to the delimitation of the topic and the objective of the study were excluded. Results: 513 articles were found, of which 118 were read in full and 96 were finally selected, according to inclusion and exclusion criteria. The data indicated that delays in diagnosing oral cancer are frequent and related to delays by the patient, delays by healthcare professionals and delays in treatment, with emphasis on delays by the patient. Conclusion: Early diagnosis is the most effective way to reduce mortality rates and improve the prognosis and quality of life of patients with oral cancer. Therefore, strategies that aim to reduce late diagnoses should be considered.

Immunohistochemistry in oral and maxillofacial pathology: The role and rational use of antibodies in the diagnosis of surgical lesions / Inmunohistoquímica en patología oral y maxilofacial: El rol y uso racional de anticuerpos en el diagnóstico de lesiones quirúrgicas

Background:Immunohistochemistry have had a huge impact on oral and maxillofacial pathology diagnosis. As a method it determines distribution and amount of certain cellular molecules via specific antigen-antibody reaction. Whereas in most cases a definitive diagnosis is achieved based on detailed hematoxylin and eosin cytomorphological analysis, along with clinical and radiological features, some challenging and equivocal neoplasms need to be further assessed with immunohistochemistry. Objective:This article reviews and updates immunohistochemistry technique fundamentals, its role and relevance in the diagnosis of common oral and maxillofacial lesions encountered in daily practice. Materials and methods: A literature review on the topic was carried out by searching pertinent and available papers on PubMed, ClinicalKey and Scielo platforms with no date restriction, up to 2022. Conclusion: Immunohistochemistry is an important tool that has been integrated into conventional histopathology and provides diagnostic assistance in the interpretation of common but equivocal neoplasms

Antecedentes: El uso de la inmunohistoquímica ha tenido un gran impacto en el diagnóstico de patología oral y maxilofacial. Como técnica, determina la distribución y la cantidad de ciertas moléculas celulares a través de una reacción antígeno-anticuerpo específica. Aunque en la mayoría de los casos se logra obtener un diagnóstico definitivo basado en el análisis cito morfológico con hematoxilina y eosina, junto con las características clínicas y radiológicas, algunas neoplasias microscópicamente equívocas deben evaluarsemás a fondo con inmunohistoquímica. Objetivo: Este artículo revisa los fundamentos básicos actuales de la técnica y su relevancia en el diagnóstico de algunas lesiones orales y maxilofaciales frecuentemente tratadas en la práctica clínica diaria. Materiales y Métodos: Se realizó una búsqueda y revisión de artículos científicos relacionados con el uso immunohistoquímica en patología oral y maxilofacial en PubMed, ClinicalKey y Scielo. Conclusión: La immunohistoquimica es una herramienta importante que ha sido integrada a la histopatología convencional y brinda asistencia diagnostica en la interpretación de neoplasias comunes pero equívocas

Case presentation. A A 52-year-old male patient presented to the urology office with a two-year history of noticing a bright red, pruritic, and painful lesion on the glans and foreskin with a progressive increase in size that did not improve with antibiotic and antifungal treatments. Treatment. Partial glandectomy with thigh skin graft was performed. Outcome. After After one month, the graft presented a 95 % of coupling. No local recurrence of cancer was observed. The histopathological study reported invasive squamous cell carcinoma in the lesion of the foreskin and glans skin, with all surgical margins, lateral and deep limits, negative for malignancy. After eight months post-surgery, the covering of the glans was observed with an appropriate esthetic result, with a similar appearance to the natural covering

Predição de risco de falha clínica baseada na detecção de biomarcadores tumorais em câncer de cavidade bucal / Biomarkers analysis for risk prediction of clinical failure in patients diagnosed with oral cavity cancer

INTRODUÇÃO: O carcinoma de células escamosas da cavidade oral (CEC) abrange uma ampla diversidade de células neoplásicas que possuem características moleculares heterogêneas quando expressadas pelo tumor, cuja detecção primária pode se tornar uma ferramenta útil tanto no diagnóstico inicial quanto no prognóstico nos pacientes portadores deste câncer. Os principais biomarcadores tumorais (BmTs) descritos e associados à carcinogênese do câncer de cavidade oral são: p53, p16, Ciclina-D1, EGFR e a E-caderina. OBJETIVO: O objetivo deste estudo foi avaliar o risco de recorrência a partir da detecção dos BmTs p16, p53, E-caderina, Ciclina-D1 e EGFR nos pacientes portadores de CEC submetidos ao tratamento multimodal. MATERIAL E MÉTODOS: Foram selecionados 100 pacientes com diagnóstico de CEC de cavidade oral e submetidos ao tratamento multimodal, os quais foram separados em dois grupos: A) Pacientes com CEC de assoalho de boca; B) Pacientes com CEC de língua, ambos os grupos tratados de forma multimodal. Após seleção foi realizada a análise por imunoistoquímica (IHQ) da expressão dos 05 biomarcadores acima descritos. Da mesma forma, foi realizada a análise dos dados demográficos e clínicos, além dos critérios morfológicos inerentes ao tumor para determinação dos fatores preditivos e prognósticos independentes. RESULTADOS: Após a análise retrospectiva dos dados da população de estudo, 51 pacientes (51%) apresentaram CEC na região do assoalho de boca e 49 (49%) na língua, com maior proporção de homens do que mulheres (69 % vs. 31%) e com idade maior ou igual a 60 anos (mediana: 62 anos/ R: 29-86 anos). A mediana de acompanhamento dos pacientes foi de 28 meses (R: 0-71 meses/média: 26 /DP: +-14,04) e do aparecimento da recorrência foi de 12 meses (mediana: 9 meses/ R: 0-37 meses). A maioria apresentou o estadiamento clínico-patológico inicial I e II (63,6%), pior padrão de infiltração tipo 3-5 (70,5%) e com presença de extensão extracapsular (EEC) (57,5%). Por outro lado, 21 pacientes (21,2%) expressaram p16, 87 (87,9%) a Ciclina-D1, 63 (63%) p53, 53 (53,5%) a E-caderina e 66 (66%) o EGFR. Após aplicação do teste Qui-quadrado foi observada associação estatisticamente significativa entre a expressão do p53 e o sexo (p: 0,01), p53 e tabagismo/etilismo (p: 0,04) e a expressão da E-caderina associada à presença de infiltrado linfoide (p: 0,03). Para análise da Sobrevida Global (SG) foi aplicado o teste de Kaplan Meier, sendo que a média foi de 53 meses (R: 42-61 meses). Na análise da Sobrevida Livre de Doença (SLD) a média foi de 31 meses (R: 27-24 meses). Finalmente, foi realizada a análise multivariada de Cox para cálculo da razão de risco (RR), onde foram observados para o EGFR RR: 4,97 (p: 0,016/R: 1,34-18,30) e a E-caderina RR: 0,294 (p: 0,056/ R: 0.084-1.03). CONCLUSÃO: A expressão de EGFR resultou como potencial biomarcador preditivo de risco de recorrência nos pacientes com CEC de cavidade oral e submetidos à abordagem multimodal, enquanto a E-caderina comportou-se como provável fator protetor contra o risco de recorrência neste mesmo grupo. Contudo, uma avaliação com maior coorte de pacientes se torna necessária para melhor compreensão do papel de outros BmTs, bem como a validação destes resultados na prática clínica.

INTRODUCTION: Oral Squamous Cell Carcinoma (OSCC) is the sixth most common cancer worldwide, characterized by heterogeneous cellular and histological features observed by different molecular parameters. The main biomarkers (BKs) associated with oral cavity tumorigenesis are p53, EGFR, Cyclin-D1, p16 and E-cadherin and their expression is associated with poor prognosis and multiples relapses, besides other histopathological prognostic factors associated to lower rates of overall (OS) and disease-free survival (DFS). OBJECTIVE: This study aims to confirm through histopathological assessment (HP) based on morphological tumor criteria and immunohistochemistry analysis (IHC) of the BKs the association with increased local recurrence in patients diagnosed with OSCC submitted to multimodal treatment at A.C. Camargo Cancer Center. MATERIAL AND METHODS: One hundred patients diagnosed with OSCC submitted to multimodal treatment during 2013-2017 were evaluated and distributed in two groups according to the primary local tumor: A) Patients with OSCC in the floor of the mouth and B) tongue OSCC, both groups treated with only surgery, surgery plus radiotherapy (RT) and/or surgery with RT and chemotherapy. IHC and HP analysis were performed of surgical specimen for detection of these five BKs such as EGFR, p53, E-cadherin, p16 and Cyclin D1. Moreover, after HP for morphological tumor featuring prognostic factors such as clinic-pathological staging, free surgical margins, extracapsular extension of lymph nodes, perineural and angiolymphatic invasion, depth of pattern infiltration were described. Demographic and clinical data were collected, and the nonparameter Chi-square statistical test was performed for determining association between them. OS and DFS rates were calculated using Kaplan Meier test and logRank test for univariate statistical analysis. Cox regression model was done, and the hazard ratio was established for each independent factor to predict clinical failure (p<=0.05). RESULTS: From 100 patients analyzed, 61% were male and 39% female. Regarding local primary tumor, 51% presented OSCC in the floor of the mouth and 49% in the tongue with a mean age of 62 years (R: 29-86). The median of follow-up was 28 months (mean: 26 / SD: +-14,04 / R: 0-71) and the mean of recurrence appearance was 12 months (median: 9/ R: 0-37). Most patients showed an initial stage (I-II) (63.6%), Worst pattern of invasion (WPOI) 3-5 (70.5%), extracapsular extension (EE) (57.5%). Regarding BKs expression, 21.2% p16, 87.9% Cyclin-D1, 63% p53, 53.5% E-cadherin, and 66% EGFR. It was observed a statistically significant association between p53 expression and for both sex (p: 0.01), p53 and smoking/alcohol consumption (p:0.04). E-cadherin was associated with lymph node infiltration (p: 0.03). The median OS was 80% vs 60% in 03 years (R: 42-61; I/II vs. III-IV p: 0.06); for DFS was 50% (p:0.22; I/II vs. III/IV) in 05 years (R: 27-24). Cox regression showed that EGFR expression HR: 4.9 (p: 0.02/ R: 1.34-18.30) and E-cadherin HR: 0.3 (p: 0.06/R: 0.084-1.03) and EE as morphological tumor criteria (HR: 3.68 / p: 0.056 / R: 1.00-13.48) are independent factors for prediction of clinical failure. CONCLUSION: EGFR expression is a potential biomarker for prediction of oral cancer recurrence in patients submitted to multimodal management; however, the loss of E-cadherin expression was considered as a protective factor against OSCC recurrence for this group. Furthermore, longitudinal studies must be performed to validate these results in the clinical practice

Spray de barreira para prevenir o apagamento da marcação cirúrgica na cirurgia micrográfica de Mohs / Barrier spray to prevent surgical marking erasure in Mohs micrographic surgery

A preservação do desenho das margens cirúrgicas é essencial durante a realização da cirurgia micrográfica de Mohs. Contudo, a degermação cutânea no ato da antissepsia e o uso da gaze durante a anestesia local, com frequência, promovem a remoção dessas marcações. A utilização da película protetora Cavilon® 3M, ao fixar a tinta da caneta marcadora, mostrou-se eficaz na preservação do mapa cirúrgico, permitindo uma remoção precisa do espécime cirúrgico

The preservation of the surgical margins marking is essential during Mohs micrographic surgery. However, skin degermation during antisepsis and the use of gauze during local anesthesia often remove these markings. The use of the protective film Cavilon® 3M to fix the marking pen ink was effective in preserving the surgical map, allowing an accurate removal of the surgical specimen.

Anal cancer in systemic lupus erythematosus patients is a neglected condition / Câncer anal em pacientes com lúpus eritematoso sistêmico é uma condição negligenciada

Patients with systemic lupus erythematosus have a higher incidence of neoplasms associated with human papillomavirus infections, such as those that affect the vulva, the vagina, and the cervix; however, little is known about the frequency of anal cancer among these patients. Although there are recommendations for screening for this cancer in immunosuppressed individuals, it is possible that this procedure is not strictly followed. We describe the case of a 47-year-old woman with systemic lupus erythematosus who was treated with immunosuppressants and developed advanced anal squamous cell carcinoma after adequate treatment and healing of a high-grade cervical squamous intraepithelial lesion. Five years after the completion of the anal cancer treatment, the patient presented with cystic hepatic lesions that were histopathologically confirmed to be metastatic squamous cell carcinoma. This report aimed to highlight the need for anal cancer screening in patients with lupus, particularly if there was a history of cervical cytopathological alterations. (AU)

Resumo Pacientes com lúpus eritematoso sistêmico apresentam maior incidência de neoplasias associadas a infecções por HPV, como aquelas que acometem a vulva, a vagina e o colo do útero, mas pouco se sabe sobre a frequência de câncer anal entre essas pacientes. Embora existam recomendações para o rastreamento desse câncer em indivíduos imunossuprimidos, é possível que esse procedimento não esteja sendo rigorosamente seguido. Descrevemos uma mulher de 47 anos com lúpus eritematoso sistêmico, tratada com imunossupressores, que desenvolveu um carcinoma escamocelular anal avançado após tratamento adequado e cicatrização de lesão intraepitelial escamosa cervical de alto grau. Cinco anos após o término do tratamento do câncer anal, a paciente apresentou lesões císticas hepáticas cujo resultado citopatológico confirmou ser carcinoma escamocelular metastático. O presente relato teve como objetivo chamar atenção para a necessidade do rastreamento do câncer anal em pacientes com lúpus, principalmente se houver história prévia de alterações citopatológicas cervicais.

Carcinoma de células escamosas de pene

Introducción: El cáncer de pene es una neoplasia maligna poco frecuente en todo el mundo; representa el 1 % de todos los cánceres que afectan a los hombres. Es una neoplasia caracterizada por un proceso proliferativo de células epiteliales, originándose a partir de la piel del prepucio interno o del glande, que se identifica por un crecimiento invasivo y diseminación metastásica temprana a ganglios linfáticos. Objetivo: Exponer la presentación clínica, diagnóstico y tratamiento de un hombre joven con cáncer de pene. Caso clínico: Paciente masculino de 31 años de edad, color de la piel blanca, con antecedentes de salud anterior y de procedencia urbana; que desde hace dos años presenta lesión ulcerosa, descamativa, granulosa en el pene; no dolorosa, con secreciones fétidas y que ha ido aumentando de tamaño. Con la aplicación de anestesia regional espinal se realizó penectomía parcial y se confirmó el diagnóstico de un carcinoma de células escamosas de pene. Conclusiones: El carcinoma de células escamosas de pene es infrecuente en hombres jóvenes y de buen pronóstico si es diagnosticado a tiempo y para cuyo diagnóstico se precisa ser especialmente estricto con los criterios histológicos. La penectomía parcial es el tratamiento de elección de la lesión primaria. El seguimiento de estos pacientes es fundamental para actuar de forma rápida ante la presencia de recidiva o adenopatías metastásicas.

Introduction : Cancer of the penis is a rare malignant neoplasm worldwide; it represents 1 % of all cancers that affect men. It is a neoplasm characterized by a proliferative process of epithelial cells, originating from the skin of the inner prepuce or glans penis, which is identified by invasive growth and early metastatic spread to lymph nodes. Objective : To expose the clinical presentation, diagnosis and treatment of a young man with penile cancer. Clinical case : Male patient 31 years of age, white skin color, with a history of previous health and urban origin; that for two years has had ulcerative, decamative, granulous lesion on the penis; not painful, with fetid secretions and that has been increasing in size. With the application of regional spinal anesthesia, partial penectomy was performed and the diagnosis of squamous cell carcinoma of the penis was confirmed. Conclusions : Squamous cell carcinoma of the penis is uncommon in young men and has a good prognosis if it is diagnosed early and for whose diagnosis it is necessary to be especially strict with the histological criteria. Partial penectomy is the treatment of choice for the primary lesion. The follow-up of these patients is essential to act quickly in the presence of recurrence or metastatic adenopathies.

Carcinoma epidermoide sarcomatoso metastásico a la placenta: un reporte de caso / Metastatic sarcomatosus squamous carcinoma to the placenta: a case report

Resumen ANTECEDENTES: El cáncer epidermoide cutáneo de tipo sarcomatoide es una neoplasia rara, de bajo riesgo de malignidad, con menos del 2% de riesgo de metástasis. Su comportamiento agresivo es inusual y casi siempre asociado con factores que favorecen su malignidad. La metástasis a la placenta es también excepcional: hasta la actualidad solo se han reportado 61 casos. CASO CLÍNICO: Paciente de 35 años con antecedentes de dos embarazos, en curso de las 33 semanas de gestación, carcinoma epidermoide infiltrante en la pierna izquierda, con amputación supracondílea y metástasis pulmonar. Ingresó a urgencias por dificultad respiratoria, sin trabajo de parto, taquicárdica y taquipneica. Se decidió la cesárea con obtención de nacido vivo, de sexo femenino, 1860 g, sin complicaciones. Luego de la intervención, la paciente fue trasladada a una institución especializada en atención oncológica, donde falleció a las 24 horas. La recién nacida se dio de alta sin complicaciones y sin manifestaciones oncológicas o de otro tipo hasta el año de nacida. CONCLUSIONES: Luego de una búsqueda exhaustiva en la bibliografía los autores consideran que el caso aquí comunicado es el primero en Perú de cáncer epidermoide cutáneo de tipo sarcomatoide con metástasis a la placenta.

Abstract BACKGROUND: Sarcomatoid cutaneous epidermoid cancer is a rare neoplasm, with a low risk of malignancy and less than 2% risk of metastasis. Its aggressive behavior is unusual and almost always associated with factors favoring its malignancy. Placental metastasis is also exceptional: only 61 cases have been reported to date. CLINICAL CASE: 35-year-old female patient, with a history of two pregnancies, in 33 weeks of gestation, infiltrating squamous cell carcinoma of the left leg, with supracondylar amputation and pulmonary metastasis. She was admitted to the emergency room for respiratory distress, without labor, tachycardic and tachypneic. It was decided to perform a cesarean section with live birth, female, 1860 g, without complications. After the intervention, the patient was transferred to an institution specialized in oncologic care, where she died 24 hours later. The newborn was discharged without complications and without oncologic or other manifestations up to one year of age. CONCLUSIONS: After an exhaustive search of the literature, the authors consider the case reported here to be the first case of sarcomatoid epidermoid skin cancer with metastasis to the placenta.

Epidemiological study of penile cancer in a northeastern state - Brazil / Estudo epidemiológico do câncer de pênis em um estado do Nordeste - Brasil

ABSTRACT Objective: to trace the clinical and epidemiological profile of penile cancer in Rio Grande do Norte/Brazil and relate them to data published in the literature. Methods: a cross-sectional study was conducted with 94 patients diagnosed with penile cancer in 2011-2018, treated at the Liga Norte Riograndense Contra o Cancer. Results: all patients were diagnosed with squamous cell carcinoma, mainly aged over 50 years, from the states interior, brown, illiterate, or with incomplete primary education. At diagnosis, 68% of patients were classified as having tumors =T2, and 30% had lymph node involvement. Distant metastases were detected in 2.1% of patients at diagnosis. Most patients received the diagnosis in the initial phase of the disease, but 20.2% were diagnosed in stage IV. Partial penectomy was the most performed surgery, and 10% of patients relapsed, mainly in the lymph nodes (87.5%). The mean follow-up of the patients was 18 months, with an estimated overall survival at five years of 59.1%. However, 25% of patients were followed up for up to 3 months, losing follow-up. Conclusion: the State of Rio Grande do Norte has a high incidence of penile cancer with a high frequency of locally advanced tumors at diagnosis and in younger patients younger than 50. Furthermore, socioeconomic factors interfere with early diagnosis and hinder access to specialized services.

RESUMO Objetivo: traçar o perfil clínico e epidemiológico do câncer de pênis no Rio Grande do Norte/Brazil e relacioná-los com dados publicados na literatura. Métodos: realizou-se estudo transversal de 94 pacientes diagnosticados com câncer de pênis no período de 2011-2018, tratados na Liga Norte Riograndense Contra o Câncer. Resultados: todos os pacientes foram diagnosticados com carcinoma espinocelular, principalmente com idade acima dos 50 anos, provenientes do interior do estado, pardos, analfabetos ou com ensino fundamental incompleto. Ao diagnóstico, 68% dos pacientes foram classificados com tumores =T2 e 30% possuiam envolvimento linfonodal. Metástases à distância foram detectadas em 2,1% dos pacientes ao diagnóstico. A maioria dos pacientes recebeu o diagnóstico na fase inicial da doença, mas 20,2% foram diagnosticados em estádio IV. Penectomia parcial foi a cirurgia mais realizada e 10% dos pacientes recidivaram, principalmente para linfonodos (87,5%). A média de seguimento dos pacientes foi de 18 meses, apresentando estimativa de sobrevida global em 5 anos de 59,1%. No entanto, 25% dos pacientes foram acompanhados por até 3 meses, perdendo o seguimento. Conclusão: o Estado do Rio Grande do Norte apresenta elevada incidência de câncer de pênis com alta frequência de tumores localmente avançados ao diagnóstico, assim como em pacientes mais jovens, menores que 50 anos de idade. Outrossim, o fator socioeconômico interfere no diagnóstico precoce e dificulta o acesso a serviços especializados. .
