Sonidegib as a Locally Advanced Basal Cell Carcinoma Therapy in Real-life Clinical Setting: A National Multicentre Study. / [Artículo traducido] Sonidegib para el tratamiento del carcinoma basocelular avanzado en práctica clínica real: estudio nacional multicéntrico.

BACKGROUND: Basal cell carcinoma (BCC) is the most prevalent cancer. A minority of BCCs have an aggressive behaviour (laBCC) and may require hedgehog pathway inhibitors such as sonidegib as its treatment. OBJECTIVE: To describe the use of sonidegib in a large number of patients and provide more data on its real-life efficacy and safety profile. METHODS: We conducted a retrospective and multicentric study that included patients treated with sonidegib. Epidemiological, effectiveness and safety data were collected. RESULTS: A total of 82 patients with a mean age of 73.9 years were included. Ten patients had Gorlin syndrome. Median treatment duration was 6 months. Median follow-up duration was 34.2 months. Globally, 81.7% of the patients showed clinical improvement (52.4% partial response and 29.3% complete response), 12.2% clinical stability and 6.1% disease progression. There was no statistically significant difference in clinical improvement between the 24 h and 48 h sonidegib posology. After 6 months of treatment, 48.8% of the patients discontinued sonidegib. Prior vismodegib treatment and recurrent primary BCC were associated with a poorer response to sonidegib. At 6 months of treatment, 68.3% of the patients experienced at least one adverse effect. CONCLUSION: Sonidegib shows good effectiveness and acceptable safety profile in usual clinical practice.

Skin Flaps for the Repair of Multiple Adjacent Tumors.

In daily clinical practice, the dermatologic surgeon frequently has to excise closely adjacent tumors in the facial region. In such cases, planning of an appropriate reconstruction technique is essential. The aim is to treat all of the lesions in a single surgical intervention, if possible, and to achieve a good functional and cosmetic outcome. We present 5 patients in whom a single flap was used to repair multiple adjacent defects.

Subcutaneous pedicled V-Y advancement flap for surgical reconstruction of the auricle of the ear.

The subcutaneous pedicled V-Y advancement flap is useful for the repair of small and medium-sized defects in areas where it is easy to obtain a good subcutaneous pedicle (upper lip, cheek, eyebrow, and nasal tip and ala). The almost complete absence of subcutaneous tissue on the anterior aspect of the auricle of the ear can limit the use of this approach in this region. We present 4 patients in whom subcutaneous pedicled V-Y advancement flaps were used to repair surgical defects of the helix, scaphoid fossa, and antitragus, achieving a good functional and aesthetic result in all cases.

Risk factors for squamous cell carcinoma, a study by the National Dermatology Centre of Colombia.

INTRODUCTION: Nonmelanoma skin cancer is the most common malignancy in white individuals. The risk factors for squamous cell carcinoma, which belongs to the family of nonmelanoma skin cancers, have not been studied in Colombia. OBJECTIVE: To determine the risk factors for squamous cell carcinoma in patients at a national referral center for skin diseases in Colombia. MATERIAL AND METHODS: We conducted a case-control study that evaluated sociodemographic, epidemiological, and clinical factors among 332 individuals. Risk was calculated as odds ratio (ORs) using the multivariate conditional logistic regression analysis method. RESULTS: The following risk factors were identified: family history of skin cancer (OR, 6.55; 95% CI, 1.4-28.9), living in a rural area after the age of 30 years (OR, 3.13; 95% CI, 1.3-7.2), a lifetime working outdoors (OR, 2.98; 95% CI, 1.5-5.7), smoking more than 10 cigarettes a day (OR, 2.96; 95% CI, 1.3-6.5), actinic conjunctivitis (OR, 2.68; 95% CI, 1.2-5.9), poikiloderma of Civatte (OR, 3.29; 95% CI, 1.7-6.1), numerous facial actinic keratoses (OR, 9.23; 95% CI, 4.9-17.1), and numerous freckles (OR, 3.68; 95% CI, 1.3-10.1). CONCLUSIONS: We have documented clinical characteristics and personal history factors that should guide the physician in making decisions on the preventive and follow-up measures to be adopted for individuals at risk of squamous cell carcinoma. These findings may help guide policy for controlling the disease using local information.

What Proportion of the Caseload at Dermatology Outpatient Clinics in Spain Do Skin Tumors Account for? Results from the DIADERM National Random Sampling Project. / ¿Cuánta carga asistencial supone la enfermedad tumoral cutánea en la actividad ambulatoria en la Dermatología española? Resultados del muestreo aleatorio nacional DIADERM.

INTRODUCTION AND OBJECTIVE: A significant part of a dermatologist's activity involves the diagnosis and management of tumors. The aim of this study was to analyze the caseload at public and private dermatology outpatient clinics in Spain to determine the proportion of tumor diagnoses. MATERIAL AND METHOD: Observational cross-sectional study of diagnoses made in dermatology outpatient clinics during 2 data-collection periods in the DIADERM study, an anonymous survey of a random, representative sample of dermatologists across Spain. Diagnoses made during the 2 periods were coded according to the CIE-10. There were 165 tumor-related codes, classified into 24 groups. For the purpose of this study, these groups were then reduced to benign melanocytic lesions, malignant melanocytic lesions, benign nonmelanocytic lesions, and malignant nonmelanocytic lesions. RESULTS: Tumors accounted for 46.2% of all diagnoses; 18.5% of the tumors were malignant (a category that included in situ forms of keratinocyte cancers). Four of the 10 most common diagnoses were of malignant tumors: in situ keratinocyte cancers, basal cell carcinoma, melanoma, and squamous cell carcinoma. Significant differences were observed between malignant and benign tumors according to type of practice (public vs. private) and geographic region. CONCLUSION: Skin cancer accounts for a significant part of the dermatologist's caseload in Spain. Differences can be observed depending on the public/private healthcare setting and other factors.

Hydrochlorothiazide treatment and risk of non-melanoma skin cancer: Review of the literature. / Terapêutica com hidroclorotiazida e risco de cancro cutâneo não melanoma: revisão da literatura.

Non-melanoma skin cancer is the most prevalent malignancy in fair-skinned people and its incidence is increasing. Recently, studies have suggested that antihypertensive drugs may increase the risk of these tumors, particularly hydrochlorothiazide, due to its photosensitizing properties. The Portuguese National Authority for Medicines and Health Products, INFARMED, has issued an alert to healthcare professionals concerning the increased risk of non-melanoma skin cancer in patients exposed to cumulative doses of this drug. However, study results have been heterogeneous and sometimes conflicting. The high incidence of non-melanoma skin cancer and the large number of patients under chronic hydrochlorothiazide therapy may thus have important public health consequences. In this article, the authors review the published evidence and conclude that there may be an association between hydrochlorothiazide use and the risk of non-melanoma skin cancer, but also point out some limitations of the studies in the literature. It is important to promote preventive strategies against sun exposure, regular skin examinations, and individual assessment of the benefits of hydrochlorothiazide use, particularly in patients with previous skin cancer.

Total rhinectomy for nasal carcinomas.

INTRODUCTION: Total rhinectomy is an uncommon procedure for the treatment of nasal malignancies, usually reserved for locally advanced tumors. There are few case series studying total rhinectomy in the literature, reporting conflicting results about recurrence and metastasis. OBJECTIVE: Evaluate prognosis of total rhinectomy cases for malignant neoplasia in our institution. METHODS: Retrospective review from January 2013 to September 2018, including all patients undergoing total rhinectomy in our Institution, under the care of the Head and Neck surgical team. RESULTS: Ten patients were included, two men and eight women. The mean patient age was 71.6 years old. The majority had nasal skin (8 cases) carcinomas. Squamous cell carcinoma was present in seven cases. In total, six cases had regional metastasis, in a median period of 14.3 months. The overall mortality and disease specific mortality was 50% and 30%, respectively, in a median follow-up of 45.7 months. CONCLUSION: We observed high overall and disease-specific mortality among cases with advanced nasal malignancies undergoing total rhinectomy.

Carcinoma basocelular de vulva: relato de caso / Basal cell carcinoma of the vulva: case report

Introdução: O carcinoma basocelular (CBC) de vulva é uma condição rara que corresponde a menos de 0,4% dos casos de CBC e de 2% a 4% das neoplasias de vulva. O CBC de vulva é mais comum entre mulheres brancas, multíparas e na pósmenopausa, especialmente na sétima década de vida. O objetivo é relatar um caso de CBC de vulva no qual discutiram-se os aspectos do diagnóstico e tratamento. Relato de Caso: Mulher de 63 anos de idade, G1P1A0, chega ao consultório em janeiro de 2022 para tratamento de lesão persistente em vulva. Realizou-se biópsia incisional que mostrou tratar-se de provável carcinoma basocelular nodular com invasão da derme. A paciente submeteu-se a uma ressecção do tumor com margens macroscópicas livres e sutura primária. A cirurgia não teve complicações no pré-operatório e no pós-operatório. O histopatológico da peça cirúrgica mostrou tratar-se de carcinoma basocelular nodular com área irregular, plana, branco, medindo 0,7x0,4cm, com as margens laterais distando 7,0 e 5,0mm e profundas, 5,9mm; todas livres. Conclusão: O caso relatado é raro, tendo sido o tratamento de ressecção cirúrgica do CBC de vulva com margens bem-sucedido. Catorze meses após a cirurgia, a paciente encontra-se sem evidências de recidiva local ou regional.

Introduction: Basal cell carcinoma (BCC) of the vulva is a rare condition that accounts for less than 0.4% of BCC cases and 2% to 4% of vulvar neoplasms. BCC of the vulva is more common among white, multiparous and postmenopausal women, especially in the seventh decade of life. The aim is to report a case of BCC of the vulva in which aspects of diagnosis and treatment were discussed. Case report: A 63-year-old woman, G1P1A0, arrives at the office in January 2022 for treatment of a persistent lesion on her vulva. An incisional biopsy was performed and showed that it was likely nodular basal cell carcinoma with invasion of the dermis. The patient underwent tumor resection with free macroscopic margins and primary suture. The surgery had no complications preoperatively or postoperatively. The histopathology of the surgical specimen showed that it was a nodular basal cell carcinoma with an irregular, flat, white area, measuring 0.7x0.4cm, with the lateral margins 7.0 and 5.0mm apart and 5.9mm deep; all free. Conclusion: The reported case is rare, with surgical resection of BCC of the vulva with margins being successful. Fourteen months after surgery, the patient has no evidence of local or regional recurrence.

Introdução: Em 1977, a partir dos estudos anatômicos de McCraw et al., passou-se a utilizar o músculo peitoral maior como retalho miocutâneo em ilha. O presente artigo descreve um caso de reconstrução de um defeito da parede anterior do hemitórax direito através do retalho miocutâneo peitoral maior em ilha ipsilateral. Relato do Caso: A.E.S., de 66 anos, sexo masculino foi submetido a ressecção ampla de um carcinoma basocelular infiltrativo recidivante de 13,0 x 8,0cm da região paraesternal direita. O retalho miocutâneo foi transposto através de tunelização subcutânea e as cicatrizes posicionadas em forma de mamaplastia em T invertido. Conclusão: A presente tática cirúrgica é de fácil execução para cirurgiões habituados com reconstrução mamária, apresenta tempo cirúrgico curto e resultado estético-funcional satisfatório.

Introduction: In 1977, based on anatomical studies by McCraw et al., the pectoralis major muscle began to be used as an island myocutaneous flap. The present article describes a case of reconstruction of a defect in the anterior wall of the right hemithorax using the pectoralis major myocutaneous flap in an ipsilateral island. Case Report: AES, 66 years old, male, underwent wide resection of a recurrent infiltrative basal cell carcinoma measuring 13.0 x 8.0 cm in the right parasternal region. The myocutaneous flap was transposed through subcutaneous tunneling and the scars were positioned in the shape of an inverted T mammoplasty. Conclusion: This surgical tactic is easy to perform for surgeons accustomed to breast reconstruction, has a short surgical time, and has satisfactory aesthetic-functional results.

Vitreous metastasis from cutaneous melanoma: diagnosis and management / Metástase vítrea de melanoma cutâneo: diagnóstico e tratamento

ABSTRACT Purpose: To report the clinical findings, treatments, and outcomes in a series of patients with vitreous metastasis from cutaneous melanoma. Methods: This single-center, retrospective, interventional case series included patients with biopsy-confirmed vitreous metastasis from cutaneous melanoma diagnosed between 1997 and 2020. Standard 23- or 25-gauge pars plana vitrectomy was performed for diagnostic sampling. Sclerotomies were treated with double or triple freeze-thaw cryotherapy. Perioperative intravitreal injections of melphalan (32 µg/0.075 mL) were administered, when indicated. Visual acuity, intraocular pressure, and systemic and ocular treatment responses were reported. Results: Five eyes of five patients with unilateral vitreous metastasis from cutaneous melanoma were identified. The median age at diagnosis was 84 (range, 37-88) years. The median follow-up after ophthalmic diagnosis was 28 (8.5-36) months; one patient did not have a follow-up. The initial visual acuity ranged from 20/30 to hand motions. Baseline clinical findings included pigmented or non-pigmented cellular infiltration of the vitreous (5/5), anterior segment (4/5), and retina (3/5). Four patients had secondary glaucoma. Systemic therapy included checkpoint inhibitor immunotherapy (n=3, all with partial/complete response), systemic chemotherapy (n=2), surgical resection (n=3), and radiation (n=2). The median time from primary diagnosis to vitreous metastasis was 2 (2-15) years. One patient had an active systemic disease at the time of vitreous metastasis. The final visual acuity ranged from 20/40 to no light perception. Ophthalmic treatment included vitrectomy in all five patients, intravitreal administration of melphalan in three, and intravitreal administration of methotrexate in one. One patient required enucleation, and histopathology revealed extensive invasion by melanoma cells. Conclusions: Vitreous metastasis from cutaneous melanoma can present as a diffuse infiltration of pigmented or non-pigmented cells into the vitreous and may be misdiagnosed as uveitis. Diagnostic pars plana vitrectomy and periodic intravitreal chemotherapy may be indicated.

RESUMO Objetivo: Descrever os achados clínicos, tratamentos, e desfechos em uma série de pacientes com me tástases vítreas de melanoma cutâneo. Métodos: Série retrospectiva de casos de único centro com intervenção. Pacientes incluídos tiveram seu diagnóstico de MVMC confirmado por biópsia entre 1997 e 2020. Vitrectomia via pars plana com 23 ou 25 gauge foram realizadas para obter espécimens. Esclerotomias foram tratadas com crioterapia em duplo ou triplo congelamento. Injeção intravítrea perioperatória de melfalano (32 ug/0,075 mL) foi administrada quando necessário. Foram relatados acuidade visual, pressão intraocular, resposta terapêutica sistêmica e ocular. Resultados: Cinco olhos de 5 pacientes com metástases vítreas de melanoma cutâneo unilateral foram identificados. Idade média de diagnóstico foi 84 anos (variando de 37-88). Seguimento médio após diagnóstico oftalmológico foi 28 (8,5-36) meses; 1 paciente não teve acompanhamento. Acuidade visual inicial variou de 20/30 a movimentos de mão. Achados clínicos iniciais incluíram infiltração de células pigmentadas e não-pigmentadas no vítreo (5/5), segmento anterior (4/5), e retina (3/5). Quatro pacientes tiveram glaucoma secundário. Tratamento sistêmico incluiu imunoterapia com inibidores da via de sinalização (3 - todos com resposta parcial/completa), quimioterapia sistêmica (2), ressecção cirúrgica (3), e irradiação (2). Intervalo médio entre diagnóstico primário e metástases vítreas foi 2 (2-15) anos. Um paciente teve doença sistêmica ativa simultânea as metástases vítreas. Acuidade visual final variou entre 20/40 e SPL. Tratamento oftalmológico incluiu vitrectomia nos 5 pacientes, melfalano intravítreo em 3 e metotrexato intravítreo em 1. Um paciente precisou de enucleação. A histopatologia revelou invasão celular extensa de melanoma. Conclusões: Metástases vítreas de melanoma cutâneo pode se manifestar como uma infiltração difusa de células pigmentadas e não-pigmentadas no vítreo e erroneamente diagnosticada como uveites. Vitrectomia diagnóstica e quimioterapia intravítrea periódica podem estar indicadas.

Evaluation of the treatment of head and neck cutaneous squamous cell carcinoma in the elderly: a survival analysis. / Evaluación del tratamiento del carcinoma epidermoide cutáneo de cabeza y cuello en la edad avanzada. Análisis de la supervivencia.

INTRODUCTION: It is unknown whether cervical lymphadenectomy as a treatment for cutaneous squamous cell carcinoma of the head and neck (cSCCh&n) increases survival in elderly patients. The aim of this study is to determine whether this procedure has an influence on the survival of these patients, and whether the Short-Form Charlson Comorbidity Index (CCI-SF) can be used as an alternative to age in the surgeon's estimation of elderly patient mortality. METHODS: The study population included all patients diagnosed with cSCCh&n consecutively treated between 2006 and 2011. Non-invasive, non-cutaneous carcinomas were excluded. Patients were grouped according to their age (<70, 70-79, 80-89, >90), CCI-SF (<3, ≥3) and presence (N1) or absence (N0) of cervical metastases. The dependent variable was the performance or not of cervical lymphadenectomy. A univariate survival analysis was performed according to the presence of metastases, a bivariate analysis for each of the independent variables according to the received treatment and a multivariate analysis. RESULTS: 416 cases were included. The mean survival time was greater in the N0 group. For each of the groups based on the presence of metastasis, the differences in the mean survival time according to age and CCI-SF were not significant, regardless of the treatment received. The multivariate analysis showed the influence of age (p=0.0001, OR=1.488, 95%CI=[1.318; 1.679]) and CCI-SF (p=0.001, OR=1.817, 95%CI=[1.257; 2.627]) in the N0 group. In the N1 group only regional treatment has a positive influence on survival (p=0.048, OR=0.15, 95%CI=[0.023; 0.981]). CONCLUSIONS: CCI-SF and age are good mortality indicators in cSCCh&n N0 patients, but not so in cSCCh&n N1 patients. In cSCCh&n N1 patients, regional treatment has a positive influence on survival. Differences cannot be affirmed in the mean survival time of patients with cSCCh&n, based on the development of metastases and the treatment given. New studies will be necessary.

Efectividad y seguridad de la electroacupuntura en el paciente con cáncer de piel / Effectiveness and Safety of Electroacupuncture in the Patient with Skin Cancer

Introducción: La electroacupuntura induce la liberación de encefalina y b- endorfina. Objetivo: Evaluar la efectividad y seguridad de la electroacupuntura auricular para la analgesia posoperatoria en los pacientes electivos con diagnóstico quirúrgico de cáncer de piel. Métodos: Se realizó un estudio cuasi- experimental de intervención terapéutica en los pacientes electivos con diagnóstico de cáncer de piel, en el Hospital Provincial Docente de Oncología "María Curieˮ de Camagüey, en el período comprendido de enero de 2019 a enero de 2022. El universo fue de 200 pacientes, se constituyeron dos grupos, el grupo experimental integrado por 81 pacientes a los que se les aplicó electroacupuntura auricular preoperatoria y el grupo control formado por 119 pacientes a los que se les aplicó el tratamiento convencional. Resultados: Se observó predominio de la edad entre 55 a 59 años para ambos grupos de pacientes. Con la prueba estadística se planteó con un 95 % de confiabilidad que la intensidad del dolor posoperatorio cambio en relación al tratamiento empleado. La mayor parte de los pacientes tratados previamente con electroacupuntura auricular no presentó dolor en el posoperatorio (p = 0,000). El tratamiento impuesto guarda relación estadística significativa con la presencia de complicaciones posoperatorias relacionadas con el dolor, p ≤ 0,05. Se demostró la efectividad analgésica de la electroacupuntura (p = 0,000). Conclusiones: La electroacupuntura auricular para la analgesia posoperatoria en pacientes operados electivos de cáncer de piel, es eficaz y segura.

Introduction: Electroacupuncture induces enkephalin and b-endorphin release. Objective: To assess the effectiveness and safety of auricular electroacupuncture for postoperative analgesia in elective patients with a surgical diagnosis of skin cancer. Methods: A quasiexperimental study of therapeutic intervention was carried out in elective patients with skin cancer diagnosis, at María Curie Provincial Teaching Oncology Hospital of Camagüey, from January 2019 to January 2022. The study universe was two hundred patients. Two groups were made up: the experimental group, integrated by 81 patients, to whom preoperative auricular electroacupuncture was applied; and the control group, made up of 119 patients, to whom conventional treatment was applied. Results: Predominance of age between 55 and 59 years was observed for both groups of patients. The statistical test showed, with a reliability of 95 %, that the intensity of postoperative pain changed in relation to the used treatment. Most of the patients previously treated with auricular electroacupuncture did not present postoperative pain (p = 0.000). The employed treatment was statistically significant with respect to the presence of postoperative pain-related complications (p ≤ 0.05). The analgesic effectiveness of electroacupuncture was demonstrated (p = 0.000). Conclusions: Auricular electroacupuncture for postoperative analgesia in elective operated patients with skin cancer is effective and safe.

Serratus plane block with sedation for patients submitted to axillary dissection: a prospective case series / Bloqueio do plano do músculo serrátil guiado por ultrassonografia associado à sedação venosa como técnica anestésica em cirurgia de linfadenectomia axilar: uma série de casos prospectiva

ABSTRACT Axillary dissection is a standard surgical procedure for stage III skin and soft tissue tumors and is usually performed under general anesthesia. This study aimed to investigate the feasibility of performing axillary dissection with Serratus muscle plane block plus intravenous sedation. Fifteen patients undergoing axillary dissection were prospectively recruited. The patients were evaluated during their pre-operative anesthetic appointment, during their procedure, and at post-operative days 1 and 30. The blockade was performed superficial to the Serratus muscle at the level of fourth rib. Sedation was performed using propofol, fentanyl, dexmedetomidine, and S-ketamine. None of the patients required conversion to general anesthesia. Surgeons showed a highly positive response when asked about the anesthetic technique, and most of them found the technique "indistinguishable" from general anesthesia. The median (interquartile range) pain scores at rest over all time frames was 0 (0-0). Furthermore, no patients developed nausea, hemodynamic instability, or any complications associated with the technique. The Serratus plane block associated with intravenous sedation proved feasible for axillary lymphadenectomy, however, further clinical trials should evaluate potential advantages compared to other techniques.

RESUMO A linfadenectomia axilar é um procedimento cirúrgico padrão para tratamento de tumores de pele e partes moles no estádio III e usualmente é realizada sob anestesia geral. A presente serie de casos prospectiva tem por objetivo investigar a viabilidade da realização da linfadenectomia axilar com o uso do bloqueio do plano do músculo serrátil anterior associado a sedação endovenosa. Foram incluídos 15 pacientes no estudo. Os participantes foram recrutados e avaliados durante consulta pré-anestésica ambulatorial, acompanhados durante o dia da cirurgia, no primeiro e no trigésimo dias de pós-operatório. O bloqueio foi realizado anterior ao músculo serrátil anterior ao nível da quarta costela na linha axilar média. A sedação foi realizada com o uso de propofol, fentanil, dexmedetomidina e dextrocetamina. Não houve necessidade de conversão para anestesia geral em nenhum paciente. Os cirurgiões apresentaram resposta altamente positiva quando questionados sobre a técnica anestésica, considerando na maior parte dos casos "indistinguível" da anestesia geral. A mediana (intervalo interquartil) da dor em repouso em todos os momentos avaliados foi 0 (0-0). Além disso, nenhum paciente desenvolveu náuseas, vômitos, instabilidade hemodinâmica ou qualquer complicação relacionada à técnica empregada. O bloqueio do plano do músculo Serrátil anterior associado a sedação venosa se mostrou viável para execução de linfadenectomia axilar, entretanto ensaios clínicos adicionais são necessários para avaliar potenciais vantagens em comparação com outras técnicas.

Reconstrucción palpebral postumorectomía. Presentación de un caso / Lower eyelid reconstruction after lumpectomy. A case report

Algunos pacientes en la tercera edad desarrollan con frecuencia diversas enfermedades, entre ellas se encuentra el cáncer de piel y la predisposición a la aparición de tumores, tanto en los párpados como en la conjuntiva. Entre los tumores epiteliales malignos se destacan: el carcinoma basocelular y el carcinoma epidermoide; con menor frecuencia, el carcinoma de células de Meibomio y el melanoma palpebral, y raramente, el carcinoma de células de Merkel. Por esta causa, se realizó la presentación de un caso clínico que recibió tratamiento en el Servicio de Cirugía Plástica del Hospital Vladimir Ilich Lenin, de Holguín, al cual se le aplicó la técnica de Mustardé por presentar tumor del párpado inferior. El objetivo fue presentar un paciente con reconstrucción palpebral postumorectomía y mostrar su resultado funcional y estético postoperatorio. Este caso evolucionó satisfactoriamente, sin aparición de complicaciones transoperatorias o postoperatorias.

Some elderly patients frequently develop various diseases, including skin cancer as well as a predisposition to the appearance of tumours, both in the eyelids and conjunctiva. Basal cell carcinoma and epidermoid carcinoma stand out among the malignant epithelial lesions; meibomian cell carcinoma and palpebral melanoma which are less common, and Merkel cell carcinoma rarely known. We present a male patient who received treatment in the plastic surgery service at "Vladimir Ilich Lenin" Hospital, in Holguín, to which Mustardé technique was applied for a tumour of the lower eyelid. An eyelid reconstruction was performed after lumpectomy which allowed us to show a postoperative functional and aesthetic result. This case evolved satisfactorily, without the appearance of intraoperative or postoperative complications.

Retalho plantar medial para reconstrução de defeitos em calcanhar após ressecção de melanoma lentiginoso acral: Uma série de 7 casos / Medial plantar flap for reconstruction of heel defects after resection of acral lentiginous melanoma: A series of seven cases

Introdução: A reconstrução da região plantar ainda é um dos grandes desafios da cirurgia plástica reconstrutiva. Os tecidos dessa região apresentam características únicas e que são essenciais para a manutenção da funcionalidade do membro. De toda a região plantar, a região do calcanhar é a área de maior sustentação do peso e submetida ao maior impacto. O retalho fasciocutâneo plantar medial é uma das opções reconstrutivas, pois representa tecido semelhante e mantém a sensibilidade para a área receptora. Método: Foi realizado um estudo retrospectivo através da coleta de dados de prontuário de pacientes que realizaram reconstruções da região do calcanhar com retalho plantar medial, no período de julho de 2013 a setembro de 2019. O estudo foi aprovado pelo Comitê de Ética para Análise de Projetos de Pesquisa do HCFMUSP (Número CAAE: 56849422.0.0000.0068). Resultados: A reconstrução de calcanhar após ressecção de melanoma lentiginoso acral foi realizada em 7 pacientes. Complicações cirúrgicas foram observadas em 3 pacientes, sendo que todos eles tinham idade acima de 50 anos e/ou alguma comorbidade associada. Houve 57,1% de complicações, sendo 37,5% relacionadas ao retalho e 12,5% relacionadas à área doadora. Ocorreram 3 necroses totais de retalho (42,9%) e 1 perda total de enxerto na área doadora (14,3%). Conclusão: O retalho plantar medial se apresenta como uma boa alternativa para a realização de reconstruções oncológicas de defeitos na região plantar do pé. Contudo, deve-se ponderar a escolha do paciente ideal e lembrar que a dissecção do seu pedículo vascular não é de fácil execução.

Introduction: Resurfacing the sole is still one of the great challenges of reconstructive plastic surgery. The tissues on the sole of the foot have unique characteristics essential for maintaining the limbs functionality. The heel has the most significant weight support and is subjected to the entire soles greatest impact. The medial plantar artery flap is one of the reconstructive options, as it represents similar tissue and maintains sensitivity to the recipient area. Methods: A retrospective study was performed by collecting data from medical records of patients who underwent reconstructions of the heel with a medial plantar artery flap from July 2013 to September 2019. The study was approved by the Ethics Committee for Analysis of Research Projects of HCFMUSP (CAAE number: 56849422.0.0000.0068). Results: Heel reconstruction was performed in 7 patients after acral lentiginous melanoma excision. Surgical complications were observed in 3 patients, all of whom were aged over 50 years or have associated comorbidity. There were 57.1% of complications, 37.5% related to the flap, and 12.5% related to the donor area. There were three total flap necroses (42.9%) and one total graft loss in the donor area (14.3%). Conclusion: The medial plantar flap presents itself as a good alternative for performing oncological reconstructions of defects in the plantar region of the foot. However, the choice of the ideal patient should be considered and we must remember that the dissection of its vascular pedicle is not easily executed.

Percepción de calidad de vida de pacientes hospitalizados con diagnóstico primario de cáncer y herida tumoral / Perception of quality of life of hospitalized patients with primary diagnosis of cancer and tumor wound

Introducción: las enfermedades oncológicas son la causa de 9.5 millones de muertes en el mundo y la tercera causa de muerte en México. La aparición de heridas tumorales es una complicación de la progresión de la enfermedad oncológica con síntomas que repercuten en la calidad de vida de los pacientes. Objetivo: evaluar la percepción de calidad de vida de pacientes hospitalizados con diagnóstico primario de cáncer y herida tumoral en un hospital de tercer nivel de la Ciudad de México. Metodología: estudio descriptivo que incluyó a 57 pacientes hospitalizados con diagnóstico de cáncer primario y herida tumoral. La percepción de calidad de vida se evaluó con el cuestionario McGill Quality of Life Questionnaire (MQOL) con 4 dimensiones: de bienestar físico, psicológico, existencial y de apoyo social. La herida tumoral se estadificó con la escala Malignant Cutaneous Wound Stating System. La severidad de la enfermedad se midió con la escala APACHE II. El análisis se hizo con estadística descriptiva. Resultados: de 57 pacientes con edad entre 24 y 81 años de edad, predominó el cáncer de mama en 31.5% de mujeres y cáncer de testículo en 10.5% de hombres. La herida tumoral grado IV se presentó en 72% de los pacientes. La percepción de calidad de vida en general, que se midió con el Single ítem scale, fue buena y regular en 38.6 y 26.3%, respectivamente. Conclusiones: para la práctica de enfermería la evaluación de la calidad de vida en las personas con cáncer significa una diversidad de posibilidades para intervenir y promover el bienestar en la persona y la familia.

Introduction: Oncological diseases are the cause of 9.5 million deaths in the world and the third cause of death in Mexico. The appearance of tumor wounds is a complication of the oncological disease progression with symptoms that affect the quality of life of patients. Objective: To evaluate the perception of quality of life of hospitalized patients with a primary diagnosis of cancer and tumor wound in a tertiary care hospital in Mexico City. Methodology: Descriptive study that included 57 hospitalized patients diagnosed with primary cancer and tumor wound. The perception of quality of life was evaluated with the McGill Quality of Life Questionnaire with 4 dimensions: of physical, psychological, and existential well-being, as well as social support. The tumor wound was staged using the Malignant Cutaneous Wound Stating System scale. The severity of the disease was calculated with the APACHE II scale. The analysis was made with descriptive statistics. Results: Out of 57 patients aged 24 to 81 years, breast cancer predominated in 31.5% of women and testicular cancer in 10.5% of men. Grade IV tumor wound occurred in 72% of patients. The perception of quality of life in general, measured with the Single Item Scale, was good and regular in 38.6 and 26.3%, respectively. Conclusions: For nursing practice, the evaluation of the quality of life in people with cancer means a diversity of possibilities to intervene and promote the well-being of the person and the family.

Factores pronósticos de la supervivencia en pacientes con melanoma de piel metastásico, que reciben primera línea de tratamiento con inmunoterapia anti PD-1 o régimen con anti PD-1 y anti CTLA-4, en el Instituto Nacional de Cancerología de Colombia / Prognostic factors for survival in patients with metastatic skin melanoma, receiving first-line treatment with anti-PD-1 or anti-PD-1 and anti-CTLA-4 immunotherapy regimen at the Instituto Nacional de Cancerología (Bogotá, Colombia)

Introducción. En melanoma metastásico, uno de los estándares de tratamiento es la inmunoterapia anti-PD-1 y anti-CTLA-4. El objetivo de esta investigación fue determinar factores pronósticos asociados con la supervivencia de pacientes con melanoma metastásico, con primera línea con inmunoterapia anti-PD-1 o anti-PD-1 y anti-CTLA-4, en el Instituto Nacional de Cancerología de Colombia.Métodos. Se revisaron 63 historias clínicas del Instituto Nacional de Cancerología de enero de 2016 a abril de 2020. Se realizó un análisis de supervivencia con método de Kaplan-Meier, prueba log-rank y regresión de Cox.Resultados. La mayoría de los pacientes fueron mujeres (58,7%); 47,6% tenían subtipo lentiginoso acral, 17,4% BRAF mutado, 20,6% compromiso en SNC, 50,8% recibieron nivolumab, 41,3% pembrolizumab y 7,9% nivolumab + ipilimumab. La mediana de supervivencia libre de progresión fue de 7,3 meses, con una tasa a 1, 2 y 3 años de 38,0%, 22,0% y 12,0% respectivamente; la mediana de supervivencia global fue 12,2 meses con una tasa a 1, 2 y 3 años de 50,0%, 25,0% y 19,0%. Como factor pronóstico protector para SLP se encontró el recibir nivolumab en comparación con pembrolizumab (HR=0,427; IC95% 0,21-0,86) y para SG el estado funcional al diagnóstico (ECOG 2 HR=12,38; IC95% 2,20-69,45).Conclusión. La SLP y SG fueron menores a la de ensayos clínicos aleatorizados en población caucásica, pero similar a la encontrada en estudios que incluyen mayor proporción del subtipo histológico lentiginoso acral, como la nuestra. Se encontraron como factores pronósticos el tipo de inmunoterapia utilizada y el estado funcional al diagnóstico.

Introduction: In metastatic melanoma, one of the standard treatments is anti-PD-1 and anti-CTLA-4 immunotherapy. This research aimed to determine prognostic factors associated with the survival of patients with metastatic melanoma who started first-line treatment with anti-PD-1 or anti-PD-1 and anti-CTLA-4 immunotherapy at the Instituto Nacional de Cancerología (INC) (Bogotá, Colombia).Methods: A total of 63 medical records from the INC were reviewed from January 2016 to April 2020. A survival analysis was performed using the Kaplan-Meier method, log-rank test, and Cox regression.Results: Most patients were women (58.7%); 47.6% had acral lentiginous subtype, 17.4% BRAF-mutated melanoma, 20.6% CNS involvement, 50.8% received nivolumab, 41.3% pembrolizumab, and 7.9% nivolumab + ipilimumab. Median progression-free survival (PFS) was 7.3 months with a rate at 1, 2, and 3 years of 38%, 22%, and 12%, respectively, while median overall survival (OS) was 12.2 months with a rate of 50%, 25%, and 19% at 1, 2, and 3 years, respectively. A protective prognostic factor for PFS was to receive nivolumab compared to pembrolizumab (HR=0.427; CI95% 0.21-0.86), and for OS, functional status at diagnosis (ECOG 2 HR=12.38; CI95% 2.20-69.45).Conclusion: PFS and OS were lower than those of randomized clinical trials in the Caucasian population, but similar to those found in studies that include a higher proportion of the acral lentiginous histological subtype, such as ours. The type of immunotherapy used and functional status at diagnosis were found as prognostic factors

Carcinoma espinocelular sobre cicatriz de fístula arteriovenosa: relato de caso / Squamous cell carcinoma on an arteriovenous fistula scar: case report

Resumo A fístula arteriovenosa (FAV) é o principal acesso para hemodiálise devido à sua patência superior e menores índices de complicação quando comparada aos demais acessos para hemodiálise. Relatamos o caso de uma paciente do sexo feminino, de 69 anos, com doença renal crônica dialítica secundária a nefroesclerose hipertensiva com FAV radio-cefálica no membro superior esquerdo realizada há 9 anos. Há 2 anos, foi submetida a transplante renal e fazia uso de imunossupressores. Evoluiu com aparecimento de lesão crostosa em antebraço esquerdo há 3 meses, foi submetida a biópsia excisional, e foi evidenciado carcinoma espinocelular bem diferenciado e superficialmente invasivo, com margens cirúrgicas laterais e profundas livres de neoplasia. No seguimento de 1 ano, a paciente não apresentava sinais de recidiva neoplásica.

Abstract The main type of access used for hemodialysis is the arteriovenous fistula (AVF) because it offers superior patency and lower complication rates when compared to other hemodialysis accesses. We report the case of a 69-year-old female patient with chronic kidney disease on dialysis secondary to hypertensive nephrosclerosis with a radiocephalic AVF in the left upper limb created 9 years previously. Two years previously, she had undergone a kidney transplant and was taking immunosuppressants. A crusted lesion developed on her left forearm with onset 3 months before presentation and she underwent an excisional biopsy that revealed a well-differentiated and superficially invasive squamous cell carcinoma, with lateral and deep surgical margins free from neoplasia. At 1-year follow-up, the patient showed no signs of neoplastic recurrence.
