RESUMEN
BACKGROUND: Total thyroidectomy is the main line of treatment for papillary thyroid cancer. Central lymph node dissection (CLND) is still debatable. In this study, we aimed to correlate the central lymph node status with the age of patients. METHODS: This is a retrospective study including patients with papillary thyroid cancer (PTC) who underwent total thyroidectomy and CLND at a tertiary cancer center during the period from January 2012 to September 2022. Patients were subdivided into 3groups: patients younger than 20 years old, patients between 20 and 40 years old, and patients older than 40 years old. Correlation between central lymph node status, lateral lymph node status, and harvest count with each other and between age groups was done. RESULTS: 315 patients were included. The younger the age group the higher the possibility of harboring positive central nodes, however, the positivity of lateral nodes was similar. Neither central nodal harvest nor positive central node count significantly differed between groups. The lateral nodal harvest was significantly higher in the < 20 years group with no affection to the number of positive nodes retrieved. The younger the age group the longer the disease-free survival (DFS). CONCLUSION: We can conclude that patients younger than twenty years had a higher probability of harboring malignancy in central nodes and higher lateral node harvest on dissection. In contrast, they do have a lower incidence of recurrence.

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

Stomas are essential for colorectal surgery and are widely used not only for selected cases for bowel obstructions but also in rectal cancer operations to divert stool away from low rectal anastomosis. On the other hand, complications with stomas/ stomas reversal are not uncommon. In this study, we aimed at studying the frequency and the predictors of temporary stomas being permanent, and the contributing factors of surgical stoma/stoma closure related complications. In our cohort, only about 40% of the patient closed their initially planned temporary stomas. The occurrence of intestinal leak, wound sepsis, or any type of morbidity with 30 days of operation were significant predictors of permanent stomas. In addition, alarmingly although Hartmann's procedure was uncommon in our practice, only 9% of those who underwent Hartmann's have had it reversed. Moreover, the only factor that significantly increased stoma related complications was having an end colostomy. There was a tendency toward late closure of stomas with median 8.2 months, however early closure did not correlate to complications. In conclusion, further studies are needed to delineate the low rate of stoma closure. Patients who develop postoperative complications, even wound sepsis, would be at a higher risk of living with permanent stomas. Hartmann's procedures are commonly associated with stoma problems, and reluctance to reverse the stomas. (AU)

Objectives: To study the management of patients with ductal carcinoma in situ (DCIS) and detect the predictors of recurrence and of missing an invasive component in the preoperative biopsy, aiming at guiding tailored treatment of these cases.Materials and methods: A total of 123 cases of DCIS, pure/with invasion, were retrieved from the database of a tertiary cancer hospital in the period from February 2007 to February 2018. Clinical, radiologic & pathologic characteristics and its impact on the surgical management were analyzed.Results: The mean age of the patients was 50.5±12.4 years. The commonest presentation was a palpable mass in 82.9% of the cases. Conservative breast surgery was successfully performed in 15 cases and mastectomy in 108 cases. Recurrence was reported in 11 cases. The underestimation rate in core needle biopsy was 48.9% missing invasive component within diagnosed malignant lesions and 19.6% missing the diagnosis of malignancy. On the other hand, overtreatment was noted as regard surgical procedure and adjuvant therapies.Conclusions: Mastectomy still the most common surgical treatment of DCIS and unfortunately sentinel lymph node biopsy is still underused. Underestimation of invasive component can occur in at least 1/4 of the patients, complexing the treatment plan. Overtreatment with axillary surgery, chemotherapy or radiotherapy needs governance.

Objetivos: Estudiar el manejo de pacientes con carcinoma ductal in situ (CDIS) y detectar los predictores de recaída y de ausencia de un componente invasivo en la biopsia preoperatoria, con el objetivo de orientar el tratamiento a medida de estos casos.Materiales y métodos: Se recuperó un total de 123 casos de CDIS, puro/con invasión de la base de datos de un hospital de cáncer terciario en el período de febrero de 2007 a febrero de 2018. Se analizaron las características clínicas, radiológicas y patológicas, así como su impacto en el manejo quirúrgico.Resultados: La edad media fue de 50,5 ± 12,4 años. La presentación más común fue masa palpable en el 82,9% de los casos. Se realizó cirugía de mama conservadora con éxito en 15 casos y mastectomía en 108 casos. Se informó de recaída en 11 casos. La tasa de subestimación en la biopsia con aguja fue de 48,9% sin componente invasivo en lesiones malignas diagnosticadas y 19,6% sin diagnóstico de malignidad. Por otra parte, se observó un exceso de tratamiento con relación al procedimiento quirúrgico y las terapias adyuvantes.Conclusiones: La mastectomía sigue siendo el tratamiento quirúrgico más común del CDIS y desafortunadamente no se utiliza aún la biopsia de ganglio linfático centinela. La subestimación del componente invasivo puede ocurrir en al menos el 25% de los pacientes, complejizando el plan de tratamiento. Debe gestionarse el sobretratamiento con cirugía axilar, quimioterapia o radioterapia. (AU)

Introduction Breast carcinoma is the most common malignancy in women worldwide. It is also one of the most frequent causes of brain metastasis (BM). Studies have identified BM as one of the worst prognostic signs. Methods We retrospectively analyzed data from 71 patients with BM from BC with the aim of clarifying the epidemiological criteria and management in our setting. We also aimed to identify predictors of survival and factors affecting the length of the BM-free interval in our group of patients. Results All the patients were female with a mean age at diagnosis of primary cancer of 41.6 years. The most common site of BM was the parietal lobe. The BM-free interval was longer with N1 disease (in comparison to N2 and 3) and in luminal B breast cancer subtype. Survival was shorter in older patients, those with hormone receptor negative and/or HER2-neu positive disease, synchronous BM, primary tumour not removed, soft tissue/non-regional nodes concomitant metastasis, and those who did not receive palliative chemotherapy. Survival tended to be longer in patients with temporal lobe metastasis, but this result was not statistically significant. Conclusion BM is a bad prognostic sign. Large scale prospective studies are needed to further delineate its nature. (AU)
Introducción El carcinoma de mama es la neoplasia maligna más común en las mujeres del mundo. Además, es una de las causas más comunes de metástasis cerebral (MC). Los estudios detectan MC como uno de los peores signos pronósticos. Métodos Analizamos retrospectivamente los datos de 71 pacientes con MC de origen mamario con el objetivo de clarificar los criterios epidemiológicos y el esquema de manejo en nuestra localidad de esta enfermedad, además de detectar predictores de supervivencia y factores que afectan la longitud del intervalo libre de MC en nuestro grupo de pacientes. Resultados Todos los pacientes fueron mujeres con una edad media de diagnóstico de cáncer primario de 41,6 años. El sitio más común de MC fue el lóbulo parietal. El intervalo libre de propagación cerebral fue más largo con la enfermedad N1 (en comparación con N2 y 3) y en el subtipo de cáncer de mama luminal B. La supervivencia fue menor en pacientes mayores, aquellos con receptores hormonales negativos y/o enfermedad HER2-neu positiva, MC sincrónica, tumor primario no extirpado, metástasis concomitantes de tejido blando nodos no regionales y aquellos que no recibieron quimioterapia paliativa. Además, aquellos con metástasis del lóbulo temporal tienden a tener una mejor supervivencia, aunque no alcanzaron significación estadística. Conclusión La MC es un mal signo pronóstico. Se necesitan estudios prospectivos a gran escala para delinear aún más su naturaleza. (AU)

INTRODUCTION: Breast cancer is a common worldwide healthcare problem. Identifying metastatic lesions is crucial for adequate staging. However, there is no standardized metastatic work-up in early-stage breast cancer patients. MATERIALS AND METHODS: We retrospectively analyzed data from patients treated in a tertiary hospital for clinical early-stage breast cancer, to assess the value of alkaline phosphatase (ALP) as a predictor of metastasis and as a prognostic factor. RESULTS: We detected a significant correlation between ALP and metastasis at diagnosis, and found that ALP is both a sensitive and specific marker in screening for metastasis in early-stage breast cancer. CONCLUSION: ALP is a useful marker of metastasis at diagnosis. Further prospective studies are needed to delineate the incidence and impact of missed metastatic patients if metastatic work-up is omitted
INTRODUCCIÓN: El cáncer de mama es un problema de salud común en todo el mundo. La identificación de lesiones metastásicas es crucial para una estadificación adecuada. Sin embargo, no hay un estudio metastásico estandarizado en pacientes de cáncer de mama precoz. MATERIALES Y MÉTODOS: Se analizaron retrospectivamente datos de pacientes tratados en un hospital terciario por cáncer de mama en estadio clínico temprano, para evaluar el valor de la fosfatasa alcalina (ALP) como predictor de metástasis y como factor pronóstico. RESULTADOS: Los autores detectaron correlación significativa entre ALP y metástasis en el momento del diagnóstico, y demostraron que ALP es un marcador sensible y específico en la detección de metástasis en cáncer de mama precoz. CONCLUSIÓN: La ALP es útil en el diagnóstico de metástasis en el momento de la valoración. Se necesitan más estudios prospectivos para delinear la incidencia y el impacto de los pacientes metastásicos perdidos, si se omite el análisis metastásico

ABSTRACT Introduction: Colorectal cancer is the 4th commonest cancer in the world. Studies had shown different tumor behavior depending on the site, pathology and stage. However the characters of Egyptian colon cancer patients are not well addressed. Method: Computerized registry of a tertiary cancer hospital in Egypt was searched for colon cancer cases. Demographic, pathologic and treatment data were collected and analyzed using SPSS program. Results: About 360 colon cancer patients attended our center in the last 12 years. Tumor characters showed great diverse from that of developed countries, with especially different prognosis and survival. Conclusion: Egyptians have unique tumor characters and behavior, and different compliance with treatment regimens. Multicenter prospective studies, as well as evolving Egyptian treatment guidelines are needed to address this.
RESUMO Introdução: Câncer colorretal é a quarta neoplasia mais comum a nível mundial. Estudos demonstraram diferentes comportamentos do tumor, dependendo do local, da patologia e do estágio. Contudo, ainda não estão devidamente definidas as características dos pacientes egípcios com câncer de cólon. Métodos: Foi realizada pesquisa no registro computadorizado de um hospital terciário para pacientes com câncer, à busca de casos de câncer de cólon. Foi feita coleta de dados demográficos, patológicos e terapêuticos. Tais dados foram então submetidos à análise com o programa SPSS. Resultados: Nos últimos 12 anos, cerca de 360 pacientes portadores de câncer de cólon foram atendidos em nosso Centro. As características dos tumores demonstraram grandes diferenças em comparação com os achados de países desenvolvidos e, em especial, com relação ao prognóstico e à sobrevida. Conclusão: Os egípcios exibem características e comportamentos singulares com relação aos tumores, além de diferentes graus de cooperação com os regimes terapêuticos. Para que tais aspectos sejam sanados, há necessidade de mais estudos prospectivos multicêntricos, bem como de um aprimoramento das diretrizes terapêuticas para os egípcios.
