RESUMO
Abstract Introduction: Among the sub-types of lymphoma, mantle cell lymphoma, or what was previously known as intermediate lymphocytic lymphoma, accounts for 3-10% of B-cell non-Hodgkin lymphomas. Treatment is directed according to the patient's classification, age, functional status and comorbidities, and is directly related to the ability to receive intensive treatment or transplantation. It is important to homogenize treatments to offer the best alternatives in the Colombian context, as there are different diagnostic and therapeutic options today, most of which are financed by the Colombian healthcare system. Objective: To structure a series of considerations for the diagnosis and treatment of MCL within the Colombian context. Methods: A formal, mixed (Delphi/nominal) expert consensus was developed. The options for each question were scored in two masked rounds and an open nominal session. The information was consolidated in Excel and analyzed using STATA 13. Results: 25 considerations were developed for the diagnosis and treatment of MCL. Twenty-two specialists participated: 16 hematologists and hematologist-oncologists, four hematopathologists, one radiation therapist and one nuclear medicine specialist from Bogotá, Medellín and Cali, with an average of 10.5 years' of practical experience and who were members of the Asociación Colombiana de Hematología y Oncología [Colombian Association of Hematology and Oncology]. Conclusions: The consensus established 26 considerations for the diagnosis and treatment of MCL, according to the Colombian context, aimed at healthcare professionals with a direct relationship with this disease. It is expected that clinical management will be homogenized by a consideration of this consensus and the referenced literature. (Acta Med Colomb 2022; 48. DOI:https://doi.org/10.36104/amc.2023.2606).
Resumen Introducción: Dentro de los subtipos de linfoma, el linfoma de células del manto o anteriormente denominado linfoma linfocítico intermedio corresponde a 3-10% de los linfoma no Hodgkin de células B. El tratamiento se enfoca según la clasificación del paciente, edad, estado funcional y comorbilidades, lo cual está directamente relacionado con la capacidad de recibir un tratamiento intensivo o trasplante. Es importante homogeneizar conductas con el fin de ofrecer las mejores alternativas bajo el contexto colombiano, pues actualmente existen diferentes opciones diagnósticas y terapéuticas, financiadas en su mayoría por el sistema de salud colombiano. Objetivo: Estructurar una serie de consideraciones para el diagnóstico y tratamiento para LCM, en el contexto colombiano. Métodos: Se llevó a cabo un consenso formal de expertos, tipo mixto (Delphi/ Nominal). Se calificaron las opciones de cada pregunta en dos rondas enmascaradas y una sesión abierta nominal. La información fue consolidada en Excel y analizada en STATA 13. Resultados: Se elaboraron 25 consideraciones para el diagnóstico y tratamiento de LCM. Participaron 22 médicos especialistas: 16 hematólogos y hemato-oncólogos, cuatro hemato-patólogos, un radioterapeuta y un especialista en medicina nuclear de Bogotá, Medellín y Cali, con experticia en la práctica de 10.5 años en promedio y quienes forman parte de la Asociación Colombiana de Hematología y Oncología. Conclusiones: El consenso definió 26 consideraciones para el diagnóstico y tratamiento de LCM, según el contexto colombiano, dirigidas a profesionales de la salud con relación directa a esta patología. Se espera homogeneizar las conductas clínicas teniendo en cuenta este consenso y la literatura referida. (Acta Med Colomb 2022; 48. DOI:https://doi.org/10.36104/amc.2023.2606).
RESUMO
To describe the population with early malignant melanoma, we performed a cohort study on the basis of the Epidemiological Registry of Malignant Melanoma in Colombia-Asociacion Colombiana de Hematologia y Oncologia. From January 2011 until December 2021, 759 patients were included; the average age was 66 years, 57% were women, acral lentiginous histology was found in 27.8% of patients, and the median follow-up was 36.5 months. The prognostic factors for overall survival in our population are Eastern Cooperative Oncology Group 3-4 (hazard ratio [HR], 13.8), stage III (HR, 5.07), received radiotherapy (HR, 3.38), ulceration on histology (HR, 2.68), chronic sun exposure (HR, 2.3), low income (HR, 2.04), previous local surgery (HR, 0.27), and have received adjuvant treatment (HR, 0.41).
