          Abstract

          RESUMEN Introducción: El trasplante autólogo de progenitores hematopoyéticos es una terapéutica aplicable en determinadas situaciones a pacientes con Linfoma de Hodgkin. Objetivo: Evaluar la influencia de factores pronósticos seleccionados en los resultados del trasplante autólogo de progenitores hematopoyéticos en pacientes con Linfoma de Hodgkin. Métodos: Se realizó un estudio retrospectivo de 57 pacientes con diagnóstico de Linfoma de Hodgkin trasplantados en el Hospital Clínico Quirúrgico “Hermanos Ameijeiras” entre 1991 y 2018. La influencia de varios factores desfavorables fue evaluada según sobrevida libre de enfermedad a los cinco años de forma univariada y multivariada. Resultados: Se comprobó una sobrevida libre de enfermedad menor para todos los grupos con las categorías desfavorables. El análisis univariado indicó que el haber recibido tres o más líneas de tratamiento previas, aumentó como promedio 3,48 veces la probabilidad de recaída. En la evaluación múltiple, aumentó de forma significativa la probabilidad de recaída la existencia de enfermedad activa al momento del trasplante (p= 0,023) y el no recibir radioterapia en el tratamiento acondicionante (p= 0,010). Conclusiones: Se demostró la importancia de conocer los factores desfavorables. Notable importancia tuvo evitar enfermedad activa al trasplante y realizar una correcta evaluación de riesgos y beneficios en cuanto a la posible inclusión de la radioterapia en el tratamiento acondicionante.

          ABSTRACT Introduction: Autologous hematopoietic stem cell transplantation is a therapy used in certain situations to patients with Hodgkin's Lymphoma. Objective: To evaluate the influence of selected prognostic factors on the results of autologous hematopoietic stem cell transplantation in patients with Hodgkin's Lymphoma. Methods: A retrospective study of 57 patients with a diagnosis of Hodgkin Lymphoma transplanted at Hermanos Ameijeiras Clinical Surgical Hospital from 1991 to 2018 was carried out. The influence of several unfavorable factors was evaluated according to univariate and multivariate disease-free survival at five years. Results: A lower disease-free survival was found for all groups with unfavorable categories. Univariate analysis indicated that receiving three or more previous lines of treatment increased the probability of relapse on average 3.48 times. In the multiple evaluation, the probability of relapse was significantly increased by the existence of active disease at the time of transplantation (p = 0.023) and by not receiving radiotherapy in the conditioning treatment (p = 0.010). Conclusions: The importance of knowing the unfavorable factors was established. It was of noteworthy importance to avoid active disease at transplantation and to carry out a correct evaluation of risks and benefits regarding the possible inclusion of radiotherapy in the conditioning treatment.

          The 2016 revision of the World Health Organization classification of lymphoid neoplasms.

          A revision of the nearly 8-year-old World Health Organization classification of the lymphoid neoplasms and the accompanying monograph is being published. It reflects a consensus among hematopathologists, geneticists, and clinicians regarding both updates to current entities as well as the addition of a limited number of new provisional entities. The revision clarifies the diagnosis and management of lesions at the very early stages of lymphomagenesis, refines the diagnostic criteria for some entities, details the expanding genetic/molecular landscape of numerous lymphoid neoplasms and their clinical correlates, and refers to investigations leading to more targeted therapeutic strategies. The major changes are reviewed with an emphasis on the most important advances in our understanding that impact our diagnostic approach, clinical expectations, and therapeutic strategies for the lymphoid neoplasms.

            Understanding survival analysis: Kaplan-Meier estimate

            Kaplan-Meier estimate is one of the best options to be used to measure the fraction of subjects living for a certain amount of time after treatment. In clinical trials or community trials, the effect of an intervention is assessed by measuring the number of subjects survived or saved after that intervention over a period of time. The time starting from a defined point to the occurrence of a given event, for example death is called as survival time and the analysis of group data as survival analysis. This can be affected by subjects under study that are uncooperative and refused to be remained in the study or when some of the subjects may not experience the event or death before the end of the study, although they would have experienced or died if observation continued, or we lose touch with them midway in the study. We label these situations as censored observations. The Kaplan-Meier estimate is the simplest way of computing the survival over time in spite of all these difficulties associated with subjects or situations. The survival curve can be created assuming various situations. It involves computing of probabilities of occurrence of event at a certain point of time and multiplying these successive probabilities by any earlier computed probabilities to get the final estimate. This can be calculated for two groups of subjects and also their statistical difference in the survivals. This can be used in Ayurveda research when they are comparing two drugs and looking for survival of subjects.
