ABSTRACT
Objetivo: Evaluar el valor pronostico del índice linfocito monocito (ILM) en la sobrevida global de los pacientes con Linfoma de células grandes B difuso (LCGBD) del Hospital Edgardo Rebagliati Martins. Métodos: Estudio longitudinal retrospectivo. Se incluyó a los casos de LCGBD diagnosticados en el Hospital Nacional Edgardo Rebagliati Martins durante el período 2010-2017. No se realizó muestreo, se trabajó con la totalidad de la población que cumplió con los criterios de selección por ser esta pequeña y accesible. Se revisó las historias clínicas de los pacientes obteniéndose información del tiempo en meses de supervivencia, del ILM así como de variables sociodemográficas, clínicas y de laboratorio. Resultados: Se incluyó en el análisis a 121 pacientes con LCGBD; de ellos, el 57% eran de sexo femenino y 66.1% eran mayores de 60 años. De acuerdo al Status Zubrod, el 66,5% correspondieron al grado de mejor pronóstico y el 59.5% presento sintomas B asociados. Cerca del 60% fueron diagnosticados en estadios I y II y el 57% presento compromiso extraganglionar. El análisis bivariado con el modelo de riesgos proporcionales de Cox mostró que el ILM<2 constituyó un predictor de la supervivencia global del LCGBD (p=0,011) estimándose un HR=2.2 (IC 95%: 1.2-4.1); asimismo, un ILM< 1,7 también constituyó predictor (p=0,009) estimándose un HR=2.2 (IC 95%: 1.2-4.1). El ILM<2,7 no constituyó predictor de la supervivencia global. Conclusión: El ILM podría utilizarse como un índice pronóstico debido a que constituye un predictor de la supervivencia global de los pacientes con LCGBD del Hospital Nacional Edgardo Rebagliati Martins.
Objetive: To evaluate the prognostic value of the monocyte lymphocyte index (ILM) in the overall survival of patients with diffuse large B-cell lymphoma (LCGBD) of the Edgardo Rebagliati Martins Hospital. Methods: Retrospective longitudinal study. We included cases of LCGBD diagnosed in the National Hospital Edgardo Rebagliati Martins during the period 2010-2017. No sampling was done, we worked with the entire population that met the selection criteria because it is small and accessible. The patients' clinical histories were reviewed, obtaining information about the time in months of survival, ILM, as well as sociodemographic, clinical and laboratory variables. Results: 121 patients with LCGBD were included in the analysis; of them, 57% were female and 66.1% were older than 60 years. According to the Zubrod Status, 66.5% corresponded to the degree of better prognosis and 59.5% presented associated B symptoms. About 60% were diagnosed in stages I and II and 57% presented extranodal involvement. The bivariate analysis with the Cox proportional hazards model showed that the ILM <2 constituted a predictor of the overall survival of the LCGBD (p = 0.011), estimating HR = 2.2 (95% CI: 1.2-4.1); likewise, an ILM <1.7 was also a predictor (p = 0.009) with an estimated HR = 2.2 (95% CI: 1.2-4.1). ILM <2.7 was not a predictor of overall survival.. Conclusion: The ILM could be used as a prognostic index because it is a predictor of the overall survival of patients with LCGBD of the Edgardo Rebagliati Martins National Hospital.

ABSTRACT
PURPOSE: Peripheral T-cell lymphoma (PTCL) derived from mature T cells forms morphologically diverse group of non-Hodgkin's lymphomas and the clinicopathologic features remain to be debated. In order to elucidate the specific characteristics of PTCL, comparison with a group of diffuse B-cell lymphomas (DBCL) was done. MATERIALS AND METHODS: Between Dec. 1989 and Feb. 1993, clinical data of 67 cases of intermediate or high grade NHL identified as T-cell or B-cell origin by immunophenotyping was reviewed. RESULTS: There were 30 cases of PTCL and 37 cases of DBCL. PTCL had more advanced stage and B symptoms at diagnosis. Frequent sites of extranodal involvement were bone marrow, nasal cavity/paranasal sinus, and skin in PTCL and gastrointestinal tract in DBCL. Based on NCI Working Formulation, 40% of PTCL and 14% of DBCL were high grade. Patients with DBCL had a better 3-year overall survival rate (67% vs 47%), however, there was no difference in complete remission rate and disease-free survival rate between two groups with intensive treatment. A subgroup of PTCL patients who had died earlier was found to have more advanced stage and poor performance status. CONCLUSION: Although patients with PTCL had worse survival in advanced stage, the outcome of patients with PTCL who received intensive treatment was comparable to that of DBCL.
