Objetivo: Estimar la probabilidad de recurrencia en pacientes con cáncer de lengua según la edad, el estado ganglionar patológico y el tipo de tratamiento de los pacientes considerando la muerte antes de la recurrencia como evento competitivo. Material y métodos: Serie de casos retrospectiva de 290 pacientes con cáncer de lengua, con tratamiento en el INEN, entre los años 1977 y 2000. Se excluyeron del estudio 29 pacientes tratados solo con radioterapia. De los 261 pacientes, 31 solo tuvieron tratamiento del tumor primario. Resultados: La recurrencia fue 36,8%, la recurrencia local fue la más frecuente. La incidencia acumulada de la recurrencia a los 5 años, con el método de Kaplan Meier, se estimó en 44,7%, y según el análisis de riesgos competitivos en 42,4%. En el análisis univariado considerando riesgos competitivos, las incidencias acumuladas fueron: 56,8 y 38,9% en pac...

Objective. The main of this research was to evaluate the clinicopathological characteristics of diffuse large B-cell lymphoma, no other specification (DLBCL, NOS) in a cohort of Peruvian patients diagnosed between 2005 and 2009. Methods. Seventy-two cases diagnosed with DLBCL, NOS, were studied at the National Institute of Neoplastic Diseases. Clinicopathological characteristics were evaluated and overall survival (OS) and other clinical parameters were compared according to cell of origin, Epstein-Barr virus (EBV) infection, and immunohistochemical (IHC) expression of MYC and BCL2. Results. There were 54 % women and 46 % men, with an average age of 65 years. 76 % were nodal, the majority cervical, and 24 % extranodal, with the stomach being the most affected site. The most frequent stages were II (35 %) and III (29 %), the majority with medium-high and high IPI. Histologically, almost a...

Seventy-two cases with a diagnosis of LCBGD, NOS, were studied at the INEN. Clinicopathological characteristics, overall survival (OS) and other clinical parameters were evaluated according to origin cell, Epstein-Barr virus infection (EBER), and the immunohistochemical expression (IHC) of MYC and BCL2. Results. There were 54% women and 46% men, with an average age of 65 years. 76% were ganglionic, the majority cervical location and 24% extranodal, the stomach being the most affected. The most frequent stages were II (35%) and III (29%), the majority with medium-high and high IPI. Histologically, almost all cases had centroblastic and immunoblastic morphology. There was a similar proportion of cases with germinal...

Aim: Describe and analyze the safety of the “Enhanced Recovery After Surgery” (ERAS) protocol in elective procedures for colorectal cancer. Materials and Methods: Observational study of 272 patients with colorectal cancer who underwent elective surgery from January 2019 to September 2020 at the “Instituto Nacional de Enfermedades Neoplásicas”, Peru, were retrospectively collected. U Mann-Whitney test, Pearson chi-square test and odds ratios (OR) were used for statistical analysis. Results: 90 patients were included in the ERAS program with a median postoperative hospital stay of 3 days (range 3-19). Laparoscopic surgery was performed in 53% of the patients with significantly shorter postoperative hospital stay in comparison with the patients who had open surgery (p=0,035). Oral food intake less than 24 hours postoperatively was 91%, and early mobilization in 89% of the cases. Th...
