Objetivo: Describir la asociación entre la mortalidad por adenocarcinoma gástrico y el tipo de seguro de salud en el Perú. Métodos: Estudio de cohorte retrospectivo realizado en un hospital público de referencia en Lima, Perú. La variable resultado fue el tiempo hasta evento, definida como la cantidad de días transcurridos entre la fecha de diagnós-tico y la fecha de muerte o fecha de censura; y la variable de exposición fue el tipo de seguro de salud del paciente. Se usó la regresión de Cox para evaluar la asociación de interés, reportándose Hazard Ratios (HR) e intervalos de confianza al 95% (IC95%). Resultados: Se incluyeron a 429 pacientes, edad promedio de 57,6 años (DE 13,8), y 256 pacientes mujeres (48,4%). De acuerdo al tipo de seguro de salud, 311 pacientes (77,7%) tuvieron Seguro Integral de salud (SIS), brindado por el Ministerio de Salud; 63 (11,9%), no tuviero...

Testicular cancer is the most common solid tumor in men between ages 15 and 29. It can metastasize through the hematogenous or lymphatic routes to different organs such as the lung and liver (common) and the stomach (uncommon). We present thecase of a 30-year-old male patient with upper gastrointestinal bleeding due to two ulcers in the stomach body with histology of unspecified small-cell malignant neoplasm. CT scans showed a right testicular tumor with secondary implants in the brain, lung, liver and spleen. β-HCG (35,5354 mIU/mL), AFP (500 ng/mL) and LDH (1,669 IU/L) tests were conducted. A right radicalorchiectomy was performed. It is concluded that this was a clinical stage IIIC primary germ cell tumor of the right testis due to liver, spleen, lung, gastric and brain metastases.

Gastric cancer ranks fifth in both incidence and mortality worldwide, according to the report fromthe Global Cancer Observatory (Globocan) as of 2022 (1). When discussing the global gastric cancerreport, it is assumed that it refers to adenocarcinoma. However, it should be pointed out that themost frequent histological types of gastric cancer are adenocarcinoma and lymphoma, the formerbeing the most frequent on average, accounting for over 95 % of all gastric neoplasms (2). In Peru, theLima Metropolitan Cancer Registry ranked gastric cancer as the third most frequent and the leadingcause of mortality for both sexes (3). On the other hand, the synchronous or metachronous diagnosisof these types of gastric cancer, such as adenocarcinoma and lymphoma, is rare. Metachronouscancer, or second primary cancer, is defined as a new tumor that occurs more than six months afterthe diagnosis of the f...
