RESUMO
OBJECTIVE: Determine the survival rate of patients diagnosed with stomach cancer in 2009-2010 in Peru. METHODS: A retrospective cohort study was conducted of patients diagnosed with stomach cancer registered in the National Epidemiological Surveillance System (SNVE) of the Directorate General of Epidemiology (DGE) and the Register of Vital Statistics (RHV) of the General Office of Statistics and Information (OGEI) for the years 2009-2010. RESULTS: 3 568 patients of the SNVE were included; 51.5% were men and 48.5% were women; the average age was 63.9 years; 60.07% were 60 years old or older. It was found that 33.6% had intestinal type adenocarcinoma, 18.7% had diffuse type carcinoma, and 4.1% had primary gastric lymphoma. The overall survival rate was 29.7 ± 0.8 months and was better for those under 60 years (P = 0.034), for women (P = 0.014) and for intestinal type adenocarcinoma (P< 0.001). There was no difference (P = 0.713) between the survival rate of gastric lymphomas and adenocarcinomas. In order to evaluate mortality, 6 069 patient records from the RHV were included; national mortality was 10.3 per 100 000 population; the regions with the highest mortality were Huánuco, Huancavelica, and Junín. CONCLUSIONS: The general survival rate was 29.7 ± 0.8 months; women, those under 60 years, and patients with intestinal type adenocarcinoma had better survival rates. The highest mortality from stomach cancer is concentrated in the poorest regions of Peru, where it is probable that living conditions facilitate the high communicability of Helicobacter pylori.

OBJETIVO: Determinar la sobrevida de pacientes con diagnóstico de cáncer gástrico en 2009-2010 en el Perú. MÉTODOS: Se realizó un estudio de tipo cohorte retrospectivo de pacientes con diagnóstico de cáncer gástrico registrados en el Sistema Nacional de Vigilancia Epidemiológica (SNVE) de la Dirección General de Epidemiología (DGE) y del Registro de Hechos Vitales (RHV) de la Oficina General de Estadística e Informática (OGEI) para los años 2009-2010. RESULTADOS: Se incluyeron 3 568 pacientes del SNVE, 51,5% eran hombres y 48,5% eran mujeres; la media de edad fue 63,9 años, 60,07% tenían 60 años o más. Se halló que 33,6% tenía adenocarcinoma de tipo intestinal, 18,7% tenía carcinoma de tipo difuso y 4,1% tenía linfoma gástrico primario. La sobrevida global fue de 29,7 ± 0,8 meses y fue mejor para los menores de 60 años (P = 0,034), para las mujeres (P = 0,014) y para el adenocarcinoma de tipo intestinal (P < 0,001). No hubo diferencias (P = 0,713) entre la sobrevida de los pacientes con linfoma gástrico y aquellos con adenocarcinoma. Para evaluar la tasa de mortalidad se incluyeron 6 069 registros de pacientes del RHV, la tasa de mortalidad nacional fue de 10,3 por cada 100 000 habitantes y las regiones con mayor mortalidad fueron Huánuco, Huancavelica y Junín. CONCLUSIONES: La sobrevida general fue de 29,7 ± 0,8 meses, las mujeres, los menores de 60 años y los pacientes con adenocarcinoma de tipo intestinal tienen mejor sobrevida. La mayor mortalidad por cáncer gástrico se concentra en las regiones más pobres del Perú, donde es probable que las condiciones de vida faciliten la alta transmisibilidad de Helicobacter pylori.
