Gastric cancer is the second leading cause of malignant tumours in Mexico.
The distribution of the histological types of this tumour has not been estimated from a population-based representative sample.
The histological types of gastric cancer according to the Lauren classification and selected socio-demographic characteristics for 220 patients from different socioeconomic levels are reported.
The study population represents 66% of all new gastric cancer cases during 1989-1990 reported to the Mexico City Cancer Registry.
The patients attended four public hospitals, seven social security hospitals and four private hospitals in Mexico City.
A second histological diagnosis was performed by one pathologist.
No specific histological type of gastric cancer predominated since the estimated distribution for intestinal gastric cancer was 44.5%, for diffuse gastric cancer 43.2% (and the remaining 12.3% corresponded to indeterminate tumours).
The distribution of intestinal and diffuse gastric cancer did not vary significantly according to socioeconomic level or medical care unit and it showed a clear relationship with gender, the intestinal type of gastric cancer being more common among males. (...)
