Cancer of the alimentary tract in a West Indian population: a Trinidad study.

630 cases of primary malignant tumours of the alimentary tract in a West Indian population in Trinidad were analysed for frequency, age, sex and clinicopathological presentations. In a population predominantly Negro and Indian in origin, alimentary tract cancers comprised 13% of the total malignancies. The alimentary tract tumours were commonest in the sixth and seventh decades; there was a slight male preponderance. Stomach and colon were the common sites of malignancy. The clinical and pathological features were not different from other reported series.
