Background: Gastrointestinal tumors account for a large proportion of all neoplasms. Colorectal cancer ranks second and stomach cancer ranks fourth amongst the most common tumors of the world, according to the World Cancer Report of 2000. Aims: The present study was undertaken with a view 1) To determine the frequency of GIT tumors with respect to age, sex and site of lesion in our institute. 2) To classify the GIT tumor according to WHO classification. Material and Methods: This was a prospective study over three years period. Gross and histopathological examination of the specimens was done, for assessing appearance and extent of lesion. Stains used were routine hematoxylin and eosin stain. Special stains such as Periodic acid Schiff (PAS), Alcian blue, Mucicarmine were done wherever required. The clinicopathological data was analyzed and observations were noted. Results: Of 129 cases of GI tumours, 98% were malignant and 1.6% was benign. GI malignancies had a peak in 5160 years. M: F ratio was 1.1:1. Colorectal cancers occurred most commonly followed by oesophagus, stomach and small intestine in descending order. Conclusion: There is a need to conduct detailed studies before these societies are transformed into westernlike environments. Otherwise we may miss an unique opportunity to understand the factors that could prevent many cancers in the world.
