Gastrointestinal malignancies in a young tropical African population.

The records of 695 patients with confirmed gastroenterological malignancies over a 10 year period (January 1976-December 1985) were analysed. Of these, 264 patients (37.98%) were below the age of 40 years. Primary liver cell carcinoma was the commonest malignancy while gallbladder and oropharyngeal cancers were the least common. Most of the patients (66.3%) were in their fourth decade. The prognosis was poor as most of the patients presented late.
