Pattern of malignant tumors observed in a university hospital: a retrospective analysis

A retrospective analysis of all malignant tumors observed in adults over a four-years period is presented. From January 1, 1989 to December 31, 1992, 2623 patients were coded by the Indexing and Coding Unit of Medical Records, The Aga Khan University Hospital to have cancer. Data presented reflect the relative frequency of different cancers seen at a single institution. Lung cancer was the commonest tumor observed in males. It was closely followed by head and neck cancer and lymphoma. In females, breast was the commonest cancer followed by ovarian and gallbladder. In comparison to the Western figures, an increased frequency of lymphomas and head and neck cancers was observed in males. Prostatic and colorectal cancers were less frequently observed. In females, gallbladder cancer is strikingly more frequent. Cervical cancer was less commonly observed as compared to the other developing countries and uterine cancer was infrequent in comparison to the Western countries. These data carry important implications for future health planning.
