Pattern of malignant diseases at the University of Benin Teaching Hospital.

This study was designed to evaluate the pattern of malignant diseases seen at the University of Benin Teaching Hospital over a 20-year period (January 1980-December 1999). A total of 2258 histologically confirmed malignant diseases were seen with the predominant tumours comprising carcinoma of the cervix (20.59%), breast (18.25%), prostate (7.13%), endometrium (6.47%) and colon and rectum (5.71%). We believe that the figure reported here represents an underestimate of the frequency of malignant tumours seen in the hospital and recommend the establishment of hospital- and population-based cancer registries to ensure proper documentation of malignant diseases within the region.
