Background: Cancer has become a global public health challenge and the number one cause of premature death. The incidence is increasing globally and more rapidly in low and middle-income countries despite the gross under-registration and challenges in diagnosis. Data about Uganda is mostly from the Mulago cancer registry which may not entirely represent other parts of the country. This study presents the trends of cancer incidence for Southwestern Uganda in a decade (2012 to 2021).
Method: We did a review of records at the Mbarara University histopathology laboratory and Mbarara Regional Referral Oncology Clinics from January 2012 to December 2021 for cancer diagnoses. Records missing patients' age or sex were excluded.
Results: We registered 4197 incident cancers, 51.8% were among males, and 10.7% were among children (0-18 years). The median age was 52 years and the interquartile range was 35-67 years. The most commonly diagnosed cancers were prostate cancer (13.46%), ocular surface carcinoma (11.03%), cervical cancer (10.55%), head and neck cancers (7.31%), esophageal carcinoma (6.79%), lymphomas (5.36%), retinoblastoma (5.31%), and breast cancer (5.00%) in descending order. Retinoblastoma was the most common cancer among children.
Conclusion: The cancer pattern in Southwestern Uganda has changed and the numbers diagnosed each year are increasing. Prostate cancer is the most common diagnosed cancer overall, and the commonest cancer among men. Among women, cervical cancer is the most common cancer, followed by ocular surface carcinoma, and breast cancer. Retinoblastoma is the most common cancer among children. The trend of Kaposi sarcoma has plummeted together with ocular surface carcinomas. The cancer trends seem to be influenced by the presence of diagnostic and treatment expertise in the region.
