First data from a population based cancer registry in Ethiopia

Background: The Addis Ababa City Cancer Registry, established in September 2011, is the only population-based cancer registry in Ethiopia, covering a catchment population of just over three million habitants. Herein, we report incidence data based on the first two years of registration, 2012-2013. Methods: Newly-diagnosed cancer cases in the capital city were actively collected from 22 hospitals, clinics, and diagnostic facilities. Results: During 2012-2013, a total of 4139 newly diagnosed cases were recorded, with the majority (67%) occurring in females. Cancers of the breast (31.5%) and cervix (14.1%) were the two most common cancers among females, while colorectal cancers (10.6%) and non-Hodgkin lymphomas (10.2%) were the most common cancers among males. The average annual age-standardized rate for all sites 2012-13 were 136.2 (per 100,000) and 70.7 in females and males, respectively. Female age-standardized rates were 40.6 for breast cancer and 21.5 for cervix, while equivalent rates in males were 7.6 per 100,000 for colorectal cancer and 6.8 per 100,000 for non-Hodgkin lymphoma. Conclusion: In general, these incidence patterns were similar to those reported in neighboring countries, which suggests that the majority of cancer cases occurring in Addis Ababa are captured within this starting phase of the registry. However, our finding of colorectal cancer as the most commonly-diagnosed cancer in males is novel and requires further investigation.
