Cancer survival in Kampala, Uganda, 1993-1997.

Abstract

The Kampala cancer registry was established in 1954 as a population-based cancer registry, and registration of cases is done by active methods. The registry contributed data on survival for 15 cancer sites or types registered in 1993-1997. For Kaposi sarcoma, only a random sample of the total incident cases was provided for survival study. Follow-up has been carried out predominantly by active methods, with median follow-up ranging from 4-26 months. The proportion with histologically verified diagnosis for various cancers ranged between 36-83%; death certificate only (DCO) cases were negligible; 58-92% of total registered cases were included for survival analysis. Complete follow-up at five years ranged between 47-87% for different cancers. Five-year age-standardized relative survival rates for selected cancers were Kaposi sarcoma (22%), cervix (19%), oesophagus (5%), non-Hodgkin lymphoma (26%), breast (36%) and prostate (46%). None survived beyond 5 years for cancers of the stomach and lung. Five-year relative survival by age group was fluctuating with no definite pattern or trend emerging and no survivors in many age intervals.
