Section snippets
Material and methods
Data for this analysis were obtained from the Singapore Cancer Registry, a population-based cancer registry covering the entire resident population of Singapore. Singapore is a small island republic with a resident population of 2.7 million in 1990. Seventy-eight percent are ethnic Chinese, 14% Malay, and the remaining of Indian or other origin.8 During 1968 to 1992, there were a total of 3768 invasive cervical cancer patients registered, after exclusion of in situ cases. Among these, 38 cases
Results
The survival of cervical cancer patients improved over the entire study period of 1968 through 1992 regardless of the clinical stage of disease at presentation (Figs 1 and 2).The overall 5-year age-standardized relative survival (ASRS) for all patients was 65% in 1988-1992 compared with 45% in 1968-1972. The improvement was
Comment
This is the first population-based study describing a unique changing pattern of survival experience among cervical cancer patients in Singapore. Population-based survival estimates are useful for evaluating the effectiveness of health services and availability of effective cancer treatment in a population. Such investigations are based on more heterogeneous groups and differ substantially from those based on clinical series in which patients undergoing comparative treatment regimes are highly
