Increased incidence of prostate cancer in Nigerians

An increased incidence of prostate cancer among African-American men (now t he second most common cause of cancer death) has been attributed mainly to the introduction of screening techniques, which have enabled earlier diagno sis of patients. This study reviewed male cancer patients recorded in a Nig erian cancer registry to assess the current trends in prostate cancer in Ni geria. For comparison, data were broken into two groups: 1980-1988 and 1989 -1996. Only the top 10 cancers occurring in both periods were considered in itially in this report. For emphasis, an analysis of adult male cancers was done per decade since 1960. Results show that prostate cancer has become the number one cancer in Niger ian men and constitutes 11% of all male cancers. The median age of patients was 67.5 years (variance 5.6), and the mean age was 71.4 years (variance 1 4.3). These results indicate that despite the absence of screening programs in Nigeria, the number of prostate cancer cases has increased. The known r isk Factors probably contribute to a varying degree among Nigerians, who ar e generally of average build or in the low-normal range for body mass index . Moreover, the role of genetics cannot be underplayed. Given its biologica l characteristics, more cases of prostate cancer probably would be recorded among this population if screening were undertaken.
