The incidence of prostate cancer-trends in two ethnic groups in Trinidad: a nine year study - abstract

ABSTRACT

Data on prostate cancer patients were obtained from the Pathology Department, General Hospital, San Fernando (before 1993) and, after 1993, prospectively collected for all admissions to that hospital for all patients with prostate cancer. Additonal data was collected from the hospital theatre registers and medical records. 365 prostate patients' data over the nine year period 1987-1995 were analysed for tends in the disease. In the population served by the hospital there are equal numbers of East Indians and Africans in the age range > 60 years. There was a rapid rise in the incidence of prostate cancer in males > 60 years starting in 1993, when PSA became widely available. This rise was maintained and seen mainly in the African population though there was a lesser rise among the East Indians. In most years, prostate cancer was more frequent in African than East Indian men. These data emphasize the value of PSA in detecting prostate cancer in both races but there is need for more education and systematic screening programmes to detect the asymptomatic male who can be offered curative therapy. The significantly higher frequency of prostate cancer in Africans (87.2 percent) than East Indians (12.8 percent) may be associated with differences with genetic and dietary factors and not with environment which is the same for both races.
