In 2000, Magoha published data on 59 patients diagnosed with locally advanced or metastatic prostate cancer at 3 hospitals in Nairobi. Fifteen patients had poorly differentiated cancers (Gleason score = 8-10); another 15 patients had moderately differentiated cancers (Gleason score = 6); and 29 patients had well differentiated cancers (Gleason score = 2-4). Survival of the 15 poorly differentiated patients was very poor, with all patients dying within 12 months of diagnosis, despite treatment with orchiectomy and bicalutamide. Only 22/59 patients were alive 48 months after diagnosis, regardless of treatment, and 20/22 had well-differentiated cancers (Gleason score ≤ 4).
The GLOBOCAN 2002 database (compiled by Ferlay et al. for the International Agency for Research on Cancer) provides the following data for prostate cancer in Kenya:
- Estimated number of new cases per year: 1,007
- Estimated age-standardized rate of new cases per year: 16.6/100,000
- Estimated number of deaths per year: 850
- Estimated age-standardized number of deaths per year: 14.1/100,000
- Estimated 1-year prevalence: 790
- Estimated 5-year prevalence: 2,631
The WHO Impact of Cancer in Your Country data tables provide the following data for prostate cancer in Kenya:
- Estimated age-standardized incidence (in 2002): 34/100,000
- Estimated age-standardized death rate (in 2005): 23/100,000
In 2007, Wasike and Magoha reported on 65 patients diagnosed with prostate cancer at the Kenyatta National Hospital in Nairobi between November 1998 and October 1999. The crude hospital incidence was 76.5/100,000 patients , and the crude hospital death rate was 5.8/100,000. The vast majority of these patients (87.5 percent) presented late in the disease course, with clinical stage III (C) or IV (D) prostate cancer.
If you know of additional sources of specific or current information about the incidence, prevalence and mortality of prostate cancer in Kenya, we would be interested in learning about them. Please post such information in the comment box below.
