The Emerging Pattern in Prostate Cancer in Zimbabwe
Abstract:
Background: Prostate cancer has become the
leading cancer and cause of death in Zimbabwean men. The number of confirmed
prostate cancer cases has been on the increase since the turn of the century.
Considering this trend a retrospective cross sectional study was carried out to
determine the pattern of the disease and the role played by the prostate
specific antigen in its detection.
Objectives: The aim of the study was to determine
the emerging pattern and the role of the prostate specific antigen in the
detection of prostate cancer.
Methodology: A retrospective cross sectional study
using secondary data was carried out. Prostate specific antigen results of 176
outpatients who visited a small medical facility in the Midlands Province of
Zimbabwe were retrieved. Of these 26 proceeded to have biopsies done and the
histology reports were retrieved and analyzed. The data was analyzed using
Graph Pad Prism 6 software.
Results: 14.2% of the patients were confirmed
by biopsy to have prostate cancer. Prostate specific antigen levels of greater than
20 ng/ml were associated with biopsy confirmed Prostate Cancer.
Conclusion: It was found out that Prostate Cancer
is a major health problem in Zimbabwean men. Despite the low specificity of the
prostate specific antigen, the test still plays a major role in the detection
of prostate cancer. The age of those with confirmed Prostate Cancer is going
down. There is need for improved health budget and public health education in
Zimbabwe.
