Prevalence of prostate cancer and its grade group stage at diagnosis in patients treated with prostatectomy in rural south western Uganda.

BACKGROUND

Prostate cancer is the most frequently diagnosed cancer among men in the world. Uganda and Zimbabwe have been reported to have highest incidence rates of prostate cancer in sub-Saharan Africa. There are no urologists and no prostate cancer diagnostic facilities in rural communities in south western Uganda. Men with lower urinary tract symptoms are treated with prostatectomy by midlevel healthcare workers and general surgeons without prior prostate cancer screening. Histological diagnosis relies on the prostate tissue retrieved during surgery and the results may take several months. Prostate cancer care in southwestern Uganda remains uncoordinated and has not been documented before. This study aimed to establish and document the burden of prostate cancer in rural southwestern Uganda as a basis for further research.

METHODS

This was a retrospective study conducted in hospitals in rural southwestern Uganda. We used hospital records as primary source of data. Histology results of patients treated with prostatectomy during the five-year period (2019-2023) were retrieved and data extracted for analysis. 1013 patients were included in the study. Univariate data analysis was done with STATA version 17.0. The study received ethics clearance for Kabale university REC and Uganda National council of Science and Technology.

RESULTS

The average age of patients in this study was 70.6 year (range 54-102 years). Prostate cancer was present in 232 (22.9%) patients. Seventeen (7.3%) patients with prostate cancer were below sixty years. Most (75.4%) of the patients with prostate cancer in this study had low to intermediate risk disease. Perineural tumor infiltration was present in 28.9% of prostate cancer patients.

CONCLUSION

More than 1 in 5 men (22.9%) with lower urinary tract symptoms treated with prostatectomy in the study period in southwestern Uganda had prostate cancer. Majority of patients (75.4%) had low to intermediate risk disease. These findings highlight the urgent need for systematic improvements in prostate cancer care, including sensitization of both health workers and the general population, establishment of early screening and regional diagnostic and treatment facilities to enhance patient outcomes in resource -limited rural communities in Uganda.
