INTRODUCTION: Prostate cancer (PCa) is the commonest urologic cancer worldwide and the leading cause of male cancer deaths in Nigeria. In Nigeria, orchidectomy remains the primary androgen deprivation therapy. Dihydrotestosterone (DHT) is the active prostatic androgen, but its relationship with PCa severity has not been extensively studied in Africa.
OBJECTIVES: This study assessed the relationship between serum levels of DHT (pre- and post-orchidectomy) and serum prostate specific antigen (PSA), as well as Gleason scores.
METHODS: Patients undergoing orchidectomy for histologically confirmed prostate adenocarcinoma were studied. Serum PSA and DHT levels were assessed before orchidectomy, and 6 weeks afterwards. This was correlated with their Gleason scores. Data was analyzed using the IBM SPSS Statistics version 20. P < 0.05 was considered significant.
RESULTS: Fifty-three patients completed the study. The mean age was 69.3 ± 6.9 years. Pre- and post-orchidectomy serum PSA ranged from 11.30 to 562.00 ng/ml and 0.01ng/mL to 245.00 ng/mL respectively. Pre- and post-orchidectomy DHT ranged from 6.91ng/mL to 4,996.38 ng/mL and 6.56 ng/mL to 2,575.03 ng/mL respectively. Up to 40% still had normal DHT post-orchidectomy. There was a positive but statistically insignificant correlation between pre-orchidectomy serum PSA and DHT (r = 0.089, p = 0.527). There was however a direct and significant relationship between pre-orchidectomy serum DHT and Gleason scores (p = 0.042).
CONCLUSION: This study showed a relationship between preorchidectomy serum DHT and Gleason scores. Assessing DHT in patients with high Gleason scores could influence hormonal manipulation.
