Prostate cancer (PCa) patients who are classified into the intermediate risk category represent a heterogeneous population needing further preoperative risk assessment.
To evaluate clinical total testosterone (TT) associations with lymph node invasion (LNI) in intermediate risk PCa.
Between November 2014 and July 2016, intermediate risk PCa was assessed in 154 patients who underwent extended pelvic lymph node dissection if the risk of LNI was higher than 5%. Clinical factors associated with the risk LNI were investigated by the multinomial logistic regression model.
The risk of LNI was assessed higher than 5% in 40.9% of cases of whom 15.5% had LNI. In the multivariate model, the risk of LNI was independently increased by prostate specific antigen (OR = 1.185; p = 0.021) and TT (OR = 1.004; p = 0.036). As a result, TT was an independent factor that associated with LNI because it increased the risk of LNI by 4% for each increment unit of TT.
Preoperative TT independently increased the risk of LNI in the intermediate risk class of PCa patients elected to radical prostatectomy and extended pelvic lymph node dissection. TT might be a useful preoperative factor for stratifying intermediate risk patients because of the positive association of TT with high grade tumors.
