Objective: To date, there are no useful markers for predicting the prognosis of metastatic hormone-sensitive prostate cancer (mHSPC). We evaluated the effect of early changes in prostate-specific antigen (PSA) levels after androgen deprivation therapy (ADT) on castration-resistant prostate cancer (CRPC) progression and overall survival (OS) in mHSPC patients.
Results: In 71 primary mHSPC patients treated with ADT, the median times to CRPC and OS were 15 months and 92 months, respectively. In multivariate analysis, a Gleason score of ≥8 (p = 0.004), an extent of disease value (EOD) of ≥2 (p = 0.004), and a 3-month PSA level >1% of the pretreatment level (p = 0.017) were independent predictors of shorter time to CRPC. The area under the receiver operating characteristic curve was feasible at 0.822. For OS, a 3-month PSA level >1% of the pretreatment level was an independent predictor of time to CRPC (p = 0.004).
Three factors were independent predictors of shorter time to CRPC. A 3-month PSA level >1% of the pretreatment level correlated with poor a prognosis.
