Secondary hormone therapy, abiraterone and enzalutamide, has improved outcomes for metastatic castration-resistant prostate cancer (mCRPC) and prolonged patients’ lives significantly. Various studies have compared the cancer-related outcomes, adverse effects, and drug-induced comorbidities in patients with mCRPC who are treated with abiraterone or enzalutamide. However, few studies have explored associations between survival and comorbidities or comprehensive analyzed newly developed comorbidities during and after secondary hormone therapy. We attempted to clarify whether the Charlson comorbidity index (CCI) overall or itemized is predictive for overall survival, and we compared newly developed comorbidities between abiraterone and enzalutamide groups. We extracted data about expenses and comorbidities for patients who have mCRPC, received abiraterone and enzalutamide and met pre-examination operation criteria between September 2016 and December 2017 from the Taiwan National Health Insurance database. A total of 1153 patients with mCRPC who received abiraterone (n = 782) or enzalutamide (n = 371) with or without previous chemotherapy were included. We used the propensity score to match confounding factors, including age, pre-existing comorbidities, and precipitating factors for comorbidity (e.g., hypertension, hyperlipidemia), to eliminate selection bias in the comparison of newly developed comorbidities. Cox regression analysis was used for overall survival. We found that enzalutamide is superior to abiraterone with regard to overall survival. Our study revealed that there is no statistically significant difference in development of new comorbidities between abiraterone and enzalutamide group. Moreover, the CCI score, rather than any single item of the CCI, was a statistically significant predictor for overall survival.

321 Background: Recently, new androgen pathway inhibitors, abiraterone and enzalutamide, are demonstrated to improve overall survival for metastatic castration-resistant prostate cancer (mCRPC). In Japan, alternative antiandrogen (AA) as second-line hormonal therapy for mCRPC that relapses after initial hormone therapy have been commonly used before new androgen pathway inhibitors. In this study, we attempted to identify the predictive factors for efficacy of AA as second-line hormone therapy. Methods: We identified consecutive 65 mCRPC patients treated with AA as second-line hormonal therapy. All patients were treated with maximum androgen blockade (MAB) initially and evaluated antiandrogen withdrawal syndrome after relapse. We analyzed the correlations between progression-free survival (PFS) of AA and clinicopathological characteristics, including patients’ age, initial PSA levels, PSA levels at flutamide induction, Gleason scores, T stage, N stage, extent of disease (EOD) classifications on bone scan, and the previous duration of prostate cancer sensitivity to MAB. Results: The median duration of prostate cancer sensitivity to MAB was 11.3 months (range: 1.5-53.0 months). In multivariate analysis, four significant risk factors for poor PFS were identified; initial PSA levels ( > 263 ng/mL vs ≤ 263; HR 0.53, p = 0.038), N stage (1 vs 0; HR 3.00, p = 0.001), EOD classifications (3-4 vs 1-2; HR 2.50, p = 0.007), and the previous duration of prostate cancer sensitivity to MAB ( < 12 months vs ≥ 12; HR 2.16, p = 0.026). We stratified the patients into two cohorts with low risk (0-2 risk factor present) and high risk (3-4 risk factors present). We found a significant difference in PFS among risk groups (median PFS 7.3 months vs 1.5, p < 0.000). Conclusions: Initial PSA, N stage, EOD classifications on bone scan, and the previous duration of prostate cancer sensitivity to MAB were the significant predictive factors for efficacy of AA as second-line hormone therapy in patients with mCRPC. These findings might support that decision-making of when to start the new AR pathway inhibitors.
