Purpose Docetaxel added to androgen-deprivation therapy (ADT) significantly increases the longevity of some patients with metastatic hormone-sensitive prostate cancer. Herein, we present the outcomes of the CHAARTED (Chemohormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer) trial with more mature follow-up and focus on tumor volume. Patients and Methods In this phase III study, 790 patients with metastatic hormone-sensitive prostate cancer were equally randomly assigned to receive either ADT in combination with docetaxel 75 mg/m2 for up to six cycles or ADT alone. The primary end point of the study was overall survival (OS). Additional analyses of the prospectively defined low- and high-volume disease subgroups were performed. High-volume disease was defined as presence of visceral metastases and/or ≥ four bone metastases with at least one outside of the vertebral column and pelvis. Results At a median follow-up of 53.7 months, the median OS was 57.6 months for the chemohormonal therapy arm versus 47.2 months for ADT alone (hazard ratio [HR], 0.72; 95% CI, 0.59 to 0.89; P = .0018). For patients with high-volume disease (n = 513), the median OS was 51.2 months with chemohormonal therapy versus 34.4 months with ADT alone (HR, 0.63; 95% CI, 0.50 to 0.79; P < .001). For those with low-volume disease (n = 277), no OS benefit was observed (HR, 1.04; 95% CI, 0.70 to 1.55; P = .86). Conclusion The clinical benefit from chemohormonal therapy in prolonging OS was confirmed for patients with high-volume disease; however, for patients with low-volume disease, no OS benefit was discerned.

140 Background: ADT is standard treatment for metastatic PCa. Recently, the E3805 trial reported a survival benefit for (ADT+D) in high volume disease (HVD) patients, whereas the GETUG-15 trial did not demonstrate a survival improvement among a less selected group of patients (pts) with hormone-naïve metastatic PCa. We report an updated analysis of overall survival (OS) of the GETUG 15 trial and aligned the definition of HVD and low volume disease (LVD) subgroups. Methods: Long-termOS was analyzed in the intention-to-treat population (n=385 pts). Additionally, we retrospectively assessed the tumor volume as defined per E3805criteria in all patients enrolled in GETUG 15. Results: See Table. With a median follow-up of 82.9 months (95%CI [80.5-84.3]) (vs 50 months (95%CI [80.5-84.3] in the original analysis), 212 patients (55%) have died. The median OS is 46.5 [39.1-60.6] and 60.9 months [46.1-71.4] in the ADT and in the ADT + D arms, respectively (HR: 0.9 [95%CI: 0.7-1.2]). In HVD patients (n=183, 47.5%), median OS rates were 35.1 months [29.9-44.2] in the ADT alone arm and 39 months [28-52.6] in the ADT+D arm (HR: 0.8 [0.6-1.2]). Conclusions: With longer follow-up, the addition of docetaxel to ADT did not significantly improve OS in patients with hormone-naïve metastatic prostate cancer. In the retrospective analysis using aligned definition of volume of metastasis as E3805, the HVD outcomes were similar to E3805 for ADT alone and there was a non-significant 4 months increase in OS with ADT+D, in this underpowered subset.

5020 Background: The HSD3B1(1245A > C) variant allele, whose frequency varies by race, encodes a missense sequence that stabilizes the rate-limiting enzyme responsible for extragonadal androgen synthesis, thus enhancing intratumoral dihydrotestosterone (DHT) synthesis. Multiple retrospective studies have found that men inheriting the HSD3B1(1245C) variant allele exhibit early resistance to ADT. We sought to validate these findings with prospective data from the Chemohormonal Therapy versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer (CHAARTED). Methods: Men with newly metastatic PCa were randomized to receive either ADT plus docetaxel at a dose of 75 mg/m2 every 3 weeks for 6 cycles (arm A) or ADT alone (arm B). We determined germline HSD3B1 genotype in the subset of men with LV disease ( < 4 bone metastases, no visceral metastases). We analyzed freedom from castration-resistant prostate cancer (CRPC) and OS according to HSD3B1 genotype using Cox and Kaplan-Meier methods. Results: 197 patients with LV disease had blood samples available and were genotyped, including 97 in arm A and 100 in arm B. Docetaxel did not improve OS of LV men. Of the 197 men, 47% were homozygous wild-type (WT), 43% were heterozygous, and 10% were homozygous variant. When all 197 men were analyzed as one goup, the median time to CRPC was 39.7 mos. in homozygous WT men vs. 25.0 mos. in men with one or more copies of the variant allele (HR 1.27, 95% CI 0.89 to 1.82; p = 0.187). Although OS data are still maturing, at 52 months OS was 83% (95% CI 75% to 91%) in homozygous WT men vs. 64% (95% CI 55% to 74%) in men with one or more variant alleles. There was a suggestion that docetaxel delayed development of CRPC among men with at least 1 variant allele (20.3 vs. 40.7 mos.; HR 0.66, 95% CI 0.40 to 1.04; p = 0.08). Benefit for men with high-volume disease was not evident. Conclusions: Inheritance of the HSD3B1(1245C) allele that augments DHT synthesis may be associated with lower OS in men treated with ADT with or without docetaxel for LV newly metastatic PCa. Additional study is warranted in patients with LV disease. Clinical trial information: NCT00309985.

The Way

Hormonal therapy has been the treatment axis of metastatic prostate cancer since 1940. Identifying rare forms of debut is important in order to initiate the best treatment as soon as possible. Intravascular disseminated coagulopathy (DIC) related to prostate cancer is mostly presented as chronic forms. Acute forms can also be the way of presentation, recognizing them is crucial due to its life threatening nature. Here, we present a case of debut of metastatic prostate cancer as an acute DIC. Reporting this case is important because of the unfrequently presentation and to consider combined chemohormonal therapy since the diagnosis.
