Circulating neuromediators in chemotherapy-naïve CRPC patients were elevated in a high percentage of patients. ADT was found to be a relevant NED driver in this cohort. Our results may imply that patients with CRPC after first-line treatment with AA in CRPC are not at a higher risk for developing NED. The major limitation of the study represents the one-time analysis of neuromediators. Larger studies with serial blood measurements or biopsy analysis before and after treatment are needed to confirm our results.

Patients with an early high CGA rise may demonstrate a subgroup with poor outcome due to underlying SCNC transformation. Monitoring of CGA appears to be an option worth considering.

Purpose To report on long-term outcomes of patients treated with active surveillance (AS) for localized prostate cancer (PCa) in the daily routine setting. Methods HAROW (2008–2013) was a non-interventional, health service research study about the management of localized PCa in the community setting, with 86% of the study centers being office-based urologists. A follow-up examination of all patients who opted for AS as primary treatment was carried out. Overall, cancer-specific, and metastasis-free survival, as well as discontinuation rates, were determined. Results Of 329 patients, 62.9% had very-low- and 21.3% low-risk tumours. The median follow-up was 7.7 years (IQR 4.7–9.1). Twenty-eight patients (8.5%) died unrelated to PCa, of whom 19 were under AS or watchful waiting (WW). Additionally, seven patients (2.1%) developed metastasis. The estimated 10-year overall and metastasis-free survival was 86% (95% CI 81.7–90.3) and 97% (95% CI 94.6–99.3), respectively. One hundred eighty-seven patients (56.8%) discontinued AS changing to invasive treatment: 104 radical prostatectomies (RP), 55 radiotherapies (RT), and 28 hormonal treatments (HT). Another 50 patients switched to WW. Finally, 37.4% remained alive without invasive therapy (22.2% AS and 15.2% WW). Intervention-free survival differed between the risk groups: 47.8% in the very-low-, 33.8% in the low- and 34.6% in the intermediate-/high-risk-group (p = 0.008). On multivariable analysis, PSA-density ≥ 0.2 ng/ml2 was significantly predictive for receiving invasive treatment (HR 2.55; p = 0.001). Conclusion Even in routine care, AS can be considered a safe treatment option. Our results might encourage office-based urologists regarding the implementation of AS and to counteract possible concerns against this treatment option.

Background: Limited data are available for the use of agents in metastatic castration-resistant prostate cancer (mCRPC) beyond the third-line. We provide data during treatment with cabazitaxel (CAB), helping to improve the informed-consent process. Patients and Methods: We retrospectively reviewed patients treated with fourth-line or beyond CAB for mCRPC after failure of previous therapies with docetaxel, abiraterone acetate, enzalutamide and/or radium-223. The progression-free survival (PFS) and the overall survival (OS) were estimated using the Kaplan-Meier method and compared to published data based on a structured literature review. The hospitalization rate was recorded. Factors influencing 6-months OS were analyzed. Results: Fifteen patients were identified at 4 institutions and included in the analysis. The median PFS was 104 days (range 47-397 days). The median time to death was 10 months (range 2-16). PFS and OS data are in accordance with 17 published patients so far. During the therapy, eleven (73%) of the patients were hospitalized. Prostate-specific antigen (PSA, 500 units; hazards ratio [HR] 1.491, 95% CI 1.000-2.0175), white blood cell count (HR 0.425, 95% CI 0.108-0.952), hemoglobin (HR 0.6014, 95% CI 0.2942-1.0758), and alkaline phosphatase (100 units; HR 1.0964, 95% CI 1.000-1.2859) correlate with 6-months OS. Conclusions: CAB beyond the third-line is often accompanied by hospitalization. PFS is a significant proportion of the median time of OS. The baseline laboratory might be a good indicator for the decision between CAB and best-supportive care.
