Background: Abiraterone acetate became a referral treatment for metastatic castration-resistant prostate cancer (mCRPC) in a post-docetaxel setting despite a remarkable percentage of cardiovascular adverse events (AEs). As a consequence, the evaluation of cardiovascular safety in patients at risk should be mandatory. We aimed to assess the cardiovascular safety of abiraterone acetate in a real-world series of mCRPC patients treated at our institution. Materials and Methods: We retrospectively included mCRPC patients with at least 1 active cardiovascular comorbidity or risk factor according to the European Society of Cardiology (ESC) guidelines and who started treatment with abiraterone acetate from April 2011 to July 2012. Cardiac assessment with electrocardiogram and echocardiogram was performed at baseline and at treatment discontinuation. AEs were defined according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Statistical analyses were performed by descriptive statistics as appropriate. Results: We included 51 patients of whom 18% had an ESC score risk for a major cardiovascular event ≥4%. At a median follow-up of 36 months, no cardiac AEs (rhythm abnormalities or left ventricular function decrease) were observed. The most frequent grade 1-2 AE reported was fluid retention (18%) followed by hypertension and asthenia (16%). The most frequent grade 3-4 AEs were asthenia and pruritus/rash. No patients discontinued abiraterone because of toxicity. Conclusions: Abiraterone acetate showed a favorable safety profile in mCRPC patients with cardiovascular comorbidities or risk factors in a post-docetaxel setting, but further studies are needed to confirm our findings and to explore other settings of disease.

e17571 Background: Abiraterone acetate and prednisolone (AAP) + ADT has been approved for treatment metastatic castration-resistant prostate cancer (CRPC) in the standard dose 1,000 mg with fasting state. Data in Ramathibodi hospital showed patients who had treated with standard dose of Abiraterone acetate (AA); had PSA response 47.83%. Previous studies showed using low dose AA of 250 mg with food had the non-inferiority results in efficacy. AA was not be reimbursed in Thailand, so the ability to use a highly effective drug at a quarter of the dose, could help in patient accessibility to cancer treatments. We sought to test the hypothesis that low-dose AA with food would have the comparable activity in Thai CRPC patients in both of the pre-Docetaxel and post Docetaxel treatment groups, and exploring the quality of life (QOL) of these patients. Methods: An observational cohort enrolled newly diagnosed metastasis CRPC at Ramathibodi hospital from 1st Jan 2019 to 31st Dec 2019. Patients were assigned to AA (250mg) with actual daily life meal. We collected the data of serum PSA and the adverse events every 4 weeks for 4 months. The QOL data was collected with the EuroQoL (EQ-5D) questionnaire which were done at baseline and every 4 weeks. The primary end point was PSA response that defined as PSA decreased ≥ 50% from PSA level at baseline. The secondary endpoint were the depth of PSA change, QOL and adverse events by using Fisher's exact test and T-test. Results: 21 patients were enrolled. At 12 weeks, there were 11 patients (52.38%) achieved 50% PSA response and 6 patients (28.57%) achieved 90% PSA response. The adverse events occurred 23.8%, and mostly were mild grade. The adverse events were comparable with the historical data in standard dose of AA. Low dose AA has significantly shown the improvement in quality of life from baseline (p < 0.001), and especially the significant improvement in pre-Docetaxel subgroup. Conclusions: Low-dose AA with food has good efficacy in PSA response, adverse events and QOL. Moreover, low dose AA shows more efficacy especially in pre-Docetaxel mCRPC patients. Low dose AA may be helping in reducing cost of cancer care, enabling in delivering affordable cancer care and increasing value of treatment.

Objectives: Among males, prostate cancer (PCa) is the most common cancer in Europe and the second most common cancer worldwide, especially in those aged > 70 years. With the advent of novel alternative treatments, survival in patients with advanced PCa has increased. PCa is now considered a chronic disease. Survival is an important endpoint in advanced PCa, as is quality of life (QoL). The effects of the disease and its treatment on patient health-related QoL must be taken into account when selecting the most appropriate treatment options. The present literature review aimed to provide an overview of metastatic castration-resistant prostate cancer treatment modalities, with an emphasis on side effect profiles and general health-related QoL. Methods: PubMed was searched using the keywords metastatic castration-resistant prostate cancer, docetaxel, cabazitaxel, enzalutamide, abiraterone acetate, and QoL. Conclusion: Based on the studies reviewed herein, abiraterone acetate and enzalutamide provide favorable outcomes, in terms of hematological adverse events. As enzalutamide and abiraterone acetate can be taken orally, they might have a positive effect on patient QoL.
