194 Background: Diagnoses of cancer distress both patients and their partners. Providing accurate information about diagnosis and treatment options promotes active and informed decision-making and can decrease distress and anxiety. We sought to determine whether an education session alleviated distress for both prostate cancer (PC) patients and their partners, and whether their partner’s attendance at the session, as well as specific disease, treatment, and socio-demographic characteristics affect changes in distress levels. Methods: The session consists of a 90-minute didactic presentation, followed by an 8- to 10-minute private session with a urologist and radiation oncologist. We assessed distress using the Distress Thermometer (DT) and compared pre- and post-session distress, and change in distress between patients and partners using matched and unmatched t-tests. We also assessed before-the-session anxiety using the Generalized Anxiety Disorder measure (GAD), and decisional certainty using the Decisional Conflict Scale. Results: 71 patients and 48 partners participated in the study. Attending the session led to a significant reduction in median DT score for both patients (4.0 to 3.0, p = 0.0009) and partners (5.0 vs. 4.0, p = 0.0176). Partners reported higher distress both before and after the session compared to patients (4.9 vs. 3.8, p = 0.025 pre-session and 4.2 vs. 3.1, p = 0.032 post-session). The presence of a partner at the session did not appear to affect patients’ pre- or post-session distress nor the success of the session at alleviating distress. Sociodemographic and clinical characteristics had little effect on distress levels. Conclusions: Our study demonstrates that an interdisciplinary education session is equally effective at alleviating distress for both PC patients and their partners. These results can be used to guide the development of supportive care programs more broadly in terms of their ability to address the physiological and psychological needs of PC patients and their families.

Combination Treatments

Background: Prostate cancer is the second most common cancer in American men. The development of alternative preventative and/or treatment options utilizing a combination of phytochemicals and chemotherapeutic drugs could be an attractive alternative compared to conventional carcinoma treatments. Genistein isoflavone is the primary dietary phytochemical found in soy and has demonstrated anti-tumor activities in LNCaP prostate cancer cells. Topotecan Hydrochloride (Hycamtin) is an FDA-approved chemotherapy for secondary treatment of lung, ovarian and cervical cancers. The purpose of this study was to detail the potential activation of the intrinsic apoptotic pathway in LNCaP prostate cancer cells through genistein-topotecan combination treatments. Methods: LNCaP cells were cultured in complete RPMI medium in a monolayer (70-80% confluency) at 37ºC and 5% CO2. Treatment consisted of single and combination groups of genistein and topotecan for 24 hours. The treated cells were assayed for i) growth inhibition through trypan blue exclusion assay and microphotography, ii) classification of cellular death through acridine/ ethidium bromide fluorescent staining, and iii) activation of the intrinsic apoptotic pathway through Jc-1: mitochondrial membrane potential assay, cytochrome c release and Bcl-2 protein expression.Results: The overall data indicated that genistein-topotecan combination was significantly more efficacious in reducing the prostate carcinoma’s viability compared to the single treatment options. In all treatment groups, cell death occurred primarily through the activation of the intrinsic apoptotic pathway.Conclusion: The combination of topotecan and genistein has the potential to lead to treatment options with equal therapeutic efficiency as traditional chemo- and radiation therapies, but lower cell cytotoxicity and fewer side effects in patients.

Prostate cancer is one of the leading causes of death in men all over the world. Treatment options such as androgen ablation therapy and cytotoxic agents have many undesirable side effects, narrow therapeutic windows, or other limitations. In this research, we have explored the effects of paeonol on prostate cancer and its mechanism of action. Our results have shown that paeonol reduced the viability of prostate cancer cells in a dose-dependent manner. The wound-healing assay, a surrogate marker of tumor metastasis, showed that the relative wound width of 10 µM group was less than that of 50 µM paeonol-treated cells. Besides, the results of the transwell assay also showed that the number of migrated cells was significantly lower after treatment with 50 µM paeonol compared to the 10 µM group. The Western blot results showed that paeonol treatment induced a decrease in the mesenchymal markers (vimentin and N-cadherin), while the epithelial marker (E-cadherin) increased in a dose-dependent manner suggesting that paeonol effectively inhibits the epithelial-mesenchymal transformation in PC3 cells. Furthermore, the expression of STAT3 and p-STAT3 was also decreased after paeonol treatment, which indicated that the STAT3 signaling pathway was inhibited by paeonol. To conclude, the results summarized in this paper suggest that paeonol could be a potential candidate in the treatment of prostate cancer.

Over the past decade, advances in prostate cancer research have led to discovery and development of novel biomarkers and effective treatments. As treatment options diversify, it is critical to further develop and use optimal biomarkers for the purpose of maximizing treatment benefit and minimizing unwanted adverse effects. Because most treatments for prostate cancer target androgen receptor (AR) signaling, aberrations affecting this drug target are likely to emerge following the development of castration-resistant prostate cancer (CRPC), and it is conceivable that such aberrations may play a role in drug resistance. Among the many AR aberrations, we and others have been studying androgen receptor splice variants (AR-Vs), especially AR-V7, and have conducted preclinical and clinical studies to develop and validate the clinical utility of AR-V7 as a prognostic and potential predictive biomarker. In this review, we first describe mechanisms of AR-V generation, regulation and their functions from a molecular perspective. We then discuss AR-Vs from a clinical perspective, focusing on the significance of AR-Vs detected in different types of human specimens and AR-Vs as potential therapeutic targets.

Abstract Background Emerging moderately hypofractionated and ultra-hypofractionated schemes for radiotherapy (RT) of prostate cancer (PC) have resulted in various treatment options. The aim of this survey was to evaluate recent patterns of care of German-speaking radiation oncologists for RT of PC. Methods We developed an online survey which we distributed via e‑mail to all registered members of the German Society of Radiation Oncology (DEGRO). The survey was completed by 109 participants between March 3 and April 3, 2020. For evaluation of radiation dose, we used the equivalent dose at fractionation of 2 Gy with α/β = 1.5 Gy, equivalent dose (EQD2 [1.5 Gy]). Results Median EQD2(1.5 Gy) for definitive RT of the prostate is 77.60 Gy (range: 64.49–84.00) with median single doses (SD) of 2.00 Gy (range: 1.80–3.00), while for postoperative RT of the prostate bed, median EQD2(1.5 Gy) is 66.00 Gy (range: 60.00–74.00) with median SD of 2.00 Gy (range: 1.80–2.00). For definitive RT, the pelvic lymph nodes (LNs) are treated in case of suspect findings in imaging (82.6%) and/or according to risk formulas/tables (78.0%). In the postoperative setting, 78.9% use imaging and 78.0% use the postoperative tumor stage for LN irradiation. In the definitive and postoperative situation, LNs are irradiated with a median EQD2(1.5 Gy) of 47.52 Gy with a range of 42.43–66.00 and 41.76–62.79, respectively. Conclusion German-speaking radiation oncologists’ patterns of care for patients with PC are mainly in line with the published data and treatment recommendation guidelines. However, dose prescription is highly heterogenous for RT of the prostate/prostate bed, while the dose to the pelvic LNs is mainly consistent.

Chemotherapy treatment options are limited for patients with castration-resistant prostate cancer (CRPC). The purpose of this study is to report treatment use and adverse effects (AEs) within the last three months of life in patients with CRPC. Of the 88 patients identified, 32% received treatment within 3 months of death, and documented AEs occurred in 25% of patients. Of those, neutropenia (18.3%), nausea/vomiting (18.3%), and febrile neutropenia (13.6%) were the most frequent. Results of this study show high treatment utility towards the end-of-life in patients with CRPC, with one fourth of patients experiencing AEs. Attention to health-related quality of life becomes increasingly important as new treatments appear to have small impact on survival, and AEs of those treatments may significantly impact patient quality of life.

279 Background: The PCSC Program was initiated in 2013 at the Vancouver Prostate Centre to provide a comprehensive program for patients and partners with prostate cancer. This program provides educational sessions (ES) and clinical services, including decision-making for primary therapy, sexual health, pelvic floor physiotherapy, hormone therapy, counseling, exercise, and nutrition for patients in BC, Canada. In 2016, the PCSC Program expanded to BC Cancer Victoria and in 2017 to other BC Cancer sites. In 2018, medical oncologists (MDs) in Victoria (JR, SP) developed an Education Module addressing treatment options for men with metastatic hormone sensitive (mHSPC) and metastatic castration resistant (mCRPC) disease. MDs delivered in-person ES in Victoria in 2018 and, in 2019, added a virtual platform (VP) option. From 3-5/2020, the ESs were on hold due to the COVID pandemic and parental leaves. In 6/2020, the ESs resumed only on VP, and the PCSC Oncology Nurse Practitioner (NP), NI, gave the presentations for the MDs on leave. In 10/2020, due to a changing standard of care for mHSPC, the PCSC team consolidated the two ESs into one. We report on the evolution of this Education Module in response to both the changing standard of care and the COVID pandemic. Methods: We prospectively collected attendance and patient characteristic metrics from all ES for men with mPC. We tracked presenter type (MD vs. NP) and prospectively collected anonymous patient satisfaction questionnaires. Results: From 1/2018 to 1/2021, 100 men registered for 27 ES; 81 men, 41 partners, and 2 family members actually attended. 48/75 (64%) men were white, 39/75 (52%) retired, and 56/75 (74.7%) married. 47 men attended 12 mHSPC ES, 13 men attended ten mCRPC ES, and 17 attended four consolidated ES. MDs presented 15 ES, and the NP presented 12 ES. Responses to questions on 70 satisfaction surveys were similar for MD vs. NP presenters. 9 responders to the recently added VP-specific questions said they agreed (4) or strongly agreed (5) that it was beneficial to watch the ES at home on a computer. The Table below shows attendance per site per year. Conclusions: The ESs for men with mPC were well-received. Although there was a VP option before COVID, attendance increased significantly after the lockdown as patients and providers became more familiar with VPs. Satisfaction surveys confirmed that an NP could deliver the ES rather than MD. Consolidation of the mHSPC and mCRPC ES reflected the changing standard of care and resulted in more efficient use of presenter time. Virtual delivery of the sessions provided greater access to those living in distant or remote areas of the province and those in lockdown during the COVID pandemic. [Table: see text]
