Treatment Plans

The treatment landscape for metastatic castration-sensitive prostate cancer (mCSPC) has rapidly evolved over the past 5 years. Although androgen-deprivation therapy (ADT) is still the backbone of treatment, the addition of docetaxel or abiraterone acetate has improved outcomes for patients with mCSPC and become standard of care. With multiple treatment options available for patients with mCSPC, treatment selection to optimize patient outcomes has become increasingly difficult. Here, we review the clinical trials involving ADT plus docetaxel or abiraterone and provide clinicians with guidelines for treatment. Although surgery and/or radiation are standard of care for localized, intermediate- and high-risk prostate cancer, these treatments are not routinely used as part of initial treatment plans for patients with de novo mCSPC. Recent clinical data are challenging that dogma, and we review the literature on the addition of surgery and radiation to systemic therapy for mCSPC. Finally, the standard of care for oligometastatic prostate cancer (a subset of mCSPC with limited metastases) has not been established compared with that for some other cancers. We discuss the recent studies on metastasis-directed therapy for treatment of oligometastatic prostate cancer.

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]

Oligometastatic Prostate Cancer

Oligometastatic prostate cancer (PCa) can be defined as cancer with a limited number of metastases, typically fewer than 5 lesions, and involves lesions contained within the axial versus the appendicular skeleton. Patients can present with de novo oligometastatic, oligorecurrent, or oligoprogressive PCa. Oligometastatic PCa patients demonstrate considerable improvements in survival outcomes, with a better prognosis than patients with extensive metastatic disease. However, the management of patients that present with nonsymptomatic oligometastatic PCa remains difficult. In the oligometastatic setting, the benefit of local therapies such as prostatectomy and radiotherapy on survival outcomes is an intriguing topic; however, their impact on oncological outcomes is still unknown.

PURPOSE The STAMPEDE trial recruits men with newly diagnosed, high-risk, hormone-sensitive prostate cancer. To ascertain the feasibility of targeted next-generation sequencing (tNGS) and the prevalence of baseline genomic aberrations, we sequenced tumor and germline DNA from patients with metastatic prostate cancer (mPCa) starting long-term androgen-deprivation therapy (ADT). METHODS In a 2-stage approach, archival, formalin-fixed, paraffin-embedded (FFPE) prostate tumor core biopsy samples were retrospectively subjected to 2 tNGS assays. Prospective enrollment enabled validation using tNGS in tumor and germline DNA. RESULTS In stage 1, tNGS data were obtained from 185 tumors from 287 patients (65%); 98% had de novo mPCa. We observed PI3K pathway aberrations in 43%, due to PTEN copy-number loss (34%) and/or activating mutations in PIK3 genes or AKT (18%) and TP53 mutation or loss in 33%. No androgen receptor ( AR) aberrations were detected; RB1 loss was observed in < 1%. In stage 2, 93 (92%) of 101 FFPE tumors (biopsy obtained within 8 months) were successfully sequenced prospectively. The prevalence of DNA damage repair (DDR) deficiency was 14% (somatic) and 5% (germline). BRCA2 mutations and mismatch repair gene mutations were exclusive to high-volume disease. Aberrant DDR (22% v 15%), Wnt pathway (16% v 4%), and chromatin remodeling (16% v 8%) were all more common in high-volume compared with low-volume disease, but the small numbers limited statistical comparisons. CONCLUSION Prospective genomic characterization is feasible using residual diagnostic tumor samples and reveals that the genomic landscapes of de novo high-volume mPCa and advanced metastatic prostate cancer have notable similarities (PI3K pathway, DDR, Wnt, chromatin remodeling) and differences ( AR, RB1). These results will inform the design and conduct of biomarker-directed trials in men with metastatic hormone-sensitive prostate cancer.

211 Background: Low-volume de novo metastatic hormone-sensitive prostate cancer (mHSPC) has historically been treated with lifelong androgen deprivation therapy (ADT). Recently, however, the addition of several advanced therapeutic options – radiation therapy (RT) to the primary, advanced hormonal therapy agents such as abiraterone acetate/prednisone (AAP), and chemotherapy – to ADT have been shown to improve survival in low-volume mHSPC. The objective of this study was to compare the cost-effectiveness of treating low-volume mHSPC patients upfront with RT+ADT, AAP+ADT, or docetaxel+ADT. Methods: A Markov-based cost-effectiveness analysis was constructed comparing three treatment strategies for low-volume mHSPC patients: (1) upfront RT+ADT --> salvage AAP+ADT --> salvage docetaxel+ADT; (2) upfront AAP+ADT --> salvage docetaxel+ADT, and (3) upfront docetaxel+ADT --> salvage AAP+ADT. Transition probabilities were calculated using data from STAMPEDE arms C/G/H, COU-AA-301, COU-AA-302, and TAX-327. RT was delivered via five-fraction stereotactic body radiation therapy. The analysis utilized a 10-year time horizon, and a $100,000/quality adjusted life year (QALY) willingness-to-pay threshold. Utilities were extracted from the literature; costs were taken from Medicare fee schedules and VA oral drug contracts. Results: At 10 years, total cost was $140K, $259K, and $189K, with total QALYs of 4.66, 5.03, and 3.72 for strategies (1) upfront RT+ADT, (2) upfront AAP+ADT, and (3) upfront docetaxel+ADT, respectively. Compared to upfront RT+ADT, upfront AAP+ADT was not cost-effective (ICER: $321K/QALY). This result remained unchanged even after modification of various model inputs in 1-way sensitivity analysis. Upfront docetaxel+ADT was both more costly and less effective than upfront RT+ADT (ICER: -$53K/QALY). Conclusions: At 10 years, RT+ADT is cost-effective compared to other advanced systemic therapy options alone, and should be considered as a viable treatment strategy in all patients with a low-burden of metastatic disease. Additional studies are needed to determine whether any benefit exists in combining RT to the primary with upfront advanced systemic therapy.
