What Clinicians Want to Know: Addressing Community Oncologists’ Questions About the Care of Patients with Prostate Cancer — Symposium Proceedings

Faculty

TARGET AUDIENCE
This activity is intended for medical oncologists, hematologists, hematology-oncology fellows, radiation oncologists, surgeons and other allied healthcare professionals involved in the treatment of prostate cancer.

LEARNING OBJECTIVES

• Infer how various clinical and biological factors affect the risk of prostate cancer recurrence after local therapy, and design appropriate treatment plans for patients with consideration of the risks and potential benefits of new and established forms of hormonal therapy.
• Appraise published research findings on optimal therapeutic approaches for patients with biochemical recurrence after local therapy for prostate cancer, and counsel appropriate candidates regarding the potential benefits of FDA-approved systemic treatment options.
• Evaluate the published research database supporting the FDA approvals of secondary hormonal agents in the management of nonmetastatic prostate cancer, and apply this information in the discussion of nonresearch treatment options for patients.
• Explore available data with treatment intensification with cytotoxic therapy, secondary hormonal therapy or combinations of these approaches for metastatic hormone-sensitive prostate cancer (mHSPC), and effectively integrate these strategies into clinical management algorithms.
• Assess the available and emerging research database supporting the use of PARP inhibitors in combination with androgen receptor pathway inhibitors for patients with metastatic prostate cancer harboring a homologous recombination repair gene alteration, and discern how to optimally incorporate these agents into clinical management algorithms.
• Appreciate the biological rationale for targeting the PI3K/AKT/mTOR pathway in prostate cancer, and evaluate available data with novel AKT inhibitors in combination with hormonal therapy for patients with mHSPC and PTEN deficiency.
• Review available Phase III data documenting the efficacy of various forms of radioligand therapy for patients with metastatic prostate cancer, and consider the current and future clinical role of these strategies.
• Recall the design of ongoing clinical trials evaluating other novel agents and strategies for prostate cancer, and appropriately counsel patients about availability and participation.
