TARGET AUDIENCE
This activity is intended for medical oncologists, breast surgeons, radiation oncologists and other healthcare professionals involved in the diagnosis and treatment of breast cancer.

LEARNING OBJECTIVES

• Review available research documenting the correlation between the presence of various biomarkers (eg, PIK3CA/AKT1/PTEN alterations, ESR1 mutations) and response to specific therapies, and develop optimal testing algorithms for patients with hormone receptor (HR)-positive metastatic breast cancer (mBC).
• Recognize the frequency of PIK3CA/AKT1/PTEN alterations in patients with HR-positive mBC, and employ evidence-based approaches designed to target these aberrations as appropriate for those with newly diagnosed and relapsed/refractory disease.
• Understand the biological rationale for the development of agents targeting multiple components of the PI3K/AKT/mTOR pathway, and recognize available data with this strategy for patients with HR-positive, PIK3CA wild-type and PIK3CA-mutant mBC.
• Evaluate available research findings with and ongoing studies evaluating novel PI3K/AKT/mTOR inhibitor-based approaches, and consider the potential role of these strategies in clinical practice.

TARGET AUDIENCE
This activity is intended for medical and radiation oncologists, urologists and other healthcare providers involved in the treatment of genitourinary cancers.

LEARNING OBJECTIVES

• Evaluate recently presented clinical research findings to determine their effect on the current management of localized or metastatic prostate cancer.
• Explore available data with treatment intensification for hormone-sensitive localized or metastatic prostate cancer, and effectively integrate FDA-approved strategies into current clinical management algorithms.
• Assess the available research database supporting 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 current clinical management algorithms.
• Appreciate the biological rationale for targeting the PI3K/AKT/mTOR pathway for prostate cancer, and evaluate available data with novel AKT inhibitors in combination with hormonal therapy for patients with PTEN deficiency.
• Review available Phase III data documenting the efficacy of various forms of radioligand therapy for metastatic prostate cancer, and consider the current and potential future clinical role of these strategies.
• Optimize the management of non-muscle-invasive bladder cancer (NMIBC), considering the efficacy and tolerability of FDA-endorsed and other emerging novel therapeutic strategies.
• Appraise clinical research findings with perioperative anti-PD-1/PD-L1 antibody therapy alone and in combination with antibody-drug conjugate therapy for muscle-invasive bladder cancer (MIBC).
• Develop an understanding of the clinical relevance of circulating tumor DNA (ctDNA) as a prognostic and predictive biomarker for MIBC, and evaluate available research data documenting the benefit of adjuvant anti-PD-1/PD-L1 antibody therapy for patients who are ctDNA positive following cystectomy.
• Appreciate how various clinical and biological factors, including prior therapeutic exposure, affect the selection and sequencing of therapy for patients with metastatic urothelial bladder cancer (UBC).
• Develop a rational approach to the sequencing of systemic therapies for patients with advanced renal cell carcinoma (RCC), incorporating immunotherapeutic agents, multikinase inhibitors, HIF-2α inhibitors or combinations of these approaches.
• Appreciate published clinical research findings evaluating available and investigational agents for non-clear cell RCC, and consider the applicability of these strategies in current clinical care.
• Recall available and emerging data with other novel and investigational agents and strategies currently in testing for prostate cancer, UBC and RCC, and refer eligible patients for clinical trial participation.

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 lung cancer.

LEARNING OBJECTIVES

• Appraise available findings from clinical studies investigating anti-PD-1/PD-L1 antibody consolidation therapy for patients with limited-stage small cell lung cancer (SCLC) who have not experienced disease progression after standard platinum-based chemotherapy concurrent with radiation therapy, and determine the clinical role of this approach.
• Review long-term data supporting the use of anti-PD-1/PD-L1 antibodies in combination with platinum-based chemotherapy as first-line therapy for patients with extensive-stage SCLC, and consider how these regimens can be appropriately and safely integrated into clinical practice.
• Appreciate the biological rationale for the evaluation of maintenance treatment after chemoimmunotherapy induction, and assess available research findings with and the current role of this approach.
• Evaluate available clinical trial findings with FDA-approved agents for patients with SCLC who experience disease progression on or after platinum-containing first-line therapy, and determine how to optimally integrate these therapies into current treatment algorithms.
• Interrogate published clinical trial data with DLL3-directed T-cell engager therapy for SCLC, and identify patients with relapsed/refractory (R/R) disease appropriate for this novel approach.
• Appreciate the incidence of B7-H3 overexpression in patients with SCLC, and develop an understanding of the rationale for, available data with and ongoing studies of B7-H3-directed antibody-drug conjugates for R/R disease.
• Reflect on the biological rationale for the evaluation of TROP2-directed antibody-drug conjugates for SCLC, and consider available research findings and ongoing studies with these agents.
• Assess ongoing clinical research studies evaluating other novel agents and treatment strategies for SCLC, and counsel patients regarding the potential benefits of trial participation.
