David H. Aggen, MD, PhD, on Advanced Bladder Cancer: HER2 and PD-L1 Immunohistochemistry and HER2 Genomic Alterations
2024 ASCO GU Cancers Symposium
David H. Aggen, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses reportedly the first data to describe an inverse correlation between HER2 immunohistochemistry expression and PD-L1 combined positive score. According to Dr. Aggen, these and other findings by his team may provide a foundation for further HER2-directed advanced bladder cancer studies (Abstract 538).

Syed Muneeb Alam, MD, of Memorial Sloan Kettering Cancer Center, discusses study findings evaluating links among microsatellite instability status, tumor mutational burden, and response to immune checkpoint blockade in patients with microsatellite instability–high urothelial carcinoma (Abstract 536).

Neeraj Agarwal, MD, of Huntsman Cancer Institute at the University of Utah, discusses results of the CONTACT-2 trial, which showed cabozantinib plus atezolizumab improved radiographic progression–free survival of patients with metastatic castration-resistant prostate cancer vs a second novel hormonal therapy (NHT) in patients who had experienced disease progression on a prior NHT and have extrapelvic nodal or visceral disease. The benefits were more pronounced in patients with liver metastasis and in those who previously received docetaxel (Abstract 18).

Saby George, MD, of Roswell Park Comprehensive Cancer Center, discusses pharmacokinetics, efficacy, and safety results from CheckMate 67T, a phase III trial comparing the use of subcutaneous vs intravenous nivolumab in patients with advanced or metastatic clear cell renal cell carcinoma who have received prior systemic therapy (Abstract LBA360).

Andrew Johns, MD, of The University of Texas MD Anderson Cancer Center, discusses efficacy, safety, and tolerability data on tivozanib. The agent yielded a modest clinical benefit in a minority of patients with advanced clear cell renal cell carcinoma who received prior immune checkpoint–based therapies, cabozantinib, and lenvatinib with or without everolimus (Abstract 419).

Umang Swami, MD, of Huntsman Cancer Institute at the University of Utah, describes the molecular and immunologic mechanisms of metastatic tropism in advanced prostate cancer, data that may facilitate future drug development. In patients with metastatic disease, specific sites are associated with differential overall survival, but the biological reasons have not been fully explored (Abstract 21).
