Rana R. McKay, MD, of the University of California, San Diego, discusses the results of a phase II trial of intense neoadjuvant hormone therapy followed by radical prostatectomy in men with high-risk prostate cancer. The data show that 21% of patients had a favorable pathologic response (Abstract 5503).
Parameswaran Hari, MD, of the Medical College of Wisconsin, discusses data from four trials and their clinical implications for the treatment of patients with multiple myeloma: the KarMMa and EVOLVE studies on CAR T cell therapies; SWOG-1211 on bortezomib, lenalidomide, and dexamthasone with/without elotuzumab for newly diagnosed, high-risk disease; and the GMMGCONCEPT trial on isatuximab, carfilzomib, lenalidomide, and dexamethasone in front-line treatment (Abstracts 8503, 8504, 8507, 8508).
David R. Wise, MD, PhD, of New York University Perlmutter Cancer Center, summarizes three important studies in prostate cancer: circulating tumor cell count as a prognostic marker of PSA response and progression in metastatic castration-sensitive disease; new phenotypic subtypes; and how circulating tumor DNA dynamics associate with treatment response and radiologic progression-free survival (Abstracts 5506, 5507, and 5508).
Sara A. Hurvitz, MD, of UCLA’s David Geffen School of Medicine, summarizes four breast cancer studies: KATHERINE, on adjuvant trastuzumab vs trastuzumab in patients with residual invasive disease after neoadjuvant therapy for HER2-positive breast cancer; KAITLIN, on trastuzumab emtansine and pertuzumab vs trastuzumab, pertuzumab, and taxane after anthracyclines as adjuvant therapy for high-risk HER2-positive early breast cancer; TRAIN-2, on neoadjuvant chemotherapy with or without anthracyclines for HER2-positive disease; and PHERGain, on chemotherapy de-escalation using an FDG-PET/CT and pathologic response–adapted strategy in HER2-positive early breast cancer (Abstracts 500, 501, 502, and 503).
Lakshmi Nayak, MD, of Dana-Farber Cancer Institute, reviews two key abstracts on newly diagnosed primary central nervous system lymphoma and treatment with whole-brain radiotherapy, methotrexate, temozolomide, rituximab, procarbazine, vincristine, and cytarabine (Abstracts 2500 and 2501).
Peter Reichardt, MD, PhD, of Helios Klinikum Berlin-Buch, discusses the 10-year survival analysis of 3 years vs 1 year of adjuvant imatinib for patients with high-risk gastrointestinal stromal tumor. The study found that about 50% of deaths can be avoided with longer imatinib treatment (Abstract 11503).
