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).
Thierry André, MD, of Hôpital Saint-Antoine, discusses the phase III results from KEYNOTE-177, which showed that, compared with standard chemotherapy of FOLFOX or FOLFIRI, pembrolizumab doubled median progression-free survival, from 8.2 months to 16.5 months, in patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract LBA4).
Farhad Ravandi-Kashani, MD, of The University of Texas MD Anderson Cancer Center, discusses updates from a phase I dose-escalation study of AMG 330, a bispecific T-cell engager molecule. It showed early evidence of an acceptable safety profile, drug tolerability, and antileukemic activity, supporting further dose escalation in patients with acute myeloid leukemia (Abstract 7508).
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).
Tingyan Shi, MD, PhD, of Zhongshan Hospital, Fudan University, discusses study results that showed secondary cytoreductive surgery in selected patients extended progression-free survival and might contribute to long-term survival (Abstract 6001).
Merry-Jennifer Markham, MD, ASCO’s Cancer Communications Chair, gives her views on key papers presented at the ASCO20 Virtual Scientific Program, addressing gynecologic malignancies and COVID-19.
