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).
Sarah A. Holstein, MD, PhD, of the University of Nebraska Medical Center, discusses top myeloma abstracts from the ASCO20 Virtual Scientific Program: the ENDURANCE trial on carfilzomib, lenalidomide, dexamethasone, and bortezomib; the STaMINA study on transplantation strategies; a first-in-human study on the novel CELMoD agent CC-92480 plus dexamethasone; the CARTITUDE-1 trial on CAR T-cell therapy; and a phase I study of teclistamab (Abstracts LBA3, 8506, 8500, 8505, and 100).
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).
Douglas B. Johnson, MD, of Vanderbilt University Medical Center, discusses three important melanoma abstracts: the need for more than two doses of nivolumab plus ipilimumab in combination immunotherapy; antitumor activity for low-dose ipilimumab with pembrolizumab after disease progression on PD-1 antibodies; and ipilimumab alone or in combination with anti–PD-1 therapy for metastatic disease resistant to PD-1 monotherapy (Abstracts 10003, 10004, and 10005).
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).
Roy S. Herbst, MD, PhD, of Yale Cancer Center, discusses data from the ADAURA study, which showed that compared with placebo, osimertinib as adjuvant therapy after complete tumor resection reduced the risk of disease recurrence or death by 79% in patients with non–small cell lung cancer (Abstract LBA5).
