Alberto F. Sobrero, MD, of the Ospedale San Martino, discusses final results of the IDEA study, which supported the use of 3 months of adjuvant CAPOX, vs 6 months, for most patients with stage III colon cancer. The shorter treatment duration reduced toxicity, inconvenience, and cost (Abstract 4004).
Michael J. Morris, MD, of Memorial Sloan Kettering Cancer Center, discusses phase III data from the CONDOR trial, which showed that PSMA-targeted PET scans detected and localized occult disease in most men with biochemically recurrent prostate cancer presenting with negative or equivocal conventional imaging findings (Abstract 5501).
Andres Poveda, MD, of Initia Oncology, discusses phase III results from the SOLO2 trial, which showed that, compared with placebo, maintenance olaparib improved median overall survival by 12.9 months in patients with platinum-sensitive, relapsed ovarian cancer and a BRCA mutation (Abstract 6002).
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).
Egbert F. Smit, MD, PhD, of the Netherlands Cancer Institute, discusses interim results from the DESTINY-Lung01 trial of fam-trastuzumab deruxtecan in patients with HER2-mutated metastatic non–small cell lung cancer. The data show clinical activity with high overall response rates and durable responses (Abstract 9504).
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).
