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).
Michael S. Hofman, MBBS, of the Peter MacCallum Cancer Centre, discusses phase II results from the ANZUP 1603 trial, which showed that in men with docetaxel-treated metastatic castration-resistant prostate cancer, LuPSMA was more active than cabazitaxel, with relatively fewer grade 3 and 4 adverse events and a more favorable PSA progression-free-survival (Abstract 5500).
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).
Meletios A. Dimopoulos, MD, of the University of Athens, discusses phase III results from the BOSTON trial, which showed that once-weekly selinexor, bortezomib, and dexamethasone significantly improved progression-free survival and overall response rates compared with twice-weekly bortezomib and dexamethasone in patients previously treated for multiple myeloma (Abstract 8501).
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).
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).
