ASCO 2026
Erika P. Hamilton, MD, FASCO, of Sarah Cannon Research Institute, talks about a comparison of the efficacy and safety of tucatinib vs placebo combined with trastuzumab and pertuzumab as maintenance therapy for HER2-positive metastatic breast cancer by stratified subgroups (Abstract 1005).

Linda R. Mileshkin, MD, MBBS, FRACP, of Peter MacCallum Cancer Centre, shares results from the phase I/IIA BLUESTAR study on the safety and efficacy of puxitatug samrotecan, a B7-H4–directed topoisomerase I inhibitor antibody-drug conjugate, in patients with endometrial cancer or ovarian cancer (Abstract 5515).

Richard Cathomas, MD, of Cantonal Hospital Graubünden, reviews results from the primary analysis of SAKK 06/19, an open-label single arm phase II trial, which found that the combination of intravesical recombinant bacillus Calmette-Guérin (BCG) with atezolizumab, cisplatin, and gemcitabine was feasible and safe without unexpected toxicities and demonstrates promising efficacy in patients with muscle-invasive bladder cancer (MIBC) (Abstract 4503).

Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, presents data from the phase III ADAM trial, a multicenter, randomized, double-blinded, placebo-controlled study of the anti–PD-L1 antibody avelumab in patients with Merkel cell carcinoma and lymph node metastases (Abstract LBA9504).

Veronica Diermayr, PhD, of EDDC and A*STAR, discusses the use of artificial intelligence (AI) driven strategy called H&E 2.0 in gastric and esophageal cancer. Researchers tested the feasibility of training deep-learning models on hematoxylin and eosin images of gastroesophageal carcinomas and their ability to predict EBC-129 antigen expression directly from these images. EBC-129 is an experimental antibody-drug conjugate that targets N256-glycosylated CEACAM5/6, which is highly expressed on solid tumors, including gastroesophageal cancers (Abstract 4018).
