Elizabeth A. Mittendorf, MD, PhD, of Dana-Farber Cancer Institute and Brigham and Women’s Hospital, summarizes a session she co-chaired on utilizing the immune system in neoadjuvant trials to treat melanoma, breast, and lung cancers.
Jacob J. Adashek, DO, of the University of South Florida and Moffitt Cancer Center, discusses data on combining immunoregulatory inhibition and targeted gene therapy, which may offer patients better outcomes (Abstract 10).
John N. Lukens, MD, of the Hospital of the University of Pennsylvania, discusses his finding that taking antibiotics within 3 months of starting treatment with immune checkpoint inhibitors may lead to inferior overall survival in patients with stage III or IV melanoma. The antibiotics were also linked to a higher incidence of severe immune-mediated colitis (Abstract 56).
Luis I. Ruffolo, MD, of the University of Rochester, discusses preclinical studies showing that semaphorin 4D blockade may sensitize pancreatic tumors to chemoimmunotherapy combinations (Abstract 26).
Christopher B. Cole, MD, PhD, of the National Cancer Institute, discusses findings from a phase I study of intraperitoneal monocytes activated by interferons alpha and gamma in patients with ovarian cancer. Two of 11 patients had a partial response and 5 of 11 had stable disease; ongoing efforts are exploring more immune system targets in order to increase efficacy (Abstract 1).
Jarrett Failing, MD, of the Mayo Clinic, discusses his study data, which show some agreement between the expression of human leukocyte antigens in primary non–small cell lung cancer with brain metastasis. His findings may have some bearing on resistance to immune checkpoint inhibitors (Abstract 43).
