Emily Z. Keung, MD, of The University of Texas MD Anderson Cancer Center, discusses the complex interactions of immune infiltrates and neoadjuvant immune checkpoint blockade (ICB) in patients with resectable soft-tissue sarcoma. These interactions may hold the key to understanding pathologic response to ICB and ICB resistance (Abstract 379).
Hannah E. Dzimitrowicz, MD, of Duke Cancer Center, discusses study results showing that in patients with melanoma and renal cell cancer receiving immune checkpoint inhibitor therapy, the COVID-19 vaccination appears to be well tolerated and safe. A higher rate of post-vaccination symptoms reported in these patients is likely related to more frequent visits compared with controls (Abstract 625).
Kim A. Reiss, MD, of the University of Pennsylvania, discusses results of a phase I trial of a CAR-M engineered macrophage cancer therapy, known as CT-0508, for patients with solid tumors that overexpress HER2. CAR-M, designed to exploit the natural role of macrophages to initiate an antitumor response, is currently under study at multiple clinical sites (Abstract 951).
Mehmet Altan, MD, of The University of Texas MD Anderson Cancer Center, discusses findings from a phase Ib dose-escalation study, which showed early evidence of activity for NKTR-255, an investigational IL-15 receptor agonist, plus cetuximab in patients with solid tumors. Treatment appeared to lead to expansion and proliferation of NK and CD8+ cells (Abstract 957).
Yevgeniy R. Semenov, MD, of Massachusetts General Hospital and Harvard Medical School, discusses new findings suggesting cutaneous adverse events such as vitiligo, lichenoid dermatitis, and psoriasis—which often occur in patients with cancer who receive immune checkpoint inhibitors—may be strongly associated with response to therapy and a 22% reduction in mortality (Abstract 814).
Patrick Hwu, MD, of Moffitt Cancer Center and President of the Society for Immunotherapy of Cancer (SITC), and Mary Dean, JD, CAE, SITC Executive Director, discuss the organization’s mission, strides made in cancer immunology, meeting the challenge of immunoresistance, and the new SITC app for clinical practice guidelines. This app places a useful tool in the hands of health-care providers, one that can be continually updated as the science evolves.
