Nadeem Riaz, MD, on Established and Emerging Biomarkers for Immunotherapy in Head and Neck Cancer
2020 Multidisciplinary Head and Neck Cancers Symposium
Nadeem Riaz, MD, of Memorial Sloan Kettering Cancer Center, discusses the biomarkers that have emerged for immunotherapy and their tumor microenvironments, from PD-L1 staining and the Combined Positive Score to next-generation genomic technologies.
Jared Weiss, MD, of the University of North Carolina, Chapel Hill, discusses outcomes for patients with stage III or IV disease who are ineligible for the standard treatment of cisplatin plus radiotherapy. His data suggest that treatment with pembrolizumab/radiotherapy instead is tolerable, with improvements seen in progression-free and overall survival (Abstract LBA1).
Jill Gilbert, MD, of Vanderbilt University Medical Center, discusses this ongoing area of investigation and which patients can safely undergo a de-intensification of treatment. Based on two randomized trials, cetuximab should not be substituted for cisplatin as a de-intensification strategy in HPV-positive oropharyngeal cancer.
Francis P. Worden, MD, of the University of Michigan Health System Comprehensive Cancer Center, explores the use of novel biomarkers that may help predict response to induction chemotherapy and survival in patients with locally advanced laryngeal cancer.
Carryn M. Anderson, MD, of the University of Iowa Hospital, discusses the investigational agent GC4419, previously shown to be safe and effective in decreasing the duration, incidence, and severity of oral mucositis in patients receiving concurrent cisplatin and radiation for oral cavity and oropharyngeal squamous cancers. The 2-year tumor outcome data suggest that GC4419 does not seem to compromise tumor control (Abstract LBA2).
Sue Sun Yom, MD, PhD, of the University of California, San Francisco, talks about the variety of evolving ways to deintensify radiation therapy, the critical need to counsel patients on the risks and benefits, and the ethical importance of respecting patient preferences in choosing their cancer therapies.
