Data from the 2022 ASCO Annual Meeting on surgical therapy

Abstract

Last year, studies on immuno-oncologic treatment approaches for recurrent or metastatic head and neck cancer were the main focus at the two major international cancer congresses of the American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO). The success of these therapeutic strategies has led to many new studies, including their use in the neoadjuvant setting. This review article summarizes presented studies from ASCO 2022 in which surgical therapy is the focus of the study protocol and also includes study results on neoadjuvant treatment strategies. No surgical trials were presented at ESMO 2022. At ASCO 2022 as well as in previous years, it became increasingly clear that treatment de-escalation in the context of human papillomavirus (HPV)-associated oropharyngeal carcinoma treatment involving surgical measures appears to be oncologically safe and functionally beneficial. In addition, anumber of studies indicate that in the setting of neoadjuvant administration of immuno-oncologic agents, aproportion of patients have pathologic complete remission. In this fraction of patients, which is usually significantly smaller than 50%, survival data are better than in those who have already failed to respond to neoadjuvant therapy. Unfortunately, however, significant toxicities or tumor progression with the risk of inoperability were also seen under these current therapeutic regimens, leading to discontinuation of therapy in 5-20% of cases. It remains to be seen whether neoadjuvancy with immune checkpoint inhibitors can establish itself, in contrast to the failed attempts of the past with the use of cytostatics.
