[New data on surgical therapy from the 2021 ASCO Annual Meeting].

In addition to medical therapy studies and translational basic projects, surgically oriented studies are also regularly presented at the ASCO Annual Meeting. At the virtual conference in 2021, an US group presented a well-designed study on the de-escalation of adjuvant therapy after transoral robotic surgery of HPV-positive oropharyngeal cancer. Furthermore, the results of an Italian group on induction therapy for resectable sinunasal carcinomas were presented. An ongoing multicenter study on the surgical treatment of early-stage oral cavity cancer will investigate the impact of sentinel lymph node biopsy compared to elective neck dissection. In addition to these presentations, the following review article summarizes other studies in which surgical therapy was part of the investigational workflow.
