Radiation therapy (RT) consensus contouring guidelines in the postoperative setting for complex cutaneous squamous cell carcinoma of the head and neck have been developed by expert clinicians in the field of head and neck and dermato-oncology and members of the Head and Neck Cancer International Group to assist radiation oncologists involved in the management of this disease. These guidelines present a set of principles used to define postoperative RT volumes and corresponding minimum doses after resection of all macroscopic tumor with or without microscopic residual disease. It is anticipated they will promote the harmonization of postoperative RT globally and contribute to a reduction in treatment variation among clinicians, allowing for RT quality and outcomes assessment across institutions.

The speed and scale of the global COVID-19 pandemic has resulted in unprecedented pressures on health services worldwide, requiring new methods of service delivery during the health crisis. In the setting of severe resource constraint and high risk of infection to patients and clinicians, there is an urgent need to identify consensus statements on head and neck surgical oncology practice. We completed a modified Delphi consensus process of three rounds with 40 international experts in head and neck cancer surgical, radiation, and medical oncology, representing 35 international professional societies and national clinical trial groups. Endorsed by 39 societies and professional bodies, these consensus practice recommendations aim to decrease inconsistency of practice, reduce uncertainty in care, and provide reassurance for clinicians worldwide for head and neck surgical oncology in the context of the COVID-19 pandemic and in the setting of acute severe resource constraint and high risk of infection to patients and staff.
