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.
