Transoral robotic surgery for carcinoma of unknown primary in the head and neck.

ABSTRACT

Multiple diagnostic and treatment paradigms exist for the management of carcinoma of unknown primary (CUP) metastatic to cervical lymph nodes. Transoral robotic surgery (TORS) has emerged as a modality for diagnosis and treatment of CUP, optimizing identification and resection of the primary tumor, although also preventing chemotherapy in a subset of patients. This article presents the authors' treatment paradigm and reviews the literature supporting the use of TORS in the management of CUP.
