Imaging considerations for salvage surgery in nasopharyngeal carcinoma: what surgeons need to know

Abstract

Nasopharyngeal carcinoma is frequently an undifferentiated squamous cell carcinoma, which is primarily treated with radiotherapy with or without chemotherapy; however, for residual or recurrent cancer, salvage surgery is the treatment of choice for resectable disease because it reduces the significant morbidity associated with re-irradiation. This review highlights the current surgical approach, mapping the extent of disease with an emphasis on magnetic resonance imaging (MRI) and integrated positron-emission tomography (PET)/computed tomography (CT), imaging features that determine operability for nasopharyngectomy and neck dissection, and need for a succinct radiological report and multidisciplinary team discussion, which are of paramount importance for successful surgical planning.
