Treatment of persistent/recurrent nodal disease in nasopharyngeal cancer

pa.ythelady61 shared this article with you from Inoreader Treatment of persistent/recurrent nodal disease in nasopharyngeal cancer Via Current Opinion in Otolaryngology & Head and Neck Surgery - Published Ahead-of-Print Purpose of review Persistent or recurrent disease in the neck lymphatics is an unusual pattern of failure in nasopharyngeal carcinoma (NPC) after definitive radiotherapy or chemoradiotherapy. The purpose of this review is to critically synthesize the current knowledge regarding salvage treatment of this unique form of failure in NPC. Recent findings Surgery in the form of radical neck dissection has been established as the standard salvage treatment with 5-year regional control of 60--86%. Recent shift in paradigm has resulted in the use of modified or selective neck dissection as salvage surgery in some centers. Risk factors for poor survival outcome include recurrent nodal disease, number of involved lymph nodes, extracapsular extension, high lymph node ratio, and positive resection margin. There are no well controlled studies on the role of additional radiotherapy or chemotherapy to improve local control or survival after salvage neck dissection in this group of patients with regional failure. Summary There is limited literature regarding the extent of surgical dissection in treating nodal persistent or recurrent disease. Prospective studies are also needed to determine whether adjuvant therapy improves treatment outcomes.
