Postoperative radiotherapy to the neck for pN1 status HNSCC patients after neck dissection.

ABSTRACT: The significance of postoperative radiotherapy (PORT) to the neck for pN1 status head and neck squamous cell carcinomas (HNSCC) after neck dissection is unclear. A total of 208 patients with pN1 status HNSCC treated from January 1, 2001, to December 31, 2014, were enrolled in the current study. The 5-year regional recurrence-free survival (RRFS), overall survival (OS) and distant metastasis-free survival (DMFS) were compared between patients with or without PORT to the dissected neck. Moreover, the stratified Cox proportional hazards models were used to assess the association between PORT to the neck and survival before and after propensity score matching. Seventy-nine patients received PORT to the neck, while 129 did not. All patients were followed for over 5 years, with a median follow-u
