Analysis of rare periparotid recurrence after parotid gland-sparing intensity-modulated radiotherapy for nasopharyngeal carcinoma.

CONCLUSION: Periparotid recurrences are rare after definitive IMRT for nasopharyngeal carcinoma. However, patients with ipsilateral retropharyngeal lymph nodes or level II nodal extracapsular spread on pretreatment MRI could be suspicious of metastatic periparotid nodules. Distant metastases were the main treatment failure despite a combination of several salvage treatment of periparotid recurrence. More effective chemotherapy should be explored.
