Dear Dr. MP,
Thank you for your question and interest.
Mucoepidermoid carcinoma has a broad spectrum of aggressiveness, from low grade tumors that primarily cause local problems to high grade tumors that unfortunately can have a very low survival rate. The most important prognosticators are age, tumor size and histology (high mitotic figures, neural involvement, necrosis, and anaplasia).
The indications for radiation therapy for mucoepidermoid carcinoma of the parotid are:
In addition to external beam radiation alone, intraoperative brachytherapy plus postoperative external beam radiation is also used to improve local control. A consultation from a radiation oncologist is warranted in this case.
