How do you treat a low grade mucoepidermoid carcinoma with unkown primary site?

If pathology review is done and all imaging scans including CT scan, PET scan and MRI have come back without a primary site, is it reasonable to closely follow or would you treat with adjuvant RT to the neck +\- potential primary sites?

Answer from: Radiation Oncologist at Academic Institution

A misnomer. Low grade MECs don’t metastasize so, if it does, it’s not low grade regardless of the histology. Neck dissection plus postop RT and include the potential primary site if feasible.
