How do you decide on the elective radiation volume when treating a lateralized node negative non-tongue oral cavity cancer with definitive chemoRT?
E.g. buccal mucosa, maxillary vestibule tumors
Particularly what do you levels of the contralateral neck do you include?
What factors (T stage, grade, location etc.) would affect your decision?
Answer from: Radiation Oncologist at Academic Institution
I recommend surgery with/without postop RT unless medically inoperable. With curative intent, use brachytherapy or intraoral cone for the boost to shorten the overall time. Irradiate contralateral neck if within 1.5-2 cm of midline.
