How do you approach postoperative radiation for small oral cavity cancers cases with limited risk factors?
Are there situations where you skip radiation despite risk factor(s) commonly listed or do you always give adjuvant radiation?
For example, for FOM pT1N0 <4mm invasion and only risk factor being LVI?
Answer from: Radiation Oncologist at Academic Institution
LVI is considered a minor risk factor in HNC, similar to PNI, but data regarding its exact prognostic effect and whether it alone deserves adjuvant treatment are scant. For example, a large MSKCC of OC patients found LVI in only 11% of patients, compared with 25% of patients with PNI (Zaromi et al.,...

I usually don’t make exceptions, unless a patient is in very poor condition.
Answer from: Radiation Oncologist at Academic Institution
I have always approached decisions for adjuvant treatment as absolute or relative. ENE and margin issues have always been absolute, and for oral tongue, PNI to me is absolute as well, though some now are parsing extent similar to the skin where .1mm is considered concerning.
The remaining fea...
