What dose would you use to treat unresectable basal cell carcinoma of the vulva?

I would make sure not mixed pathology like basosquamous.

If pure basal then would treat primary alone with dose and volume like BCC of skin.

I have treated one patient with 55 Gy in 20 Fx who is NED at 3 years post-RT. Had some acute RT toxicities similar to most vulvar cancers.

Treated gross disease alone with small margin, as mentioned above.
