What dose would you use for re-irradiation of metastatic melanoma to an inguinal node?
If the inguinal node was previously treated with SBRT 30Gy/5fx and immunotherapy >6 months, what treatment would you recommend?
Answer from: Radiation Oncologist at Community Practice
For melanoma, I have used 27 Gy in 3 fractions of 9 Gy, one week apart, for an unresectable tumor near the eye in an elderly patient. The patient was on concurrent nivolumab and remains NED 3 yrs out.
I think that the inguinal area could tolerate this dose if it has been 6 months since prior course...
