In the intention to treat analysis, the 1 year RFS was 70% (historic control 50%). 2 of 3 pts with BRAF V600E mutations have had early recurrences. 2 pts had VCAN high tumors and both recurred prior to 1 year....The combination of SBRT with Pem and surgical resection is well tolerated with no signal of increased immunotherapy-related toxicity and preliminary evidence of potential enhanced efficacy.
