Is there a role for DDR gene mutation or tumor mutation burden/load in predicting response to immunotherapy in urothelial cancer?

Our recent work showed that urothelial cancers harbor high rate of alterations in DDR (DNA damage repair and response) genes, with 25 – 29% rate of deleterious alterations and up to 25% with variants of unknown significance – considering the genomic complexity of urothelial cancers, it is not un...
