New study results being presented at the American Society of Clinical Oncology's annual meeting in Chicago found that the PD-1 and PD-L1 biomarkers can be used to determine response and resistance, explained Daniel P. Petrylak, MD, professor of medicine (medical oncology) and of urology at the Yale Cancer Center. He will be presenting the results of a trial on PD-1 and PD-L1 expression in bladder cancer.

"We need to diligently assess tissue in these patients to help understand the marker pattern and how it can be used to treat them," he said.
