A new approach demonstrated that the recognition of unique cancer mutations appeared to be responsible for complete cancer regressions in two metastatic melanoma patients treated with a type of immunotherapy called adoptive T-cell therapy. This new approach may help develop more effective cancer immunotherapies, according to a study published in Clinical Cancer Research, a journal of the American Association for Cancer Research.
“This study provides the technical solution to identify mutated tumor targets that can stimulate immune responses, which is one of the major bottlenecks in developing a new generation of adoptive T-cell therapy,” said Steven A. Rosenberg, MD, PhD, chief of surgery at the National Cancer Institute (NCI) in Bethesda, Maryland. “The two targets identified in this study play important roles in cancer cell proliferation.
