The laboratory’s translational studies are concentrated on enhancing anti-tumor immunity through improved myeloid cell function and cytolytic T cell activity within renal cell carcinoma. Our laboratory’s findings from a pilot trial in metastatic renal cell carcinoma combining high-dose radiation of kidney tumors with surgical resection, provide a glimpse into the immune activating effects of radiation in human cancer. The laboratory’s most recent studies performed in collaboration with Dr. Scott Abrams shed light on the role key transcription factors at play in macrophage behavior and patient outcome.

Little is known about how radiation therapy to kill cancer cells affects immune cells and other components of patient tumors. But a study out of Roswell Park Comprehensive Cancer Center is shedding light on that process, providing information that could be key for planning treatment regimens that combine immunotherapy and radiation therapy. The authors outline their findings in a new study in the Journal for ImmunoTherapy of Cancer.
