"Cancer Immunotherapy Boosted by Tumors with Defective Mitochondria"

Scientists have discovered that mutations in mitochondrial DNA can predict a patient’s response to immunotherapy, potentially leading to more personalized and effective cancer treatments. This groundbreaking study shows that mitochondrial DNA mutations are key indicators of a patient’s likelihood to respond to immunotherapy, revolutionizing cancer treatment approaches. The discovery opens up new ways to identify patients who could benefit most from immunotherapy by testing for mitochondrial DNA mutations, and could lead to the development of treatments that disrupt the energy sources cancer uses to spread and grow. This research has the potential to make treatment-resistant cancers sensitive to immunotherapy, allowing thousands more cancer patients to benefit from this pioneering treatment.
