Lung Cancer Gains, Alzheimer's Genetics, and Chemo-Free Breast Cancer

Today's briefing covers a major survival gain in small cell lung cancer, the largest Alzheimer's genetics study to date, and five year results on skipping chemotherapy in HER2 positive breast cancer. We also look at updated stroke thrombolysis guidance, a negative trial of community health workers for diabetes prevention, and a CAR T cell therapy complication. Plus a quick rundown of several more studies in tumor immunology and liver disease.
