Protective regimen allows successful stem cell transplant even without close genetic match between donor and recipient

Researchers have discovered that a chemotherapy drug can improve outcomes in stem cell transplants when donors and recipients are unrelated and have significant genetic differences. The study showed comparable survival rates and lower risks of complications among patients receiving transplants with more or less extensive genetic mismat...

Black patients with acute myeloid leukemia are younger at diagnosis and experience poorer survival outcomes than White patients

Black patients with acute myeloid leukemia are diagnosed at younger ages and have worse outcomes compared to white patients, according to a study analyzing data from 10 clinical trials over 34 years.
