Reduced Intensity Allogeneic HCT in Advanced Hematologic Malignancies w/T-Cell Depleted Graft
Recruiting
Reduced intensity conditioning (RIC) has emerged and been increasingly adopted as a modality to allow preparative conditioning pre transplant to be tolerated by older adults or those patients that are otherwise unfit for myeloablative conditioning. In this study, we aim to use RIC followed by matched related/unrelated donor, 7/8 matched related/unrelated donor, or haploidentical donor peripheral blood stem cell transplantation. Standard strategies to control the alloreactivity following HCT util... Read More

Women Informed to Screen Depending on Measures of Risk (Wisdom Study)
Recruiting
Most physicians still use a one-size-fits-all approach to breast screening in which all women, regardless of their personal history, family history or genetics (except BRCA carriers) are recommended to have annual mammograms starting at age 40. Mammograms benefit women by detecting cancers early when they are easier to treat, but they are not perfect. Recent news stories have discussed some of the potential harms: large numbers of positive results that cause stressful recalls for additional mamm... Read More
