LOS ANGELES (Jan. 20, 2026) — For the sixth consecutive year, Cedars-Sinai patients who receive donor stem cell transplants for blood cancers like leukemia have significantly better survival outcomes than patients treated at most other institutions.
These outcomes place the medical center at the top of rankings recently released by the Center for International Bone and Marrow Transplant Research (CIBMTR). Cedars-Sinai is one of just seven adult transplant centers out of 176 in the U.S. where patient survival after transplant is significantly better than predicted.
“We have a carefully chosen approach to pretransplant conditioning and graft-versus-host disease prevention for our patients, which plays a vital role in our strong survival outcomes,” said John Chute, MD, director of the Division of Hematology and Cellular Therapy at Cedars-Sinai Cancer. “We also have a dedicated system for keeping patients in touch with their care team, which helps identify problems before they become serious.”
The greatest risk to stem cell transplant patients is during the first 100 days after transplant, said Ronald Paquette, MD, clinical director of the Stem Cell and Bone Marrow Transplant Program at Cedars-Sinai Cancer.
“We have modified our pretransplant regimens and post-transplant care to minimize toxicity to the patients and give them the best chance for a successful recovery,” Paquette said. “We also are careful to select stem cell donors who can provide the best-quality stem cell and immune cell recovery.”
An allogeneic transplant uses stem cells from a donor, rather than the patient’s own cells, and Paquette said the approaches to these transplants are specific to each institution.
Along with a uniform approach to pretransplant therapy, Chute and Paquette attributed Cedars-Sinai’s top ranking to the frequent use of younger half-matched donors—often a child or grandchild of the patient—to get patients to transplant more quickly.
“In addition to that, there is no replacement for the people who take care of the patients, from the transplant coordinators to the physicians, nurses and advanced practice providers,” Chute said. “The dedication of our team provides that crucial element that yields the best possible results for our patients.”
Chute and Paquette are currently exploring stem cell transplant for patients who would once have been thought “too old” for the procedure.
“Age 75 used to be the upper limit, but that was arbitrary,” Paquette said. “We have transplanted several patients over age 75 and all are doing well so far. We are hoping to learn more about the biology of transplant via these patients, to learn about the pluses and minuses of doing transplants in patients this age. We want to learn not only how to extend their survival but also how to maximize their quality of life.”
