Opened in the spring of 2008, a new outpatient clinic within Memorial Hospital is enabling Memorial Sloan-Kettering's adult allogeneic bone marrow transplant (BMT) service to enhance comfort and convenience for a rapidly growing patient population.
"With this new facility, we are able to care for more transplant patients in a calming environment, improving their well-being while greatly reducing wait times," said James W. Young, Interim Chief of the Adult BMT Service. "The outpatient clinic provides, in a single location, the follow-up treatments that patients need after they have received their transplants."
Memorial Sloan-Kettering Cancer Center has been a leader in bone marrow transplantation as a treatment for cancer since Center physicians performed the first successful transplant from an unrelated donor in 1973. Such transplants, from one person to another, are called allogeneic. This type of transplant uses cells obtained from a donor -- either a family member or someone unrelated -- whose tissue type closely matches that of the recipient. Today, the Adult BMT Service more commonly performs allogeneic transplants using blood stem cells rather than marrow. The service also does allogeneic transplants using stem cells from umbilical cord blood. (Autologous transplantation, in which a patient's own cells are used, is also performed at Memorial Sloan-Kettering but by another service.)
Demand for transplants has surged at Memorial Sloan-Kettering in recent years because, Dr. Young explained, the treatment benefits people with a variety of cancerous and noncancerous diseases. There also are more varied ways of performing transplants, as the field has expanded to treat diseases common in older patients. Finally, more people are eligible for allogeneic transplants from unrelated donors due to improvements in matching tissue types. As a result, the number of adult patients receiving allogeneic transplants at Memorial Sloan-Kettering jumped from 58 in 2004 to nearly 120 projected for 2008.
Allogeneic stem cell transplantation patients typically remain in the hospital for several weeks following the transplant. After they are discharged, they require extensive, specialized care that may include blood transfusions, intravenous drugs, and respiratory treatments. Before the new outpatient clinic opened, patients received these treatments in the Adult Day Hospital, sharing the space with patients being seen for other types of cancer. As the number of transplant patients increased, the logistics of accommodating all their treatment needs became a challenge.
