“…HSCT is essentially a restorative treatment: Patients are given lethal doses of chemotherapy or radiation to eliminate can-cerous cells and are then transplanted with their own or donor marrow to restore immune function. Because HSCT involves radiation and chemotherapy, followed by prolonged periods of isolation, it has been shown to be psychologically and physically challenging (see Andrykowski & McQuellon, 2004, for a review). In addition, patients receiving marrow from unrelated matched donors, as was the case in this study, compared with related donors are more susceptible to graft versus host disease (GVHD), a serious consequence of HSCT involving skin rashes, mouth and throat sores, intestinal interference, lung scarring, and liver damage.…”
