Impact of previous high-dose therapy on outcome after allografting for multiple myeloma.
We describe a single centre experience of 33 patients allografted for multiple myeloma, of which 28 received matched sibling marrow, one haploidentical family donor marrow and four matched but unrelated donor marrow. Median follow-up after transplant is 27 months, and 13 patients are currently alive. One out of four patients with an unrelated donor survives and 12 out of 28 (42.8%) with matched sibling donors. Four patients were unevaluable because of early death (<day 21), and one patient experienced graft failure. The probability of overall survival is 35.7 % at 3 years. The probability of disease-free survival is 39% at 3 years, and the probability of treatment-related mortality is 54% at 1 year. Acute GVHD developed in 26 (78.8%) patients and was responsible for six deaths. Twenty-four patients (72.7%) developed renal dysfunction and 22 (66.7%) developed hepatic dysfunction. Seventeen patients (51.5%) died of transplant-related problems in the first 150 days, and one at 6 months. Among the 13 survivors, none has experienced disease progression at a median follow-up of 27 months (range 3-65 months). We conclude that since allogeneic bone marrow transplantation is the only potentially curative option in myeloma, it should be offered to younger patients early in the course of their disease, when procedure-related morbidity and mortality are likely to be at their lowest.
