ALLOGENEIC HEMATOPOIETIC CELL TRANSPLANTATION FOR MYCOSIS FUNGOIDES AND SEZARY SYNDROME

摘要

We describe outcomes after allogeneic hematopoietic cell transplantation (HCT) for mycosis fungoides and sezary syndrome (MF/SS). Outcomes of 129 subjects with MF/SS reported to the Center for the International Blood and Marrow Transplant (CIBMTR) from 2000–2009. Median time from diagnosis to transplant was 30 (4–206) months and most subjects were with multiply relapsed/refractory disease. Majority (64%) received non-myeloablative conditioning (NST) or reduced intensity conditioning (RIC). NST/RIC recipients were older in age compared to myeloablative recipients (median age 51 vs. 44 y p= 0.005) and transplanted in recent years. Non-relapse mortality (NRM) at 1 and 5 years was 19% (95 % CI 12–27%) and 22% (95 % CI 15–31%) respectively. Risk of disease progression was 50% (95% CI 41–60%) at 1 year and 61% (95% CI 50–71%) at 5 years. Progression free survival (PFS) at 1 and 5 years was 31% (95% CI 22–40%) and 17% (95% CI 9–26%) respectively. Overall survival at 1 and 5 years was 54% (95% CI 45–63%) and 32% (95% CI 22–44%) respectively. Allogeneic HCT in MF/SS results in 5 year survival in approximately one-third of patients and of those, half of them remain disease-free.
