OS for patients who underwent allogeneic SCT compared with patients who did not proceed to transplantation. Patients who achieved PR or CR and proceeded to transplantation (early SCT, n = 9) were compared with patients who achieved PR or CR but did not proceed to transplantation (n = 36). Seven patients underwent SCT after relapse of CLL and subsequent salvage chemotherapy and were excluded from this analysis. We noted no improvement in median OS for patients who underwent transplantation compared with those who did not proceed to transplantation (17 vs 28 months, respectively, P = .26).
