Chemo-refractory NHL has a very poor outcome; the addiction of RIT to salvage regiment pre ASCT had recently demonstrated promising results.We performed a retrospective sequential study to determine the feasibility of standard Zevalin with BEAM in high-risk relapse/refractory NHL. A matched cohort analysis with a group treated with standard BEAM without Zevalin was performed as secondary endpoint. Between October 2006 and January 2013, 37 NHL patients at high risk for progression or early (< 1 year) or multiple relapses were treated with Z-BEAM and ASCT after R-DHAP or R-ICE as salvage therapy. Clinical characteristics were 19 refractory and 18 early or multiple relapse; 16 patients received 1, and 21 had 2 or more previous rituximab-containing chemotherapy. At the end of treatment, response was CR 22 (59%), PR 10 (27%), PD 4 (11%), and toxic death (TD) 1 (3%). With a median follow up of 61 months, 3-year PFS was 61% and OS 61%. Fifteen patients died, 12 of lymphoma. Comparison with 21 treated with BEAM alone showed a numerical higher 3-yr PFS rate in favor of Z-BEAM but not statistically significant (57 vs 48%). With the limitation of the small sample subgroup analysis, a significant benefit was observed in relapsed patients for PFS (78% Z-BEAM vs 22% BEAM p = 0.016) and OS (83% Z-BEAM vs 22% BEAM p = 0.001). In relapsed/refractory high-risk NHL, Z-BEAM+ASCT is able to achieve a good ORR. Three-year PFS is promising for early relapsed patients but is not satisfactory for those with refractory disease.

Autologous stem cell transplantation (ASCT) is largely employed in primary resistant or recurrent Hodgkin's Lymphoma (HL), while its role early in the course of the disease is still controversial. Our purpose was to analyse the results of 51 high-risk HL patients autografted at our Institution and the role of possible prognostic risk factors for the outcome. Twelve (23.5%) patients were in complete remission at transplant and were transplanted as having an high risk disease; 20 (39.5%) patients were in partial response and 19 (37.0%) were transplanted as primary induction failure. At a median time of 38 (6-111) months from ASCT, 36 (70.5%) patients are alive in complete remission, 8 (15.5%) patients are alive with disease and 7 (14.0%) died for progression. Thirty out of 32 (94.0%) patients transplanted with responsive disease (either complete or partial response) are alive without disease. Six out of 19 (32.0%) patients transplanted with resistant disease are alive in complete remission. The overall survival of the entire population is 77.0% at 60 (14-151) months from diagnosis. Disease free survival of the 22 patients that achieved a complete remission after ASCT (16 in partial response and 6 with resistant disease) is 100%. In our experience, more than 90% of patients transplanted with responsive but high risk disease, seem achieving and maintaining a durable complete remission, and more than 30.0% of patients submitted to ASCT with refractory disease can be potentially rescued by transplant.
