RESUMO

Hematological malignancies in Jehovah's Witnesses are often difficult to cure since these patients deny transfusions. By a retrospective analysis, we report the possibility of treating some tumors, mostly hematological, with either autologous or allogeneic bone marrow transplantation (BMT) without blood support. Eight patients were evaluated, including lymphoma (two patients), acute lymphoblastic (one patient) and myeloblastic (one patient) leukemia, chronic lymphocytic leukemia (one patient), refractory anemia with blasts in transformation (one patient), chronic myeloid leukemia (one patient) and metastatic breast cancer (one patient). All patients experienced a severe cytopenia with no major side effects or life-threatening complications. We had four deaths: three from relapse and progression of the disease (at 5, 8 and 15 months after the stem cell infusion), and one from acute intestinal GVHD (at 2 months after the stem cell infusion). Four patients are in complete clinical remission (at 8, 10, 16 and 26 months after the stem cell infusion), and this was related to the disease outcome. We conclude that autologous and allogeneic BMT are feasible without the support of transfusions. We believe that this should be performed as soon as possible in the course of the disease.

RESUMO

An interim report evaluating the feasibility of myeloablative therapy followed by peripheral blood stem cell (PBSC) autotransplant in patients aged >60 years is presented. In the last 2 years 19 patients >60 years old with several oncological conditions, mostly hematological, underwent PBSC autotransplant either as salvage therapy following relapse or resistance to conventional treatment, or as consolidating therapy as a part of a well defined protocol. There were 13 males and six females; the mean age was 66.9 years (range 61-76 years); nine patients had resistant or relapsed lymphoma, six myeloma, two acute leukemia, one Waldenstrom's disease and one lung cancer. Myeloablative schemes included BEAM exclusively for lymphomas, busulfan and melphalan (Bu-MPH) mainly for myeloma, busulfan and cyclophosphamide (Bu-CTX) for lymphomas and leukemia and VP-16 and CTX for lung cancer. Mobilization of CD34+ cells was achieved in all patients with the combination of high-dose CTX and G-CSF with collections between 2.83 to 19.04 x 10(6)/kg (mean 7.1). All patients engrafted with a median time for recovery of PMN (>0.5 x 10(3)/microl) of 10 days (range 8-12 days) and for PLT (>20 x 10(3)/microl) of 12 days (range 10-17 days). Major responses were obtained in 15 of 16 patients evaluable for response and eight patients entered CR; overall eight patients are in CR, five are alive with disease, five are dead from disease progression and one is dead because of congestive heart failure 7 months following PBSC autotransplant. No early deaths following the procedure occurred; major side-effects were grade I-II mucositis (58%), fever with documented sepsis (10%), pneumonia (5%), cardiac, renal and liver toxicity (5%). Cardiac function was evaluated before and after myeloablative therapy by VEF in all patients; no significant modifications were necessary. In conclusion, our experience demonstrates that myeloablative therapies in older selected patients can be feasible; the feasibility of introducing PBSC autotransplantation following myeloablative therapy as a front-line treatment in patients aged >60 years, needs accurate guide lines for selection of appropriate patients.
