Two women with recurrent breast cancer presenting with myelodysplastic syndrome (refractory anemia) during chemotherapy were reported. At diagnosis of myelodysplastic syndrome, white blood cell count, hemoglobin and platelet count were 3,300/mm3, 4600/mm3, 5.5 g/dl, 6.3 g/dl, 1.1 x 10(4)/mm3 and 6.8 x 10(4)/mm3, respectively, in case 1 and 2. Bone marrow taps showed hypercellular marrows with dysplastic changes of erythrocytes, granulocytes and megakaryocytes in both cases. Before the occurrence of the myelodysplastic syndrome, both patients received various cytotoxic agents (mitomycin C: 77 mg, 108 mg; cyclophosphamide: 34,400 mg, 40,000 mg; doxorubicin: 340 mg, 460 mg; methotrexate: 410 mg, 700 mg; and vincristine: 9.5 mg, 14 mg, in case 1 and 2, respectively). One patient died 2 months after the onset of the myelodysplastic syndrome, and the other died 3 months after due to progression of metastatic breast cancer. Risk-benefits analysis of chemotherapy, especially adjuvant chemotherapy, should be performed in cases of breast cancer.

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.
