Inclusion Criteria: 1. Hematological malignancies confirmed histologically and not rapidly progressing: * Acute myeloid leukemia (AML) in complete remission (CR) (defined as ≤ 5% marrow blasts and absence of blasts in the peripheral blood); * Myelodysplastic syndromes (MDS) with ≤ 5% marrow blasts and absence of blasts in the peripheral blood; * Chronic myeloid leukemia (CML) in chronic phase (CP); * Myeloproliferative neoplasms not in blast crisis and not with extensive marrow fibrosis; * Acute lymphoid leukemia (ALL)in CR; * Multiple myeloma not rapidly progressing; * chronic lymphocytic leukemia (CLL); * Non-Hodgkin's lymphoma (aggressive NHL should have chemosensitive disease); * Hodgkin's disease with chemosensitive disease; 2. 10/10 HLA-A, -B, -C, DRB1 and DQBI allele-matched donor fit to/willing to donate PBSC. 3. Clinical situations: 1. Theoretical indication for a standard allotransplant, but not feasible because: * Age \> 50 yrs; * Unacceptable end organ performance; * At the physician's decision; * Patient's refusal. 2. Indication for a standard auto-transplant: perform mini-allotransplantation 2-6 months after standard autotransplant. 4. Other inclusion criteria: * Male or female; fertile patients must use a reliable contraception method; * Age ≤ 75 yrs (children of any age are allowed in the protocol); * Informed consent given by patient or his/her guardian if of minor age.
