V.1.2. Clinical situations * Theoretical indication for a standard allo-transplant, but not feasible because: * Age \> 55 yrs; * Unacceptable end organ performance; * Patient's refusal. * Indication for a standard auto-transplant: perform mini-allotransplantation 2-6 months after standard autotransplant. V.1.3. Other inclusion criteria * Male or female; fertile female patients must use a reliable contraception method; * Age \< 75 yrs. * Informed consent given by patient or his/her guardian if of minor age.
