Brief summary: The aim of this study is rate of acute graft-versus-host disease II-IV measured at day +365according to conventional criteria (Przepiorka et al. 1995) in patients with high risk non-Hodgkin lymphoma B subjects with Allogeneic Stem Cell Transplant

Detailed description: In addition to above:

* Rate of progression-free survival (PFS) at 12, 24, 36 and 60 months post-transplant defined as the time between the infusion of progenitors and the disease progression or death. Patients alive or in complete remission will be censored at the time of last follow up
* Transplant-related mortality (TRM) at 12, 24, 36 and 60 months after transplantation, defined as any death not caused directly by lymphoma (any death caused by complications related to transplantation).
* Overall survival (OS) defined as the time between infusion of progenitors and the patient's death from any cause. Alive Patients will be censored at the time of last follow-up
* Incidence of chronic graft versus host disease (GVHD) wide at 1 and 5 years according to conventional criteria (Atkinson et al. 1989) and Filipovich et al. (BBMT, 2005).
* Rate of event-free survival (DFS) defined as time interval between diagnosis of lymphoma and lymphoma progression or relapse or death if the above does not occur.
* Successful graft implantation: is defined as:

  1. º: three consecutive days with absolute neutrophil count greater than 0.5 \* 109 / L
  2. ° thrombocythemia exceeds 20 \* 109 / L.
* Reconstitution of the immune system: lymphocyte count populations CD20, CD3, CD4 and CD8 and immunoglobulinemia serum (days +100, 180, 360, 18 months and 24 months).
* intercurrent infections. All sorts of infections (viral, fungal and bacterial)will be recorded
* Safety assessment by the standards of Common Terminology Criteria for adverse events v. 4.0

Eligibility criteria: Inclusion Criteria:

1. Subjects who have given their informed consent before any study-specific procedures
2. Histopathological diagnostic of NHL cell B CD 20 + B of different histologic subtypes:
3. High risk CD +20 Lymphoma having at least one of the following characteristics:

   * Less than a partial remission after two courses of treatment
   * Relapse after autologous peripheral blood stem cell (PBSCT)
   * Evidence of measurable disease (With CT and PET or PET / CT) three months after PBSCT
   * Hematopoietic precursors improper count in patients with relapsed or partial remission after two treatment lines that prevent the realization of a PBSCT.
   * Patients after first relapse in RP after two lines of treatment in whom the probability of freedom from progression per year is very low due to risk factors such as: first CR less than 12 months after PBSCT low SLP, etc..
4. Age between 18 and 65 years
5. ECOG between 0 to 1 (Appendix III).
6. Subjects who are HBgAG negative, anti-HBc positive and HBV DNA negative may be include in the study but must undergo HBV DNA monitoring
7. Adequate lung Function

9. Adequate renal and hepatic function defined by the following biochemical parameters
10. The disease status prior to transplantation had to be in place in accordance with the criteria of Revised Response Criteria for Malignant Lymphoma, Cheson 2007. CT and PET or PET / CT.
11. Availability of a histocompatible donor (9 to 10/10 loci) family or unrelated
12. Adults with ability to procreate must commit to use an effective method of birth control during the study treatment and at least 6 months.

Exclusion Criteria:

7. Treatment with any marketed or experimental drug administered not in a period between 5 terminal half-lives of clearance of therapy or 4 weeks before enrollment
8. Participation in another interventional clinical trial.
9. Prior treatment with anti-CD20 monoclonal antibody or alemtuzumab within 3 months prior to start of therapy. This is generally required and may be excluded as applicable.
