Study Arms:
- Cohort A (Type: None): In Cohort A, patients will be included either in the group sustainable responseor in the short / refractory response group.~- sustainable response group : patient with NHL diffuse large B cells, and persistent complete response for at least 6 months after first-line treatment with Rituximab OR patient with follicular NHL, mantle NHL, NHL marginal zone or Waldenstrom's disease in complete response or partial stable response for at least 1 year after first line treatment with Rituximab~short / refractory response group : patient with NHL diffuse large B cells, refractory or relapsed in less than 6 months after at least one line of treatment with Rituximab OR patient with follicular NHL, mantle NHL, NHL marginal zone or Waldenstrom's disease refractory or relapsed / progression within less than 1 year after at least one line of treatment with Rituximab
- Cohort B (Type: None): For Cohort B patients will be included either in the group B hematologic therapeutic abstention or in the group any blood disease not treated with anti-CD20 antibodies.~B hematologic therapeutic abstention group : patient with hematological malignancy whatever the initial expansion stage~any blood disease not treated with anti-CD20 antibodies group : patient with follicular NHL, mantle NHL, NHL marginal zone or Waldenstorm disease without treatment criteria at diagnosis and with stable disease for at least 6 months
