Revlimid Dose 25 mg in Association With (R-CHOP) in the Treatment Follicular Lymphoma

The purpose of the study is to assess the efficacy of the association of Lenalidomide (Revlimid) and R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, vincristine and Prednisone) in a population of patients with follicular lymphoma as measured by the response rate at the end of treatment.

Men must be counseled at a minimum of every 4 weeks about pregnancy precautions and risks of fetal exposure.
* All subjects must abstain from donating blood while taking study drug therapy and for one week following discontinuation of study drug therapy.
* Agree not to share study drug with another person and to return all unused study drug to the investigator.

  * A female patient is considered to have childbearing potential unless she meets at least one of the following criteria 1) Age ≥ 50 years and naturally amenorrhoeic for ≥ 1 year (amenorrhoea following cancer therapy does not rule out childbearing potential); or 2) Premature ovarian failure confirmed by a specialist gynaecologist or 3) Previous bilateral salpingo-oophorectomy (BSO), or hysterectomy, or 4) XY genotype, turner syndrome, uterine agenesis.

Exclusion Criteria:
