Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.~Arm D (continuation): Beginning 4 weeks after the completion of induction therapy, patients who have stable disease or better at time of post-induction restaging receive rituximab IV on day 1. Treatment repeats every 8 weeks for 2 years in the absence of disease progression or unacceptable toxicity.

Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.~Arm E (continuation): Beginning 4 weeks after the completion of induction therapy, patients who have stable disease or better at time of post-induction restaging receive rituximab as in arm D.
- Arm C then Arm F (Induction with Bendamustine+Rituximab; Continuation with Lenalidomide + Rituximab) (Type: EXPERIMENTAL): Arm C (induction): Patients receive rituximab IV on day 1 and bendamustine hydrochloride IV over 1 hour on days 1 and 2. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.~Arm F (continuation): Immediately after completing induction therapy, patients who have stable disease or better at time of post-induction restaging receive oral lenalidomide on days 1-21. Treatment repeats every 4 weeks for 13 courses in the absence of disease progression or unacceptable toxicity. Beginning 4 weeks after the completion of induction therapy, these patients receive rituximab IV on day 1. Treatment repeats every 8 weeks for 2 years in the absence of disease progression or unacceptable toxicity.
