All study participants must be registered into the mandatory RevAssist® program, and be willing and able to comply with the requirements of RevAssist®.~10. Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 -14 days prior to and again within 24 hours of prescribing lenalidomide and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 4 weeks before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing.~11.

For patients with bulky disease (tumors \>5cm) must be able to take aspirin (81 mg or 325 mg) daily as prophylactic anticoagulation (patients intolerant to ASA may use warfarin or low molecular weight heparin.~Exclusion Criteria:~1. Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.~2. Pregnant or breast feeding females.~3. Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.~4. Use of any chemotherapy or experimental therapy within 28 days of enrollment.~5. Known hypersensitivity to thalidomide.~6. The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.~7. Any prior use of lenalidomide.~8. Concurrent use of other anti-cancer agents or experimental treatments.~9. Known positive for HIV or infectious hepatitis type B or C. (Hepatitis B core antibody can be positive if Hep B surface antigen is negative and no HBV DNA in blood, indicating a cleared infection.)

Study Arms:
- Schedule A (lenalidomide, rituximab) (Type: EXPERIMENTAL): Participants receive lenalidomide PO on days 1-21 and rituximab IV over 4-8 hours on day 1 of courses 1-12. Courses repeat every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity
- Schedule B (lenalidomide, rituximab) (Type: EXPERIMENTAL): Participants receive lenalidomide PO on days 2-22 and rituximab IV over 4-8 hours on days 1, 8, 15, and 22 of course 1 and on day 1 of all subsequent courses. Courses repeat every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
