6. ECOG performance status of 2 at study entry (see Appendix I).

7. Laboratory test results within these ranges:

   • Absolute neutrophil count 500/mm3
   • Platelet count 50,000 /mm3
   • Serum creatinine 2.0 mg/dL
   • Total bilirubin 1.5 mg/dL
   • AST (SGOT) and ALT (SGPT) 2 x ULN or 5 x ULN if hepatic metastases are present.
8. 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 starting 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 28 days before she starts taking lenalidomide.

All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. See Appendix V: Risks of Fetal Exposure, Pregnancy Testing Guidelines and Acceptable Birth Control Methods, AND also Appendix VI: Education and Counseling Guidance Document.

9. Disease free of prior malignancies for 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "insitu" of the cervix or breast

   • A female of childbearing potential is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).

Exclusion Criteria:

4. Use of any other experimental drug or therapy within 28 days of baseline.
5. Known hypersensitivity to thalidomide.
