Combination Therapy With 5-Fluorouracil, Interferon-an Interleukin-2, & Thalidomide for Metastatic, Advanced or Recurrent Renal Cell Carcinoma

Inclusion Criteria: All patients must have histologically proven renal cell carcinoma which is metastatic, non-resectable and/or recurrent. Patients must have bidimensionally measurable disease as defined in Section 10.1a documented within 28 days prior to registration. X-rays, scans, or physical exam of all non-measurable disease must be completed within 42 days prior to registration. Prestudy chest x-ray must be done within 42 days prior to registration. Prior treatment with drugs included in this protocol is permitted if such prior treatment occurred more than 6 months previous or if patient is currently exhibiting minor, mixed or partial response to any of these drugs. Prior treatment with other drugs is allowed as long as therapy was discontinued at least one month previously. Prior radiation therapy (to less than 25% of the bone marrow only, see section 19.2), or surgery are allowed. At least 4 weeks must have elapsed since the completion of radiation therapy, and there must be measurable disease outside the radiation fields. At least 3 weeks must have elapsed since completion of surgery. Patients must have had an EKG performed within 28 days prior to registration. Patients must have a Southwest Oncology Group performance status of 0-2 as defined in Section 10.4. Exclusion Criteria: Patients must not be receiving or planning to receive concomitant biologic therapy, radiation therapy, hormonal therapy, or other chemotherapy while on this protocol (including G/GM-CSF). Patients with currently untreated brain metastases or brain metastases on current therapy are not eligible. Patients with prior brain metastases S/P radiation and/or surgery, and with stable response, confirmed by MRI, off corticosteroids may be eligible. Brain MRI within 28 days of treatment and consultation with the Study Coordinator is required for such patients. Pregnant or nursing women may not participate. Women/men of reproductive potential may not participate unless they have agreed to use an effective contraceptive method. Patients with other serious illnesses, serious active infections requiring treatment with antibiotics, those requiring ongoing therapy with other investigational drugs or those receiving or expected to require corticosteroids are not permitted. Patients with known AIDS or HIV-1 associated complex or known to be HIV antibody seropositive are not eligible. In calculating days of tests and measurements, the day a test or measurement is done is considered Day 0. Therefore, if a test is done on a Monday, the Monday four weeks later would be considered Day 28. This allows for efficient patient scheduling without exceeding the guidelines. If Day 28 or 42 falls on a weekend or holiday, the limit may be extended to the next working day. Patients must be informed of the investigational nature of this study and give written in-formed consent in accordance with institutional and federal guidelines. Patients must be registered with the UNM Cancer Center Protocol Office. All records and flow sheets must be sent to this office. Active substance abuse can lead to unexpected and dangerous drug interactions and toxicities and impair compliance; therefore, this condition is an exclusion to registration or continuation on this study. Patients with a history of substance abuse must have blood or urine testing prior to registration on protocol. Psychosocial screening by the clinic psychologist or social worker is also suggested but not required. Patients found to be actively engaged in substance abuse while on protocol may be discontinued from protocol treatment at the direction of their physician and/or the study coordinator.
