antineoplaston therapy in treating patients with stage iv kidney cancer

Conditions: Stage IV Kidney Cancer

Summary: current therapies for stage iv kidney cancer provide very limited benefit to the patient. the anti-cancer properties of antineoplaston therapy suggest that it may prove beneficial in the treatment of stage iv kidney cancer. purpose: this study is being performed to determine the effects (good and bad) that antineoplaston therapy has on patients with stage iv kidney cancer.

overview: this is a single arm, open-label study in which patients with stage iv kidney cancer receive gradually escalating doses of intravenous antineoplaston therapy (atengenal + astugenal) until the maximum tolerated dose is reached. treatment continues up to12 months in the absence of disease progression or unacceptable toxicity. objective s: * to determine the efficacy of antineoplaston therapy in patients with stage iv kidney cancer, as measured by an objective response to therapy (complete response, partial response or stable disease). * to determine the safety and tolerance of antineoplaston therapy in patients with stage iv kidney cancer. * to determine objective response, tumor size is measured utilizing mri scans, which are performed every 8 weeks for the first two years, every 3 months for the third and fourth years, every 6 months for the 5th and sixth years, and annually thereafter.

Eligibility criteria:
disease characteristics: * histologically confirmed stage iv adenocarcinoma or transitional cell carcinoma of the kidney that is unlikely to respond to existing therapy * measurable disease by mri or ct scan * tumor must be more than 2 cm for lymph nodes in head, neck, axillary, inguinal, or femoral areas and at least 0.5 cm for other locations patient characteristics: age: * 18 and over performance status: * karnofsky 60-100% life expectancy: * at least 2 months hematopoietic: * wbc at least 2,000/mm\^3 * platelet count at least 50,000/mm\^3 hepatic: * no hepatic insufficiency * bilirubin no greater than 2.5 mg/dl * sgot and sgpt no greater than 5 times upper limit of normal renal: * no renal insufficiency * creatinine no greater than 2.5 mg/ml * no history of renal conditions that contraindicate high dosages of sodium cardiovascular: * no known chronic heart failure * no uncontrolled hypertension * no history of congestive heart failure * no history of other cardiovascular conditions that contraindicate high dosages of sodium pulmonary: * no severe lung disease, such as chronic obstructive pulmonary disease other: * not pregnant or nursing * fertile patients must use effective contraception during and for 4 weeks after study participation * not a high medical or psychiatric risk * no concurrent nonmalignant systemic disease that would preclude therapy * no active infection prior concurrent therapy: biologic therapy: * at least 4 weeks since prior immunotherapy * no concurrent immunomodulatory agents chemotherapy: * at least 4 weeks since prior chemotherapy (6 weeks for nitrosoureas) and recovered * no concurrent antineoplastic agents endocrine therapy: * concurrent corticosteroids allowed radiotherapy: * at least 8 weeks since prior radiotherapy and recovered surgery: * recovered from prior surgery other: * prior cytodifferentiating agents allowed * no prior antineoplastons
