antineoplaston therapy in treating patients with high-grade stage ii - stage iv non-hodgkin's lymphoma

Conditions: Non-hodgkins Lymphoma

Summary: current therapies for refractory or recurrent high-grade stage ii - iv non-hodgkin's lymphoma provide very limited benefit to the patient. the anti-cancer properties of antineoplaston therapy suggest that it may prove beneficial in the treatment of refractory or recurrent high-grade stage ii - iv non-hodgkin's lymphoma. purpose: this study is being performed to determine the effects (good and bad) that antineoplaston therapy has on patients with refractory or recurrent high-grade stage ii - iv non-hodgkin's lymphoma.

refractory or recurrent high-grade stage ii - iv non-hodgkin's lymphoma patients 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. objectives: * to determine the efficacy of antineoplaston therapy in patients with refractory or recurrent high-grade stage ii - iv non-hodgkin's lymphoma, 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 refractory or recurrent high-grade stage ii - iv non-hodgkin's lymphoma. * to determine objective response, tumor size is measured utilizing physical examination, radiologic studies, and bone marrow biopsies as necessary, 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 proven stage ii, iii, or iv high-grade non-hodgkin's lymphoma that has not responded to, or has relapsed after a standard primary chemotherapy regimen plus at least 1 standard second-line salvage chemotherapy regimen note: a new classification scheme for adult non-hodgkin's lymphoma has been adoptedby pdq. the terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. however, this protocol uses the former terminology. patient characteristics: age: * 18 and over performance status: * karnofsky 60-100% life expectancy: * at least 2 months hematopoietic: * wbc greater than 2000/mm\^3 * platelet count greater than 50,000/mm\^3 hepatic: * bilirubin no greater than 2.5 mg/dl renal: * creatinine no greater than 2.5 mg/dl * no history of renal conditions that contraindicate high dosages of sodium cardiovascular: * no uncontrolled hypertension * no history of congestive heart failure * no history of cardiovascular conditions that contraindicate high dosages of sodium other: * not pregnant or nursing * fertile patients must use effective contraception during and for 4 weeks after study participation * no active infection requiring treatment prior concurrent therapy: biologic therapy: * at least 4 weeks since prior immunotherapy and recovered * no concurrent immunomodulatory agent (e.g., interferon or interleukin-2) chemotherapy: * see disease characteristics * at least 4 weeks since prior chemotherapy (6 weeks for nitrosoureas) and recovered * no concurrent antineoplastic agent endocrine therapy: * at least 4 weeks since prior dexamethasone, prednisone, or other corticosteroids * no concurrent corticosteroid radiotherapy: * at least 8 weeks since prior radiotherapy and recovered surgery: * not specified other: * no prior antineoplaston therapy * no concurrent antibiotics, antifungals, or antivirals
