Antineoplaston Therapy in Treating Patients With Low-Grade Non-Hodgkin's Lymphoma

Low-grade 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 to 12 months in the absence of disease progression or unacceptable
toxicity.

OBJECTIVES:

- To determine the efficacy of Antineoplaston therapy in patients with Low-grade
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
Low-grade Non-Hodgkin's Lymphoma.

- 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.

DISEASE CHARACTERISTICS:

- Histologically proven stage II, III, or IV low grade non-Hodgkin's lymphoma that is
unlikely to respond to existing therapy or for which no established therapy exists
NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by
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.
