Current therapies for advanced Head and Neck 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 advanced Head and Neck Cancer.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with advanced Head and Neck Cancer.

Advanced Head and Neck Cancer 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 advanced Head and Neck 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 advanced Head and Neck 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.

DISEASE CHARACTERISTICS:

• Histologically confirmed cancer of the head and neck that is unlikely to respond to existing therapy and for which no curative therapy exists

  • Metastatic disease OR incurable with surgery or radiation

• Measurable disease by CT scan or MRI

  • Tumor must be at least 2 cm for the lymph nodes located in the head, neck, axillary, inguinal or femoral areas and at least 0.5 cm for other areas
