Current therapies for Stage IV non-small cell lung 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 lung cancer

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Stage IV lung cancer.

Stage IV non-small cell lung cancers receive Antineoplaston A10 and AS2-1 capsules orally six to seven times a day. Treatment continues in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:

• To determine the efficacy of Antineoplaston therapy in patients with Stage IV non-small cell lung 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 non-small cell lung cancer.
• To determine objective response, tumor size is measured utilizing MRI scans, which are performed every 4 months for 2 years, every 6 months for 2 years, and then annually for 2 years thereafter.

DISEASE CHARACTERISTICS:

• Histologically confirmed stage IV non-small cell lung cancer that cannot be cured with existing therapeutic regimens

• 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
