Antineoplastons (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Human / Clinical Studies

continued...

In the patient with metastatic breast cancer, A10 was added to a variety of chemotherapeutics. Rapid tumor growth was followed by the addition of antineoplaston AS2-1 and additional chemotherapy to the treatment regimen. Two weeks following this treatment, a chest x-ray showed marked reduction in size and number of metastatic tumors, and tumor sizes decreased further over the next 5 months.[4]

The patient with anaplastic astrocytoma received antineoplaston AS2-1 in addition to other chemotherapy and radiation. An MRI 6 weeks after diagnosis showed a 50% reduction in tumor diameters.[4]

The third patient with metastatic lung cancer received antineoplaston A10 in addition to chemotherapy followed by radiation. Although initially diagnosed as inoperable, after 1 month of this treatment the patient was reconsidered and underwent a middle and lower lobectomy. Follow-up showed the patient in good condition, and a CT scan had confirmed no trace of tumor postoperatively.[4]

The addition of other therapies to the administration of antineoplastons is a confounding factor in assessing the results of antineoplaston treatment.

Antineoplaston AS2-5

In a 1986 study, antineoplaston AS2-5 injections were administered to 13 patients with 15 various malignancies (two patients each had two different malignancies).[5] All patients had stage IV disease and ranged in age from 20 to 64 years. Only patients who had an expected survival longer than 1 month were eligible for the study.

In addition to antineoplaston AS2-5 injections, two patients also received injections of antineoplaston AS2-1, and one patient received antineoplaston A10 after surgical intervention for a recurrence. Patients received other drugs such as antibiotics, analgesics, anti-inflammatory agents, anti-emetics, bronchial dilators, diuretics, corticosteroids, antihistamines, and uricosuric agents.

Side effects included chills and fever in two patients; swelling of the joints, bone pain, and redness of hands and feet in one patient; increase in platelet count in one patient; and an increase in plasma globulin in one patient.

Two patients were classified as having achieved complete remission, four patients were classified as having stable disease, six had disease progression, and one patient had a mixed response. During the study, eight patients discontinued treatment and were lost to follow-up, and three patients died. At the time of study publication, one patient who was given A10 after surgical intervention for recurrence was reported to be free of cancer for a period of slightly more than 4 years.[5]

Antineoplaston A2

In a 1987 study, 15 patients received antineoplaston A2 through intravenous subclavian catheter. Minor side effects were noted in four patients: fever, chills, and muscle pain. Of the 15 patients, 9 had objective response to treatment: complete tumor response in 7 and partial tumor response in 2. Five patients had stable disease, and one had disease progression. Follow-up showed three patients with complete response were cancer-free 5 years after treatment, and three patients were known to have survived for 4 years from the beginning of the study. Three patients were followed for 2 years, at which time they discontinued AS2-1 therapy. Five patients died within 2 years of the start of the study, and one patient was lost to follow-up.[6]
