Partial remissions were reported in two cases, one each of stage III lung adenocarcinoma and chronic myelogenous leukemia in blastic phase. The patient with lung cancer had received prior radiation therapy; both patients developed disease progression and had died by the time of study publication. Seven cases were reported as having stable disease, and six patients had disease progression. Ten patients discontinued antineoplaston therapy during the study: two who were in complete remission, one in partial remission, and seven with stable disease.
Antineoplastons A10 and AS2-1
A 1998 case series from Japan discussed three patients enrolled in a phase I study of antineoplastons A10 and AS2-1. Diagnoses included one case of breast cancer metastatic to the lung, one case of an anaplastic astrocytoma/thalamic glioma, and one case of large cell lung carcinoma (stage IIIB). All patients also received chemotherapy and radiation therapy.
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.
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.
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.
The addition of other therapies to the administration of antineoplastons is a confounding factor in assessing the results of antineoplaston treatment.
In a 1986 study, antineoplaston AS2-5 injections were administered to 13 patients with 15 various malignancies (two patients each had two different malignancies). 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.
