Antineoplastons (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Summary of the Evidence for Antineoplastons
To assist readers in evaluating the results of human studies of complementary and alternative medicine (CAM) treatments for cancer, the strength of the evidence (i.e., the "levels of evidence") associated with each type of treatment is provided whenever possible. To qualify for a level of evidence analysis, a study must:
Be published in a peer-reviewed scientific journal.
Report on a therapeutic outcome or outcomes, such as tumor response, improvement in survival, or measured improvement in quality of life.
Describe clinical findings in sufficient detail that a meaningful evaluation can be made.
Antineoplaston therapy has been studied as a complementary and alternative therapy for cancer. Case reports, phase I toxicity studies, and some phase II clinical studies examining the effectiveness of antineoplaston therapy have been published. For the most part, these publications have been authored by the developer of the therapy, Dr. Burzynski, in conjunction with his associates at the Burzynski Clinic. Although these studies often report remissions, other investigators have not been successful in duplicating these results. (Refer to the Human/Clinical Studies section of this summary for more information.) The evidence for use of antineoplaston therapy as a treatment for cancer is inconclusive. Controlled clinical trials are necessary to assess the value of this therapy.

Separate levels of evidence scores are assigned to qualifying human studies on the basis of statistical strength of the study design and scientific strength of the treatment outcomes (i.e., endpoints) measured. The resulting two scores are then combined to produce an overall score.
