This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the treatment of childhood and adult Langerhans cell histiocytosis. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.
Antineoplastons are chemical compounds that are found normally in urine and blood. For use in medical research, antineoplastons can be made from chemicals in a laboratory. (See Question 1.)
Antineoplaston therapy was developed by Dr. S. R. Burzynski, who proposed the use of antineoplastons as a possible cancer treatment in 1976. (See Question 2.)
No randomized, controlled trials showing the effectiveness of antineoplastons have been published in peer-reviewed scientific journals. (See Question...
This summary is reviewed regularly and updated as necessary by the PDQ Pediatric Treatment Editorial Board, which is editorially independent of the National Cancer Institute (NCI). The summary reflects an independent review of the literature and does not represent a policy statement of NCI or the National Institutes of Health (NIH).
Board members review recently published articles each month to determine whether an article should:
be discussed at a meeting,
be cited with text, or
replace or update an existing article that is already cited.
Changes to the summaries are made through a consensus process in which Board members evaluate the strength of the evidence in the published articles and determine how the article should be included in the summary.
The lead reviewers for Langerhans Cell Histiocytosis Treatment are:
Robert J. Arceci, MD, PhD (Phoenix Children's Hospital)
Louis S. Constine, MD (James P. Wilmot Cancer Center at University of Rochester Medical Center)
Thomas G. Gross, MD, PhD (National Cancer Institute)
Kenneth L. McClain, MD, PhD (Texas Children's Cancer Center and Hematology Service at Texas Children's Hospital)

Levels of Evidence
Some of the reference citations in this summary are accompanied by a level-of-evidence designation. These designations are intended to help readers assess the strength of the evidence supporting the use of specific interventions or approaches. The PDQ Pediatric Treatment Editorial Board uses a formal evidence ranking system in developing its level-of-evidence designations.
