The long and really heroic struggle that Dr. Stanislaw Burzynski has maintained with first the entrenched and self-protective power structure of the Party in Communist Poland, then with the ditto of the drug industry and its FDA mouthpiece in the US is both inspiring and dispiriting. Also highly informative. Even if your oncologist rails against Burzynski as quack/charlatan/fraud, you owe it to yourself to give a little attention to what is said in his defense by a good number of thoughtful people.
In fact we all owe it to each other to become better informed about the workings of the FDA and the drug-medical industrial complex. The recent film, Burzynski — the Movie, is a good starting place. Notice that the transcript and linked sources are available here. Burzynski’s story is also featured in Cut, Poison, Burn.
The powerful and ugly anti-Burzynski party line is easily found on Wikipedia here. All of the negative claims in the first three paragraphs there are explicitly addressed in the film, which also documents that, contrary to the Wikipedia and others’ claims, phase II trials have been done on antineoplastons, and very successfully when contrasted to other trials with other treatments. Here is a page on the movie website that explicitly speaks to the phase II trials question in great detail — link. When I visited the site on 1-24-13 I found the link to resource  had an error that prevented it from taking a visitor to the intended page. However, from the site one can make out the intended page and visit it — here. Click here for an explanation of the core results summarized in that paper by Dr. Burzynski.
