Sure. I'm starting to work on a compilation. If you send me an email I can point you at it. I don't have them on me at the moment.
One time it was a 10 year old research paper detailing the simple fact that if you don't force a particular chemo drug into a person over the standard 30 minutes but instead do it over 2 hours you have a much reduced chance of permanent side-effects such as neuropathy. The doctors changed the treatment in response to the paper, and FWIW the person did not develop have any permanent side effects.
The fact that that paper exists and is 10 years old and had no change on the treatements of many people since then (many of which could have potentially avoided permanent damage) led me to further question the "scientific" nature of modern medicine.
Another rich vein of research is in the numerous research on the effects of certain medicinal mushrooms as an adjunct to cancer treatments, both radiation and chemo. In allmost all cases, the effects were very positive and replicable. Some of these papers are also over 10 years old.
I know big pharma cannot be trusted as they're in it to have customers for life, but I've never considered using research papers to change treatments.
