NOTE TO READERS: When this project lost substantial funding at the end of 2018, I lost the ability to continue publishing criteria-driven news story reviews and PR news release reviews - once the bread-and-butter of the site going back to 2006. The 3,200 archived reviews, while still educational, are getting old and difficult for me to technically maintain on the back end of the website. So I am announcing that I plan to remove these reviews from the site by April 1, 2021. The blog and the toolkit - two of the most popular features on the site - will remain. If you wish to peruse the reviews before they disappear, please do so by the end of March 2021. After that date you may still be able to access them via the Internet Archive Wayback Machine - https://archive.org/web/.

Caveats about papers presented at cancer meetings

Reuters Health reports:

Preliminary results of cancer treatment studies presented at major cancer meetings should be viewed with caution, because the final results may wind up being quite different, new research shows.

Dr. Christopher M. Booth of Queen’s University in Kingston, Ontario, and colleagues found that nearly two-thirds of abstracts presented at cancer meetings had small differences in numbers of patients, follow-up times, or results when compared with final reports of randomized clinical trials published in medical journals.

And for 10% of the presented abstracts they reviewed, researchers came to the opposite conclusion when the trial was actually published. This means study authors may have initially concluded that a treatment should be adopted, but switched to not recommending a therapy in a published report, or vice versa.

… (The author says) given the heavy media attention now given to research on cancer treatments, it’s important for both patients and doctors to be aware of when a publicized finding is the final word — and when it isn’t.
