Accessing a specific abstract is quite a bit clumsy this year!
After you click on the link of the above post (#427) a very large pdf file is downloaded (take quite a bit of time depending on your internet connection speed) to your computer.
Double click on the downloaded pdf file which contain all the abstracts to open it.
Click on the below link for schedule.
https://www.sabcs.org/Program/Schedule-at-a-Glance
On the left panel of the displayed page, click on a specific day or session
A list of abstracts or presentation titles will be displayed such as “pd2-01” (from Poster Session 2), or “Statistical considerations for precision medicine” (from Tuesday schedule).
Cut and paste “pd2-01” or “Statistical considerations for precision medicine” into the search field of the pdf viewer that is showing the big file with all the abstracts. Press “return” which causes the pdf viewer to search for all locations with matching phrase. Now you should be able to read your topic of interest. Note that it will take a minute or two for the search result to become available since it's a very large file.
