Having now covered a number of medical conferences related to cancer, I continually find myself looking up the same acronyms and abbreviations again and again to remind myself what they mean. There are a lot of them in cancer research. Certain abbreviations are common enough that I immediately recognize them, such as OS (overall survival), PFS (progression-free survival) and NED (no evidence of disease). Others I recognize because of their use in other studies (e.g., IRB for Institutional Review Board), because they’re common procedures (e.g., ECG for electrocardiogram), or because they are the name of a cancer (CRC for colorectal cancer) or another condition (UTI for urinary tract infection).
But so many abbreviations, even ones I may have seen a dozen times, catch me off guard because it’s been a while since I covered cancer. To that end, I’ve gone through a bunch of online glossaries of cancer acronyms and pulled the ones I found to occur most frequently.
To give you a sense of the abbreviations that appear on it, I’ve provided three shorter lists of abbreviations below, one for cancer types, one for terms specific to cancer and one of common terms used in studies more broadly, whether in oncology or other fields. I’ve also included my sources at the bottom for those who want the comprehensive glossaries.
