Nina Niu Sanford, Assistant Professor and Chief of Gastrointestinal Radiation Oncology at Harvard/Brigham and Women’s Hospital/Massachusetts General Hospital, shared a post on X:
“New YouTube video by request Rad Onc 101!
10 min overview of rad onc: dosing, terminology, etc.
Non rad oncs:
Promise your rad onc colleagues will be super impressed if you throw around these terms at next tumor board.
Slides below again (just 4) with.
Link in next post.”
“Link here.
Tried side by side this time with me/slides.”
- “We use the term BED, which refers to *true* biologic dose delivered to tissues – depending on total dose and dose/fraction.
Don’t need to know details of formula but understand that:
- Bigger fraction sizes more potent.
- Different regimens can achieve same BED.”
“2. I call these radiation “categories”.
Super important to understand IMO. Saw in recent HCC guidelines comparing protons versus SBRT which doesn’t make sense…one is a particle type (proton) another refers to fraction size/technique (SBRT).
Lol plus the ram, will explain.”
“3. How we define our targets – what does GTV/PTV etc mean?”
“4. Lastly, more radiation terminology…sorry our field has confusing terminology!
Explained in video.”
