What this page is
A Society education page about the 2023 meeting’s radiation-immune conversation: in-situ vaccination, combination with checkpoint blockade, dose and fractionation as immunological variables, and the stubborn rarity of reproducible abscopal responses. It is not a claims page. It is not a Clay Hess bibliography dressed as a meeting.
How to cite a 2023 meeting abstract
Use this pattern, and stop there:
Author(s). Title. Presented at: American Society for Radiation Oncology Annual Meeting; October 1–4, 2023; San Diego, CA. Abstract [number]. Published in: Int J Radiat Oncol Biol Phys. 2023;117(2 suppl).
Do not append a fabricated doi:10…. The supplement is the citation.
Abstract numbers, if used, must come from the published program or supplement — not
from memory.
What SIRiiM takes from that meeting
- Radiation dose, volume and timing are immunological variables, not only oncologic ones.
- Combination with immunotherapy is a protocol problem (sequence, selection, endpoints), not a slogan.
- Out-of-field response remains uncommon enough that every positive case still has to explain the negative ones. See abscopal.
- Low-dose immunomodulation for non-malignant disease is a different conversation from high-dose in-situ vaccination. See immunity and arthritis.
Related work that does have a DOI
Immunomodulatory whole-lung LDRT for COVID-19 pneumonia was published as a full Red Journal paper in 2021, with a real DOI. That paper is not an ASTRO 2023 abstract. Do not collapse the two.1
The randomised, double-blind COVID LDRT trial that did not improve outcomes is likewise a 2021 full paper, not a 2023 abstract.2
Where to go next
The Society’s ongoing record is the journal, not a single meeting: theorangejournal.org. Primary-care teaching of the same material starts at /pcp.
Meeting education, not a substitute for the published supplement. Verify abstract numbers against the Red Journal ASTRO 2023 supplement before citing them in print.
