Rectal neoadjuvant EBRT chemoradiation pre-operative long-course (eviQ ID 1863)
eviQ, Cancer Institute NSW
DoseLab summary
Endorsed eviQ protocol for pre-operative long-course chemoradiation of rectal adenocarcinoma. It covers simulation (supine or prone on a bellyboard, MRI and PET/CT to aid tumor delineation), IMRT/VMAT with a simultaneous integrated boost or 3D conformal treatment with a sequential boost, target volumes referenced to the international consensus guideline, and an organs-at-risk table. Its bladder and femoral head values are credited to RTOG 0822. DoseLab's rectal table reproduces selected values. Its review was due 30 June 2026, so a newer version may appear.
Why this is useful
A long-course rectal protocol with both an SIB and a sequential-boost option, and a short organ table (bladder, bowel cavity, small bowel loops, femoral heads) with the primary source for each value.
