Rectal neoadjuvant EBRT pre-operative short-course (eviQ ID 1874)

Endorsed eviQ protocol for pre-operative short-course radiotherapy (25 Gy in 5 fractions) for rectal cancer. It notes that few published protocols give organ limits for short-course IMRT or VMAT, and takes its bowel and bladder values from the Royal College of Radiologists' national rectal IMRT guidance. It also asks for care in sparing the anal canal for tumors 6 cm or more from the anal verge. Its review was due 30 June 2026, so a newer version may appear.

One of the few protocols with organ limits written for 5 × 5 Gy rectal IMRT/VMAT — bowel loops, bowel cavity and bladder, taken from the UK rectal IMRT guidance.
