Abbreviations: CT = computed tomography; 5FU = 5-fluorouracil; RT = radiation therapy.
Clinical score (CS) based on 4 adverse pretreatment findings: site <5 cm from verge, tethered or fixed to palpation, circumferential, near obstructing. CS0: 0 adverse factors; CS1: 1or 2 adverse factors; CS2: 3 or 4 adverse factors.
PROSPECT eligible: disease extent eligible for recently activated (N1048) trial (comparing preoperative RT+5FU vs FOLFOX): location at ≥5 cm, no disease ≤3 mm from mesorectal fascia, and cT <cT4.
