Intergroup randomized phase III study of adjuvant FOLFIRI, FOLFOX, or 5-FU/leucovorin for stage II/III rectal cancer: ECOG-ACRIN E3201.
Trial report in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00068692 (Intergroup Randomized Phase III Study of Postoperative Irinotecan, 5-Fluorouracil and Leucovorin vs. Oxaliplatin, 5-Fluorouracil and Leucovorin vs. 5-Fluorouracil and Leucovorin for Patients With Stage II or III Rectal Cancer Receiving Either Preoperative Radiation and 5-Fluorouracil or Postoperative Radiation and 5-Fluorouracil), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundAdjuvant 5-FU monotherapy was previously the standard treatment for stage II/III rectal cancer. This study compared adjuvant FOLFIRI, FOLFOX, and 5-FU/LV.
methodsEligible patients had T3-T4 N0 or Tany N1-3 rectal adenocarcinoma ≤12 cm from the anal verge and received pre-operative or postoperative 5-FU chemoradiotherapy (CRT). Patients were randomized to adjuvant FOLFIRI (8 cycles), FOLFOX (8 cycles), or 5-FU/LV weekly (6/8 weeks; 3 cycles). The trial planned to enroll 3,150 patients but was closed early following activation of an alternative adjuvant rectal cancer study including bevacizumab (E5204). The primary endpoint was overall survival (OS); secondary endpoints included disease-free survival (DFS), sphincter preservation, tolerability, and quality of life (QOL).
resultsThe trial enrolled 225 patients (179 randomized) before early closure. Grade 3/4 toxicity occurred in 59%, with neutropenia, leukopenia, and diarrhea being the most common. At a median follow-up of 9.7 years, no significant OS or DFS differences were observed. The rate of sphincter preservation was numerically higher with FOLFIRI and FOLFOX versus 5-FU/LV, but the difference was not statistically significant.
conclusionFOLFOX and FOLFIRI can be safely administered after CRT in rectal cancer patients safely with expected toxicities. Due to early trial closure and small sample size, the survival analysis was underpowered to detect a significant difference between regimens. CLINICALTRIALS.GOV IDENTIFIER: NCT00068692.
