Preoperative chemoradiotherapy with the TEGAFIRI regimen achieves significant local control in locally advanced rectal cancer.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aims to evaluate both the short- and long-term outcomes of preoperative chemoradiotherapy (CRT) using the tegafur-uracil/calcium folinate/irinotecan (TEGAFIRI) regimen in patients with locally advanced rectal cancer (LARC). While total neoadjuvant therapy (TNT) is becoming more common, CRT may still be the optimal approach in certain cases to improve prognosis and reduce adverse events.
methodsThis single-center, retrospective cohort study included patients with histologically confirmed nonmetastatic primary adenocarcinoma of the lower rectum treated with preoperative CRT using the TEGAFIRI regimen (TEGAFIRI group). The control group comprised patients treated with tegafur-uracil/calcium folinate (UFT group). The primary endpoint was the pathologic complete response (pCR) rate. Secondary endpoints included adverse events, overall survival (OS), disease-free survival (DFS), distant recurrence-free survival (DRFS), and local recurrence-free survival (LRFS). The background was adjusted using inverse probability weighting (IPW) calculated with the propensity score.
resultsThe TEGAFIRI group consisted of 79 patients, while the UFT group included 264. The standardized pCR rates through the IPW were as follows: TEGAFIRI group: 24.3%, UFT group: 8.8%, and the difference in pCR was 15.4% (P = 0.01). Adverse events of grade 3 or higher were observed in 15.2% vs. 8.7% (adjusted) (13.6% vs. 9.1% crude) in the TEGAFIRI group and the UFT group. The standardized LRFS was significantly higher in the TEGAFIRI group (HR = 0.39, (95% CI 0.16-0.98), P = 0.045). There were no significant differences in OS, DFS, or DRFS between groups.
conclusionsThe TEGAFIRI regimen for preoperative CRT in LARC demonstrated a high pCR rate and reduced local recurrence, with manageable adverse events.
