Locoregional and systemic control after total neoadjuvant therapy with short-course radiotherapy for locally advanced rectal cancer: long-term outcomes from the LARCT-US study.
Observational study in The British journal of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTotal neoadjuvant treatment (TNT) results in more complete responses and less risk of distant metastasis (DM) compared with chemoradiotherapy in locally advanced rectal cancer (LARC). The best schedule and the most suitable patients are unknown. In Sweden, after the closure of the RAPIDO trial, all hospitals in five out of six healthcare regions treated LARC patients with an abbreviated RAPIDO schedule, LARCT-US. Long-term data are reported.
methodsBetween July 2016 and June 2020, LARC patients with at least one high-risk criterion for recurrence according to staging MRI (cT4, cN2, mesorectal fascia involvement <1 mm, extramural vascular involvement, lateral node involvement) received TNT consisting of 5 × 5 Gy followed by four cycles of CAPOX/six cycles of FOLFOX.
resultsCuratively treated patients (437 of 462) were analysed after a median of 6.5 (interquartile range 5.9-7.2) years of follow-up. cT4 was seen in 53.5%. Sixty-two patients with a cCR entered a watch-and-wait programme (21 patients with regrowth) and 375 patients underwent primary surgery. At 5 years, of the 437 patients, locoregional recurrence (LRR) occurred in 26 patients (5.9% (95% c.i. 3.7% to 8.2%)) and DM occurred in 108 patients (24.7% (95% c.i. 20.7% to 28.7%)). The distal resection margin was ≤10 mm in 8.3% of patients after a sphincter-saving procedure (a lower percentage than in RAPIDO). The 109 patients (24.9%) with a complete response (48 patients with a cCR sustained for >1 year after the start of radiotherapy and 61 patients with a pCR) had excellent outcomes (0% with LRR and 3.7% with DM).
conclusionTNT consisting of 5 × 5 Gy followed by four cycles of CAPOX/six cycles of FOLFOX resulted in excellent locoregional and distant control, despite inclusion of more advanced tumours than previous TNT studies. The low LRR risk in LARCT-US could be explained by more adequate distal resection margins practiced at Swedish centres.
