Delayed surgery for more than 9 weeks induces worse survival outcomes in locally advanced rectal cancer patients with poor response to neoadjuvant chemoradiotherapy: a propensity score matched cohort study.

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
Background: The association between delayed surgery and survival outcomes in locally advanced rectal cancer patients with a poor response to neoadjuvant chemoradiotherapy (nCRT) remains unclear. This study aimed to determine the optimal timing of surgery following nCRT in these patients and to explore the association between delayed surgery and survival outcomes. Methods: Restricted cubic spline curves were used to determine the optimal timing of surgery for patients with a poor response to nCRT (ypT2-4N0 or ypTxN+). The patients were divided into two groups: the early surgery group and the delayed surgery group. Propensity score matching (PSM) analysis was employed to reduce the selection bias and survival analysis was conducted to assess the survival differences. Immunostaining of post-operative specimens was performed to investigate whether the difference in survival was associated with the CD8 Results: A total of 583 patients were enrolled in this study. The optimal timing for surgery was determined to be 9 weeks after nCRT. In PSM analysis, delayed surgery was associated with worse disease-free survival (63.0% vs 76.3% at 5 years, 53.0% vs 76.3% at 10 years; Conclusions: Patients who had a poor tumor response after nCRT, detected by using magnetic resonance imaging restaging or other assessments, need timely radical surgery without delay.
