Evolution of Prognosis and Management in Curative Treatment of Locally Recurrent Rectal Cancer: A Comprehensive Analysis from 2000 to 2023.
Article in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDespite advances in diagnosis and treatment, locally recurrent rectal cancer (LRRC) remains a complex condition associated with a poor prognosis. This study aimed to evaluate long-term trends in the management of and oncological outcomes for patients with LRRC treated in a Dutch tertiary referral center.
methodsAll consecutive patients with a confirmed diagnosis of a first LRRC undergoing curative-intent surgical resection at our referral center between 2000 and 2023 were retrospectively analyzed. Primary outcomes were trends in overall survival (OS), disease-free survival (DFS), clear (R0) resection rate, and postoperative complication rates. Cumulative sum (CUSUM) analysis was used to visualize changes in these outcomes over time. Secondary endpoints included temporal changes in prognostic factors associated with improved OS and DFS.
resultsA total of 560 patients undergoing curative-intent surgical resection were included. Over time, patients presented with more comorbidities (p < 0.001), more multifocal disease (p < 0.001), and synchronous metastasis (p < 0.001). The R0 resection rate improved from 59% to 78% over the study period (p < 0.001). CUSUM analyses demonstrated an upward trend in OS and DFS, indicating a cumulative improvement in survival relative to the reference survival probability. In univariable Cox regression, the most recent time period (2018-2023) was significantly associated with improved OS (hazard ratio 0.75; 95% confidence interval 0.58-0.97; p = 0.030).
conclusionsOver the past two decades, the outcomes of patients undergoing curative-intent treatment for LRRC have steadily improved. This may reflect advances in diagnostics, neoadjuvant therapy, surgical technique and perioperative care, centralization of care, and patient selection.
