The Shifting and Evolving Neoadjuvant Treatments and Surgical Platforms on Oncological Outcomes and Sphincter Preservation in Distal Rectal Cancer: A 23-Year Retrospective Experience.
Article in Journal of gastrointestinal cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 how advancements in surgical technology and evolving neoadjuvant treatment (NAT) protocols have influenced clinical, pathological, and long-term oncological outcomes in patients with locally advanced distal rectal cancer (LADRC). Particular emphasis is placed on how the evolving practice of a single high-volume colorectal surgeon has mirrored these developments over a 23-year period.
methodsThis retrospective cohort included 561 patients with LADRC who underwent NAT between 2001 and 2024. Patients were stratified into two groups based on the year 2013, which marked the institutional adoption of robotic surgery, high-resolution 3-Tesla MRI, and the formal implementation of the Watch-and-Wait (W&W) strategy: Group I (2001-2012) and Group II (2013-2024).
resultsThe median follow-up duration was significantly longer in Group 1 (191 ± 2.29 months) compared to Group 2 (71 ± 2.81 months). Local recurrence (LR) occurred in 11.6% of patients in Group 1 and 6.9% in Group 2 (p = 0.107), while distant metastasis (DM) was observed in 15.5% and 10.6%, respectively (p = 0.178) (Fig. 2). Disease-free survival (DFS) at 5 years was 67.4% (95% CI: 58.6-74.8) in Group 1 and 80.1% (95% CI: 75.6-83.8) in Group 2 (p = 0.003). At 10 years, DFS was 65.2% (95% CI: 58.6-74.8) and 79.4% (95% CI: 74.7-83.3) in Groups 1 and 2, respectively (p = 0.006). Similarly, overall survival (OS) at 5 years was 78.0% (95% CI: 67.6-82.4) in Group 1 and 91.7% (95% CI: 87.9-93.3) in Group 2 (p < 0.001). At 10 years, OS was 73.4% (95% CI: 66.0-81.1) and 90.5% (95% CI: 87.3-92.9), respectively (p < 0.001). Additionally, permanent stoma-free survival (PSFS) improved significantly over time, from 56.5% in Group 1 to 85.8% in Group 2 (p < 0.001).
conclusionThe integration of robotic surgery, high-resolution MRI, and the W&W strategy has significantly improved oncological outcomes and sphincter preservation rates in patients with LADRC over the past two decades.
