A comparison of organ preservation in older adults with stage I rectal cancer.
Article in International journal of colorectal disease, 2025. 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
backgroundTotal mesorectal excision (TME) remains the primary recommended treatment for high-risk T1 and T2 rectal cancer. However, growing evidence suggests preoperative therapy may lead to eligibility for organ preservation (OP), avoiding the morbidity of major resection, which may be beneficial in older adults. The primary aim of the study was to compare rates of OP in adults 70 years of age and older to those less than 70 with T1 lesions rectal cancers with high-risk features and T2 rectal cancers.
methodsA retrospective, cohort study of patients with high-risk stage 1 rectal cancer was identified within the National Cancer Database (NCDB). Primary outcome was the association of age with receipt of organ preservation. Multivariate analysis was conducted to examine the effect of covariates on the outcome.
resultsOut of 38,714 patients, 34.4% were ≥ 70 years, 42.3% were female, and 75.6% had a Charlson Deyo comorbidity score of 0. Older adults were more likely to received OP compared to younger patients (45.6% vs 30.6%, p < 0.001). This persisted on adjusted analysis (OR 1.9, p < 0.001). Other factors predictive of receiving OP include non-Hispanic Black race/ethnicity (OR 1.5, p < 0.001), lack of insurance (OR 1.5, p < 0.001), increased comorbidity score (OR 1.7 for CDCC of 3, p < 0.001), treatment at a community facility compared to academic facility (OR 1.4, p < 0.001), and female sex (OR 1.2, p < 0.001).
conclusionsAlthough current guideline recommendations for high-risk T1 and T2 rectal cancer is TME, a significantly higher proportion of older adult patients undergo organ preservation. This is more pronounced in comorbid and disadvantaged patients.
