Genomic Signatures of Recurrence After Resection of Early-Stage Node-Negative Colon Cancer.
Article in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundWhereas clinicopathologic risk factors for colon cancer (CC) recurrence are well-established, the role of genomic predictors remains understudied. This study aimed to identify genomic factors associated with recurrence after resection of early-stage, node-negative CC.
methodsA retrospective cohort study was performed using clinicopathologic data, somatic mutations, and mRNA expression profiles from the cBioPortal database. The study enrolled patients with T1-3, N0, or M0 CC who underwent surgical resection and primary tumor sequencing. Those with fewer than 6 months of follow-up evaluation were excluded. Gene expression profiles were classified into consensus molecular subtypes (CMSs). Somatic mutations and CMS groups were analyzed for associations with recurrence.
resultsOf the 305 patients analyzed, 46 (15%) experienced recurrence. The median age at diagnosis was 70 years (interquartile range [IQR], 62-76 years), the gender distribution was balanced. The median follow-up period was 38 months, and the median time to recurrence was 13 months. The following 12 mutated genes were significantly associated with recurrence: KRAS (odds ratio [OR], 2.19), PIK3CA (OR, 2.13), DNAH11 (OR, 3.28), NALCN (OR, 4.69), COL6A3 (OR, 3.12), GRIN2A (OR, 4.92), COL6A1 (OR, 4.25), TNN (OR, 3.25), NEXMIF (OR, 6.97), PKHD1L1 (OR, 3.24), CDH4 (OR, 3.29), and BCL9 (OR, 4.03). Additionally, tumors classified as CMS4/mesenchymal subtype had a greater risk of recurrence (OR, 4.67) than the CMS2/canonical subtype. Patients with CMS4 or at least four mutations associated with recurrence (n = 77) had a 5-year disease-free survival rate of 57.7%.
conclusionThis study identified novel genomic signatures that may improve risk stratification in early-stage node-negative CC, potentially guiding the selection of high-risk patients for adjuvant therapy.
