Five-year overall survival of early- and late-onset colorectal cancer in Medellín, Colombia: a comparative study.
Article in Journal of cancer research and clinical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeEarly-onset colorectal cancer (CRC) (EOCRC, < 50 years) has distinct clinicopathological features from late-onset CRC (LOCRC, ≥ 50 years). However, evidence on survival outcomes is contradictory. We aimed to analyse the differences in 5-year overall survival (OS) between EOCRC and LOCRC.
methodsA retrospective cohort study was conducted during 2018-2022. Individuals aged ≥ 18 years diagnosed with CRC at two hospitals in Medellín, Colombia were included. Clinicopathological and survival data were retrieved from the medical records and a public government database. Patients were categorized into EOCRC and LOCRC groups. Five-year OS rates were calculated using the Kaplan-Meier method and prognostic factors for OS were identified through Cox regression models.
resultsAmong 1022 patients, 52.5% were female, and 13.5% (n = 138) had EOCRC. Patients with EOCRC showed higher 5-year OS rates than LOCRC patients (54% vs. 32%). Univariable analyses indicated a 37% lower risk of death for EOCRC compared to LOCRC (HR: 0.633, 95%CI: 0.476-0.840, p = 0.002). After multivariable analyses, advanced staging and higher tumour grading were prognostic factors for worse OS (HR: 2.127, 95% CI:1.405-3.220, p = 0.0001; and HR: 12.896, 95%CI: 6.310-26.355, p = 0.000; respectively), and being in the EOCRC group remained as a prognostic factor for higher OS (HR: 0.482, 95% CI: 0.336-0.690, p = 0.000).
conclusionEOCRC is associated with significantly better 5-year OS rates and prognosis compared to LOCRC. Advanced stage and higher tumour grading are predictors of lower OS among all CRC patients. These findings highlight the importance of age-related risk stratification and personalized therapeutic approaches in CRC.
