Prognostic Factors for Patients Under 45 Undergoing Surgery for Colorectal Liver Metastases: A SEER Population-Based Study.
Article in Journal 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
BACKGROUND AND
objectivesColorectal cancer (CRC) has been on the rise in adults younger than 50. Surgical resection is a potentially curative treatment option for patients with colorectal liver metastases (CRLM). The aim of this study was to describe patient and tumor characteristics associated with disease-specific survival in young patients (< 45 years) versus older patients (≥ 45 years) with isolated CRLM.
methodsThe SEER database was queried for patients with CRLM who underwent colon and liver resection from 2010 to 2021. Patients under age 20, with metastases beyond the liver, or who had not had surgery for liver metastases were excluded. Cox regression was used to analyze demographic factors, tumor characteristics, and treatment order.
resultsThe study group consisted of 2222 patients, with 299 patients less than 45 years old, and 1923 patients at least 45 years old. Higher nodal burden was associated with worse survival in both groups. Elevated CEA was associated with worse survival only in older patients. Younger patients experienced initial longer disease-specific survival.
conclusionsTypical prognostic factors for older patients do not have the same impact on disease-specific survival for younger patients. Further study may help describe patient and tumor selection for surgical resection of colorectal liver metastases in young patients.
