The METACER national cohort study of brain metastases in gastrointestinal cancers prospectively establishes prognostic factors.
Article in Journal of neuro-oncology, 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
purposeAvailability data are scarce and primarily retrospective in patients with brain metastasis (BM) from gastrointestinal (GI) cancers. The objective of this cohort was to determine prognostic factors for survival outcomes in patients with BM from GI cancers.
methodsMETACER is a national multicentric prospective cohort study which included patients with BM diagnosis during a histologically proven digestive cancer follow-up between 2010 and 2014. The primary endpoint was overall survival (OS). The secondary endpoints were Progression-Free survival (PFS), prognostic factors, and BM-free survival as time from disease diagnosis to BM diagnosis.
resultsMETACER included 130 patients, with colorectal cancer (CRC) (N = 105) and eso-gastric (N = 25) cancer (EGC). The median OS was 6.6 months: 7.1 months (95%CI: 4.7-9.7) in CRC patients and 5.2 months, (95%CI: 1.9-7.6) in EG patients (p = 0.827). In multivariate analysis, cerebral BM location (versus cerebellar), BM surgery, performance status (0-1 versus 2), and a unique BM were significantly associated with prolonged OS. BM-free survival were 30.8 months (95%CI:25.2-36.9) in CRC patients and 7.8 months (95%CI:3.8-13.6) in EGC patients (p < 0.001). In synchronous metastatic disease, BM-free survival were 18.6 months (95%CI:13.1-25.2) in CRC patients and 3.7 months (95%CI:0.03-7.8) in EGC patients (p < 0.001).
conclusionBM in GI cancers are of poor prognosis. BM surgery should be considered in case of unique brain lesion. In metastatic settings, EGC patients have shorter BM-free survival than CRC patients.
