1 · What the graph read from it

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.

2 · The registry

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

backgroundKRAS mutations are detected in ~40% of colorectal cancer (CRC), yet their prognostic value is heterogeneous across specific substitutions; the impact of uncommon variants, particularly in non-metastatic disease, remains uncertain.

methodsWe evaluated the prognostic role of the relatively infrequent KRAS G12A substitution in two independent retrospective cohorts of stage II-III CRC treated with surgical resection without neoadjuvant therapy: an institutional series (FMU; n = 299) and a public dataset (AC-ICAM; n = 178). Tumors were genotyped for KRAS (and BRAF in AC-ICAM), and relapse-free survival (RFS) and overall survival (OS) were investigated.

resultsKRAS G12A comprised 3.0% (FMU) and 3.4% (AC-ICAM). Across genotypes, G12A showed the highest univariable hazards compared to wild-type (WT) references for both RFS and OS in each cohort. Notably, RFS events among G12A clustered within 12 months of surgery. In multivariable Cox models, G12A remained independently associated with worse RFS and OS in each cohort, whereas non-G12A KRAS mutations did not differ significantly from the WT references.

conclusionsAcross two cohorts, KRAS G12A identified a small but clinically meaningful high-risk subset of stage II-III CRC characterized by early recurrence and inferior survival. Recognition of this variant may inform postoperative risk stratification in the adjuvant setting.
