High-frequency KRAS mutations in pancreatic adenocarcinoma: prognostic significance and potential co-targeting therapies.

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: Kirsten rat sarcoma viral oncogene homolog (KRAS) is among the most frequently mutated oncogenes across multiple cancers. Developing prognostic indicators based on KRAS mutations and advancing targeted KRAS inhibitors remain critical challenges in oncology. Notably, different KRAS mutations are associated with distinct biological behaviors, each carrying unique prognostic and therapeutic implications. The study aims to investigate and explore the characteristics of KRAS mutations and their impact on cancer patient prognosis. Methods: We performed a comprehensive pan-cancer analysis using publicly available The Cancer Genome Atlas (TCGA) Program data to investigate the prognostic significance of KRAS mutations in pancreatic adenocarcinoma (PAAD), colorectal cancer (CRC), and lung adenocarcinoma (LUAD). Kaplan-Meier survival analysis and univariate and multivariate Cox regression models were applied to assess the impact of KRAS mutations on patient outcomes. Additionally, KRAS mutations were detected using Sanger sequencing in genomic DNA extracted from paraffin-embedded tissues of patients enrolled from 2022 to 2024. Mutation rates and their associations with genetic background factors were analyzed. Results: The pan-cancer analysis revealed high KRAS mutation frequencies in PAAD (77.4%), COADREAD (41.1%), and LUAD (27.2%), with the most prevalent mutations being G12C, G12D, and G12V. Sanger sequencing further confirmed the high mutation frequencies of KRAS Conclusions: KRAS mutations serve as independent prognostic risk factors in PAAD, and targeting these mutations may offer a promising therapeutic approach to improve patient outcomes.
