Assessment of the quality of life in metastatic colorectal cancer patients with KRAS gene mutant: a case-control study.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe mutation of the KRAS (Kirsten rat sarcoma virus) gene is a prevalent genetic alteration in metastatic colorectal cancer (mCRC). According to previous research, this mutation significantly affects clinical outcomes and quality of life (QOL). This research investigated the association between KRAS mutant status and various aspects of QOL in mCRC patients.
methodsThis case-control study involved 90 admitted patients with mCRC. The patients were either mCRC with positive KRAS mutants (case group) or those without the mutation (control group). The KRAS mutation status of each patient was determined using standard molecular testing. The QOL was evaluated through validated questionnaires from the European Organization for Research and Treatment of Cancer (EORTC), including QLQ-C30 and the QLQ-CR29 questionnaire for colorectal cancer patients. Differences in QOL between the groups and the association of QOL with the odds of KRAS mutation were analyzed using appropriate statistical tests.
resultsPatients in the wild-type KRAS group had significantly higher scores on the global health status (GHS) of the QLQ-C30 scale compared to those with a KRAS mutation [(64.26 ± 4.63 vs. 49.63 ± 4, crude; p = 0.019, adjusted; p = 0.024). The mean score of the social functioning scale of the KRAS mutation group was significantly higher than the wild-type [(40 ± 5.84 vs. 24.81 ± 4.39, crude; p = 0.040, adjusted; p = 0.021)]. Based on the QLQ-CR29 questionnaire, average QOL scores were suboptimal for both groups but insignificant. Further, both crude and adjusted analyses showed that KRAS mutation odds were significantly linked to improved social functioning [(crude; OR = 1.013; P = 0.044), (adjusted; OR = 1.017; P = 0.019)] and negatively associated with GHS [(crude; OR = 0.983; P = 0.022), (adjusted; OR = 0.982; P = 0.022)].
conclusionThe study revealed a low QOL in mCRC, a notable difference in social functioning, and the GHS among patients with and without mutations. Further research is needed to develop targeted interventions to enhance QOL in patients with KRAS mutation.
