Evaluation of the Plasma Expression Levels of miR-21 and miR-145 as Potential Non-Invasive Biomarkers for Early Detection of Colorectal Cancer.
Article in Asian Pacific journal of cancer prevention : APJCP, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeColorectal cancer (CRC) is one of the most commonly diagnosed cancers in the world. Early detection would be greatly enhanced if accurate and cost-effective diagnostic biomarkers for CRC were accessible. The development of blood tests would evidently lower the screening cost of CRC detection. The aim of the present study was to examine the prospective of plasma miRNAs as non-invasive biomarkers for CRC screening.
methodsThe expressions of miR-21 and miR-145 in the plasma of colorectal adenocarcinomas and normal healthy controls were quantified by using TaqMan miRNA assays. MiRNA expression levels were also correlated with commonly used clinicopathological features of CRC.
resultsOut of 30 CRC patients, 19 were male and 11 were female. The Mean age of patients was 51.3 ±14.6 years. A statistically significant increase in expression of miR-21 was observed in CRC patients' as compared to healthy controls (p<0.001). A significant association between miR-21 expression and age group (p=0.002) was noticed. Also, a statistically significant difference (p=0.015) between miR-21 expression and tumor location in the proximal and distal sites of the colon was observed in CRC patients. Further, a statistically significant downregulation of miR-145 expression was observed in the plasma of CRC patients as compared to healthy controls (p<0.05). This is the first study to report a significant association between miR-21 expression, age group, and tumor location in CRC patients.
conclusionThe present study thus emphasises that the appraisal of miR-21 and miR-145 plasma levels may serve as a promising non-invasive screening tool for the early detection of colorectal cancer.
