Abstract
BACKGROUND

The diagnostic value of combined methylated branched chain amino acid transaminase 1 (BCAT1)/IKAROS family zinc finger 1 (IKZF1) in plasma for colorectal cancer (CRC) has been explored since 2015. Recently, several related studies have published their results and showed its diagnostic efficacy.

AIM

To analyze the diagnostic value of methylated BCAT1/IKZF1 in plasma for screening and postoperative follow-up of CRC.

METHODS

The candidate studies were identified by searching the PubMed, Embase, Cochrane Library, CNKI, and Wanfang databases from May 31, 2003 to June 1, 2023. Sensitivity, specificity, and diagnostic accuracy were calculated by merging ratios or means.

RESULTS

Twelve eligible studies were included in the analysis, involving 6561 participants. The sensitivity of methylated BCAT1/IKZF1 in plasma for CRC diagnosis was 60% [95% confidence interval (CI) 53-67] and specificity was 92% (95%CI: 90-94). The positive and negative likelihood ratios were 8.0 (95%CI: 5.8-11.0) and 0.43 (95%CI: 0.36-0.52), respectively. Diagnostic odds ratio was 19 (95%CI: 11-30) and area under the curve was 0.88 (95%CI: 0.85-0.91). The sensitivity and specificity for CRC screening were 64% (95%CI: 59-69) and 92% (95%CI: 91-93), respectively. The sensitivity and specificity for recurrence detection during follow-up were 54% (95%CI: 42-67) and 93% (95%CI: 88-96), respectively.

CONCLUSION

The detection of methylated BCAT1/IKZF1 in plasma, as a non-invasive detection method of circulating tumor DNA, has potential CRC diagnosis, but the clinical application prospect needs to be further explored.

Core Tip: DNA methylation, a commonly used target for detecting ctDNA in plasma, is often explored as diagnostic biomarker of cancer. Here, the present study systematically analyzed 12 studies including 6561 individuals to assess the diagnostic value of methylated branched chain amino acid transaminase 1 (BCAT1)/ IKAROS family zinc finger 1 (IKZF1) in plasma for colorectal cancer (CRC) through meta-analysis. The sensitivity and specificity of methylated BCAT1/IKZF1 in plasma for CRC diagnosis were 60% [95% confidence interval (CI) 53-67] and 92% (95%CI: 90-94), respectively. The detection of methylated BCAT1/IKZF1 has potential in CRC diagnosis, but the clinical application prospect needs to be explored.
