ABSTRACT

BACKGROUND:

Esophageal cancer (EC) is a highly lethal disease lacking early detection approaches. We previously identified that OTOP2 and KCNA3 were specifically hypermethylated in circulating cell-free DNA from patients with EC. We then developed a blood-based methylation assay targeting OTOP2 and KCNA3 (named "IEsohunter") for esophageal cancer noninvasive detection. This double-blinded, multicenter, prospective study aimed to comprehensively evaluate its clinical diagnostic performance.

METHODS:

Participants with EC, high-grade intraepithelial neoplasia (HGIN), other malignancies, benign gastrointestinal lesions, or no abnormalities were prospectively enrolled from 5 tertiary referral centers across China. Peripheral blood samples were collected, followed by plasma cell-free DNA methylation analysis using the IEsohunter test based on multiplex quantitative polymerase chain reaction adopting an algorithm-free interpretation strategy. The primary outcome was the diagnostic accuracy of IEsohunter test for EC.

RESULTS:

We prospectively enrolled 1116 participants, including 334 patients with EC, 71 with HGIN, and 711 controls. The areas under the receiver operating characteristic curves of the IEsohunter test for detecting EC and HGIN were 0.903 (95% CI 0.880-0.927) and 0.727 (95% CI 0.653-0.801), respectively. IEsohunter test showed sensitivities of 78.5% (95% CI 69.1-85.6), 87.3% (95% CI 79.4-92.4), 92.5% (95% CI 85.9-96.2), and 96.9% (95% CI 84.3-99.8) for stage I-IV EC, respectively, with an overall sensitivity of 87.4% (95% CI 83.4-90.6) and specificity of 93.3% (95% CI 91.2-94.9) for EC detection. The IEsohunter test status turned negative (100.0%, 47/47) after surgical resection of EC.

CONCLUSIONS:

The IEsohunter test showed high diagnostic accuracy for EC detection, indicating that it could potentially serve as a tool for noninvasive early detection and surveillance of EC.
