Using univariate analysis, high CHI3L1 expression (HR 2.32, 95% confidence interval (CI): 1.58–3.41, p < 0.001), advanced stage (HR: 2.46, 95% CI: 1.40 − 4.31, p = 0.002), high-grade (HR: 1.88, 95% CI: 1.10 − 3.20, p = 0.019) and residual tumor size > 1 cm after debulking surgery (HR: 1.91, 95% CI: 1.34 − 2.72, p < 0.001) were risk factors for recurrence. Here, CHI3L1 is linked to neoplasm.
