Performing a multivariate Cox analysis including plasma YKL-40 (log transformed and treated as a continuous covariate), serum CA-125 (log transformed and treated as a continuous covariate), FIGO stage (I-IV), residual tumor after surgery (yes or no), and age showed that only plasma YKL-40 (HR = 2.13, 95% CI: 1.40 – 3.25, p = 0.0004) was found of independent prognostic value of overall survival. Here, CHI3L1 is linked to neoplasm.
