The median follow-up time was 29.04 months (range 6–60 months), and a cut-off value of the 50th percentile of AChE (1.801 mU/mg protein) and BChE (2.967 mU/mg protein) was set-up when comparing activity values in tumours with OS and DFS rates of the study population. Here, ACHE is linked to neoplasm.
