Regarding analyses with overall survival as endpoint, BChE (p < 0.003), clinical tumor stage (p < 0.001), preoperative UICC classification (p < 0.001), grading (p < 0.001), pT (p < 0.001), pN (p < 0.003), and lymph node ratio (p < 0.001) were significantly related. Here, BCHE is linked to neoplasm.
