There were significant differences between preoperative PNI and BMI, platelet, NLR, PLR, LMR, postoperative recurrence, surgical mode and Fuhrman grade (P < 0.05), but there were no significant differences with age, gender, diabetes, hypertension, hemoglobin, tumor size, Ki-67, CRP, tumor necrosis, positive surgical margin, pathological type, and AJCC stage (P > 0.05), as shown in Table 1. This evidence concerns the gene CRP and hypertensive disorder.
