ObjectiveTo evaluate the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) of preoperation (L/H value for short) and the pathological staging of colorectal cancer. MethodsThe clinical data of 187 patients with colorectal cancer who treated in PLA General Hospital from July 2009 to June 2014 were analyzed retrospectively. ResultsThere were statistical significance in L/H value among different TNM stagings, N stagings, and M stagings (P<0.05):L/H value of TNM Ⅳ staging was higher than those of TNM Ⅰ, Ⅱ, and Ⅲ staging, L/H values of N1 staging and N0 staging were lower than that of N2 staging, L/H value of M1 staging was higher than that of M0 staging. However, there was no statistical significance in L/H value among different T stagings of colorectal cancer (P>0.05). Logistic regression results showed that L/H value were positively associated with TNM staging (OR=4.34, 95% CI:2.837-6.644, P<0.000 1), T staging (OR=1.72, 95% CI:1.175-2.512, P=0.005 3), N staging (OR=2.15, 95% CI:1.422-3.254, P=0.000 3), and M staging (OR=3.04, 95% CI:1.733-5.332, P=0.000 1) of colorectal cancer, and patient with higher L/H value took more risk of progression of tumor, lymph node metastases, and distant metastasis. ConclusionsRaise of preoperative L/H value is an independent risk factor for the progression of TNM staging, T staging, N staging, and M staging in colorectal cancer.
