Objective:To study the prognostic value of preoperative neutrophil to lymphocyte ratio(NLR) and postoperative NLR in patients with oral squamous cell carcinoma(OSCC). Methods:One hundred and twenty-three patients with primary OSCC undergoing radical operation of oral cancer in our hospital from October 2012 to January 2020 were selected. The data of blood routine of all the patients last time before operation and 3 months after operation were collected. The effects of preoperative and postoperative NLR on overall survival(OS) and disease-free survival(DFS) of OSCC patients were analyzed by Cox regression analysis and Kaplan-Meier(K-M) survival curve. Results:The area under the curve(AUC) of preoperative NLR was 0.670(0.570-0.770), and the best cutoff value was 2.74. The AUC of postoperative NLR was 0.643(0.544-0.743), and the best cutoff value was 3.13. The rate of postoperative wound infection and chemoradiotherapy in patients with NLR ≥ 3.13 group was higher than that in patients with NLR<3.13 group, and postoperative Hb was lower than that in patients with NLR<3.13 group, the differences being statistically significant(all P<0.05). The median of OS and DFS in the low preoperative NLR group was higher than that in the high preoperative NLR group, and the differences between the two groups were statistically significant(P<0.05). The median of OS of low NLR group was higher than that of high NLR group(P<0.05). The median of DFS of low NLR group was higher than that of high NLR group(P>0.05). Cox regression analysis showed that tumor size(T3-T4/T1-T2), clinical stage(Ⅲ-Ⅳ/Ⅰ-Ⅱ), pathological stage(Ⅱ-Ⅲ/Ⅰ), preoperative NLR ≥ 2.74 and postoperative NLR ≥ 3.13 were independent prognostic factors of OS, and their HR values were 2.706, 2.949, 2.219, 2.015 and 1.985, respectively. Clinical stage(Ⅲ-Ⅳ/Ⅰ-Ⅱ), pathological stage(Ⅱ-Ⅲ/Ⅰ), cervical lymph node metastasis, radiotherapy or chemotherapy, preoperative NLR ≥ 2.74 were independent influencing factors of DFS, and their HR values were 1.687, 2.451, 1.912, 0.696 and 1.830, respectively. Conclusion:Preoperative and postoperative NLRs have certain predictive value for poor prognosis. Preoperative NLR ≥ 2.74 is an independent influencing factor for OS and DFS in patients with OSCC after radical resection, and postoperative NLR ≥ 3.13 is an independent influencing factor for OS after radical operation. |
