ABSTRACT
Objective To investigate the value of short diameter of lymph nodes combined with neutrophil to lymphocyte ratio(NLR)in evaluating lymph node metastasis of cervical cancer by enhanced CT.Methods A total of 82 patients with cervical cancer were selected and divided into metastatic group(n=13)and non-metastatic group(n=69)according to whether lymph node metas-tasis occurred.The clinicopathological features of the two groups were compared,and the relationship between NLR and clinicopath-ology was analyzed.Logistic regression was used to analyze the influencing factors of lymph node metastasis of cervical cancer.The short diameter of lymph nodes and serum NLR were compared between the two groups.Receiver operating characteristic(ROC)curve,DeLong test and compare the area under the curve(AUC)analysis was used to evaluate the value of lymph node metastasis in cervical cancer.The diagnostic efficacy of the above indexes were compared between the two groups.Results The short diameter of lymph nodes and NLR in the metastatic group were(0.686±0.120)cm and 2.23±0.41 respectively,while thosein the non-metastatic group were(0.602±0.106)cm and 1.76±0.30 respectively.The difference between the two groups was statistically signifi-cant(P<0.05);There was no significant difference in age,growth pattern and vascular infiltration between the metastatic group and the non-metastatic group(P>0.05).There were significant differences in clinical stage,maximum diameter of tumor,NLR and short diameter of enhanced CT lymph nodes(P<0.05);The NLR was related to clinical stage,pelvic lymph node metastasis,and the short diameter of lymph nodes on enhanced CT scan(P<0.05);Clinical stage Ⅲ,maximum diameter of tumor≥4 cm,NLR>1.80 and short diameter of enhanced CT lymph nodes≥0.632 cm were independent risk factors for cervical cancer lymph node metastasis(P<0.05);The ROC curve analysis showed that the AUC of the combined detection of cervical cancer was 0.871,higher than that of the enhanced CT lymph nodes short diameter and serum NLR(0.645,0.795),and its specificity was better than that of the independent detection.The best cutoff values of the enhanced CT lymph nodes short diameter and serum NLR were 0.630 cm and 1.91,respectively.Conclusion The short diameter of lymph nodes and the serum NLR can predict lymph node metastasis of cervical cancer,and the combined detection can improve the evaluation efficiency.
