Correlation Study between Ultrasonography Parameters and Lymph Node Metastasis after Laparoscopic Surgery in Patients with Early Ovarian Cancer
Objective:To investigate the correlation between ultrasonographic parameters and lymph node metastasis after laparoscopic surgery in patients with early-stage ovarian cancer.Method:The clinical data of 50 early ovarian cancer patients who developed lymph node metastasis within 1 year after laparoscopic surgical treatment in the Seventh Affiliated Hospital of Xinjiang Medical University from March 2021 to October 2022 were retrospectively analyzed,and they were set as the lymph node metastasis group,and 50 early ovarian cancer patients who did not develop lymph node metastasis within 1 year after receiving laparoscopic surgical treatment in the same period were selected as the non-lymph node metastasis group.The clinical data of the two groups of patients were collected,and the differences in ultrasonography parameters between the two groups were compared.The correlation between ultrasonography parameters and their postoperative lymph node metastasis in patients with early-stage ovarian cancer was analyzed,and the diagnostic efficacy of quantitative ultrasonography parameters on lymph node metastasis after laparoscopy in patients with early-stage ovarian cancer was analyzed by using ROC curve.Result:Compared with the basal intensity and peak time of patients in the non-lymph node metastasis group,the basal intensity of patients in the lymph node metastasis group was significantly lower and the peak time was significantly shorter,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the comparison of ultrasonographic parameters such as perfusion time,enhancement intensity,arrival time and peak intensity between the two groups(P>0.05).Spearman correlation analysis showed that ultrasonography parameters such as base intensity and time to peak were negatively correlated with lymph node metastasis within 1 year after laparoscopy in patients with early-stage ovarian cancer.The ROC results showed that the AUC values of base intensity and time to peak,alone and in combination,for detecting lymph node metastasis within 1 year after laparoscopy in patients with early-stage ovarian cancer were 0.731,0.796 and 0.855,respectively.Conclusion:Basal intensity and time to peak have high correlation with lymph node metastasis within 1 year after laparoscopic surgery in patients with early-stage ovarian cancer,and the combined detection of basal intensity and time to peak can improve the efficacy of predicting lymph node metastasis within 1 year after laparoscopic surgery in patients with early-stage ovarian cancer.
