Analysis of Ultrasound Signs of Benign and Malignant Tumors of the Ovary and Their Correlation with Clinical Stage and Pathological Grading of Ovarian Cancer
Objective:To investigate the ultrasound signs of benign and malignant lesions of ovarian tumors and their correlation with clinical staging and pathological grading of ovarian cancer.Methods:148 patients with ovarian tumors admitted to our hospital from August 2020 to August 2023 were selected for retrospective analysis,and surgical pathology and pathological biopsy were used as the gold standard for diagnosis,60 patients diagnosed with ovarian cancer were included in the malignant group,and 88 patients diagnosed with benign ovarian tumors were included in the benign group.Ultrasonography was performed on all patients and their ultrasound image characteristics were analyzed.Subsequently,the ultrasound diagnostic parameters of 60 patients with ovarian cancer in different clinical stages and pathological grades were analyzed,and the correlation between ultrasound diagnostic related parameters and ovarian clinical stages and pathological grades was analyzed.Results:The accuracy of ultrasound in the diagnosis of benign ovarian tumors was 86.36％(76/88),while the diagnostic rate of malignant tumors was 88.64％(78/88);There were significant differences in the comparison of RI,PI,EDV,and PSV among patients with different clinical stages.The RI and PI of stage Ⅰ patients were(0.77±0.14)and(1.67±0.24)higher than those of stage Ⅱ patients(0.64±0.15)and(1.25±0.16),stage Ⅲ patients(0.52±0.17)and(0.96±0.16),stage Ⅳ patients(0.41±0.12)and(0.76±0.12).The EDV and PSV of stage Ⅰ patients were(8.63±1.27)cm/s and(16.53±2.53)cm/s lower than those of stage Ⅱ patients(10.25±1.68)cm/s and(18.44±1.58)cm/s Phase Ⅲ patients(12.73±1.79)cm/s and(20.14±2.25)cm/s,and Phase Ⅳpatients(15.51±1.12)cm/s and(23.06±1.98)cm/s(P＜0.05);There were significant differences in the comparison of RI,PI,EDV,and PSV among patients with different clinical stages.The RI and PI of grade Ⅰ patients were(0.81±0.16)and(1.62±0.19)higher than those of grade Ⅱ patients(0.65±0.12)and(0.91±0.22),grade Ⅲ patients(0.47±0.17)and(0.67±0.13).The EDV and PSV of grade Ⅰ pa-tients were(8.32±1.51)cm/s and(15.12±3.33)cm/s lower than those of grade Ⅱ patients(12.75±1.14)cm/s and(21.31±3.14)cm/s Grade Ⅲ patients(15.35±1.79)cm/s and(24.08±2.04)cm/s,(P＜0.05);The Spearman correlation analysis results showed that clinical staging and pathological grading were negatively correlated with RI and PI,but positively correlated with EDV and PSV(P＜0.05).Con-clusion:Ultrasound has important guiding value in the diagnosis of benign and malignant ovarian tumors,and has a significant correla-tion with the clinical staging and pathological grading of ovarian cancer,which is worthy of clinical application and promotion.
