Nghiên cứu một số đặc điểm lâm sàng và cận lâm sàng của u buồng trứng trước phẫu thuật

Research to describle the ovarian clinical, paraclinical features before surgery. Objective: To compare the clinical symptoms, ultrasound imaging and serum concentrations of CA 125 between benign and malignan ovarian tumor. There were 447 patients included from 112012 to 12/2012 at NHOG. Results: Benign tumor accounts for 85.9 percent and ovarian cancer was 14.1 percent. Among benign ovarian tumor, the rate of age group 40-49 is highest (22.6 percent). The percentage of malignant group at aged 30-39 years was highest (4 percent), but in the age group 20 years, the percentage of ovarian cancer is highest (12/34). In the benign group, abdominal pain accounted for 44.3 percent was highest, followed by a combination 2 or more symptoms group (16.3 percent). In the malignant group, the combination of more than 2 common symptoms is the most (10.2 percent). 62.9 percent of benign group had a concentration of serum CA125 is less than 35UI/ml while all patients in the malignant group is higher than 35UI/ml and most of them (43/74 cases) exceed 394 UI/ml. There are 19 cases that ultrasound loss diagnosis of the ovarian tumor (4.2 percent) but accurately diagnose for 45 cases of malignant tumors (10.1 percent). The PPV was 95.7 percent. The rate of false positive diagnosis of benign tumor was 3.9 percent and the rate of false negatives was 2.3 percent. Diagnosis of malignant ovarian tumors with a false positive rate of 12.1 percent and 4.8 percent for false negatives. The research results have been compared and discussed.
