腹水系一常见症候,鉴别其良、恶性至为重要。我们采用测定腹水中的纤维结合蛋白(Fibronectine简称Fn)及胆固醇(Cholesterol简称Ch)的方法,帮助鉴别,结果甚为满意。临床资料共测定腹水病人51例,其中恶性腹水组35例(肝癌17例,胃癌10例,卵巢癌6例,乳房癌结肠癌各1例),良性腹水组16例(肝硬化)。全部病例均经临床资料(包括内窥镜、B型超声、甲胎蛋白等 Ascites is a common symptom and it is important to distinguish between benign and malignant. We used the method of measuring fibronectin (Fn) and cholesterol (Cholesterol referred to as Ch) in ascitic fluid to help identify, and the results were very satisfactory. A total of 51 patients with ascites were examined for clinical data, including 35 cases of malignant ascites (17 cases of liver cancer, 10 cases of gastric cancer, 6 cases of ovarian cancer, 1 case of breast cancer and 1 case of breast cancer), and 16 cases of benign ascites (cirrhosis). The clinical data of all cases (including endoscope, B-mode ultrasound, alpha fetoprotein, etc.)
