大肠癌肝转移的早期诊断十分困难。大肠癌主要的致死原因之一是肝转移。若能在手术前早期诊断并行转移性肝癌切除术,可明显提高平均生存期。所以大肠癌肝转移早期诊断不仅是治疗方法的重要选择依据,也是进行肝切除,提高病人生存期的关键所在。本文旨在通过对131例大肠癌血清糖链抗原19-9(CA19-9)测定,探讨其对大肠癌肝转移的诊断价值,并分析CA19-9与癌胚抗原(CEA)同时阳性对肝转移的意义,以期对大肠癌肝转移术前诊断有所启迪。 材料和方法 一,一般资料:131例(男71,女60),大肠癌均经手术病理证实。年龄25～85岁,平均58.6岁。结肠癌67例,直肠癌64例。 二、病理特征:131例大肠癌病理诊断高分化腺
Early diagnosis of liver metastases in colorectal cancer is very difficult. One of the main causes of death from colorectal cancer is liver metastasis. If the early diagnosis of parallel metastatic liver cancer can be performed before surgery, the average survival time can be significantly improved. Therefore, early diagnosis of liver metastases of colorectal cancer is not only an important choice basis for treatment, but also the key to liver resection and improve patient survival. This article aims to determine the value of serum carbohydrate antigen 19-9 (CA19-9) in 131 patients with colorectal cancer, to explore its diagnostic value for liver metastases of colorectal cancer, and analyze CA19-9 and carcinoembryonic antigen (CEA) positive positive for the liver The significance of metastasis in order to enlighten the preoperative diagnosis of colorectal liver metastases. Materials and Methods I. General information: 131 cases (male 71, female 60), and colorectal cancer were confirmed by pathology. Age 25 to 85 years old, average 58.6 years old. There were 67 cases of colon cancer and 64 cases of rectal cancer. Second, pathological features: 131 cases of colorectal cancer pathological diagnosis of well-differentiated glands
