DSA在不能手术肝癌诊治中的应用

The Role of DSA in the Diagnosis and Treatment of Inoperable Liver Cancer

本文探讨了DSA对肝癌的诊断价值与治疗用途。通过应用DSA技术与设备对158例临床拟诊为肝癌病例行DSA检查166次,均被确诊为不能手术的肝癌(原发性120例,转移性38例),随即行THAI176次及THAE22次,使癌瘤生长得以控制或缩小者占80.4％。获得随访的135例,半年和1年生存率各为54.8％和41.1％。结果表明,DSA不仅为肝癌的一种可靠的诊断技术,而且提高了THAI及THAE的准确性、安全性与疗效。

From July 1987 to January 1989,158 cases of inoperable liver cancers (120 primary, 38 metastatic) were exam- ined with DSA technique, All tumors had typical malignant signs on DSA,such as neoplastic vessels,interruption of ves- sels, A-V shunt, tumor staining,tumorous thrombosis etc. Once the tumor was believed to be inoperable judging from the DSA findings the catheter remained in position and infusion or embolization was given via the catheter. Transcatheter hepatic artery infusion with anticancer agents solely was performed 176 times and transcatheter embolization with iodol and anticancer agents or gelatin 22 times. Tumors were either put under control or reduced in size in 80.4% of cases, In 135 cases there were follow-up observation,the 0.5- and 1-year survival rates were 54.8% and 41.1% respectively. It is proved that DSA technique is not only reliable in diagnosis,but also valuable in the treatment of inoperable liver can- cers.
