摘要
目的:对比分析MSCT、DSA对诊断HCC TACE术后复发的价值。方法:搜集80例HCC TACE术后复发的病例,回顾性对比分析MSCT、DSA对诊断HCC TACE术后复发的价值。结果:80例病例共发现复发灶165个,其中小于0.5cm的复发灶为92个,0.5～1cm的复发灶为52个,大于1cm的复发灶为21个。对于小于0.5cm的复发灶,MSCT的检出率为43.5%(40/92),DSA的检出率为86.9%(80/92),两者具有统计学意义(P<0.05);对于0.5～1cm的复发灶,MSCT的检出率为86.5%(45/52),DSA的检出率为94.2%(49/52),两者差异无统计学意义(P>0.05);对于大于1cm的复发灶,MSCT和DSA检出率均为100%。碘油聚集缺损区内的肿瘤染色DSA显示优于MSCT。结论:HCCTACE术后复发灶以小于0.5cm的为多,MSCT对此类小复发灶(<0.5cm)容易漏诊;DSA为HCC TACE术后随访和诊断术后复发的最好检查方法。
Objective：To analyze comparatively the value of MSCT and DSA in the diagnosis of tumor recurrence in hepatocellular carcinoma（HCC） patients after transcatheter arterial chemoembolization（TACE）.Methods：80 HCC patients with tumor recurrence were collected.The interval time of both examinations didn＇t exceed 10 days in our data.The diagnostic value of MSCT and DSA in the tumor recurrence of HCC treated by TACE with clinical follow-up results was assessed.Results：Among the 165 lesions of tumor recurrence in 80 patients with clinical follow-up results,92 lesions were in diameter less than 0.5cm,52 lesions more than 0.5cm and less than 1cm,and 21 lesions more than 1cm.For the lesions in diameter less than 0.5cm,the detection rate of MSCT was 43.5%（40/92）,while that of DSA was 86.9%（80/92）,there was significant difference between MSCT and DSA（P0.05）.For the lesions with diameter more than 0.5cm and less than 1.0cm,the detection rate of the lesions was 86.5%（45/52） with MSCT,while 94.2%（49/52） with DSA,no significant difference existed between MSCT and DSA（P0.05）.For the lesions with diameter more than 1.0cm,the detection rate of the lesions were 100%（21/21） with MSCT and DSA respectively;tumor stain in the defect zone within the accumulated iodized oil was better shown with DSA than with MSCT.Conclusion：Most lesions of tumor recurrence are less than 0.5cm in our data.For them,diagnosis is easy to be missed by MSCT;DSA can be considered as the best way in follow-up and therapy for HCC patients after TACE.
