摘要
应用电子计算机 X 线体层摄影(CT)分析了48例肝癌术后复发病例,复发灶出现时间从6月到6年不等,其中6～18个月内复发的占60.4%,2年内占75%。复发以单病灶为主(43.8%),2个病灶次之(20.8%),3～5个占18.8%,5个以上者仅占16.7%。复发以小病灶为特点,≤3cm 者占77.4%,而>5cm 仅有2.7%.CT 主要表现为平扫低密度病灶,增强形式有整个病灶增强和边缘部分增强(80%和20%)。病灶边缘清晰者42.2%。复发灶的 CT 表现与原发性肝癌结节型表现间差异无显著性(P>0.05)。本文还对其中18例再次手术的复发病例与 CT、B 超作了对照分析。CT 的敏感性(90.7%)较 B 超为高(74.4%)。CT 的假阴性率(9.3%)较 B 超为低(25.6%)。病灶大小的估计准确性,两者相近。另外还对肝癌术后随访提出了参考指标。
Forty-eight cases of postoperative recurrence of hepatocellular carcinoma(HCC)are
analysed.The discovery time of recurrence was 6 months to 6 years with peak time be
tween 6 to 18 months(60.4%),Single focus recurrence(43.8%)was most common.
Majority of the lesions was small(≤3cm in diameter)and only 2.7% of the lesions was >5cm.CT findings were low density in all cases in precontrast scan and whole lesion
enhancement(80%)and peripheral enhancement(20%)in postcontrast scan.There was a
well-defined outline in 42.2% of cases.High density lesion in early arterial phase accoun
ted for 40%(2/5).There was no difference in CT appearance between recurrent and pri
mary lesions of HCC.Both CT and ultrasound examinations were performed in 18 cases.
In comparison with operative findings,the accuracy rate of CT diagnosis was higher than
that of ultrasound(90.7% vs 74.4%).The authors propose the indication of postopera
tive CT follow-up examination.
