为评价和比较临床上检测结直肠癌肝转移的CT扫描和某些试验的敏感性和特异性,作者进行了回顾性研究。作者复习1985年1月1日至1986年12月30日南方伊利诺斯大学附属医院手术治疗的420例结直肠癌病人的病历。其中33例(7.9％)术前30天内进行了腹部和盆腔CT扫描。作者将CT报告同手术发现进行比较。术前测定了LDH和CEA水平。全部33例有术前LDH、CEA测
In order to evaluate and compare the sensitivity and specificity of CT scans and certain tests for the clinical detection of colorectal liver metastases, the authors performed a retrospective study. The authors reviewed the medical records of 420 patients with colorectal cancer who were treated surgically at the University Hospital of Illinois at Southern from January 1, 1985 to December 30, 1986. Thirty-three patients (7.9%) had abdominal and pelvic CT scans within 30 days before surgery. The authors compared CT findings with surgical findings. LDH and CEA levels were determined preoperatively. All 33 patients had preoperative LDH and CEA measurements
