癌胚抗原(CEA)在结肠直肠癌术后随访中已广泛应用,但对早期诊断和再次手术治疗复发中的价值尚有争论,用CEA作早期复发再治疗的根据以改善预后的可能尚有怀疑。作者回顾1978～1984年87例结直肠癌因局部区域性复发或远处转移再次手术病例。初治手术皆认为是可治疗性的,但初治手术医院、手术范围和术后治疗等皆不相同,再次住院原因亦异。再次术前诊断有临床所见、结直肠内窥镜检和X线检查吻合口、CT、超声腹部和盆腔检查、胸片、骨扫描和实验室检查(血像、CEA、GOT、GPT、AKP、r-GT、BSG、胆红质)。用放射和酶免疫法测
Carcinoembryonic antigen (CEA) has been widely used in the follow-up of colorectal cancer surgery, but there is controversy about the value of early diagnosis and reoperation for recurrence. The use of CEA as a basis for early recurrence and retreatment can improve the prognosis. doubt. The authors reviewed 87 cases of colorectal cancer recurrences due to local recurrence or distant metastases from 1978 to 1984. The initial treatment was considered treatable, but the initial surgery hospital, range of surgery, and postoperative treatment were all different. The reasons for rehospitalization were also different. Preoperative diagnosis of clinical findings, colorectal endoscopy and X-ray anastomosis, CT, ultrasound abdomen and pelvic examination, chest X-ray, bone scan and laboratory examination (blood image, CEA, GOT, GPT, AKP , r-GT, BSG, Bilirubin).
