美国临床肿瘤学会于1997年11月7日通过了“乳腺癌和结直肠癌的肿瘤标志物使用准则”。该准则是经评论委员会对1994年至1997年7月间的有关文献进行讨论一致认可的。 结直肠癌:①不推荐将癌胚抗原(CEA)测定用于筛查结直肠癌。②如若CEA测定能有助于结直肠癌分期和外科治疗计划的制定,则可在术前进行检测。尽管术前CEA升高(>5mg/ml)可能与预后不良相关,但无足够证据支持以CEA来决定是否给病人辅助治
On November 7, 1997, the American Society of Clinical Oncology adopted the Guidelines for the Use of Tumor Markers for Breast and Colorectal Cancer. The guidelines were unanimously approved by the Review Committee for discussion of relevant documents from 1994 to July 1997. Colorectal Cancer:1 Carcinoembryonic antigen (CEA) assays are not recommended for the screening of colorectal cancer. 2 If CEA measurements can help in the development of colorectal cancer staging and surgical treatment plans, they can be tested before surgery. Although elevated preoperative CEA (>5 mg/ml) may be associated with poor prognosis, there is insufficient evidence to support the decision to use CEA to assist patients
