目前应用的非损伤性肿瘤分期法常可遗漏胰腺癌根治术后微小癌肿，致使预后不佳。作者采用细胞角蛋白免疫组化技术以检测骨髓内微小转移灶。德国M0nchen大学外科等单位于1992～1997年曾施行胰腺癌切除术169例，其中48例病理证实为胰腺腺癌，术后已生存3个月以上。病理分期计UICC At present, the application of non-invasive tumor staging method can often omit small cancer after radical resection of pancreatic cancer, resulting in poor prognosis. The authors used cytokeratin immunohistochemistry to detect micrometastases in the bone marrow. Germany Department of Surgery, M0nchen University and other units in 1992 ~ 1997 had 169 cases of pancreatic cancer resection, of which 48 cases of pathologically confirmed pancreatic adenocarcinoma, postoperative survival has been more than 3 months. Pathological staging UICC
