摘要 目的:探讨80例DukesB期大肠癌淋巴结微转移状态及其与临床病理因素与预后的关系.方法:对80例DukesB期大肠癌淋巴结行间断连续切片结合细胞角蛋白20抗体免疫组织化学染色方法检测淋巴结微转移,并对全部患者进行随访.结果:大肠癌淋巴结微转移与性别、年龄、肿瘤部位、大体分型、以及肿瘤最大径长无关,而与肿瘤的分化程度和肿瘤侵犯肠周径有关;微转移阳性组5a生存率为36.7%,微转移阴性组5a生存率为72.2%,经Log-Rank检验差异有统计学意义(P<0.01),微转移阳性组与阴性组复发率分别为75%和28.8%,差异有统计学意义(P<0.01).结论:间断切片法结合CK20免疫组织化学方法有助于检出DukesB期大肠癌淋巴结微转移,增加每个淋巴结的切片数量有助于提高微转移的检出率;低分化及癌肿侵犯肠周径>3/4者易发生淋巴结微转移:淋巴结微转移阳性组与阴性组的生存率与复发率有显著差异.
