摘要
目的探讨结直肠癌中淋巴管的分布特点、增殖状态及其与转移和预后的关系。方法采用淋巴管特异标记podoplanin对96例结直肠癌及其相应正常组织进行免疫组织化学染色检测微淋巴管密度,以CD34标记血管检测微血管密度作为对比,并分别与Ki-67进行双标免疫组织化学染色检测淋巴管和血管增殖活性,结合结直肠癌临床病理参数和预后分析。结果结直肠癌中心及浅表部淋巴管多为闭锁的条索状,边缘区淋巴管多呈管样扩张状。结直肠癌边缘区淋巴管密度(51.2±25.5)及较正常结直肠组织(29.4±9.0)和肿瘤其他区域显著性增高(P<0.01),并且其淋巴管内皮Ki67指数(0.23±0.17)也较其他区域显著性增高(P<0.05)。结直肠癌边缘区微淋巴管密度与淋巴管受累、淋巴结转移、远处器官转移及预后密切相关(P<0.01或P<0.05)。结论结直肠癌组织中存在新生淋巴管,且主要分布于肿瘤边缘区,癌周围淋巴管密度增加与癌细胞转移相关,结直肠癌边缘区微淋巴管密度测定对评估其淋巴结转移和预后判断可能具有意义。
