胃癌淋巴结隐匿性微转移的病理形态及免疫组织化学分析
Chinese Journal of Clinical and Experimental Pathology(2006)
Abstract
肿瘤的转移是恶性肿瘤的重要生物学行为,常是导致患者死亡的重要原因,确定淋巴结有无癌转移对肿瘤的治疗和预后有重要意义[1,2].近年来,不少学者采用多种技术手段研究不同类型肿瘤淋巴结隐匿性转移,多数学者认为淋巴结隐匿性转移者其复发率较未有转移者高[3~5].胃癌淋巴结隐匿性转移,尤其是淋巴结隐匿性微转移在临床病理诊断中易漏诊.我们收集76例胃癌根治标本探讨其胃癌淋巴结隐匿性微转移的病理形态学及免疫组化特征.
