微乳头状癌临床及病理特点的相关性研究

The Biological Behavior of Micro Papillary Carcinoma of the Clinicaland Pathological Relationship

目的探讨浸润性微乳头状癌(IMPC)的临床及病理特点的相关性。方法对52例IMPC的病理组织学及预后进行观察。结果 IMPC发生率为4.7%,2年生存率为73.1%,5年生存率为42.3%(22/52);52例IMPC病理学观察肿瘤组织中均可见比例不等的典型微乳头结构,其中53.8%可见高度淋巴管侵袭,76.9%可见淋巴结转移。结论 IMPC具有淋巴管侵犯和淋巴结转移率较高、预后极差的生物学行为。

Objective To investigate the relationship between the biological behavior and clinical pathology of invasive papillary carcinoma（IMPC）.Methods Histopatbology and prognosis of 52 cases of IMPC were observed.Results The incidence of IMPC rate was 4.7%, 2 years survival rate was 73.1%, 5 year survival rate was 42.3%, 52 cases of IMPC and pathological study were observed in tumor tissues were visible ratio ranging from typical micropapillary structure, which 53.8% highly visible lymphatic duct invasion, 76.9% visible lymph node metastasis.Conclusion IMPC has the biological behavior of lymphatic invasion and lymph node metastasis rate, prognosis.
