摘要: 目的 探讨不同肿块大小的乳腺导管内癌(ductal carcinoma in situ,DCIS)的临床、病理特点。方法 回顾性分析河北大学附属医院 2011 年 2 月至 2013 年 9 月收治的 78 例 DCIS 病例特点,以肿块大小 1.0 cm 及 3.0 cm 为分界点,进行对比分析。结果 肿块≤1.0 cm 及肿块 1.0~3.0 cm 临床特征差异无统计学意义(P>0.05),而肿块>3.0 cm 与前 2 者相比差异有统计学意义(P<0.05),多表现为微浸润,多灶性比例高以及前哨淋巴结阳性比例高。DCIS与浸润性导管癌(infiltrating ductal carcinoma,IDC)进行病理学指标的差异性分析,ER、PR、Ki67 阳性表达相对低、HER-2 阳性表达相对高(P<0.05),差异有统计学意义,而 IDC 与肿块>3.0 cm 的 DCIS 进行分析,各指标差异无统计学意义(P>0.05)。结论 肿块>3.0 cm 的 DCIS 是一种特殊类型的癌,具有侵袭性,生物学特点更接近于 IDC,治疗推荐按 IDC 方式处理。

Abstract: Objective To explore the clinical and pathological characteristics of ductal carcinoma in situ (DCIS) with tumor size examination. Methods We retrospectively analyzed 78 DCIS cases in Affiliated Hospital of Hebei University from Feb. 2011 to Sep. 2013. A comparative analysis was conducted with the cut-off points of 1.0 cm and 3.0 cm tumor size. Results When tumor size≤1.0 cm and tumor size between 1.0-3.0 cm, the clinical characteristics had no significant difference, when tumor size>3.0 cm, the characteristics were significantly different from the above two (P<0.05) shown as micro infiltration, high multifocal proportion, and high sentinel lymph node positive rate. The variance analysis of pathological indicators of DCIS and IDC showed that the positive expression of ER, PR, Ki67 was relatively low, while the positive expression of HER-2 was relatively high (P<0.05), this difference was significant. When tumor size >3 cm, all the indicators had no significant difference. Conclusion When tumor size>3.0 cm, the DCIS is more aggressive and its biology characteristics are similarly to IDC. The IDC treatment is recommended.
