    摘要:

    目的 探讨伴有微乳头结构的早期胃癌的临床病理特征。 方法 从常州第二人民医院2006年1月至2016年12月连续收治的447例早期胃癌病例中,筛选出伴有微乳头结构者(微乳头成分≥5%的腺癌)8例(1.8%)纳入观察组,其余439例纳入对照组,对比分析2组在患者年龄、性别构成以及病变大体类型、肿瘤部位、肿瘤大小、浸润深度、脉管侵犯、淋巴结转移、病理分期方面的差异。 结果 2组在患者年龄、性别构成以及病变大体类型、肿瘤部位、肿瘤大小构成方面差异均无统计学意义(P>0.05)。观察组黏膜下层浸润率、脉管侵犯率、淋巴结转移率以及病理分期Ⅱ~Ⅲ期占比分别为100.0%(8/8)、62.5%(5/8)、62.5%(5/8)和25.0%(2/8),对照组分别为52.4%(230/439)、9.1%(40/439)、13.9%(61/439)和5.9%(26/439),差异均有统计学意义(P<0.05)。 结论 伴有微乳头结构的早期胃癌属胃癌的罕见特殊亚型,较无微乳头结构的早期胃癌易侵犯脉管和发生淋巴结转移,病理分期晚。

    Abstract:

    Objective To investigate the clinicopathological features of early gastric cancer (EGC) with micropapillary pattern. Methods In 447 consecutive EGC patients at Changzhou No.2 People′s Hospital admitted from January 2006 to December 2016, 8 (1.8%) with micropapillary adenocarcinoma (≥5%) were enrolled in the observation group and the remaining 439 were included in the control group. Clinicopathologic features including age, gender, gross pattern, tumor location, size, invasion depth, lymphovascular invasion, lymphatic metastasis and pathological stage were analyzed and compared between the two groups. Results There were no significant differences between the two groups in age, gender, gross pattern, tumor location or size (all P>0.05). The observation group showed significantly more frequent submucosal invasion (100.0%, 8/8), lymphovascular invasion (62.5%, 5/8), lymphatic metastasis (62.5%, 5/8), and higher pathological stage (Ⅱ+Ⅲ 25.0%, 2/8) compared with those in the control group, which were 52.4% (230/439), 9.1% (40/439), 13.9% (61/439), and 5.9% (26/439), respectively (all P<0.05). Conclusion EGC with micropapillary pattern is rare with a high liability to lymphovascular invasion, lymphatic metastasis, and higher pathological stage, compared to EGC without micropapillary pattern.
