ARCH PATHOL LAB MED:胆总管和胆囊管侵犯在远端胆管癌中的临床病理和预后意义?

2020-06-25 MedSci原创 MedSci原创

目前,关于胆囊和胆囊管浸润在远端胆管癌(DBDC)中的作用尚不清楚,本研究试图明确DBDC患者胆囊或CD侵犯的特点及预后意义。研究人员对258例切除的DBDCs进行了器官侵犯类型和临床病理特征的评估。

目前,关于胆囊和胆囊管浸润在远端胆管癌(DBDC)中的作用尚不清楚,本研究试图明确DBDC患者胆囊或CD侵犯的特点及预后意义。研究人员对258例切除的DBDCs进行了器官侵犯类型和临床病理特征的评估。

研究结果显示,CD侵犯(N = 31)常伴有胰腺和/或十二指肠侵犯(31,74%中的23例),表现为间质浸润(31,52%中的16例)和导管内癌(31,48%中的15例)。仅2例患者在胆囊颈部出现侵犯并导管内癌变。相反,所有胰腺(175例)和十二指肠(83例)的侵犯都是通过间质浸润发生的。CD侵犯与较大的肿瘤大小(P = .001)、胆管边缘阳性(P = .001)、周围神经侵犯(P = .04)和较高的N类相关(P = .007)。胰腺或十二指肠损伤患者的生存率明显低于无胰腺损伤的患者(中位31.0月对93.9月)或十二指肠损伤的患者(中位27.5月对56.8月,P < .001)。而侵犯胆囊或CD者的生存时间无显著差异(P = .13)。同时有胆囊/CD和胰腺/十二指肠侵犯的患者的生存率明显低于无器官侵犯的患者(P < .001)。

研究结果表明,胆囊侵犯在DBDCs少见,颈部侵犯合并导管内癌变。CD侵犯以间质浸润和导管内癌变为主,而胰腺和十二指肠侵犯均以间质浸润为主。胆囊和/或CD侵犯不影响DBDC患者的生存率,而胰腺和十二指肠侵犯影响生存率。因此,这些存活率的差异可能源于DBDCs的侵袭方式不同。
