OBJECTIVE The role of micropapillary pattern (MIP) in EGFR-mutated NSCLC patients with brain metastases (BM) after complete surgical resection still remains unclear. Therefore, a retrospective study was conducted to evaluate the role of MIP in those patients. METHODS This study included 332 stage I-III patients with EGFR-mutant lung adenocarcinoma and complete resection. Patients were classified in four groups: the MIP-positive patients without BM development, the MIP-negative patients without BM development, the MIP-positive patients with BM development and the MIP-negative patients with BM development. Intracranial disease-free survival (iDFS), systemic disease-free survival (DFS) and overall survival (OS) were evaluated. RESULTS The median OS in the whole group was 70 months. The patients with MIP show inferior DFS (13 months vs. 22 months; P < 0.001) and OS (56 months vs. 74 months; P < 0.001). Furthermore, BM development was more likely to be found in patients with MIP (P = 0.001). In addition, the MIP-positive patients showed a significantly shorter iDFS compared with MIP-negative patients (14.5 months vs. 26 months; P < 0.001). Furthermore, the MIP-positive patients had significantly inferior iDFS in both BM as first line development groups (13 months vs. 19 months; P < 0.001) and BM as non-first line development groups (18 months vs. 33 months; P = 0.007). CONCLUSIONS MIP was related to the earlier recurrence and shortened survival time. In addition, MIP was an independent poor prognostic factor for the increase of BM rate and the shortened time of BM development after surgery.

微乳头状病变与EGFR突变型肺腺癌患者手术后脑转移的发展和生存时间的减少有关。

目的在完全手术切除后,EGFR突变的NSCLC脑转移瘤(BM)患者中微乳头状结构(MIP)的作用尚不清楚。因此,进行了一项回顾性研究,以评估MIP在这些患者中的作用。方法该研究纳入332例I-III期EGFR突变型肺腺癌患者,并进行了完全切除。患者分为四组:无BM发育的MIP阳性患者,无BM发育的MIP阴性患者,有BM发育的MIP阳性患者和有BM发育的MIP阴性患者。评估了颅内无疾病生存期(iDFS),全身无疾病生存期(DFS)和总生存期(OS)。结果整个组的中位OS为70个月。MIP患者的DFS较差(13个月vs. 22个月;P <0.001)和OS(56个月vs. 74个月; P <0.001)。此外,在MIP患者中更可能发现BM的发展(P = 0.001)。此外,与MIP阴性患者相比,MIP阳性患者的iDFS显着缩短(14.5个月比26个月; P <0.001)。此外,MIP阳性患者的一线发育组BM的iDFS明显较差(13个月vs. 19个月; P <0.001)和非一线发育组BM的iDFS(18个月vs. 33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。MIP患者更容易出现BM的发展(P = 0.001)。此外,与MIP阴性患者相比,MIP阳性患者的iDFS显着缩短(14.5个月比26个月; P <0.001)。此外,MIP阳性患者的一线发育组BM的iDFS明显较差(13个月vs. 19个月; P <0.001)和非一线发育组BM的iDFS(18个月vs. 33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。MIP患者更容易出现BM的发展(P = 0.001)。此外,与MIP阴性患者相比,MIP阳性患者的iDFS显着缩短(14.5个月比26个月; P <0.001)。此外,MIP阳性患者的一线发育组BM的iDFS明显较差(13个月vs. 19个月; P <0.001)和非一线发育组BM的iDFS(18个月vs. 33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。与MIP阴性患者相比,MIP阳性患者的iDFS显着缩短(14.5个月比26个月; P <0.001)。此外,MIP阳性患者的一线发育组BM的iDFS明显较差(13个月vs. 19个月; P <0.001)和非一线发育组BM的iDFS(18个月vs. 33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。与MIP阴性患者相比,MIP阳性患者的iDFS显着缩短(14.5个月比26个月; P <0.001)。此外,MIP阳性患者的一线发育组BM的iDFS明显较差(13个月vs. 19个月; P <0.001)和非一线发育组BM的iDFS(18个月vs. 33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。001)和BM作为非一线开发组(18个月对33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。001)和BM作为非一线开发组(18个月对33个月; P = 0.007)。结论MIP与早期复发和缩短生存时间有关。此外,MIP是增加BM率和缩短术后BM形成时间的独立不良预后因素。
