目的 盐酸埃克替尼和多西他赛均为二线治疗晚期肺腺癌的有效药物,因盐酸埃克替尼上市时间较短,尚罕见其二线治疗肺腺癌总生存期相关数据的可靠报道.本研究以总生存期为主要观察指标,旨在比较盐酸埃克替尼与多西他赛二线治疗晚期肺腺癌的疗效及安全性.方法 回顾性分析郑州大学第一附属医院2011-10-01-2014-04-01收治的121例既往经一线含铂类化疗失败的晚期肺腺癌患者临床资料,其中79例口服盐酸埃克替尼(125mg,3次/d),42例静脉滴入多西他赛(75 mg/m2,d1,21d为1个周期,4~6个周期),直至病情进展或出现不能耐受的不良反应后行最佳支持治疗.主要观察终点为无进展生存期(progress free survival,PFS)、总生存期(overall survival,OS),次要终点为客观有效率(overall response rate,ORR)、疾病控制率(disease control rate,DCR)和不良反应.结果 盐酸埃克替尼表皮生长因子受体(epidermal growth factor receptor,EGFR)状态未知组37例可评价,其中部分缓解(partial response,PR)4例(10.8%),疾病稳定(stable disease,SD)18例(48.7%),疾病进展(progressive disease,PD)15例(40.5%).多西他赛组EGFR状态未知的42例可评价病例中,PR 6例(14.3%),SD 20例(47.6%),PD 16例(38.1%).2组ORR分别为10.8%和14.3%,x2=0.015,P=0.901;DCR分别为59.5%和61.9%,x2=0.049,P=0.824;中位PFS分别为2.9和3.2个月,x2=0.191,P=0.662;中位OS分别为10.0和8.2个月,x2=1.249,P=0.264.埃克替尼EGFR突变组42例可评价病例中,PR 17例(40.5%),SD 21例(50.0%),PD 4例(9.5%).与埃克替尼EGFR状态未知组相比,ORR分别为40.5%和14.3%,x2=8.870,P=0.003;DCR分别为90.5%和59.5%,x2=10.360,P=0.001;中位PFS分别为12.2和2.9个月,x2=20.178,P<0.001;中位OS分别为19.5和10.0个月,x2=11.245,P=0.001;差异均有统计学意义.服用埃克替尼的患者出现严重不良反应的发生率较低(x2=9.700,P=0.002),安全性更好.结论 晚期肺腺癌EGFR状态未知患者二线应用盐酸埃克替尼治疗与多西他赛单药化疗的疗效相当,但不良反应较少;而EGFR突变的患者二线应用盐酸埃克替尼可以明显延长总生存期,得到更大的临床获益. 相似文献

BackgroundIcotinib has been previously shown to be non-inferior to gefitinib in non-selected advanced non-small-cell lung cancer patients when given as second- or further-line treatment. In this open-label, randomized, phase 3 CONVINCE trial, we assessed the efficacy and safety of first-line icotinib versus cisplatin/pemetrexed plus pemetrexed maintenance in lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) mutation.Patients and methodsEligible participants were adults with stage IIIB/IV lung adenocarcinoma and exon 19/21EGFR mutations. Participants were randomly allocated (1 : 1) to receive oral icotinib or 3-week cycle of cisplatin plus pemetrexed for up to four cycles; non-progressive patients after four cycles were maintained with pemetrexed until disease progression or intolerable toxicity. The primary end point was progression-free survival (PFS) assessed by independent response evaluation committee. Other end points included overall survival (OS) and safety.ResultsBetween January 2013 and August 2014, 296 patients were randomized, and 285 patients were treated (148 to icotinib, 137 to chemotherapy). Independent response evaluation committee-assessed PFS was significantly longer in the icotinib group (11.2 versus 7.9 months; hazard ratio, 0.61, 95% confidence interval 0.43–0.87;P = 0.006). No significant difference for OS was observed between treatments in the overall population or inEGFR-mutated subgroups (exon 19 Del/21 L858R). The most common grade 3 or 4 adverse events (AEs) in the icotinib group were rash (14.8%) and diarrhea (7.4%), compared with nausea (45.9%), vomiting (29.2%), and neutropenia (10.9%) in the chemotherapy group. AEs (79.1% versus 94.2%;P < 0.001) and treatment-related AEs (54.1% versus 90.5%;P < 0.001) were significantly fewer in the icotinib group than in the chemotherapy group.ConclusionsFirst-line icotinib significantly improves PFS of advanced lung adenocarcinoma patients withEGFR mutation with a tolerable and manageable safety profile. Icotinib should be considered as a first-line treatment for this patient population. 相似文献

Objective: To evaluate the efficacy and safety of icotinib hydrochloride in patients with advanced non-small cell lung cancer (NSCLC). Methods: A total of 89 patients with stage ⅢB or IV NSCLC received icotinib at a dose of 125 mg administered 3 times a day. Icotinib treatment was continued until disease progression or development of unacceptable toxicity. Results: A total of 89 patients were assessable. In patients treated with icotinib, the overall response rate (RR) was 36.0% (32/89), and the disease control rate (DCR) was 69.7% (62/89). RR and DCR were significantly improved in patients with adenocarcinoma versus non-adenocarcinoma (P<0.05). The symptom improvement rate was 57.3% (51/89), and the main symptoms improved were cough, pain, chest distress, dyspnea, and Eastern Cooperative Oncology Group performance status. The main toxic effects were rash [30/89 (33.7%)] and diarrhea [15/89 (16.9%)]. The level of toxicity was typically low. Conclusions: The use of icotinib hydrochloride in the treatment of advanced NSCLC is efficacious and safe, and its toxic effects are tolerable. 相似文献

Survival status and prognostic factors of leptomeningeal metastasis from lung adenocarcinoma北大核心CSCD
Objective: To investigate the survival status and prognostic factors of patients with leptomeningeal metastasis (LM) from lung adenocarcinoma. Methods: The survival rate and prognostic factors of 65 patients with LM from lung adenocarcinoma, who had complete follow-up data, were retrospectively analyzed. Results: The median survival time of the 65 patients was 7.4 months,and the 1-year survival rate was 6.2% (4/65). Univariate analysis demonstrated that gender, age, smoking history, timing of LM and whether in combination with brain metastasis had no significant correlations with overall survival (all P > 0.05); while the Eastern Cooperative Oncology Group (ECOG) performance status (PS) score, ventriculo-peritoneal (V-P) shunt, epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) targeted therapy, systemic chemotherapy (SC), whole-brain radiotherapy (WBRT), clinical signs of LM and EGFR gene status were associated with the overall survival (all P < 0.05). Multivariate analysis showed that EGFR gene status, ECOG PS score, SC and V-P shunt were independent prognostic factors of the prognosis of patients with LM from lung adenocarcinoma (all P < 0.05). Conclusion: The overall prognosis of patients with LM from lung adenocarcinoma is poor. The prognosis of patients with LM bearing EGFR mutation is relatively good. EGFR-TKI targeted therapy, SC and V-P shunt can prolong the survival time and improve the prognosis of patients with LM metastasis from lung adenocarcinoma.

Leptomeningeal metastases (LM) occur in 5–10% of patients with solid tumors and are associated with a dismal prognosis. We
describe LM from lung adenocarcinoma harboring a mutation in the epidermal growth factor receptor (EGFR) gene that confers
sensitivity to the EGFR tyrosine kinase inhibitors (EGFR-TKIs) erlotinib and gefitinib. The CSF concentration of EGFR-TKIs
achieved by standard daily dosing may be insufficient for therapeutic effect. However, intermittent (pulsatile) high dose
administration (1000–1500 mg/week) achieves a higher CSF concentration than standard dosing, and successfully controlled LM
in this patient. 相似文献
