目的 探讨影响表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)治疗晚期非小细胞肺癌(NSCLC)患者疗效的临床因素.方法 对2005年1月至2006年12月接受EGFR-TKI治疗的166例晚期NSCLC患者的临床资料进行回顾性分析,其中ⅢB期62例,Ⅳ期104例,均有可测量的临床病灶.结果 166例NSCLC患者中,119例取得临床获益,疾病控制率(DCR)为71.7%.患者的性别、年龄、吸烟情况、病理类型、应用EGFR-TKI时是否存在骨脑转移、应用EGFR-TKI治疗的时机以及诊断时血清乳酸脱氢酶(LDH)水平不影响EGFR-TKI的治疗效果.在126例有血清癌胚抗原(CEA)水平的NSCLC患者中,84例患者CEA高于正常水平,诊断时血清CEA水平高者和正常者的DCR分别为79.8%和59.5%(P=0.016).在临床获益患者中,吸烟状态和诊断时CEA水平影响无进展生存期(PFS),其中不吸烟者的PFS为(9.57±6.75)个月,轻度吸烟者为(4.86±3.44)个月,重度吸烟者为(5.25±4.34)个月(P=0.007);诊断时CEA水平高者的PFS为(9.45±7.48)个月,CEA水平正常者为(6.52±4.46)个月(P=0.036).结论 EGFR-TKI治疗晚期NSCLC是安全有效的,CEA水平高的患者更易从EGFR-TKI治疗中获益.
Abstract:
Objective To explore the clinical factors affecting the sensitivity of EGFR-TKI treatment in advanced non-small cell lung cancer. Methods Clinical data were retrospective analyzed to determine the clinical factors affecting the outcome of 166 patients with advanced non-small cell lung cancer who received EGFR-TKI treatment in our hospttal from January of 2005 to December of 2006. Results One hundred and nineteen patients benefited from EGFR-TKI treatment in the total of 166 patients and the disease control rate was 71.7%. Among the factors analyzed, sex, age, smoking, pathological type, brain and bone metastasis or not when EGFR-TKI was used, the time using EGFR-TKI and the level of LDH at the time of diagnosis had no significant effect on the clinical benefit rate. Among the 126 patients with serum CEA assayed at diagnosis, 84 cases had a higher serum CEA level. Compared with the patients with normal serum CEA level, the patients with a higher serum CEA level benefited more easily from EGFR-TKI therapy, with a disease control rate of 79.8% and 59.5%, respectively (P = 0. 016). Among the patients who got benefits from EGFR-TKI treatment, smoking and the CEA level at diagnosis had effects on the duration of progression-free survival. The progression free survivals were 9.57 ± 6.75 months in non-smokers, 4.86 ±3.44 months in light-smokers and 5.25 ± 4.34 months in heavy-smokers (P = 0.007 ). The progression free survival was 9.45 ± 7.48 months in the group with a higher serum CEA level and 6.52 ± 4.46 months in the group with normal serum CEA level (P = 0.036). Conclusions In patients with advanced non-small cell lung cancer, EGFR-TKIs treatment is safe and effective. The patients with high CEA level are prone to benefit from it.  相似文献

脑转移是肺癌患者疾病进展的一个普遍以及灾难性的后果。表皮生长因子受体-酪氨酸激酶抑制剂(EGFR—TKI)通过降低S期细胞的比例、减少肿瘤血管形成、引起凋亡增加、抑制分次照射中肿瘤细胞再增殖、降低辐射抗性等途径,发挥对放疗的增敏作用。同期放疗联合EGFR—TKI(如吉非替尼等)治疗非小细胞肺癌(NSCLC)脑转移患者的临床研究显示其有更高的有效率、更长的生存期。EGFR-TKI自身毒性相对较低,患者发生不良反应后经对症治疗多数可好转,与放疗联合应用时对放疗影响较小。  相似文献

目的 研究使用表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKIs)前后进展期非小细胞肺 癌(NSCLC)患者血清癌胚抗原(CEA)水平的变化,在预测患者疗效和预后中的价值.方法 采用电化学发光免疫法检测75例应用EGFR-TKIs前后NSCLC患者血清CEA水平的变化,评价其与患者临床疗效和预后的关系.结果 75例进展期NSCLC患者经EGFR-TKIs治疗4周后,完全缓解(CR)1例(1.3%),部分缓解(PR)17例(22.7%),疾病稳定(SD)31例(41.3%),疾病进展(PD)26例(34.7%).全组患者的客观有效率(ORR)为24.0%,疾病控制率(DCR)为65.3%.全组患者的中位生存时间(MST)为8.1个月.影像学缓解(OR)与SD患者的MST相似(10.5个月和8.7个月,P=0.06),二者均长于PD患者(6.3个月,均P<0.001).疾病控制(DC)与OR患者的MST相似(9.3个月和10.5个月,P=0.358),却长于PD患者(P<0.001).血清CEA下降水平≥32%对诊断DC的敏感度和特异度分别为88.2%和90.6%.血清CEA下降水平≥32%者的MST与其水平下降≥61%者相似(9.5个月和10.5个月,P=0.370),但却明显长于其下降水平<32%者(6.7个月,P<0.001).Cox多因素分析结果 显示,血清CEA水平下降≥32%、血清CEA水平下降≥61%、DC和PS评分是影响患者预后的独立因素,而OR则与患者的预后无关.结论 对于进展期NSCLC患者,DCR较ORR更适合作为判定EGFR-TKIs疗效和预测预后的指标.血清CEA水平下降≥32%有可能成为判定EGFR-TKIs疗效和预测预后较可靠的指标之一.
Abstract:
Objective The aim of this study was to detect the pre- and post-treatment serum carcinoembryonic antigen (CEA) levels after 4 weeks of EGFR-TKIs treatment in advanced non-small cell lung cancer (NSCLC) patients to evaluate the clinical value of CEA in the prediction of chemotherapy response and prognosis in those patients. Methods Pre- and post-treatment serum CEA levels of the patients were measured with immunoradiometric kits after 4 weeks of EGFR-TKIs treatment to evaluate the relationship between chemotherapy response and prognosis. Results After 4 weeks of EGFR-TKIs treatment, one patient in the total of 75 patients (1.3%) achieved complete response (CR), 17 patients (22.7%) achieved partial response (PR), 31 patients (41.3%) achieved disease stable (SD) and 26 patients had progressive disease (PD). The radiological objective response rate(ORR) and disease control rate (DCR) were 24.0% and 65.3%, respectively. The median survival time (MST) of all patients was 8.1 months. The MST of SD patients was similar to that in the OR patients (P=0.06), but both longer than that in the PD patients (P<0.001). The MST of DC patients was similar to that in OR patients (P=0.358), but longer than that in PD patients (P<0.001). Serum CEA levels decreased ≥32% and ≥61% were closely related with the objective response and disease control. The median survival time (MST) of patients with serum CEA decreased ≥32% was longer than those with CEA decreased <32% (9.5 months vs 6.7 months,P<0.0001). The MST of patients with serum CEA decreased ≥32% was similar to those with CEA decreased ≥61% (9.5 months vs 10.5 months,P=0.370), but both longer than those with CEA decreased<32% (6.7 months, P<0.001). Cox multivariate survival analysis confirmed that serum CEA level decreased ≥32%, CEA level decreased ≥61%, PS score, and DC are independent prognostic factor, but not OR. Conclusions To advanced NSCLC patients, the disease control rate (DCR) may be more suitable than objective response rate (ORR) as an indicator in predicting the efficacy and prognosis in advanced NSCLC patients. Serum CEA levels decreased ≥32% may be a reliable indicator to determine the therapeutic efficacy of EGFR-TKIs.  相似文献

表皮生长因子受体酪氨酸激酶抑制剂( EGFR-TKI)在非小细胞肺癌的治疗中具有重要地位,但有研究发现患者会对EGFR-TKI产生原发性耐药或获得性耐药。目前发现获得性耐药的多种机制最终都导致表皮生长因子受体的下游信号通路被重新激活。肝X受体激动剂对表皮生长因子受体最重要的下游通路PI3K-Akt-NF-κB的多个主要环节均有不同程度的抑制作用,有望逆转EGFR-TKI的继发耐药。  相似文献

摘 要:表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI )至今已上市近二十年。第一代EGFR-TKI在提高EGFR突变晚期非小细胞肺癌(NSCLC)的客观缓解率(ORR)、延长无进展生存期(PFS)方面起了重大的贡献。第二代EGFR-TKI在延长总生存期(OS)方面带来了惊喜。第三代EGFR-TKI克服了第一二代药物的耐药,其一线PFS可能打破现有治疗的格局。第四代EGFR-TKI已在研发中且EGFR-TKI研究已扩展到术后辅助治疗领域,期待其进一步的发展。  相似文献

随着肺癌分子生物学研究的不断深入,小分子靶点类抗肿瘤药物取得了突破性的进展,表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)是其中最受人关注的.多项研究证实了EGFR-TKI具有放射增敏性.放疗单独联合EGFR-TKI可使身体状况差的患者生存获益,但仍不能忽视肺毒性.然而,EGFR-TKI与放化疗联合能否使局部晚期NSCLC患者获益仍存在较大争议.  相似文献

Objective: Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR)-activating mutations have higher response rate and more prolonged survival following treatment with single-agent EGFR tyrosine kinase inhibitor (EGFR-TKI) compared with patients with wild-type EGFR. However, all patients treated with reversible inhibitors develop acquired resistance over time. The mechanisms of resistance are complicated. The lack of established therapeutic options for patients after a failed EGFR-TKI treatment poses a great challenge to physicians in managing this group of lung cancer patients. This study evaluates the influence of EGFR-TKI retreatment following chemotherapy after failure of initial EGFR-TKI within at least 6 months on NSCLC patients. Methods: 'i-he data of 27 patients who experienced treatment failure from their initial use of EGFR-TKI within at least 6 months were analyzed. After chemotherapy, the patients were retreated with EGFR-TKI (gefitinib 250 mg qd or erlotinib 150 mg qd), and the tumor progression was observed. The patients were assessed for adverse events and response to therapy. Targeted tumor lesions were assessed with CT scan. Results: Of the 27 patients who received EGFR-TKI retreatment~ 1 (3.7%) patient was observed in complete response (CR), 8 (29.6%) patients in partial response (PR), 14 (51.9%) patients in stable disease (SD), and 4 (14.8%) patients in progressive disease (PD). The disease control rate (DCR) was 85.2% (95% CI: 62%-94%). The median progression-free survival (mPFS) was 6 months (95% CI: 1-29). Of the 13 patients who received the same EGFR-TKI, 1 patient in CR, 3 patients in PR, 8 patients in SD, and 2 patients in PD were observed. The DCRwas 84.6%, and the mPFS was 5 months. Of the 14 patients who received another EGFR-TKI, no patient in CR~ 6 patients in PR, 6 patients in SD, and 2 patients in PD were observed. The DCRwas 85.7%, and the mPFS was 9.5 months.

EGFR作为NSCLC靶向治疗的热点,近年来其在分子生物学水平的研究众多。而放疗作为一种NSCLC重要的传统治疗方法,其疗效与EGFR突变及过表达相关。放疗联合EGFR-TKI在NSCLC治疗上的疗效还缺乏Ⅲ期临床结果。miRNAs能够调控肿瘤相关基因表达,影响肿瘤生物学活动。近来研究显示miRNAs对EGFR突变、EGFR-TKI和放疗均存在正向或负向的调控作用,其具体机制已部分阐明。现就miRNAs对EGFR突变、EGFR-TKI及放疗间相关性作一综述,旨在为miRNAs应用于放疗联合EGFR-TKI治疗NSCLC提供最新诊疗依据。  相似文献
