目的分析讨论贝伐珠单抗注射液联合盐酸埃克替尼片治疗中晚期非小细胞肺癌的临床疗效及安全性。方法选择某院治疗的72例中晚期非小细胞肺癌患者(2017年12月~2018年12月)展开研究,以随机法将患者均分为观察组与参照组,各有36例。参照组接受盐酸埃克替尼片治疗,观察组接受贝伐珠单抗注射液联合盐酸埃克替尼片治疗。结果观察组总缓解率高于参照组(P<0.05);两组患者治疗前的血清肿瘤标志物水平比较无统计学意义;经治疗,观察组VEGF(血管内皮生长因子)、CA125(糖类抗原125)以及CYFRA21-1(细胞角质白19片段)等血清肿瘤标志物水平均低于对照组(P<0.05);观察组血小板减少、白细胞降低、蛋白尿、胃肠道反应等毒副反应发生率均低于参照组(P<0.05)。结论对中晚期非小细胞肺癌采取贝伐珠单抗注射液联合盐酸埃克替尼片治疗,可有效降低血清肿瘤标志物水平以及毒副反应,疗效显著。  相似文献

IntroductionWhether patients with resectable colorectal liver metastases (CRLM) gain a survival benefit from perioperative chemotherapy remains controversial. The benefit of including bevacizumab in chemotherapy also remains unclear.Material and MethodsSeventy-six patients with CRLM were randomly assigned to either 6 cycles of FOLFOX (folinic acid, 5-fluorouracil, and oxaliplatin)/FOLFIRI (folinic acid, 5-fluorouracil, and irinotecan) with bevacizumab before and after surgery or 12 cycles after surgery. Progression-free survival (PFS) was estimated using the Kaplan-Meier method and compared by the log-rank test.ResultsThe median PFS of all patients was 37.4 months at 5.4 years follow-up, and the median overall survival (OS) was not reached. The PFS between the perioperative group and the postoperative group did not reveal a statistical difference (P = .280). The OS was significantly better in the perioperative group (hazard ratio [HR], 0.60; 95% confidence interval [CI],) 0.35-1.02; P = .049). In subgroup patients with carcinoembryonic antigens (CEA) ≥ 5 ng/mL or those with over 2 liver metastases, perioperative group had longer OS than postoperative group (CEA: HR, 0.49; 95% CI, 0.25-0.93; P = .030; number of liver metastases: HR, 0.55; 95% CI, 0.30-0.99; P = .049). The largest liver metastases size, disease-free interval, and sidedness did not affect PFS or OS. There was no difference between the 2 groups in postoperative complications with bevacizumab or adverse events during chemotherapy.ConclusionsIn patients with resectable CRLMs, perioperative chemotherapy had no effect on PFS, but improved OS. Patients with high CEA levels or over 2 liver metastases may benefit from perioperative chemotherapy.  相似文献

目的 评估贝伐珠单抗治疗放射性脑坏死(cerebral radiation necrosis,CRN)的疗效及安全性,为临床合理应用提供指导。方法 回顾性分析既往接受甘露醇及激素治疗失败的或初治的放射性脑坏死患者14例。所有入组患者按治疗方案的不同分为2组(5.0 mg/kg组每14 d重复1次和7.5 mg/kg组每21 d重复1次)。分别比较2组患者头颅MRI T1W1相增强病灶的变化情况及T2W1相病灶水肿情况,记录患者的临床症状、卡氏(KPS)评分改变情况及药物的不良反应。结果 14例患者均完成了至少2个周期的治疗。治疗2个周期后,2组患者KPS评分均较前改善,5.0 mg/kg组KPS评分较治疗前平均提高31.66分,7.5 mg/kg组KPS评分较治疗前平均提高27.50分。分别比较2组患者治疗前后的MRI T1W1相增强病灶的变化情况及T2W1相病灶水肿变化情况均有不同程度改善,其中5.0 mg/kg组CRN病灶体积平均减少(46.0±9.4)%(t=6.57,P<0.05),病灶水肿区体积平均减少(68.9±8.9)%(t=3.32,P<0.05),7.5 mg/kg组CRN病灶体积平均减少(53.9±10.7)%(t=7.89,P<0.05),病灶水肿区体积平均减少(77.1±14.3)%(t=4.22,P<0.05),差异有统计学意义。而2组患者在CRN病灶平均体积及病灶水肿区体积的减小程度上比较差异无统计学意义(P>0.05)。5.0 mg/kg组患者总的治疗过程中与7.5 mg/kg组相比,不良事件发生率差异无统计学意义(P>0.05)。结论 贝伐珠单抗能明显改善放射性脑坏死患者的临床症状并提高生活质量,5.0 mg/kg每14 d重复1次的治疗方案安全性与7.5 mg/kg每21 d重复1次的治疗方案相似,对CRN的治疗有借鉴意义。  相似文献

BackgroundThe use of immune checkpoint inhibitors combined with vascular endothelial growth factor (VEGF)-targeted therapy as second-line treatment for metastatic clear cell renal cancer (mRCC) has not been evaluated prospectively.ObjectiveTo evaluate the efficacy and safety of atezolizumab + bevacizumab following disease progression on atezolizumab or sunitinib monotherapy in patients with mRCC.Design, setting, and participantsIMmotion150 was a multicenter, randomized, open-label, phase 2 study of patients with untreated mRCC. Patients randomized to the atezolizumab or sunitinib arm who had investigator-assessed progression as per RECIST 1.1 could be treated with second-line atezolizumab + bevacizumab.InterventionPatients received atezolizumab 1200 mg intravenously (IV) plus bevacizumab 15 mg/kg IV every 3 wk following disease progression on either atezolizumab or sunitinib monotherapy.Outcome measurements and statistical analysisThe secondary endpoints analyzed during the second-line part of IMmotion150 included objective response rate (ORR), progression-free survival (PFS), and safety. PFS was examined using Kaplan-Meier methods.Results and limitationsFifty-nine patients in the atezolizumab arm and 78 in the sunitinib arm were eligible, and 103 initiated second-line atezolizumab + bevacizumab (atezolizumab arm, n = 44; sunitinib arm, n = 59). ORR (95% confidence interval [CI]) was 27% (19–37%). The median PFS (95% CI) from the start of second line was 8.7 (5.6–13.7) mo. The median event follow-up duration was 19.4 (12.9–21.9) mo among the 25 patients without a PFS event. Eighty-six (83%) patients had treatment-related adverse events; 31 of 103 (30%) had grade 3/4 events. Limitations were the small sample size and selection for progressors.ConclusionsThe atezolizumab + bevacizumab combination had activity and was tolerable in patients with progression on atezolizumab or sunitinib. Further studies are needed to investigate sequencing strategies in mRCC.Patient summaryPatients with advanced kidney cancer whose disease had worsened during treatment with atezolizumab or sunitinib began second-line treatment with atezolizumab + bevacizumab. Tumors shrank in more than one-quarter of patients treated with this combination, and side effects were manageable.  相似文献

AimThe multicentre non-interventional AVANTI study assessed safety, effectiveness and patient-reported outcomes with approved first-line bevacizumab-containing regimens for HER2-negative locally recurrent/metastatic breast cancer (LR/MBC) in German routine oncology practice.MethodsEligible patients had HER2-negative LR/MBC, no bevacizumab contraindications and no prior chemotherapy for LR/MBC. Chemotherapy schedule, diagnostics and follow-up were at physicians’ discretion. Data were collected for 1 year after starting bevacizumab, then every 6 months for 1.5 years (maximum follow-up: 2.5 years). Patients and physicians rated treatment satisfaction. Subgroup analyses were prespecified in clinically relevant populations, including triple-negative breast cancer (TNBC).ResultsBetween November 1, 2009 and April 30, 2016, 2065 eligible patients at 346 centres received bevacizumab with paclitaxel or capecitabine. Patients receiving bevacizumab–capecitabine were less likely to have de novo disease and more likely to have TNBC, age ≥60 years and prior anthracycline/taxane and/or endocrine therapy. Median PFS was 12.6 (95% CI 11.9–13.2) months (12.8 with bevacizumab–paclitaxel, 10.5 with bevacizumab–capecitabine); median OS was 23.9 (95% CI 22.2–25.1) months. Outcomes were worse in patients with TNBC, prior anthracycline/taxane or prior endocrine therapy. Grade ≥3 adverse events occurred in 27% of patients. Treatment was discontinued for adverse events in 15%. Treatment satisfaction was rated as good or better by 304/394 responding patients (77%) at week 54 and in 1393/2065 patients (67%) by physicians overall.ConclusionsIn routine clinical practice, effectiveness and safety of first-line bevacizumab-containing therapy for LR/MBC were consistent with experience from phase III trials. Patient and physician treatment satisfaction showed high concordance.  相似文献
