| 目的：观察贝伐珠单抗联合化疗对晚期非小细胞肺癌患者的疗效、安全性及影像学改变。方法：对2007 年至2014 年于我院
治疗的晚期NSNSCLC（非鳞非小细胞肺癌non-squamous non-small cell lung cancer) 患者，给予贝伐珠单抗（15 mg/kg 或7.5
mg/kg）联合化疗（紫杉醇175 mg/m2，d1，卡铂AUC=5 或6，d1，q3 w）6周期及贝伐珠单抗维持治疗（15 mg/kg 或7.5 mg/kg，d1，q3
w）。观察疗效、不良反应、肺部病灶空洞改变的情况、恶性胸腔积液的治疗效果及部分患者EGFR、KRAS 基因突变状况。结果：共
观察26 例患者，均接受贝伐珠单抗联合化疗，17 例行贝伐珠单抗维持治疗。部分缓解（partial response, PR）、疾病稳定（stable disease,
SD）、疾病进展（disease progression, PD）率分别为53.8 %、42.3 %、3.8 %。中位无进展生存期（progression free survival, PFS）为
11.0 个月，中位总生存期（overall survival, OS）达25.8 个月。26例患者中15.4 %治疗后病变发生空洞改变，空洞组的2 年、3 年生
存率略高于无空洞组，但无统计学差异（P值分别为0.586、0.509）。13 例患者伴有恶性胸腔积液，胸腔积液的疾病控制率为100
%。11 例患者标本可进行EGFR 基因检测，敏感突变占36.4 %，未突变占63.6 %。对10 例患者标本行KRAS基因检测，均为突变
阴性。不良反应包括骨髓抑制、消化道反应、鼻衄、咯血、高血压、蛋白尿等。大多数不良反应程度较轻，可控制。结论：贝伐珠单抗
联合化疗治疗晚期NSNSCLC 患者疗效确切，副反应可耐受，控制恶性胸腔积液效果较好。肺部病灶空洞改变的临床意义有待进
一步研究。 |

| Objective:To evaluate the efficacy, safety and imaging findings of bevacizumab plus chemotherapy in patients with
advanced non-squamous non-small cell lung cancer (NSNSCLC).Methods:Patients admitted in the hospital from 2007 to 2014 were
treated with bevacizumab (15 mg/kg or 7.5 mg/kg, d1) plus chemotherapy(paclitaxel 175 mg/m2, d1, carboplatin AUC=5 or 6, d1) with 3
weeks in one cycle, up to 6 cycles, followed with maintenance therapy of bevacizumab (15 mg/kg or 7.5 mg/kg, d1) till disease
progression. Efficacy, safety, tumoral cavitation, therapeutic outcome of malignant pleural effusion and EGFR, KRAS mutation status
were analyzed.Results:26 Patients were collected. They were all treated with bevacizumab plus chemotherapy. 17 patients received
maintenance therapy. Partial response (PR), stable disease (SD) and progressive disease (PD) rates were 53.8 %, 42.3 % and 3.8 %,
respectively. The median progression free survival(PFS) and overall survival(OS) were11.0 months and 25.8 months respectively. Out of
26 patients, 15.4 % developed cavitation after treatment. 2 years and 3 years survival rate of cavitation group was slightly higher than
those of non-cavitation group (75.0 %vs 44.4 %, P=0.586, 25.0 %vs 12.5 %, P=0.509, respectively). Of the 13 patients with malignant
pleural effusion, the disease control rate of malignant pleural effusion was 100 %. EGFR mutation was detected in 11 patients. 36.4 %
patients showed mutation positive while 63.6 % showed mutation negative. KRAS mutation had not been found in all the 10 patients
whose samples were detected. Adverse effects included myelosuppression, digestive symptoms, epistaxis, hemoptysis, hypertension,
proteinuria, etc. Most of the adverse effects were mild and controllable.Conclusion:Bevacizumab combined with chemotherapy is a
promising and safe treatment for patients with NSNSCLC. It was also effective in controlling malignant pleural effusion. The clinical significance of tumoral cavitation is subject to further research. |
