Salvage Therapy of Gemcitabine Plus Endostar SignificantlyImproves Progression-free Survival (PFS) with PlatinumresistantRecurrent Epithelial Ovarian Cancer

Anti-angiogenic agents have played crucial roles in the treatment of ovarian cancer in recent years, butpotential benefits of endostatin have been largely unexplored. The present retrospective study evaluated itsefficacy and toxicity with two cohorts of patients with platinum-resistant recurrent ovarian cancer. One cohortreceived gemcitabine plus endostar (rh-endostatin), and the second cohort received gemcitabine regimen alone,with totals of 31 and 27 patients, respectively. The main endpoints were disease control rate (DCR), PFS, overallsurvival (OS) and safety. There were statistically significant differences in DCR (70.9% vs. 40.7%; P = 0.02) andPFS (6.3 months vs. 3.2 months, P = 0.001) between the two cohorts. Though the endostar cohort also improvedmedian OS by 2.1 months, there was no statistically significant difference compared with gemcitabine alonecohort in this case (12.5 months vs. 10.4 months, P = 0.201). Treatment was well tolerated for most patients, andtoxicity of endostar was negligible. Gemcitabine plus endostar significantly improved the prognosis in patientswith platinum-resistant recurrent ovarian cancer, especially in those with malignant effusion. The endostarcontainingregimen is recommended in this setting.

Efficacy and Safety of Endostar Combined with Chemotherapy in Patients with Advanced Solid Tumors

Purpose: Endostar® is a proteolytic fragment of collagen XVIII that has been shown to have antitumor activity, with a favorable toxicological profile. We conducted this study to investigate its efficacy and safety when combined with chemotherapy in patients with advanced solid tumors. Methods: From July 2006 to September 2008, 45 patients with histologically or cytologically confirmed solid tumors were enrolled into this study. All received Endostar at a dose of 7.5 mg/m2/day as an intravenous infusion for more than 7 days, in combination with chemotherapy. Patients were treated until tumor progression or unacceptable toxicity. Results: No treatment related death occurred in this study. Main reported toxicities included: mylosuppression (82.2%), hepatic impairment (42.2%), anorexia (20.0%), nausea (24.4%), vomiting (22.2%), diarrhea (20.0%), febrile (20.0%) and fatigue (24.4%). No complete response was observed. Two patients (2/42) had partial response, twenty-one (21/42) remained stable, and nineteen (19/42) had progressive disease. Median time to tumor progression was 3.0 months (range, 0.5-12.0). Median overall survival was 30.0 months (95% confidence interval: 20.0-40.0) and 1 year survival rate was 81.0%. Conclusion: Our study revealed that toxicity of Endostar combined with chemotherapy in the treatment of solid tumors was tolerable with moderate efficacy.     

内皮抑素对人肺腺癌A549细胞周期及HIF-1表达的影响

目的研究内皮抑素在体外对人肺腺癌细胞A549的影响及机制。方法流式细胞术（FCM）检测内皮抑素治疗后,肺腺癌细胞A549的细胞周期分布;酶联免疫吸附法（ELISA）检测处理前后细胞中HIF-1的表达情况。结果内皮抑素处理肺腺癌A549细胞,可以使该细胞S期和G₂/M期细胞比例增多,抑制HIF-1的表达,且随处理时间的延长,HIF-1的抑制率不断提高。结论内皮抑素可以使A549细胞阻滞在G2/M期及S期的比例明显增加,从而为其他手段抑制A549细胞的增殖或直接杀伤A549细胞提供了基础;内皮抑素可以抑制肿瘤细胞的HIF-1表达,HIF-1是肿瘤细胞耐受放化疗的因素之一,因此联合内皮抑素治疗有可能提高放、化疗疗效。     

恩度联合化疗治疗晚期非小细胞肺癌的临床研究

目的：观察恩度（重组人血管内皮抑素）联合含铂化疗方案治疗晚期非小细胞肺癌的近期疗效和安全性,并与单纯含铂化疗方案比较。方法：依照入选标准,选择60例晚期NSCLC住院患者,分恩度联合化疗组28例和单纯化疗组32例,观察有效率（RR）、疾病控制率（DCR）、生活质量改善情况及不良反应。结果：恩度联合化疗组和单纯化疗组的有效率分别为28.57%和28.13%,无统计学差异（P〉0.05）;疾病控制率分别为96.43%和93.75%,无统计学差异（P〉0.05）。治疗后两组ECOG评分均较治疗前明显降低,具有统计学差异（P〈0.05）,但两组间比较,无统计学差异（P〉0.05）。恩度联合化疗组的临床症状缓解率较单纯化疗组高：咳嗽缓解率分别为80%和71.43%、气短缓解率分别为78.57%和75%、咯血缓解率分别为90%和81.82%、疼痛缓解率分别为75%和71.43%,但无统计学差异（P〉0.05）。两组的主要不良反应均为恶心/呕吐、疲乏及骨髓抑制,骨髓抑制以白细胞、中性粒细胞减少为主,患者均可耐受,两组间不良反应发生率均无统计学差异（P〉0.05）。结论：恩度与含铂化疗联合应用,未改善近期疗效,未增加不良反应,但具有提高生活质量的趋势,值得临床进一步研究。
