Bevacizumab Concomitant with Chemotherapy is Effective in Treating Chinese Patients with Advanced Non-Squamous Non-Small Cell Lung Cancer

Objectives: To retrospectively review the safety and clinical efficacy of bevacizumab concomitant withchemotherapy in Chinese patients with advanced non-squamous non-small cell lung cancer (NSNSCLC). Methods:Clinical data for 79 patients with NSNSCLC who received bevacizumab concomitant with chemotherapy inChinese PLA General Hospital from April 28th 2009 to May 5th 2013 were retrospectively reviewed to analyzethe clinical efficacy including disease control rate (DCR), overall response rate (ORR), progression-free survival(PFS), overall survival (OS), the Eastern Cooperative Oncology Group (ECOG) score and the safety. Results:The Eastern Cooperative Oncology Group (ECOG) score was 0-2. By the final cutoff date (June 9, 2013), 54(68.4%) patients had disease progression and 37 (46.8%) died. The ORR was 32.9% and the DCR was 83.5%.The ORR of the first-, second-, and third- or later-line treatments were 51.4%, 25.0% and 12.5%, while the DCRwere 94.3%, 80.0% and 70.8%, respectively. The median OS (mOS) and PFS (mPFS) were 13.5 and 5.83 months,respectively. The mOS of patients with the first-, second-, and third- or later- line treatments were 16.2, 10.9and8.30 months, while the mPFS were 7.27, 5.90 and 5.17 months, respectively. Chemotherapy-related adverseevents included myelosuppression, vomiting, hepatic dysfunction and renal dysfunction, while the commonserious bevacizumab-related adverse events were thromboembolic problems, gastrointestinal perforation andreversible posterior leukoencephalopathy syndrome, which could be well managed. Conclusions: Bevacizumabconcomitant with chemotherapy is effective and the related toxicity can be well tolerated in Chinese patientswith NSNSCLC.

Objective: To investigate the effect of coenzyme complex on decreasing cardiotoxicity in elderly patients withgastrointestinal cancer who were treated by chemotherapy. Methods: From September 2011 to February 2015,we recruited 54 elderly (with more than 70 years of age) patients with gastrointestinal cancer, with advanceddisease. Then treated with chemotherapy combined with or without coenzyme complex. After two cycles oftreatment, the effect of coenzyme complex on decreasing cardiotoxicity were evaluated. Results: Chemotherapywas combined with coenzyme complex in 32 patients (22man, 10 woman; median age: 74 years, range: 70-87years) without coenzyme complex in 22 patients (15man, 7 woman; median age: 73 years, range: 70-80 years) withgastrointestinal cancer. Cardiac event was significantly lower in patients treated with chemotherapy combinedwith coenzyme complex (p<0.01). Conclusions: Coenzyme Complex decreased cardiotoxicity when combinedwith chemotherapy in treating elderly patients with gastrointestinal cancer.

The median age of patients was 59 (40-82) years. Incidences of Grade 1 to 2 myelosuppression was observed in 5/34 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 3/34 patients. Adverse effects on the gastrointestinal tract were documented in 5/34 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Conclusions: Liena polypeptide injection combined with chemotherapy was safe in treating several sites of tumors, that mainly included lung, colorectal and breast cancer. However, further study should be conducted to clarify the effectiveness of this treatment.

Bevacizumab in Combination with Metronomic Chemotherapy in Patients with Anthracycline- and Taxane-Refractory Breast Cancer

Abstract

A vascular endothelial growth factor (VEGF) inhibitor might enhance metronomic chemotherapy in previously treated metastatic breast cancer (MBC) patients. Anthra-cycline and taxane refractory MBC patients were given cyclophosphamide 50 mg p.o. daily, methotrexate 1 mg/kg i.v. every 14 days, and bevacizumab 10 mg/kg i.v. every 14 days. Trastuzumab was added in HER2-overexpressing tumors. 24 patients were enrolled and 22 were evaluable. All tumors had histologic grade II-III and most patients had ≥2 metastatic sites. After a median follow-up of 7.7 months the response rates were: complete response (CR) 0%, partial response (PR) 31.8% (95% CI 13.9-54.9%), stable disease for ≥24 weeks (SD) 31.8% (95% CI 13.9-54.9%). Clinical benefit (CB= CR + PR + SD>24w) 63.6% (95% CI 40.7-82.8%). Median progression-free survival (PFS) was 7.5 months; overall survival (OS) was 13.6 months. HER2-overex-pressing or high proliferative-index tumors had better 6-month PFS (75% vs. 34% in HER-negative tumors P= 0.043; 67% vs. 0% in Ki-67 ≥20% tumors, P = 0.015). Adverse effects were mild. The combination of bevacizumab and a metronomic-based chemotherapy was effective, well tolerated and provided clinical benefit in heavily-treated MBC patients.

Efficacy and Safety of Bevacizumab in Chinese Patients with Metastatic Colorectal Cancer

Objective: To evaluate the efficacy and safety of bevacizumab in the treatment of patients with metastatic colorectal cancer (mCRC). Methods: In a single-center, observational study of 91 Chinese patients with mCRC who received bevacizumab in combination with chemotherapy was conducted. Objective response rates (ORRs), progression-free survival (PFS), overall survival (OS) and adverse events were recorded, and the relationships between various clinical factors and PFS or OS were evaluated by Cox proportional hazards models. Results: Treatment with bevacizumab and chemotherapy was effective and tolerable. Univariate analysis showed that PFS and OS were significantly associated with the Eastern Cooperative Oncology Group performance status (ECOGPS) score, duration of bevacizumab exposure, and whether chemotherapy was continued after discontinuation of bevacizumab treatment. A multivariate analysis showed that the duration of bevacizumab exposure and whetherchemotherapy was continued after discontinuation of bevacizumab were independent prognostic factors for PFS and OS. Conclusion: In Chinese mCRC population, the shorter the duration of exposure to bevacizumab and chemotherapy, the worse the prognosis is.
