Effect of bronchial arterial infusion chemotherapy combined with elemene on the malignant lesion molecules and systemic immune response in patients with advanced lung cancer

Objective:To study the effect of bronchial arterial infusion chemotherapy combined with elemene on the malignant lesion molecules and systemic immune response in patients with advanced lung cancer.Methods:A total of 78 patients diagnosed with advanced lung cancer in our hospital between April 2013 and March 2016 were selected as research subjects and randomly divided into observation group who accepted bronchial arterial infusion chemotherapy combined with elemene therapy and control group who accepted bronchial arterial infusion chemotherapy. After 4 weeks of treatment, tumor lesions were collected to determine the expression of proliferation and invasion molecule, and serum was collected to determine the levels of immune cell-related cytokines.Results:After 4 weeks of treatment, TCF3, Livin, Bcl-2, HOXB7, PTTG1, Vimentin, E-cadherin, Rap2a andβ-catenin protein expression in tumor lesions of observation group were significantly lower than those of control group;serum IFN-γ level of observation group was significantly higher than that of control group while IL-4, IL-9, IL-10 and TGF-β levels were significantly lower than those of control group.Conclusions:Bronchial arterial infusion chemotherapy combined with elemene can inhibit the expression of proliferation and invasion of molecules in tumor lesions and improve the systemic anti-tumor immune response in patients with advanced lung cancer.

LONG TERM RESULTS OF BRONCHIAL ARTERIAL INFUSION WITHCHEMOTHERAPEUTIC AGENTS PLUS RADIATION THERAPYIN THE TERATMENT OF LOCALLY ADVANCEDNON SMALL CELL LUNG CANCER

Objective: To evaluate the efficacy of the bronchial arterial infusion (BAI) plus radiation therapy (RT) for locally advanced non-small-cell lung cancer (NSCLC). Methods: 79 patients with locally advanced NSCLC were divided randomly into two groups. In the RT group, the radiation was given by 8Mv X-ray or 18Mv X-ray with 2Gy/fraction, 5 fraction per week with a total dose of 60Gy～65Gy/6～7 weeks. In the BAI+RT group, the radiation was given as RT group. Bronchial arterial infusion was performed before RT. The regimen consisted of DDP 100 mg/m2, MMC 10 mg, and 5-Fu 1000 mg. Each patient received two or three cycles. Results: The overall response rates were 80.5% in BAI+RT group and 50% in RT group. The 1-, 3-, 5-year survival rates in the BAI+RT group were significantly improved when compared to the RT group, being 87.8% vs 36.8%, 39.0% vs 7.9%, and 17.1% vs 2.6% respectively. The median time of radiation treatment to recurrence of primary lesion was 11 months in the BAI+RT group and 5 months in the RT group (P<0.05). The acute reactions were increased but acceptable in BAI+RT group, and the radiation treatments were able to be completed without any break. The late reactions were similar in both groups. Conclusion: The survival rates of patients with locally advanced NSCLC can be improved by BAI+RT without increasing any complication.

The effects on surgery and preoperative patients with non-small cell lung cancer by preoperative bronchial artery infusion chemotherapy

Objective： To study the efficiency, safety and feasibility of preoperative bronchial artery infusion （BAI） chemotherapy on operation in patients with locally advanced （stage Ⅲ） non-small cell lung cancer （NSCLC）. Methods： 92 cases with locally advanced NSCLC patients were randomly divided into two groups： （1） BAI chemotherapy group： 39 cases were received BAI chemotherapy for 2 courses and followed surgery; （2） surgery alone group： 51 cases were treated by operation alone. The complete resection rate and preoperative complications were compared between these two groups. Results： In BAI chemotherapy group, the rate of clinical efficiency was 68.3% with slight toxicity. In BAI chemotherapy group the surgery complete resection rate was 89.7%, which was significantly higher than that in surgery alone group （72.5%, P 〈 0.05）. No significant differences of blood loss, operative complications and mortality were observed between these two groups. Conclusion： BAI neoadjuvant chemotherapy was safe and effective, which can increase the complete resection rate of the tumor and did not increase the operative complications and mortality.

Clinical study of interventional preoperative bronchial artery infusion chemotherapy combined with surgical resection for advanced non-small cell lung cancer

Objective： How to improve the postoperative 5-year survival rate for lung cancer and to give more patients a chance of surgery have become research hotspots. The aim of this research is to evaluate the clinical and pathohistological responses and effects of preoperative bronchial artery infusion （BAI） chemotherapy in patients with locally advanced （stage Ⅲ） non-small cell lung cancer （NSCLC）. Methods： A total of 92 patients with locally advanced NSCLC were randomly divided into two groups. BAI group received BAI chemotherapy for 2 cycles before surgical resection. Surgery group received operation only. The complete resection rate and clinical response were compared between the two groups. Results： In the BAI group, the clinical response rate and the pathohistological response rate were 68.3% and 51.3%, respectively. The complete resection rate in the BAI group was 89.7%, which was significantly higher than that in the surgery group （72.5%） （P 〈 0.05）. The 1- and 2-year survival rate was 100.0% and 80.6% in the BAI group, and 94.1% and 60.0% in the surgery group. Conclusion： BAI neoadjuvant chemotherapy is safe and effective, which has a good clinical and pathohistological response. It might increase the complete resection rate of the tumor and improve the long term survival rate of stage Ⅲ NSCLC patients.

Effect of preoperative bronchial artery infusion chemotherapy on the tumor malignancy of patients with stage IIIA non-small cell lung cancer

Objective:To investigate the effect of preoperative bronchial artery infusion chemotherapy on the tumor malignancy of patients with stage IIIA non-small cell lung cancer.Methods:99 patients with stage IIIA non-small cell lung cancer who underwent surgical treatment in our hospital between January 2015 and August 2018 were chosen as the research subjects, and the preoperative adjuvant therapies were reviewed and used to divide them into the control group (n=51) who received conventional neoadjuvant chemotherapy and the study group (n=48) who received neoadjuvant chemotherapy combined with bronchial artery infusion chemotherapy. The differences in the expression levels of NSCLC-related proliferation, invasion and apoptosis genes in intraoperative lesion tissues were compared between the two groups.Results: NSCLC-related proliferation genes CD137L, dlk1, EZH2 and WT1 mRNA expression in lesion tissues of study group were lower than those of control group whereas DCLAK11 mRNA expression was higher than that of control group;NSCLC-related invasion genes ALX1, periostin and RAC1 mRNA expression were lower than those of control group whereas DAL-1 mRNA expression was higher than that of control group;NSCLC-related apoptosis genes Survivin, Livin, bcl-2 and Bag-1 mRNA expression were lower than those of control group.Conclusion: Preoperative bronchial artery infusion chemotherapy can further inhibit the malignant biological behaviors of cancer cells in patients with stage IIIA NSCLC.

Adenovirus-mediated wild-type p53 gene transfer in combination with bronchial arterial infusion for treatment of advanced non-small-cell lung cancer,one year follow-up

Objective： In the present study, we have examined the safety and efficacy of recombinant adenovirus encoding human p53 tumor suppressor gene （rAd-p53） injection in patients with advanced non-small-cell lung cancer （NSCLC） in the combination with the therapy of bronchial arterial infusion （BAI）. Methods： A total of 58 patients with advanced NSCLC were enrolled in a non-randomized, two-armed clinical trial. Of which, 19 received a combination treatment of BAI and rAd-p53 （the combo group）, while the remaining 39 were treated with only BAI （the control group）. Patients were followed up for 12 months, with safety and local response evaluated by the National Cancer lnstitute＇s Common Toxicity Criteria and response evaluation criteria in solid tumor （RECIST）, respectively. Time to progression （TTP） and survival rates were also analyzed by Kaplan-Meier method. Results In the combo group, 19 patients received a total of 49 injections ofrAd-p53 and 46 times of BAI, respectively, while 39 patients in the control group received a total of 113 times of BAI. The combination treatment was found to have less adverse events such as anorexia, nausea and emesis, pain, and leucopenia （P〈0.05） but more arthralgia, fever, influenza-like symptom, and myalgia （P〈0.05）, compared with the control group. The overall response rates （complete response （CR）＋partial response （PR）） were 47.3% and 38.4% for the combo group and the control group, respectively （P〉0.05）. Patients in the combo group had a longer TTP than those in the control group （a median 7.75 vs 5.5 months, P-0.018）. However, the combination treatment did not lead to better survival, with survival rates at 3, 6, and 12 months in the combo group being 94.74%, 89.47%, and 52.63%, respectively, com- pared with 92.31%, 69.23%, and 38.83% in the control group （P=0.224）. Conclusion： Our results show that the combination of rAd-p53 and BAI was well tolerated in patients with NSCLC and may have improved the quality of life and delayed the disease progression. A further study to better determine the efficacy of this combination therapy is warranted.
