Objective:To study the efficacy and safety of bronchial artery perfusion chemotherapy combined with high-frequency hyperthermia for advanced non-small cell lung cancer. Methods:Patients with advanced non-small cell lung cancer who were treated in Navy General Hospital between May 2014 and October 2016 were selected and randomly divided into two groups, the observation group received bronchial arterial infusion chemotherapy combined with high-frequency hyperthermia, and the control group received bronchial arterial infusion chemotherapy. Before and after treatment, the expression of tumor activity indexes and liver and kidney function indexes in serum as well as and proliferation and invasion genes in tumor lesions were detected respectively.Results: 5 d and 7 d after treatment, serum CEA, MIF, CYFRA21-1 and HE4 levels of both groups of patients were significantly lower than those before treatment and serum CEA, MIF, CYFRA21-1 and HE4 levels of observation group were significantly lower than those of control group;7 d after treatment, MEF2D, c-myc, Survivin, Bcl-2, Vimentin, N-cadherin and Slug expression in tumor lesions of both groups of patients were significantly lower than those before treatment and MEF2D, c-myc, Survivin, Bcl-2, Vimentin, N-cadherin and Slug expression in tumor lesions of observation group were significantly lower than those of control group;serum Scr, BUN, ALT and AST levels were not significantly different between two groups of patients before and after treatment. Conclusion:Bronchial artery perfusion chemotherapy combined with high-frequency hyperthermia for advanced non-small cell lung cancer can significantly inhibit the tumor proliferation and invasion and is with ideal safety.
Objective:To study the effect of percutaneous radiofrequency ablation combined with GP chemotherapy on serum malignant molecule levels in patients withⅢb-Ⅳ stage non-small cell lung cancer.Methods: 110 patients withⅢb-Ⅳ stage non-small cell lung cancer who were treated in Navy General Hospital between July 2013 and August 2016 were collected and divided into the control group (n=58) who received conventional GP chemotherapy and the observation group (n=52) who received percutaneous radiofrequency ablation combined with GP chemotherapy after the therapies were reviewed. Serum levels of tumor markers, angiogenesis indexes and adhesion molecules before and after treatment were compared between two groups of patients.Results: Before treatment, the differences in serum levels of tumor markers, angiogenesis indexes and adhesion molecules were not statistically significant between two groups of patients. After treatment, serum levels of tumor markers Cyfra21-1, ProGRP, SCC-Ag and CA125 in observation group were lower than those in control group;serum levels of angiogenesis indexes IGF-1, bFGF, EGFR and TF were lower than those in control group;serum levels of adhesion molecules sICAM-1 and sVCAM-1 were lower than those in control group.Conclusion: Percutaneous radiofrequency ablation combined with GP chemotherapy can more effectively reduce the malignant degree ofⅢb-Ⅳ stage non-small cell lung cancer.
