Effect of inducing chemotherapy + chrono-chemotherapy + intensity-modulated radiation therapy on the survival and tumor malignancy in patients with nasopharyngeal carcinoma

摘要

Objective:To analyze the effect of inducing chemotherapy + chrono-chemotherapy + intensity-modulated radiation therapy on the survival and tumor malignancy in patients with nasopharyngeal carcinoma.Methods: A total of 60 patients with locally advanced nasopharyngeal carcinoma were divided into observation group and control group according to different treatment, observation group received inducing chemotherapy + chrono-chemotherapy + intensity-modulated radiation therapy and control group received conventional treatment. Differences in the survival and tumor malignancy were compared between two groups.Results:miR-143 and miR-218 expression levels in nasopharyngeal carcinoma tissue of observation group after treatment were higher than those of control group, and miR-7 expression level was lower than that of control group; caspase-3, GRP-78 and Bax protein expression levels in tumor tissue of observation group after treatment were higher than those of control group, and Bcl-2 protein expression level was lower than that of control group;serum VEGF, -HBDH, CYFRA21-1 and PCⅢ levels of observation group after treatment were lower than those of control group.Conclusion:Inducing chemotherapy + chrono-chemotherapy + intensity-modulated radiation therapy can reduce the tumor malignancy and optimize the quality of life in patients with nasopharyngeal carcinoma.
