Abstract:
Objective To investigate the clinical effects of radical intensity-modulated radiotherapy (IMRT) combined with concurrent chemotherapy in the treatment of metastatic nasopharyngeal carcinoma. Methods Ninety patients with metastatic nasopharyngeal carcinoma in the First Affiliated Hospital of Hainan Medical University from August 2010 to April 2015 were selected as the research objects. All the patients were randomly divided into the observation group (45 cases) and the control group (45 cases) according to the random lottery envelope. The control group was treated with conventional chemotherapy treatment, and the observation group was treated with radical IMRT based on the treatment of the control group. The efficacy of the patients in both groups was evaluated after the treatment for 4 periods. Results The effective rate in the observation group was higher than that in the control group [66.7 % (30/45) vs. 33.3 % (15/45); χ2= 4.552, P＜ 0.05]. In the observation group, there were 3 cases of radiation esophageal injury and 3 cases of lung injury, and the incidence rate was 13.3 % (6/45), bringing the better treatment outcome. The incidence of side effects such as hair loss, nausea and vomiting, liver and kidney damage, bone marrow suppression in the observation group was 71.1 % (32/45), which was higher than that in the control group [66.7 % (30/45)] and there was no significant difference (χ 2= 0.331, P＞ 0.05). All the patients were followed up. 1 yeas and 2 year survival rates in the observation group were 95.6 % (43/45) and 86.7 % (39/45) respectively, while the control group were respectively 75.6 % (34/45) and 64.4 % (29/45) (χ2values were 6.393 and 5.309, both P＜0.05). Conclusion Radical IMRT combined with concurrent chemotherapy for metastatic nasopharyngeal carcinoma can improve the therapeutic effect and show good safety, and the radiation damage would not affect the treatment process.
