老年人非霍奇金淋巴瘤头颈部放疗口腔感染发生相关因素分析

Factors of oral infection in elderly patients with head and neck radiotherapy for malignant lymphoma

目的 探讨老年人恶性淋巴瘤头颈部放疗口腔感染发生的相关因素,为临床防治提供依据. 方法 选取2007年3月至2012年3月期间收治的97例老年恶性淋巴瘤头颈部放疗患者病历资料做研究对象.分析老年恶性淋巴瘤头颈部放疗与发生口腔感染的相关因素. 结果 共25例发生口腔感染,口腔感染发生率25.77％；通过单因素分析,文化程度、职业、病期、口腔自洁、口腔环境、是否化疗是患者发生口腔感染的相关重要因素（x2=8.634、6.863、9.237、11.870、7.563、8.012,均P＜0.01）,性别比较口腔感染的发生率差异无统计学意义. 结论 老年恶性淋巴瘤头颈部放疗患者口腔感染的发生与多种因素有关,其中口腔自洁习惯差、齿龈病变史、化疗是导致放疗后口腔感染发生的重要危险因素.

Objective To investigate the factors relating to oral infection in elderly patients treated with head and neck radiotherapy for malignant lymphoma and to provide the clinical basis for the prevention and treatment of oral infections.Methods A total of 97 patients treated with head and neck radiotherapy for malignant lymphoma from March 2007 to March 2012 were enrolled.The factors relating to oral infection after head and neck radiation therapy were analyzed.Results Totally 25 patients （25.77%,25/97） had oral infections.The single-factor analysis showed that education degree,occupation,cancer staging,oral self-cleaning,oral environment,chemotherapy were the important factors relating to oral infection （x2 =8.634,6.863,9.237,11.870,7.563,8.012,P〈0.01）.The incidence of oral infection had no significant differences between male and female patients.Conclusions There are many factors relating to oral infection in elderly patients treated with head and neck radiotherapy for malignant lymphoma,and poor oral self-cleaning,history of gum disease and chemotherapy are the important related factors.
