Br J Cancer:根治性放疗后头颈癌患者的血行感染分析

2021-05-31 xiaozeng MedSci原创

既往研究显示,

既往研究显示,头颈部鳞状细胞癌(HNSCC)的根治性放疗或放化疗(RT/CRT)与大量毒性相关,基于人群的研究报告显示,90天和180天的死亡率分别为3-4%和7–10%。患者在接受治疗后可能会出现免疫功能低下,相当大比例的RT/CRT早期死亡是由非癌症的原因引起的,因此在某些情况下可能是可以预防的。

在该项基于人群的研究中,研究人员旨在研究RT/CRT后血行感染(BSI)的早期危险因素、微生物病因、预后及其对早期非癌症死亡率的影响。

研究人员通过分析国家注册机构中的数据,确定了2010年至2017年期间在丹麦接受治愈性RT/CRT治疗的咽、喉和口腔HNSCC患者,以及在RT/CRT治疗后18个月内BSI的发生情况。

相关研究流程图

研究人员共纳入了5674名患者信息,观察到了238个BSI事件。年龄的增长、疾病阶段和体力状态均与BSI的风险显著相关,而性别、吸烟和高级别粘膜炎则无相关性。

相关累积发病率曲线

人乳头瘤病毒阳性(HPV+)口咽癌患者的风险降低。金黄色葡萄球菌感染占前3个月BSI发作的34%。BSI发生后30天的死亡率为26%,而BSI也是10%的早期非癌症死亡原因。


总而言之,该研究结果表明,BSI的发生风险与几种与患者和疾病相关的因素相关,BSI会显著提高患者的早期非癌症死亡率。且对该人群进行可疑的全身感染治疗时,抗生素治疗方案应优先覆盖金黄色葡萄球菌。
