Abstract
目的分析鼻咽癌全身骨扫描肋骨99mTc-MDP高摄取灶与肋骨转移率及各临床因素之间的关系，筛选肋骨高摄取灶的骨转移危险因素。 方法对312例全身骨扫描出现肋骨99mTc-MDP高摄取灶的鼻咽癌患者进行回顾性分析。采用卡方检验和Logistic回归分析临床因素与肋骨转移的关系。 结果 312例鼻咽癌患者中，肋骨高摄取灶骨转移率在T分期、颅底骨侵犯、其他骨转移、摄取灶数量、双侧肋骨分布范围、是否合并肺外摄取灶上均存在显著差异（均P 结论鼻咽癌肋骨99mTc-MDP高摄取灶的骨转移危险因素包括颅底骨侵犯、其他骨转移、双侧肋骨分布范围、是否合并肺外摄取灶、摄取水平、前后位置。单侧肋骨的单纯性高摄取灶，以随访为主；而双侧肋骨的多发高摄取灶或单发肋骨高摄取灶合并其他骨摄取灶时，需进一步断层影像检查以排除骨转移。
