A staging system is suggested for carcinomas of the external and middle ear, based on a personal series of 47 patients. Statistical analysis showed that the proposed system was a valid method of identifying significant predictor factors. Other significant predictors of survival were histology, lymph node metastases, and the patients' general condition. Stage-for-stage there was no significant difference in survival between tumours of the external and middle ear.
基于对47例患者的个人病例系列，提出了一种外耳和中耳癌的分期系统。统计分析表明，所提出的系统是识别重要预测因素的有效方法。其他重要的生存预测因素包括组织学、淋巴结转移和患者的一般状况。在外耳和中耳肿瘤之间，逐期生存率没有显著差异。
