头颈部癌最常见的失败原因是局部复发。手术虽对有些病人有效,但常因病变的部位或范围而不能施行,尤其是复发性病变位于鼻咽及口咽部者更难以手术。许多权威反对再照射,因为有发生并发症的高度危险。但最近有些临床及实验结果证明头颈部癌复发的再照射是比较安全可行的,本文准备对此种治疗的临床价值进行评价。 The most common cause of head and neck cancer failure is local recurrence. Although surgery is effective for some patients, it is often not performed due to the location or extent of the lesion. Especially, recurrent lesions in the nasopharyngeal and oropharyngeal are more difficult to operate. Many authorities oppose re-irradiation because of the high risk of complications. However, some clinical and experimental results have recently proved that re-irradiation of head and neck cancer recurrence is relatively safe and feasible. This article is prepared to evaluate the clinical value of this treatment.
