局部复发导致头颈肿瘤治疗失败远较远处转移为多。对于最初采用单纯手术治疗后局部复发的头颈癌,再次手术较难,不能手术者需行放疗。本文报告采用放疗治疗20例术后复发的头颈癌的结果。20例肿瘤复发皆经病理证实。其中,男14例,女6例,年龄为34～85岁。口腔癌8例,口咽癌3例,唾液腺肿瘤3例,喉声门上癌6例。囊腺癌3例,其余皆为鳞状细胞癌。单纯放疗13例,手术加放疗7例。采用钴~(30)或6MV线性加速器治疗,每周5天,每次200cGy,总量为4600～7000cGy。随访时间最短2月,最长60月,平均12.8月。2年存活率为25％(5/20),5年存活率为5％
Local recurrence causes head and neck cancer treatment failures to shift far more distantly. For head and neck cancers that have undergone local recurrence after surgery alone, it is difficult to perform surgery again. Those who cannot undergo surgery require radiotherapy. This article reports the results of radiotherapy for 20 cases of recurrent head and neck cancer. 20 cases of tumor recurrence were confirmed by pathology. Among them, there were 14 males and 6 females, aged 34-85 years. There were 8 cases of oral cancer, 3 cases of oropharyngeal cancer, 3 cases of salivary gland tumor, and 6 cases of supraglottic carcinoma. There were 3 cases of cystadenocarcinoma and the rest were squamous cell carcinoma. Radiotherapy alone was used in 13 cases, and surgery plus radiotherapy in 7 cases. Treated with Cobalt~(30) or 6MV linear accelerator, 200 cGy for 5 days per week, totaling 4600 ~ 7000 cGy. The shortest follow-up period was 2 months and the longest was 60 months with an average of 12.8 months. The 2-year survival rate is 25% (5/20), and the 5-year survival rate is 5%
