作者报告1960—1973年收治的供分析的恶性涎腺肿瘤40例。共分三组。第一组对大块肿瘤进行照射19例,其中12例为术后肿瘤肉眼复发,7例为不能手术的肿瘤,放疗为惟一肯定的治疗手段。第二组对镜下有残余病灶病例进行照射者共17例,14例或是镜下有残余病灶,或是基于手术范围或病理特点估计其有很大复发危险者。第三组4例全部接受了相对低剂量的术前照射。40例的原发部位:27例在耳下腺;7例在颌下腺;6例在舌下涎腺。放射治疗技术,用~(60)钴、6MeV直线加速器的γ线或15—20MeV β线治疗。治疗体积依临
The authors report 40 cases of malignant salivary gland tumors analyzed from 1960 to 1973. There are three groups. In the first group, 19 cases of large tumors were irradiated, of which 12 cases were macroscopic recurrences of postoperative tumors and 7 cases were inoperable tumors. Radiotherapy was the only positive treatment. The second group had a total of 17 cases with residual lesions under the microscope. There were 14 cases with residual lesions under the microscope or those whose risk of recurrence was estimated based on the range of operation or pathology. The third group of 4 patients all received a relatively low dose of preoperative irradiation. In 40 cases, the primary site was 27 cases in the subarachnoid gland; 7 cases in the submandibular gland; and 6 cases in the sublingual parotid gland. Radiotherapy techniques were treated with ~(60) cobalt, 6MeV linac gamma rays or 15-20 MeV beta rays. The volume of treatment depends on
