过去认为恶性黑色素瘤对放射治疗不敏感,然而近年来有些作者提出,放射治疗对复发和播散的患者有缓解症状的作用。据报道某患者放射治疗后存活7～10年;另有一扁桃体恶性黑色素瘤患者放射治疗后11年无复发。作者报告1967～1978年经放射治疗的头颈部恶性黑色素瘤31例。男25例,女6例。年龄14～94岁,平均年龄为54岁。从诊断到放射治疗平均为12月,从其他治疗到放射治疗平均为11月。放射治疗前有2例行姑息性肿瘤切除术,26例行广泛肿瘤切除术(伴或不伴颈淋巴结清扫术)。1例仅行颈淋巴结清扫术,2例单用放射治疗的患
In the past, malignant melanoma was considered to be insensitive to radiation therapy. However, in recent years, some authors have suggested that radiation therapy can relieve symptoms in patients with relapse and dissemination. It was reported that a patient survived for 7 to 10 years after radiotherapy; another patient with tonsil malignant melanoma had no recurrence 11 years after radiation therapy. The authors reported 31 cases of malignant melanoma of the head and neck treated with radiation from 1967 to 1978. There were 25 males and 6 females. Age from 14 to 94, with an average age of 54. The average time from diagnosis to radiotherapy is 12 months, and the average from other treatments to radiotherapy is 11 months. Two patients underwent palliative tumor resection before radiotherapy, and 26 patients underwent extensive tumor resection (with or without cervical lymph node dissection). One case was treated with cervical lymph node dissection only, and 2 cases were treated with radiation alone.
