Merkel细胞癌为皮肤神经内分泌肿瘤。有关该瘤放疗的报道甚少。作者1980～1990年间共收治11例(均经病理诊断)。其中术后放疗8例,单纯放疗3例,前者术后均无大体残瘤,后者均有区域淋巴结转移。放疗剂量:深部X线,30Gy/15次/18天～50Gy/15次/20天;高能X线或电子束,32.4Gy/18次/22天～60Gy/30次/43天。随访6～64个月时,术后放疗照射瘤床和淋巴引流区的6例都获
Merkel cell carcinoma is a neuroendocrine tumor of the skin. There have been very few reports of this tumor radiotherapy. The authors treated a total of 11 cases (all diagnosed by pathology) between 1980 and 1990. Among them, there were 8 cases of postoperative radiotherapy and 3 cases of radiotherapy alone. The former had no gross residual tumor after surgery, and the latter had regional lymph node metastasis. Radiotherapy dose: deep X-ray, 30 Gy/15 times/18 days to 50 Gy/15 times/20 days; high-energy X-ray or electron beam, 32.4 Gy/18 times/22 days to 60 Gy/30 times/43 days. During the follow-up of 6 to 64 months, 6 cases of postoperative radiotherapy irradiation on the tumor bed and lymphatic drainage were obtained.
