经典型Kaposi肉瘤的放疗转归过程及近期疗效

目的 探讨经典型Kaposi肉瘤（KS）的放疗转归过程及近期疗效，以期提高对该病的认识及治疗水平。方法 回顾性分析经病理证实的51例经典型KS患者资料，总结其分布特点、放疗转归及近期疗效。结果 经典型KS的发病部位多位于肢体远端，上下肢均受累22例（43.1％），下肢受累16例（31.4％），上肢受累13例（25.5％），在放疗过程中KS的转归分为5个阶段：色素沉着期、局部肿胀期、溃烂渗出期、结痂期和愈合期。放疗的近期有效率为96.1％。结论 放疗是治疗KS的一种有效局部手段，但其转归过程不同于皮肤癌，有较独特的演变过程。

Transfer process and the short-term effect of radiotherapy in classic Kaposi's sarcoma

Objective To explore the transfer process and the short-term of radiotherapy in classic Kaposi＇s sarcoma. Meth- ods In a retrospective analysis of 51 cases with classic Kaposi＇s sarcoma confirmed by pathology, the distribution characteristics of tumor, radiation treatment outcomes and the short-term curative effect were investigated. Results Classic Kaposi＇s sarcoma of Xinjiang province was located in the distal limb. There were 22 （43. 1% ） patients with both upper-and lower-extremity lesions, 16 （31.4%） patients with lower-extremity lesions and 13 （25.5 % ） patients with both upper-extremity lesions. The development of outcome changes during the radiation treatment could be divided into 5 stages： the period of pigmentation, local swelling, decay, scabby and healing. The effective rate of radiation treatment was 96. 1%. Conclusion Radiation therapy is an effective local treatment for classic Kaposi＇s sarcoma, but the development process is different from skin cancer and possesses relatively unique evolutionary process.
