METHODS Thirty patients with cutaneous B-cell lymphoma （CBCL） were treated by cutaneous irradiation based on the number and location of the lesions and the stage of their tumor. Treatment was conducted using a Satume Clinac. RESULTS A complete response （CR） from the treatment for our series was 86%. The length of complete remission ranged from 4 to 301 months. Three patients （11%） developed a partial response （PR）. One patient was progressive. Disease-free survival（DFS） at 10 years was 87%. Three patiens died [One PCMZL two PCLBCL leg type （29%）]. Radiotherapy was generally well tolerated. CONCLUSION According to the WHO/EORTC classification, the survivor results were good for PCMZL and PCFCL. The PCLBCL leg type had a poor prognosis. Localized field irradiation is an effective treatment for some localized forms of primary cutaneous B-cell lymphoma, and this mode of therapy can produce prolonged remissions.The patients with wide-spread skin involvement are usually candidates for extended field irradiation and/or chemotherapy. For advanced stages of cutaneous B-cell lymphoma, where chemotherapy is the treatment of choice, a degree of palliation can be achieved using local field irradation.展开更多
