Abstract
INTRODUCTION: Multiple therapeutic strategies have been proposed for the management of primary cutaneous lymphomas. We report the outcome data and therapeutic response of a group of patients treated with local radiotherapy. MATERIAL AND METHODS: Twenty seven patients with diagnostic of cutaneous lymphoma and treated with local radiation were evaluated for clinical response. Thirteen cases corresponded to cutaneous T-cell lymphomas (CTCL) and 14 to cutaneous B-cell lymphomas (CBCL). Orthovoltage radiotherapy of 100 Kv was used and total dose of radiation ranged from 15 to 30 Gy (mean 24 Gy; median 20 Gy). RESULTS: The immediate response to the treatment was satisfactory in all cases. In 24 patients (89%) complete response was obtained in the irradiated lesion and in 3 cases (11%) the response was partial. With a mean follow-up of 25.4 months (range 1-100 months) the overall response rate was 96.3%. Fourteen patients (52%) were alive without evidence of disease (6 CTCL and 8 CBCL), 5 patients (18%) retained cutaneous disease or had systemic progression (3 CTCL and 2 CBCL) and 8 patients died (30%). In 7 patients lymphoma progression was the factor leading to death (26%) and in one patient the cause was not related with the disease. CONCLUSIONS: Radiotherapy was demonstrated to be able to induce clinical remission of primary cutaneous lymphomas.
