title: [Total skin electron beam irradiation in cutaneous T-cell lymphoma].
abstract: OBJECTIVE
  Patients with cutaneous T-cell lymphoma are treated in Germany mostly by dermatological local therapy like corticosteroids or PUVA-irradiation. Total skin electron beam irradiation is used rarely, even though it has a potentially curative character. We present an analysis of patients, who received a total skin electron beam irradiation after having progressive disease following other treatment modalities.
  
  
  METHODS
  Twenty-one patients (mean age 58.9 years) in different stages were treated (stage IB and IIA n = 4, stage IIB n = 8, stage III n = 3, stage IV n = 6). All patients had progressive disease under other forms of local therapy. The irradiation was performed from 6 directions per hemibody using 2 axial fields which have each an 18 degree angle to the horizontal level. Six and 7 MeV fast electrons were used. Total dose was between 8 and 36 Gy in single dosis of 1 x 4 up to 5 x 2 Gy per week. In underdosed areas and areas of tumors of the skin boost irradiation with small fields was given.
  
  
  RESULTS
  All patients had a good tumor regression (complete remission: n = 10, partial remission: n = 11). With the follow-up between 4 and 93 months total- and recurrence-free survival was 18 and 7 months (median). Patients in early stages with slow but complete remission of the symptoms had the best prognosis. Because of the small case number there was no significant difference between the groups. There were no severe side effects of the radiotherapy noted.
  
  
  CONCLUSIONS
  Our analysis shows on a small patient number, that total skin electron beam irradiation has a good palliative effect on patients who have progressive disease following other types of treatment like PUVA or corticosteroids. The recurrence-free survival of 2 out of 4 patients with early stage disease (I-IIA) up to 93 month shows the potentially curative character of the treatment.
