title: [Prolonged remission after immunotherapy of a previously refractory peripheral T-cell non-Hodgkin lymphoma].
abstract: METHODS
  A 54-year-old woman in good condition was admitted because of a rapidly growing tumor in the right groin with skin infiltration. There were no B-symptoms and no increased susceptibility to infections.
  
  
  METHODS
  Histology revealed a peripheral T cell non-Hodgkin lymphoma (NHL). Laboratory tests showed borderline elevation of lactate dehydrogenase. Staging computed tomography (CT) revealed widespread moderately enlarged lymph nodes and the main lesion in right groin measuring 5 x 6 cm which was classified as stage IIIAE.
  
  
  METHODS
  According to the phase-II-trial DSHNHL-2003 - 1 (German study group for high grade NHL) the patient was scheduled for cycles of CHOEP at 14-day intervals plus granulocyte colony stimulating factor. During the first cycle she developed a worsening wound infection and an infection of her port catheter. Because response to treatment was only minimal a biopsy was performed which showed persisting malignant lymphoma. As a result she was not given the 4-weekly addition of alemtuzumab, as provides in the study protocol. Instead she received alemtuzumab subcutaneously for eight weeks at a dose of 3 x 30 mg/week plus prophylactic antibiotics. A good partial response was obtained, followed by radiotherapy with 36 Gy to the main lesion in the right groin. The follow up CT-scans one year after treatment showed a stable remission.
  
  
  CONCLUSIONS
  In T-NHL with primary non-response it is especially difficult to induce a stable remission. Despite a course which was complicated by infections and a failing response to increased chemotherapy a remission was achieved in this patient with a monotherapy of alemtuzumab for eight weeks without complications, followed by radiotherapy.
