BACKGROUND: Existing therapies for recurrent or refractory histiocytoses,
including Langerhans cell histiocytosis (LCH), juvenile xanthogranuloma (JXG),
and Rosai-Dorfman disease (RDD), have limited effectiveness. We report our
experience with using clofarabine as therapy in children with recurrent or
refractory histiocytic disorders, including LCH (11 patients), systemic JXG (4
patients), and RDD (3 patients). METHODS: Patients treated with clofarabine for
LCH, JXG, or RDD by Texas Children's Hospital physicians or collaborators between
May 2011 and January 2013 were reviewed for response and toxicity. RESULTS:
Patients were treated with a median of three chemotherapeutic regimens prior to
clofarabine. Clofarabine was typically administered at 25 mg/m(2) /day for 5
days. Cycles were administered every 28 days for a median of six cycles (range:
2-8 cycles). Seventeen of 18 patients are alive. All surviving patients showed
demonstrable improvement after two to four cycles of therapy, with 11 (61%)
complete responses, 4 (22%) partial responses, and 2 patients still receiving
therapy. Five patients experienced disease recurrence, but three of these
subsequently achieved complete remission. All patients with JXG and RDD had
complete or partial response at conclusion of therapy. Side effects included
neutropenia in all patients. Recurring but sporadic toxicities included prolonged
neutropenia, severe vomiting, and bacterial infections. CONCLUSION: Clofarabine
has activity against LCH, JXG, and RDD in heavily pretreated patients, but
prospective multi-center trials are warranted to determine long-term efficacy,
optimal dosing, and late toxicity of clofarabine in this population.
