Systemic Rituximab in Multifocal Primary Cutaneous Follicle Centre Lymphoma

The aim of this retrospective study was to assess the efficacy and tolerance of intravenous rituximab in multifocal primary cutaneous follicle centre lymphomas (PCFCL). Eleven patients with a multifocal PCFCL were treated with rituximab (MabThera(®)) administrated intravenously. After four infusions, an objective response was observed in 90% of patients, and one month after all the infusions (median of 6 infusions) all the patients had an objective response and complete remission was obtained in 7 of 11 patients (64%). Follow-up ranged from 9 to 65 months (median: 30 months). Local disease recurrence was observed in five patients. The median progression-free survival time after the end of treatment was 23.6 months. This study is the largest series of patients with multifocal primary PCFCL treated with intravenous rituximab. This therapy is a safe and effective treatment and could represent an excellent alternative treatment to radiotherapy.
