title: Recurrent lymphomatous meningitis treated with intra-CSF rituximab and liposomal ara-C.
abstract: BACKGROUND
  The most frequent central nervous system complication of systemic non-Hodgkin's lymphoma (NHL) is lymphomatous meningitis (LM).
  
  
  OBJECTIVE
  A clinical series to test the feasibility of combining intra-CSF liposomal ara-C and rituximab for the treatment of recurrent LM.
  
  
  METHODS
  Clinical series of 14 patients with CSF positive lymphomatous meningitis.
  
  
  METHODS
  Tertiary-care university medical center.
  
  
  RESULTS
  Fourteen patients with recurrent, cytologically positive lymphomatous meningitis were treated. All 14 received liposomal ara-C and rituximab utilizing an Ommaya reservoir. Six patients also received involved-field radiotherapy (brain only two patients; brain and spine two patients; spine only two patients). Best response to treatment included 10 partial responses and four with progressive disease. Estimated median duration of response was 4.0 months (range 1-6 months). Survival ranged from 1.5 to 7 months with an estimated median of 5 months, four patients remain alive and continue to be followed. Cause of death was progressive neurological disease in 7, systemic disease in 1, and combined systemic and neurological disease in 2 patients.
  
  
  CONCLUSIONS
  The combination of intra-CSF liposomal ara-C and rituximab administered in this schedule appears to have no additive toxicity and has modest palliative activity in patients with recurrent LM.
