Conclusions-BTG 2013
  • Certainly still a role for watchful waiting
  • R-FM a/w increased toxicity
  • B-R is less toxic and more effective than CHOP-R
  • Impressive data with frontline IMiD R
  • Maintance rituximab
  • Observed improvements in PFS and Time to Next Tx
  • not been shown to translate into OS benefit
  • MR should be weighed against increased risk of
    toxicity, other potential complications,
    resources and pts preference
