Consider plasmapheresis Asymptomatic Observation q2-3 mths yr 1 q3-6 mths > yr 1 WM Progression Symptomatic ASCT ineligible Single agent Chl., F, or Cladribine ASCT eligible Progression R-CP or R-CD or R-CVP or R-CHOP # Progression Progression Re-use R-CP or R-CD or R-CVP or R-CHOP if ≥ 2 years BDR* or R-Bendamustine or R-Thalidomide (If no history or evidence of VTE) Progression Progression Consider Campath Progression Consider plasmapheresis at all stages Salvage + ASCT** Chl. – Chlorambucil, C – Cyclophosphamide, R – Rituximab, F – Fludarabine P – Prednisolone, D – Dexamethasone, H – Doxorubucin, VTE – Venous Thrombo-embolism # R may cause IgM flare which can last a few months. May need to consider omitting for 1 -2 courses *BDR – Bortezomib + Dexamethasone + Rituximab (Particularly useful for rapid reduction of IgM levels). Funding requests for 2 cycle blocks (to a maximum of 8 cycles) subject to demonstration of objective and ongoing response(s). ** May need to be considered earlier in the pathway in the event of rapid progression + younger age or high grade transformation. An allograft may be considered in very select situations. MCCN WM treatment pathway, April 2011 (due for review April 2012) Page 2 of 2
