How do you approach the treatment of hairy cell leukemia with inadequate response to front line therapy?  

If a patient obtains a PR or less to front line cladribine, what factors help you chose between a second course of cladribine, an alternative purine analog, rituximab monotherapy or combination therapy or BRAF-directed therapy with vemurafenib?

Is your choice in above therapy different in the case of variant-HCL?
