Hi all. My husband, 49 yrs old, has mantle cell lymphoma. He has currently taken two sessions of Bendamustine/Rituximab. He will be getting an ASCT by end of 6 sessions. It has been brought to our attention that Bendamustine could have a toxic effect on stem cells. Other doctors are asking us to switch to RCHOP/ RDAP regimen especially that my husband is young with no comorbidities. Is anyone aware of that? Can a person switch regimens?
