Hi! My husband was diagnosed with FL a year and a half ago. This isn’t what you asked, but thought I’d join in with you. At diagnosis his bloodwork was all within normal parameters. Five rounds of Rituxan together with four rounds of bendamustine and after that his IgG, IgM, and gammaglobulin are low. His hematologist says that it should turn itself around with time. The great side effect of all this is that his last two PetScans showed no evidence of disease! He has a Deauville score of 1. As Lori would say “he is unremarkable”!!! Next scan is in September. Hoping for the best for you!!
