Disease progression after R-CHOP treatment associated with the loss of CD20 antigen expression

Disease progression after R-CHOP treatment associated with the loss of CD20 antigen expression

A case of a follicular lymphoma transformed into a CD20+ is described which progressed with the loss of CD20 expression after 8 cycles of R-CHOP. This phenomenon is not a rare event and has shown poor prognosis. Our purposes are to describe this event and suggest biopsy in relapsed or progressive disease.
