Flow cytometry in the bone marrow evaluation of follicular and diffuse large B-cell lymphomas.

Abstract

We conclude that FC is just as sensitive or perhaps slightly more sensitive than histology in the detection of bone marrow involvement in FL and DLBCL. FC studies may be warranted in those cases in which the morphology is not diagnosed. The clinical relevance of the small clonal B-cell population in patients without histologic bone marrow involvement (BM(-)/FC(+) cases) remains an open question.
