Concordance between molecular results and microscopic BM involvement of B cell neoplasia (n=119) and T cell neoplasia (n=29).
BM involvement of lymphoid neoplasm |
Ig rearrangement(B cell neoplasia) | TCR rearrangement(T cell neoplasia) | ||
---|---|---|---|---|
Positive | Negative | Positive | Negative | |
Positive | 25(21.0%) | 6(5%) | 6(20.7%) | 0(0%) |
Negative | 29(24.4%) | 59(49.6%) | 14(48.3%) | 9(31%) |
Ig/TCR rearrangement negative means: no specific product, polyclonal or pseudoclonal. Ig/TCR rearrangement positive means: clonal or clonal with a polyclonal background.
