Bcl-3/IgH translocation (14;19)(q32;q13) in Non-Hodgkin's Lymphomas
Bibliographic record
Abstract
The recurrent cytogenetic (CG) abnormality t(14;19)(q32;q13) involving the oncogene BCL3 is described in patients with atypical chronic lymphocytic leukemia (CLL). We report four patients with non-Hodgkin's lymphoma (NHL) bearing t(14;19). All cases were female and their age ranged from 62 to 91. Histologically, there were two cases of small lymphocytic lymphoma (SLL), both CD11c positive with atypical morphology, one case of Burkitt like lymphoma (BLL), and one case of diffuse large cell lymphoma (DLC-L). One SLL patient showed t(14;19) as the sole abnormality and experienced a benign course for 8 years. The other three cases showed secondary CG progression, including tetraploidy, del(6q), t(8;22) and del(13q). These cases were aggressive in clinical behavior, including an SLL case which transformed to DLC lymphoma in 4 months. Southern analysis and long distance PCR confirmed BCL3/IgH Calpha translocation in one case. We propose that NHLs with t(14;19) may have evolved from the same spectrum of disease as atypical CLL. The poor prognosis of t(14;19) disease is associated with the occurrence of recurrent secondary CG changes, commonly found in B cell lymphoproliferative diseases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
