Loss of CD20 Expression after Rituximab Therapy for B-Cell Lymphomas: A Review of the Literature
Bibliographic record
Abstract
Rituximab (Rx), a chimeric anti-human CD20 antibody, is used widely for the treatment of B-cell non-Hodgkin’s lymphomas (NHL) worldwide. Loss of CD20 expression in relapsed B-cell lymphomas after Rx treatment, however, is observed in some cases, which might be a cause of B-cell NHL unresponsiveness to Rx retreatment. The frequency of loss of CD20 expression after Rx treatment and radiotherapy, its correlation with histological changes, and its clinical implication together with possible molecular mechanisms are discussed in this review of pertinent literature. In high-grade B-cell NHL, loss of CD20 expression after Rx treatment was observed less frequently in Japan than in Australia. Evaluation of CD20 expression by immunohistochemical and flow cytometric methods is a reliable guide for employment of Rx treatment for B-cell lymphomas.

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; a candidate call from one teacher head, not a consensus.
