Outcome of patients with relapsed or refractory anaplastic large cell lymphoma who have failed brentuximab vedotin
Bibliographic record
Abstract
Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate that is highly effective in patients with relapsed/refractory anaplastic large cell lymphoma (ALCL). However, survival outcomes following suboptimal response or subsequent relapse are not well known. We conducted a multicenter study analyzing outcomes of patients with relapsed/refractory ALCL who have received BV with a secondary focus on survival after progression following BV. A total of 56 patients were treated with BV for relapsed or refractory ALCL. The overall response rate to BV was 73% with complete response (CR) rate of 46%. The median failure-free survival and overall survival (OS) after BV were 15.5 month and not reached, respectively. The median duration of response was 27.6 months in patients who achieved CR by BV, while the median OS of those who did not achieve CR by BV was 9.5 months. There was no significant difference in OS between those who underwent stem cell transplant (SCT) and those who did not in patients who achieved CR after BV. However, if patients were in PR after BV, SCT was associated with significantly longer OS. Thirty patients experienced progressive disease on BV or required a subsequent treatment. The median OS after BV failure was 2.9 months with 2-year OS of 27.1%. There were seven long-term survivors (≥12 months) following failure. After an adequate response to subsequent salvage therapy, five patients underwent subsequent SCT (three allogeneic and two autologous), four of which were long-term survivors (17+, 25+, 32+, and 50+ months). In conclusion, BV failure is associated with a poor outcome in patients with ALCL, which defines a small but important group with unmet need. SCT may have benefit in patients with relapsed/refractory ALCL who failed BV.

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.
