High-dose chemotherapy and autologous stem cell transplantation for primary refractory or relapsed Hodgkin lymphoma: long-term outcome in the first 100 patients treated in Vancouver
Bibliographic record
Abstract
Beginning in 1985, patients in British Columbia with Hodgkin lymphoma (HL) that was not controlled by conventional chemotherapy routinely underwent high-dose chemotherapy and autologous stem cell transplantation (HD-ASCT). Long-term complications of HD-ASCT have become apparent as more patients survive without recurrence of HL. Data were obtained retrospectively on the first 100 patients that underwent HD-ASCT for HL in Vancouver, focusing on relapse, treatment-related complications, and the occurrence of late events. Fifty-three patients remain alive (median follow-up, 11.4 years [range, 10.0-17.4 years]) with an overall survival (OAS) of 54% at 15 years. OAS was significantly better in patients in first relapse (67%) than in patients with primary refractory-induction failure (39%) and advanced disease (29%) (P = .002). The major cause of death was progression of HL (32% at 15 years). Treatment-related mortality, including death from second malignancy, was 17% at 15 years. Cumulative risk of a second malignancy was 9% at 15 years. Karnofsky performance status was at least 90% in 47 patients although hypogonadism (20 patients), hypothyroidism (12 patients), unusual infections (10 patients), anxiety or depression (7 patients), and cardiac disease (5 patients) were not uncommon in survivors. HD-ASCT can lead to durable remissions in relapsed or refractory HL with acceptable but definite late toxicity. The occurrence of late events necessitates lifelong medical surveillance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
