Treatment of Elderly Hodgkin's Lymphoma Patients with a Novel 5-drug Regimen (ODBEP): A Phase II Study
Bibliographic record
Abstract
Elderly patients with Hodgkin's lymphoma (HL) have a worse outcome than young patients. In an effort to improve the outcome in elderly HL patients, we used a 5-drug chemotherapy regimen called ODBEP (vincristine, doxorubicin, bleomycin, etoposide, prednisone) from 1986-1995. We hoped that by increasing dose intensity through delivery of treatment without delays, and increasing the number of non-cross-resistant chemotherapeutic drugs that were selected for minimal cumulative myelotoxicity, we might improve the cure rate in elderly patients with Hodgkin's lymphoma. Comparison was made with a similar group of patients treated from 1981-1986 with MOPP/ABV-variant chemotherapy. Ninety-nine patients who were 65 years or older, were diagnosed with HL from 1981-1995. Seventy-one patients had advanced disease and 55 of this group were treated with curative intent using multi-agent chemotherapy (ODBEP = 38; MOPP/ABV-variant = 17). ODBEP and MOPP/ABV-type treatment gave a median survival of 43 and 39 months, with 5-year overall survival (OS) of 42 and 32%, respectively. There was no statistically significant difference in OS or disease specific survival between the treatments. Both treatments were well tolerated, but ODBEP was less myelotoxic. ODBEP patients had a relative risk of 0.47 of developing febrile neutropenia compared to the MOPP/ABV-variant patients. In conclusion, treatment of elderly Hodgkin's lymphoma patients with ODBEP resulted in a similar OS and disease-specific survival compared to those treated with MOPP/ABV type chemotherapy, but appeared to be less toxic.

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.
