Survival and Late Effects in Children With Hodgkin's Lymphoma Treated With MOPP/ABV and Low-Dose, Extended-Field Irradiation
Bibliographic record
Abstract
PURPOSE: Reduced-intensity protocols for pediatric Hodgkin's lymphoma are aimed at preserving excellent relapse-free survival while decreasing the incidence of late effects. PATIENTS AND METHODS: We retrospectively reviewed the outcome of 123 children treated consecutively for Hodgkin's lymphoma at a single institution. Patients with stages I-IIIB disease received three cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)/ doxorubicin, bleomycin, and vinblastine (ABV) followed by 15 Gy of extended-field irradiation, while those with stage IV disease were treated with six to eight cycles of MOPP/ABV chemotherapy with or without radiotherapy. RESULTS: At a median follow-up of 8.5 years (range, 1.4 to 15.5 years), the estimated 10-year overall survival and event-free survival are 94% (SE, 2.2%) and 88% (SE, 3.1%) respectively. There have been 12 treatment failures and six disease-related deaths. A very large mediastinal mass ( 50% of the maximal thoracic diameter) was associated with a 10-year event-free survival of 50% (SE, 14%) compared with 91% (SE, 4.0%) for smaller masses (P < .001). Late cardiopulmonary toxicity is largely absent, and the incidence of hypothyroidism is 14%. There have been no cases of secondary leukemia and four secondary solid malignancies observed to date. CONCLUSION: MOPP/ABV and low-dose, extended-field radiotherapy is an effective treatment for pediatric Hodgkin's lymphoma. With median follow-up of 8.5 years, late cardiopulmonary effects and secondary malignancies from this treatment regimen are infrequent. Continued longitudinal observations, particularly for breast cancer in female patients and gonadotoxicity, will determine whether the goal of decreasing treatment-related complications while maintaining excellent survival has been achieved.

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.
