Identical Twin Marrow Transplantation in Multiple Myeloma
Bibliographic record
Abstract
We performed the first successful syngeneic bone marrow transplantation (BM Txp) in a patient with multiple myeloma. The patient and his normal identical twin are 50-year-old physicians. Prior to BM Txp, a partial remission was achieved with 1 year of continuous low dosage melphalan and prednisone therapy. Immediately before BM Txp, high dose cyclophosphamide and total body irradiation were administered in an attempt to eradicate the residual tumor. For 17 months after BM Txp, the patient was asymptomatic and hematologically normal although a low concentration of serum monoclonal IgGK persisted. In the 18th month, recurrence of bone pain and increase in the monoclonal IgG signalled exacerbation of the disease. Chemotherapy was resumed and again produced objective and subjective evidence of response. This study demonstrates the feasibility and potential usefulness of syngeneic BM Txp in myeloma.

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.
