Favourable Overall Survival with Myeloablative Allogeneic Stem Cell Transplantation for Follicular Lymphoma.
Bibliographic record
Abstract
Abstract Introduction Allogeneic stem cell transplantation (Allo-SCT) remains an option for patients with follicular lymphoma (FL). Our program employs a strategy using allo-SCT for patients (pts) with high risk disease based on clinical characteristics. We performed a retrospective analysis to examine long-term disease control and treatment-related mortality. Methods 41 pts with indolent FL (follicular small cleaved [FSC], follicular mixed [FM] or FL grade 1,2 by WHO criteria) underwent allo-SCT at our institution between Jan 1989 and Dec 2005. Patients were in a chemosensitive remission at the time of SCT. The conditioning regimen consisted of busulfan (1 mg/kg PO q6h X4 days between 1989–200 and 3.2 mg/kg IV daily X 4days subsequently) and cyclophosphamide 60 mg/kg X 2 days. Cyclophosphamide 60 mg/kg X 2 days and TBI 12 Gy was used for unrelated donor SCT. GVHD prophylaxis was with cyclosporine A and methotrexate. Results There were 21 males and 20 females. The median age at the time of transplant was 45 years (range 24 to 58). Histologic subtype was: unclassified indolent FL: 3, Grade 1 or FSC: 17, Grade 2 or FM: 21. The median number of prior chemotherapy regimens was 2 (range 1 – 6) and was unavailable in 5. Prior anthracycline: 37, prior purine analog: 9, prior platinum-based: 20, prior auto-SCT: 1, prior rituximab: 11. The median time from diagnosis to allo-SCT was 23 months (range 6 – 161). 38 pts received BuCy conditioning. 2 patients underwent RIC SCT. Graft source was: matched related (MRD) bone marrow (BM): 28, MRD peripheral blood stem cells (PBSC): 4, Mismatch related (MMRD) bone marrow (BM): 1, MMRD PBSC: 2, matched unrelated donor (MUD) BM: 1, MUD PBSC: 1, and syngeneic BM: 4. The five year overall survival is 77% (95% confidence intervals 73 – 91%) with a median follow-up of 48 months post-SCT. Treatment-related mortality was 5 of 41 pts (12%). Non-relapse mortality was seen in one patient (3%). One patient has relapsed at over 3 years post-SCT while all recipients of syngeneic SCT remain in remission. Conclusions These results demonstrate that in selected patients, a fully myeloablative allo-SCT utilizing Busulfan-Cyclophosphamide conditioning provides excellent overall survival and disease control with low TRM. Prospective comparisons of RICSCT with myeloablative SCT should be performed in order to better evaluate these strategies.

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.
