Cyclophosphamide and prednisone induction followed by cyclophosphamide mobilization effectively decreases the incidence of engraftment syndrome in patients with POEMS syndrome who undergo stem cell transplantation
Bibliographic record
Abstract
High-dose chemotherapy with autologous stem cell transplantation (ASCT) can achieve excellent clinical responses in patients with POEMS syndrome (Jimenez Zepeda et al., Blood 2010;116:2403; Gertz et al., Am J Hematol 2005;79:319-328; Gherardi et al., Ann Neurol 1994;35:501-505; Gattinoni et al., Nat Rev Immunol 2006;6:383-393; Salem et al., J Immunol 2009;182:2030-2040; Salem et al., Cancer Immunol Immunother 2010;59:341-353; Salem et al., Cell Immunol 2010;261:134-143). However, High-dose melphalan with ASCT should be considered carefully due to its treatment-related morbidity (Vuckovic et al., Blood 2003;101:2314-2317), especially in patients with poor performance status owing to polyneuropathy and multiorgan involvement, such as cardiac, respiratory, and renal failure. Significant increases in the concentration of circulating macrophage colony-stimulating factor, erythropoietin, IL-6, and TNF-α, reach near maximal values at approximately day +12, predating neutrophil engraftment, and clinically manifest with fever, rash and edema (Dispenzieri et al., Eur J Haematol 2008;80:397-406). Depending on the definition used, approximately 50% of patients satisfied criteria for engraftment syndrome (ES) (Vuckovic et al., Blood 2003;101:2314-2317). ES occurs in 27-47% of patients who undergo ASCT; mortality rate is reported from 8% to 18% (Gattinoni et al., Nat Rev Immunol 2006;6:383-393; Vuckovic et al., Blood 2003;101:2314-2317). We have therefore reviewed our experience with ASCT in patients with POEMS syndrome who were treated with cyclophosphamide and prednisone as induction therapy followed by cyclophosphamide mobilization with an emphasis on treatment-related morbidity and frequency of ES. Our study confirms that ASCT is a feasible and efficacious treatment for patients with POEMS syndrome. In addition, the use of CP followed by cyclophosphamide mobilization decreases the incidence of PES leading to less morbidity and mortality rates.

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.
