Pre-transplant PET/CT may be prognostic in diffuse large B-cell lymphoma (DLBCL) patients undergoing autologous stem cell transplantation (ASCT). We reviewed relapsed and pre-transplant PET/CT scans of 32 patients with DLBCL treated with ASCT to determine the Deauville score and the maximum standardized uptake value (SUV
max ). Patients with a Deauville score of 4 had a significantly inferior prognosis. The 3-year progression-free survival (PFS) for patients with Deauville 1-3 score was 64%, compared to 0% for Deauville 4, while the 3-year overall survival (OS) was 84% and 25%, respectively (p < .001,p = .002). The change in the SUVmax (>66 versus ≤66%) was not predictive of PFS or OS, but a high pre-transplant SUVmax (>6) demonstrated a trend towards an inferior PFS. Pre-transplant PET/CT is a tool for identifying DLBCL patients at high risk for treatment failure with ASCT and could be used to risk-stratify patients in prospective clinical trials of novel transplant strategies.
