In the positron emission tomography (PET) era, traditional prognostic factors may not apply for patients with relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL) undergoing autologous stem cell transplantation (ASCT). Moreover, little is known about prognostic factors in patients transplanted for transformed indolent lymphoma (TIL). We conducted a retrospective study of 143 patients with R/R DLBCL and TIL who were transplanted in the last decade and had a post-salvage PET scan. We examined prognostic factors in both groups, and constructed a prognostic score for DLBCL patients. For patients with DLBCL, post-salvage PET response was an important prognostic factor. Advanced age and symptomatic relapse were also significantly associated with outcome. A simple score could stratify patients into three risk groups with 4-year post-ASCT overall survival of 84%, 59%, and 10%, and 4-year progression-free survival of 67%, 41% and 0% (P<0 center dot 0001 for both). However, none of those factors (including PET response to salvage) appeared relevant for patients with TIL, despite their comparable overall outcome. Our prognostic score for DLBCL patients undergoing ASCT may be useful for prognostication, for stratification in clinical trials, and to motivate the design of new strategies for patients in the high-risk group, who may not derive benefit from standard ASCT.
