<jats:title>Summary</jats:title><jats:p>Patients with germinal center B cell‐like (GCB) and non‐GCB diffuse large B cell lymphomas (DLBCL) receiving first line therapy have distinct prognosis. We explored the differences in outcome following salvage autologous hematopoietic stem cell (HSC) transplantation between patients with GCB and non‐GCB DLBCL. Forty‐four patients with relapsed and 15 patients with primary refractory chemosensitive disease undergoing BEAM (BCNU [carmustine], etoposide, cytarabine, melphalan) conditioning and autologous HSC were included. Immunohistochemical analysis was performed for CD10, BCL‐6, MUM1 (allowing classification into GCB and non‐GCB‐like DLBCL) and BCL‐2. Median follow‐up of survivors was 25 months; median age at the time of transplantation was 60 years (range 17–77). Thirty‐two patients (54%) were classified as having GCB and 27 (46%) as having non‐GCB‐like DLBCL. Patients with GCB and non‐GCB DLBCL did not differ in the risk of progression after HSC transplant (<jats:italic>P</jats:italic> = 0·78) or overall survival (<jats:italic>P</jats:italic> = 0·48). In multivariate analysis, only time to progression after initial treatment impacted overall survival. We conclude that patients with relapsed or primary refractory chemosensitive GCB and non‐GCB‐like DLBCL derive similar benefit from autologous HSC transplant.</jats:p>
