چکیده انگلیسی
Cell-of-origin determination has emerged as an important prognostic factor for patients initially diagnosed with diffuse large B cell lymphoma (DLBCL). Specifically, the nongerminal center B cell-like (non-GCB) subtype, composed predominantly of the activated B cell-like (ABC) molecular subtype, has been shown to portend poor prognosis because of its more aggressive nature and resistance to standard cyclophosphamide, hydroxydaunorubicin, oncovin, prednisone (CHOP)-like chemotherapy compared with the GCB subtype. The recurrent MyD88 L265P mutation, present in 29% of ABC DLBCL, was reported as an independent poor prognostic factor for patients with newly diagnosed DLBCL. For patients whose disease relapses or is refractory to first-line chemotherapy, high-dose chemotherapy with autologous stem cell transplantation (ASCT) is frequently offered as salvage therapy. However, the impact of MyD88 mutation status on post-ASCT outcome has not been reported. Here, we retrospectively analyzed, with up to 20 years of follow-up, 165 patients who underwent ASCT for relapsed/refractory DLBCL at our institution. We found that MyD88 mutation status did not correlate with overall survival (OS), post-ASCT OS, or progression-free survival (PFS). Patients with non-GCB subtype had significantly worse OS from initial diagnosis and after ASCT. Notably, high International Prognostic Index score was predictive of poor pre- and post-transplant PFS and post-transplant OS.
