Background: DLBCL is the most common type of non-Hodgkin lymphoma in Asia and Indonesia. DLBCL, based on cell of origin is divided into germinal center B-cell-like (GCB) and non-GCB subtypes. 20% of patients have a molecular profile double expressor lymphoma (DEL), which has a worse prognosis. The study aims to determine the relationship between DEL subtypes and cell of origin subtypes with clinical stage and 3-year overall survival of double large B-cell lymphoma (DLBCL) patients in Kariadi General Hospital Semarang. Methods: This study sample was 36 DLBCL patients in Kariadi General Hospital from January to September 2017. The data collection including age of diagnosis, location, stage, cell of origin subtype, DEL subtype and 3-year overall survival. Data analysis using chi-square test and Kaplan Meier curve. Results: DLBCL DEL subtype patients were significantly associated with advanced-stage (p: 0.028). DLBCL non-GCB subtype and DEL subtype patients had a 3-year overall survival that was significantly worse than GCB subtype and non-DEL subtypes (p: 0.026 and p: 0.006, respectively), with a 3-year survival rate of non-GCB subtypes was 38.9% and DEL subtypes were 33.3%. DLBCL patients with advanced stages also have a 3-year overall survival significantly worse than the early stage (p: 0.000), with a 3-year survival rate of 14.3%. Conclusion: DLBCL non-GCB subtype patients, DEL subtypes and advanced stages have a lower 3-year overall survival rate and thus have a worse prognosis
