Abstract Abstract 5013 Introduction Primary mediastinal large B-cell lymphoma (PMBCL) was formally established as a distinct subtype of diffuse large B-cell lymphoma (DLBCL). Some studies indicated that patients with PMBCL have an aggressive clinical course with short median survival but more recent studies reported a relatively good response rate and survival. Therefore, controversies still exist regarding the response to therapy and prognosis of patients with PMBCL. Patients and methods Between July 1993 and July 2008, a total of 26 patients with PMBCL were identified at Asan Medical Center, Seoul Korea. We retrospectively reviewed the clinic-pathologic features and clinical outcomes of them in comparison with 597 patients diagnosed with non-mediastinal DLBCL during the same period. Result Out of the 26 patients, 17 (65.4%) were females and 9 (34.6%) males, while out of the 597 patients, 257 (43.0%) were females and 340 (57.0%) males (p=0.025). The median age of the PMBCL patients was 31.5 years old (range 15-78 years old), while that of the DLBCL patients was 56.0 years old (range 15-85 years old). Out of the 26 patients, 14 (53.8%) had a Ann Arbor stage III or IV disease, 7 (26.9%) had B symptoms, and by the IPI, 11 were in low, 9 in low intermediate, 2 in high-intermediate and 4 in high risk group. Out of 24 patients treated with front-line therapy CHOP or R-CHOP, 17 (70.8%) reached a CR, while 1 PR patient reached a CR after being treated with high-dose chemotherapy followed by autologous stem cell transplantation. Five refractory patients were treated with high-dose chemotherapy followed by autologous stem cell transplantation, but among them only one reached a CR and 4 died of disease progression. With a median follow-up of 41.5 months (range 1-92 months), 5-year survival rates of PMBCL and non-mediastinal DLBCL patients were 69% and 65.7%, respectively (p=0.982, Log Rank). Conclusion There was no difference between PMLBL and non-mediastinal DLBCL in terms of clinical features and outcomes. Disclosures No relevant conflicts of interest to declare.

e19030 Background: High-dose chemotherapy followed by autologous stem cell transplantation (HDC/ASCT) is standard of care for patients with diffuse large B-cell lymphoma (DLBCL) whose diseases relapse after, or are refractory to, first-line therapy. However, there are still high rates of relapse following ASCT, and non-relapse mortality also affects survival rates. Prognostic indicators are therefore needed to identify the best candidates for HDC/ASCT. Methods: We retrospectively analyzed medical records of 111 DLBCL patients (78 relapsed, 33 refractory) who underwent HDC/ASCT at the University of California Los Angeles from 2010-2015. Results: The median age at the time of ASCT was 61 years (IQR 51.5-68.0). 80 patients (72%) had DLBCL in a complete response at the time of ASCT, and the majority (98 patients, 88%) had ECOG performance status of 0-1. After a median follow-up of 4.6 years (IQR 2.2-8.1), the 1-year progression-free survival (PFS) rate was 77.3% (95% CI 69.7%-85.7%) and the 1-year overall survival (OS) rate was 84.7% (95% CI 78.2%-91.7%). 41 patients (37%) relapsed after ASCT with a median PFS of 11 months (IQR 5.0-20.0). 37 patients (33%) died, 23 (21%) from relapse mortality, 11 (10%) from non-relapse mortality, and 3 (3%) from unknown cause of death. In univariate analysis, 2 variables were significantly associated with curtailed PFS and OS: higher number (≥ 3 vs < 3) of chemotherapy regimens prior to ASCT (HR 2.20, 95% CI 1.19-4.06, p = 0.013 for PFS; HR 2.01, 95% CI 1.06-3.84, p = 0.036 for OS) and higher International Prognostic Index (IPI) score at time of ASCT (trend HR 1.61, 95% CI 1.10-2.35, p = 0.018 for PFS; trend HR 2.02, 95% CI 1.37-2.98, p = 0.001 for OS). Higher National Comprehensive Cancer Network (NCCN) IPI score at time of ASCT (trend HR 2.29, 95% CI 1.34-3.90, p = 0.002) and refractory versus relapsed disease (HR 1.99, 95% CI 1.04-3.82, p = 0.038) were also significantly associated with curtailed OS. Conclusions: Our study suggests that IPI, while a validated prognostic tool at diagnosis, is also a prognostic indicator at time of ASCT for PFS and OS. NCCN IPI at time of ASCT was also found to be predictive of OS. Age-adjusted IPI was not associated with outcome following ASCT.
