Despite this progress, however, many patients develop refractory or recurrent DLBCL and then undergo autologous hematopoietic stem cell transplantation (AuHCT). It is unclear to what extent pre-transplant exposure to rituximab affects outcomes after AuHCT Outcomes of 994 patients receiving AuHCT for DLBCL between 1996 and 2003 were analyzed according to whether rituximab was (n = 176; +R cohort) or was not (n = 818; -R cohort) administered with front-line or salvage therapy before AuHCT The +R cohort had superior progression-free survival (PFS; 50% vs 38%; P = .008) and overall survival (OS; 57% vs 45%; P = .006) at 3 years. Platelet and neutrophil engraftment were not affected by exposure to rituximab. Nonrelapse mortality (NRM) did not differ significantly between the 2 cohorts. In multivariate analysis, the +R cohort had improved PFS (relative risk of relapse/progression or death, 0.64; P <.001) and improved OS (relative risk of death, 0.74; P = .039). We conclude that pre-transplant rituximab is associated with a lower rate of progression and improved survival after AuHCT for DLBCL, with no evidence of impaired engraftment or increased NRM. 2011-05-10T01:50:22.682Z ]]> http://nova.newcastle.edu.au/vital/access/manager/Repository/uon:5007 To compare the clinical outcomes of older (age ≥55 years) non-Hodgkin lymphoma (NHL) patients with younger NHL patients (<55 years) receiving autologous hematopoietic cell transplantation (HCT) while adjusting for patient-, disease-, and treatment-related variables, we compared autologous HCT outcomes in 805 NHL patients aged ≥55 years to 1949 NHL patients <55 years during the years 1990–2000 using data reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). In multivariate analysis, older patients with aggressive histologies were 1.86 times (95% confidence interval [CI] 1.43-2.43, P<.001) more likely than younger patients to experience treatment-related mortality (TRM). Relative death risks were 1.33 times (CI 1.04-1.71, P=.024) and 1.50 times (CI 1.33-16.9, P<.001) higher in older compared to younger patients with follicular grade I/II and aggressive histologies, respectively. Autologous HCT in older NHL patients is feasible, but most disease-related outcomes are statistically inferior to younger patients. Studies addressing supportive care particular to older patients, who are most likely to benefit from this approach, are recommended. 2010-04-27T04:45:36.550Z ]]>
