Background We analyzed detailed characteristics and salvage treatment in 175 follicular lymphoma patients from the FL2000 study who were in progression after first-line therapy with or without addition of rituximab to chemotherapy and interferon.Design and Methods The impact of using autologous stem cell transplantation and/or rituximab administration at first progression was investigated, taking into account initial therapy. With a median follow up of 31 months, 3-year event free and overall survival rates after progression were 50% (95%CI 42–58%) and 72% (95%CI 64–78%), respectively.Results The 3-year event free rate of rituximab re-treated patients (n=112) was 52% (95%CI 41–62%) versus 40% (95%CI 24–55%) for those not receiving rituximab second line (n=53) (P=0.075). There was a significant difference in 3-year overall survival between patients receiving autologous stem cell transplantation and those not: 92% (95%CI 78–97%) versus 63% (95%CI 51–72%) (P=0.0003), respectively. In multivariate analysis, both autologous stem cell transplantation and period of progression/relapse affected event free and overall survival.Conclusions Regardless of front-line rituximab exposure, this study supports incorporating autologous stem cell transplantation in the therapeutic approach at first relapse for follicular lymphoma patients.
