CHOEP + High Dose Therapy + Auto SCT for T-Cell Lymphoma

Objectives: Primary * To estimate the proportion of patients alive and progression-free at 24 months after beginning induction therapy Secondary * To estimate the response rate (complete remission (CR) and partial remission (PR)) after CHOEP x 6 and after Gem/Bu/Mel ASCT * To estimate overall survival (OS), progression-free survival (PFS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM) * To estimate the toxicity (grade 3 and above) * To estimate the rate of successful stem cell mobilization after CHOEP in responding patients * To estimate the proportion of patients who can successfully complete the entire treatment regimen * To estimate the time to engraftment of neutrophil and platelet engraftment after ASCT * To determine whether tumor DNA can be detected in peripheral blood of patients before therapy * To evaluate the changes and prognostic relevance in detectable tumor DNA in peripheral blood after induction chemotherapy (CHOEP) and after Gem/Bu/Mel ASCT
