OBJECTIVES: I. Evaluate the response to a 8 week induction chemotherapy program consisting of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with mantle cell lymphoma. II. Evaluate the efficacy of ifosfamide, carboplatin, and etoposide (ICE) chemotherapy and filgrastim (G-CSF) for peripheral blood stem cell (PBSC) mobilization in this patient population. III. Evaluate the safety and efficacy of ICE followed by total body irradiation and high dose cyclophosphamide and etoposide in this patient population. IV. Assess the contamination of PBSCs by lymphoma cells following mobilization by chemotherapy and G-CSF in this patient population.
