NOTE: *Patients with minimal disease (i.e., a single lymph node ≤ 2 cm in maximal horizontal diameter or a > 75% reduction in a bulky (≥ 10 cm) tumor mass AND no morphological evidence of active bone marrow disease) at initial evaluation do not receive the first high-dose chemotherapy but proceed directly to peripheral blood stem cell (PBSC) mobilization with filgrastim (G-CSF) for 3 days and PBSC collection beginning on day 4.
