- Regimen B: Patients who are currently on the MSKCC standard dose salvage therapy protocol with ifosfamide, carboplatin, and etoposide (ICE) for recurrent or refractory IGL receive additional mobilization with G-CSF after completion of the last course of ICE. Patients with recurrent or refractory IGL, immunoblastic lymphoma, or LGL who have not previously received ifosfamide and are not currently on the MSKCC standard dose salvage protocol with ICE receive ifosfamide IV and carboplatin on day 2 and etoposide IV on days 1-3 (standard-dose ICE) followed by G-CSF SC. When blood counts recover, autologous PBSC are harvested and selected for CD34+ cells.
