Phase II Study of RT-PEPC in Relapsed Mantle Cell Lymphoma

"Induction phase (month 1-3)~• PEPC daily (prednisone 20 mg/day, cyclophosphamide 50 mg/day, etoposide 50 mg/day, and procarbazine 50 mg/day) until expected drop in neutrophil count (ANC \< 3000), unless due to disease. After ANC returns to above 2,000/ul, PEPC resumes at alternate day or fractionated weekly basis.~Maintenance phase (month 4-12) • PEPC QOD or fractionated weekly basis.~Post-Month 12 Maintenance phase (post-month 12 until disease progression)~• PEPC QOD or fractionated weekly basis"

"Induction phase (month 1-3)~• Daily thalidomide at 50 mg/day for the first 8 weeks, then dose escalated as tolerated to a maximum of 100 mg/day.~Maintenance phase (month 4-12) • Daily low dose thalidomide (50-100 mg/d)~Post-Month 12 Maintenance phase (post-month 12 until disease progression)~• Daily low dose thalidomide (50-100mg/d)"

"Induction phase (month 1-3)~• Rituximab weekly x 4 (375 mg/m2/week) starting at week 1.~Maintenance phase (month 4-12) • Rituximab (375 mg/m2/week) weekly x 4 administered every 4 months.~Post-Month 12 Maintenance phase (post-month 12 until disease progression)~• Rituximab (375 mg/m2/week) weekly x 4 administered every 4 months"
