R-MegaCHOP-ESHAP-BEAM in Patients With High-Risk Aggressive B-Cell Lymphomas

"Given together with induction chemotherapy:~Rituximab - 375 mg/m2 iv every 3 weeks, 4-6 doses"

"cyclophosphamide 3000 mg/m2 iv every 3 weeks, 3 cycles vincristin 2 mg iv every 3 weeks, 3 cycles doxorubicin 75 mg/m2 iv every 3 weeks, 3 cycles Prednisolone 300 mg/m2 divided into five days po every 3 weeks, 3 cycles pegfilgrastim 6 mg sc every 3 weeks.~3 cycles consisting of combination treatment of above mentioned drugs are given."

"Starts three weeks after last cycle of Induction part 1.~Etoposide 240 mg/m2 divided into equal doses for four days, together with methylprednisolone 2000 mg divided into equal doses for four days, together with cisplatin 100 mg/m2 divided into equal doses for four days, and together with cytarabine 2000 mg/m2 iv one dose on 4th day of treatment. Filgrastim 10-12 ug/kg from day five after start of chemotherapy untill stem cell collection.~Peripheral blood progenitor cell collection (PBPC) is started when CD34 positive cells are \>20/cubic milimeter of blood and continued untill 5 million of CD34 positive cells are collected from peripheral blood."

"Part 3 of induction treatment is given approximately one week after the end of Part 2.~Etoposide 240 mg/m2 divided into equal doses for four days, methylprednisolone 2000 mg divided into equal doses for four days, cisplatin 100 mg/m2 divided into equal doses for four days, cytarabine 2000 mg/m2 iv one dose on day 4 of chemotherapy and pegfilgrastim 6 mg on day five of chemotherapy are given twice three weeks apart."

This is called autologous transplantation (ASCT). Filgrastim 5 ug/kg is given from day 14 (start of the chemotherapy being day 1) until neutrophil recovery."

Radiotherapy is started given 4-8 weeks after the autologous transplantation. It is given to patients with initially bulky disease (\>10 cm at diagnosis) or to patients with residual disease after Induction treatment part 1-3 and Consolidation treatment part 1. 30-40 Gy are given in 2 Gy fractions over 3-4 weeks.
