R-dmCODOX-M/IVAC

R-dmCODOX-M: Rituximab, dose-modified Cyclophosphamide, Oncovin, DOXorubicin, Methotrexate
IVAC: Ifosfamide, Vepesid (etoposide), Ara-C (cytarabine)

Regimen #1, Mead et al. 2008 & Kassam et al. 2012

Kassam et al. 2012 is a retrospective analysis that includes analysis of the use of rituximab with dose-modified CODOX-M/IVAC, and it lists Mead et al. 2008 as its reference for this. However, since Mead et al. 2008 did not include the use of rituximab, and Kassam et al. 2012 did not describe exactly how rituximab was used in addition to that cited regimen, rituximab will not be included in this summary of the regimen. If one were to speculate, one would presume the dosage & schedule would be Rituximab (Rituxan) 375 mg/m2 IV once per cycle.

Regimen #2, Lacasce et al. 2004 & Barnes et al. 2011 - modified Magrath

Lacasce et al. 2004 describes this particular modified Magrath regimen, and Barnes et al. 2011 references it as the foundation for its R-CODOX-M/IVAC regimen. There were several vague details/errors in Lacasce et al. 2004 that limit one's ability to confidently use this regimen.

• Patients are stratified into high and low risk:
  • Low risk patients must fulfill both of the following criteria:
    • Normal LDH
    • Single focus of disease measuring <10 cm in greatest diameter
  • Any patients which do not meet low risk criteria are classified as high risk

Part A: R-CODOX-M

• Rituximab (Rituxan) 375 mg/m2 IV once per cycle (no day specified by Barnes et al. 2011)
• Cyclophosphamide (Cytoxan) 800 mg/m2 IV once on days 1 & 2
• Vincristine (Oncovin) 1.4 mg/m2 (maximum dose of 2 mg per cycle) IV once on days 1 & 10
• Doxorubicin (Adriamycin) 50 mg/m2 IV once on day 1
• Methotrexate (MTX) 3000 mg/m2 IV (no duration of infusion given) on day 10
  • Note: Lacasce et al. 2004 says that methotrexate is given after urine is alkalinzied to a pH <7; this is almost certainly a typo, and it was probably intended to say "alkalinzied to a pH >7"

CNS prophylaxis:

• Cytarabine (Cytosar) 50 mg intrathecal once on days 1 & 3
  • Day 3 dose is not given to low risk patients
  • Hydrocortisone 50 mg intrathecal administered with all doses of intrathecal chemotherapy
• Methotrexate (MTX) 12 mg intrathecal once on day 1, admixed with day 1 cytarabine
  • Hydrocortisone 50 mg intrathecal administered with all doses of intrathecal chemotherapy

Patients with CNS disease at presentation received the following extra doses of intrathecal chemotherapy during cycle 1:

• Cytarabine (Cytosar) 50 mg intrathecal once on day 5 (in addition to doses above)
• Methotrexate (MTX) 12 mg intrathecal once on day 10 (in addition to dose above)
• Hydrocortisone 50 mg intrathecal administered with all doses of intrathecal chemotherapy

Supportive medications:

• Folinic acid (Leucovorin) 200 mg/m2 IV once on day 11, starting 24 hours after the start of the day 10 Methotrexate (MTX), then 15 mg/m2 IV every 6 hours thereafter until serum methotrexate level is <0.1 x 10^-6 M
• G-CSF (no dose specified) on days 3-8
  • Note: Lacasce et al. 2004 says that "G-CSF was restarted therafter if ANC > 1000"; this is believed to be a typo. The authors probably intended to say "G-CSF was restarted therafter if ANC <1000." Additionally, figure 1 contradicts the body text and indicates that G-CSF is given on days 1 to 6, and restarted on day 12: "ANC <1000 on day 12, restart G-CSF."

Part B: R-IVAC

• Rituximab (Rituxan) 375 mg/m2 IV once per cycle (no day specified by Barnes et al. 2011)
• Ifosfamide (Ifex) 1500 mg/m2 IV once daily on days 1 to 5
• "Equal-dose" Mesna (Mesnex) as compared to ifosfamide, in divided doses
• Etoposide (Vepesid) 60 mg/m2 IV once daily on days 1 to 5
• Cytarabine (Cytosar) 2000 mg/m2 IV every 12 hours on days 1 & 2 (total of 4 doses per cycle)

CNS prophylaxis:

• Methotrexate (MTX) 12 mg intrathecal once on day 5

Patients with CNS disease at presentation received the following extra doses of intrathecal chemotherapy during the first cycle of IVAC (cycle 2 overall):

• Cytarabine (Cytosar) 50 mg intrathecal once on days 3 & 5
• Methotrexate (MTX) 12 mg intrathecal once on day 5
  • Note: Lacasce et al. 2004 said that these are additional doses, but there is already a dose of methotrexate 12 mg intrathecal regularly scheduled to be given on day 5. Therefore, it is unclear whether a second dose of methotrexate 12 mg is to be given.
• Hydrocortisone 50 mg intrathecal administered with all doses of intrathecal chemotherapy

Supportive medications:

• G-CSF (no dose specified), starting on day 6, given until "neutropenia resolved"
• Dexamethasone (Decadron) eye drops with cytarabine

High risk patients receive Part A: CODOX-M and Part B: IVAC given in an alternating fashion x total of 4 cycles (A, B, A, B). Low risk patients receive Part A: CODOX-M x 3 cycles only. Each cycle starts on the same day that the patient's ANC is >1,000/uL.
