It is recommended that procarbazine hydrochloride be given only by or under the supervision of a physician experienced in the use of potent antineoplastic drugs. Adequate clinical and laboratory facilities should be available to patients for proper monitoring of treatment.
Note: Refer to individual protocols for specific dosage and interval information. Procarbazine is associated with a high emetic potential (Ref); antiemetics are recommended to prevent nausea and vomiting (Ref). The manufacturer suggests that an estimated lean body mass be used in obese patients and patients with rapid weight gain due to edema, ascites, or abnormal fluid retention.
Hodgkin lymphoma:
MOPP regimen: Note: While procarbazine is approved as part of the MOPP regimen, the MOPP regimen is generally no longer used due to improved toxicity profiles with other combination regimens used in the treatment of Hodgkin lymphoma (Ref). Manufacturer's labeling: Infants, Children, and Adolescents: Oral: 50 to 100 mg/m2/day once daily for 14 days of a 28-day cycle (Ref)
BEACOPP regimen (high-risk): Limited data available: Children and Adolescents: Oral: 100 mg/m2 days 0 to 6 of a 21-day treatment cycle (in combination with bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, and prednisone) for 2 to 4 cycles (Ref)
CNS tumors; low-grade gliomas, WHO grades 1 and 2: Limited data available: TPCV regimen: Children <10 years: Oral: 50 mg/m2 every 6 hours for 4 doses (at hours 60, 66, 72, and 78) during a 42-day cycle (in combination with thioguanine, vincristine, and lomustine) for a total of 8 cycles (Ref)
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
All patients: There are no dosage adjustments provided in the manufacturer's labeling; use with caution; may result in increased toxicity. However, because predominantly inactive metabolites are excreted via the kidneys, dosage adjustment is not necessary (Ref).
All patients: There are no dosage adjustments provided in the manufacturer's labeling; use with caution; may result in increased toxicity. The following adjustments have been reported in literature based primarily on experience in adult patients:
Floyd 2006:
Transaminases 1.6 to 6 times ULN: Administer 75% of dose
Transaminases >6 times ULN: Use clinical judgment
Serum bilirubin >5 mg/dL or transaminases >3 times ULN: Avoid use
(For additional information see "Procarbazine: Drug information")
Dosage guidance:
Safety: Allow a 1-month interval (or longer, based on marrow recovery) between myelosuppressive radiation or chemotherapy prior to initiation of procarbazine.
Dosing: The manufacturer suggests that an estimated lean body mass be used in patients with obesity and patients with rapid weight gain due to edema, ascites, or abnormal fluid retention.
Clinical considerations: Procarbazine is associated with a moderate or high emetic potential; antiemetics are recommended to prevent nausea and vomiting (Ref).
CNS tumors (gliomas: anaplastic oligodendroglioma, oligoastrocytoma, low grade gliomas) (off-label use):
Anaplastic oligodendroglioma, oligoastrocytoma: PCV regimen: Oral: 60 mg/m2 on days 8 to 21 of a 42-day treatment cycle (in combination with lomustine and vincristine; to begin within 4 weeks after radiotherapy) for 6 cycles (Ref) or 75 mg/m2 on days 8 to 21 of a 42-day treatment cycle (in combination with lomustine and vincristine, followed by radiotherapy) for up to 4 cycles (Ref).
Low-grade gliomas: PCV regimen: Oral: 60 mg/m2 on days 8 to 21 of a 56-day treatment cycle (in combination with lomustine and vincristine; after radiotherapy) for 6 cycles (Ref).
Hodgkin lymphoma:
BEACOPP, standard or escalated regimen (off-label dosing): Oral: 100 mg/m2 on days 1 to 7 every 21 days (in combination with bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, and prednisone) for 6 to 8 cycles (Ref). May consider a PET scan after cycle 2 to determine (based on response) if patient is appropriate for reducing the total number of cycles to 4 or 6 eBEACOPP cycles (Ref).
MOPP regimen: While procarbazine is approved as part of the MOPP regimen, the MOPP regimen is generally no longer used due to improved toxicity profiles with other combination regimens used in the treatment of Hodgkin lymphoma.
Non-Hodgkin lymphomas, relapsed or refractory (off-label use):
CEPP regimen: Oral: 60 mg/m2 on days 1 to 10 every 28 days (in combination with cyclophosphamide, etoposide and prednisone) for up to 6 cycles (Ref).

Concerns related to adverse effects:
• Bone marrow suppression: Hematologic toxicity (leukopenia and thrombocytopenia) occurs 2 to 8 weeks after treatment initiation. Allow ≥1 month interval between radiation therapy or myelosuppressive chemotherapy and initiation of procarbazine treatment.
• CNS toxicity: CNS toxicity (eg, paresthesias, neuropathies, confusion) has been observed. CNS depression may occur; use with caution with other agents associated with CNS depression.
• Disulfiram-like reaction: Avoid ethanol consumption during procarbazine therapy, as a disulfiram-like reaction may occur.
• Hemolysis: Procarbazine may cause hemolysis and/or presence of Heinz inclusion bodies in erythrocytes.
• Hemorrhage: Hemorrhage or bleeding may occur.
• Hypersensitivity: Generalized allergic reactions have been reported.
• Secondary malignancies: Procarbazine is possibly carcinogenic; acute myeloid leukemia and lung cancer have been reported following the use of procarbazine in combination with other chemotherapeutic agents.
Concurrent drug therapy issues:
• Monoamine oxidase inhibitor activity: Procarbazine may possess some monoamine oxidase inhibitor (MAOI) activity; the potential for serious drug and food interactions is unclear as there is no clinical evidence to support such interactions; following an MAOI diet (avoid tyramine-containing foods) is recommended.
In pediatric patients, undue toxicity characterized as tremors, coma, and convulsions have been reported rarely; monitor closely with use.

Ethanol: Ethanol may cause a disulfiram reaction. Management: Avoid ethanol.
Food: Concurrent ingestion of foods rich in tyramine, dopamine, tyrosine, phenylalanine, tryptophan, or caffeine may cause sudden and severe high blood pressure (hypertensive crisis or serotonin syndrome). Management: Avoid tyramine-containing foods (aged or matured cheese, air-dried or cured meats including sausages and salamis; fava or broad bean pods, tap/draft beers, Marmite concentrate, sauerkraut, soy sauce, and other soybean condiments). Food’s freshness is also an important concern; improperly stored or spoiled food can create an environment in which tyramine concentrations may increase. Avoid foods containing dopamine, tyrosine, phenylalanine, tryptophan, or caffeine.
Avoid tyramine-containing foods/beverages. Some examples include aged or matured cheese; air-dried, smoked, pickled, or cured meats (including sausages and salamis); fava or broad bean pods; tap/draft beers; ripe bananas; Marmite concentrate; sauerkraut; and soy sauce and other soybean condiments.
Patients who could become pregnant should avoid pregnancy during treatment. In general, patients who could become pregnant should use effective contraception during systemic anti-cancer therapy and for 3 to 6 months after the last dose. Patients with partners who could become pregnant should use effective contraception during treatment and for 3 to 6 months after the last dose of systemic anti-cancer therapy (ESMO [Peccatori 2013]).
Procarbazine is associated with a high risk of azoospermia and infertility (ESMO [Lambertini 2020]). Azoospermia and infertility have been reported with procarbazine when used in combination with other chemotherapy agents.
Recommendations are available for fertility preservation of male and female patients to be treated with anticancer agents (ASCO [Oktay 2018], Klipstein 2020).
Outcome data following maternal use of procarbazine during pregnancy are available (NTP 2013). Procarbazine may cause fetal harm if administered during pregnancy. There are case reports of fetal malformations in the offspring of pregnant patients exposed to procarbazine as part of a combination chemotherapy regimen.
The European Society for Medical Oncology (ESMO) has published guidelines for diagnosis, treatment, and follow-up of cancer during pregnancy. The guidelines recommend referral to a facility with expertise in cancer during pregnancy and encourage a multidisciplinary team (obstetrician, neonatologist, oncology team) approach. In general, if chemotherapy is indicated, it should be avoided in the first trimester and there should be a 3-week time period between the last chemotherapy dose and anticipated delivery, and chemotherapy should not be administered beyond week 33 of gestation (ESMO [Peccatori 2013]).
A long-term observational research study is collecting information about the diagnosis and treatment of cancer during pregnancy. For additional information about the pregnancy and cancer registry or to become a participant, contact Cooper Health (877-635-4499).
CBC with differential, platelet and reticulocyte count (at least every 3 to 4 days); also urinalysis (weekly), liver function test (prior to therapy and weekly), renal function test (prior to therapy and weekly), alkaline phosphatase (weekly). Monitor for infections, CNS toxicity, and gastrointestinal toxicities.
Procarbazine inhibits DNA, RNA, and protein synthesis by inhibiting transmethylation of methionine into transfer RNA; may also damage DNA directly through alkylation.
Absorption: Rapid and complete.
Distribution: Crosses the blood-brain barrier and distributes into CSF.
Metabolism: Primarily hepatic. Oxidized to active metabolites methylazoxy-procarbazine and benzylazoxy-procarbazine, then further metabolized to inactive metabolites (Kintzel 1995).
Half-life elimination: ~1 hour (Perry 2012).
Time to peak, plasma: ≤1 hour (Perry 2012).
Excretion: Urine (70% as inactive metabolites [Kintzel 1995]; <5% as unchanged drug).
