Understanding the 3+7 Chemotherapy Protocol
What Is the 3+7 Protocol?
The 3+7 chemotherapy protocol is a standard induction therapy primarily used for treating acute myeloid leukemia. The name "3+7" refers to the treatment schedule: three days of one drug and seven days of another, usually administered together over a specific period. This regimen aims to achieve complete remission by eradicating leukemic cells from the bone marrow and peripheral blood.
Typically, the 3+7 protocol involves:
- Cytarabine (Ara-C): Administered continuously over seven days.
- An anthracycline (such as Daunorubicin or Idarubicin): Given for the first three days.
The combination exploits synergistic effects, maximizing leukemic cell kill while attempting to minimize toxicity.
Components of the 3+7 Chemotherapy Protocol PDF
Key Drugs Used
The core components of the protocol include:
- Cytarabine (Ara-C): An antimetabolite that interferes with DNA synthesis.
- Anthracyclines (Daunorubicin or Idarubicin): Intercalate DNA, inhibit topoisomerase II, and generate free radicals.
Typical Dosing Schedule
A standard 3+7 protocol might look like:
- Day 1-3: Daunorubicin 60 mg/m2 IV daily or Idarubicin 12 mg/m2 IV daily.
- Day 1-7: Cytarabine 100-200 mg/m2 continuous IV infusion daily.
Note: Doses may vary depending on patient factors, institutional protocols, and latest clinical guidelines.
Supportive Care Measures
A comprehensive PDF will also detail supportive measures such as:
- Antimicrobial prophylaxis and treatment for infections.
- Management of cytopenias with transfusions.
- Prevention and management of tumor lysis syndrome.
- Monitoring for cardiotoxicity, especially with anthracyclines.
