Study Notes

General Toxicities of Anticancer Drugs

  • Toxic to rapidly dividing normal cells, including bone marrow cells, gut mucosa, skin, hair, gonads, and fetuses
  • Myelosuppression, thrombocytopenia, leukopenia, and suppression of lymphoreticular system leading to increased bleeding, immunosuppression, and opportunistic infections
  • Tumor Lysis Syndrome, causing hyperuricemia, urate nephropathy, and acute kidney injury
  • Hypersensitivity reactions, including rashes, chills, fever, and anaphylaxis
  • Nausea and vomiting due to activation of dopamine, 5-HT3, serotonin, neurokinin-1, and cholecystokinin

Specific Toxicities of Anticancer Drugs

  • Cyclophosphamide: hemorrhagic cystitis
  • Doxorubicin: cardiotoxicity
  • Bleomycin: pulmonary fibrosis
  • Vincristine: neuropathy, syndrome of inappropriate antidiuretic hormone secretion
  • Cisplatin: nephrotoxicity and ototoxicity
  • Methotrexate: hepatotoxicity, nephrotoxicity, and megaloblastic anemia

Minimizing Toxicities of Anticancer Drugs

  • Use of ondansetron to control cytotoxic drug-induced vomiting
  • Platelet and/or granulocyte transfusion after treatment to prevent bleeding or infection
  • Bone marrow transplantation
  • Recombinant colony-stimulating factor to hasten recovery from cytotoxic drug-induced myelosuppression
  • Amifostine to prevent cisplatin-induced nephrotoxicity
  • Vigorous hydration before, during, and after cisplatin infusion to reduce nephrotoxicity
  • Mesna to prevent hemorrhagic cystitis caused by cyclophosphamide and ifosfamide
  • Dexrazoxane to prevent doxorubicin-induced cardiotoxicity
  • Leucovorin to reverse methotrexate toxicity
  • Allopurinol, alkalinization of urine, and plenty of fluids to reduce urate nephropathy

Role of Drug Combinations in Cancer Therapy

  • Enhanced effect by achieving maximal cell killing
  • Broader range of attack on heterogeneous cells
  • Reduced resistance by early/rapid cell kill
  • Reduced toxicity of individual drugs

Principles of Drug Combinations for Cancer Chemotherapy

  • Drug must be active as a single agent against the tumor being treated
  • Combine drugs with different mechanisms of action
  • Avoid combinations with significant toxicity overlap
  • Use intermittent schedule of drug treatment
  • Several cycles of chemotherapy should be given to achieve eradication
  • Adjuvant chemotherapy is given to prevent relapse after surgery or radiotherapy

Drug Combinations for Specific Cancers

  • Acute Myeloid Leukemia: Cytarabine + Daunorubicin (induction), Cytarabine + Daunorubicin/Etoposide (maintenance)
  • Hodgkin’s lymphoma: ABVD regimen (Doxorubicin, Vinblastine, and Dacarbazine), MOPP regimen (Mechlorethamine, Vincristine, Procarbazine, and Prednisone)
  • Non-Hodgkin’s lymphoma: CHOP regimen (Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone)
