Match each chemotherapeutic agent with its most characteristic adverse effect.

  • DoxorubicinDilated cardiomyopathy
  • BleomycinPulmonary fibrosis
  • CyclophosphamideHemorrhagic cystitis
  • VincristinePeripheral neuropathy

Answer

Doxorubicin pairs with dilated cardiomyopathy. Bleomycin pairs with pulmonary fibrosis. Cyclophosphamide pairs with hemorrhagic cystitis. Vincristine pairs with peripheral neuropathy.
Recognizing the major, predictable adverse effects of standard chemotherapeutic drugs is essential for safe patient management. Each of these agents has a highly specific, classic toxicity profile that guides routine monitoring (e.g., serial echocardiograms for doxorubicin, baseline pulmonary function tests for bleomycin) and implementation of prevention strategies.

Step-by-Step Solution

1
Identify the classic toxicity associated with the anthracycline doxorubicin.
It is strongly associated with dilated cardiomyopathy.
Doxorubicin generates free radicals that cause cumulative, dose-dependent myocardial damage.
2
Identify the classic toxicity associated with bleomycin.
It is strongly associated with pulmonary fibrosis.
Bleomycin causes oxidative damage to the lungs, leading to fibrotic changes and restrictive lung disease.
3
Identify the classic toxicity associated with the alkylating agent cyclophosphamide.
It is strongly associated with hemorrhagic cystitis.
Its toxic metabolite, acrolein, concentrates in the urine and damages the bladder mucosa.
4
Identify the classic toxicity associated with the vinca alkaloid vincristine.
It is strongly associated with peripheral neuropathy.
Vincristine blocks tubulin polymerization, impairing axonal transport in neurons.
