Immunity, Vaccines, and Cancer Practice Test

Hematologic toxicity refers to effects on blood cell production, typically bone marrow suppression leading to cytopenias. Carmustine is known for causing myelosuppression, which is a true hematologic toxicity. Ototoxicity, on the other hand, affects the ear and hearing and does not involve blood cell production, so it is not a hematologic toxicity. While cardiac, renal, and ocular toxicities can occur with various chemotherapies, they are not hematologic effects either; what matters for this question is that ototoxicity does not involve the blood-forming system, making it the best answer.
