Which of the following is a cell-cycle-specific chemotherapy agent?

What cumulative dose of doxorubicin is associated with the greatest risk of cardiomyopathy?
Answer: 450–550 mg/m²
Cardiotoxicity from doxorubicin significantly increases when the cumulative dose exceeds 450–550 mg/m².
A patient receiving irinotecan develops profuse diarrhea within 24 hours of infusion. This is best managed with:
Answer: Atropine
Early-onset diarrhea with irinotecan is cholinergic in nature and is treated with atropine.
Which type of radiation therapy delivers a high dose to a small target with steep dose fall-off, minimizing exposure to surrounding tissue?
Answer: Stereotactic radiosurgery (SRS)
Stereotactic radiosurgery (SRS) delivers high-dose, precise radiation to a small target using multiple beams that converge, sparing surrounding tissue.
Which of the following is a common dose-limiting toxicity of cisplatin?
Answer: Nephrotoxicity
Cisplatin causes significant nephrotoxicity; aggressive hydration and amifostine may be used to minimize renal damage.
Hormonal therapy with tamoxifen is most appropriate for which breast cancer receptor profile?
Answer: Estrogen receptor-positive
