Which of the following anticancer drugs can cause hypercoagulable state?
**Core Concept**
The question is testing the student's knowledge of the adverse effects of anticancer drugs, specifically their impact on coagulation pathways. Anticancer drugs can cause a hypercoagulable state by affecting various mechanisms, including the inhibition of anticoagulant proteins, enhancement of thrombin generation, or disruption of normal endothelial cell function.
**Why the Correct Answer is Right**
Certain anticancer drugs, such as L-asparaginase, can lead to a hypercoagulable state by depleting antithrombin levels, a natural anticoagulant protein. This results in an imbalance between procoagulant and anticoagulant factors, increasing the risk of thrombosis. L-asparaginase is an enzyme used in the treatment of acute lymphoblastic leukemia (ALL) and some cases of non-Hodgkin's lymphoma.
**Why Each Wrong Option is Incorrect**
* **Option A:** This drug is not commonly associated with a hypercoagulable state. Instead, it is known for causing other adverse effects, such as myelosuppression and gastrointestinal toxicity.
* **Option B:** This drug is not typically linked with an increased risk of thrombosis. It may cause other side effects, like neuropathy and alopecia, but a hypercoagulable state is not a notable concern.
* **Option D:** This drug can cause various side effects, including myelosuppression and hepatotoxicity, but it is not primarily associated with a hypercoagulable state.
**Clinical Pearl / High-Yield Fact**
When administering L-asparaginase, patients are at an increased risk of thrombotic events, including deep vein thrombosis and pulmonary embolism. Close monitoring of coagulation parameters and prompt treatment of thrombotic events are essential to minimize this risk.
**Correct Answer: C. L-asparaginase. L-asparaginase can lead to a hypercoagulable state by depleting antithrombin levels.**
