What is "tumor lysis syndrome"?

• A. A condition leading to increased blood pressure
• B. A life-threatening condition from rapid tumor cell destruction
• C. A type of allergic reaction to chemotherapy
• D. A mild side effect of chemotherapy

Answer: (B)

Tumor lysis syndrome is a life-threatening condition that occurs as a result of rapid destruction of cancer cells, often following chemotherapy. When a large number of tumor cells are killed off quickly, they release their contents into the bloodstream. This sudden release of intracellular components can lead to metabolic complications, including hyperuricemia (high levels of uric acid), hyperkalemia (high levels of potassium), hyperphosphatemia (high levels of phosphate), and hypocalcemia (low levels of calcium). These metabolic disturbances can have serious consequences, such as acute kidney injury, cardiac arrhythmias, and seizures, making prompt recognition and management critical. The syndrome is particularly associated with cancers that have high cell turnover rates, such as acute leukemia and aggressive lymphomas. By understanding tumor lysis syndrome, healthcare providers can take preventive measures, such as aggressive hydration and uric acid-lowering therapies, to mitigate the risks associated with rapid tumor destruction.
