What is Cisplatin?

Cisplatin is a platinum-based chemotherapy drug widely used to treat various types of cancer, including testicular, ovarian, bladder, and lung cancer. It functions by interfering with the DNA replication process in cancer cells, ultimately leading to cell death.

Mechanism of Action

Cisplatin works by forming cross-links in the DNA of cancer cells, preventing their replication and transcription. This disruption triggers a series of cellular responses, including apoptosis (programmed cell death), which is particularly effective against rapidly dividing cancer cells.

Uses of Cisplatin

1. Testicular Cancer: Frequently used as part of combination therapy for advanced cases.

2. Ovarian Cancer: Commonly employed in treating ovarian tumors, often in conjunction with other agents.

3. Bladder Cancer: Used for muscle-invasive bladder cancer and in neoadjuvant therapy.

4. Lung Cancer: Often part of combination regimens for non-small cell lung cancer.

Administration

Cisplatin is typically administered intravenously and is usually given in cycles, allowing for recovery time between treatments. Dosages vary based on the type of cancer and the patient’s overall health.

Side Effects

Common side effects of cisplatin include:

- Nausea and Vomiting: Can be severe but is often manageable with antiemetic medications.

- Kidney Toxicity: Can affect renal function, so hydration and monitoring are essential.

- Hearing Loss: Some patients may experience ototoxicity, leading to hearing issues.

- Bone Marrow Suppression: May lead to decreased blood cell counts, increasing infection risk.

Important Considerations

1. Hydration: Adequate hydration before and after treatment helps reduce kidney toxicity.

2. Pre-medication: Patients may receive antiemetics to prevent nausea and vomiting.

3. Monitoring: Regular blood tests are crucial to assess kidney function and blood cell counts.

4. Drug Interactions: Cisplatin may interact with other medications, so it’s essential to inform healthcare providers of all treatments being taken.
