How common is mouth ulcers with cisplatin tx

Let me help explain mouth ulcers (also called oral mucositis) during cisplatin treatment for colorectal cancer.

According to the NCCN Guidelines for Supportive Care (2023), oral mucositis is a very common side effect of chemotherapy treatments like cisplatin. The guidelines indicate that approximately 40% of patients receiving standard chemotherapy may experience some degree of mouth sores or ulcers.

The American Cancer Society notes that mouth sores typically:

• Begin about 5-10 days after starting chemotherapy
• Can range from mild to severe
• Usually heal within a few weeks after treatment ends
• Are more common when cisplatin is combined with other chemotherapy drugs

ASCO Guidelines for Management of Oral Mucositis (2023) recommend several preventive measures:

1. Good oral hygiene
2. Regular mouth rinses with salt water or baking soda
3. Avoiding spicy, acidic, or rough foods
4. Using a soft toothbrush

Important: If you develop mouth sores, always tell your healthcare team as they can:

• Prescribe medications to help manage pain
• Adjust treatment if needed
• Monitor for potential infections
