What is the WHO grading standard for chemotherapy side effects?

WHO refers to the World Health Organization. The World Health Organization's grading criteria for chemotherapy adverse effects are typically categorized into five levels: grade 0, grade 1, grade 2, grade 3, and grade 4. A detailed analysis is as follows:

1. Grade 0

The World Health Organization's grading system for chemotherapy adverse effects is commonly used to assess side effects during chemotherapy treatment. The absence of any toxic side effects is classified as grade 0.

2. Grade 1

Mild toxic side effects, which commonly include nausea, vomiting, diarrhea, oral ulcers, hair loss, and skin changes.

3. Grade 2

Moderate toxic side effects, commonly including fever, infection, anemia, edema, gastrointestinal bleeding, and neuropathic pain.

4. Grade 3

Severe toxic side effects; patients may experience serious infections, dehydration, pneumonia, hemorrhage, heart failure, and liver or kidney function impairment.

5. Grade 4

Grade 4 adverse effects can be life-threatening and may lead to severe conditions such as pulmonary infection, toxic encephalopathy, myocardial infarction, cardiac arrest, or liver and kidney failure.

It should be noted that different chemotherapy drugs and treatment regimens may cause varying adverse effects, and individual patients may respond differently to the same chemotherapy drug. Therefore, during chemotherapy treatment, regular physical examinations and monitoring are essential to promptly identify and manage adverse reactions, and treatment plans should be adjusted or modified as necessary based on individual circumstances.
