How Side Effects — Are Graded

CTCAE stands for Common Terminology Criteria for Adverse Events. It is a grading system developed by the US National Cancer Institute and used by oncology teams worldwide, including in India. Each side effect — nausea, nerve tingling, fatigue, rash — has its own grade descriptors, but the scale always runs from 1 (mild) to 4 (life-threatening). Your team uses it because it gives a shared, precise language that carries the same meaning between doctors without ambiguity.

Not quite. Grade 1 means you do not need emergency action, but you should still mention it at your next appointment. Patterns matter: a grade 1 fatigue that is present every day and not settling tells your team something different from fatigue that improves between cycles. What your team is watching for is whether the grade stays stable or quietly creeps toward grade 2. Tell them — even if it feels too minor to mention.

Describe it, and let your team grade it. You do not need to pick the number yourself. Tell them what you can and cannot do — whether you can eat a full meal, whether you stayed in bed, whether the discomfort is affecting your sleep. The grade is a clinical judgement your team makes from your description. If you are uncertain whether something is a grade 2 or 3, that uncertainty is itself a reason to call rather than wait.

Possibly paused, not necessarily stopped. A grade 3 typically leads to a dose hold — your next infusion is delayed until the symptom settles back to grade 1 or lower. Whether treatment restarts, at the same dose or a reduced one, depends on what the symptom was and how quickly it resolved. The goal is always to resume treatment when it is safe to do so. Reporting early is what keeps the milder options available to your team.

Yes, the same four grades apply across all side effects — nausea, neuropathy, fatigue, rash, mouth sores, and everything else. What changes is what each grade looks like for that specific symptom. For nausea, grade 1 might mean nausea without vomiting; for fatigue, it might mean tiredness that does not stop normal activities. Your team will explain what grade 2 or 3 looks like for the side effects most likely with your specific treatment, so you know the signs to watch for.

Call the helpline for grade 2 symptoms and for anything grade 3 that is not immediately life-threatening — for example, pain that is not controlled at home, worsening diarrhoea, or a moderate fever. Go directly to the emergency department for grade 4 symptoms: severe difficulty breathing, signs of a serious allergic reaction, confusion, chest pain, or a high fever alongside signs that you are deteriorating rapidly. If you are unsure, call first — your team will tell you which to do.
