Chemotherapy-Induced Peripheral Neuropathy: Symptoms, Causes, Treatment
اعتلال الأعصاب الناجم عن العلاج الكيميائي
Chemotherapy-induced peripheral neuropathy is nerve injury that may cause numbness, pain, weakness or imbalance. Early reporting helps the team protect function and adjust supportive care.
What is Chemotherapy-Induced Peripheral Neuropathy?
It can emerge during treatment or persist afterward, with risk varying by medicine. Some symptoms improve gradually while others remain; recovery is not guaranteed when treatment ends.

Symptoms
Tingling, burning or numb hands and feet may accompany difficulty fastening buttons, walking or sensing temperature. Standing dizziness or constipation can occur depending on affected nerves.
Causes
Platinum drugs, taxanes and other anticancer agents can damage nerve fibers. Diabetes, nutritional deficiency or pre-existing neuropathy can overlap and should be evaluated.
Risk factors
Drug type, cumulative dose, existing neuropathy, diabetes and individual factors influence risk. Evaluate symptoms rather than assuming every numb sensation is an inevitable chemotherapy effect.
Diagnosis
Assessment reviews pattern, timing and functional impact and examines sensation, strength and reflexes. Laboratory or nerve tests are selected when necessary rather than required for every patient.
Treatment
The oncology team may adjust dose or schedule after balancing toxicity and treatment benefit. Duloxetine can help selected painful cases; rehabilitation supports function, and evidence differs across medicines and supplements.
Complications
Walking, driving and fine movements can be affected, with increased falls, burns and persistent pain. Ongoing support may address balance, work, sleep and quality of life.
Prevention
Inspect feet, protect skin from burns and cuts and remove trip hazards. Do not use limb cooling or supplements for prevention without team advice or stop cancer treatment independently.
When to see a doctor
Report new or worsening numbness before the next dose. Rapid weakness, repeated falls, swallowing or breathing difficulty or sudden one-sided changes needs urgent assessment.
