Neuropathy as a Side Effect of Melanoma Treatment

Neuropathy (nerve damage causing numbness, tingling, burning, or weakness) can happen during cancer care, including melanoma, but how often it occurs depends on the specific therapy. ^[1] Neuropathy is best known with certain chemotherapies (like platinum agents, taxanes, and vinca alkaloids), is reported with some antibody–drug conjugates and can also arise from immune checkpoint inhibitors as a rare immune‑related side effect. ^{[2] [3]}

What is neuropathy?

• Neuropathy (often “peripheral neuropathy”) typically affects the hands and feet and may feel like pins‑and‑needles, burning pain, or loss of touch. ^[1]
• It can interfere with fine motor tasks (buttoning clothes, holding a pen) and balance or walking when severe. ^[4]

How common is neuropathy in melanoma therapies?

• Chemotherapy: Some drug classes frequently cause neuropathy; risk increases with cumulative dose (for example, taxanes and platinum compounds used in oncology). ^{[5] [6]}
• Immune checkpoint inhibitors (immunotherapy): Neurologic immune‑related side effects, including peripheral neuropathy and Guillain‑Barré–like syndromes, are uncommon overall; severe forms occur in roughly 1–3% of treated patients across cancers, and peripheral neuropathy appears more often reported in people with melanoma compared with some other tumors. [PM13]
• Targeted therapy (BRAF/MEK inhibitors): These agents are more known for ocular and other specific toxicities; neuropathy is not among the most common class effects compared with neurotoxic chemotherapies. [PM15]
• Antibody–drug conjugates and select newer agents: Some are associated with peripheral neuropathy; incidence varies by drug and exposure. ^{[3] [7]}

In practice, neuropathy is relatively common with classic neurotoxic chemotherapies, infrequent with immunotherapy, and not a dominant toxicity with BRAF/MEK targeted therapy. ^[5] [PM13] [PM15]

Typical onset and pattern

• Symptoms often start after several weeks of treatment and can be dose‑related and cumulative, though some drugs can cause symptoms even after the first dose. ^[8]
• Most cases are symmetric sensory symptoms in a “glove and stocking” distribution (fingers/toes, then hands/feet). ^[9]
• Some platinum drugs can show “coasting,” where symptoms worsen for months after therapy stops. ^[6]

When to contact your care team

• Worsening tingling or numbness, pain or burning in fingers/toes, trouble holding small objects, or difficulty walking or feeling the ground are reasons to alert your team promptly. ^[4]

How neuropathy is diagnosed

• Clinicians assess symptom pattern, timing with treatment cycles, and exam findings; they may grade severity and consider tests if immune‑related toxicity is suspected. [PM13]
• Early recognition matters because severe or irreversible neuropathy can require dose changes or stopping the causative drug. ^[10]

Evidence‑based management strategies

Adjusting cancer treatment

• For chemotherapy‑induced neuropathy, teams may reduce dose, delay cycles, or discontinue the offending drug to prevent progression. ^[8]
• With immune‑related neuropathy, treatment typically involves holding immunotherapy and starting corticosteroids or other immunosuppressive care depending on severity, guided by established irAE management approaches. [PM13]

Symptom‑relief medications

• Clinicians often use nerve‑pain agents such as duloxetine, gabapentinoids, or tricyclics to ease discomfort. ^[11]
• Pain plans are individualized and may be combined with topical agents or other supportive measures. ^[2]

Rehabilitation and safety

• Physical therapy can help maintain balance, strength, and function; occupational therapy supports fine motor tasks and home safety modifications. ^[11]
• Strategies like hand/foot cooling during certain infusions have been used to try to lower neuropathy risk with specific chemotherapies, though practices vary by center. ^[12]

Self‑care tips

• Report symptoms early; keeping a diary can help track changes and triggers. ^[10]
• Protect hands and feet (well‑fitting shoes, good skin care), reduce fall risks at home, and consider assistive devices if sensation is reduced. ^[11]
• Some chemotherapy‑related neuropathies may improve over months after treatment ends, while others can persist long term; goals focus on symptom control and function. ^[5]

Examples by drug class

• Platinum compounds (e.g., cisplatin): Dose‑related; may show coasting after therapy ends; symptoms can be reversible with dose modification. ^[6]
• Taxanes (e.g., paclitaxel): Frequency and severity increase with cumulative dose; sensory symptoms are typical. ^[5]
• Vinca alkaloids and several other neurotoxic agents: Notable contributors to neuropathic pain in oncology. ^[2]
• Immune checkpoint inhibitors: Rare but potentially serious neurologic adverse events; tailored evaluation and immunosuppressive management are used. [PM13]

Key takeaways

• Neuropathy can occur with melanoma treatments, but the likelihood varies by therapy: higher with certain chemotherapies, lower with immunotherapy and most targeted agents. ^[5] [PM13] [PM15]
• Early reporting and dose adjustments can prevent progression and disability. ^[8]
• Comprehensive care often combines medication, rehabilitation, and safety strategies to preserve quality of life. ^[11]

Frequently asked questions

Can neuropathy be permanent?

Neuropathy may improve within months after stopping treatment, but some symptoms can linger or remain long term depending on the drug and exposure. ^[5]

Is there anything I can do during treatment to lower risk?

Your team may consider preventive strategies during specific chemotherapies, and staying vigilant about early symptoms helps guide timely dose changes. ^{[12] [8]}

What symptoms should I watch for?

Tingling, numbness, burning pain, weakness, trouble with small objects, or balance issues should be reported. ^[4]
