Skin Toxicity: Side Effects of the Skin
Skin Toxicity, also known as Chemo Rash, is a common side effect for colorectal cancer patients. Certain kinds of cancer treatments, particularly Epidermal Growth Factor Receptor inhibitors, can cause a skin rash and other skin changes for colorectal cancer patients. Skin toxicity can manifest as a skin rash, itching and cracking, fingernail, and toenail irritation, dry skin, and sensitivity to the sun are common side effects.
EGFRs are located on cells and receive signals that let them know when it’s time for the cell to grow and divide. According to the National Cancer Institute, when this receptor is mutated, this can cause cancer cells to divide more rapidly. EGFR inhibitors are a class of targeted therapy drugs that block these receptors from receiving signals to grow, and thus slowing cancer cell growth.
Since the epidermis (outer layer of skin), hair follicles, and oil-producing glands have more EGFRs than other organs, the unintended consequence of EGFR-i drugs can include skin toxicity (AKA chemo rash, skin rash, and EGFR rash). Other treatments, specifically multikinase inhibitors (like regorafinib), can lead to another type of skin reaction called hand-foot skin reaction (HFSR). Some chemotherapies, like 5-FU, can lead to an additional side effect of the skin called hand-foot syndrome.

Symptoms of Skin Toxicity (Chemo Rash)
Skin toxicity can manifest in several ways:
- Itchy skin
- Pimple-like bumps on face, neck, and chest

- Changes in hair texture and curling of the eyelashes and eyebrows
- Dry, flaky skin on face, neck, and scalp

- Brittle nails, nails that become loose in the nail bed
- Sores in and around the nose and mouth
Symptoms of Hand-Foot Skin Reaction (HFSR)
- Numbness, burning, tingling, or “pins and needles” feelings in hands and/or feet
- Increased sensitivity or sensitivity to hot objects
- Redness and/or swelling of hands and/or feet
- Hard layers of skin forming on the palms of hands or bottoms of feet, blisters, dry or cracked skin, or flaking or peeling skin
Tell your treatment team as soon as possible if you have signs of HFSR. Your team can help to determine the severity of your symptoms and can help you manage them by adjusting your treatment dose.
