Care During Chemotherapy and Beyond
What is Peripheral Neuropathy?
Other terms: peripheral neuropathy, numbness and tingling.
The body's nervous system is divided into two major systems; the central nervous
system and the peripheral nervous system. The peripheral nervous system is
also divided into two major parts, the somatic nervous system and the autonomic
nervous system. The somatic nervous system consists of peripheral nerve
fibers that send sensory information to the central nervous system and motor nerve
fibers that send signals to skeletal muscle. The autonomic nervous system
controls smooth muscle of the viscera (internal organs) and glands.
Peripheral neuropathy results from some type of damage to the peripheral nerves.
Certain chemotherapy drugs can cause peripheral neuropathy such as vinca alkaloids
(vincristine), cisplatin, paclitaxel, and the podophyllotoxins (etoposide and tenoposide).
Other drugs used to treat cancer such as thalidomide and interferon also can cause
Individuals at greatest risk of peripheral neuropathy associated with chemotherapy
are those with preexisting peripheral neuropathy from conditions such as:
- Severe malnutrition
- Previous chemotherapy
Symptoms of Peripheral Neuropathy:
- Numbness, tingling (feeling of pins and needles) of hands and/or feet
- Burning of hands and/or feet
- Numbness around mouth
- Loss of sensation to touch
- Loss of positional sense (knowing where a body part is without looking).
- Weakness and leg cramping or any pain in hands and/or feet
- Difficulty picking things up or buttoning clothes
Areas affected by neuropathy:
- Fingers and toes (most common)
- This may move gradually upward in a stocking-glove type fashion.
- May cause or worsen constipation
- May lead to conditions such as ileus (intestinal blockage).
- Other; face, back, chest.
Although some of the signs of neuropathy may appear suddenly, this change in sensation
usually builds gradually and can worsen with each additional dose of chemotherapy.
It is usually strongest right after a chemo treatment, but tends to lessen just
before the next treatment. The symptoms usually peak about 3-5 months after
the last dose of treatment is taken. The abnormal sensations may disappear
completely, or lessen only partially; they may also involve less of the body.
If neuropathy diminishes, it is a gradual process usually requiring several months.
However, in some cases it may be irreversible and never diminish in intensity or
the area of the body affected.
Things You Can Do to Minimize the Effects of Peripheral Neuropathy:
Various techniques have been tried by patients and recommended by physicians to
prevent, lessen the severity or treat chemotherapy side effects such as
peripheral neuropathy. There is no "one-size-fits-all" regimen
that works for everyone. Much of the treatment is based on trial and error,
and finding what combination of interventions works for the individual.
- Report any unusual feeling you may have to your health care professional.
Let them know if you are experiencing any of the above symptoms, so they can assess.
- Follow instructions regarding rest and delays in treatment.
- Be active in decisions regarding treatment versus quality of life.
Protection and Safety against Peripheral Neuropathy:
- Protect areas where sensation is decreased (example; do not walk around without
foot wear). Wear thick socks and soft soled shoes.
- Extreme temperature changes may worsen symptoms.
- Wear warm clothing in cold weather. Protect feet and hands from extreme cold.
- Use care when washing dishes or taking a bath or shower do not let the water get
- Use potholders when cooking.
- Use gloves when washing dishes, gardening.
- Inspect skin for cuts, abrasions, burns daily, especially arms, legs, toes and fingers.
Simple Comfort Measures:
- Flexible splints
- Lotions and creams
Measures to relieve constipation induced by neuropathy:
- Eat foods high in fiber like fruits (pears, prunes), cereals, and vegetables.
- Drink two to three liters of non-alcoholic fluids (water, juices) each day; unless
you are told otherwise by your doctor.
- Exercise twenty to thirty minutes most days of the week, as tolerated, and if okay
with your doctor. A lot of patients find that walking for exercise is convenient
and easy to do.
- If you have been prescribed a "bowel regimen," make sure you follow it exactly.
Other tips to combat or minimize chemo-based neuropathy:
- Some patients have found techniques such as deep breathing, relaxation and guided
imagery helpful particularly to help with pain associated with neuropathy.
Drugs/Treatment Changes or Therapies That May Be Prescribed:
- Chemotherapy treatments may need to be interrupted or the dose adjusted to prevent
worsening of this side effect.
- Use of vitamins particularly those in the B-complex family.
Control of neuropathic pain:
- Pain relievers (analgesics)
- Antidepressant (such as amitriptyline)
- Antiseizure medications (such as gabapentin)
- Physical therapy may help with strengthening of muscles that are weak. Usual
exercises are range of motion, stretching and massage. Also can recommend
assistive devices such as orthotic braces, canes, and appropriate splints.
- Occupational therapy may also be of help with assistive devices for activities of
- Therapies such as biofeedback, acupuncture, or transcutaneous nerve stimulation
(TENS) may also be recommended/prescribed in severe cases.
When to Contact Your Doctor or Health Care Provider:
- Notify your health care professional if you are experiencing the above symptoms.
- Unrelieved pain.
- Constipation despite laxative use.
