Chemotherapy Related Neuropathy: Managing this Nerve Wracking Problem

  1. 1. Chemotherapy Related Neuropathy: Managing this Nerve Wracking Problem Cindy Tofthagen, PhD, ARNP, AOCNP, FAANP University of South Florida University of Massachusetts Boston/Dana-Farber Cancer Institute
  2. 2. Topics of Discussion •What is chemotherapy induced peripheral neuropathy (CIPN)? •What are the risk factors? •What can we do about it?
  3. 3. What is CIPN? A group of neuromuscular symptoms that result from nerve damage caused by drug therapies used in the treatment of cancer. Affects 30-100% of patients getting specific neurotoxic chemotherapy drugs. The most commonly used classes of drugs causing peripheral neuropathy are taxanes (Taxol and Taxotere) and platinum based drugs (cisplatin and oxaliplatin).
  4. 4. •Sensory, motor, or autonomic •Vary from person to person based on type of treatment and individual differences •Numbness, tingling, and discomfort in the upper or lower extremities are the hallmarks of peripheral neuropathy Symptoms
  5. 5. Problem CIPN can last for months to years after chemotherapy and sometimes is permanent. It can interfere with the ability to perform usual activities.
  6. 6. • Increasing dose • Pretreatment or concurrent treatment with other neurotoxic chemotherapies • Diabetes • Hypothyroidism • HIV infection • Charcot-Marie-Tooth disease • Autoimmune disorders • Vitamin B12 deficiency • Chronic alcohol abuse • Shingles
  7. 7. Supposedly chemotherapy increased my chances of living 5 years by 8%. I don’t want to live for another 5 years like this. My hands and fingers are numb. My feet are numb. My legs are numb from my knees to the bottom of my feet. I have pain, gnawing, burning, and cramping most of the time. My legs ache and feel stiff and heavy all the time. Driving is a problem, walking is a problem, Being on my feet is a problem. My hands don’t work. I feel collapsed, dizzy, and weak all day, every day, all the time. I have disabling fatigue. I feel like I have been poisoned. -written in 2008 by Sue, colorectal cancer survivor. (Tofthagen, 2010)

  10. 10. Possible Mechanisms • Oxidative stress • Demyelination • Cytokine mediated inflammation • Sodium ion channel dysfunction • Damage to dorsal root ganglion • Combinations of these • May vary by drug • Genetic factors may influence
  11. 11. 1) Prevent it 2) Recognize it early 3) Control the pain 4) Minimize effects on quality of life
  12. 12. A variety of preventative strategies have been evaluated thus far with varying degrees of success, including:  Calcium/Magnesium Infusions Alpha-lipoic acid B Vitamins Glutamine/glutathione Vitamin E
  13. 13. • Numerous clinical trials supporting its use • One trial was closed because of safety concerns • Recent meta-analysis confirmed safety and efficacy of Calcium and Magnesium infusions for prevention of neuropathy caused by oxaliplatin only • Reduces the incidence of grade 2 but not grade 1 neuropathy (Grothey et al., 2011; Hochster, Grothey, & Childs, 2007; Ishibashi, Okada, Miyazaki, Sano, & Ishida, 2010; Wen et al., 2012)
  14. 14. • Neurotoxicity may be directly related to individual variations in neurotoxic drug metabolism, distribution, and elimination. • Genetic polymorphisms associated with CIPN may lead to genetic tests to help identify individuals likely to develop severe neuropathy Bergmann, et al., 2011; Sissung, et al., 2006; Renbarger, et. al., 2008; Hertz, et al., 2012; Kroetz, et al., 2010; Schneider, et al., 2011.

  16. 16. • Diagnosing and grading of PN is not straightforward • Many different grading scales are available, but no standard method for administering or interpreting these scales has been developed • Available grading scales have many limitations
  17. 17. Nurse’s Self-Assessment of Skills and Practices • 82% recognize CIPN as a significant problem • 75% rate own assessment skills as fair to poor Binner,Ross, & Browner, 2011
  18. 18. Cycle Number Perceived Loss of Balance Fall Risk
  19. 19. What to tell your healthcare team 1. What symptoms are you having? 2. Are the symptoms on one or both sides? 3. How much of the extremity is involved? 4. How severe and distressing is each symptom? 5. Are symptoms constant or do they come and go? 6. How are your activities and lifestyle being affected?

  26. 26. • Pulsed infrared light is delivered to the foot in an effort to improve foot circulation by stimulating nitric acid production • Widely marketed to patients and used by home health agencies • No data to support use for CIPN • No better than sham therapy for diabetic neuropathy (Lavery, Murdoch , Williams , Lavery, 2008)
  27. 27. Treatment of Foot Neuropathy Patients with numbness in the feet should: • wear comfortable, properly fitting shoes • avoid sandals, open toed or open heeled shoes • inspect feet daily for injury • avoid walking barefoot or in socks alone • always check for foreign objects in shoes before putting them on • change shoes in the middle of the day to avoid continued pressure in the same locations (Plummer & Albert, 2008).
  28. 28. Home Safety • Water temperature for bathing should be carefully assesses and the thermostat on the water heater should be adjusted to a maximum of 100 degrees Fahrenheit • run cold water first • use protective gloves when washing dishes • Always use pot holders (Armstrong, Almadrones, & Gilbert, 2005; Hot Water Burns Like Fire Campaign, 2006).
  29. 29. Home Safety • Living areas should be kept well lit • keep walkways clear • nightlights should be kept on in hallways, bathrooms and bedrooms, nonskid mats in the shower or bathtub (Armstrong, Almadrones, & Gilbert, 2005; Visovsky, Collins, Abbott, Aschenbrenner, & Hart, 2007).
  30. 30. Home Safety • store frequently used items in easy-to-reach locations • remove throw rugs and mats • Use sturdy chairs with arm rests • use a long handled reacher to pick up items from the floor • remove clutter around the house • install hand rails in the tub and beside the toilet • use a shower chair and a hand held shower • use hand railing when climbing stairs, • add a strip of brightly colored tape to the steps so that the outline of • each step is clearly visible, • keep walkways and stairs in good repair and free of clutter and debris
  31. 31. Self-Care Techniques • A study of self-reported self care techniques used by patients with related neuropathy (n=450) indicate techniques that patients found helpful in relieving symptoms include: • warm baths (66%) • walking (60%) • massage (41%) • rubbing cream on the feet (47%) • elevating feet (57%) • staying off the feet (59%) • acupuncture (12%) • meditation (20 (Nicholas et al., 2007)
  32. 32. • Compared to healthy people, persons with neuropathy have reduced proprioception, lower extremity sensation, and reduced ankle strength predisposing them to falls • Strength and balance training results in fewer falls • Safe for people with peripheral neuropathy • Tai Chi, a low impact form of Chinese martial art, may help reduce falls and improve balance (Gillespie et al., 2009; Morrison, Colberg, Mariano, Parson, & Vinik, 2010; Allet, et al., 2010; Kruse et al., 2010).
  33. 33. • Neurologist to establish/confirm diagnosis • Pain management • Physiatrist-physician who specialize in cancer rehabilitation, locate one at • Physical therapist -specific exercises designed to help improve muscle strength and balance • Occupational therapists -maintain your independence, adjust to physical limitations • Support groups and mental health professionals • Podiatrists –recommend footwear, and fit for orthotics (Tofthagen, 2012)
  34. 34. Summary • Neuropathy is an uncomfortable and distressing symptom that can interfere with your ability to do the activities you want and need to do on a daily basis. • Scientists are looking for ways to prevent neuropathy caused by chemotherapy. • Patients can get better control of neuropathy symptoms and their effects on quality of life by being aware of treatment options, communicating with their healthcare team and seeking out resources within their community.
