ScienceDaily (Sep. 10, 2008) — Pain is one of the most common symptoms of cancer patients, yet many of them do not receive adequate therapy for the pain caused by their disease or treatments, according to a study in the September 1 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

For cancer patients, pain can come from the cancer itself, chronic inflammatory changes or infections. Standard cancer treatments, such as surgery, chemotherapy and radiotherapy can also cause pain, but despite its common occurrence, pain is a frequent source of patient anxiety due to improper management.

Researchers at the University of Pennsylvania Department of Radiation Oncology in Philadelphia and the Radiation Oncology Branch of the National Cancer Institute in Bethesda, Md., sought to determine the main reasons that patients fail to receive optimal pain therapy.

Between November 2005 and April 2006, 106 radiation therapy patients responded to an Internet-based questionnaire that evaluated their medication use, pain control and attitudes toward pain medication, including prescription and over-the-counter pain medications. Fifty-eight percent reported pain from their cancer treatment and 46 percent of patients reported pain directly from their cancer, yet 80 percent of those patients said that they did not use medication to manage their pain.

Most patients said the main reason they did not take pain medication was because their healthcare provider did not recommend it. This reason was followed by a fear of addiction or dependence and the inability to pay. Some patients also reported using alternative therapies for pain relief, including physical therapy, massage and acupuncture.

“To eliminate barriers to optimal pain management for cancer patients, healthcare providers should talk with their patients about pain symptoms and pain medications,” Charles Simone, M.D., a resident at the National Cancer Institute Radiation Oncology Branch in Bethesda, Md. and lead author of the study, said. “At our institution we have taken these steps by transitioning to an electronic medical record system that has been designed to require an evaluation and documentation of patient pain levels and pain medication responses by healthcare providers at each patient encounter.”

ScienceDaily (Apr. 27, 2007) — A University of Nebraska Medical Center study has found that even before women with breast cancer undergo chemotherapy, they experience fatigue and disruptions in sleep and activity levels. Researchers say their findings suggest health professionals should address fatigue following breast cancer surgery.

Researchers say controlling fatigue after surgery — before starting chemotherapy — is important because fatigue typically increases during chemotherapy. Between 70 to 95 percent of breast cancer patients experience fatigue while undergoing chemotherapy.

The study was published in the current issue of the Journal of Pain and Symptom Management. Having studied 130 women with early stage breast cancer (stage I, II, IIIA), it the largest study to document the prevalence of fatigue associated with altered sleep and activity patterns before chemotherapy treatment. The data confirms what was reported in a previous smaller study funded by the National Institutes of Health.

“We found women are not going into chemotherapy in the best possible shape,” said Ann Berger, Ph.D., Niedfelt Professor of Nursing, UNMC College of Nursing, who has conducted several studies over the past 15 years related to fatigue in cancer patients. “It makes it that much more difficult to reduce the fatigue during treatment. If you start out with some fatigue, it will probably increase.”

“We as health professionals need to address potential fatigue and sleep issues sooner,” said Dr. Berger, principal investigator of the study. “If women are having sleep problems after surgery, we need to address this symptom before women begin chemotherapy. “What we’ve learned might explain why we’re having problems reducing fatigue in breast cancer patients during chemotherapy.”

The published study comes from initial results of a five-year, $1.5 million grant Dr. Berger and her team received in 2003. The purpose of the study, which was funded by the National Institute of Nursing Research, a division of the National Institutes of Health, was to determine the best ways to reduce fatigue during chemotherapy and to prevent chronic fatigue after treatment.

Researchers measured sleep and activity patterns during the 48 hours prior to the first chemotherapy treatment using wristwatch-sized activity monitors called actigraphs.

Fatigue, the most prevalent and distressing symptom for breast cancer patients receiving chemotherapy, has long been accepted by health professionals and patients alike as a side effect of treatment. Researchers say there are ways to intervene, and now they have found it may be important to intervene during the recovery period after breast cancer surgery.

Researchers say disrupted sleep, low daytime activity and/or reduced activity are likely to contribute to mild fatigue before chemotherapy and moderate to severe fatigue after chemo. They say fatigue should be addressed before and after surgery. Women typically begin chemotherapy three to four weeks after surgery.

Dr. Berger said because inactivity contributes to fatigue, she and colleagues say though women need to rest for several days after surgery, they should try to regain activity when they’re able. “We’ve been telling patients for years to rest and take it easy, but in some cases, we’re finding the patients who remain inactive are the one who report higher fatigue.”

Cancer-related fatigue can have a profound impact on an individual’s life, with significant physical, emotional, social, and economic consequences that may persist for months or years after completing treatment. Even after treatment ends, between 30 and 50 percent of patients say their fatigue remains at least six months or doesn’t ever go away.

Fatigue related to cancer treatment is described as a distressing, persistent, sense of tiredness or exhaustion that is not proportional to activity. The factors associated with fatigue are the presence and severity of anxiety, pain, lower sleep quality, physical inactivity, and poor performance status, leaving little desire to work or socialize.

Dr. Berger said the findings provide an important benchmark to begin looking for interventions to reduce cancer-related fatigue.

The study was undertaken to further establish values for sleep, wake, activity, rest, circadian rhythms and fatigue and how they interrelate in women before and during the first year after chemotherapy.

Nervous System Changes

What they are and why they occur

Chemotherapy can cause damage to your nervous system. Many nervous system problems get better within a year of when you finish chemotherapy, but some may last the rest of your life. Symptoms may include:

• Tingling, burning, weakness, or numbness in your hands or feet
• Feeling colder than normal
• Pain when walking
• Weak, sore, tired, or achy muscles
• Being clumsy and losing your balance
• Trouble picking up objects or buttoning your clothes
• Shaking or trembling
• Hearing loss
• Stomach pain, such as constipation or heartburn
• Fatigue
• Confusion and memory problems
• Dizziness
• Depression

Ways to manage

• Let your doctor or nurse know right away if you notice any nervous system changes. It is important to treat these problems as soon as possible.
• Be careful when handling knives, scissors, and other sharp or dangerous objects.
• Avoid falling. Walk slowly, hold onto handrails when using the stairs, and put no-slip bath mats in your bathtub or shower. Make sure there are no area rugs or cords to trip over.
• Always wear sneakers, tennis shoes, or other footwear with rubber soles.
• Check the temperature of your bath water with a thermometer. This will keep you from getting burned by water that is too hot.
• Be extra careful to avoid burning or cutting yourself while cooking.
• Wear gloves when working in the garden, cooking, or washing dishes.
• Rest when you need to.
• Steady yourself when you walk by using a cane or other device.
• Talk to your doctor or nurse if you notice memory problems, feel confused, or are depressed.
• Ask your doctor for pain medicine if you need it.

ScienceDaily (Apr. 18, 2007) — Using Chinese herbs either alone or in conjunction with chemotherapy may help protect a breast cancer patient’s bone marrow and immune system, as well as improving the woman’s overall quality of life.

Sixty per cent of women undergoing chemotherapy for breast cancer experience a range of significant short term side effects. These include nausea, vomiting and fatigue, as well as inflammation of the gut lining, decreased numbers of red and white blood cells and decreased numbers of blood platelets.

Chinese medicinal herbs include mixtures of herbal compounds or extracts from herbs, and they are prescribed to counteract the side effects of chemotherapy. This Cochrane Systematic Review set out to see if there is conventional evidence indicating that these medicines are safe and whether there is evidence that the medicines are effective.

The researchers identified seven randomised studies involving 542 patients with breast cancer. By analysing these data, the researchers concluded that there was no evidence that the Chinese medicinal herbal treatment caused harm, and some evidence that it might reduce side effects.

“Further trials are needed before the effects of traditional Chinese medicines for people with breast cancer can be evaluated with any real confidence,” says Assistant Professor Jing Li, who works at the Chinese Cochrane Centre in Chengdu, China.

Some types of chemotherapy make it harder for your bone marrow to produce new white blood cells. White blood cells help your body fight infection. Therefore, it is important to avoid infections, since chemotherapy decreases the number of your white blood cells.

There are many types of white blood cells. One type is called neutrophil. When your neutrophil count is low, it is called neutropenia. Your doctor or nurse may do blood tests to find out whether you have neutropenia.

It is important to watch for signs of infection when you have neutropenia. Check for fever at least once a day, or as often as your doctor or nurse tells you to. You may find it best to use a digital thermometer. Call your doctor or nurse if your temperature is 100.5°F or higher.

• Your doctor or nurse will check your white blood cell count throughout your treatment. If chemotherapy is likely to make your white blood cell count very low, you may get medicine to raise your white blood cell count and lower your risk of infection.
• Wash your hands often with soap and water. Be sure to wash your hands before cooking and eating, and after you use the bathroom, blow your nose, cough, sneeze, or touch animals. Carry hand sanitizer for times when you are not near soap and water.
• Use sanitizing wipes to clean surfaces and items that you touch. This includes public telephones, ATM machines, doorknobs, and other common items.
• Be gentle and thorough when you wipe yourself after a bowel movement. Instead of toilet paper, use a baby wipe or squirt of water from a spray bottle to clean yourself. Let your doctor or nurse know if your rectal area is sore or bleeds or if you have hemorrhoids.
• Stay away from people who are sick. This includes people with colds, flu, measles, or chicken pox. You also need to stay away from children who just had a “live virus” vaccine for chicken pox or polio. Call your doctor, nurse, or local health department if you have any questions.
• Stay away from crowds. Try not to be around a lot of people. For instance, plan to go shopping or to the movies when the stores and theaters are less crowded.

• Be careful not to cut or nick yourself. Do not cut or tear your nail cuticles. Use an electric shaver instead of a razor. And be extra careful when using scissors, needles, or knives.
• Watch for signs of infection around your catheter. Signs include drainage, redness, swelling, or soreness. Let your doctor or nurse know about any changes you notice near your catheter.
• Maintain good mouth care. Brush your teeth after meals and before you go to bed. Use a very soft toothbrush. You can make the bristles even softer by running hot water over them just before you brush. Use a mouth rinse that does not contain alcohol. Check with your doctor or nurse before going to the dentist.
• Take good care of your skin. Do not squeeze or scratch pimples. Use lotion to soften and heal dry, cracked skin. Dry yourself after a bath or shower by gently patting (not rubbing) your skin.
• Clean cuts right away. Use warm water, soap, and an antiseptic to clean your cuts. Do this every day until your cut has a scab over it.
• Be careful around animals. Do not clean your cat’s litter box, pick up dog waste, or clean bird cages or fish tanks. Be sure to wash your hands after touching pets and other animals.
• Do not get a flu shot or other type of vaccine without first asking your doctor or nurse. Some vaccines contain a live virus, which you should not be exposed to.
• Keep hot foods hot and cold foods cold. Do not leave leftovers sitting out. Put them in the refrigerator as soon as you are done eating.

• Wash raw vegetables and fruits well before eating them.
• Do not eat raw or undercooked fish, seafood, meat, chicken, or eggs. These may have bacteria that can cause infection.

• Do not have food or drinks that are moldy, spoiled, or past the freshness date.
• Call your doctor right away (even on the weekend or in the middle of the night) if you think you have an infection. Be sure you know how to reach your doctor after office hours and on weekends. Call if you have a fever of 100.5°F or higher, or when you have chills or sweats. Do not take aspirin, acetaminophen (such as Tylenol®), ibuprofen products, or any other drugs that reduce fever without first talking with your doctor or nurse. Other signs of infection include:
  • Redness
  • Swelling
  • Rash
  • Chills
  • Cough
  • Earache
  • Headache
  • Stiff neck
  • Bloody or cloudy urine
  • Painful or frequent need to urinate
  • Sinus pain or pressure

What it is and why it occurs

Red blood cells carry oxygen throughout your body. Anemia is when you have too few red blood cells to carry the oxygen your body needs. Your heart works harder when your body does not get enough oxygen. This can make it feel like your heart is pounding or beating very fast. Anemia can also make you feel short of breath, weak, dizzy, faint, or very tired.

Some types of chemotherapy cause anemia because they make it harder for bone marrow to produce new red blood cells.

Ways to manage

• Get plenty of rest. Try to sleep at least 8 hours each night. You might also want to take 1 to 2 short naps (1 hour or less) during the day.
• Limit your activities. This means doing only the activities that are most important to you. For example, you might go to work but not clean the house. Or you might order take-out food instead of cooking dinner.
• Accept help. When your family or friends offer to help, let them. They can help care for your children, pick up groceries, run errands, drive you to doctor’s visits, or do other chores you feel too tired to do.
• Eat a well-balanced diet. Choose a diet that contains all the calories and protein your body needs. Calories will help keep your weight up, and extra protein can help repair tissues that have been harmed by cancer treatment. Talk to your doctor, nurse, or dietitian about the diet that is right for you.

When you get up from lying down, sit for a minute before you stand. Stand up slowly. You may feel dizzy if you stand up too fast.

Your doctor or nurse will check your blood cell count throughout your chemotherapy. You may need a blood transfusion if your red blood cell count falls too low. Your doctor may also prescribe a medicine to boost (speed up) the growth of red blood cells or suggest that you take iron or other vitamins.

Call your doctor or nurse if:

• Your level of fatigue changes or you are not able to do your usual activities
• You feel dizzy or like you are going to faint
• You feel short of breath
• It feels like your heart is pounding or beating very fast
