RESEARCH FINDINGS USING GUIDED IMAGERY FOR
People Undergoing Radiation
Scope of the Problem of Radiation Side Effects
The American Cancer Society estimates that more than 1.2 million Americans were diagnosed with cancer in 2001 (2001). More than half of these people received radiation therapy, either alone or in combination with surgery or chemotherapy (Radiation Oncology, 2006). Possible radiation side effects depend on the area of the body treated.
Some of the more common side effects are: loss of appetite; anemia; shortness of breath; fatigue; hair loss; insomnia; nausea and vomiting; skin rash/redness; and diarrhea. In some treatments, there can be painful and unpleasant oral side effects such as cavities, thickening saliva, and taste loss.
Side effects such as hair loss and fatigue can add additional stress to an already stressful disease. The occurrence of side effects, or the fear of having side effects, often leads to patients missing or stopping treatments (Compliance and Compromise, undated).
About 50% of patients don’t follow through with their full treatments, according to the American Cancer Society, and cancer patients often feel a loss of control and feel powerless (Compliance and Compromise, undated). The frequent presence of depression “significantly influence[s]” the severity of fatigue and anxiety in cancer patients (Badger, Braden, and Mishel, 2001).
The majority of patients report significant lifestyle changes. Some have insomnia. Some stop working or work shorter schedules. For others, cancer and its treatment badly affect their household duties and leisure activities (Malone, Harris, et al, 1994). Quality of life is often significantly lessened.
The physical and psychological issues of cancer and radiation can lead to loss of time at work for the patient and/or the caregiver, additional doctor’s office visits, and failure to complete treatment -- all of which contribute to death and disability, and to the $107 billion direct and indirect annual costs of cancer (Healthy People 2010, 2000).
Research in Mind/Body Interventions for Radiation
Patients using guided imagery for coping with radiation therapy reported lower stress levels, more energy, and a better quality of life (Richardson, Post-White, et al, 1997). Patients using audio relaxation and imagery programs reported that they took better care of themselves (Bridge, Benson, et al, 1988). Patients in one study who used radiation-specific guided imagery had “enhanced comfort levels” during treatment, especially in the first three weeks of treatment (Kolcaba and Fox, 1999).
The ability to stay perfectly still is vital during external beam radiation. People using hypnosis have been successful in eliminating unwanted movement (Bertoni, Conardi, et al, 1990), and in coping with claustrophobia during radiation treatments.
Giving patients access to good information (including taped programs for self-help), relaxation training, and Cognitive Behavioral Therapy (CBT) have helped them overcome helplessness and gain a better sense of control (Braden, Mishel, and Longman, 1998; Christman and Cain, 2004; Greer, Moorey, et al, 1992; Johnson, Fieler, et al, 1997). Cognitive Behavioral Stress Management was also effective at lowering cancer patients’ serum cortisol (a stress-related chemical) (Cruess, Antoni, et al, 2000).
The effectiveness of guided imagery, and other mind/body approaches in coping with chronic pain, depression, anxiety, and insomnia have been well documented.
Guided imagery can help patient tolerate radiation therapy, and increase their likelihood of finishing all treatments. It gives patients the tools to improve coping skills, stay relaxed during treatments, and minimize the number and severity of radiation side effects by lowering stress, depression, and anxiety, and promoting a sense of being more in control.
