64 Seminars in Oncology Nursing, Vol 28, No 1 (February), 2012: pp 64-74 TRADITIONAL CHINESE MEDICINE FOR CANCER-RELATED SYMPTOMS MARY ELIZABETH SMITH AND SUSAN BAUER-WU OBJECTIVE: To familiarize oncology nurses about the theory and research related to Traditional Chinese Medicine (TCM) for management of cancerrelated symptoms. DATA SOURCES: Peer-reviewed journal articles, TCM texts, professional experience. CONCLUSION: The increasing integration of TCM into mainstream medicine mandates that oncology professionals be familiar with the benefits as well as risks. Clinical research on acupuncture in cancer care is growing and demonstrates it is safe for cancer patients, although results on efficacy across symptoms have been mixed. IMPLICATIONS FOR NURSING PRACTICE: Informed oncology nurses can assist patients by making appropriate referrals to licensed acupuncturists and qualified TCM practitioners to help alleviate unpleasant symptoms associated with cancer and conventional cancer treatment. KEY WORDS: Acupuncture, Traditional Chinese Medicine, cancer, Qi RADITIONAL Chinese Medicine (TCM) is based on the understanding that the body has an innate intelligence and healing ability. It is a whole system of medicine that integrates many therapies and is applied by practitioners to prevent and treat illness or disease. It uses acupuncture and herbal T medicine to help balance and regulate the flow of ‘‘Qi,’’ a person’s vital energy force, therefore enhancing the body’s healing process.1 In this medical system, illness is caused because of an improper flow of this vital energy force. With its 2,500 to 5,000 year tradition of use, TCM is one of the oldest, continuously used Mary Elizabeth Smith, RN, DOM: Director of Chinese Medicine Services, UNM Center for Life, University of New Mexico, Department of Internal Medicine, Albuquerque, NM.

In China, it has been used as the primary health care system for thousands of years and most recently has been used in combination with Western medicine to treat a variety of conditions. TCM consists of six primary branches that offer a holistic approach to lifestyle and health care: 1) acupuncture, 2) herbal medicine, 3) massage (tuina), 4) exercise (Tai Chi, taiji, Qigong), 5) dietary therapy, and 6) lifestyle modifications.1 Growing evidence shows that TCM can be used safely and as a helpful adjunct to conventional care in the treatment of cancer-related symptoms. This article will provide an overview of the theory guiding TCM, describe research of TCM for cancer-related symptoms focusing on three branches of TCM (acupuncture, Chinese herbal medicine, and exercise [Tai Chi]), provide an example of a TCM practitioner’s case example, and describe practical suggestions for oncology nurses related to TCM practitioner qualifications, cost, and insurance coverage. COMPARISON OF TCM AND CONVENTIONAL MEDICINE There are several factors that distinguish TCM from conventional medicine. TCM focuses on a global holistic view of a person. It encompasses the physical, emotional, social, and spiritual aspects that can influence health and illness. In TCM, signs and symptoms are pieced together to form a ‘‘pattern of disharmony’’ within the entire human body. This process takes into consideration the whole pattern presented by the patient, giving equal importance to the body, emotions, mind, and spirit. Conventional medicine has the ability to view and treat each system of the human body with intense focus and accuracy. TCM synthesizes a number of factors that lead to imbalance: internal factors such as stress, nutritional, emotional, sexual, and lifestyle factors, as well as external factors relating to the daily external environment including wind, dampness, heat, dryness, and cold.1 If the person is able to maintain a state of internal balance, they are less likely to contract illness or pain from either internal or external factors. TCM puts a premium on assisting the body to achieve and maintain this balance. In conventional medicine, illness, disease and symptoms are often treated pharmacologically or surgically. The combination of both approaches often provides optimal results. 65 Treatment with TCM is not disease-oriented, but strategy-oriented based on the underlying cause. The cause is determined by accompanying signs and symptoms, strength of the patient, strength of any pathogenic influence, root and secondary symptoms, location of pain (in terms of body organs and channels affected) and whether the symptom is acute or chronic.1 BASIC CONCEPTS OF TCM Yin and Yang The principle of yin and yang is one of the most important concepts in TCM. Yin and yang express polar complements that exist in relationship to each other and represent essential parts of a whole. Neither yin nor yang can exist without the other. Each supports the other and depends on the other for existence. Everything in the cosmos has both yin and yang aspects in constant motion. The Taiji symbol or the great polarity is balanced black and white. The black represents yin and the white represents yang. Yang always includes a seed of yin and yin always includes a seed of yang. In a pain-free healthy body, yin and yang are balanced and in harmony. Because of the everchanging influence of internal and external factors, the balance of yin and yang can shift. The treatment goal is to restore the equilibrium of yin and yang. According to TCM, health results from maintaining balance within the interior of the body and the external environment and lifestyle factors such as diet, exercise, sexual activity, habits, accident, trauma, and epidemic. In this paradigm, disease, including cancer, is caused by an imbalance between the body and the environment or within the internal landscape of the body (which can also be genetic). TCM puts more importance on maintaining this balance so that the body can naturally resist disease rather than killing microorganisms that can make us ill. The basic causes of disease can be internal or external. External factors include climatic conditions of wind, cold, heat, summer heat, dampness, and dryness. Internal factors include the emotional landscape within a person. TCM focuses on seven primary emotions that affect us: fear (normal and adaptive human emotion), anger, joy, worry, sadness, grief, and fright. Disease caused by emotions often becomes chronic, injuring the organs, Qi, and blood.1 66 M.E. SMITH AND S. BAUER-WU Pain, for example, can be associated with the internal organs. The yin organs are the solid organs that include the heart, liver, spleen, lung, kidney, and pericardium. Their main function is the manufacturing and storing of the vital essence: Qi, blood, and body fluid. The yang organs are the hollow organs. They receive and digest food, absorb nutrition, and dispose of waste. The yang organs include the small intestine, gall bladder, stomach, large intestine, urinary bladder, and an extra organ system called the ‘‘triple burner.’’1 The yin organs and the yang organs work together as a unit. They are considered functional complexes rather than just anatomical structures. These organs systems transform and cycle in five phases known as Wu Xing. Wu Xing: The Five Phases of Transformation The five phases of transformation, Wu Xing, describes a cycle by which transformation happens in the human body. The five phases are: water, wood, fire, earth, and metal.1 Each phase corresponds to particular structures and functions in the body, as well as emotions, spiritual qualities, tissues, and life stages. Each stage also has a particular connection with aspects of the external world such as a season of the year, climate, directions, color, and taste. The Channels or Meridians Channels or meridians carry blood and Qi through the body via an invisible network that links fundamental structures, functions, and organs of the body. Channel theory states that a disorder within a particular channel affects the course of the channel and the organ system associated with it.1 A disharmony in the organ likewise affects the associated channel. For example, a disharmony in the urinary bladder may manifest in symptoms along the urinary bladder channel, such as pain in the back. The channels are regarded as 3-dimensional passageways through which the Qi and blood flow at different levels of the body. The channels are bilateral. There are 14 major channels, each containing a number of independent points, 12 of which correspond to the major yin-yang organs of the body. These channels have continuous, interlinking patterns of circulation. The two additional major channels, the Conception Vessel (along the front midline of the body) and the Governing Channel (along the backside of the body) are part of the system of eight extra channels. The eight extra channels do not fit the pattern of the major channels. Rather, they serve as reservoirs, filling and emptying in response to the varying conditions of the major channels and exerting a regulating effect on them. Qi and Blood Qi is the essence of everything in the universe. It is the vital energy force in the human body. Without it, there would be no existence, no life. According to TCM, all things that exist, living and nonliving, have Qi.1 Qi is considered yang (as compared with blood) and is associated with function, activity, and movement. In this system, blood is more than the red fluid that runs through our veins. Its primary function is to circulate through the blood vessels and channels to nourish, maintain, and moisten the body, while promoting the functional activities of the organ systems and tissues.1 Qi and blood are one of the most primary yinyang polarities in the human body. Qi (yang) is necessary to move the blood. According to TCM, blood (yin) is made from the Qi of food. Blood nourishes the organs that produce and regulate Qi. Clinically, a deficiency of Qi often leads to a deficiency of blood and vice versa. Disharmonies of blood (such as in blood cancers) can lead to deficient blood and/or stagnant blood. Both Qi and blood deficiency/stagnation can cause pain.1 Diagnosing imbalances. Chinese medical patterns of cancer have three specific diagnostic similarities for the majority of cancer patients.1 These patterns are noted in stages. Stage 1 – A yin-yang imbalance develops in the body and usually involves several organ systems. Stage 2 – As the imbalance worsens, Qi and blood are depleted and begin to stagnate. Stage 3 – The communication and cooperation among the organs (as related in the fiveelement cycle) deteriorates, the immune response becomes impeded, the endocrine system malfunctions, and the adaptive qualities of the body deteriorate. Diagnosing the imbalance or pattern of disharmony is key to encouraging health and healing as well as identifying the stage. There are specific diagnostic tools used in TCM.1 A diagnosis is made by observing, listening, smelling, palpating, and asking the patient about TRADITIONAL CHINESE MEDICINE FOR CANCER-RELATED SYMPTOMS all symptoms including emotions, onset of symptoms, time of day or year that symptoms become worse, and medical history. Specific questions will provide information on: what improves or worsens the pain, chills, fever, perspiration, eating and drinking, appetite, taste, bowel movements, urination, pain location and quality, sleep, sexual function/desire, and menstruation. These questions assist in acquiring the whole picture of the pattern of disharmony. An additional palpation tool in TCM is pulse diagnosis. A rapid pulse typically means heat, slow pulse means cold, strong pulse means excess, weak pulse means deficiency, and floating pulse means external condition such as cold or flu. Tongue diagnosis is a tool used by the practitioner to observe the shape, color, and condition of the tongue body and coating. A healthy tongue has no restrictions in movement, is light pink in color, thin white coat, without being overly dry or wet, and is not swollen or too thin. An unhealthy tongue would be a deviation from the healthy tongue. Some basic tongue diagnosis are red tongue body ¼ heat; yellow tongue coating ¼ heat; pale tongue body ¼ cold and deficiency; white tongue coating ¼ normal or cold; purplish tongue body ¼ stagnation of Qi and/or blood; and a thick or sticky tongue coating ¼ dampness, phlegm, or food stagnation.1 Acupuncture Acupuncture is a branch of TCM that modulates neurological processes to bring about its effects.2,3 Acupuncture is a technique in which very tiny needles of varying lengths are inserted through the skin in specific locations called acupoints. To restore balance and a healthy energy flow to the body, needles are inserted into acupoints and left in place for less than half an hour. The practitioner may apply heat or a weak electrical current (electro-acupuncture) to enhance the effects of the therapy. Auricular acupuncture is a method of acupuncture that involves stimulating points on the ear to obtain relieving benefits. Moxibustion may also be used in conjunction with acupuncture. It uses the heat generated by burning herbal preparations containing Artemisa vulgaris to stimulate acupuncture points,1 and is helpful in reducing side effects from chemotherapy.4 Additionally, acupressure may be used in place of acupuncture, particularly because patients can do it themselves. Acupressure works similarly to acupuncture; however rather than needles, 67 finger-point pressure is placed on acupoints. In general, acupuncture is well tolerated and significant adverse effects are rare.5-8 Research on the use of acupuncture for management and prevention of cancer symptoms is increasing. To date, studies have addressed the safety and effectiveness of acupuncture for cancer-related pain, hot flashes, nausea and vomiting, xerostomia, lymphedema, as well as other symptoms. See Table 1. Pain. A number of studies have evaluated the effectiveness of acupuncture on cancer-related pain.9-14 In a recent Cochrane Review paper on this topic,11 three randomized controlled trials (RCTs) were identified and included in the analysis. While all three studies revealed lower selfreported pain during and up to 2 months after acupuncture treatments, the authors concluded that there is insufficient evidence and results need to be viewed with caution because of methodologic limitations. In one of the studies Alimi et al10 conducted a randomized, blinded, controlled trial of auricular (ear) acupuncture in cancer patients experiencing neuropathic pain (N ¼ 90). Three groups were assessed, one treatment (acupuncture, n ¼ 29) and two control (placebo auricular acupuncture, n ¼ 30 and placebo auricular seeds, n ¼ 31), at baseline (before the 1-month intervention period) and 30 and 60 days later. Using a visual analog score (VAS), they noted that pain intensity significantly decreased in the acupuncture group at day 30 (P ¼ .02) and day 60 (P <.001) compared with both of the placebo groups. Similarly, positive findings were also demonstrated in a small, uncontrolled pilot study with cancer patients experiencing pain caused by bone metastasis (N ¼ 5).14 Paley and Johnson14 found that a single acupuncture treatment reduced mean pain scores from 4.3 (on a numerical rating scale) before treatment to 0.8 immediately after, which increased to 3.2 at 48 hours after the acupuncture treatment. In contrast, Deng et al9 failed to show any difference in reducing pain after cancer surgery between a special acupuncture technique (delivered preoperatively with implanted needles that were retained for 4weeks) and sham (placebo) acupuncture in a well-designed study of cancer patients undergoing thoracotomy (N ¼ 162). In summary, several studies have been conducted on acupuncture for cancer-related pain with mixed results. Many of the studies are methodologically flawed. Research to date has used 68 M.E. SMITH AND S. BAUER-WU TABLE 1. Summary of Research on Acupuncture for Different Cancer-Related Symptoms Symptom Substantiality of Evidence Summary of Findings and Comments Pain Several studies including some with high-quality designs Nausea and vomiting Several studies including some with high-quality designs Hot flashes Xerostomia Several studies with both breast and prostate cancer patients. More high-quality studies done with breast cancer patients A few studies including some RCT Mixed. Some studies demonstrate reduction in pain after acupuncture and some do not. Different acupuncture techniques used. Different types of cancer pain evaluated Mixed. Traditional acupuncture appears to be helpful in alleviating acute vomiting and acupressure helpful for acute nausea. Acupuncture does not seem to be any more effective than sham in preventing or controlling delayed nausea and vomiting Generally positive in both breast and prostate cancer patients Lymphedema Two small pilot studies Other: General health-related quality of life, anxiety, depressed mood, sleep, and fatigue Small and/or uncontrolled different acupuncture techniques and included patients with different types of cancer-related pain. Therefore, it is difficult to draw conclusions on the benefits of acupuncture for cancer patients experiencing pain. Nausea and vomiting. A fairly substantial evidence base exists on the use of acupuncture for chemotherapy-induced nausea and vomiting. In a Cochrane Review report15 consisting of 11 studies compiled until 2006, differential effects were found depending on the technique and the specific symptom (ie, nausea vs. vomiting, acute vs. delayed). In this meta-analysis including a total of 1,247 cancer patients, they found electroacupuncture to be effective for reducing the incidence of acute emesis, but not severity of acute emesis or delayed nausea. They also found that acupressure reduced acute nausea, but not delayed nausea or acute or delayed emesis. Furthermore, they determined that noninvasive electrostimulation was not effective for either nausea or vomiting. Regarding the use of acupuncture for radiation-induced nausea, Enblom et al16 conducted a large RCT of cancer patients receiving Promising for electroacupuncture, although studies have had small sample sizes Promising findings, although uncontrolled studies with very small sample sizes Promising findings for mood, arthralgias, sleep, and neuropathy. Studies are limited by methodologic flaws and small sample sizes abdominal/pelvic irradiation. Participants were randomized to either acupuncture (n ¼ 109) or sham (n ¼ 106), for which they received two to three treatments each week during radiation therapy. Acupuncture was found to be no more effective than sham in reducing incidence of radiation-induced nausea. In summary, acupuncture and acupressure are associated with diminished chemotherapy-induced acute vomiting and acute nausea, respectively, across a number of studies, but no effect was found on radiationinduced nausea in one well-designed study. Hot flashes. Several studies have assessed the effects of acupuncture in reducing cancer treatment-related hot flashes in both women with breast cancer and men with prostate cancer. Walker et al17 conducted an impressive RCT, comparing acupuncture with venlafaxine in hormone receptor-positive breast cancer patients (N ¼ 50, 25 per group). After 12 weeks of treatment, both groups had significant improvements as measured by reduced hot flashes and depressive symptoms and enhanced quality of life. Two weeks after the treatments were completed, the TRADITIONAL CHINESE MEDICINE FOR CANCER-RELATED SYMPTOMS venlafaxine group had significant increase in hot flashes, which was not observed in the acupuncture group. The medication was also associated with 18 incidences of adverse effects, while none for acupuncture. Frisk et al18 conducted a similarly designed study with breast cancer survivors, comparing acupuncture with HRT. Forty-five women were randomized to either acupuncture for 12 weeks or HRT for 24 months. (Note that this study was conducted when HRT was an acceptable treatment, which it is not now.) Both groups demonstrated improvements with reduced number of and distress from hot flashes and increased number of hours slept and levels of general well-being after the intervention periods, although the acupuncture group did not demonstrate as large decrease in the number of hot flashes as the comparison group. In another RCT, Deng et al19 assessed hot flash frequency in women with breast cancer experiencing three or more hot flashes per day (N ¼ 72). They were randomly assigned to receive either true or sham acupuncture, both delivered twice weekly for 4 consecutive weeks; those assigned to the sham group were crossed over to receive true acupuncture beginning at week 7. Number of hot flashes was evaluated at baseline, at 6 weeks, and after 6 months. At 6 weeks, both groups had reduced frequency of hot flashes, with the true acupuncture group decreasing from 8.7 (standard deviation [SD], 3.9) to 6.2 (SD, 4.2) and the sham group from 10.0 (SD, 6.1) to 7.6 (SD, 5.7), which was not statistically significant. After the sham acupuncture participants were crossed over to true acupuncture, further reductions were observed. Both groups demonstrated persistent reduction in the number of hot flashes for up to 6 months after the completion of true acupuncture treatment. Finally, in breast cancer patients (N ¼ 50) experiencing hot flashes while on treatment with tamoxifen, a single-arm, pre-post study found a 49.8% decrease in the mean frequency of hot flashes and improvements in health-related quality-of-life symptoms from baseline to end of eight acupuncture treatments.20 Regarding men with prostate cancer, a systematic review identified six studies evaluating acupuncture for treatment of hot flashes.21 Of these, five were observational and one was an RCT. The uncontrolled studies identified consistent improvements in the number and severity of hot flashes; however, all of these studies have notable methodologic limitations. In the one 69 RCT, Frisk et al22 compared 12 weeks of electroacupuncture with traditional acupuncture (N ¼ 29) and found statistically significant within-group differences from baseline to end of treatment, from a median of 7.6 to 4.1 in the electroacupuncture group (P ¼ .012) and 5.7 to 3.4 in the traditional acupuncture group (P ¼ .001). Distress decreased in both groups. Both groups demonstrated lasting effects up to 9 months after completion of treatment and minimal side effects. In summary, evidence to date demonstrates positive effects of acupuncture in the treatment of hot flashes in men with prostate cancer. Xerostomia. Studies have investigated the effectiveness of acupuncture in the alleviation of dry mouth and dysfunction in head and neck cancer patients treated with radiation therapy. O’Sullivan and Higginson5 conducted a systematic review on this topic and identified three RCTs, two comparing true acupuncture to sham acupuncture and one compared with usual clinical care. While all three of these trials demonstrated benefits, authors of the systematic review noted that evidence is too limited to draw conclusions. Pfister et al23 conducted a RCT comparing acupuncture (weekly for 4 weeks) to usual care over the same period of time. Fifty-eight patients with head and neck cancer (28 in acupuncture group and 30 in control group) completed selfreport measures of xerostomia and a composite measure of pain, function, and activities of daily living (called the Constant-Murley score). They found significant improvements in the acupuncture group compared with control for xerostomia (P ¼ .02) and the composite score (P ¼ .008). Another randomized, controlled study evaluated the effects of preventive acupuncture during radiation therapy for patients with head and neck cancer and found significant improvements in biological salivary flow (P <.001) and self-reported and dry mouth (P <.05) in patients who received acupuncture compared with controls.24 Additionally, one study tested ‘‘acupuncture-like transcutaneous electrical nerve stimulation’’ (ALTENS) delivered daily throughout the course of radiotherapy. They measured saliva production and subjective ratings of dry mouth in 56 head and neck cancer patients (30 intervention, 26 usual care control) and found no differences between groups at 3 months after completion of treatment. While the number and methods of studies are limited, true acupuncture seems to be a promising 70 M.E. SMITH AND S. BAUER-WU treatment for radiation-induced xerostomia in patients with head and neck cancer. The one study of a noninvasive, ‘‘acupuncture-like’’ treatment suggests that is not a beneficial approach. Lymphedema. Two small studies have been identified on the use of acupuncture for management of lymphedema. Cassileth et al25 evaluated the safety and feasibility of acupuncture in nine women with chronic lymphedema after breast cancer surgery. All participants received acupuncture twice weekly for 4 weeks. They found that 44% (4/9) of the women had >30% reduction in size difference affected and unaffected arms at 4 weeks compared with baseline, and no serious adverse effects. The other study, by de Valois et al,26 used mixed methods to evaluate effectiveness of acupuncture (seven weekly individualized treatments and six optional) in breast (n ¼ 37) and head and neck cancer (n ¼ 8) patients. The main study variable was an instrument called ‘‘Measure Yourself Medical Outcome Profile’’ (MYMOP), whereby participants identify and rate their most troublesome symptoms. Significant improvements (P <.0001) in MYMOP were identified after the acupuncture treatment periods in both breast and head and neck cancer patients, and in function (SF-36) in breast cancer only at 4 weeks after, not at 12 weeks. In summary, research on acupuncture for lymphedema is extremely limited. Two pilot studies had promising results that warrant additional research in this area. General symptoms and health-related quality of life. Studies have addressed the effects of acupuncture on other cancer-related symptoms, such as mood, arthralgias, neuropathy, sleep, and fatigue. Feng et al27 conducted an RCT of acupuncture (n ¼ 40) versus the antidepressant medication fluoxetine (n ¼ 40) using validated instruments for self-reported depressive symptoms and sleep. They found that the acupuncture group had significantly lower depressed mood (P <.05) and better sleep quality (P <.01) after treatment compared with the group receiving the antidepressant medication. A well-designed (randomized and blinded) study compared true acupuncture with sham intervention for treatment of arthralgias for postmenopausal breast cancer patients receiving aromatase inhibitors.28 After 6 weeks of treatment (twice each week), significant differences in joint pain-related scores were observed across all measures with greater improvements in the acupuncture group compared with sham, such as lower worst pain scores (P <.001), and lesser pain severity (P ¼ .003) and pain-related interference (P ¼ .002). In a small, single-arm pilot study with 18 patients with mixed cancer diagnoses, acupuncture was associated with improvements in peripheral neuropathy and self-reported sleep and decreased analgesia use.29 In a small, uncontrolled pilot study, patients with advanced ovarian and breast cancer had statistically and clinically significant improvements in anxiety, fatigue, pain, depression, and life satisfaction after 8 weeks of acupuncture treatments (12 treatments given over 8 weeks), which were sustained at 12 weeks.30 In summary, the small studies have explored acupuncture for other cancer-related symptoms, and have identified promising findings in selfreport measures. Chinese Herbal Medicine Chinese herbal medicine focuses on restoring the balance of energy, body, and spirit to maintain health rather than treating the cancer itself. Herbs are used to restore balance by changing abnormal patterns and by nourishing the body.1 Herbal medicine treats the underlying disharmony as well as patterns and symptoms and is often used along with conventional cancer treatments. There are a variety of methods of administering TCM herbal treatments, including oral administration, topical/external application (particularly for pain), intravenous infusion, and inhalation.1,31 Because of the variety and combination of herbs used in Chinese herbal medicine, and shared mechanisms with prescribed drugs, there is a potential for negative interactions such as increased toxicity or diminished treatment effects.32 Chinese herbal medicine for treatment of cancer-related symptoms has been studied fairly extensively, with most studies focusing on pain. In a systematic review paper of 115 studies, 41 were RCTs that compared Chinese herbal medicine with conventional analgesics or placebo controls.31 Conclusions drawn from this extensive review indicate the following: Chinese herbs are effective in treating cancer pain, similar to traditional analgesic medications; Chinese herbal medicine has lesser side effects than conventional pain medicines; various methods (topical, oral, and intravenous) are all acceptable modes of delivery of Chinese herbs for treatment of cancer pain. While there are many studies included in this TRADITIONAL CHINESE MEDICINE FOR CANCER-RELATED SYMPTOMS review, the authors note that quality of the studies varied greatly, with some studies having methodologic limitations or lacking sufficient information to adequately judge. Furthermore, in another extensive review paper of preclinical and clinical studies, Chinese herbs were found to be effective in improving a number of side effects associated with chemotherapy and radiation therapy, including diarrhea, poor appetite, and radiationinduced pneumonitis.33 Finally, a large RCT of 2,466 cancer patients experiencing pain evaluated three study groups: 1) traditional Taiwanese herbal diet for pain (consisting of analgesic herbs [paeony root and licorice root] plus vegetable soup); 2) reference group (usual diet control); and 3) comparison group without herbs (vegetable soup). After 1 week on the respective diets, the herbal diet intervention group had significantly lower levels of pain compared with the two control groups (P <.05).34 These data support the use of Chinese herbal medicine for the management of cancer symptoms, especially pain. Tai Chi Tai Chi Chuan (Tai Chi) is a Chinese system of exercise characterized by a series of very slow and deliberate balletic body movements that enhance the flow of vital energy force.1 It was designed for self-defense, exercise, and meditation and is usually practiced in group settings. Growing evidence across clinical conditions demonstrates benefits of Tai Chi.35 However, studies with cancer patients are limited. Mustian et al36,37 conducted a RCT of breast cancer survivors who were randomized to either Tai Chi or psychosocial support (control group); both study arms had three 60-minute group sessions each week for 12 consecutive weeks. The Tai Chi group had improvements in self-esteem as well as healthrelated quality of life while the control group declined.36 Physiological measures of functional and aerobic capacities and muscular strength also improved in the Tai Chi participants and declined in the controls, while both groups had improved flexibility.37 In a small, single-arm feasibility study of a 6-month Tai Chi self-help education for gastric cancer survivors (N ¼ 21), there were no measurable differences between pre- and postintervention scores of depression and quality of life.38 Two systematic reviews on Tai Chi for cancer patients39,40 found benefit of Tai Chi in controlling psychological and physical symptoms. However, meta-analysis of three RCTs of women with breast 71 cancer revealed no significant effects of Tai Chi compared with controls.40 The authors conclude that the evidence is not strong enough to draw reasonable conclusions as to the effectiveness of Tai Chi in cancer patients.39,40 While further research is needed in this area, Tai Chi is gentle and safe for most patients.38,39 A TCM PRACTITIONER’S PERSPECTIVE The first author (MS) is a TCM practitioner in an integrative medicine clinic associated with an academic medical center. A typical treatment plan for symptomatic cancer patients involves weekly acupuncture treatment (which may include auricular, full body, and/or electro-acupuncture), nutritional advice, sleep schedule, and favorite activity or exercise program. There is direct communication with the oncology team via a computerized charting system regarding the treatment plan, changes in patient condition, laboratory and imaging study findings, changes in medications and herbs/supplements. Many patients find this integrative, approach satisfying and empowering during and after cancer care. An example of a recent case involves a 74-yearold married man presenting with a diagnosis of stage 4 metastatic prostate cancer. He was a researcher and exposed to long-term high levels of radiation in his field of work. He is religious and spiritual in his belief system. His chief complaint was upper back pain, 8/10 on VAS, for 3 months. Location of pain was the left paraspinous region on the urinary bladder channel/meridian. He was alternating extra strength acetaminophen and ibuprofen for 3 months without relief. Rest improved his pain and activity aggravated it. Heat applied to the local area improved his pain and cold worsened it. Because of his pain, he was unable to participate in his favorite activity, which is to sit and play cards with his friends in the evenings. Other complaints included insomnia, anxiety, hot flashes and night sweats, irritable bowel, and loss of sexual function. He presented with a list of supplements that he had selfprescribed. The patient was placed on Lupron Depot IM monthly (hence his hot flashes and night sweats as a side effect) by his oncologist, but no other drugs nor chemotherapy agents were prescribed. A oncology clinic note included a detailed history with recent labs and imaging studies. 72 M.E. SMITH AND S. BAUER-WU The TCM assessment revealed a purple tongue and excess pulse, suggesting a TCM diagnosis of Qi and blood stagnation of the urinary channel resulting in blood stasis at stage 3. The patient was interested in adding any appropriate supplements to his list and inquired about dietary advice. Recommendations were as follows: gluten-free diet (because past history revealed he had gluten sensitivity with irritable bowel symptoms), at least 4 daily servings of steamed organic yellow/green and organic cruciferous vegetables (for beneficial antioxidants and flavonoids), vegetable or fruit smoothies, fishes high in Omega 3 such as salmon two to three times weekly, and daily green tea. Daily shitake and reishi mushroom extract for immune system enhancement were also suggested. He was instructed on correct sleeping position and posture to reduce pain and promote comfort. The patient received 30 minutes of electro-acupuncture to the upper back and spine in combination with auricular acupuncture to assist in resolving blood stasis. Upon return for a follow-up visit 6 days later, the patient reported significant relief in his upper back pain from the acupuncture treatment with a pain scale being 3/10 on VAS. He received weekly treatment sessions for 1 month, followed with bi-weekly sessions. All supplement/dietary recommendations and procedures were dictated in the patient’s medical chart for all providers over the patient’s care to review. Within 3 weeks the patient was able to play cards with his friends because of a reduction in pain and from appropriate sleep and rest. He also had a reduction in frequency and intensity of hot flashes with night sweats by approximately 50%, improving his insomnia. The patient continues with bi-weekly TCM sessions with a pain score of 2 on a 10-point VAS. Because the patient did not initially receive relief from the pain medications, he elected to discontinue them. A large portion of each treatment session included allowing him to express his feelings and concerns and providing a safe environment for him to cry. Listening, consoling, and providing support have been beneficial in allowing him to grieve his own illness. He was encouraged to attend support groups in the community and was referred to a counselor and an Integrative Medicine doctor for coordination of integrative care early in the course of his treatment. As a TCM practitioner, the interpersonal approach to patient care includes the following: 1. Being non judgmental, which includes understanding the healing process is not always physical nor attached to a particular outcome. 2. Being focused in the moment with the patient and accepting the patient where they are in all aspects of their life, which assists in developing a trusting relationship for healing. 3. Seeing the patient as a person with feelings, which assists the TCM practitioner in treating the person, not their disease or condition. 4. Empowering the patient to assist in emotional, physical, and spiritual healing. 5. Listening and acting on the patient’s personal goals (without personal bias) and providing information in a timely manner without overwhelming the patient. 6. Allowing patients to grow in their own experience of health and healing while promoting a connection to their own personal spiritual source. FINDING A QUALIFIED TCM PRACTITIONER Now that acupuncture and TCM are rapidly entering the mainstream of medicine in North America, an increasing number of nurses, physicians, and lay people are interested in finding a qualified practitioner to refer their patients. The laws are different in every state, and some states, like New Mexico and California, have very stringent licensing standards for practice. Fortunately, there are certifying agencies that establish standards that a practitioner must meet to be qualified. The most established is the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM) in Washington, DC. The NCCAOM website (www.nccaom.org) lists practitioners who are qualified to practice throughout the country.8 After the completion of 3 to 4 years of study in an accredited school of Oriental Medicine, a student can sit for the licensing boards. Certification is used as the basis for licensure in 90% of the states that have set standards for practicing acupuncture. INSURANCE COVERAGE AND COST Medicare and Medicaid do not cover acupuncture and other Chinese medicine treatments; however, these treatments are covered under many supplemental health plans and employee TRADITIONAL CHINESE MEDICINE FOR CANCER-RELATED SYMPTOMS medical benefit plans. The patient is responsible for contacting the health insurance provider to find out if the practitioner and treatments are covered. The patient can also check with their employer, if receiving health benefits at work, to see if TCM treatments are covered through their health plan. If insurance does not cover a Chinese medicine office visit, the out-of-pocket cost in most parts of the country ranges from $100 to $150 for the initial session and $65 to $85 for basic follow-up acupuncture treatment. RECOMMENDATIONS FOR ONCOLOGY NURSES The most common risk associated with TCM is related directly to herb-drug interactions. Cancer patients often take a number of different medications, antineoplastics, and other drugs to manage symptoms, and typical Chinese herbal medicine regimens often use a number of combined herbs. Potential negative herb-drug interactions include increased toxicity or diminished treatment effects.32 Caution must be taken 73 to minimize these risks through thorough assessment and ongoing communication between the oncology and TCM teams. While acupuncture is considered to be quite safe, it is not without risks.6,7 The risk of significant adverse events with acupuncture is very low, less than 0.55 per 10,000 individuals.6-8 Mild side effects, like needle sensation and bruising at the needle site, can occur during acupuncture treatment and is common even with the most experienced and qualified practitioner. Of note, acupuncture within the radiation field should be avoided.6 Oncology nurses can guide cancer patients to increase their physical activity through Tai Chi by pursuing a community Tai Chi class or watching videotapes, if homebound. Oncology nurses need to stay informed of the growing body of evidence on TCM for cancer patients and be aware of resources and qualified TCM practitioners in their community. TCM offers opportunities to help to alleviate unpleasant symptoms associated with cancer and untoward effects of conventional cancer treatment. REFERENCES 1. Williams T.
