Acupuncture for Chemotherapy-Induced Peripheral Neuropathy in Breast Cancer Survivors: A Randomized Controlled Pilot Trial.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most debilitating long-term side effects in breast cancer survivors. We conducted a randomized controlled pilot trial to assess the feasibility, safety, and effects of an acupuncture intervention on CIPN in this population. PATIENTS AND METHODS: Women with stage I-III breast cancer with grade 1 or higher CIPN after taxane-containing adjuvant chemotherapy were randomized 1:1 to an immediate acupuncture (IA) arm or to a waitlist control group (CG). Participants in the IA arm received 18 sessions of acupuncture over 8 weeks, then received no additional acupuncture. Patients in the CG arm received usual care over 8 weeks, followed by nine sessions of acupuncture over 8 weeks. Measures including Patient Neurotoxicity Questionnaire (PNQ), Functional Assessment of Cancer Therapy-Neurotoxicity subscale (FACT-NTX), and Brief Pain Inventory-short form (BPI-SF) were collected at baseline and at 4, 8, and 16 weeks after enrollment. RESULTS: Forty women (median age, 54) were enrolled (20 to IA and 20 to CG), with median time between completion of chemotherapy and enrollment of 14 months (range 1-92). At 8 weeks, participants in the IA arm experienced significant improvements in PNQ sensory score (-1.0 ± 0.9 vs. -0.3 ± 0.6; p = .01), FACT-NTX summary score (8.7 ± 8.9 vs. 1.2 ± 5.4; p = .002), and BPI-SF pain severity score (-1.1 ± 1.7 vs. 0.3 ± 1.5; p = .03), compared with those in the CG arm. No serious side effects were observed. CONCLUSION: Women with CIPN after adjuvant taxane therapy for breast cancer experienced significant improvements in neuropathic symptoms from an 8-week acupuncture treatment regimen. Additional larger studies are needed to confirm these findings. IMPLICATIONS FOR PRACTICE: Chemotherapy-induced peripheral neuropathy (CIPN) is a toxicity that often persists for months to years after the completion of adjuvant chemotherapy for early breast cancer. In a randomized pilot trial of 40 breast cancer survivors with CIPN, an 8-week acupuncture intervention (vs. usual care) led to a statistically and clinically significant improvement in subjective sensory symptoms including neuropathic pain and paresthesia. Given the lack of effective therapies and established safety profile of acupuncture, clinicians may consider acupuncture as a treatment option for mild to moderate CIPN in practice.

Botanical Formula LCS101: A Multi-Targeted Approach to Cancer Care.

BACKGROUND AND PURPOSE: LCS101 is a botanical formula extracted from 14 botanical components. While conventional oncology focuses on targeted medicine, research on LCS101 adopts a multi-targeted approach, examining its preclinical (in vitro, in vivo, and ex vivo) and clinical (randomized controlled trial, pragmatic) effects. This includes examining the formula's impact on the immune system, selective anticancer effects, and improved chemotherapy-related symptoms and quality of life. Effects on the Immune System: In murine splenic cell cultures, LCS101 significantly increased T-cell proliferation and macrophage tumor necrosis factor-α production. Blood samples from healthy volunteers exposed to LCS101 showed a dose-dependent increase in natural killer cell activity; and a randomized controlled trial showed significantly lower rates of leucopenia/neutropenia and anemia in patients with breast cancer undergoing chemotherapy. Selective Anticancer Effects: In vitro LCS101 demonstrated selective growth inhibition (on XTT viability assay) in human breast and prostate cancer cell lines, without any harmful effects on normal human epithelial cells. The anticancer effects were attributed to reactive oxygen species activity. Cytotoxic effects of doxorubicin and 5-fluorouracil on breast cancer cell lines were significantly increased following exposure to LCS101, with a protective effect in normal cells. Symptom Relief and Quality of Life: Clinical research shows that patients taking LCS101 during chemotherapy are less likely to report symptoms such as fatigue, pain, nausea and vomiting. CONCLUSION: LCS101 exhibits multi-targeted effects, with significant implications for cancer care. Further research is needed to better understand the impact of these findings.

Oncology Acupuncture for Chronic Pain in Cancer Survivors: A Reflection on the American Society of Clinical Oncology Chronic Pain Guideline.

Chronic pain syndromes associated with cancer treatment are common but difficult to manage. The American Society of Clinical Oncology recently published a practice guideline to address the unmet needs of cancer survivors, Management of Chronic Pain in Survivors of Adult Cancers, which stresses the importance of implementing integrative therapies including acupuncture. This review focuses on randomized clinical trials of acupuncture for chronic pain in cancer survivors, including its use in chemotherapy-induced peripheral neuropathy, aromatase inhibitor-associated arthralgia, and post neck dissection pain, and provides future directions of oncology acupuncture research in cancer survivorship. The features of oncology acupuncture are also discussed.

Acupuncture for Chemoradiation Therapy-Related Dysphagia in Head and Neck Cancer: A Pilot Randomized Sham-Controlled Trial.

INTRODUCTION: Dysphagia is common in head and neck cancer patients after concurrent chemoradiation therapy (CRT). This study evaluated the feasibility of conducting a randomized sham-controlled trial and collected preliminary data on safety and efficacy of acupuncture. PATIENTS AND METHODS: Head and neck cancer (HNC) patients with stage III-IV squamous cell carcinoma were randomized to 12 sessions of either active acupuncture (AA) or sham acupuncture (SA) during and following CRT. Patients were blinded to treatment assignment. Swallowing-related quality of life (QOL) was assessed using the MD Anderson Dysphagia Inventory (MDADI) total and subscale scores. RESULTS: Multiple aspects of trial feasibility were confirmed. Forty-two of 196 patients screened (21%) were enrolled and randomized to receive AA (n = 21) or SA (n = 21); 79% completed at least 10 of 12 planned acupuncture sessions; 81% completed the study follow-ups. The majority of patients reported uncertainty regarding their treatment assignment, with no difference between the AA and SA groups. Audits confirmed both AA and SA treatments were delivered with high fidelity. No serious acupuncture-related side effects were observed. MDADI total scores significantly improved from baseline to 12 months post-CRT in both groups (AA: +7.9; SA +13.9; p = .044, p < .001). Similar patterns were observed for the MDADI global subscale (AA: +25.0; SA +22.7; p = .001, p = .002). Intent-to-treat analyses suggested no difference between the treatment groups (p = .17, p = .76 for MDADI total and global scores, respectively). CONCLUSION: A sham-controlled randomized trial evaluating acupuncture in dysphagia-related QOL in HNC found the procedure to be feasible and safe. Further investigation is required to evaluate efficacy. IMPLICATIONS FOR PRACTICE: Dysphagia or swallowing difficulty is an important and common condition after concurrent chemoradiation therapy in head and neck cancer patients. In addition to current available supportive care, acupuncture may offer potential for treating dysphagia. This study demonstrated that both active acupuncture and sham acupuncture are safe and were associated with improved dysphagia-related quality of life from baseline to 12 months after concurrent chemoradiation therapy. This study was not designed to inform underlying specific versus nonspecific effects. Future larger-scale pragmatic clinical trials evaluating the effectiveness of acupuncture versus standard of care are warranted, and further mechanistic research is needed to understand how active versus purportedly sham acupuncture procedures affect dysphagia-related symptoms.

Acupuncture for Aromatase Inhibitor-Induced Arthralgia: A Systematic Review.

BACKGROUND: Aromatase inhibitors (AIs) are commonly used as adjunctive hormone treatment for early breast cancer patients. The major side effect of AIs is arthralgia, which affects adherence. Previous reviews suggested that acupuncture is effective in the management of cancer-related pain. The aim of this review is to evaluate the effects of acupuncture on arthralgia caused by AIs. METHODS: This article examined randomized controlled trials (RCTs) measuring the effects of acupuncture on joint symptoms caused by AIs within 8 medical databases till May 2014. The quality of the articles was evaluated according to the Cochrane risk of bias (ROB) tool. RESULTS: Four RCTs were identified in medical journals. Two studies were conducted with manual acupuncture and 2 studies were electroacupuncture. The range of sample size was between 32 and 67. One RCT showed significant improvement in the acupuncture group compared with the sham control group and another RCT showed a statistical difference between the electroacupuncture and waitlist group. The other 2 studies showed no statistical differences between control and acupuncture groups. Two studies conducted blood analysis to elucidate the mechanism of efficacy of acupuncture for arthralgia. The 2 positive studies had a lower ROB and 2 studies had a high ROB. CONCLUSIONS: The systematic review suggests that acupuncture has potential benefits to improve arthralgia caused by AIs. However, further trials of adequate sample size, appropriate control group, and longer follow-up are necessary to investigate the efficacy of acupuncture in AI-induced arthralgia.

Acupuncture for cancer pain and related symptoms.

Cancer pain is one of most prevalent symptoms in patients with cancer. Acupuncture and related techniques have been suggested for the management of cancer pain. The National Comprehensive Cancer Network guidelines for adult cancer pain recommends acupuncture, as one of several integrative interventions, in conjunction with pharmacologic intervention as needed. This review presents the latest available evidence regarding the use of acupuncture for cancer pain. It also provides "actionable" acupuncture protocols for specific cancer pain conditions and related symptoms in order to provide more clinically relevant solutions for clinicians and cancer patients with pain. These conditions include postoperative cancer pain, postoperative nausea and vomiting, postsurgical gastroparesis syndrome, opioid-induced constipation, opioid-induced pruritus, chemotherapy-induced neuropathy, aromatase inhibitor-associated joint pain, and neck dissection-related pain and dysfunction.

Acupuncture for dysphagia after chemoradiation in head and neck cancer: rationale and design of a randomized, sham-controlled trial.

INTRODUCTION: Dysphagia is a common side effect following chemoradiation therapy (CRT) in head and neck cancer (HNC) patients. Current dysphagia management includes swallowing therapy and dilation procedures, but these treatments have limitations. While acupuncture has been reported to positively impact swallowing function and quality of life (QOL) in patients with dysphagia, current evidence is inconclusive. MATERIAL AND METHODS: In an ongoing trial, 42 squamous cell carcinoma HNC patients, who are receiving platinum-based CRT with curative intent, are being recruited from a comprehensive cancer center. They are randomized to 12 sessions of either active acupuncture or to sham acupuncture during and following CRT over a 24-week period. Blinded research staff assesses outcomes at baseline, 20 weeks post-CRT (end of acupuncture), and 12 months after baseline (6-month follow-up). The primary outcome is change in M.D. Anderson Dysphagia Inventory score from baseline to 12 months. Secondary outcomes include QOL measures pertaining to HNC patients. In addition, a subset of study patients are tested for salivary flow rates and cytokines, including plasma transforming growth factor-ß1 and interleukin 6 (n=10 per arm), to preliminarily explore the biological mechanisms of acupuncture for dysphagia. DISCUSSION: This paper addresses unique challenges related to study design in nonpharmacological, sham-controlled acupuncture trials including development of evidence-based credible verum and sham treatment protocols, blinding, and assuring fidelity of treatment. Results of this study will inform the feasibility of conducting a large scale trial and will provide preliminary evidence regarding the value of acupuncture for dysphagia in HNC patients.

The Feasibility and Effects of Acupuncture on Quality of Life Scores During Chemotherapy in Ovarian Cancer: Results from a Pilot, Randomized Sham-Controlled Trial.

BACKGROUND: Within a pilot trial regarding chemotherapy-induced neutropenia, the secondary aim of the main study was explored. This involved measuring the effects-as shown on two key measurement scales reflecting quality of life (QoL)-of verum versus sham acupuncture on patients with ovarian cancer during chemotherapy. OBJECTIVE: The aim of this substudy was to determine the feasibility of determining the effects of verum acupuncture versus sham acupuncture on QoL in patients with ovarian cancer during chemotherapy. DESIGN: This was a randomized, sham-controlled trial. SETTING: The trial was conducted at two cancer centers. PATIENTS: Patients with ovarian cancer (N=21) who were receiving chemotherapy-primarily intravenous carboplatin and paclitaxel-participated in this substudy. INTERVENTION: The participants were given either active or sham acupuncture 1 week prior to cycle 2 of chemotherapy. There were ten sessions of acupuncture, with manual and electro-stimulation over a 4-week period. MAIN OUTCOME MEASURES: The European Organization for Research and Treatment of Cancer-Quality-of-Life Questionnaire-Core 30 Item (EORTC-QLQ-C30) and the Quality of Life Questionnaire-Ovarian Cancer Module-28 Item (QLQ-OV28) were administered to the patients at baseline and at the end of their acupuncture sessions. RESULTS: Of the original 21, 15 patients (71%) completed the study, and 93% of them completed the questionnaires. The EORTC-QLQ-C30 subscores were improved in the acupuncture arm, including the mean scores of social function (SF), pain, and insomnia (p=0.05). However, after adjusting for baseline differences, only the SF score was significantly higher in the active acupuncture arm, compared with the sham acupuncture arm (p=0.03). CONCLUSIONS: It appears feasible to conduct a randomized sham-controlled acupuncture trial measuring QoL for patients with ovarian cancer who are undergoing chemotherapy. Acupuncture may have a role in improving QoL during chemotherapy.

Effect of medical Qigong on cognitive function, quality of life, and a biomarker of inflammation in cancer patients: a randomized controlled trial.

PURPOSE: Cancer patients often experience diminished cognitive function (CF) and quality of life (QOL) due to the side effects of treatment and the disease symptoms. This study evaluates the effects of medical Qigong (MQ; combination of gentle exercise and meditation) on CF, QOL, and inflammation in cancer patients. METHODS: Eighty-one cancer patients recruited between October 2007 and May 2008 were randomly assigned to two groups: a control group (n = 44) who received the usual health care and an intervention group (n = 37) who participated in a 10-week MQ program. Self-reported CF was measured by the European Organization for Research and Treatment of Cancer (EORTC-CF) and the Functional Assessment of Cancer Therapy-Cognitive (FACT-Cog). The Functional Assessment of Cancer Therapy-General (FACT-G) was used to measure QOL. C-reactive protein (CRP) was assessed as a biomarker of inflammation. RESULTS: The MQ group self-reported significantly improved CF (mean difference (MD) = 7.78, t (51) = -2.532, p = 0.014) in the EORTC-CF and all the FACT-Cog subscales [perceived cognitive impairment (MD = 4.70, t (43) = -2.254, p = 0.029), impact of perceived cognitive impairment on QOL (MD = 1.64, t (45) = -2.377, p = 0.024), and perceived cognitive abilities (MD = 3.61, t (45) = -2.229, p = 0.031)] compared to controls. The MQ group also reported significantly improved QOL (MD = 12.66, t (45) = -5.715, p < 0.001) and had reduced CRP levels (MD = -0.72, t (45) = 2.092, p = 0.042) compared to controls. CONCLUSIONS: Results suggest that MQ benefits cancer patients' self-reported CF, QOL, and inflammation. A larger randomized controlled trial including an objective assessment of CF is planned.

Effects of complementary therapies on clinical outcomes in patients being treated with radiation therapy for prostate cancer.

BACKGROUND: This pilot randomized controlled trial (RCT) examined the clinical effects of 2 complementary (CAM) therapies, relaxation response therapy (RRT) and Reiki therapy, in men being treated with external beam radiotherapy (EBRx) for prostate cancer. METHODS: Study participants were randomly assigned to weekly RRT, Reiki therapy twice weekly, or wait-list control. Well-validated instruments measured anxiety (STAI), depression (CES-D), and quality of life in cancer patients (FACT-G) at randomization and 3 subsequent time points. RESULTS: Fifty-four men were randomized, and 16 of 18 (89%) of RRT and 15 of 18 (83%) of Reiki patients completed the intervention protocol. No statistically significant difference was found between the RRT, Reiki, and control groups on total scores for the STAI, CES-D, or FACT-G instruments at any time point. However, at the end of the intervention, significant improvement was found on the emotional well-being subscale of the FACT-G quality of life scale in the RRT group compared with the Reiki and control groups (P = .01). In participants who were classified as "anxious" at baseline, statistically significant improvement occurred in the RRT group (P = .02), and a positive trend was found in the Reiki group (P = .10). CONCLUSIONS: This pilot study documented the feasibility of conducting a RCT of CAM therapies in men undergoing EBRx for prostate cancer. Relaxation response therapy improved emotional well being and eased anxiety in participants. Reiki therapy also had a positive effect in anxious patients. A larger study to verify and better define the benefits of these therapies in men with prostate cancer is warranted.

Recent advances in oncology acupuncture and safety considerations in practice.

Oncology acupuncture is a new and emerging field of research. Recent advances from published clinical trials have added evidence to support the use of acupuncture for symptom management in cancer patients. Recent new developments include (1) pain and dysfunction after neck dissection; (2) radiation-induced xerostomia in head and neck cancer; (3) aromatase inhibitor-associated arthralgia in breast cancer; (4) hot flashes in breast cancer and prostate cancer; and (5) chemotherapy-induced neutropenia in ovarian cancer. Some interventions are becoming a non-pharmaceutical option for cancer patients, while others still require further validation and confirmation. Meanwhile, owing to the rapid development of the field and increased demands from cancer patients, safety issues concerning oncology acupuncture practice have become imperative. Patients with cancer may be at higher risk developing adverse reactions from acupuncture. Practical strategies for enhancing safety measures are discussed and recommended.

Acupuncture for dysphagia after chemoradiation therapy in head and neck cancer: a case series report.

BACKGROUND: Dysphagia is a common side effect following chemoradiation therapy (CRT) in patients with head and neck cancer (HNC). METHODS: In this retrospective case series, 10 patients with HNC were treated with acupuncture for radiation-induced dysphagia and xerostomia. All patients were diagnosed with stage III/IV squamous cell carcinoma. In all, 7 of 10 patients were percutaneous endoscopic gastrostomy (PEG) tube dependent when they began acupuncture. Manual acupuncture and electroacupuncture were used once a week. RESULTS: A total of 9 of 10 patients reported various degrees of subjective improvement in swallowing functions, xerostomia, pain, and fatigue levels. Overall, 6 (86%) of 7 PEG tube-dependent patients had their feeding tubes removed after acupuncture, with a median duration of 114 days (range 49 to 368 days) post CRT. One typical case is described in detail. CONCLUSIONS: A relatively short PEG tube duration and reduced symptom severity following CRT were observed in these patients. Formal clinical trials are required to determine the causality of the observations.

Acupuncture as palliative therapy for physical symptoms and quality of life for advanced cancer patients.

BACKGROUND: Acupuncture is underutilized as an adjunct cancer therapy. The main study objectives were to determine the feasibility of administering acupuncture as palliative therapy to patients with advanced ovarian or breast cancer and to assess the effect on symptoms and quality of life (QOL). METHODS: This study was a pilot, single-armed prospective clinical trial for patients with advanced cancer to receive 12 acupuncture sessions over 8 weeks with follow-up at weeks 9 and 12. Ambulatory patients with advanced ovarian or breast cancer were enrolled to receive treatments at an outpatient academic oncology center. Symptom severity was measured before and after each acupuncture session.A composite QOL assessment tool, consisting of validated instruments, was completed at 5 time points. RESULTS: Forty patients enrolled in the study. Twenty-eight patients (70%; 95% confidence interval [CI] = 53%-83%) completed 4 weeks of treatment, and 26 patients (65%; 95% CI = 48%-79%) completed 8 weeks. Eight patients (20%) withdrew before receiving acupuncture, and 6 patients (15%) discontinued treatment early because of disease progression or scheduling demands. Among all 32 assessed patients, there was self-reported improvement immediately post-treatment in anxiety,fatigue, pain, and depression and significant improvement over time for patients with anxiety (P = .001) and depression(P = .02). Among patients experiencing baseline symptoms, there was improvement in anxiety (P = .001), fatigue (P = .0002),pain (P = .0002), and depression (P = .003). QOL measures of pain severity and interference, physical and psychological distress, life satisfaction, and mood states showed improved scores during treatment, with sustained benefit at 12 weeks. CONCLUSIONS: This pilot study demonstrates that an 8-week outpatient acupuncture course is feasible for advanced cancer patients and produces a measurable benefit that should be evaluated in controlled trials.

Integrative Tumor Board: a case report and discussion from Dana-Farber Cancer Institute.

A 34-year-old woman carrying a BRCA1 gene and a significant family history was diagnosed with T1c, N1 breast cancer. The tumor was estrogen receptor, progesterone receptor, and HER-2/Neu negative. The patient received dose-dense chemotherapy with Adriamycin and Cytoxan followed by Taxol, and left breast irradiation. Later, a bilateral S-GAP flap reconstruction with right prophylactic mastectomy and left mastectomy were performed. During her treatment, the patient had an integrative medicine consultation and was seen by a team of health care providers specializing in integrative therapies, including integrative nutrition, therapeutic massage, acupuncture, and yoga. Each modality contributed unique benefit in her care that led to a satisfactory outcome for the patient. A detailed discussion regarding her care from each modality is presented. The case elucidates the need for integrative approaches for cancer patients in a conventional medical setting.

Acupuncture for chemotherapy-induced neutropenia in patients with gynecologic malignancies: a pilot randomized, sham-controlled clinical trial.

OBJECTIVES: The objective of this study was to investigate the effect of acupuncture administered during myelosuppressive chemotherapy on white blood cell (WBC) count and absolute neutrophil count (ANC) in patients with ovarian cancer. DESIGN: This study is a pilot, randomized, sham-controlled clinical trial. Patients received active acupuncture versus sham acupuncture while undergoing chemotherapy. A standardized acupuncture protocol was employed with manual and electrostimulation. The frequency of treatment was 2-3 times per week for a total of 10 sessions, starting 1 week before the second cycle of chemotherapy. SETTING: The setting was two outpatient academic centers for patients with cancer. SUBJECTS: Twenty-one (21) newly diagnosed and recurrent ovarian cancer patients were the subjects. OUTCOME MEASURES: WBC count, ANC, and plasma granulocyte colony-stimulating factor (G-CSF ) were assessed weekly. RESULTS: The median leukocyte value in the acupuncture arm at the first day of the third cycle of chemotherapy was significantly higher than in the control arm after adjusting for baseline value (8600 cells/microL, range: 4800-12,000 versus 4400 cell/microL, range: 2300-10,000) (p = 0.046). The incidence of grade 2-4 leukopenia was less in the acupuncture arm than in the sham arm (30% versus 90%; p = 0.02). However, the median leukocyte nadir, neutrophil nadir, and recovering ANC were all higher but not statistically significantly different (p = 0.116-0.16), after adjusting for baseline differences. There were no statistically significant differences in plasma G-CSF between the two groups. CONCLUSIONS: We observed clinically relevant trends of higher WBC values during one cycle of chemotherapy in patients with ovarian cancer, which suggests a potential myeloprotective effect of acupuncture. A larger trial is warranted to more definitively determine the efficacy of acupuncture on clinically important outcomes of chemotherapy-induced neutropenia.

The value of acupuncture in cancer care.

Clinical research on acupuncture in cancer care is a new and challenging field in oncology. The results of clinical research will continue to provide clinically relevant answers for patients and oncologists. The evidence currently available has suggested that acupuncture is a safe and effective therapy to manage cancer and treatment related symptoms, while giving patients the ability to actively participate in their own care plan. The article explains the potential benefits of acupuncture and describes the difficulties in studying its effectiveness.

Acupuncture for chemotherapy-induced leukopenia: exploratory meta-analysis of randomized controlled trials.

Chemotherapy-induced leukopenia and neutropenia are common side effects during cancer treatment. Acupuncture has been reported as an adjunct therapy for this complication. The current study reviewed published randomized controlled trials of acupuncture's effect and explored the acupuncture parameters used in these trials. We searched biomedical databases in English and Chinese from 1979 to 2004. The study populations were cancer patients who were undergoing or had just completed chemotherapy or chemoradiotherapy, randomized to either acupuncture therapy or usual care. The methodologic quality of trials was assessed. From 33 reviewed articles, 682 patients from 11 eligible trials were included in analyses. All trials were published in non-PubMed journals from China. The methodologic quality of these trials was considerably poor. The median sample size of each comparison group was 45, and the median trial duration was 21 days. The frequency of acupuncture treatment was once a day, with a median of 16 sessions in each trial. In the seven trials in which white blood cell (WBC) counts were available, acupuncture use was associated with an increase in leukocytes in patients during chemotherapy or chemoradiotherapy, with a weighted mean difference of 1,221 WBC/muL on average (95% confidence interval 636-1,807; p < .0001). Acupuncture for chemotherapy-induced leukopenia is an intriguing clinical question. However, the inferior quality and publication bias present in these studies may lead to a false-positive estimation. Meta-analysis based on these published trials should be treated in an exploratory nature only.

Integrative medicine in hematology/oncology: benefits, ethical considerations, and controversies.

Integrative Medicine (IM), a newly emerging field, has evolved from Complementary and Alternative Medicine (CAM). CAM refers to diverse medical and health care systems, practices, and products that are not presently considered part of conventional medicine and generally have limited scientific evidence. In the US, CAM is a multi-billion dollar, unregulated industry with potential benefits and risks to consumers, including cancer patients, who are high utilizers of complementary therapies. Patients' CAM use often is unsupervised by physicians, yet patients need the advice and guidance of their hematologists/oncologists as part of total cancer care. Ethical and legal issues physicians need to address include inquiring about and educating patients regarding potential interactions (e.g., drug-herb, radiation-antioxidant) or product contaminants, while discussing other therapies that may alleviate symptoms and/or improve quality of life. Administratively, CAM offerings in medical settings require relevant policies and procedures, such as properly credentialing practitioners and providing financial assistance counseling for those who cannot afford fee-for-service. Unlike "Alternative Medicine," the goal of IM is to combine mainstream medical therapies and CAM therapies (e.g., acupuncture, meditation, music therapy) that have some high-quality scientific evidence of safety and effectiveness. The Society for Integrative Oncology (SIO), a new international organization of oncology professionals studying and integrating effective complementary therapies in cancer care, serves as a forum for presenting scientific data on these therapies while emphasizing the importance of developing infrastructure that promotes IM principles and practices. The ultimate goal is to develop multidisciplinary expertise and therapeutic synergy between conventional and complementary therapies.
