Purpose: Many cancer centers offer acupuncture services. To date, a comprehensive systematic review of acupuncture in cancer care has not been conducted. The purpose of this review was to evaluate the efficacy of acupuncture for symptom management in patients with cancer. Methods: Medline, Embase, CINAHL, Cochrane (all databases), Scopus, and PubMed were searched from inception through December 2011 for prospective randomized clinical trials (RCT) evaluating acupuncture for symptom management in cancer care. Only studies involving needle insertion into acupuncture points were included. No language limitations were applied. Studies were assessed for risk of bias (ROB) according to Cochrane criteria. Outcomes by symptom were designated as positive, negative, or unclear. Results: A total of 2,151 publications were screened. Of those, 41 RCTs involving eight symptoms (pain, nausea, hot flashes, fatigue, radiation-induced xerostomia, prolonged postoperative ileus, anxiety/mood disorders, and sleep disturbance) met all inclusion criteria. One positive trial of acupuncture for chemotherapy-induced nausea and vomiting had low ROB. Of the remaining studies, eight had unclear ROB (four positive, three negative, and one with unclear outcomes). Thirty-three studies had high ROB (19 positive, 11 negative, and three with both positive and negative outcomes depending on the symptom). Conclusion: Acupuncture is an appropriate adjunctive treatment for chemotherapy-induced nausea/vomiting, but additional studies are needed. For other symptoms, efficacy remains undetermined owing to high ROB among studies. Future research should focus on standardizing comparison groups and treatment methods, be at least single-blinded, assess biologic mechanisms, have adequate statistical power, and involve multiple acupuncturists.

BACKGROUND: Huachansu, a Chinese medicine that comes from dried toad venom from the skin glands of Bufo gargarizans or B. melanostictus, has been used in the treatment of various cancers in China. The authors conducted a pilot study, using a phase 1 trial design, of huachansu in patients with advanced cancer.METHODS: Huachansu was administered intravenously for 14 days followed by 7 days off (1 cycle). Without significant adverse events or progressive disease, treatment continued beyond 2 cycles. The dose of huachansu was escalated as follows with 3 patients per cohort: 10 (level 1), 20 (level 2), 40 (level 3), 60 (level 4), and 90 (level 5) mL/m2.RESULTS: Fifteen patients (hepatocellular cancer, n = 11; nonsmall cell lung cancer, n = 2; pancreatic cancer, n = 2) were enrolled in the trial, and no dose‐limiting toxicities (DLTs) were found. Eleven patients had no drug‐related toxicity greater than grade 1. Six (40%) had stable disease (median duration, 6.0 months; range, 3.5‐11.1 months). One of these patients (with hepatocellular cancer) had 20% regression (duration, 11 months) (dose level 1). Quality of life improved for patients with stable disease. Plasma bufalin concentration reached maximal levels at the end of the 2‐hour infusion and was proportional to the amount of drug being administered (0.81‐3.38 ng/mL).CONCLUSIONS: No DLT was observed with the use of huachansu at doses up to 8× higher than typically used in China. Six patients had prolonged stable disease or minor tumor shrinkage. Cancer 2009. © 2009 American Cancer Society.

Purpose: Previous research incorporating yoga (YG) into radiotherapy (XRT) for women with breast cancer finds improved quality of life (QOL). However, shortcomings in this research limit the findings. Patients and Methods: Patients with stages 0 to III breast cancer were recruited before starting XRT and were randomly assigned to YG (n = 53) or stretching (ST; n = 56) three times a week for 6 weeks during XRT or waitlist (WL; n = 54) control. Self-report measures of QOL (Medical Outcomes Study 36-item short-form survey; primary outcomes), fatigue, depression, and sleep quality, and five saliva samples per day for 3 consecutive days were collected at baseline, end of treatment, and 1, 3, and 6 months later. Results: The YG group had significantly greater increases in physical component scale scores compared with the WL group at 1 and 3 months after XRT (P = .01 and P = .01). At 1, 3, and 6 months, the YG group had greater increases in physical functioning compared with both ST and WL groups (P < .05), with ST and WL differences at only 3 months (P < .02). The group differences were similar for general health reports. By the end of XRT, the YG and ST groups also had a reduction in fatigue (P < .05). There were no group differences for mental health and sleep quality. Cortisol slope was steepest for the YG group compared with the ST and WL groups at the end (P = .023 and P = .008) and 1 month after XRT (P = .05 and P = .04). Conclusion: YG improved QOL and physiological changes associated with XRT beyond the benefits of simple ST exercises, and these benefits appear to have long-term durability.

BACKGROUND: Radiotherapy may lead to side effects that undermine patients' quality of life (QOL). Although mind‐body practices like qigong appear to improve QOL in cancer survivors, little is known about their benefits for patients who are receiving radiotherapy. Thus, in the current randomized controlled trial, the authors examined the efficacy of a qigong intervention on QOL in women with breast cancer during and after treatment.METHODS: Ninety‐six women with breast cancer were recruited from a cancer center in Shanghai, China, and were randomized to a qigong group (N = 49) or a waitlist control group (N = 47). Women in the qigong group attended 5 weekly classes over 5 or 6 weeks of radiotherapy. QOL outcomes (ie, depressive symptoms, fatigue, sleep disturbance, and overall QOL) and cortisol slopes were assessed at baseline, during treatment, at the end of treatment, 1 month later, and 3 months later.RESULTS: The mean age of the women was 46 years (range, 25‐64 years). Seven percent of women had stage 0 disease, 25% had stage I disease, 40% had stage II disease, and 28% had stage III disease. Fifty‐four percent of women underwent mastectomy. Multilevel analyses revealed that women in the qigong group reported less depressive symptoms over time than women in the control group (P = .05). Women who had elevated depressive symptoms at the start of radiotherapy reported less fatigue (P < .01) and better overall QOL (P < .05) in the qigong group compared with the control group, and these findings were clinically significant. No significant differences were observed for sleep disturbance or cortisol slopes.CONCLUSIONS: The current results indicated that qigong may have therapeutic effects in the management of QOL among women who are receiving radiotherapy for breast cancer. Benefits were particularly evident for patients who had preintervention elevated levels of depressive symptoms. Cancer 2013. © 2013 American Cancer Society.
