Efficacy of Complementary and Alternative Medicine Therapies in Relieving Cancer Pain: A Systematic Review

PURPOSE Despite widespread popular use of complementary and alternative medicine (CAM) therapies, a rigorous evidence base about their efficacy for cancer-related pain is lacking. This is a systematic review of randomized controlled trials (RCTs) evaluating CAM therapies for cancer-related pain. METHODS RCTs using CAM interventions for cancer-related pain were abstracted using Medline, EMBASE, CINAHL, AMED, and Cochrane database. RESULTS Eighteen trials were identified (eight poor, three intermediate, and seven high quality based on Jadad score), with a total of 1,499 patients. Median sample size was 53 patients, and median intervention duration was 45 days. All studies were from single institutions, four had sample size justification, and none reported any adverse effects. Seven trials reported significant benefit for the following CAM therapies: acupuncture (n = 1), support groups (n = 2), hypnosis (n = 1), relaxation/imagery (n = 2), and herbal supplement/HESA-A (n = 1, but study was of low quality without control data). Seven studies reported immediate postintervention or short-term benefit of the following CAM interventions: acupuncture (n = 2), music (n = 1), herbal supplement/Ai-Tong-Ping (n = 1), massage (n = 1), and healing touch (n = 2). Four studies reported no benefit of CAM interventions (music, n = 2; massage, n = 2) in reducing cancer pain compared with a control arm. CONCLUSION There is paucity of multi-institutional RCTs evaluating CAM interventions for cancer pain with adequate power, duration, and sham control. Hypnosis, imagery, support groups, acupuncture, and healing touch seem promising, particularly in the short term, but none can be recommended because of a paucity of rigorous trials. Future research should focus on methodologically strong RCTs to determine potential efficacy of these CAM interventions.

Effect of massage therapy on pain, anxiety, and tension after cardiac surgery: A randomized study

Integrative therapies such as massage have gained support as interventions that improve the overall patient experience during hospitalization. Cardiac surgery patients undergo long procedures and commonly have postoperative back and shoulder pain, anxiety, and tension. Given the promising effects of massage therapy for alleviation of pain, tension, and anxiety, we studied the efficacy and feasibility of massage therapy delivered in the postoperative cardiovascular surgery setting. Patients were randomized to receive a massage or to have quiet relaxation time (control). In total, 113 patients completed the study (massage, n=62; control, n=51). Patients receiving massage therapy had significantly decreased pain, anxiety, and tension. Patients were highly satisfied with the intervention, and no major barriers to implementing massage therapy were identified. Massage therapy may be an important component of the healing experience for patients after cardiovascular surgery.

Use of Complementary and Alternative Medical Therapies by Patients Referred to a Fibromyalgia Treatment Program at a Tertiary Care Center

OBJECTIVE To evaluate the frequency and pattern of complementary and alternative medicine (CAM) use in patients referred to a fibromyalgia treatment program at a tertiary care center. PATIENTS AND METHODS Patients referred to the Mayo Fibromyalgia Treatment Program between February 2003 and July 2003 were invited on their initial visit to participate in a survey regarding CAM use during the previous 6 months. An 85-question survey that addressed different CAM domains was used. RESULTS Of the 304 patients invited to participate, 289 (95%) completed the survey (263 women and 26 men). Ninety-eight percent of the patients had used some type of CAM therapy during the previous 6 months. The 10 most frequently used CAM treatments were exercise for a specific medical problem (48%), spiritual healing (prayers) (45%), massage therapy (44%), chiropractic treatments (37%), vitamin C (35%), vitamin E (31%), magnesium (29%), vitamin B complex (25%), green tea (24%), and weight-loss programs (20%). CONCLUSION CAM use is common in patients referred to a fibromyalgia treatment program.

Effect of massage therapy on pain, anxiety, and tension in cardiac surgical patients: A pilot study

OBJECTIVES To assess the role of massage therapy in the cardiac surgery postoperative period. Specific aims included determining the difference in pain, anxiety, tension, and satisfaction scores of patients before and after massage compared with patients who received standard care. DESIGN A randomized controlled trial comparing outcomes before and after intervention in and across groups. SETTING Saint Marys Hospital, Mayo Clinic, Rochester, Minnesota. SUBJECTS Patients undergoing cardiovascular surgical procedures (coronary artery bypass grafting and/or valvular repair or replacement) (N=58). INTERVENTIONS Patients in the intervention group received a 20-minute session of massage therapy intervention between postoperative days 2 and 5. Patients in the control group received standard care and a 20-minute quiet time between postoperative days 2 and 5. OUTCOME MEASURES Linear Analogue Self-assessment scores for pain, anxiety, tension, and satisfaction. RESULTS Statistically and clinically significant decreases in pain, anxiety, and tension scores were observed for patients who received a 20-minute massage compared with those who received standard care. Patient feedback was markedly positive. CONCLUSIONS This pilot study showed that massage can be successfully incorporated into a busy cardiac surgical practice. These results suggest that massage may be an important therapy to consider for inclusion in the management of postoperative recovery of cardiovascular surgical patients.

A critical review of complementary therapies for cancer-related fatigue.

Purpose: To review the available literature on the use of complementary and alternative medicine (CAM) treatments for cancer-related fatigue with an aim to develop directions for future research. Methods: PubMed, EMBASE, CINAHL, PsycINFO, and SPORTDiscus were searched for relevant studies. Original clinical trials reporting on the use of CAM treatments for cancer-related fatigue were abstracted and critically reviewed. Results: CAM interventions tested for cancer-related fatigue include acupuncture, aromatherapy, adenosine triphosphate infusions, energy conservation and activity management, healing touch, hypnosis, lectinstandardized mistletoe extract, levocarnitine, massage, mindfulness-based stress reduction, polarity therapy, relaxation, sleep promotion, support group, and Tibetan yoga. Several of these interventions seem promising in initial studies. Conclusion: Currently, insufficient data exist to recommend any specific CAM modality for cancer-related fatigue. Therefore, potentially effective CAM interventions ready for further study in large, randomized clinical trials (eg, acupuncture, massage, levocarnitine, and the use of mistletoe) should be pursued. Other interventions should be tested in well-designed feasibility and phase II trials.

Reading the Tea Leaves: Anticarcinogenic Properties of (-)-Epigallocatechin-3-Gallate

Green tea is an extremely popular beverage worldwide. Derivatives of green tea, particularly (-)-epigallocatechin-3-gallate (EGCG), have been proposed to have anticarcinogenic properties based on preclinical, observational, and clinical trial data. To summarize, clarify, and extend current knowledge, we conducted a comprehensive search of the PubMed database and other secondary data sources, as appropriate, regarding the chemopreventive potential of EGCG. Apparently, EGCG functions as an antioxidant, preventing oxidative damage in healthy cells, but also as an antiangiogenic agent, preventing tumors from developing a blood supply needed to grow larger. Furthermore, EGCG may stimulate apoptosis in cancerous cells by negatively regulating the cell cycle to prevent continued division. Finally, EGCG exhibits antibacterial activity, which may be implicated in the prevention of gastric cancer. Although in vitro research of the anticarcinogenic properties of EGCG seems promising, many diverse and unknown factors may influence its in vivo activity in animal and human models. Some epidemiological studies suggest that green tea compounds could protect against cancer, but existing data are inconsistent, and limitations in study design hinder full interpretation and generalizability of the published observational findings. Several clinical trials with green tea derivatives are ongoing, and further research should help to clarify the clinical potential of EGCG for chemoprevention and/or chemotherapy applications.

VA national drug file reference terminology: A cross-institutional content coverage study

BACKGROUND Content coverage studies provide valuable information to potential users of terminologies. We detail the VA National Drug File Reference Terminologys (NDF-RT) ability to represent dictated medication list phrases from the Mayo Clinic. NDF-RT is a description logic-based resource created to support clinical operations at one of the largest healthcare providers in the US. METHODS Medication list phrases were extracted from dictated patient notes from the Mayo Clinic. Algorithmic mappings to NDF-RT using the SmartAccess Vocabulary Server (SAVS) were presented to two non-VA physicians. The physicians used a terminology browser to determine the accuracy of the algorithmic mapping and the content coverage of NDF-RT. RESULTS The 509 extracted documents on 300 patients contained 847 medication concepts in medication lists. NDF-RT covered 97.8% of concepts. Of the 18 phrases that NDF-RT did not represent, 10 were for OTCs and food supplements, 5 were for prescription medications, and 3 were missing synonyms. The SAVS engine properly mapped 773 of 810 phrases with an overall sensitivity (precision) was 95.4% and positive predictive value (recall) of 99.9%. CONCLUSIONS This study demonstrates that NDF-RT has more general utility than its initial design parameters dictated

Complementary and alternative medicine use among long‐term lymphoma survivors: A pilot study

No published survey has specifically addressed the beliefs, knowledge, and usage of complementary and alternative medicine (CAM) in long‐term (5–20 years) lymphoma survivors alone. In this pilot project, 95 subjects were randomly selected from a population of 2,475 long‐term lymphoma survivors and mailed a questionnaire. The median time from lymphoma diagnosis to completion of the questionnaire was 11 years (range 6–20). Overall, 68% (95% CI: 54–80%) of the long‐term lymphoma survivors reported that they have used CAM, a rate higher than the estimated usage rate reported for the general population The most commonly used modalities were chiropractic (39%, 95% CI: 27–53%) and massage therapy (21%, 95% CI: 12–34%). Less than 10% used meditation (5%, 95% CI: 1–15%) and relaxation (7%, 95% CI: 2–17%). In terms of common herbal usage, 5% (95% CI: 1–15%) had used St. Johns Wort and 7% (95% CI: 2–17%) had used shark cartilage. Although none of the patients reported that CAM usage was directed specifically towards treating their lymphoma, 4% (95% CI: 0–12%) of patients reported that CAM could cure cancer, and 14% (95% CI: 6–26%) reported that CAM could increase their feeling of control over their health. This pilot study suggests that long‐term lymphoma survivors appear to use CAM at a rate higher than the general population. The use of potential agents of risk by the survivors and the lack of access to potentially beneficial modalities highlights the need for further study of CAM in this population. Am. J.

The introduction of a diagnostic decision support system (DXplain™) into the workflow of a teaching hospital service can decrease the cost of service for diagnostically challenging Diagnostic Related Groups (DRGs)

BACKGROUND In an era of short inpatient stays, residents may overlook relevant elements of the differential diagnosis as they try to evaluate and treat patients. However, if a residents first principal diagnosis is wrong, the patients appropriate evaluation and treatment may take longer, cost more, and lead to worse outcomes. A diagnostic decision support system may lead to the generation of a broader differential diagnosis that more often includes the correct diagnosis, permitting a shorter, more effective, and less costly hospital stay. METHODS We provided residents on General Medicine services access to DXplain, an established computer-based diagnostic decision support system, for 6 months. We compared charges and cost of service for diagnostically challenging cases seen during the fourth through sixth month of access to DXplain (intervention period) to control cases seen in the 6 months before the system was made available. RESULTS 564 cases were identified as diagnostically challenging by our criteria during the intervention period along with 1173 cases during the control period. Total charges were
