Acupuncture compared with placebo acupuncture in radiotherapy-induced nausea--a randomized controlled study

Effect of Adding Electroacupuncture to Standard Triple Antiemetic Therapy on Chemotherapy-Induced Nausea and Vomiting: A Randomized Controlled Clinical Trial

PURPOSE

We aim to determine the effectiveness of adding electroacupuncture to standard triple antiemetic therapy for treating chemotherapy-induced nausea and vomiting (CINV).

METHODS

From March 2022 to December 2023, a randomized, blind, sham-controlled trial conducted across six Chinese hospitals investigated patients with breast cancer undergoing highly emetogenic chemotherapy (HEC). Patients were randomly assigned to either true electroacupuncture (n = 120) or sham electroacupuncture (n = 119) groups, with both groups receiving standard triple antiemetic therapy. The primary end point was the proportion of complete protection (no vomiting, no need for rescue treatment, and no significant nausea, as evaluated using the visual analog scale [VAS]) within 120 hours after receiving HEC.

RESULTS

Among 239 randomly assigned patients, 235 (98.3%) completed the trial. In the full analysis set, compared with the sham electroacupuncture group, the true electroacupuncture group demonstrated a significant increase in the complete protection rate from 34.5% to 52.9% (P = .004). Additionally, true electroacupuncture also showed enhanced total control (4.3% v 13.4%; P = .014), no significant nausea (37.9% v 58.8%; P = .001), no nausea (4.3% v 13.4%; P = .014), and nausea VAS score = 0 mm (4.3% v 12.6%; P = .023). However, the occurrence of no vomiting in the overall stage was similar (76.7% v 73.9%; P = .622) in both groups. Post hoc exploratory analysis showed a significantly higher rate of complete protection during the delayed stage in the true electroacupuncture group compared with the sham electroacupuncture group, with no significant difference observed during the acute stage.

CONCLUSION

Adding true electroacupuncture to standard triple antiemetic therapy significantly enhances the efficacy of CINV treatment in patients with breast cancer receiving HEC.

Brain-computer interface relieves chronic chemotherapy-induced peripheral neuropathy: A randomized, double-blind, placebo-controlled trial

BACKGROUND

Chemotherapy-induced peripheral neuropathy (CIPN) includes negative sensations that remain a major chronic problem for cancer survivors. Previous research demonstrated that neurofeedback (a closed-loop brain-computer interface [BCI]) was effective at treating CIPN versus a waitlist control (WLC). The authors' a priori hypothesis was that BCI would be superior to placebo feedback (placebo control [PLC]) and to WLC in alleviating CIPN and that changes in brain activity would predict symptom report.

METHODS

Randomization to one of three conditions occurred between November 2014 and November 2018. Breast cancer survivors no longer in treatment were assessed at baseline, at the end of 20 treatment sessions, and 1 month later. Auditory and visual rewards were given over 20 sessions based on each patient's ability to modify their own electroencephalographic signals. The Pain Quality Assessment Scale (PQAS) at the end of treatment was the primary outcome, and changes in electroencephalographic signals and 1-month data also were examined.

RESULTS

The BCI and PLC groups reported significant symptom reduction. The BCI group demonstrated larger effect size differences from the WLC group than the PLC group (mean change score: BCI vs. WLC, -2.60 vs. 0.38; 95% confidence interval, -3.67, -1.46 [p = .000; effect size, 1.07]; PLC, -2.26; 95% confidence interval, -3.33, -1.19 [p = .001 vs. WLC; effect size, 0.9]). At 1 month, symptoms continued to improve only for the BCI group. Targeted brain changes at the end of treatment predicted symptoms at 1 month for the BCI group only.

CONCLUSIONS

BCI is a promising treatment for CIPN and may have a longer lasting effect than placebo (nonspecific BCI), which is an important consideration for long-term symptom relief. Although scientifically interesting, the ability to separate real from placebo treatment may not be as important as understanding the placebo effects differently from effects of the intervention.

PLAIN LANGUAGE SUMMARY

Chemotherapy-induced nerve pain (neuropathy) can be disabling for cancer survivors; however, the way symptoms are felt depends on how the brain interprets the signals from nerves in the body. We determined that the perception of neuropathy can be changed by working directly with the brain. Survivors in our trial played 20 sessions of a type of video game that was designed to change the way the brain processed sensation and movement. In this, our second trial, we again observed significant improvement in symptoms that lasted after the treatment was complete.

A single-item Expectancy Measure's Validity, Reliability, and Responsiveness to Detect Changes in Clinical Efficacy Studies of Integrative Cancer Therapies: A Methodology Study

BACKGROUND

Expectations may modify outcomes. However, studies often fail to measure expectations. This raises the need for a brief valid and reliable expectancy measure.

OBJECTIVES

To study treatment expectations in individuals entering acupuncture or rest, validity and test re-test reliability of a single-item expectancy measure graded on a category scale, a Numeric Rating Scale (NRS) and a Visual Analog Scale (VAS), and to identify psychometric differences between the scales.

METHOD

In this methodology study, treatment expectations were measured in 363 participants before they received acupuncture (genuine traditional penetrating or non-penetrating telescopic sham acupuncture, n = 239, 98%, responded) or a control treatment involving just rest (n = 120, 100%, responded), aimed to improve level of relaxation. A treatment expectancy measure, graded on a five-grade category scale, an eight-grade NRS and a 100 mm VAS, was tested for test re-test reliability. Level of expectation and relaxation was measured at baseline, pre- and post-therapy (n = 729 expectancy measurements).

RESULTS

The participants scheduled for acupuncture or rest believed moderately (Inter Quartile Range, IQR, moderately-much) and much (IQR moderately-much) the treatment to be effective. The Intra-Class Correlation coefficient versus Kappa coefficient between test and re-test was .868/.868 for the category scale, .820/.820 for the NRS, and .856/.854 for the VAS. The middle step "Believe moderately the treatment to be effective" was equivalent with median 4 (IQR, 3-4) on NRS and median 52 mm (IQR 42-52) on VAS. The response rates were 708 (97%) on the category scale, 707 (97%) on the NRS, and 703 (96%) on the VAS. All three scales discriminated that pre-therapy expectations were more positive in the individuals who reported an improvement in relaxation level (P < .001-.003). The VAS presented higher responsiveness to detect expectancy changes over time (71% increased expectation), compared to the NRS (52% increased) and the category scale (12% increased), P < .001.

CONCLUSIONS

Individuals entering acupuncture, or a control intervention, presented positive treatment expectations, and the expectancy measure presented satisfactory reliability, validity, high response rates, sensitiveness, and responsiveness. Integrative cancer therapy researchers who want to control for expectancy-related bias in clinical trials should consider measuring expectation using the single-item expectancy measure.

2023 Updated MASCC/ESMO Consensus Recommendations: prevention of radiotherapy- and chemoradiotherapy-induced nausea and vomiting

PURPOSE

Radiotherapy and chemoradiotherapy-induced nausea and vomiting (RINV and C-RINV) are common and distressing, and there is a need for guidance for clinicians to provide up to date optimal antiemetic prophylaxis and treatment. Through a comprehensive review of the literature concerning RINV and C-RINV, this manuscript aims to update the evidence for antiemetic prophylaxis and rescue therapy and provide a new edition of recommendations for the MASCC/ESMO antiemetic guidelines for RINV and C-RINV.

METHODS

A systematic review of the literature including data published from May 1, 2015, to January 31, 2023, was performed. All authors assessed the literature.

RESULTS

The searches yielded 343 references; 37 met criteria for full article review, and 20 were ultimately retained. Only one randomized study in chemoradiation had the impact to provide new recommendations for the antiemetic guideline. Based on expert consensus, it was decided to change the recommendation for the "low emetic risk" category from "prophylaxis or rescue" to "rescue" only, while the drugs of choice remain unchanged.

CONCLUSION

As for the previous guideline, the serotonin receptor antagonists are still the cornerstone in antiemetic prophylaxis of nausea and vomiting induced by high and moderate emetic risk radiotherapy. The guideline update provides new recommendation for the management of C-RINV for radiotherapy and concomitant weekly cisplatin. To avoid overtreatment, antiemetic prophylaxis is no longer recommended for the "low emetic risk" category.

Physical, Leisure, and Daily Living Activities in Patients Before, During, and After Radiotherapy for Cancer: Which Patients Need Support in Activities?

BACKGROUND

Avoiding inactivity and staying active during cancer therapy have great health effects.

OBJECTIVE

The aims of this study were to describe level of daily, leisure, and physical activities before, during, and after radiotherapy and to investigate whether patients who had not restored activity level after radiotherapy differed from patients who had restored activity level regarding different characteristics.

METHODS

In this descriptive longitudinal study, 196 patients undergoing pelvic-abdominal radiotherapy reported their activity level at baseline, weekly during radiotherapy, and at 1 month after radiotherapy.

RESULTS

Patients decreased activity level during radiotherapy (P < .001 for all activities): physical activity (34% of patients decreased level), walking (26%), leisure activities (44%), social activities (15%), housework (34%), shopping (28%), and activities in general (28%). Almost half (47%) had not restored activity level after radiotherapy. Patients with colorectal cancer, older than 65 years, who had less education than university, and high capacity in overall daily activities at baseline were more likely than other patients not to restore activity level after radiotherapy. The patients not restoring their activity level after radiotherapy were more likely than others to experience anxious mood (P = .016), depressed mood (P = .003), and poor quality of life (P = .003) after radiotherapy.

CONCLUSION

Patients' activity level decreased during radiotherapy, and almost half of patients did not restore activity level after radiotherapy.

IMPLICATIONS FOR PRACTICE

Given that restored activity level after radiotherapy was less common in certain subgroups and that patients who restored activity level experienced better quality of life and less frequent anxious and depressed mood, cancer nursing professionals should consider supporting these subgroups of patients in performing activities.

Efficacy of auricular plaster therapy for sleep disorders in preschool children with autism spectrum disorders: Study protocol for a randomized controlled trial

Background

Children with autism spectrum disorders (ASDs) suffer from sleep disorders to a considerable degree; however, there is no safe and effective treatment available in clinical practice. The objective of the trial is to assess the clinical effectiveness of auricular plaster therapy (APT) in treating sleep disorders in children with ASD.

Method

This is a single-center, patient-assessor blind, randomized controlled trial. A total of 44 preschool children with sleep disorders with ASD will be included in this study. Eligible participants will be randomly assigned to either the auricular plaster group or the sham auricular plaster group in a 1:1 ratio. Participants in the different groups will receive APT or sham APT, respectively, for a total of 30 sessions over 30 days. The primary outcome includes the Children's Sleep Habits Questionnaire (CSHQ), while secondary outcomes include the Autism Behavior Checklist (ABC) and polysomnography (PSG) for total sleep time, sleep latency, awakening duration, and sleep structures. The CSHQ and ABC will be assessed at baseline, 10, 20, 30, 60, 90, and 120 days after randomization, whereas PSG will be assessed at baseline and 30 days after randomization. The follow-up period will be scheduled to be 60, 90, and 120 days after randomization.

Discussion

The results of this study may provide evidence of the efficacy of APT, as well as offer new alternatives for the treatment of sleep disorders in children with ASD.

Central correlates of placebo effects in nausea differ between men and women

INTRODUCTION

Despite growing evidence validating placebo effects in nausea, little is known about the underlying cortical mechanisms in women and men. Therefore, the present study examined sex differences and electroencephalography (EEG) characteristics of the placebo effect on nausea.

METHODS

On 2 consecutive days, 90 healthy subjects (45 females) were exposed to a nauseating visual stimulus. Nausea was continuously rated on an 11-point numeric rating scale, and 32 EEG channels were recorded. On day 2, subjects were randomly allocated to either placebo treatment or no treatment: the placebo group received sham acupuncture, whereas the control group did not receive any intervention.

RESULTS

In contrast to the control group, both sexes in the placebo group showed reduced signs for anticipatory nausea in the EEG, indexed by increased frontal lobe and anterior cingulate activity. Among women, the improvement in perceived nausea in the placebo group was accompanied by decreased activation in the parietal, frontal, and temporal lobes. In contrast, the placebo-related improvement of perceived nausea in men was accompanied by increased activation in the limbic and sublobar (insular) lobes.

CONCLUSION

Activation of the parietal lobe in women during the placebo intervention may reflect altered afferent activity from gastric mechanoreceptors during nausea-induced tachyarrhythmia, whereas in men, altered interoceptive signals in the insular cortex might play a role. Thus, the results suggest different cerebral mechanisms underlying the placebo effects in men and women, which could have implications for the treatment of nausea.

Cross-Cultural Brain Activity Differences Between True and Sham Acupuncture for Xerostomia During Head and Neck Cancer Radiotherapy

Background:

A prior phase III, multicenter (United States and China), clinical trial found true acupuncture (TA) resulted in lower xerostomia scores 12 months after radiotherapy than that of a standard care control group. This small pilot study examined brain function changes comparing TA to sham acupuncture (SA) in US and Fudan patients undergoing head and neck radiotherapy.

Methods:

To determine cerebral activity during TA versus SA acupuncture, patients underwent electroencephalogram evaluation (EEG) immediately prior, during and after both conditions. Acupuncture occurred during weeks 3 to 5 of radiotherapy, with patients receiving either TA or SA, followed 2 to 3 days later by the other treatment in a counterbalanced manner.

Results:

In the TA minus SA condition (N = 14 Fudan; N = 13 US), most changes were in the delta (0.5-3.5 Hz) and alpha (8-12 Hz) bandwidths. Delta was present in the frontal gyrus and parahippocampal gyrus. Alpha was present in the anterior and posterior cingulate, lingual gyrus, amygdala, precuneus, medial frontal gyrus, fusiform gyrus, and superior frontal gyrus. Maximal cortical differences in the Fudan cohort between TA and SA were in areas previously shown to be associated with (TA). In the US cohort, maximal differences between TA and SA were associated with areas which are usually decreased in TA conditions.

Conclusions:

There were distinct differences in brain function between those receiving TA and SA and there were clear differences between cultures, helping to explain the lack of placebo effect in the Fudan participants and strong placebo effect in the US patients.

Safety of acupuncture in oncology: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Acupuncture is frequently used to treat the side effects of cancer treatment, but the safety of this intervention remains uncertain. The current meta-analysis was conducted to assess the safety of acupuncture in oncological patients.

METHODS

The PubMed, Cochrane Central Register of Controlled Trials, and Scopus databases were searched from their inception to August 7, 2020. Randomized controlled trials in oncological patients comparing invasive acupuncture with sham acupuncture, treatment as usual (TAU), or any other active control were eligible. Two reviewers independently extracted data on study characteristics and adverse events (AEs). Risk of bias was assessed using the Cochrane Risk of Bias Tool.

RESULTS

Of 4590 screened articles, 65 were included in the analyses. The authors observed that acupuncture was not associated an with increased risk of intervention-related AEs, nonserious AEs, serious AEs, or dropout because of AEs compared with sham acupuncture and an active control. Compared with TAU, acupuncture was not associated with an increased risk of intervention-related AEs, serious AEs, or drop out because of AEs but was associated with an increased risk for nonserious AEs (odds ratio, 3.94; 95% confidence interval, 1.16-13.35; P = .03). However, the increased risk of nonserious AEs compared with TAU was not robust against selection bias. The meta-analyses may have been biased because of the insufficient reporting of AEs in the original randomized controlled trials.

CONCLUSIONS

The current review indicates that acupuncture is as safe as sham acupuncture and active controls in oncological patients. The authors recommend researchers heed the CONSORT (Consolidated Standards of Reporting Trials) safety and harm extension for reporting to capture the side effects and better investigate the risk profile of acupuncture in oncology.

LAY SUMMARY

According to this analysis, acupuncture is a safe therapy for the treatment of patients with cancer. Acupuncture seems to be safe compared with sham acupuncture and active controls.

Implementation of Acupuncture in Routine Oncology Care: A Comparison of Physicians’, Nurses’, Physiotherapists’ and Acupuncturists’ Practice and Beliefs

Background:

It is important to investigate beliefs in acupuncture in professionals because professionals’ expectations may affect treatment outcomes.

Aim:

To document the type, number, and education of professionals practicing acupuncture. Further, to compare beliefs about the effectiveness of acupuncture for common cancer related symptoms in the different types of professionals.

Methods:

This cross-sectional study employed a questionnaire on practice and beliefs regarding acupuncture effects for symptoms that commonly occur in patients treated within oncology care settings. The respondents (n = 555) consisted of oncology professionals that is, physicians (n = 133), nurses (n = 172), and physiotherapists (n = 117). Additional respondents consisted of acupuncturists (n = 133), working outside approved health care.

Results:

Of the respondents, acupuncture was practiced by 4% of the physicians, 6% of the nurses, 58% of the physiotherapists, and 90% of the acupuncturists. The professionals believed acupuncture to be effective for pain (of the physicians, nurses, physiotherapists, and acupuncturists, 94%, 98%, 89%, and 99% respectively believed in the effectiveness), chemotherapy-induced nausea (corresponding figures: 74%, 89%, 89%, and 93%), and vasomotor symptoms (corresponding figures: 71%, 81%, 80%, and 97%). The physicians believed acupuncture to be effective in a mean of 5 symptoms, nurses in 6 symptoms, physiotherapists in 6 symptoms, and acupuncturists in 10 symptoms ( P < .001).

Conclusions:

Since the professionals varied substantially regarding practice, education and beliefs in acupuncture, oncology clinics may consider delivering patient preferred acupuncture according to evidence-informed guidelines rather than on varying preferences among the professionals, since professionals’ treatment expectations may modify treatment outcomes.

Effect of acupuncture at Zusanli (ST36) point on antral contraction function under ultrasound guidance: study protocol of a randomized controlled trial

BACKGROUND

Although the relationship between deqi sensations and curative effect has always been controversial, deqi sensations has been regarded as the key indicator of clinical efficacy of acupuncture therapy. There is little evidence for standardization or visualization of the mechanism of acupuncture's therapeutic effect. This trial aims to evaluate the effect of needling at Zusanli (ST36) on antral contraction function as visualized by ultrasound.

METHODS

This is a two-arm, single-blind, randomized, controlled trial. A total of 116 acupuncture-naïve healthy subjects will be randomly allocated to the acupuncture group or sham acupuncture group in a 1:1 ratio. Participants in the acupuncture group will receive manual acupuncture at Zusanli (ST36) with the needling depth at crural interosseous membrane. Those in the sham acupuncture group will be given penetrating needling depth at the superficial fascia layer. The primary outcome will be the changes in antral contraction frequency (ACF) before and after acupuncture. The secondary outcomes will be the changes in the thermal infrared spectrum of gastric area skin, the antral contraction amplitude (ACA), the antral movement index (AMI), and the scores on the Chinese version of Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS). The adverse events will be evaluated and recorded in detail.

DISCUSSION

This study may provide visual and objective evidence regarding the safety and efficacy of manual acupuncture at Zusanli (ST36). In addition, the results of this study will help to identify the role of Zusanli (ST36)in the inducing deqi.

Sleep During Pelvic-Abdominal Radiotherapy for Cancer: A Longitudinal Study With Special Attention to Sleep in Relation to Nausea and Quality of Life

BACKGROUND

Poor sleep, nausea, psychological distress, and a lowered quality of life are common during radiotherapy for cancer. There is a lack of studies on the relationship between radiotherapy-induced nausea and sleep. This longitudinal study analyzes data from 196 patients who underwent pelvic-abdominal radiotherapy for cancer.

OBJECTIVE

The aim of this study was to investigate sleep parameters weekly before, during, and after radiotherapy in relation to nausea and other patient characteristics, clinical characteristics, psychological distress, and quality of life.

METHODS

Patients (n = 196, 84% women; mean age, 63 years; 68% had gynecological tumor, 28% had colorectal tumor, and 4% had other tumors) longitudinally answered questionnaires before, during, and after their radiotherapy over the abdominal and pelvic fields.

RESULTS

Poor sleep was experienced by 30% of the participants, and sleep (quality and difficulty falling asleep) improved during and after treatment compared with baseline. Experiencing nausea during treatment was associated with worse sleep quality during radiotherapy. Baseline anxiety was associated with worse sleep quality before, during, and after treatment. Poor sleep was associated with worse quality of life.

CONCLUSION

Nausea, more than a number of other variables, is a possible predictor of poor sleep in patients during radiotherapy for cancer.

IMPLICATIONS FOR PRACTICE

The results indicate that effectively managing nausea may be important for sleep quality, and possibly quality of life, in patients undergoing radiotherapy for cancer. More research is needed before recommendations for practice can be made.

Frequent Stools Were Related to Reduced Quality of Life and Capacity in Daily Activities: Weekly Observations During and After Pelvic or Abdominal Radiotherapy

BACKGROUND

Greater knowledge regarding stool frequency and infrequency during pelvic and abdominal irradiation is needed to accurately identify patients at risk of either.

OBJECTIVE

To describe occurrence of frequent and infrequent stools during pelvic-abdominal radiotherapy, and to compare quality of life (QoL) and activities of daily living (ADLs) of those patients experiencing frequent stools with those of patients experiencing infrequent stools.

METHODS

Longitudinally during radiotherapy, 193 patients (64% had gynecological tumors) documented stool frequency, medications, and QoL using the Functional Assessment of Cancer Therapy-General.

RESULTS

Fifty (26%) experienced frequent stools (≥28 stools a week), and 17 (9%) experienced infrequent stools (<3 stools a week). The frequency of stools and the consumption of medication for diarrhea were highest the last week of the radiotherapy period (50% had ≥49 stools a week, and 50% could not even define the number of stools). Thirty-seven of the patients experiencing frequent stools used antidiarrhea medications. Patients with frequent stools experienced lower QoL (P = .035) and capacity in ADLs (P = .023) compared with patients not experiencing frequent stools.

CONCLUSIONS

A fourth of patients irradiated over pelvic or abdominal fields experienced frequent stools, defined as moderate to severe diarrhea, and those patients experienced lower QoL and capacity in ADLs compared with patients who did not experience frequent stools. Infrequent stools were rarely experienced.

IMPLICATIONS FOR PRACTICE

Cancer nursing professionals should deliver evidence-based strategies to prevent frequent stools and treat frequent stools as an approach to lower the risk of impaired capacity in daily living and worsened QoL.

Methodology Aspects of Nausea Measuring During Pelvic Radiotherapy: Daily Nausea Measuring Is Successful to Identify Patients Experiencing Nausea

BACKGROUND

Nausea seems underreported during pelvic radiotherapy.

OBJECTIVE

The aims of this study were to investigate if a 5-week recall measure of nausea covering the entire radiotherapy period was comparable with accumulated daily nausea measurements and to investigate if the measuring method affected potential difference in quality of life (QoL) between nauseated patients and patients free from nausea.

METHODS

This longitudinal methodology study covered 200 patients (mean age, 64 years; 84% women; 69% had gynecological cancer). The patients graded QoL (Functional Assessment of Cancer Therapy-General). They registered nausea daily and at a 5-week recall at the end of radiotherapy.

RESULTS

The nausea-intensity category scale and visual analog scale correlated well (Spearman correlation coefficient = 0.622). According to the 5-week recall, 57 of 157 answering patients (36%) experienced nausea during the radiotherapy period. Using the daily nausea measurements, 94 of 157 patients (60%) experienced nausea (relative risk, 1.65; 95% confidence interval, 1.29-2.10). Of these 94 nauseated patients, 39 (42%) did not report nausea using the 5-week recall. The nauseated patients experienced worse QoL (physical/functional subscores) than patients free from nausea whether nausea was registered daily or at the 5-week recall.

CONCLUSIONS

Almost half, 42%, of the patients who experienced nausea according to daily nausea measurements did not report having had nausea according to the 5-week recall. Nauseated patients graded worse QoL than patients who were free from nausea.

IMPLICATIONS FOR PRACTICE

Nursing professionals should measure nausea repeatedly to identify patients at risk of nausea and worsened QoL, to be able to deliver evidence-based antiemetic treatment strategies.

Complementary and Alternative Medicine in Radiotherapy: A Comprehensive Review

Complementary and alternative medicine (CAM) approaches are widely used by patients throughout a broad range of medical fields and diseases, and often self-administered by patients without the involvement of physicians or other members of the health care team. CAM use is well documented in cancer and chronic illnesses, and emerging data in radiation oncology show CAM usage of 26% to 97% in radiation therapy patients. No information is, however, available on CAM usage in radiology and in the imaging procedure fields. This article reviews the fundamental principles and the experience with the wide spectrum of CAM in radiation oncology-a field that shares many parallels with radiology, such as prevalence of imaging, procedural requirements, and cooperation demanded from patients.CAM is defined as "approaches and practices that are typically not part of conventional medical care," and includes the use of mind- and body-based practices (eg, meditation, massage, acupuncture), natural products (eg, herbs, vitamins, minerals), and other interventions. Supplements are used frequently to alleviate side effects of therapy and promote overall well-being. Specifically, the mindfulness/meditation approaches of CAM are known to reduce anxiety and enhance physical and emotional wellbeing in patients with chronic diseases, such as cancer or neurologic diseases, through physiological, psychological, and perhaps placebo mechanisms. Such patients often require repetitive and invasive imaging examinations or procedures, such as for cancer treatment, cancer surveillance/follow-up, or monitoring of chronic diseases, for example, surveillance MRI in multiple sclerosis. Such parallels suggest that the vastly understudied area of CAMs deserve further investigation in both the radiation oncology and the imaging fields. Further research on CAM is needed to develop refined recommendations and national/and international guidelines on its use.

Clinical evidence of acupuncture and related therapy in patients with cancer-pain: A protocol for systematic review and meta-analysis

BACKGROUND

Cancer pain (CP) is one of the common complications of cancer. During the treatment, oral medication, radiotherapy and chemotherapy bring certain adverse reactions to patients with CP; a safe way to treat this disease is necessary. Acupuncture and related therapies for CP with few side effects have been gradually accepted. But at present the evidence is insufficient, the related research is not thorough enough. The purpose of this study was to investigate the efficacy and safety of acupuncture and related therapies for CP.

METHODS

The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines were used to design this protocol. The final study will also be conducted under the PRISMA guidelines for systematic reviews and meta-analysis. An electronic search will be conducted in Medline, Embase, and the Cochrane Central Register of Controlled Trials databases through January 2020. The search will be conducted in English. Risk of bias will be assessed by the Cochrane Collaboration tool and the collected evidence will be nar-ratively synthesized. We will also perform a meta-analysis to pool estimates from studies considered to be homogenous. Subgroup analyses will be based on intervention or overall bias. The strength of evidence will be evaluated by the Grading of Recommendations, Assessment, Development and Evaluation scale.

RESULTS

This systematic review will summarize high quality clinical evidence to assess and appraise the effectiveness and safety of acupuncture and related therapies for CP patients.

CONCLUSION

The meta-analysis will assess evidence from randomized controlled trials of acupuncture and related therapies and CP types.

Does acupressure help reduce nausea and vomiting in palliative care patients? A double blind randomised controlled trial

INTRODUCTION

Nausea and vomiting are common symptoms for patients with advanced cancer. While there is evidence for acupuncture point stimulation for treatment of these symptoms for patients having anticancer treatment, there is little for when they are not related to such treatment.

OBJECTIVE

To determine whether acupressure at the pericardium 6 site can help in the treatment of nausea and vomiting suffered by palliative care patients with advanced cancer.

MATERIALS AND METHODS

Double blind randomised controlled trial-active versus placebo acupressure wristbands. In-patients with advanced cancer in two specialist palliative care units who fitted either or both of the following criteria were approached: Nausea that was at least moderate; Vomiting daily on average for the prior 3 days.

RESULTS

57 patients were randomised to have either active or placebo acupressure wristbands. There was no difference in any of the outcome measures between the two groups: change from baseline number of vomits; Visual Analogue Scale for 'did acupressure wristbands help you to feel better?'; total number of as needed doses of antiemetic medication; need for escalation of antiemetics.

CONCLUSIONS

In contrast to a previously published feasibility study, active acupressure wristbands were no better than placebo for specialist palliative care in-patients with advanced cancer and nausea and vomiting.

Treatment expectations seem to affect bowel health when using acupuncture during radiotherapy for cancer: Secondary outcomes from a clinical randomized sham-controlled trial

OBJECTIVE

To investigate if frequent stools ("diarrhoea"), infrequent stools ("constipation"), capacity in daily activities and Quality of Life (QoL) differed between patients treated with verum or sham acupuncture, and if patients with more positive treatment expectations differed regarding frequent stools and infrequent stools from patients with less positive treatment expectations.

METHODS

In this randomized sham controlled trial, 200 patients received verum traditional penetrating acupuncture or sham acupuncture using a telescopic non-penetrating sham-needle 2-3 times a week during abdominal-pelvic radiotherapy (12 needling sessions during median 5 radiotherapy weeks). The patients registered stool frequency once a week, and registered capacity in daily activities and QoL at the start and end of radiotherapy, and at a one-month follow-up.

RESULTS

In the verum acupuncture group, 29 of 96 answering patients (30 %) experienced frequent stools and 7 (7 %) experienced infrequent stools at least one week of radiotherapy. In the sham acupuncture group, 21 of 97 (22 %) experienced frequent stools (p = 0.175) and 10 (10 %) experienced infrequent stools (p = 0.613). Patients with low treatment expectancy were more likely than other patients to experience frequent stools (60 % versus 26 %, p = 0.014) but not to experience infrequent stools (25 % versus 12 %, p = 0.334).

CONCLUSION

Penetrating acupuncture was not effective for frequent stools or for infrequent stools and did not improve capacity in daily activities or QoL in patients undergoing pelvic-abdominal irradiation for cancer more than non-penetrating acupuncture. Since patients with low acupuncture treatment expectations were more likely to experience frequent stools compared to other patients, non-specific treatment effects warrant further studies.

Observing the Implementation of Shared Decision-making in Routine Radiotherapy Cancer Nursing: An Explorative Longitudinal Questionnaire Study

BACKGROUND

Healthcare professionals have driven decision-making in the past. However, shared decision-making has the potential to increase quality of care.

OBJECTIVE

To determine to what degree patients undergoing routine pelvic radiotherapy care perceive decision-making as being shared between patient and healthcare professionals.

METHODS

This exploratory longitudinal study covered 193 patients undergoing pelvic radiotherapy, mostly women (n = 161 [84%]) treated for a gynecological (n = 132 [68%]) or colorectal (n = 54 [28%]) cancer. We collected data regarding self-perceived level of shared decision-making at the start of radiotherapy and quality of life (QoL) (91%-95% response rate per week) during the radiotherapy period.

RESULTS

The patients reported that they shared the decision-making with the healthcare professionals much (n = 137 [71%]), moderately (n = 33 [17%]), a little (n = 12 [6%]), or not at all (n = 11 [6%]). Male patients (P = .048), patients who did not live with their partner (P = .034), patients with higher education (P = .043), and patients with low functional capacity (P = .018) perceived lower levels of shared decision-making. A higher level of shared decision-making was related to higher QoL at baseline and during the first to third weeks of radiotherapy (P ranged from .001 to .044).

CONCLUSIONS

Almost 9 of 10 patients reported that they shared the decision-making moderately or much with the healthcare professionals. The study identified subgroups perceiving lower levels of shared decision-making and found that a higher level of shared decision-making was related to better QoL.

IMPLICATIONS

Healthcare professionals may need to pay extra attention to patients who may perceive that they share decision-making to a low extent.

Acupuncture for radiotherapy-induced nausea and vomiting: A systematic review protocol

BACKGROUND

Assessing the effectiveness and safety of acupuncture therapy for treating patients with radiotherapy-induced nausea and vomiting (RINV) is the main purpose of this systematic review protocol.

METHODS

The following electronic databases will be searched from inception to Sep 2019: Cochrane Central Register of Controlled Trials, PubMed, Web of Science, EMBASE, China National Knowledge Infrastructure, Traditional Chinese Medicine, Chinese Biomedical Literature Database, Wan-Fang Database, and Chinese Scientific Journal Database. All published randomized controlled trials in English or Chinese related to acupuncture for RINV will be included. The primary outcome is the severity and frequency of RINV during radiotherapy. The secondary outcomes is the physical condition and quality of life after radiotherapy. Two reviewers will conduct the study selection, data extraction, and assessment independently. The assessment of risk of bias and data synthesis will be conducted with Review Manager Software V.5.2.

RESULTS

The results will provide a high-quality synthesis of current evidence for researchers in this subject area.

CONCLUSION

The conclusion of our study will provide evidence to judge whether acupuncture is an effective intervention for patients suffered from RINV.

Complementary medicine in radiation oncology : German health care professionals' current qualifications and therapeutic methods

INTRODUCTION

Recently, complementary and alternative medicine (CAM) has moved more into the focus, and cancer societies such as the German Cancer Society (Deutsche Krebsgesellschaft, DKG) have established working groups to develop a guideline for CAM. The present work aims to evaluate the acceptance of CAM in the whole radiation oncology community.

METHODS

We conducted an online survey on CAM and sent the modified questionnaire that was successfully distributed to all members of the Research Group on Gynecological Oncology (Arbeitsgemeinschaft Gynakologische Onkologie, AGO) of the DKG in 2014 to the members of the German Society of Radiation Oncology (Deutsche Gesellschaft für Radioonkologie und Strahlentherapie, DEGRO). The survey consisted of 17 questions regarding personal information and current CAM guidelines within the workplace/clinic.

RESULTS

A total of 143 members participated. Of these, 12% had some CAM qualification. For hematological cancer in 35% and in up to 76% for breast cancer, CAM treatment is offered in German radiation oncology facilities, mainly due to fatigue symptoms. CAM is part of routine treatment in 32.2%, 22.0% are planning to incorporate it. Most physicians advise patients to partake in sports activities and recommend dietary supplements and nutritional counseling. The cost of CAM treatment is fully covered in 9.8% of all participating facilities.

CONCLUSION

Today, CAM is integrated into cancer care; however, skepticism regarding its effect still exists. Evidence-based results must be generated to convince physicians of the effectiveness of CAM methods. CAM qualifications must be included in physicians' training to improve their understanding and counseling regarding CAM options in cancer care.

Understanding rationales for acupuncture treated individuals' beliefs in acupuncture effects, to be able to maximize therapeutic results: A qualitative analysis

OBJECTIVE

To investigate how individuals expressed rationales for their beliefs regarding efficacy of acupuncture.

METHODS

Qualitative data from participants of two different randomized sham-controlled trials, of relaxing (non-cancer volunteers of the general population) or antiemetic (patients with cancer undergoing radiotherapy) effects of acupuncture was analyzed. Participants (n = 441) received genuine (n = 120 and n = 100) or sham (n = 121 and n = 100) (telescopic blunt sham-needle) relaxing or antiemetic acupuncture. The participants (n = 428; 97% response rate) expressed their belief regarding the efficacy of acupuncture, and n = 264 delivered qualitative rationales for their belief, analyzed using qualitative content analysis.

RESULTS

Of the 428 participants, 35 (8%) believed entirely that the acupuncture was effective, 209 (49%) believed much, 136 (32%) believed moderately, 39 (9%) believed a little, and 9 (2%) did not believe that the acupuncture was effective. Five categories and seven subcategories represented the meaning units of the central message of the rationales for the treatment belief. Participants with positive beliefs (believed entirely/much, n = 244) presented rationales related to: "Experienced positive effects", "Knowledge regarding effect-mechanisms of acupuncture", and "General trustworthiness of acupuncture". Participants with more negative beliefs (believed a little or not, n = 48) presented rationales related to: "Lack of feasibility of the acupuncture", "Varying effects", and "The effect is individual, not available for everybody".

CONCLUSION

In order to strengthen acupuncture treated patients' beliefs in the efficacy of acupuncture during clinical practice or research, acupuncture therapists may consider emphasizing these aspects in the therapeutic situation.

Type and frequency of side effects during PC6 acupuncture: observations from therapists and patients participating in clinical efficacy trials of acupuncture

BACKGROUND

Many therapists practise PC6 acupuncture for emesis (nausea and vomiting) during pregnancy, different cancer therapies, palliative care, after surgery, or to induce relaxing effects in general. Knowledge of side effects is central to shared decision-making.

AIM

To describe the type and frequency of side effects and the level of needle-induced pain during PC6 acupuncture.

METHODS

We included 1298 PC6 acupuncture treatments, delivered to 221 participants (77% women, mean age 52.5, range 18-91 years). The subjects had received genuine PC6 acupuncture, in one of two previous randomised controlled trials, aimed at inducing antiemetic (n=100, with 100 providing data on side effects and 94 on needle-induced pain, respectively) or relaxing (n=121, with 120 providing data) effects. Side effects during and after the acupuncture treatments were registered in structured treatment protocols and study diaries.

RESULTS

No serious complications occurred. Side effects during the acupuncture sessions included minor bleeding in 5.0%, tiredness in 4.9%, numbness in 4.5% and dizziness in 1.4% of the 1298 treatments. After treatment, the mean proportions of participants reporting side effects each week were: tiredness 25.8%; feeling cold 17.8%; dizziness 9.7%; sweating 9.3%; haematoma 8.8%; and soreness at the needling sites 4.3%. Participants perceived the needling to be not painful (47.4% of participants), or mildly (39.1%), moderately (11.6%) or very painful (1.4%).

CONCLUSIONS

Few side effects occurred and those that did were mild. Nearly 90% found PC6 acupuncture to be not painful or only mildly painful. Healthcare professionals may consider the observed levels of side effects when informing patients about side effects of PC6 acupuncture.

Thinking about one's own death after prostate-cancer diagnosis

BACKGROUND

Prostate-cancer diagnosis increases the risk for psychiatric morbidity and suicide. Thoughts about one's own death could indicate need for psychiatric care among men with localized prostate cancer. We studied the prevalence and predictors of thoughts about own death among men with prostate cancer.

METHODS

Of the 3930 men in the prospective, multi-centre LAPPRO-trial, having radical prostatectomy, 3154 (80%) answered two study-specific questionnaires, before and three months after surgery. Multivariable prognostic models were built with stepwise regression and Bayesian Model Averaging.

RESULTS

After surgery 46% had thoughts about their own death. Extra-prostatic tumor-growth [Adjusted Odds-Ratio 2.06, 95% Confidence Interval 1.66-2.56], university education [OR 1.66, CI 1.35-2.05], uncertainty [OR 2.20, CI 1.73-2.82], low control [OR 2.21, CI 1.68-2.91], loneliness [OR 1.75, CI 1.30-2.35], being a burden [OR 1.59, CI 1.23-2.07], and crying [OR 1.55, CI 1.23-1.96] before surgery predicted thoughts about one's own death after surgery.

CONCLUSIONS

We identified predictors for thoughts about one's own death after prostate cancer diagnosis and surgery. These factors may facilitate the identification of psychiatric morbidity and those who might benefit from psychosocial support already during primary treatment.

Acupuncture for neuropathic pain in adults

BACKGROUND

Neuropathic pain may be caused by nerve damage, and is often followed by changes to the central nervous system. Uncertainty remains regarding the effectiveness and safety of acupuncture treatments for neuropathic pain, despite a number of clinical trials being undertaken.

OBJECTIVES

To assess the analgesic efficacy and adverse events of acupuncture treatments for chronic neuropathic pain in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four Chinese databases, ClinicalTrials.gov and World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 14 February 2017. We also cross checked the reference lists of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) with treatment duration of eight weeks or longer comparing acupuncture (either given alone or in combination with other therapies) with sham acupuncture, other active therapies, or treatment as usual, for neuropathic pain in adults. We searched for studies of acupuncture based on needle insertion and stimulation of somatic tissues for therapeutic purposes, and we excluded other methods of stimulating acupuncture points without needle insertion. We searched for studies of manual acupuncture, electroacupuncture or other acupuncture techniques used in clinical practice (such as warm needling, fire needling, etc).

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcomes were pain intensity and pain relief. The secondary outcomes were any pain-related outcome indicating some improvement, withdrawals, participants experiencing any adverse event, serious adverse events and quality of life. For dichotomous outcomes, we calculated risk ratio (RR) with 95% confidence intervals (CI), and for continuous outcomes we calculated the mean difference (MD) with 95% CI. We also calculated number needed to treat for an additional beneficial outcome (NNTB) where possible. We combined all data using a random-effects model and assessed the quality of evidence using GRADE to generate 'Summary of findings' tables.

MAIN RESULTS

We included six studies involving 462 participants with chronic peripheral neuropathic pain (442 completers (251 male), mean ages 52 to 63 years). The included studies recruited 403 participants from China and 59 from the UK. Most studies included a small sample size (fewer than 50 participants per treatment arm) and all studies were at high risk of bias for blinding of participants and personnel. Most studies had unclear risk of bias for sequence generation (four out of six studies), allocation concealment (five out of six) and selective reporting (all included studies). All studies investigated manual acupuncture, and we did not identify any study comparing acupuncture with treatment as usual, nor any study investigating other acupuncture techniques (such as electroacupuncture, warm needling, fire needling).One study compared acupuncture with sham acupuncture. We are uncertain if there is any difference between the two interventions on reducing pain intensity (n = 45; MD -0.4, 95% CI -1.83 to 1.03, very low-quality evidence), and neither group achieved 'no worse than mild pain' (visual analogue scale (VAS, 0-10) average score was 5.8 and 6.2 respectively in the acupuncture and sham acupuncture groups, where 0 = no pain). There was limited data on quality of life, which showed no clear difference between groups. Evidence was not available on pain relief, adverse events or other pre-defined secondary outcomes for this comparison.Three studies compared acupuncture alone versus other therapies (mecobalamin combined with nimodipine, and inositol). Acupuncture may reduce the risk of 'no clinical response' to pain than other therapies (n = 209; RR 0.25, 95% CI 0.12 to 0.51), however, evidence was not available for pain intensity, pain relief, adverse events or any of the other secondary outcomes.Two studies compared acupuncture combined with other active therapies (mecobalamin, and Xiaoke bitong capsule) versus other active therapies used alone. We found that the acupuncture combination group had a lower VAS score for pain intensity (n = 104; MD -1.02, 95% CI -1.09 to -0.95) and improved quality of life (n = 104; MD -2.19, 95% CI -2.39 to -1.99), than those receiving other therapy alone. However, the average VAS score of the acupuncture and control groups was 3.23 and 4.25 respectively, indicating neither group achieved 'no worse than mild pain'. Furthermore, this evidence was from a single study with high risk of bias and a very small sample size. There was no evidence on pain relief and we identified no clear differences between groups on other parameters, including 'no clinical response' to pain and withdrawals. There was no evidence on adverse events.The overall quality of evidence is very low due to study limitations (high risk of performance, detection, and attrition bias, and high risk of bias confounded by small study size) or imprecision. We have limited confidence in the effect estimate and the true effect is likely to be substantially different from the estimated effect.

AUTHORS' CONCLUSIONS

Due to the limited data available, there is insufficient evidence to support or refute the use of acupuncture for neuropathic pain in general, or for any specific neuropathic pain condition when compared with sham acupuncture or other active therapies. Five studies are still ongoing and seven studies are awaiting classification due to the unclear treatment duration, and the results of these studies may influence the current findings.

Antiemetics: American Society of Clinical Oncology Clinical Practice Guideline Update

Purpose

To update the ASCO guideline for antiemetics in oncology.

Methods

ASCO convened an Expert Panel and conducted a systematic review of the medical literature for the period of November 2009 to June 2016.

Results

Forty-one publications were included in this systematic review. A phase III randomized controlled trial demonstrated that adding olanzapine to antiemetic prophylaxis reduces the likelihood of nausea among adult patients who are treated with high emetic risk antineoplastic agents. Randomized controlled trials also support an expanded role for neurokinin 1 receptor antagonists in patients who are treated with chemotherapy.

Recommendation

Key updates include the addition of olanzapine to antiemetic regimens for adults who receive high-emetic-risk antineoplastic agents or who experience breakthrough nausea and vomiting; a recommendation to administer dexamethasone on day 1 only for adults who receive anthracycline and cyclophosphamide chemotherapy; and the addition of a neurokinin 1 receptor antagonist for adults who receive carboplatin area under the curve ≥ 4 mg/mL per minute or high-dose chemotherapy, and for pediatric patients who receive high-emetic-risk antineoplastic agents. For radiation-induced nausea and vomiting, adjustments were made to anatomic regions, risk levels, and antiemetic administration schedules. Rescue therapy alone is now recommended for low-emetic-risk radiation therapy. The Expert Panel reiterated the importance of using the most effective antiemetic regimens that are appropriate for antineoplastic agents or radiotherapy being administered. Such regimens should be used with initial treatment, rather than first assessing the patient’s emetic response with less-effective treatment.

Randomized study exploring the combination of radiotherapy with two types of acupuncture treatment (ROSETTA): study protocol for a randomized controlled trial

Background

Adverse effects such as fatigue, pain, erythema, nausea and vomiting are commonly known in patients undergoing irradiation (RT) alone or in combination with chemotherapy (RCHT). Patients suffering from these symptoms are limited in their daily life and their quality of life (QOL) is often reduced. As addressed in several trials, acupuncture can cause amelioration of these specific disorders. Especially for pain symptoms, several groups have shown efficacy of acupuncture. To what extent the difference between traditional acupuncture (verum acupuncture) and false acupuncture (sham acupuncture) is in reducing side effects and improvement of QOL is not clear.

Methods/design

ROSETTA is a prospective randomized phase II trial (version 1.0) to examine the efficacy of traditional acupuncture in patients with RT-related side effects. In the experimental (verum) arm (n = 37) an experienced acupuncture-trained person will treat dedicated acupuncture points. In the control (sham) arm (n = 37) sham acupuncture will be performed to provide a blinded comparison of results.

Discussion

This is the first randomized prospective trial to evaluate the effect of traditional acupuncture on RT-related side effects such as fatigue and QOL.

A systematic review of methodologies, endpoints, and outcome measures in randomized trials of radiation therapy-induced nausea and vomiting

PURPOSE

Clinical trials in radiation therapy-induced nausea and vomiting (RINV) appear to have varied methodologies, endpoints, and outcome measures. This complicates trial comparisons, weakens practice guideline recommendations, and contributes to variability in supportive care patterns of practice. We systematically reviewed RINV trials to describe and compare their pertinent design features.

MATERIALS AND METHODS

Ovid versions of the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, EMBASE, and MEDLINE to January/February 2017 were searched for adult phase III trials of RINV management strategies. Key abstracted data included trial interventions and eligibility criteria, standard radiation therapy (RT) metrics, symptom assessment procedures, symptom definitions and grading systems, pre-specified and reported endpoints, and other outcome measures.

RESULTS

From 1166 references identified in the initial database search, we selected 34 trials for analysis that collectively randomized 4529 patients (median 61, range 11-1492). Twenty-eight trials (82%) were published prior to the year 2000. Twenty-seven trials (79%) involved multiple fraction RT and 7 (21%) single fraction RT. Twenty-four trials (71%) evaluated prophylactic interventions, 9 (26%) rescue interventions, and 1 trial did not specify. Thirty-three trials (97%) evaluated pharmacologic interventions. Twenty trials (59%) had patient report symptoms, 5 (15%) healthcare professionals or researchers, and 10 (29%) did not specify. Nausea was not defined in any trial but was reported as a stand-alone symptom in 26 trials (76%) and was graded in 20 (59%), with categorical qualitative scales being the most common method. Vomiting was defined in 3 trials (9%), was reported as a stand-alone symptom in 17 (47%), and was graded in 7 (21%), with continuous numerical scales being the most common method. Retching was defined in 3 trials, was not reported as a stand-alone symptom in any trial, and was graded in 1 (3%). Twenty-one trials (62%) created compound symptom measures that combined individual symptoms. Fifteen trials (44%) reported "emetic episode/event" measures but only 9 defined them. Seventeen trials (50%) reported complicated endpoints (e.g., "response," "control," "success") that combined multiple symptom or compound symptom measures, but 7 did not define them comprehensively. Ten trials (29%) defined a primary endpoint a priori.

CONCLUSIONS

Methodologies, endpoints, and outcome measures varied considerably among 34 randomized trials in RINV.

Reduced Need for Rescue Antiemetics and Improved Capacity to Eat in Patients Receiving Acupuncture Compared to Patients Receiving Sham Acupuncture or Standard Care during Radiotherapy

Objective. To evaluate if consumption of emesis-related care and eating capacity differed between patients receiving verum acupuncture, sham acupuncture, or standard care only during radiotherapy. Methods. Patients were randomized to verum (n = 100) or sham (n = 100) acupuncture (telescopic blunt sham needle) (median 12 sessions) and registered daily their consumption of antiemetics and eating capacity. A standard care group (n = 62) received standard care only and delivered these data once. Results. More patients in the verum (n = 73 of 89 patients still undergoing radiotherapy; 82%, Relative Risk (RR) 1.23, 95% Confidence Interval (CI) 1.01–1.50) and the sham acupuncture group (n = 79 of 95; 83%, RR 1.24, CI 1.03–1.52) did not need any antiemetic medications, as compared to the standard care group (n = 42 out of 63; 67%) after receiving 27 Gray dose of radiotherapy. More patients in the verum (n = 50 of 89; 56%, RR 1.78, CI 1.31–2.42) and the sham acupuncture group (n = 58 of 94 answering patients; 62%, RR 1.83, CI 1.20–2.80) were capable of eating as usual, compared to the standard care group (n = 20 of 63; 39%). Conclusion. Patients receiving acupuncture had lower consumption of antiemetics and better eating capacity than patients receiving standard antiemetic care, plausible by nonspecific effects of the extra care during acupuncture.

Effect of transcutaneous electrical acupoint stimulation combined with palonosetron on chemotherapy-induced nausea and vomiting: a single-blind, randomized, controlled trial

BACKGROUND

Chemotherapy-induced nausea and vomiting adversely affects the quality of life of patients who receive chemotherapy via intravenous infusion or transcatheter arterial chemoembolization (TACE). This study aimed to investigate the clinical effects of transcutaneous electrical acupoint stimulation (TEAS) on nausea and vomiting after TACE.

METHODS

A total of 142 patients who received TACE with cisplatin for primary or metastatic liver cancer were assigned to the active-acupuncture (n = 72) or placebo-acupuncture (n = 70) groups using a covariate-adaptive randomization at a ratio of 1:1. The acupoints Hegu (LI4), Neiguan (P6), and Zusanli (ST36) were stimulated twice daily for 6 days. The effects of TEAS on nausea and vomiting were assessed by using occurrence rate and severity of these symptoms. Anorexia scale and M. D. Anderson Symptom Inventory (MDASI) scores were secondary endpoints and were used to assess the effect of TEAS on patient appetite and quality of life. The safety of the treatments was also monitored.

RESULTS

Between the two groups, the differences in occurrence rates and severities of nausea and vomiting after TACE were not significant (all P > 0.05). From the second day after TACE, anorexia scores were significantly lower in the active-acupuncture group than in the placebo-acupuncture group and continued to decrease over time with treatment (all P values less than 0.01). On days 0, 1, and 2, the mean MDASI scores for the active-acupuncture group were slightly lower than those for the placebo-acupuncture group, but the differences were not statistically significant (all P > 0.05). No significant differences were found between the two groups in the occurrence rate of any adverse event (P > 0.05).

CONCLUSION

TEAS appears to be a safe and effective therapy to relieve patients' gastrointestinal discomfort after chemotherapy. Trial registration NCT01895010. Registered 21 June 2013.

Use of Complementary and Alternative Medicine (CAM) as Part of the Oncological Treatment: Survey about Patients' Attitude towards CAM in a University-Based Oncology Center in Germany

INTRODUCTION

To understand if and which patients would be open-minded to Complementary and Alternative Medicine (CAM) use parallel to their oncological treatment. Moreover, we sought to determine which methods are most accepted and which are the primary motivators to use CAM.

METHODS

We developed and anonymously conducted a questionnaire for patients in the oncology center (TU Munich). Questions focus on different CAM methods, previous experiences, and willingness to apply or use CAM when offered in a university-based setting.

RESULTS

A total of 171 of 376 patients (37.4% women, 62.0% men, 0.6% unknown) participated. This corresponds to a return rate of 45%. Median age was 64 years (17-87 years). Of all participants, 15.2% used CAM during their oncological therapy; 32.7% have used it in the past. The majority (81.9%) was not using CAM during therapy; 55.5% have not used CAM in the past respectively. The analysis revealed a significant correlation between education and CAM use during therapy (r = 0.18; p = 0.02), and CAM use in the past (r = 0.17; p = 0.04). Of all patients using CAM during therapy, favored methods were food supplements (42.3%), vitamins/minerals (42.3%), massage (34.6%). Motivations are especially the reduction of side effect and stress, the positive effect of certain CAM-treatments on the immune system and tumor therapy. Results showed no difference between women and men. Most patients not having had any experience with CAM complain about the deficiency of information by their treating oncologist (31.4%) as well as missing treatment possibilities (54.3%).

CONCLUSION

Since many patients believe in study results demonstrating the efficacy of CAM, it stresses our task to develop innovative study protocols to investigate the outcomes of certain CAM on symptom reduction or other endpoints. Thus, prospective trials and innovative evidence-based treatment concepts to include CAM into high-end oncology is what patients demand and what a modern oncology center should offer.

Use of acupuncture to alleviate side effects in radiation oncology: Current evidence and future directions

Several reports have shown that acupuncture is an effective method of complementary medicine; however, only a few of these reports have focused on oncological patients treated with radiation therapy. Most of these studies discuss a benefit of acupuncture for side-effect reduction; however, not all could demonstrate significant improvements. Thus, innovative trial designs are necessary to confirm that acupuncture can alleviate side effects related to radiation therapy. In the present manuscript, we perform a broad review and discuss pitfalls and limitations of acupuncture in parallel with standard radiation therapy, which lead the way to novel treatment concepts.

Adjunctive acupuncture for pain and symptom management in the inpatient setting: protocol for a pilot hybrid effectiveness-implementation study

BACKGROUND

Effective pain management among hospitalized patients is an important aspect of providing quality care and achieving optimal clinical outcomes and patient satisfaction. Common pharmacologic approaches for pain, though effective, have serious side effects and are not appropriate for all inpatients. Findings from randomized controlled trials (RCTs) support the efficacy of acupuncture for many symptoms relevant to inpatients including postoperative pain, cancer-related pain, nausea and vomiting, and withdrawal from narcotic use. However, the extent to which findings from RCTs translate to real-world implementation of acupuncture in typical hospital settings is unknown.

METHODS/DESIGN

In partnership with the launch of a clinical program offering acupuncture services to inpatients at the University of California San Francisco's Mount Zion Hospital, we are conducting a pilot study using a hybrid effectiveness-implementation design to: (1) assess the effectiveness of acupuncture to manage pain and other symptoms and improve patient satisfaction; and (2) evaluate the barriers and facilitators to implementing an on-going acupuncture service for inpatients. During a two-month pre-randomization phase, we evaluated and adapted clinical scheduling and treatment protocols with acupuncturists and hospital providers and pretested study procedures including enrollment, consent, and data collection. During a six-month randomization phase, we used a two-tiered consent process in which inpatients were first consented into a study of symptom management, randomized to be offered acupuncture, and consented for acupuncture if they accepted. We are also conducting in-depth interviews and focus groups to assess evidence, context, and facilitators of key provider and hospital administration stakeholders.

DISCUSSION

Effectiveness research in "real-world" practice settings is needed to inform clinical decision-making and guide implementation of evidence-based acupuncture practices. To successfully provide clinical acupuncture services and maintain a rigorous research design, practice-based trials of acupuncture require careful planning and attention to setting-specific, contextual factors.

TRIAL REGISTRATION

This trial has been registered in ClinicalTrials.gov. The identifier is NCT01988194, registered on November 5, 2013.

The Effects of Positive or Neutral Communication during Acupuncture for Relaxing Effects: A Sham-Controlled Randomized Trial

Introduction. The link between patient-clinician communication and its effect on clinical outcomes is an important clinical issue that is yet to be elucidated. Objective. Investigating if communication type (positive or neutral) about the expected treatment outcome affected (i) participants' expectations and (ii) short-term relaxation effects in response to genuine or sham acupuncture and investigating if expectations were related to outcome. Methods. Healthy volunteers (n = 243, mean age of 42) were randomized to one treatment with genuine or sham acupuncture. Within groups, participants were randomized to positive or neutral communication, regarding expected treatment effects. Visual Analogue Scales (0–100 millimeters) were used to measure treatment expectations and relaxation, directly before and after treatment. Results. Participants in the positive communication group reported higher treatment expectancy, compared to the neutral communication group (md 12 versus 6 mm, p = 0.002). There was no difference in relaxation effects between acupuncture groups or between communication groups. Participants with high baseline expectancy perceived greater improvement in relaxation, compared to participants with low baseline levels (md 27 versus 15 mm, p = 0.022). Conclusion. Our data highlights the importance of expectations for treatment outcome and demonstrates that expectations can be effectively manipulated using a standardized protocol that in future research may be implemented in clinical trials.

Nausea and vomiting induced by gastrointestinal radiation therapy: current status and future directions

PURPOSE OF REVIEW

Radiation therapy-induced nausea and vomiting (RINV) are common and troublesome symptoms among patients receiving radiation therapy for gastrointestinal cancers. Their impact on function, quality of life and, ultimately, cancer control warrant a review of their incidence, underlying mechanisms, treatments and research themes.

RECENT FINDINGS

Research in RINV is underrepresented relative to that in chemotherapy-induced nausea and vomiting. The incidence of RINV among patients receiving modern day radiation therapy is questioned and supportive care practice patterns vary among radiation oncologists. Antiemetic guideline recommendations for prophylactic and rescue therapy are based solely on the anatomic region being irradiated and not other patient-related, radiation therapy-related, or organ-specific dosimetric factors that likely modulate the risk of RINV. Dosimetric predictors are likely the most attainable biomarker moving forward, but only early steps have been taken. The small bowel and stomach will be the best first candidates for study among patients with gastrointestinal cancers. Studies of the mechanisms underlying RINV are conspicuously lacking. A new generation of observational studies and therapeutic clinical trials is needed, and more attention must be given to the relative impact of nausea and vomiting on the function and quality of life among specific homogeneous patient populations.

SUMMARY

Optimal supportive care strategies for RINV following radiation therapy for gastrointestinal cancers are lacking, and will not be known until future research answers the many open questions regarding the mechanisms underlying RINV, the true incidence and impact of these symptoms among patients and the best way to predict and mitigate them.

Electroacupuncture for postoperative pain and gastrointestinal motility after laparoscopic appendectomy (AcuLap): study protocol for a randomized controlled trial

Background

Acupuncture is a widely serviced complementary medicine. Although acupuncture is suggested for managing postoperative ileus and pain, supporting evidence is weak. The AcuLap trial is designed to provide high-level evidence regarding whether or not electroacupuncture is effective in promoting gastrointestinal motility and controlling pain after laparoscopic surgery.

Methods/design

This study is a prospective randomized controlled trial with a three-arm, parallel-group structure evaluating the efficacy of electroacupuncture for gastrointestinal motility and postoperative pain after laparoscopic appendectomy. Patients with appendicitis undergoing laparoscopic surgery are included and randomized into three groups: 1) electroacupuncture group, 2) sham acupuncture group, and 3) control group. Patients receive 1) acupuncture with electrostimulation or 2) fake electroacupuncture with sham device twice a day or 3) no acupuncture after laparoscopic appendectomy. The primary outcome is time to first passing flatus after operation. Secondary outcomes include postoperative pain, analgesics, nausea/vomiting, bowel motility, time to tolerable diet, complications, hospital stay, readmission rates, time to recovery, quality of life, medical costs, and protocol failure rate. Patients and hospital staff (physicians and nurses) are blinded to which group the patient is assigned, electroacupuncture or sham acupuncture. Data analysis personnel are blinded to group assignment among all three groups. Estimated sample size to detect a minimum difference of time to first flatus with 80 % power, 5 % significance, and 10 % drop rate is 29 × 3 groups = 87 patients. Analysis will be performed according to the intention-to-treat principle.

Discussion

The AcuLap trial will provide evidence on the merits and/or demerits of electroacupuncture for bowel motility recovery and pain relief after laparoscopic appendectomy.

Trial registration

The trial was registered in Clinical Research Information Service (CRiS), Republic of Korea (KCT0001486) on 14 May 2015.

A randomized, controlled, crossover study in patients with mild and moderate asthma undergoing treatment with traditional Chinese acupuncture

OBJECTIVES

This study sought to verify the effects of acupuncture as an adjuvant treatment for the control of asthma.

METHODS

This was a randomized, controlled, crossover trial conducted at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A total of 74 patients with mild/moderate, persistent asthma were randomized into two therapeutic groups: Group A - 31 patients underwent 10 real weekly acupuncture sessions, followed by a 3-week washout period and 10 sham weekly acupuncture sessions; and Group B - 43 patients underwent 10 sham weekly acupuncture sessions, followed by a 3-week washout period and 10 real weekly acupuncture sessions. Patients used short- and long-acting β-2 agonists and inhaled corticosteroids when necessary. Prior to treatment and after each period of 10 treatment sessions, the patients were evaluated for spirometry, induced sputum cell count, exhaled nitric oxide (NO) and with the Short Form 36 (SF-36) and Questionnaire on Quality of Life-Asthma (QQLA) questionnaires. Daily peak flow and symptom diaries were registered. The level of significance adopted was 5% (α=0.05).

RESULTS

In Group B, after real acupuncture, there was a decrease in eosinophils (p=0.035) and neutrophils (p=0.047), an increase in macrophages (p=0.001) and an improvement in peak flow (p=0.01). After sham acupuncture treatment, patients experienced less coughing (p=0.037), wheezing (p=0.013) and dyspnea (p=0.014); similarly, after real acupuncture, patients reported less coughing (p=0.040), wheezing (p=0.012), dyspnea (p<0.001) and nocturnal awakening episodes (p=0.009). In Group A, there was less use of rescue medication (p=0.043). After the sham procedure, patients in Group A experienced less coughing (p=0.007), wheezing (p=0.037), dyspnea (p<0.001) and use of rescue medication (p<0.001) and after real acupuncture, these patients showed improvements in functional capacity (p=0.004), physical aspects (p=0.002), general health status (p<0.001) and vitality (p=0.019). Sham acupuncture also led to significant differences in symptoms, but these were not different from those seen with real acupuncture. Spirometry and exhaled NO levels did not show a difference between sham and real acupuncture treatment. In addition, no significant difference was demonstrated between treatments regarding the quality of life evaluation.

CONCLUSION

Real and sham acupuncture have different effects and outcomes on asthma control. The crossover approach was not effective in this study because both interventions led to improvement of asthma symptoms, quality of life and inflammatory cell counts. Thus, sham acupuncture cannot serve as a placebo in trials with acupuncture as the main intervention for asthma.

The effectiveness and safety of acupuncture for poor semen quality in infertile males: a systematic review and meta-analysis

The aim of this review is to evaluate the effectiveness and safety of acupuncture for poor semen quality in infertile men. We searched for relevant trials registered up to May 2013 in 14 databases. We selected randomized controlled trials (RCTs) that compared acupuncture, with or without additional treatment, against placebo, sham, no treatment, or the same additional treatment. Two reviewers independently performed the study selection, data extraction, risk of bias and reporting quality appraisal. Risk of bias and reporting quality were appraised by the Cochrane risk of bias tool, the consolidated standards of reporting trials and Standards for Reporting Interventions in Clinical Trials of Acupuncture. The outcomes were sperm motility, sperm concentration, pregnancy rate, and adverse events. Pregnancy was defined as a positive pregnancy test. Four RCTs met the eligibility criteria. Acupuncture increased the percentage of sperm with rapid progression (mean difference - 6.35, 95% confidence interval (CI): 4.38-8.32, P< 0.00001) and sperm concentration (mean difference - 6.42, 95% CI: 4.91-7.92, P< 0.00001), but these two outcomes were substantially heterogeneous among the studies (I² = 72% and 58%, respectively). No differences in pregnancy rate were found between acupuncture and control groups (odds ratio 1.60, 95% CI: 0.70-3.69, P= 0.27, I² = 0%). No participants experienced adverse events. The current evidence showing that acupuncture might improve poor semen quality is insufficient because of the small number of studies, inadequacy of procedures and/or insufficient information for semen analysis, high levels of heterogeneity, high risk of bias, and poor quality of reporting. Further large, well-designed RCTs are required.

Real world research: a complementary method to establish the effectiveness of acupuncture

Background

Acupuncture has been widely used in the management of a variety of diseases for thousands of years, and many relevant randomized controlled trials have been published. In recent years, many randomized controlled trials have provided controversial or less-than-convincing evidence that supports the efficacy of acupuncture. The clinical effectiveness of acupuncture in Western countries remains controversial.

Discussion

Acupuncture is a complex intervention involving needling components, specific non-needling components, and generic components. Common problems that have contributed to the equivocal findings in acupuncture randomized controlled trials were imperfections regarding acupuncture treatment and inappropriate placebo/sham controls. In addition, some inherent limitations were also present in the design and implementation of current acupuncture randomized controlled trials such as weak external validity. The current designs of randomized controlled trials of acupuncture need to be further developed. In contrast to examining efficacy and adverse reaction in a “sterilized” environment in a narrowly defined population, real world research assesses the effectiveness and safety of an intervention in a much wider population in real world practice. For this reason, real world research might be a feasible and meaningful method for acupuncture assessment.

Summary

Randomized controlled trials are important in verifying the efficacy of acupuncture treatment, but the authors believe that real world research, if designed and conducted appropriately, can complement randomized controlled trials to establish the effectiveness of acupuncture. Furthermore, the integrative model that can incorporate randomized controlled trial and real world research which can complement each other and potentially provide more objective and persuasive evidence.

Effect of acupuncture for radioactive-iodine-induced anorexia in thyroid cancer patients: a randomized, double-blinded, sham-controlled pilot study

OBJECTIVE

The aim of this study is to evaluate the efficacy and safety of acupuncture for radioactive iodine (RAI)-induced anorexia in thyroid cancer patients.

METHODS

Fourteen thyroid cancer patients with RAI-induced anorexia were randomized to a true acupuncture or sham acupuncture group. Both groups were given 6 true or sham acupuncture treatments in 2 weeks. Outcome measures included the change of the Functional Assessment of Anorexia and Cachexia Treatment (FAACT; Anorexia/Cachexia Subscale [ACS], Functional Assessment of Cancer Therapy-General [FACT-G]), Visual Analogue Scale (VAS), weight, body mass index (BMI), ACTH, and cortisol levels.

RESULTS

The mean FAACT ACS scores of the true and sham acupuncture groups increased from baseline to exit in intention-to-treat (ITT) and per protocol (PP) analyses; the true acupuncture group showed higher increase but with no statistical significance. Between groups, from baseline to the last treatment, statistically significant differences were found in ITT analysis of the Table of Index (TOI) score (P = .034) and in PP analysis of the TOI (P = .016), FACT-G (P = .045), FAACT (P = .037) scores. There was no significant difference in VAS, weight, BMI, ACTH, and cortisol level changes between groups.

CONCLUSION

Although the current study is based on a small sample of participants, our findings support the safety and potential use of acupuncture for RAI-induced anorexia and quality of life in thyroid cancer patients.

Patients' Perspectives on Integrating Acupuncture into the Radiation Oncology Setting

INTRODUCTION

Acupuncture has potential as a supportive care service for cancer symptom management. However, little is known about patients' willingness to use acupuncture in the context of conventional cancer care.

METHODOLOGY

We conducted a cross-sectional survey study among patients with cancer during their last week of fractionated/external beam radiotherapy (RT). The main outcome variable was self-reported likelihood of using acupuncture during RT. Knowledge about acupuncture and pain severity was measured along with socio-demographic and clinical variables. Multivariate logistic regression was performed to identify factors associated with willingness to use acupuncture.

RESULTS

Among the 305 participants, 79 (26.4%) were likely to use acupuncture during RT if such services were offered at a reasonable price, 143 (46.9%) had no knowledge of acupuncture, and 206 (67.6%) reported having pain. In multivariate analyses, non-Whites (adjusted odds ratio [AOR] 1.94, 95% Confidence Interval [CI] 1.06-3.56), and those with pain (AOR 2.52, CI 1.25-5.10) were more interested in using acupuncture. In addition, patients with preexisting knowledge about acupuncture were also more likely to use acupuncture than those without this knowledge (AOR 2.23, CI 1.28-3.88).

CONCLUSIONS

Patients of non-White race, those with pain or those with prior knowledge about acupuncture were more willing to utilize acupuncture during RT. Since half of the patients had no knowledge about acupuncture, interventions to improve patients' knowledge are needed to facilitate the successful integration of acupuncture into cancer care.

Integrating acupuncture into cancer care

Oncology acupuncture has become a new and promising field of research because more and more cancer patients have sought non-pharmacological alternatives for symptom management. While different mechanisms have been proposed to explain its efficacy, including theories of the neural system, endocrine cytokine or immunological regulation, its eventual role has become that of alleviating the side effects induced by chemotherapy or radiotherapy. In this paper, we have reviewed the related articles focusing on acupuncture mechanisms and applications in cancer care to provide a quick sketch of acupuncture in cancer care. A detailed search was performed to identify the randomized controlled trials (RCTs) and systematic reviews on acupuncture in oncology, using PUBMED and Cochrane. The search terms included: Acupuncture, acupressure, and cancer. Additional terms were used to target specific symptoms (i.e., breast cancer, hot flash, xerostomia, nausea, vomiting, cancer pain, insomnia, fatigue). Two authors independently extracted data for analysis and review. Ultimately, 25 articles underwent full-text review. Recent trials made efforts in studying (a) hot flashes in breast cancer, (b) xerostomia induced by radiotherapy in head and neck cancer, (c) nausea and vomiting post-chemotherapy, (d) cancer pain, and (e) fatigue and insomnia in cancer patients. Controversial results for acupuncture application in cancer care appeared in different categories, but a trend emerged that acupuncture can palliate cancer-related symptoms. The research to date certainly offers us a valid complementary therapy in treating cancer-related symptoms. Meanwhile, practical strategies with safe measures for enhancing the efficacy are needed in further interventions, as well as continuing research with a validated methodology.
