Effect of Relaxation With Guided Imagery on The Physical and Psychological Symptoms of Breast Cancer Patients Undergoing Chemotherapy

Integrative Management of Cancer Pain: A Scoping Review of the Literature

BACKGROUND

Cancer-related pain is common and debilitating. Patients frequently use integrative medicine therapies to manage this, though safety and efficacy evidence is incomplete. This scoping review aims to characterize the state of integrative cancer pain therapy (ICPT) and identify priorities for future research.

METHODS

Following PRISMA guidelines, we searched PubMed, Embase, Web of Science, PsycINFO, CINAHL, and Cochrane for ICPT studies published between January 1, 1975 and May 26, 2022. Study findings were extracted and analyzed using descriptive statistics and thematic analysis. Interventions were categorized as follows: Whole Systems of Medicine (WSM); Mind-body Medicine (MBM); Botanicals and Supplements (BAS); and Manual Therapies (MT). Quality appraisal was performed using the Downs and Black checklist. Efficacy was "positive" if there were statistically significant differences between study arms (p < 0.05) favoring ICPT.

RESULTS

Among 1246 studies reviewed, 151 met inclusion criteria; 63.5% were excellent or good quality, and 68.9% were RCTs; 122 studies (80.7%) were published since 2010. Studies occurred in 24 countries, in variable settings, among participants with a wide range of cancers, disease status, and age ranges. Studies investigating WSM and MBM interventions were most frequent (35.7% for each), MT (20.59%), and BAS (7.9%). Overall, of the included studies, 127 (84.1%) found that the ICPT intervention reduced pain.

CONCLUSIONS

Studies on ICPT are increasingly common, and the majority of ICPT interventions demonstrated a positive impact on cancer pain. Future rigorous research should compare efficacy across integrative and biomedical interventions and explore how to incorporate evidence-based ICPT into standard cancer treatment.

Non-pharmacological Therapies for Depression in Women With Breast Cancer at Different Treatment Phases: A Systematic Review and Network Meta-Analysis

CONTEXT

Various non-pharmacological therapies (NPTs) have been found to be helpful for depression in women with breast cancer (BC). However, the relative efficacy of different NPTs in women with BC during different treatment phases is unclear.

OBJECTIVES

To conduct a systematic review and network meta-analysis (NMA) to compare the relative efficacy of various NPTs for improving depression in women with BC during the inter-/post-treatment periods.

METHODS

We searched eight databases (Embase, PubMed, PsycINFO, The Cochrane Library, Chinese Biomedical Database, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and WanFang Database) to identify relevant randomized controlled trials published in English and Chinese from their inception to 31 January 2024. We assessed the methodological quality of the included studies using the Cochrane Collaboration Risk of Bias Tool. NMA was conducted using a frequentist approach. The surface under the cumulative ranking (SUCRA) probabilities were used to rank the NPTs.

RESULTS

A total of 41 articles involving 5408 participants studied 18 NPTs. Based on NMA, in the intertreatment phase, mindfulness-based cognitive therapy (MBCT), psychological education, virtual reality (VR) and yoga significantly improved depression in women with BC. MBCT, psychological education, and VR were the three most effective NPTs in this period. In the post-treatment phase, mindfulness-based stress reduction significantly improved depression in women with BC, which was the most effective NPTs in this period. Based on the GRADE framework, most results were rated as "high" to "very low" for the confidence of evidence.

CONCLUSIONS

Our study confirmed the efficacy of several NPTs for depression in women with BC during inter-/post-treatment phases. These results should inform future clinical decisions and guidelines for depression in women with BC.

Guided Imagery for Symptom Management of Patients with Life-Limiting Illnesses: A Systematic Review of Randomized Controlled Trials

Background: Patients with life-limiting illnesses receiving palliative care have a high symptom burden that can be challenging to manage. Guided imagery (GI), a complementary and integrative therapy in which patients are induced to picture mental images with sensory components, has proven in quasi-experimental studies to be effective as a complementary therapy for symptom management. Objective: To systematically review randomized controlled trials that report evidence of guided imagery for symptom management in patients with life-limiting illnesses. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed for this review and the search strategy was applied in Medline, CINHAL, and Web of Science. The quality of articles was evaluated using the Cochrane Collaboration's Risk-of-Bias Tool 2 (RoB 2). The results are presented using the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews. Results: A total of 8822 studies were initially identified through the search strategy, but after applying exclusion criteria, 14 randomized controlled trials were included in this review. The quality assessment revealed that four studies had a high risk of bias, nine had some concerns, and one had a low risk of bias. Out of the 14 studies, 6 evaluated oncological diagnosis, while the remaining 8 focused on nononcological diagnoses across 6 different diseases. GI was found to be effective in managing symptoms in 10 out of the 14 studies. Regardless of the disease stage, patients who received guided imagery experienced relief from anxiety, depression, pain, sleep disturbances, and fatigue. Conclusion: GI therapy has shown promising results regarding symptom management in palliative care patients with life-limiting illnesses at different stages.

The Effect of Jacobson Relaxation Technique on Sleep Quality of Patients With Cancer Under Chemotherapy: A Randomized Clinical Trial

Introduction

Sleep is one of the most crucial basic human needs in Maslow's hierarchy, while sleep disorders are the most commonly occurring complications of chemotherapy.

Objective

This study was conducted to determine the effect of progressive muscle relaxation techniques on the sleep quality of patients with cancer undergoing chemotherapy.

Methods

This study was a randomized clinical trial performed on patients with cancer undergoing chemotherapy. Ninety cancer patients were selected by the convenience sampling method and randomly assigned into two groups; the progressive muscle relaxation group and the control group. Before the intervention, the Pittsburgh Sleep Quality Questionnaire (PSQQ) was completed for patients in both groups. In the intervention group, progressive muscle relaxation was performed for 4 weeks (twice daily and 20 min each time). In the control group, patients only received routine care. After the intervention, the PSQQ was completed again for patients in both groups. The data were analyzed using SPSS version 23.

Results

The mean and standard deviation of age were 45.95 ± 10.26 years. The samples of the intervention and control groups were homogeneous in terms of demographic characteristics. The results showed a significant improvement in the Pittsburgh Sleep Quality Index in the intervention group before and after the intervention (P < .001, Z = 5.09). However, this rate was not different in the control group. The sleep level of the intervention and control groups was not different at the beginning of the study. However, at the end of the study, the sleep score in the intervention group had decreased significantly (P < .001, Z = 3.52).

Conclusion

The results of the present study showed that progressive muscle relaxation improves the sleep quality of patients with cancer undergoing chemotherapy. Therefore, relaxation can be considered a useful and effective intervention for improving sleep quality of patients with cancer.

Psychosocial Interventions for Pain Management in Breast Cancer Survivors: A RE-AIM Evaluation

Psychosocial interventions for breast-cancer-related pain are effective, yet over 45% of survivors continue to struggle with this often-chronic side effect. This study evaluated multilevel indicators that can influence successful translation of interventions into clinical practice. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was applied to evaluate reporting of individual and setting/staff-level intervention indicators. A systematic search and multi-step screening process identified 31 randomized controlled trials for psychosocial interventions for breast cancer-related pain. Average reporting of indicators for individual-level dimensions (Reach and Effectiveness) were 65.2% and 62.3%, respectively. Comparatively, indicators for setting/staff-level dimensions were reported at a lower average frequency (Implementation, 46.8%; Adoption, 15.2%; Maintenance, 7.7%). Low reporting of setting/staff-level dimensions suggests gaps in the sustained implementation of psychosocial interventions. Implementation science methods and frameworks could improve trial design and accelerate the translation of psychosocial interventions for breast cancer-related pain into clinical practice.

Psychological interventions for women with non-metastatic breast cancer

BACKGROUND

Breast cancer is the most common cancer affecting women worldwide. It is a distressing diagnosis and, as a result, considerable research has examined the psychological sequelae of being diagnosed and treated for breast cancer. Breast cancer is associated with increased rates of depression and anxiety and reduced quality of life. As a consequence, multiple studies have explored the impact of psychological interventions on the psychological distress experienced after a diagnosis of breast cancer. This review is an update of a Cochrane Review first published in 2015.

OBJECTIVES

To assess the effect of psychological interventions on psychological morbidities and quality of life among women with non-metastatic breast cancer.  SEARCH METHODS: We searched the Cochrane Breast Cancer Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov up to 16 March 2021. We also scanned the reference lists of relevant articles.

SELECTION CRITERIA

Randomised controlled trials that assessed the effectiveness of psychological interventions for women with non-metastatic breast cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently appraised, extracted data from eligible trials, and assessed risk of bias and certainty of the evidence using the GRADE approach. Any disagreement was resolved by discussion. Extracted data included information about participants, methods, the intervention and outcomes.

MAIN RESULTS

We included 60 randomised controlled trials comprising 7998 participants. The most frequent reasons for exclusion were non-randomised trials and the inclusion of women with metastatic disease. The updated review included 7998 randomised women; the original review included 3940 women. A wide range of interventions was evaluated. Most interventions were cognitive- or mindfulness-based, supportive-expressive, and educational. The interventions were mainly delivered face-to-face (56 studies) and in groups (50 studies) rather than individually (10 studies). Most intervention sessions were delivered on a weekly basis with an average duration of 14 hours. Follow-up time ranged from two weeks to 24 months.  Pooled standardised mean differences (SMD) from baseline indicated that the intervention may reduce depression (SMD -0.27, 95% confidence interval (CI) -0.52 to -0.02; P = 0.04; 27 studies, 3321 participants, I2 = 91%, low-certainty evidence); anxiety (SMD -0.43, 95% CI -0.68 to -0.17; P = 0.0009; 22 studies, 2702 participants, I2 = 89%, low-certainty evidence); mood disturbance in the intervention group (SMD -0.18, 95% CI -0.31 to -0.04; P = 0.009; 13 studies, 2276 participants, I2 = 56%, low-certainty evidence); and stress (SMD -0.34, 95% (CI) -0.55 to -0.12; P = 0.002; 8 studies, 564 participants, I2 = 31%, low-certainty evidence). The intervention is likely to improve quality of life in the intervention group (SMD 0.78, 95% (CI) 0.32 to 1.24; P = 0.0008; 20 studies, 1747 participants, I2 = 95%, low-certainty evidence). Adverse events were not reported in any of the included studies.

AUTHORS' CONCLUSIONS

Based on the available evidence, psychological intervention may have produced favourable effects on psychological outcomes, in particular depression, anxiety, mood disturbance and stress. There was also an improvement in quality of life in the psychological intervention group compared to control group. Overall, there was substantial variation across the studies in the range of psychological interventions used, control conditions, measures of the same outcome and timing of follow-up.

Efficacy of New Mindfulness-Based Swinging Technique Intervention: A Pilot Randomised Controlled Trial Among Women With Breast Cancer

Objective

Combining 3rd-wave-therapies with Cognitive-Behavioural-Therapy (CBT) has increased in recent years. Usually these therapies require longer sessions which therefore increases the psychotherapy drop-out rate for cancer patients for multiple medical reasons. This inspired intervention of a shorter 20 min-long mindfulness-therapy (MBST) to be developed for Breast-Cancer-patients (BC).

Method

This pilot randomised controlled trial was to assess the immediate-outcome of the MBST-intervention for its efficacy for BC-patients by using the Pearson Chi-square test, Fisher-Freeman-Halton exact test, and McNemar test for categorical variables; Mann-Whitney U and Wilcoxon test for the continuous variables. The Emotion Thermometer, State Trait Anxiety Inventory, Hospital Anxiety and Depression Scale, Self-Efficacy for Managing Chronic Disease, and Beck's Hopelessness Scale were used for measuring the intervention outcomes. One hundred seventy-three BC patients were randomly assigned in two-groups (equal-mean-age, p = 0.417). Control-Group (CG, n = 82) received cognitive-disputation-technique a form-of-CBT, and Intervention-Group (IG, n = 74) received MBST. The directives are given to IG: psychoeducation about Mindfulness, and to imagine themselves swinging-in a peaceful environment. When the patients imagine their swing going up, they physically take a deep-breath, and when going down they physically release their breath, and this process is repeated.

Result

Outcomes post-treatment showed significant higher-improvement in IG in all the assessed-measurements, with large-effect-size: anxiety (p < 0,05, r = 0,67) and depression-levels (p < 0,05, r = 0,71); anxiety-trait (p < 0,05; r = 0,79) reduced, it increases self-efficacy for managing-disease (p < 0,05, r = 0,82) as-well-as hopefulness (p < 0,05, r = 0,61) and saturation-level measured by pulse-meter/oximeter (p < 0,05, r = 0,51).

Conclusion

MBST is an efficacious intervention to reduce psychotherapy session time for immediate relief from clinical anxiety and hopelessness as well as increase self-efficacy and improve tranquillity for BC-women. It may have a particular clinical significance for supporting patient's adherence to treatment. Although in this pilot sample MBST was found to be effective for short-term-outcome, its efficacy for longer-term-outcome should be examined in future trials. Additionally, breathing laps can be increased possibly for a greater result on rise of saturation levels of patients.

Psychological Interventions in Chemotherapy-Induced Nausea and Vomiting in Women with Breast Cancer: A Systematic Review

Background

Nausea and vomiting are considered the most common side effects of chemotherapy, and they can affect different dimensions of the lives of women with breast cancer. Thus, the management of these complications is of great significance. Various interventions are drawn upon to alleviate nausea and vomiting. This review aimed to investigate the effects of psychological interventions on chemotherapy-induced nausea and vomiting among women with breast cancer.

Methods

A systematic review of clinical or quasi-experimental clinical trials published from 2000 to 2020 on the effects of psychological interventions on nausea and vomiting induced by chemotherapy in women with breast cancer was conducted via a comprehensive search in web search engines including Google Scholar and PubMed and databases such as Web of Science, Scopus, ScienceDirect, Cochrane Library, Springer, Elsevier, Magiran, and Scientific Information Database (SID). Medical Subject Heading (MeSH) was employed with the following keywords: nausea, vomiting, breast cancer, chemotherapy, and psychological intervention. The quality of the included studies was assessed via the Jadad scale.

Results

Nine studies were included in this systematic review. Psychological interventions in chemotherapy-induced nausea and vomiting in women with breast cancer consisted of cognitive-behavioral therapy, progressive muscle relaxation training, yoga, and guided imagery. The results indicated that in all the studies, except one, the interventions improved conditions and reduced chemotherapy-induced nausea and vomiting.

Conclusion

The results of this study indicated that psychological interventions such as cognitive-behavioral therapy, progressive muscle relaxation training, guided imagery, and yoga alleviated nausea and vomiting induced by chemotherapy in women with breast cancer. Therefore, it is recommended that these interventions be applied by healthcare providers to ameliorate nausea and vomiting in these patients.The abstract was presented in the 15th International Congress on Obstetrics and Gynecology, Tehran, Iran, 8-11 October 2019, as a poster and published in the congress book.

The Effect of Hypnosis on the Intensity of Pain and Anxiety in Cancer Patients: A Systematic Review of Controlled Experimental Trials

BACKGROUND

Pain is a common symptom in cancer patients. Hypnosis is considered one of the most recognized non-pharmacological techniques in pain management. In oncology, this technique can be used as a complementary treatment to reduce the level of pain and anxiety. The objective of this study is to systematically review and evaluate controlled clinical trials (CCTs) examining the effect of hypnosis on the intensity of pain, and anxiety in cancer patients.

METHODS

A systematic review was conducted according to the recommendations of the "Preferred reporting items for systematic reviews and meta-analyses" (PRISMA). The Cochrane systematic review database, the abstract databases, Scopus, PubMed, Google Scholar, and Cochrane Library have been systematically reviewed from 2005 to 2018.

RESULTS

Eleven CCT with a total of 1182 participants met the inclusion criteria and were included in this review. The participants were mainly women (n = 968). Their average age alternates between 48 and 58 years. Perceived pain was measured primarily by visual analog scale (VAS)/numerical pain rating scale (NPRS), which showed that anxiety was measured by Hospital Anxiety and Depression scale (HADS). Hypnosis-related anxiety and pain decreased significantly with respect to usual treatment.

CONCLUSIONS

Evidence suggests promising results of hypnosis on the management of pain, and anxiety levels in the vast majority of cancer patients. Therefore, because of the exploratory design and high risk of bias, the effectiveness of hypnosis or hypnotherapy in reducing pain and anxiety levels remains unclear. There is a need for more rigorous randomized controlled trials (RCTs).

Are mind-body therapies effective for relieving cancer-related pain in adults? A systematic review and meta-analysis

OBJECTIVE

To assess whether mind-body therapies are effective for relieving cancer-related pain in adults, since at least one-third of adults with cancer are affected by moderate or severe pain.

METHODS

We searched for all randomized or quasi-randomized controlled trials that included adults (≥18 years) with cancer-related pain who were treated with mind-body therapies (mindfulness, hypnosis, yoga, guided imagery, and progressive muscle relaxation) in MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Science Citation Index, Web of Science, trials registers, and reference lists. The primary outcome was pain intensity. We calculated the standardized mean differences and 95% confidence intervals (CIs) and assessed the risk of bias.

RESULTS

We identified 40 primary studies involving a total of 3569 participants. The meta-analysis included 24 studies (2404 participants) and showed a significant effect of -0.39 (95% CI -0.62 to -0.16) with considerable heterogeneity (I²  = 86.3%, p < 0.001). After we excluded four "outlier" studies in sensitivity analyses, the effect size remained significant but weaker. There was a high risk of bias in all studies, for example, performance bias due to lack of participant blinding. Patients in multiple settings were included but many studies were of low quality.

CONCLUSIONS

Mind-body therapies may be effective in improving cancer pain, but the quality of the evidence is low. There is a need for further high-quality clinical trials.

Progressive Muscle Relaxation and Guided Imagery in Breast Cancer: A Systematic Review and Meta-analysis of Randomised Controlled Trials

Breast cancer affects the mental well-being of patients who may need psychological support. The combined practice of progressive muscle relaxation (PMR) and guided imagery (GI) is known to improve psychological health. Its effect has been studied in patients with breast cancer. We need to systematically review and analyse the available data to outline its role in various stages of disease management. We wanted to evaluate the effect of the combined practice of PMR and GI on stress, anxiety, depression and mood. We also wanted to study the impact on quality of life and chemotherapy-related adverse effects. A systematic search and evaluation of the literature was performed. Five randomised controlled trials were selected for data extraction and construction of forest plots. The intervention was effective for stress and anxiety. It positively improved the quality of life but saw no significant improvement in chemotherapy-related adverse effects.

The Feasibility and Efficacy of Self-help Relaxation Exercise in Symptom Distress in Patients With Adult Acute Leukemia: A Pilot Randomized Controlled Trial

AIMS

To examine the feasibility and efficacy of self-help relaxation exercises in alleviating symptom distress in adult patients with acute leukemia (AL).

METHODS

A pilot randomized controlled trial was used. Thirty adult patients with AL who were hospitalized in a teaching hospital were enrolled and randomly divided into a wait-list control group or an intervention group. The intervention group received self-help relaxation exercise twice per day for 4 weeks. The feasibility indicators, patients' symptom distress were assessed by a blinded data collector.

RESULTS

Twenty-nine patients completed the study. The recruitment rate, retention rate, and adherence rate was 65.2%, 93.3%, and 98.2%, respectively. The intervention group had a significantly decreased distress score for pain symptoms (F_{1, 27} = 6.594, P = .016, the partial η² = 0.20, 90% confidence interval = 0.02-0.39).

CONCLUSIONS

Self-help relaxation exercises were feasible for the AL patients and significantly reduced their pain symptoms. Minor revision of the protocol for future definitive trials is needed.

Effect of Progressive Muscle Relaxation Therapy on Fatigue and Psychological Distress of Cancer Patients during Radiotherapy: A Randomized Controlled Trial

Background:

Patients with cancer receiving radiotherapy experiences fatigue and psychological distress. Now a days there has been growing interest towards managing these symptoms with non-pharmacological treatments, But researches related to effect of progressive muscle relaxation therapy on fatigue and psychological distresses related to admitted patients are limited hence the aim of the study to evaluate the effect of progressive muscle relaxation therapy on fatigue and psychological distress in Cancer patients during Radiotherapy.

Aims and Objectives:

Aim of the study to evaluate the effect of progressive muscle relaxation therapy on fatigue and psychological distress in Cancer patients during Radiotherapy.

Materials and Methods:

The study design was single blinded randomized control trial. Total of 50 patients, for both intervention and control group 25 patients were included. The intervention group patients received P.M.R. therapy of 20 min. given for 3 times/week of total period of 3 weeks, whereas the control group received conventional treatment with no added intervention. Fatigue symptom inventory and hospital anxiety and depression scale used as an outcome measures.

Results:

Paired t-test used for FSI to compare among intervention and control group and results were showing statistical significant difference (P < 0.05), similarly pre and post improvement was observed in both the groups for HADS. Between group comparison showed no superior improvement one over the other.

Conclusion:

Based on the above findings, P.M.R. and conventional treatment were similarly efficacious in decreasing fatigue and psychological distress related to cancer patients who were hospitalized undergoing radiotherapy.

The Effect of Family-Centered Supportive Program on Chemotherapy-Induced Symptoms in Patients with Acute Lymphoblastic Leukemia (ALL)

Background: Acute lymphoblastic leukemia is a disease of the hematopoietic system and chemotherapy is recommended as the primary treatment. As many chemotherapeutic agents have severe adverse effects, patients require to be supported by their family to deal with chemotherapy-related symptoms. This study attempted to investigate the effect of family-centered supportive programs on chemotherapy symptom control in patients with acute lymphoblastic leukemia. Materials and Methods: Sixty-six patients with acute lymphoblastic leukemia undergoing chemotherapy along with their caregivers participated in this nonrandomized clinical trial. Patients in Shariati and Taleghani Hospital were assigned to intervention (n=33) and control group (n=33), respectively. A survey of family-centered supportive program was conducted via in-person and telephone up to 6 cycles of chemotherapy. The chemotherapy symptom assessment scale was administered to record the data during 6 cycles of chemotherapy treatment. The control group only received routine interventions. Data were analyzed using Chi-square and Mann-Whitney U tests. Results: The results of the study indicated that there was a statistically significant difference in terms of the frequency of 9 chemotherapy-induced symptoms including nausea, shortness of breath, problems related to skin and nails, a sore/sensitive mouth or throat, anorexia, weight gain or loss, headache and sore/scratchy/dry eyes between the control and intervention group. There was also a statistically significant difference in the severity and level of discomfort of 19 chemotherapy-induced symptoms between the control and intervention group. Conclusion: Family-centered supportive program can be considered as an approach to decrease the frequency, severity and discomfort level of chemotherapy-induced symptoms.

Effects of a Mindfulness Intervention on Hospitalized Patients With Hematologic Malignancies and Their Caregivers

OBJECTIVES

To examine the effects of a mind-body intervention on the psychological distress of hospitalized patients with hematologic malignancies and their caregivers.

SAMPLE & SETTING

29 patients with hematologic malignancies and 5 caregivers were recruited from the bone marrow transplantation unit at Barnes-Jewish Hospital in St. Louis, Missouri.

METHODS & VARIABLES

After completing the Rotterdam Symptom Checklist (RSCL) to rate their levels of psychological and physiologic distress and quality of life, participants were taught a mindfulness activity. Two weeks postintervention, participants completed the RSCL again, reported how often they practiced the activity, and answered qualitative questions regarding their experience.

RESULTS

Participants reported increased relaxation and improved sleep and showed interest in practicing mindfulness as a part of their treatment plan.

IMPLICATIONS FOR NURSING

Nurses can help to alleviate symptoms of distress in patients with hematologic malignancies by integrating education on how to perform short and simple mindfulness activities into the care plan.

Non-pharmacological therapies for depressive symptoms in breast cancer patients: Systematic review and meta-analysis of randomized clinical trials

OBJECTIVE

Depressive symptoms are common comorbidities among breast cancer (BC) patients. Non-pharmacological therapies (NPTs) such as exercise and psychotherapy may reduce depressive symptoms; however, the evidence is inconclusive. The objective of this study is to evaluate if NPTs reduce depressive symptoms among BC patients.

METHODS

A systematic review and meta-analysis of randomized clinical trials (RCTs) of NPTs for BC patients were performed. A literature search was conducted from eight databases in English, Portuguese and Spanish from 2006 to 2017. Inclusion criteria were: RCTs that evaluated depressive symptoms as a primary or secondary outcome that did not include pharmacological interventions and did include a non-intervened control group, with at least 30 participants in non-terminal BC stage with no current psychiatric illness. A meta-analysis for each NPT was performed with DerSimonian and Laird's method for the random effects model. Sensitivity analyses were conducted. Heterogeneity and publication bias were assessed.

RESULTS

A total of 41 eligible RCTs were identified. Overall, NPTs significantly reduced depressive symptoms (Summary standardized mean difference (SMD) = -0.516; 95%CI: -0.814, -0.218; I2 = 96.2). Of the types of NPTs, psychotherapy significantly reduced depressive symptoms (Summary SMD = -0.819; 95% CI: -1.608, -0.030; I2 = 91.53). A significant difference emerged for Mindfulness (Summary SMD = -0.241; 95% CI: -0.412, -0.070; I2 = 28.6%) and yoga (Summary SMD = -0.305; 95% CI: -0.602, -0.007; I2 = 41.0%) when the heterogeneity was reduced. No evidence of publication bias was observed.

CONCLUSIONS

Psychotherapy and mind-body therapies may reduce depressive symptoms in women with BC. Laughter and couples therapy warrant attention in future studies.

Association between chronological depressive changes and physical symptoms in postoperative pancreatic cancer patients

Background

Pancreatic cancer (PC) has poorer prognosis and higher surgical invasiveness than many other cancers, with associated psychiatric symptoms including depression and anxiety. Perioperative depression has not been investigated in PC patients regarding surgical stress and relevant interventions.

Methods

We evaluated chronological depressive changes and subjective physical symptoms in surgically treated PC patients preoperatively and at 3 and 6 months postoperatively.

Enrolled patients undergoing pancreatic tumor surgery completed questionnaires based on the Self-Rating Depression Scale (SDS) and Functional Assessment of Cancer Therapy for Patients with Hepatobiliary Cancer (FACT-Hep) preoperatively, and at 3 and 6 months postoperatively. Responses were analyzed with JMP® Pro using one-way and two-way ANOVA, Spearman’s rank correlation coefficient, and multiple regression analysis.

Results

Malignancy was diagnosed in 73 of 101 patients postoperatively; SDS score was significantly higher in these patients than in those with benign tumors at all timepoints: malignant/benign, 41.8/37.9 preoperatively (p = 0.004); 43.5/37.8 3 months postoperatively (p = 0.006); and 42.9/37.7 6 months postoperatively (p = 0.020). SDS scores were significantly higher in patients < 65 years old with malignancy at 3 months than at 6 months postoperatively (44.6/42.5, p = 0.046) and in patients with malignancy who underwent pancreaticoduodenectomy at 3 months postoperatively than preoperatively (43.4/41.1; p = 0.028). SDS scores moderately correlated with 8 physical symptom-related FACT-Hep items 3 months postoperatively (p < 0.05), showing low-to-moderate correlation with 16 physical symptom-related FACT-Hep items at 6 months postoperatively (p < 0.05). Multiple regression analysis of FACT-Hep symptoms significantly correlated with SDS scores revealed the following significant variables: “lack of energy” (p < 0.000) and “pain” (p = 0.018) preoperatively (R² = 0.43); “able to perform usual activities” (p = 0.031) and “lack of energy” (p < 0.000) at 3 months postoperatively (R² = 0.51); and “stomach swelling or cramps” (p = 0.034) and “bowel control” (p = 0.049) at 6 months postoperatively (R² = 0.52).

Conclusions

PC patients experience persistently high levels of depression preoperatively through 6 months postoperatively, with associated subjective symptoms including pain and gastrointestinal symptoms.

Investigating the Effects of the Progressive Muscle Relaxation-Guided Imagery Combination on Patients with Cancer Receiving Chemotherapy Treatment: A Systematic Review of Randomized Controlled Trials

BACKGROUND

Previous systematic reviews indicate that progressive muscle relaxation (PMR) and guided imagery (GI) are both effective interventions to decrease the psychological impact and to alleviate the adverse events in cancer patients undergoing chemotherapy treatment. To date, no review studies have investigated the effectiveness of a combination of PMR and GI.

AIM

To systematically review the current state of knowledge regarding the effects of the PMR-GI combination on cancer patients receiving chemotherapy.

METHODS

A search for relevant records was carried out in four electronic databases (AMED, Cochrane Library, Pubmed and Scopus). After removing the duplicates 342 publications were screened and 71 were considered as potentially relevant. The flow of information of this study was in line with the PRISMA statement. Original articles investigating the application of both PMR and GI through a randomized trial on patients receiving chemotherapy were included. Those using PMR or GI alone and those combining other techniques together with PMR and GI were excluded. The trials' quality was assessed using the Jadad Scale.

RESULTS

Eight papers reporting the results of seven independent trials were finally included. All of them included only breast cancer patients, apart from a single trial using a mixed sample of breast and prostate cancer patients. Seven of the included trials reported beneficial effects on mental state (mood, anxiety, and depression) and on toxicity (nausea and vomiting). Three trials reported an effect on biomarkers (heart rate, blood pressure, cortisol, and immunity). Four trials scored three of five points on the Jadad Scale, two trials scored two points and a single trial scored zero.

CONCLUSIONS

Independent trials indicate that the PMR-GI combination is an effective way to tackle the impact of nausea and vomiting and to improve patients' mental state. However, studies involving other types of primary tumors would be useful because seven of the eight clinical trials only included breast cancer patients. Future research on the identification of potential effects on disease-related parameters (e.g., cytokines and disease-recurrence) and on patient survival is highly needed.

Impact of a patient-tailored complementary/integrative medicine programme on disturbed sleep quality among patients undergoing chemotherapy

OBJECTIVES

The present study examined the impact of a patient-tailored complementary/integrative medicine (CIM) programme on sleep quality in patients undergoing chemotherapy for breast and gynaecological cancer.

METHODS

Study participants received standard supportive care, with or without weekly CIM treatments. Disturbed sleep quality was defined as a score of ≥4 on the Edmonton Symptom Assessment Scale (ESAS) or a score of ≥3 on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Adherence to integrative care was defined as attending ≥4 CIM treatments, with ≤30 days between each session.

RESULTS

Of 388 eligible patients, 264 (68%) reported disturbed sleep quality. Baseline-to-follow up assessment (at 6 weeks) was optimal for 104 patients in the treatment group and for 76 controls, with 75 of treated patients found to be adherent to the CIM intervention. Sleep-related ESAS scores improved more significantly in treated patients (p=0.008), as did sleep-related concerns on EORTC (treatment group, p=0.026).

CONCLUSIONS

A patient-tailored CIM programme may improve sleep quality and related concerns among patients with breast and gynaecological cancer undergoing chemotherapy. Further research is needed to better understand the impact of CIM on sleep quality in this patient population.

Complementary Therapies for Symptom Management in Cancer Patients

Cancer patients are often poly-symptomatic which distressingly affects their quality of lives (QOLs). Alhough, conventional management provides adequate symptom control, yet is coupled with some limitations. Complementary therapies (CTs) have shown beneficial effects in cancer patients for symptomatic relief. The aim of this article is to provide evidence-based review of commonly used CTs for symptom management in cancer care. Hypnosis has promising evidence to be used for managing symptoms such as pain, chemotherapy-induced nausea/vomiting, distress, fatigue, and hot flashes. Guided imagery increases comfort and can be used as a psycho-supportive therapy. Meditation substantially improves psychological function, mental health, and QOL. Cognitive behavioral therapies effectively reduce pain, distress, fatigue, anxiety, and depression; and improve subjective sleep outcomes along with mood and QOL. Yoga has short term beneficial effects for anxiety, depression, fatigue, perceived stress, QOL, and well-being. T'ai Chi and qigong are beneficial adjunctive therapies for supportive cancer care, but their role in reducing cancer pain is not well proven. Acupuncture is effective for reducing treatment related side-effects, pain and fatigue. Other therapies such as massage techniques, energy therapies, and spiritual interventions have also demonstrated positive role in managing cancer-related symptoms and improve overall well-being. However, the clinical effectiveness of these therapies for symptom management in cancer patients cannot be concluded due to poor strength of evidence. Nonetheless, these are relatively free from risks and hence can be given along with conventional treatments. Only by tailoring these therapies as per patient's beliefs and preferences, optimal patient-centered holistic care can be provided.

Acupoint stimulation, massage therapy and expressive writing for breast cancer: A systematic review and meta-analysis of randomized controlled trials

Researches have accumulated using non-pharmacologic interventions including acupoint stimulation, massage therapy and expressive writing to manage breast cancer-related symptoms. Results from randomized controlled trials (RCTs) can get contradictory.

OBJECTIVE

A systematic review and meta-analysis were conducted to determine the effects on the quality of life, negative emotions and disease-related symptoms among women with breast cancer.

METHODS

Two independent researchers performed a structured search using data sources including MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, PubMed and PsychINFO from the beginning of time until the first week of January 2015. A total of 23 acupoint stimulation, massage therapy and expressive writing RCTs were included in the review.

RESULTS

The study showed that no single intervention could be put under the spotlight exhibiting an overall effective result on all measured outcomes; however, looking into each one in detail shows different results in specific outcomes. Among the three interventions, acupoint stimulation has a treatment effect for general pain (MD=-1.46, 95% CI=-2.38 to -0.53) and fatigue (MD=-2.22, 95% CI=-3.68 to -0.77), massage therapy has a treatment effect for anxiety (MD=-0.50, 95% CI=-0.77 to -0.24), and expressive writing has a treatment effect for quality of life (MD=7.18, 95% CI=0.38 to 13.98). The measurement other outcomes showed either ineffective or equivocal results.

CONCLUSION

Non-pharmacologic interventions including acupoint stimulation, massage therapy and expressive writing have an effect on a middle-age woman with breast cancer. However, because of limitations, the seemingly promising results should be interpreted with caution.
