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

Effects of psychological intervention on negative emotions and psychological resilience in breast cancer patients after radical mastectomy

Breast cancer (BC)is the most common malignant tumor in women, and the treatment process not only results in physical pain but also significant psychological distress in patients. Psychological intervention (PI) has been recognized as an important approach in treating postoperative psychological disorders in BC patients. It has been proven that PI has a significant therapeutic effect on post-operative psychological disorders, improving patients' negative emotions, enhancing their psychological resilience, and effectively enhancing their quality of life and treatment compliance.

A structured laughter yoga therapy program on patients with chemotherapy-induced nausea and vomiting: A randomized clinical trial

Objetive

Chemotherapy is a prevalent cancer treatment, often accompanied by debilitating side effects such as nausea and vomiting. This study explores the potential effectiveness of laughter yoga, a combination of exercise and voluntary laughter, in alleviating chemotherapy-induced nausea and vomiting.

Methods

This two-group randomized clinical trial was conducted on 69 cancer patients undergoing chemotherapy at the Reza Chemotherapy and Oncology Center, Mashhad, Iran, in 2018. Patients were randomly divided into intervention and control groups. Both groups received routine self-care training, with the addition of four 20-min to 30-min laughter yoga sessions held immediately before one of their chemotherapy appointments for the intervention group only. Nausea and vomiting were assessed using the Morrow Assessment of Nausea and Emesis questionnaire at two stages, before and after the intervention. Data were analyzed with Chi-square, Independent-t, Mann-Whitney, Wilcoxon, and McNemar tests using Statistical Package for the Social Sciences (SPSS).

Results

The mean age of patients in the intervention group was 49.0 ± 9.6 years, while in the control group, it was 45.2 ± 12.6 years. The intragroup comparison showed a statistically significant decrease in the severity and duration of nausea in the intervention group and a statistically significant increase in the severity and duration of nausea in the control group from pre-test to post-test (P < 0.05). The intergroup comparison showed no statistically significant difference between the two groups in terms of vomiting conditions.

Conclusions

Laughter yoga demonstrates promise in improving chemotherapy-induced nausea, suggesting its potential recommendation for managing this distressing side effect. Further research is warranted to explore its broader application in cancer care.

Assessment of the Impact of Yoga on the Quality of Life of Breast Cancer Patients: A Systematic Literature Review

Patients with breast cancer (BC) typically undergo multimodal treatment over an extended period and deal with a wide range of symptoms that severely impair their overall quality of life (QoL) and prognosis. Concern about the health-related QoL of persons diagnosed with cancer as well as the calibre of care they receive is increasing every day. This study aims to assess the impact of yoga on the QoL of patients with BC. PRISMA guidelines served as the foundation for the methodologies used to identify the studies. A total of 480 records were found using PubMed/Medline and Google Scholar databases. A final set of 22 studies was assessed for the work based on the exclusion and inclusion criteria and study eligibility. Yoga has a moderate effect on BC patients. Pranayama has been shown to have a positive effect on improving the QoL. The study observed that yoga was more useful during actual treatment for cancer than after completion. The various randomised controlled trials (RCT) and meta-analysis included in this study believe that yoga has a positive effect. However, the outcomes of various studies do not support this point completely. According to the safety information that is currently available, yoga is not associated with severe adverse outcomes. There is no concrete evidence that establishes the role of yoga as one of the alternative medicines in treating BC patients after chemotherapy. More clinical trials are needed to investigate the advantages of yoga in the overall improvement of QoL in BC patients.

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.

The Effect of Psychological Interventions on the Quality of Life in Women with Fibromyalgia: A Systematic Review

Fibromyalgia refers to a painful type of rheumatological clinical syndrome, and its prevalence varies from 0.7% to 6.6%. This syndrome is associated with different physical and psychological symptoms, which ultimately leads to a decline in women's quality of life. A wide range of pharmacological and non-pharmacological interventions are conducted to mitigate these symptoms and improve the quality of life. Therefore, the present study aims to investigate the effect of psychological interventions on the quality of life in women with fibromyalgia. This systematic review with comprehensive search was carried out on Google Scholar, Scopus, PubMed, Web of Science, Science Direct, Cochrane Library, PsycINFO, and Scientific Information Database (SID), databases using the suitable keywords, and a total of 3125 articles from 2000 to 2019 were retrieved. Finally, the quality of 16 experimental and semi-experimental clinical trials was evaluated using the Jadad scale. The psychological interventions affecting the quality of life in women with fibromialgia included cognitive-behavioral therapy and behavioral therapy, coping strategies training, mindfulness, acceptance and commitment treatment, hypnosis, meditation, music therapy, short-term psychodynamic psychotherapy and writing emotions. The results of the study showed that except four studies, the studies generally improved the quality of life and reduced the symptoms in women with fibromyalgia. The results of the study suggest that most psychological interventions affect the quality of life in women with fibromyalgia. Therefore, besides pharmacological therapy, psychological interventions can be used by health-care providers to reduce the symptoms of fibromyalgia and improve the quality of their life.
