A high stress profile is associated with severe pain in oncology patients receiving chemotherapy

Analysis of the link between stress and cancer: implications for patient support

In a world where oncological diseases remain a serious problem for many people, the study of stress management and the provision of psychological support to prevent and treat oncological diseases are becoming increasingly relevant. The purpose of the article is to identify stress mechanisms that affect the human body and provoke the development of cancer.Additionally, it seeks to investigate the global scope of the stress-cancer connection. The methods used in the study include generalisation, analysis, synthesis, and systematisation. The study found that chronic stress can affect the immune system, neurological activity, and other processes contributing to cancer development. In addition, the study has managed to shed light on the mechanisms of stress impact on oncology, including oxidative stress and replication stress, as stimuli that threaten the normal functioning of the human body. A support program for patients with oncological diseases was developed, which included assessment, psychoeducation, methods of stress reduction, and post-treatment support for patients with oncological diseases or those predisposed to them. The study found that the introduction of stress reduction programs for cancer patients is an important step in improving their well-being and treatment outcomes.

COVID-19 pandemic stress and cancer symptom burden

OBJECTIVES

In a sample of patients with cancer (n=1145) who were assessed during the height of the COVID-19 pandemic, latent profile analysis was used to identify subgroups of patients with distinct stress profiles and to evaluate for differences in demographic and clinical characteristics and symptom severity scores among these subgroups.

METHODS

Patients completed measures of cancer-specific and COVID-19 stress, global stress, social isolation, loneliness, depression, state and trait anxiety, morning and evening fatigue, morning and evening energy, sleep disturbance, cognitive function, and pain. Latent profile analysis was used to identify subgroups of patients with distinct stress profiles. Differences among the subgroups in study measures were evaluated using parametric and non-parametric tests.

RESULTS

Using clinically meaningful cut-off scores for the stress measures, four distinct stress profiles were identified (ie, none class (51.3%); low stress and moderate loneliness class (24.4%), high stress and moderate loneliness class (14.0%), and very high stress and moderately high loneliness class (high, 10.3%)). Risk factors associated with membership in the high class included: younger age, lower annual household income, lower functional status and higher comorbidity burden. The two worst stress profiles reported clinically meaningful levels of all of the common symptoms associated with cancer and its treatments.

CONCLUSION

Findings from this study, obtained prior to the availability of COVID-19 vaccines and anti-viral medications, provide important 'benchmark data' to evaluate for changes in stress and symptom burden in patients with cancer in the postvaccine era and in patients with long COVID-19.

The Effects of Massage Therapy in Decreasing Pain and Anxiety in Post-Surgical Patients With Breast Cancer: A Systematic Review and Meta-Analysis

Background

Massage therapy is an effective non-pharmacological intervention in treating pain and anxiety of patients with cancer. Prior studies have reviewed the benefits of massage therapy in patients with breast cancer undergoing chemotherapy, radiation, and other patient-specific cancer treatments. What has yet to be examined is the effects of massage therapy on the pain and anxiety of patients with breast cancer after surgery.

Objective

: The purpose of this systematic review and meta-analysis was to examine the effect of massage therapy on post-surgical pain and anxiety in patients with breast cancer.

Methods

Systematic searches were performed using databases PubMed, CINAHL, and Medline (EBSCO), with no date constraint through September 30, 2023, to identify randomized control trials, randomized pilot, and quasi-experimental studies. The database searches retrieved 1205 titles, and after screening, 7 studies were chosen for full analysis using Cohen's d, 95% Confidence Interval (CI), and effect size. The heterogeneity of the studies was calculated in the meta-analysis using Cochran's Q equation.

Results

Massage therapy techniques reported were massage therapy, classic massage, reflexology, myofascial release, and myofascial therapy, and were performed at day 0 up to 16 weeks post-surgery. Massage therapy decreased pain and anxiety for patients in the massage group. Analyses showed a positive effect size using massage therapy as an intervention for pain and anxiety in women with breast cancer post-surgery. Overall effect size for pain was 1.057 with a P-value of <.0001, and overall effect size for anxiety was .673 with a P-value of <.0001.

Conclusion

The current evidence in this study reflects that massage therapy is effective as a non-pharmacological tool in decreasing post-surgical pain and anxiety in women with breast cancer.

Proposing and evaluating a model of depression, stress, resilience and spirituality in relation to pain in women with breast cancer: Investigating the mediating role of mindfulness

BACKGROUND

Pain experience is one of the most common symptoms of women with breast cancer receiving chemotherapy. It may cause physical and psychological problems and interfere with the treatment process.

AIMS

This study aimed to examine the relationship between depression, stress, resilience and spirituality on the pain symptoms of breast cancer patients during chemotherapy and explore the potential mediating role of mindfulness in this association.

METHOD

Two hundred and forty women with breast cancer receiving chemotherapy from Shiraz University Hospital, were selected and evaluated by a purposive sampling method. The research instruments were Perceived Stress Scale, Beck Depression Questionnaire-2, Mindfulness, Resilience, Spirituality and Pain Questionnaires. The obtained data was analyzed by SPSS software and MPLUS using Spearman correlation coefficient and path analysis.

RESULTS

Based on the findings of direct path analysis, depression, stress, and spirituality showed a significant relationship with mindfulness, but resilience had no significant relationship with mindfulness (p < 0.01). Furthermore, depression, stress, resilience, and mindfulness showed a significant relationship with pain, while spirituality had no significant relationship with pain (p < 0.01). Finally, indirect path analysis revealed mindfulness is a significant mediator of stress and pain (p < 0.05).

CONCLUSIONS

The present study suggested a model can be useful in better understanding of the psychological components affecting pain in breast cancer patients, after and during their treatments. It also provided an effective framework to develop and investigate pain-focused and non-pharmacological interventions.
