Comfort and anxiety levels of women with early stage breast cancer who receive radiotherapy

An Investigation of the Effect of Virtual Reality on Alleviating Anxiety in Patients With Breast Cancer Undergoing Radiation Therapy: A Randomized Controlled Trial

PURPOSE

The aim of this study was to evaluate the anxiety-reducing effects of virtual reality (VR) on patients with breast cancer undergoing adjuvant radiation therapy (RT).

METHODS AND MATERIALS

This randomized controlled trial was conducted among patients with breast cancer receiving RT at a single institution. Of 196 enrolled and randomized patients, 97 were assigned to a VR explanation group (intervention) and 99 were assigned to the standard-of-care group (control). Anxiety levels were measured using the Amsterdam Preoperative Anxiety and Information Scale (APAIS) as the primary endpoint and the State-Trait Anxiety Inventory (STAI) and Linear Analogue Scale Assessment (LASA) as secondary endpoints. Knowledge of the RT procedure, patient satisfaction, and time spent for counseling were also assessed.

RESULTS

Intervention significantly reduced patient anxiety immediately, not only on the primary endpoint, APAIS, but also on the STAI and LASA anxiety scales. Specifically, in the intervention group, there were immediate reductions of 26.0%, 16.1%, and 55.8% for APAIS, STAI, and LASA, respectively, whereas in the control group, the respective reductions were 8.1%, 8.5%, and 13.7%. Among the 3 anxiety scales, long-term anxiety reduction was observed only when anxiety was measured by LASA. Subgroup analyses showed that the effect on anxiety did not differ based on the physician, baseline anxiety level, use of hormone therapy, or health literacy. The intervention also significantly improved knowledge of the RT procedure (81.9/100 vs 76.8/100; P = .006) and patient satisfaction with the explanation manner (6.56 vs 5.72; P < .001) compared with the control group.

CONCLUSIONS

Immersive VR applied to the current procedure reduces anxiety during RT planning for patients with breast cancer. Further research is necessary to investigate the long-term effects of VR on anxiety.

Factors affecting anxiety and depression in young breast cancer survivors undergoing radiotherapy

PURPOSE

This study examined anxiety and depression, and their relationship with symptom assessment, uncertainty, social support, and stress in young breast cancer patients receiving radiotherapy.

METHODS

This is a descriptive quantitative study. The participants were 126 patients under 50 years of age with breast cancer undergoing radiotherapy.

RESULTS

The anxiety and depression levels were higher among those who were married (t = -2.318, p = .022), non-religious (t = 4.510, p = .005), and had a higher monthly income (F = 2.840, p = .041). The hierarchical regression analysis model included symptom assessment, uncertainty, social support, and stress, and accounted for about 49% of the variance in anxiety and depression (F = 7.688, p < .001). Additionally, uncertainty (β = 0.304, p = .001) and stress (β = 0.308, p = .001) were significant predictors of anxiety and depression.

CONCLUSIONS

Based on the results of this study, nursing interventions are needed to reduce uncertainty and stress in order to reduce anxiety and depression in young breast cancer patients undergoing radiation treatment.

First day of radiotherapy for women with breast cancer: predictors of anxiety

PURPOSE

Radiotherapy treatment may generate anxiety, especially on the first day of treatment. This study aimed to identify potential predictors of radiotherapy-related anxiety in women  with breast cancer before treatment initiation, in terms of treatment concerns and trait anxiety.

METHODS

This transversal study included 94 patients from one Radiation Oncology Department, who had been diagnosed with primary breast cancer and who had been prescribed external radiotherapy for the first time. Patients completed a Treatment Concerns Questionnaire and the State-Trait Anxiety Inventory (STAI) before the  first treatment session.

RESULTS

Women identified radiation involved in the procedure and treatment efficacy as major concerns surrounding radiotherapy. No significant differences were found between patients with higher and lower state anxiety scores, or by age, level of education, cancer treatment protocol used, prior information given about treatment, or report of doubts before treatment initiation. In the final model, the combination of trait anxiety (49.1% of the total variance) with two treatment-related concerns, regarding radiation and the duration of treatment (plus 10.8% of the total variance), significantly predicted treatment-related anxiety experienced on the first day of treatment.

CONCLUSION

Our findings highlight the need to identify women with moderate or higher levels of trait anxiety before radiotherapy initiation and to provide them with a more approach to personalized care, adjusted to their specific concerns and susceptibility to anxious reactions. Effective education sessions involving the discussion of specific treatment concerns, and anxiety coping strategies training should be developed and applied in initial interactions with breast cancer patients.

Mindfulness-based stress reduction for women diagnosed with breast cancer

BACKGROUND

Breast cancer is the most common cancer in women. Diagnosis and treatment may drastically affect quality of life, causing symptoms such as sleep disorders, depression and anxiety. Mindfulness-based stress reduction (MBSR) is a programme that aims to reduce stress by developing mindfulness, meaning a non-judgmental, accepting moment-by-moment awareness. MBSR seems to benefit patients with mood disorders and chronic pain, and it may also benefit women with breast cancer.

OBJECTIVES

To assess the effects of mindfulness-based stress reduction (MBSR) in women diagnosed with breast cancer.

SEARCH METHODS

In April 2018, we conducted a comprehensive electronic search for studies of MBSR in women with breast cancer, in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and two trial registries (World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov). We also handsearched relevant conference proceedings.

SELECTION CRITERIA

Randomised clinical trials (RCTs) comparing MBSR versus no intervention in women with breast cancer.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Using a standardised data form, the review authors extracted data in duplicate on methodological quality, participants, interventions and outcomes of interest (quality of life, fatigue, depression, anxiety, quality of sleep, overall survival and adverse events). For outcomes assessed with the same instrument, we used the mean difference (MD) as a summary statistic for meta-analysis; for those assessed with different instruments, we used the standardised mean difference (SMD). The effect of MBSR was assessed in the short term (end of intervention), medium term (up to 6 months after intervention) and long term (up to 24 months after intervention).

MAIN RESULTS

Fourteen RCTs fulfilled our inclusion criteria, with most studies reporting that they included women with early breast cancer. Ten RCTs involving 1571 participants were eligible for meta-analysis, while four studies involving 185 participants did not report usable results. Queries to the authors of these four studies were unsuccessful. All studies were at high risk of performance and detection bias since participants could not be blinded, and only 3 of 14 studies were at low risk of selection bias. Eight of 10 studies included in the meta-analysis recruited participants with early breast cancer (the remaining 2 trials did not restrict inclusion to a certain cancer type). Most trials considered only women who had completed cancer treatment.MBSR may improve quality of life slightly at the end of the intervention (based on low-certainty evidence from three studies with a total of 339 participants) but may result in little to no difference up to 6 months (based on low-certainty evidence from three studies involving 428 participants). Long-term data on quality of life (up to two years after completing MBSR) were available for one study in 97 participants (MD 0.00 on questionnaire FACT-B, 95% CI -5.82 to 5.82; low-certainty evidence).In the short term, MBSR probably reduces fatigue (SMD -0.50, 95% CI -0.86 to -0.14; moderate-certainty evidence; 5 studies; 693 participants). It also probably slightly reduces anxiety (SMD -0.29, 95% CI -0.50 to -0.08; moderate-certainty evidence; 6 studies; 749 participants), and it reduces depression (SMD -0.54, 95% CI -0.86 to -0.22; high-certainty evidence; 6 studies; 745 participants). It probably slightly improves quality of sleep (SMD -0.38, 95% CI -0.79 to 0.04; moderate-certainty evidence; 4 studies; 475 participants). However, these confidence intervals (except for short-term depression) are compatible with both an improvement and little to no difference.In the medium term, MBSR probably results in little to no difference in medium-term fatigue (SMD -0.31, 95% CI -0.84 to 0.23; moderate-certainty evidence; 4 studies; 607 participants). The intervention probably slightly reduces anxiety (SMD -0.28, 95% CI -0.49 to -0.07; moderate-certainty evidence; 7 studies; 1094 participants), depression (SMD -0.32, 95% CI -0.58 to -0.06; moderate-certainty evidence; 7 studies; 1097 participants) and slightly improves quality of sleep (SMD -0.27, 95% CI -0.63 to 0.08; moderate-certainty evidence; 4 studies; 654 participants). However, these confidence intervals are compatible with both an improvement and little to no difference.In the long term, moderate-certainty evidence shows that MBSR probably results in little to no difference in anxiety (SMD -0.09, 95% CI -0.35 to 0.16; 2 studies; 360 participants) or depression (SMD -0.17, 95% CI -0.40 to 0.05; 2 studies; 352 participants). No long-term data were available for fatigue or quality of sleep.No study reported data on survival or adverse events.

AUTHORS' CONCLUSIONS

MBSR may improve quality of life slightly at the end of the intervention but may result in little to no difference later on. MBSR probably slightly reduces anxiety, depression and slightly improves quality of sleep at both the end of the intervention and up to six months later. A beneficial effect on fatigue was apparent at the end of the intervention but not up to six months later. Up to two years after the intervention, MBSR probably results in little to no difference in anxiety and depression; there were no data available for fatigue or quality of sleep.

Which technique of positioning and immobilization is better for breast cancer patients in postmastectomy IMRT, single-pole or double-pole immobilization?

Purpose

Our purpose was to explore which immobilization is more suitable for clinical practice in postmastectomy intensity modulation radiotherapy, the single‐pole position or the double‐pole position?

Methods

Patients treated with postmastectomy intensity modulation radiotherapy were eligible. They were selected randomly for single‐pole position or double‐pole position. Dose–volume histogram (DVH) was used to evaluate plans. After their first radiotherapy, the physicians asked a question about the comfort level of their position. The dosimetric parameters, comfort levels, and reproducibility of the two immobilization techniques were collected and analyzed after all patients had finished the whole radiotherapy.

Results

Totally, 94 patients were enrolled. Of these, 54 patients were treated with the single‐pole position, 28 (51.9%)had left‐sided lesions. While 40 patients were treated with the double‐pole position, 20 (50%) had left‐sided lesions. Patients’ characteristics in two groups were comparable. The single‐pole and double‐pole immobilizations had similar conformity (0.60 ± 0.05 vs 0.60 ± 0.06, P = 0.887) and homogeneity index (0.14 ± 0.03 vs 0.13 ± 0.03, P = 0.407). Compared to single‐pole position, double‐pole position typically increased the mean dose, V₂₀, and V₃₀ of heart (P < 0.05). Moreover, patients in the single‐pole group felt more comfortable than another group (P < 0.05). There was no difference in reproducibility between the two groups (P > 0.05).

Conclusions

Single‐pole position seems to be more comfortable and can reduce dose coverage to heart. Both devices allow for reproducible setup and acceptable dosimetry.

Quality of life and anxiety in women with breast cancer before and after treatment

Objectives:

to determine the quality of life and anxiety in patients with breast cancer and the changes they experience after treatments.

Method:

prospective study. Breast cancer statistics (n=339, confidence=95%, accuracy= ± 5.32%). The quality of life questionnaires (QLQ) used were QLQ C-30 and QLQ Br23, and the State-Trait Anxiety Inventory (STAI) was used for anxiety. A multivariate analysis was performed to identify variables associated with baseline quality of life and anxiety as well as pre- and post-treatment differences. Authorization was obtained from the Ethics Committee, and informed consent was provided by all patients.

Results:

the baseline quality of life dimensions with the lowest score were future prospects (46.0/100) and sexual enjoyment (55.7/100). The dimensions with the highest score were body image (94.2/100) and role (93.3/100). The most disturbing symptoms were insomnia, fatigue and concern about hair loss. After treatment, the dimensions of physical function, role, body image, financial concerns and symptomatology worsened, whereas emotional function and future prospects improved. Severe anxiety presented as a state (48.6%) and as a trait (18.2%). The highest baseline state anxiety was associated with married-widowed status and anxiolytic medication. The greatest trait anxiety was associated with an inactive work situation, anxiolytic medication, breast swelling and advanced stage at diagnosis. After treatment, anxiety significantly decreased.

Conclusions:

After treatment, the quality of life score was positively modified, while state and trait anxiety decreased.

Relationship Between Socio-Demographic Features, Work-Related Conditions, and Level of Anxiety Among Turkish Primary Health Care Workers

The purpose of this study was to investigate the relationship among Turkish primary health care workers’ socio-demographic characteristics, working conditions, and anxiety. A cross-sectional study was conducted with 88 of 103 (85.4%) eligible health care workers from the city of Mugla participating. The participants’ average age was 31 years, 85.2% were university graduates, 30.7% were nurses, and 64.8% had been working between 11 and 20 years at the time of the study; 93.6% worked 8 hours each day or less. State anxiety scores for males ( p = .016), health care workers age 31 or older ( p = .035), nurse participants ( p = .043), and individuals who had worked 11 or more years ( p = .044) were significantly higher than the rest of the sample; however, trait anxiety scores for participants who did not work overtime and were not scheduled for shift work were significantly higher ( p = .033 and p = .004, respectively) than the rest of the sample. According to the logistic regression analysis, risk factors for anxiety included being male and older than 31 years.
