To examine the effect of two interventions on emotion suppression and psychological distress in patients with non-metastatic breast cancer
Each group met for eight weeks for two hours each week. There were three groups:
PHASE OF CARE: Transition phase after active treatment
Three-arm RCT with measurement at baseline (T0), 4 months (T1), 8 months (T2), and 12 months (T3)
No difference in groups except for cancer duration, which was longer in SEG group and shorter in the BMS group (p = 0.01). There were no significant improvements in anxiety or depression. Emotion suppression: significantly decreased in the first four months for SEG and BMS with no change in control group. Perceived stress: No change in control or SEG but significant decreases in first four months in BMS group.
SEG resulted in moderate decrease in emotional suppression at 4 and 8 months, with participant perceived benefits; method is applicable for increased expression of emotions. SEG minimal effect on anxiety, depression and perceived stress.
BMS showed no effect on anxiety and depression (d = 0.38–0.46) and little (small to medium d = 0.07–0.2) effect on emotional suppression and perceived stress.
No significant effectiveness of the named therapies: SEG or BMS
Conduct large-scale research with sufficient power to examine effectiveness of these therapies. Learn and apply these therapeutic approaches. Use full-scale 52-week protocol for expression support therapy.

To evaluate the effectiveness of low light therapy (starlight therapy) on symptoms at end of life, including anxiety, agitation, dyspnea, restlessness, insomnia, and pain.
Patients observed or reporting symptoms were enrolled in the study and low light therapy (starlight therapy) was applied for two hours with observations at baseline, 30 minutes, and at two hours.
Prospective trial of use of low light therapy in patients observed or self-reporting symptoms
Lux meter (measuring light levels), vital signs, adapted Assessing Distressing Symptoms STAR Symptom Scale and Questionnaire, outcome measurement tools (physiological symptoms)
Respiratory rate significantly reduced from a rate of 23.91 at baseline to a mean rate of 18.63 (p < 0.01) at 30 minutes and a mean rate of 17.88 (p < 0.0001) at two hours. Heart rate also significantly reduced from a mean of 98.45 at baseline to a mean of 84.9 at 30 minutes (p < 0.01) and 84.55 at two hours (p < 0.0001). End-of-life symptoms as measured on the STAR symptom scale were noted and presence of moderate or severe symptoms were totaled with significantly fewer patients with presence of moderate or severe symptoms at both 30 minutes and two hours for agitation (p = 0.003 for 30 minutes, p < 0.0001 for two hours), anxiety (p < 0.0001 for 30 minutes, p < 0.0001 for two hours), restlessness (p < 0.001 for 30 minutes, p < 0.0001 for two hours), and sleep (p = 0.002 for 30 minutes, p < 0.0001 for two hours), with no significant reduction in numbers of patients with moderate or severe pain or dyspnea seen at any other time point.
Low light therapy shows some promise symptoms of agitation/anxiety/restless/sleep in patients with terminal illness in hospice, but further research needed given the small sample size, prospective design, limited patient population, and specific setting.
An oncology nurse should be aware that noninvasive interventions such as low light therapy show promise for reductions in certain symptoms at end of life, but more research is warranted for recommendation for wider populations/settings.

To investigate the effect of intraoperative lidocaine infusion on postoperative cognitive function after craniotomy for supratentorial tumor resection
Patients in the experimental group received lidocaine (2%) as an IV bolus (1.5 mg/kg) after anesthesia induction followed by infusion at 2 mg/kg per hour throughout surgery (lidocaine group). Patients in the control group received normal saline at the same rate (normal saline group).
PHASE OF CARE: Active anti-tumor treatment
Double-blind randomized controlled trial of lidocaine versus placebo with repeated measures
There were no significant demographic or clinical differences between the lidocaine group and normal saline group at baseline. Postoperative neuropsychological-cognitive decline was defined as a decline greater than or equal to the preoperative standard deviation on two or more of the four tests (MMSE, IMCT, HRSD, and HAMA). Using this criteria, there were a greater proportion of patients with postoperative decline in the saline group as compared to the lidocaine group at 1 week after surgery (40% versus 16%, p < 0.05), but this was not statistically significant after correcting for multiple comparisons. There were no significant differences between the groups in the incidence of postoperative cognitive decline at 1 day, 1 month, 3 months, or 6 months. Additional analyses using less stringent criteria for cognitive decline on MMSE and IMCT alone also did not reveal any differences.
Intraoperative lidocaine had no effect on cognitive functioning after supratentorial tumor resection.
There is insufficient evidence to support the use of intraoperative lidocaine to reduce the incidence of cognitive decline after supratentorial tumor surgery.

To evaluate anxiety levels in patients with CML undergoing bone marrow biopsy who were exposed to the odor of C.aurantium essential oil versus those who were not
C. aurantium is an essential oil of the Citrus genus. In this study, participants were exposed to the essential oil odor via electronic diffuser. The study was divided into three groups. The first group received oral diazepam (10 mg), the second group was exposed to C. aurantium, and the third group was exposed to a placebo vaporized solution. In the second and third groups, exposure was 30 minutes long.
PHASE OF CARE: Multiple phases of care
Randomized controlled trial
State-Trait Anxiety Inventory (STAI) was used for subjective measurements. This is a self-reported anxiety scale. Physiological measurements including systolic and diastolic blood pressures, heart rate, and respiratory rate were also assessed.
The groups that received diazepam and exposure to C. aurantium both showed significant decrease in systolic blood pressure (p < 0.05). The group exposed to C. aurantium experienced significant decrease in heart rate (p < 0.001) as well as significant differences in anxiety levels as reported on the STAI-S before and after the treatment when analyzed by Wilcoxon test (p < 0.001).
Findings suggest that C. aurantium may potentiate anxiolytic effects in patients with CML undergoing bone marrow biopsy.
C. aurantium and other anxiolytic essential oils may be considered as nonpharmacologic tools for the reduction of anxiety in patients with cancer, although much more research is needed in more diverse patient populations.

Structural distress screening and supportive care for patients with lung cancer on systemic therapy: A randomised controlled trial. European Journal of Cancer, 72, 37–45.
To examine effects of routine distress screening and referral on patient’s mood, satisfaction, and quality of life
Patients were randomized to receive the routine screening or usual care. Study assessment were done at outpatient visits weeks 1, 7, 13, and 25 after study entry. Usual care involved medical care and psychosocial care by the physician; psychosocial care was not integrated and referrals for psychosocial care were based on physician judgment. There was no structural distress screening. In the screening group, patients completed the Distress Thermometer and Problem List at each clinic visit. For scores of 4 or greater, patients were offered referral to an appropriate provider.
PHASE OF CARE: Active anti-tumor treatment
RCT
There were no differences between groups in study outcome results for quality of life, depression, or anxiety. There were no differences in hospitalizations or ED visits between groups.
Findings did not show that routine distress screening and provision of care based on screening had any effect.
This study did not show any significant differences in patient outcomes due to implementation of routine distress screening and associated supportive care referral.

As relevant to this PEP topic: 60% (3 of 5) studies that examined anxiety supported decreased general anxiety among patients who participated in yoga therapy. The other two large studies also showed less anxiety in this population, although it was divided into state and trait anxiety. A decrease in depression and depressive symptoms was reported in all of the studies reviewed that looked at psychosocial benefits related to yoga, which supports other meta-analyses stating that adding yoga therapy to traditional breast cancer treatment can decrease depression in these patients.
Evidence supports that yoga can have benefits on both physical and psychosocial quality of life in patients with breast cancer, including a decrease in both anxiety and depression. Additional research should aim to assess long-term effects of yoga in this population.
Yoga is an evidence-based intervention that may reduce anxiety and depression in patients with cancer. Recommending yoga to patients with breast cancer undergoing active treatment may be beneficial, particularly for those with high levels of anxiety and/or depression.

PHASE OF CARE: Active anti-tumor treatment
APPLICATIONS: Pediatrics
Doses of yoga ranged from 1 to 18 sessions and frequency ranged from every three weeks to three times per week. Some were delivered as group classes and two included caregivers. Some interventions included psychoeducation and supportive interventions. Some provided instructions and recommendations for practice at home. Attrition rates ranged from 8%-56%. Adherence to planned sessions ranged from 59%-88% and where measured, adherence to home practice ranged from 50%-80%. In non-random studies, improvements in anxiety, depression, mood, cognition, sleep, and fatigue were reported. Several RCTs reported improvement in distress, depression, anxiety, and multiple treatment-related side effects and symptoms.
Evidence suggests that yoga can be helpful to adults undergoing cancer treatment. There is insufficient evidence to draw any conclusions regarding benefit for children.
There is not a lot of strong evidence to show benefits of yoga for various symptoms for patients during cancer treatments due to individual study design limitations. Existing evidence suggests that yoga may be helpful for anxiety, depression, sleep, and cognitive impairment. Further well-designed research to explore these areas is needed. Yoga is a relatively low-risk intervention that may be helpful and could be suggested to patients who are interested and able to participate.

APPLICATIONS: Elder care, palliative care
As relevant to these PEP topics, yoga primarily improved health-related quality of life, fatigue, and sleep disturbances. Evidence suggests short-term effects of yoga compared with psychosocial/education interventions on depression, anxiety, and fatigue. During active cancer treatment, yoga improved depression, anxiety, and fatigue compared with no therapy or psychosocial/educational interventions. After therapy, yoga showed effects on health-related quality of life, fatigue, and sleep disturbances. The studies were not robust enough to measure effects of yoga more than five years after diagnosis or in the metastatic breast cancer population.
Evidence supports that yoga can have benefits on health-related quality of life in patients with breast cancer, including a decrease in anxiety, depression, and fatigue. Additional research is needed to assess the effectiveness of yoga more than five years from diagnosis and in the metastatic population.
Yoga has been shown to be an evidence-based intervention which can improve health-related quality of life and symptoms, including depression, anxiety, and fatigue, in women with non-metastatic breast cancer at all stages of treatment, up to five years postdiagnosis.

To evaluate differences in psychological states between breast cancer survivors who do practice yoga and those who do not
This case-control exploratory study consisted of two groups. The first was breast cancer survivors doing regular yoga (more than six months of regular yoga practice in the last year), and the second was women who had no prior yoga experience (or less than three yoga sessions in the last year). Yoga experience was self-reported by the participants, including their regular yoga schedule. No changes to their yoga practice or schedule were made by the researchers.
PHASE OF CARE: Late effects and survivorship
Case-control exploratory study
Perceived stress scale, Spielberg’s state and trait anxiety questionnaire, Beck’s depression inventory, General Health Questionnaire, WHO QOL Questionnaire-BREF
Analysis revealed significantly decreased anxiety, depression, and stress in the group that participated in yoga (p < 0.001). This group also reported better general health and overall quality of life (p < 0.001). Higher income predicted lower anxiety and depression scores, while better reported sleep quality predicted lower stress and depression scores as well.
This study supports yoga as an intervention to decrease anxiety, depression, and stress in breast cancer survivors.
Yoga is an evidence-based intervention that may reduce anxiety and depression in patients with cancer. Although this study only examined breast cancer survivors, discussing yoga as a method to decrease anxiety and depression may be an appropriate option for many patients with cancer.

Authors attempted to correlate core elements of interventions with outcomes. Overall, there were very few studies that had any common combinations of core elements, so this analysis could not be done. Overall, studies suggested that psychoeducational interventions may be beneficial for relieving symptoms of anxiety and depression. The content, elements, structure duration and frequency of interventions across studies were varied. Many interventions labeled as self-management education did not include components related to self management.
Psychoeducational interventions appear to be beneficial for symptoms of anxiety and depression. It is not possible to determine the specific components of these types of interventions that are most helpful.
Psychoeducational interventions of various types can be beneficial in reducing patients’ anxiety and depressive symptoms.
