Eyigor, S., Uslu, R., Apaydın, S., Caramat, I., & Yesil, H. (2018). Can yoga have any effect on shoulder and arm pain and quality of life in patients with breast cancer? A randomized, controlled, single-blind trial. Complementary Therapies in Clinical Practice, 32, 40–45.
To examine the effects of yoga on shoulder and arm pain, quality of life (QOL), depression, and physical performance in patients with breast cancer
A 10-week Hatha yoga program was evaluated in this study. Hatha yoga is a mind-body exercise program of breathing exercises, flexibility, and relaxation components. The program in this study was supervised by a certified trainer and the session was taught at a beginner level. Sessions lasted one hour and were offered two days per week. All study participants (intervention and control) received education about cancer, lymphedema, and coping with ADLs. This included a booklet with information on exercises to stimulate lymph circulation. All participants were asked to practice these exercises twice a day.
PHASE OF CARE: Transition phase after active treatment
Randomized controlled trial (RCT) with a usual care control group. Study outcomes were assessed by personnel blinded to the study assignment.
Visual analog scale for pain, European Organization for Research and Treatment of Cancer Quality of Life Core 30 (EORTC QLQ-C30) questionnaire, Beck Depression Inventory, 6-minute walk test, and evaluation of lymphedema. Measures were completed pre- and post-treatment. Study measures were also completed at 2.5 months post-treatment, but because most of the control group did not show up for their follow-up visit, data for the control group were not included in the analysis.
The two study groups did not differ significantly on demographic characteristics, types of breast cancer treatment, and baseline study measure scores. The yoga group demonstrated a significant improvement in pain severity from baseline to post-treatment for shoulder (p = 0.01) and arm (p = 0.01) pain; however, there was no significant difference between the yoga and control groups in regard to pre- and post-treatment pain. The yoga group’s improvement in pain severity was maintained at 2.5 months post-treatment (p = 0.01). There was no difference in depression, 6-minute walk, and QOL scores between groups from baseline to post-treatment. The yoga group demonstrated significantly improved QOL from baseline to 2.5 months post-treatment for functional (p = 0.01) and symptom (p = 0.03) scores, and improvement in their 6-minute walk time (p = 0.04). No evidence of worsening of lymphedema was found in either study group.
It is unclear if the yoga intervention truly relieved the shoulder and arm pain of the women with breast cancer since the control group also experienced a decrease in pain severity from baseline to 10 weeks. Shoulder and arm pain may normally decrease over time for this patient population. However, the Hatha yoga program appears to be a safe intervention which could be recommended if patients are interested in pursuing it.
Although Hatha yoga was not found to be more effective than usual care in relieving shoulder and arm pain, it appears to be a safe form of exercise. In addition, women in this study liked it as evident by the 95.5% adherence rate. Nurses should have an understanding of Hatha yoga so, if patients ask about it, they can explain that it is a safe form of exercise but its effectiveness in relieving pain needs to be studied further.

To determine whether performing a preoperative ultrasound-guided transversus abdominis plane block is an effective pain control measure for laparoscopic surgery for colorectal cancer.
After anesthesia induction, the patient received 0.5 ml/kg of either 0.25% bupivacaine or normal saline, depending on their predetermined group assignment. Pain was assessed at rest and when coughing 1 hour after surgery, on post-op day 1, post-op day 2, and post-op day 3.
Randomized, double-blind, placebo-controlled trial
Pain was measured using the numeric rating scale (NRS). Cumulative opioid use was recorded from post-anesthesia recovery, post-op day 1, post-op day 2, and post-op 3.
Insignificant differences between the treatment group and control group exists when comparing post-op pain and opioid use.
When comparing the treatment group and control group, the differences in the postoperative pain assessments was not significant enough to support that receiving a transversus abdominis plane (TAP) block provides superior benefits.
Small sample (< 100)
The purpose of this study was to determine whether performing a preoperative ultrasound-guided transversus abdominis plane block is an effective pain control measure for laparoscopic surgery for colorectal cancer. No differences were seen between the treatment and control group. Based on this study a transversus abdominis plane block requires additional research prior to being recommended in this indication.
Mohamed, S.A.B., Abdel-Ghaffar, H.S., Kamal, S.M., Fares, K.M., & Hamza, H.M. (2016). Effect of topical morphine on acute and chronic postmastectomy pain: What is the optimum dose? Regional Anesthesia and Pain Medicine, 41, 704–710.
To determine if using a different morphine amount in a morphine/bupivacaine combination would be more effective in pain management in patients after a radical mastectomy for breast cancer.
Registered clinical trial with 90 patients allocated to receive 10 ml plain bupivacaine 0.5% plus either 5, 10, or 15 mg morphine diluted with saline 0.9% to 20 ml and topically to mastectomy site prior to closing. The three groups were compared for the following: time to first postoperative analgesia; IV patient-controlled analgesia (PCA) morphine consumption; pain scores; hemodynamics; sedation; adverse events in first postoperative 48 hours; and Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scores in first and third postoperative months. Each patient participated in two study phases: an initial two-day treatment phase (48 hours post-op), phase 1, followed by a one- and three-month follow-up, phase 2. All clinical staff and patients were blinded to treatment group assignment.
PHASE OF CARE: Active anti-tumor treatment
Prospective, randomized, double-blind comparative study.
Visual analog scale (VAS), analgesia time, cumulative morphine consumption in first 48 hours, LANSS pain scale
There was a significant difference in analgesia-free time between the three groups. Morphine 15 mg had no patients requiring postoperative analgesics in the first 48 hours compared to 8 patients (27%) in the morphine 10 mg group and 19 patients (63%) in the morphine 5 mg group (p < 0.002). Regarding the time to analgesia use, the morphine 5 mg group was 7.31 hours (SD = 3.12) versus 14 hours (SD = 3.54) in the morphine 10 mg group (p < 0.000).
The morphine 15 mg group had the lowest LANSS recorded score in the first postoperative month when compared to the morphine 5 mg and 10 mg groups (1.1 [SD = 0.37] versus 5.76 [SD = 3.26] versus 4.73 [SD = 2.87], respectively) (p < 0.0001).
The increase in topical morphine (specifically up to 15 mg) in combination with bupivacaine, when compared to lower doses of morphine, has shown a decrease in postmastectomy pain through the reduction of analgesic use within 48 hours after surgery as well as lower LANSS scores within the first postoperative month.
15 mg topical morphine with bupivacaine may decrease postoperative pain and reduce the rate of PMPS.

To compare the efficacy of tetrodotoxin (TTX) to placebo in patients with pain secondary to advanced cancer or treatment related to treatment of advanced cancer.
Patients with moderate to severe cancer pain for at least two weeks or longer were randomized to receive a dose of TTX 30 µg or placebo twice daily at least six hours apart for four consecutive days. Participants were then seen on days 5, 8, and 15 in clinic for safety and efficacy evaluations and then on a weekly basis for evaluation by phone or in clinic until pain returned to baseline level.
Multi-center, randomized, double-blind, placebo-controlled, parallel-design trial
Brief Pain Inventory form completed, patient diary
Clinical benefit of TTX over placebo with estimate effect size of 16.2% (p = 0.046) after adjustment with Holm method, p value was nominally significant for two primary endpoints but not at the prespecified two-side 5% level. Average analgesic response was 57.6 days with TTX compared to placebo at 9.9 days; however, when pain was combined with QOL, there was not a statistically significant difference between those treated with TTX and those with placebo.
TTX administration provides a potential option for uncontrolled moderate to severe cancer pain in patients with advanced cancer that is a non-opioid. TTX provides a different approach to pain via the mechanism of action. However, this drug does not come without side effects/potential adverse effects and, while clinical significance has been demonstrated, this is a modest benefit. The pain reduction was only nominally statistically significant and because of statistical penalties for multiplicity, the study is not considered statistically positive. Therefore, additional study is needed to determine the usefulness of TTX for clinical practice, particularly in those who require high doses of opioids to manage their pain.
Other limitations/explanation: Conflict of interest: funded by Wex Pharmaceuticals; several doctors received operational funding, Dr. Hagen received honorarium, and some of the authors are employees or consultants for Wex Pharmaceuticals. Patients could be on existing pain regimens, unsure if fixed dosing or not
Patients would have to receive via subcutaneous injection. In the study, there were no fatalities and seemed to have a favorable benefit/risk profile. Non-opioid option, although mishandling could cause devastating consequences (TTX can cause paralysis and be fatal in high doses). Patients on high doses of opioids are poor candidates for TTX.

EXCLUSION CRITERIA: No specific exclusion criteria.
TOTAL REFERENCES RETRIEVED: 37
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Criteria used to evaluate: Pain experience, patient satisfaction, and patients’ communication skills and decision making.
FINAL NUMBER STUDIES INCLUDED: 44
TOTAL PATIENTS INCLUDED IN REVIEW: 6,308
SAMPLE RANGE ACROSS STUDIES: 30-970
KEY SAMPLE CHARACTERISTICS: Patients with cancer
PHASE OF CARE: Multiple phases of care
Pain experience: 85% of the studies reported that PEP (Pain Education Programs) significantly improved knowledge and beliefs, 52% of studies showed a statistically significant reduction in pain intensity when using PEP, but none of the studies (except one) showed that the intervention had any clear benefits on QOL.
Patient satisfaction: 90% of patients believed that PEP was helpful and 78% said that PEP made them more involved in pain management.
Patients’ communication skills and decision making: Communication with clinicians was the most frequently developed behavior, and those patients who scored higher in active communication reported better pain relief and fewer barriers to pain management.
Research indicates a growing interest in therapeutic education of patients with cancer pain. PEP objectives have shifted from a focus on improving patients’ knowledge about pain management to enhancing their communication skills and attitudes. Additional research is warranted to better evaluate PEP effectiveness.
PEP has been proven to increase patient knowledge of pain management, so it would be wise to increase training for nurses to conduct these interventions properly.
Guinigundo, A.S., Maxwell, C.L., Vanni, L., Morrow, P.K., Reiner, M., Shih, A., . . . Blanchard, E. (2018). A randomized, single-blind study evaluating the effect of a bone pain education video on reported bone pain in patients with breast cancer receiving chemotherapy and pegfilgrastim. Pain Management Nursing, 19, 693–706.
To investigate the effect of bone pain education on pegfilgrastim-related bone pain in patients with breast cancer receiving chemotherapy and pegfilgrastim. Patients were either shown a general video or specific bone pain video and then bone pain was assessed using patient surveys that asked about bone pain severity and location, medications usage, and information from adverse reporting.
Patients were randomized 1:1 to view either a generalized education video on chemotherapy side effects or a video on bone pain following chemotherapy and pegfilgrastim.
Randomized single-blind study
Patient-reported maximum bone pain was similar in both groups. General versus specific C1 3.2 versus 3.5 (p = 0.3479); across all cycles, 4.1 versus 4.6 (p = 0.2196). Other measures of bone pain were also similar between groups.
Bone pain was highest in C1 and then decreased and remained stable in subsequent cycles. Bone pain medication usage was also similar between the two groups with the highest usage in C1.
The only area that showed significance was in the 65-75 age group. Maximum bone pain for general video was 2.9 versus 4.6 (p = 0.0599); mean bone pain was 1.3 versus 2.6 (p = 0.0220) and AUC was 5.3 versus 10.9 (p = 0.018).
The bone pain-specific education did not improve patient’s perception of bone pain reported in this patient population. However, this study did provide information on the prevalence, timing, severity, and location of pegfilgrastim-related bone pain. This may help focus future research on treatments for bone pain.
The major nursing implication is that pain is highest in C1. It is important to educate patients so they do not stop pegfilgrastim treatments due to pain. They need to know the amount of pain decreased is subsequent cycles. Education must always be individualized to be effective. Videos do not replace one-on-one teaching, but new educational methods need to be developed. More research is needed in different patient populations and on specific treatment experiences.

STUDY PURPOSE: To summarize the evidence-base of psychological interventions for women with metastatic breast cancer by mode of delivery and to synthesize data regarding core intervention elements and context factors.
TYPE OF STUDY: Systematic review
DATABASES USED: Medline, PsycINFO, CINAHL, SCOPUS
YEARS INCLUDED: Inception to May 2016
INCLUSION CRITERIA: Articles published or in press in a peer-reviewed journal between database inception to May 2016. Intervention targeted adult woman with a diagnosis of MBC or recurrent breast cancer. Studies including woman with MBC as part of a larger sample with other cancers if data could be extracted about MBC patients. The therapies were psychotherapeutic. Outcomes included survival, distress, coping, QOL, or somatic symptoms. All studies were RCT, quasi-RCT, or feasibility RCT in English.
EXCLUSION CRITERIA: Grey literature
TOTAL REFERENCES RETRIEVED: 740
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Meta-analysis (PRISMA) and a review protocol was developed.
FINAL NUMBER STUDIES INCLUDED: 15 RCTs across 23 articles
TOTAL PATIENTS INCLUDED IN REVIEW: 1,638
SAMPLE RANGE ACROSS STUDIES: 37 to 235
KEY SAMPLE CHARACTERISTICS: Age, years since MBC diagnosis, English speaking, race, partnership, education, employment
PHASE OF CARE: Multiple phases of care
APPLICATIONS: Palliative care
Overall interventions improved distress in 8 of 13 RCTs, coping in 4 of 5 RCTs, and pain in 4 of 5 RCTs. No evidence of survival benefit was found. For remaining outcomes the evidence was either insufficient or too mixed to draw conclusions. Group programs had the strongest evidence base for efficacy. Individual and low-intensity therapy had insufficient evidence to form conclusions. Group interventions had longest intervention duration and lowest uptake and adherence. Low-intensity interventions had shortest duration and highest uptake and adherence. Disparities in uptake, adherence, and reach were evident with demographic profiles of age, race, language, and partnered woman (young, White, English-speaking, married women).
There remains a parity of psychological interventions for women with MBC. Those that exist have an inconsistent evidence base across the range of patient-reported outcomes. Further research is needed to evaluate accessible delivery formats that ensue efficacy as well as uptake and adherence. There were only five new articles from the last systematic review in 2013.
More research is needed on the psychological therapies used in MBC patients in regards to survival, distress, coping, QOL, pain, fatigue, and sleeping, all of which contribute to depression. There is little research on this population and their psychologic concerns, particularly in minority populations. It is important that nurses reach a broader range of women with MBC. Research is also needed on how to deliver more accessible evidence-based interventions.

STUDY PURPOSE: To review in literature the effectiveness of sympathetic blocks in clinical trials. Both, neurolytic blocks of sympathetic as celiac plexus block (CPB) and superior hypogastric plexus block (SHPB), used for visceral abdominal pain in patients with pancreatic and gynaecologic cancer
TYPE OF STUDY: Systematic review
DATABASES USED: MedLine, Embase, and Cochrane Central Register of Controlled Trials
YEARS INCLUDED: Through February 2014
INCLUSION CRITERIA: Trials, both; neurolytic blocks of sympathetic as celiac plexus block (CPB) and superior hypogastric plexus block (SHPB), compared to analgesia or placebo, adult cancer patients and English language
EXCLUSION CRITERIA: Double publications, other clinical indications related, if only complications from sympathetic blocks reported
TOTAL REFERENCES RETRIEVED: 121
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Eligible trials were analyzed using the GRADE system
FINAL NUMBER STUDIES INCLUDED: 27 clinical trials
TOTAL PATIENTS INCLUDED IN REVIEW: Not specified
SAMPLE RANGE ACROSS STUDIES: Sample range from 20 to 137
KEY SAMPLE CHARACTERISTICS: Pancreatic cancer for the CPB and pelvic pain related to gynecologic cancer for SHPB all of them requiring analgesia for their pain
PHASE OF CARE: Not specified or not applicable
APPLICATIONS: Palliative care
CPB versus analgesia significantly decreased pain intensity, use of opioids, and reported less side-effect and better quality of life. SHPB versus morphine was more effective in only one RCT with 50 patients with gynecologic cancer that resulted in decrease in pain and less morphine.
Both, neurolytic blocks techniques, are sure and with few complications. Both are effective to reduce pain and to decrease use of opioids, less data is available from SPHB. Individual complete assessment in each patient is needed before deciding the technique to be done.
No evidence can indicate the use of one or the other of the neurolytic blocks. Although celiac plexus block (CPB) seems recommended for pancreatic cancer pain, best timing for the technique is still uncertain. For superior hypogastric plexus block (SHPB) only after personalized evaluation in each case.

STUDY PURPOSE: Review the available evidence in literature to determine the effectiveness on the use of peripheral nerve blocks to treat cancer pain in adult patients.
TYPE OF STUDY: Systematic review
DATABASES USED: PubMed, EMBASE, and Cochrane
YEARS INCLUDED: All available data through February 2014
INCLUSION CRITERIA: No experimental studies of effectiveness of peripheral nerve blocks, adult patients with chronic cancer pain, data includes pain level outcomes, English language.
EXCLUSION CRITERIA: Double publications, management of postoperative pain, studies involving non-cancer patients, lack of pain assessment, experimental studies.
TOTAL REFERENCES RETRIEVED: 155
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Only case reports were used in the systematic review. No randomized controlled trials were retrieved.
FINAL NUMBER STUDIES INCLUDED: 16
TOTAL PATIENTS INCLUDED IN REVIEW: 79
SAMPLE RANGE ACROSS STUDIES: The cancer diagnoses were identified, but not limited to, thoracic, tongue, renal, breast, lung, and ovarian. Some cases involved metastasis.
KEY SAMPLE CHARACTERISTICS: Patients with cancer, different diagnoses
PHASE OF CARE: Not specified or not applicable
APPLICATIONS: Palliative care
Majority of cases yielded adequate pain relief with few side effects reported.
No conclusion can be made based on the lack of formal evidence. Greater than four types of nerve blocks were included in the 16 reviews.
Although pain control is reported with peripheral nerve blocks, lack of sufficient evidence exists to support this intervention in practice based on this review.
