Bourke, L., Thompson, G., Gibson, D. J., Daley, A., Crank, H., Adam, I., . . . Saxton, J. (2011). Pragmatic lifestyle intervention in patients recovering from colon cancer: a randomized controlled pilot study. Archives of Physical Medicine and Rehabilitation, 92, 749–755.

Study Purpose

To investigate the feasibility of an intervention aimed at increasing exercise participation and improving dietary behavior in survivors of colon cancer and obtain preliminary data on the effect of the intervention on fatigue, exercise, and dietary outcomes.

Intervention Characteristics/Basic Study Process

Patients were randomly assigned to intervention or standard care control groups. The 12-week intervention included supervised and home-based exercise and dietary advice. During the first six weeks, the experimental group attended two group supervised exercise sessions of 30 minutes of aerobic exercise. Participants were asked to continue the same time of activities at home once a week during the same period and were asked to keep an exercise log. During the last six weeks, participants attended a supervised session once a week and were to perform two weekly home-based exercise sessions. Participants were given a dietary advice information pack and periodically attended healthy eating seminars encouraging reduction in saturated fat, increased fiber intake, reduction in refined carbohydrates, and limited alcohol intake.

Sample Characteristics

  • The sample was comprised of 18 survivors of colon cancer.
  • Mean age was 69 years (range 52–80); 66.6% of patients were female and 33.3% were male.
  • Of the patients, 83.3% had undergone surgery and one-third had received chemotherapy.
  • Average time from the end of treatment was slightly greater than 16 months.

Setting

  • Single site
  • Outpatient
  • United Kingdom

Phase of Care and Clinical Applications

Patients were undergoing the transition phase after initial treatment.

Study Design

This was a randomized, controlled trial that was single-blinded for some outcome measures.

Measurement Instruments/Methods

  • Godin Leisure Score Index for exercise behavior
  • Functional Assessment of Cancer Treatment–Fatigue scale (FACT-F)
  • Functional Assessment of Cancer Treatment–Colorectal scale (FACT-C) for quality of life
  • Skeletal muscle fatigability assessed via electromyogram (EMG) signal analysis

Results

There was an overall 90% attendance rate at supervised exercise sessions and a 77% attendance rate at dietary seminars. Of those in the intervention group, 66.6% returned exercise logs, and among these, there was a 94% rate of adherence to independent aerobic exercise for 25 to 30 minutes. There was no significant difference between groups in exercise behavior. Fatigue scores improved significantly in the intervention group (p = 0.005) compared to controls. There was a significant increase in dietary fiber intake (p = 0.044), with no other differences in dietary habits. Compared to controls, there were significant improvements in chair sit to stand performance (p = 0.003) and aerobic exercise tolerance (p = 0.01).

Conclusions

Combined supervised group and home-based individual exercise with dietary education was shown to be feasible and demonstrated preliminary positive effects on fatigue and dietary fiber intake.

Limitations

  • The study had a small sample size, with less than 30 participants.
  • Standard care was not described.
  • There is no information about other interventions or symptoms that might affect outcomes.
  • The study design lacked an attentional control.
  • There was a 6% dropout rate.
  • There was a relatively limited time frame of follow-up.
  • Given no difference between groups in exercise behavior overall, findings suggested that the group aspect with seminars and supervised exercise sessions may have been the important difference.

Nursing Implications

Findings suggested that an intervention combining some group supervised exercise and some home-based exercise is feasible and can be effective in reducing fatigue. Further research in this area is warranted as researchers attempt to determine the most effective ways to provide exercise interventions that patients will adhere to. The combination of some group periodic supervised sessions may improve patient motivations to adhere to a program, given the relatively low dropout rate seen here. This study was performed after completion of cancer treatment.

Botrel, T.E., Clark, O.A., Clark, L., Paladini, L., Faleiros, E., & Pegoretti, B. (2010). Efficacy of palonosetron (PAL) compared to other serotonin inhibitors (5-HT3R) in preventing chemotherapy-induced nausea and vomiting (CINV) in patients receiving moderately or highly emetogenic (MoHE) treatment: Systematic review and meta-analysis. Supportive Care in Cancer, 19, 823–832.

Purpose

To analyze randomized, controlled trials (RCTs) comparing a single IV palonosetron dose to other serotonin antagonists for prevention of chemotherapy-induced nausea and vomiting (CINV)

Search Strategy

Databases searched were Embase, LILACS, MEDLINE, SCI, CENTRAL, National Cancer Institute Clinical Trials service, Clinical Trials Register of Trials Central, American Society of Clinical Oncology, and American Society of Hematology and European Society for Medical Oncology abstracts.

Search keywords were palonosetron, random, chemotherapy, clinical trial, meta-analysis, practice guideline, randomized controlled trial, and review.

Studies were included in the review if they

  • Were RCTs with parallel design that compared a single IV dose of palonosetron with other 5-HT3 receptor antagonists (RAs) in patients receiving chemotherapy.
  • Reported on patients receiving moderately or highly emetogenic chemotherapy regimens.

Literature Evaluated

Initially, 324 references were identified. Five trials were used for final analysis. Two independent reviewers extracted study data and evaluated study quality and risk of bias. No specific methodology for this was described.

Sample Characteristics

  • The final sample was five studies involving 2,057 patients.
  • Study sample sizes ranged from 50 to 667 participants.
  • In three studies, use of corticosteroids was not allowed, and, in one study, corticosteroids were used concomitantly in a few patients.
  • In all but one study, the primary endpoint was complete response during the acute phase.

Results

  • Overall from 0 to 120 hours, palonosetron was superior in the prevention of vomiting (relative risk [RR] = 0.79; confidence interval [CI] = 95%, 0.72–0.88; p < 0.00001).
  • Palonosetron was more effective than other 5-HT3 RAs in preventing acute vomiting (RR = 0.76; CI = 95%, 0.66–0.88, p = 0.0002) as well as late vomiting (RR = 0 0.76; CI = 95%, 0.68–0.85; p < 0.00001).
  • Substantial heterogeneity was found (p < 0.05); however the superiority of palonosetron remained when one trial was removed from analysis with reduction in heterogeneity.
  • In the study that used corticosteroids, no difference was found between palonosetron and other 5-HT3 RAs.

Conclusions

  • Palonosetron was more effective than other 5-HT3 RAs for the prevention of acute and delayed CINV, when the drug regimen did not include corticosteroids.
  • No difference in efficacy was found when other 5-HT3 RAs were used in combination with a corticosteroid.

Limitations

  • Despite guidelines and recommendations that include the use of steroids, four out of the five trials included did not incorporate these.
  • No subgroup analysis could be done between moderately and highly emetogenic chemotherapy regimens; therefore, it is not known if different CINV prevention regimens have different efficacy based on this factor.

Boström, A., Lindman, H., Swartling, C., Berne, B., & Bergh, J. (2001). Potent corticosteroid cream (mometasone furoate) significantly reduces acute radiation dermatitis: Results from a double-blind, randomized study. Radiotherapy and Oncology, 59, 257–265.

Study Purpose

To determine if use of mometasone furoate (MMF), a corticosteroid cream could reduce intensity of erythema in acute radiation dermatitis

Intervention Characteristics/Basic Study Process

Patients were randomized to receive tubes of either MMF cream 0.1%  or an emollient cream as a placebo control. Patients were instructed to apply the cream on the irradiated area twice a week up to 24 Gy and then once daily for the rest of treatment and three weeks after completion of radiation therapy. All patients in both study groups also applied the emollient cream over the radiated area once daily throughout the entire study period.

Sample Characteristics

  • The study sample (N = 50) was comprised of female patients with breast cancer who had undergone breast-conserving surgery.
  • Mean age was 58 years for the MMF group and 60 years for the control group.
  • All had a World Health Organization performance status of 0.
  • A 5 MV photon beam was delivered in 2 Gy fractions for a total dose of 54 Gy.

Setting

The study took place in Uppsala, Sweden.

 

Study Design

The study used a randomized double-blind controlled design.

Measurement Instruments/Methods

  • Skin reaction was measured with a seven-point grading scale, from 0 (no reaction) to 6 (moist desquamation) evaluated in five defined skin regions at each visit. Maximum scores were used in analysis.
  • Patients’ subjective experiences of itching, burning, and pain were measured using a visual analogue scale.
  • The Mann Whitney U test was used for all statistical comparisons.
  • A reflectance spectrophotometer was used to rate erythema. The device emits various light colors corresponding to absorption peaks of hemoglobin and melanin.
  • The intensity of emitted light as measured by a photo detector was used to provide a patient erythema index and a patient melanin index. These indexes were calculated as the mean of three assessments in each of five skin regions identified for each patient.

Results

  • The two-photon excitation was lower in the MMF group (p = 0.033)
  • The maximal skin reaction grade was lower in the MMF treated group (p = 0.011).
  • Six patients in the control group required further topical treatment because of severe subjective symptoms. Three patients in the MMF group needed further treatment of severe moist desquamation in the axilla.
  • Patients in the MMF group reported less itching and burning, but the differences were not statistically significant.

Conclusions

MMF patients showed less pronounced erythema, less itching and less burning than emollient group. MMF may provide a benefit.

Limitations

  • The study had a small sample size, with less than 100 participants.
  • Reliability of the seven-point scale was not stated, and it was not clear who was making observations.
  • There was no log for application of the creams, so compliance with the planned regimen was not clear. The study did show that two patients did forget to apply the MMF during the treatment period.
  • The study did not report if other skin regimens, such as washing, were allowed.
  • Both groups applied the control emollient cream, so it is unclear what effect this had on skin reactions

Bortolussi, R., Zotti, P., Matovic, M., Morabito, A., Bertuzzi, C., Caserta, M., . . . Roscetti, A. (2016). A phase II study on the efficacy and safety of procedural analgesia with fentanyl buccal tablet in cancer patients for the placement of indwelling central venous access systems. Supportive Care in Cancer, 24, 1537–1543. 

Study Purpose

To determine the effectiveness of using fentanyl buccal tablets (FBT) to reduce pain related to placing indwelling vascular access ports in opioid-naïve patients with cancer

Intervention Characteristics/Basic Study Process

Patients were assessed on anxiety and pain preoperatively. Ten minutes prior to the procedure, 100 mcg FBT was administered. Patients were assessed postoperatively on pain during the procedure. Side effects and symptoms were monitored during, after, and four hours after the procedure. Those with anesthesia-related nausea received one metoclopramide tablet one hour prior to the procedure, and those with extreme pain during the procedure received rescue therapy of 30 mg ketorolac or 20 drops of tramadol if allergic to NSAIDS/ASA.

Sample Characteristics

  • N = 65   
  • AGE = 18 years and older
  • MALES: 29.2%, FEMALES: 70.8%
  • CURRENT TREATMENT: Not applicable
  • KEY DISEASE CHARACTERISTICS: Histologically confirmed diagnosis of cancer
  • OTHER KEY SAMPLE CHARACTERISTICS: Participants were 18 years or older, had indication for port as an inpatient, were cognitively intact, and had written informed consent. Exclusion factors: xerostomia; treatment for chronic cancer pain with opioids; history of nausea and vomiting to opioids or intolerance to fentanyl or FBT; chronic respiratory insufficiency; hepatic or renal function impairment.

Setting

  • SITE: Not stated/unknown   
  • SETTING TYPE: Inpatient    
  • LOCATION: Inpatient

Phase of Care and Clinical Applications

  • PHASE OF CARE: Active antitumor treatment
  • APPLICATIONS: Elder care

Study Design

  • Phase II pre-/poststudy design

Measurement Instruments/Methods

  • Four-point Likert-type scale for pain
  • State-Trait Anxiety Inventory Form Y (STAI-Y)

Results

  • Significantly lower perception of pain in those treated with FBT than those not treated with FBT (p = 0.0018)
  • Drowsiness reduced from after procedure to four hours post-procedure (p < 0.01)
  • Vertigo reduced from after procedure to four hours post-procedure (p < 0.02)
  • No significant findings with respect to nausea, vomiting, vital signs, and other side effects

Conclusions

Use of FBT pre-procedure to reduce pain perception is a plausible intervention for pain control in those receiving a port but is not without side effects. Further consideration to prevent or ameliorate side effects and further studies with a larger population should be considered.

Limitations

  • Small sample (< 100)
  • Risk of bias (no blinding)
  • Risk of bias (no random assignment)
  • Risk of bias (no appropriate attentional control condition)  
  • Risk of bias (sample characteristics)
  • Unintended interventions or applicable interventions not described that would influence results
  • Key sample group differences that could influence results
  • Findings not generalizable
  • These patients were compared to 2010–2011 patients, and so retrospective report and not knowing potential conditions impacting reporting is a weak area of this study

Nursing Implications

Nursing would need to be prepared for management of side effects and potential fall risk post-procedure. Side effects could require restructuring the postoperative environment to meet the needs of the patients or require follow-up beyond four hours.

Study Purpose

To evaluate the relationship between antiemetic effect and well being over four different antiemetic treatment strategies

Sample Characteristics

  • The study consisted of a total of 162 chemotherapy-naive patients with ovarian cancer.
  • All patients received similar combination chemotherapy, including cisplatin (50 mg/m2).

Setting

This study was conducted in the greater Stockholm, Sweden, area, with two gynecologic oncology wards.

Study Design

Patients were randomly admitted to one of the two hospital wards for the study. Study II was a randomized, double-blind trial on the same hospital wards.

Measurement Instruments/Methods

  • Patients completed self-assessment questionnaires the day after and two weeks after chemotherapy.
  • Presence, frequency, and intensity (on a 0–100 visual analog scale [VAS]) of nausea and vomiting was recorded. 
  • Duration of acute nausea, including time of onset and number of hours until relieved, were recorded.
  • Delayed nausea, including the number of days with any symptoms, was recorded for two weeks after chemotherapy.
  • Questionnaires were administered regarding well-being before, during, and after chemotherapy.
  • A 0–100 VAS was used to measure aspects of quality of life and well-being.

Results

  • Relief from delayed symptoms was highest in the group that received high-dose metoclopramide (2.5 mg/kg x 2), dexamethasone (20 mg x 1), lorazepam (1 mg x 2), and biperiden (1-2 mg x 3) followed by low-dose metoclopramide (20 mg x 3) orally for three days after chemotherapy.
  • Nausea intensity was lowest in the group that received ondansetron (8 mg x 3) and dexamethasone (20 mg x 1) IV during the chemotherapy day and ondansetron orally (8 mg x 3) for five days after chemotherapy.
  • Duration of acute nausea was shortest in the high-dose metoclopramide group. The high-dose metoclopramide and the ondansetron and dexamethasone groups reported better well-being.
  • Duration of acute nausea was the only variable that was significantly related to well-being in both samples.
  • Relaxation training was offered to 20 patients in the ondansetron and placebo group and 18 patients in the ondansetron and dexamethasone group; no differences were found in the studied variables.

Limitations

  • Some patients received a benzodiazepine, but no comparison regarding effect can be made.
  • All patients had ovarian cancer, were in the same department, and were treated with similar chemotherapy.

Study Purpose

To provide information about organizational experience with use of pegfilgrastim following dose intensive chemotherapy for solid tumors in pediatric patients with cancer.

Intervention Characteristics/Basic Study Process

Medical records of patients receiving myelosuppressive therapy supported with pegfilgrastim were reviewed (cases from 2007–2008). By protocol, pegfilgrastim was given in the outpatient clinic by subcutaneous injection at 0.1 mg/kg to a maximum does of 6 mg 24–48 hours after completion of chemotherapy. Complete blood counts (CBCs) were routinely monitored  every 7–10 days during therapy cycles, then every 2–5 days until neutrophil recovery. Analysis was limited to the first four courses of chemotherapy.

Sample Characteristics

  • 47 patients completed 176 courses of chemotherapy.
  • Median age was 13 years, with a range of 2 months to 23 years.
  • Females made up 53% of the sample; males made up 47%
  • Key disease characteristics included Hodgkins disease, rhabdo myosarcoma, neuroblastoma, osteosarcoma, and Ewing sarcoma.
     

Setting

  • Single site
  • Outpatient
  • Seattle, WA

Phase of Care and Clinical Applications

  • The phase of care was active antitumor treatment.
  • The application was for pediatrics.

Study Design

Retrospective descriptive

Measurement Instruments/Methods

  • Severe neutropenia was classified as an absolute neutrophil count (ANC) of less than 200 mm3
  • Neutrophil recovery was an ANC greater than 200 mm3
  • Febrile neutropenia was defined as severe neutropenia with temperature of 38.3ºC or higher with hospitalization and parenteral antibiotic therapy.
     

Results

There were no significant adverse effects observed with pegfilgrastim. Leukocytosis was observed in 73% of patients, with no adverse sequelae. Severe neutropenia occurred in 57% of chemotherapy courses, and febrile neutropenia was seen in 28% of courses. Course delay occurred in 9% of courses, with a mean duration of two days of delay.

Conclusions

 This report provides evidence regarding the safety and efficacy of pegfilgrastim among a pediatric cancer population.

Limitations

  • Risk of bias (no control group) 
  • Risk of bias (no blinding)  
  • Risk of bias (no random assignment)
  • Unintended interventions or applicable interventions not described that would influence results
  • Key sample group differences that could influence results
  • Retrospective study design with associated risk of bias in results. 
  • No information is provided regarding any other prophylactic medications for prevention of infection in this population.

Nursing Implications

Findings suggest that pegfilgrastim is effective and can be safety given to pediatric patients.

Study Purpose

To evaluate a method of mechanical lymphatic drainage using the RAGodoy apparatus

Intervention Characteristics/Basic Study Process

Lymphedema was confirmed with lymphoscintigraph and volumetry and defined as a difference in arm volumes of more than 200 ml. Patients had a one-hour session with the RAGodoy mechanical apparatus, which provides 15–25 elbow bending and stretching exercises per minute. Pre- and post-treatment volumetry was taken.

Sample Characteristics

  • The study sample was comprised of female patients with breast cancer who were experiencing arm lymphedema.
  • The sample age range was 42–86 years.

Setting

The study took place at a single outpatient site in Brazil.

Study Design

The study used a prospective trial design.

Results

The reduction in the volume was an average of 59.2 ml (p < 0.001). In two cases, there was an increase in volume with the intervention. In the remaining 23, there was a decrease in volume. It appeared that for those where there was an increase, the patients did not fully allow the device to passively work.

Conclusions

Passive mechanical exercise for lymphatic drainage may be helpful in the management of lymphedema

Limitations

  • The sample size was small, with less than 30 participants.
  • The report was brief with limited data and sample characteristics provided.
  • The apparatus appeared to have been developed by the authors, so potential for bias must be considered.
  • The study reported on single use only; repeated or longer-term use of the approach is unknown.

Nursing Implications

Use of a device for provision of passive limb exercise in the management of lymphedema requires further study.

Purpose

STUDY PURPOSE: To explore the effectiveness of pharmalogic and nonpharmalogic agents in treating hot flashes in breast cancer survivors

TYPE OF STUDY: Systematic review

Search Strategy

DATABASES USED: Medline and EMBASE
 
YEARS INCLUDED: 1990–July 2006
 
INCLUSION CRITERIA: Included randomized, controlled trials with large samples; subheadings menopause, breast tumor, breast cancer, menopause, and hot flashes
 
EXCLUSION CRITERIA: Pilot studies excluded

Literature Evaluated

TOTAL REFERENCES RETRIEVED: 14 studies, 7 complementary alternative medicine (CAM) and 7 pharmacologic (nonhormonal)
 
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Although the authors stated that only select large sample studies were included, they included a miscellanea of randomized studies and did not describe study quality.

Sample Characteristics

  • FINAL NUMBER STUDIES INCLUDED = 4 nonpharmacologic and 22 pharmacologic
  • TOTAL PATIENTS INCLUDED IN REVIEW = 1,930 patients (779 nonpharmacologic; 1,151 pharmacologic) 
  • SAMPLE RANGE ACROSS STUDIES: 47–347
  • KEY SAMPLE CHARACTERISTICS: Breast cancer survivors, clinical characteristics not specified and length of follow-up not described

Phase of Care and Clinical Applications

PHASE OF CARE: Transition phase after active treatment
 
APPLICATIONS: Elder care

Results

Seven randomized, controlled studies of complementary alternative medicines (CAM) with soy, black cohosh, or vitamin E. Soy was not more effective than placebo. No significant difference existed in experimental groups with black cohosh, and a small difference was observed in only one study with vitamin E, so it is unlikely clinical significant.
 
Seven randomized, controlled studies of clonidine. Transdermal clonidine was associated with constipation, drowsiness, dryness, and itching episodes. Antidepressants like venlafaxine were significant in decreasing hot flashes with less side effects with a 75 mg dose than a 150 mg. Paroxetine (20 mg) was statistically significant, but nausea was reported. Fluoxetine and sertraline were better than placebo in controlling hot flashes. Other symptoms related to hot flashes, such as sleeplessness, depression, loss of libido, and anxiety, were better controlled with antidepressants. These drugs are associated with some side effects, such as anorexia, nausea, dry mouth, somnolence, and headache.
 
A large controlled study showed that gabapentin (900 mg per day) was highly effective in decreasing hot-flash disturbances but was also associated with somnolence, dizziness, rash, edema, and fatigue. Six hormonal interventional trials were reviewed and had conflicting results for breast cancer recurrence. The authors noted selection bias with several of them.

Conclusions

CAM therapies and vitamin E appear to have some effect, but data are limited. Gabapentin and some of the newer antidepressants were the most effective, with some side effects. These studies had small to moderate sample sizes, which makes overall effectiveness difficult to establish.

Limitations

  • Limited search
  • No quality evaluation
  • High heterogeneity
  • Older article (2007)
  • Hormone replacement therapy was not accepted by women

Nursing Implications

Nurses need to know the negative effects of hormonal agents on safety. Nonpharmacologic agents, such as soy phytoestrogens, black cohosh, and vitamin E, appear to be ineffective and limited because of the methodological limitations of studies. Gabapentin and some of the newer antidepressants were the most effective but still have side effects.

Study Purpose

Evaluate the efficacy of venlafaxine versus gabapentin for hot flashes in breast cancer survivors

Intervention Characteristics/Basic Study Process

Patients were randomly assigned to receive venlafaxine for 4 weeks, then after a 2-4 week washout receive gabapentin for 4 weeks, or to have the medications in the reverse order.    Patients were given venlafaxine 37.5 mg daily for 7 days and then 75 mg daily for 21 days.  Gabapentin was given at 300 mg at bedtime for 3 days, then 2 times daily for 3 days, then 3 times daily for 22 days.  Patients completed a hot flash diary daily.  At baseline, and at the end of each study period, they completed a symptom rating and study questionnaires.

Measurement Instruments/Methods

  • SF -36
  • Hot flash severity on VAS
  • Hot flash diary
  • Quality of Life Questionnaire

Results

Only 38 patients completed all 4 weeks of both drugs, and 12% of those initially entered dropped out.  Of patients who provided data regarding drug preference, the majority preferred venlafaxine (p = .01).   There were no significant differences between treatments on hot flash outcomes, and hot flash scores were reduced from baseline in both groups (p<.001).  Venlaxafine was associated with loss of appetite (p<.01), nausea ( p = .02), constipation (p =.05), and fewer negative mood changes (p = .003).  Gabapentin was associated with more dizziness ( p = .005) and increased appetite (p<.001).  Hot flash scores in all subjects increased during the 2-4 weeks off therapy.  There were no serious adverse effects of the medications.

Conclusions

  • Both gabapentin and venlaxafine reduced hot flash severity in these patients. 
  • Each medication was associated with (differing) side effects. 
  • More patients preferred venlaxafine.

Limitations

  • Small sample (< 100)
  • Risk of bias (no blinding)
  • Subject withdrawals ≥ 10%
  • Other limitations/*explanation  It is not clear if patients or observers were blinded to treatment assignments. Subjects not stratified based on age.

Nursing Implications

The findings suggest that either venlafaxine or gabapentin can be effective in reducing hot flash symptoms in breast cancer survivors.  More patients preferred venlafaxine.  Both drugs have side effects.

Purpose

The objective of this study was to discuss the evidence for our present understanding of the symptom of dyspnea and unanswered questions regarding the genesis and management of cancer-related breathlessness.

Search Strategy

Databases searched were MEDLINE, CINAHL, and EMBASE (1966-2006). 

Search keywords were breathlessness, cancer, lung cancer, cancer, dyspnea/dyspnoea, intervention, management, and nonpharmacological.

Studies were included in the review if they were double-blind, randomized, randomized- controlled, or placebo-controlled trials, case reports, or uncontrolled trials that

  • Defined the experience of breathlessness
  • Assessed the effectiveness of pharmacologic and nonpharmacologic management to relieve breathlessness in patients with advanced cancer.

Older reviews were excluded.

Literature Evaluated

Volume of studies retrieved, methods of study evaluation, and specific information about studies retrieved were not provided. Authors reviewed articles they deemed important to the science of dyspnea in patients with cancer and its management from the perspective of content experts.

Sample Characteristics

The sample characteristics were not described.

Results

  • Listening to the patient and caregiver’s experience with dyspnea and creating an individualized breathlessness plan may be helpful in alleviating anxiety-related dyspnea.
  • A fan directed at the face is inexpensive and showed efficacy in one study and may be ideal to manage a breathlessness crisis.
  • Relaxation and diaphragmatic breathing techniques may aid in breathlessness and anxiety.
  • Noninvasive ventilation may have a role in dyspnea symptom control in select patients but has been ill-defined.
  • Safety of using opioids across populations of breathless patients with cancer needs to be tested by adequately powered epidemiologic studies.
  • No controlled trials support use of phenothiazines or benzodiazepines for management of breathlessness, but authors suggest use of these agents as adjuncts to other therapies or when symptoms are refractory to other therapies.
  • A fully powered multi-center randomized controlled international study is underway to test the efficacy of oxygen in reducing dyspnea.
  • Heliox is best used after therapies have been rigorously applied and failed to elicit reduction in dyspnea.
  • The use of antidepressants or inhaled furosemide for breathlessness in patients with advanced cancer requires systematic investigation.

Conclusions

Progression of the science of understanding breathlessness in patients with cancer requires collaboration between the research and clinical practice of cardiology, oncology, palliative medicine, social sciences, and physiology. Because dyspnea is a dynamic process that may manifest differently in unique populations and situations, possible variables should be well delineated and interventions should be varied to learn the most information about management of this complex symptom.

Limitations

This review provides a summary of the evidence in multiple interventions, but the report is limited due to lack of provision of study sample characteristics and information regarding the search strategy and methods of evaluation of the strength of the evidence. These limit the level of confidence in findings and conclusions.

Nursing Implications

The first step to managing breathlessness is careful assessment of the patient and investigation of potential correctable etiologies of breathlessness. The interview should include a patient and caregiver accounting the dyspnea and its triggers, intensity, aggravating factors, alleviating factors, and response to pharmacologic and nonpharmacologic interventions.
