TOTAL REFERENCES RETRIEVED: 112 randomized clinical trials were identified. 10 excluded that did not adopt the required criteria to evaluate oral mucositis, 28 studies or conference abstracts that did not provide a detailed number of responders and non-responders, 2 trials that recruited patients with previous chemotherapy, 5 studies that only evaluated mucositis-related pain, and 10 studies with the intention of treatment. 57 studies were eligible.
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Randomization procedure, establishment of sample size, adoption of blinding in the study design, allocation of concealment if intention-to-treat analysis was followed, loss to follow-up, and dropout. Used the revised Jadad/Oxford quality scoring system to quantify study quality.

Radiotherapy-induced oral mucositis in patients with head and neck cancer can be debilitating. This network meta-analysis compared prophylactic treatments in patients receiving postoperative radiation with or without chemotherapy. Low-level laser therapy in addition to standard of care may be more effective in reducing oral mucositis than standard care alone.
Limited information provided in the printed lack of control for or limit use of chemotherapy; not clear what constituted low-level laser therapy or the details regarding the other treatments.
Oral mucositis has been identified as a complex process; nurses should remain astute to changes in the oral cavity with the various treatments for cancer as well as changes over time. Interventions effective with a specific cancer treatment may not be universally effective. Study results should be read with a critical review process

A randomised double blind clinical trial to assess the effectiveness of topical application of aloe vera gel versus base gel on radiation-induced mucositis in patients receiving radiation therapy for head and neck malignancy in a selected hospital in Mumbai. Nursing Journal of India, 108, 187.
This study aims to evaluate the time of onset and severity of mucositis in the treatment arm (aloe vera gel) versus the control arm in patients receiving head and neck radiation. Additionally, this study describes demographic variables that impact the severity of mucositis in patient undergoing radiation therapy of the head and neck. Secondary outcomes also included a comparison of hospitalization rates, need for analgesia, antifungals, and antibiotics, as well as nutritional support rates, rates of treatment interruption, and weight loss. Quality-of-life differences between groups was also assessed.
Randomized, double blind control study
Patients in the treatment group had later onset of mucositis (p < 0.05). The treatment group also had decreased severity of mucositis (p < 0.005). The treatment group had less weight loss and less need for supportive medications. The QOL measures were more favorable for the treatment group (p = 0.000 for OMWQ, p = 0.001 for FACT-HN). There was no difference between groups in hospitalization rates or the need for nutritional support.
There is some discrepancy about oral pain results; the text says it was better in the treatment group but the p value listed is 0.243.
The author does not tell the reader anything about the statistical testing that was done, which limits the ability to interpret the results. The tables and charts are not completely labeled so they are hard to interpret as well.
Aloe vera gel may help decrease the time to development and severity of radiation-induced mucositis in patients with head and neck cancer.

The purpose of the study was to assess the effects of subcutaneous or IV fentanyl on dyspnea in patients with advanced cancer.
Subcutaneous or IV fentanyl for breathlessness at rest or with minimal exertion for patients with (a) decline in renal function and escalating doses transdermal fenatanyl/ or other opioid, and (b) alternative to transdermal fentanyl at discharge
PHASE OF CARE: End-of-life care
APPLICATIONS: Pediatrics, elder care, palliative care
Retrospective cohort study
Breathlessness was measured on a 0-4 scale, other symptoms were measured with ESAS, MMSE/Pfeiffer, and Likert scales
Total percent of responders to fentanyl was 76%. Fentanyl efficacy was not statistically related to age, gender, cancer type, previous opioid treatment, steroid and midazolam doses, and PPS. The median fentanyl dose in responders was 25 mcg/h (interquartile range = 12–70). It was significantly related to age (37 versus 12 mcg/h, for ≤ 75 versus > 75 years, respectively; p = 0.02). There was not a significant difference between fentanyl doses of responders and non-responders. 36, 23, and 15 patients had sustained improvements in dyspnea over 48, 72, and 96 hours. Fentanyl had no significant toxicity.
Subcutaneous and IV fentanyl may be associated with dyspnea relief in patients with advanced cancer. No severe adverse effects were noted.
Subcutaneous and IV fentanyl may be related to dyspnea at rest relief in patients with advanced cancer. Additional research is need to confirm these results.

Interventions represented 18 different services. Most services enrolled people with thoracic cancer, involved palliative care staff, and comprised 4–6 contacts over 4–6 weeks. Commonly used interventions included breathing techniques, psychological support, and relaxation techniques. Meta-analyses demonstrated reductions in Numeric Rating Scale distress due to breathlessness (n = 324; mean difference (MD) = −2.30, 95% CI [−4.43, −0.16], p = 0.03) and Hospital Anxiety and Depression Scale (HADS) depression scores (n = 408, MD = −1.67, 95% CI [−2.52, −0.81], p < 0.001). Statistically non-significant effects were observed for Chronic Respiratory Questionnaire (CRQ) mastery (n = 259, MD = 0.23, 95% CI [−0.1, 0.55], p = 0.17) and HADS anxiety scores (n = 552, MD = −1.59, 95% CI [−3.22, 0.05], p = 0.06). Patients and caregivers valued tailored education, self-management interventions, and expert staff providing person-centered, dignified care. There was no observable effect on health status or quality of life, and mixed evidence around physical function.
Evidence suggests an effect of integrative palliative care on the affective domain of breathlessness, and on psychological outcomes of anxiety and depression. Services were highly valued by patients and caregivers, who appreciated the education to help them understand their breathlessness, the provision of useful self-management interventions, and the provision of expert dignified care which centered on the person. No effect on overall health status or quality of life using generic measures and mixed evidence around any effect on physical function was identified
Integrative palliative care may provide a benefit to patients with advanced cancer.

To evaluate the effects of mediation group classes on patient and caregiver self-reported symptoms
This was an observational pilot that studied participants (patients and their caregivers) attending any of the three mediation group classes offered at a comprehensive cancer center. Classes were based on Tibetan mind-body mediation tradition, and spanned either 60 or 90 minutes in length, depending on type of class—power breath, sacred sounds, or movement and breath. Instructors of each mediation class consisted of mind-body therapists with at least five years of oncology experience. Participants completed a pre- and post-class Edmonton Symptom Assessment Scale (ESAS). Because participants could attend more than one meditation class, only data from the first visit of the 142 participants was examined. Data obtained from the ESAS was used to analyze symptoms individually and as subscales.
PHASE OF CARE: Multiple phases of care
Observational pilot that analyzed self-reported symptom information from patients and caregivers attending medication classes offered at a comprehensive cancer center between May and December 2015
ESAS was completed by participants before and after classes. Symptoms of the ESAS were analyzed both globally (subscales) and individually. ESAS subscales were scored as follows:
Clinically significant reduction of an individual symptom was defined as > 1; for ESAS global distress score (GDS) > 3; for physical distress score (PHS) > 2; for psychological distress score (PSS) > 2. Higher scores represented worse outcomes for the stated symptom or subscale.
For all participants there was a clinically and statistically significant decrease (improvement) in symptom of shortness of breath (mean = -1.2; p = 0.001), global distress (-5.17, p < 0.0001), fatigue (-1.34, p < 0.0001), anxiety (-1.26, p < 0.001). For patients, there was clinically significant improvement in dyspnea (mean = -1.12; p = 0.013). No clinically significant symptom change was observed when comparing class duration (60- versus 90-minute class). There was no clinically significant difference in participant symptom burden at baseline or in score reduction by group, or by attendance of one versus two or more classes.
Group mediation class, when used in conjunction to standard of therapy, shows a possible subjective improvement in shortness of breath, global distress, well-being, fatigue, and anxiety in the oncology population, but more research is warranted.
Further research on the long-term effects and continued use of group meditation on shortness of breath is warranted.

Results showed exercise positively affected the symptoms of fatigue (p = 0.0004), pain (p = 0.02), insomnia (p < 0.0001), dyspnea (p = 0.001), and no significant effect on nausea/vomiting, loss of appetite, constipation, or diarrhea. For dyspnea specifically, only within the mixed exercise program subgroup (as opposed to resistance alone or aerobic exercise alone) was an improvement effect in favor of the intervention group found.
This study concluded that it had confirmed that exercise interventions improve fatigue, pain, and insomnia in cancer, and that it had a novel finding of a benefit of exercise on dyspnea, but showed no effect on nausea/vomiting, loss of appetite, or constipation/diarrhea. The analysis did show significant results in the areas listed previously, although it is difficult to determine generalizability given the unknown sample characteristics. The effect of exercise on dyspnea was only seen with the mixed exercise groups, and it is difficult to understand who was included in that subgroup of patients; unclear, in particular, with cancer type and phase of case. The mechanism of dyspnea in a heme malignancy patient is very different, for example, than for a solid tumor patient, and there was a highly limited number of patients with lung cancer in this study. Not knowing phase of care also limits the ability to understand who this could be applied to. More exploration of the effect of exercise on dyspnea should be undertaken to reach solid conclusions, but this analysis does suggest that the exploration is warranted.
With regard to dyspnea specifically, the nurse should be aware that there is a possibility that exercise may have an impact on dyspnea for some patients. It is unclear who these patients are, or what exercise regimens are most affected, so no clear recommendation can be provided to patients at this time based on this particular study.

Dimeo et al. (2004): After three weeks of exercises and relaxation, no significant results were noted for dyspnea, but were significant for fatigue (p = 0.67 and 0.54)
Glattki et al. (2012): In a study with pulmonary rehab measured using modified research council (MRC), the dyspnea scale was significant (p = 0.007, 0.26, SD = 0.61) for improvement in dyspnea.
Peddle-McIntyre et al. (2012): The MRC dyspnea scale was measured after 10 weeks and was not significant (pre = 1.6, SD = 0.6; post = 1.4, SD = 0.8).
Riesenberg and Lubbe (2010): The study showed significant improvements in dyspnea after four weeks of QLQ testing (p < 0.001) and also for fatigue (mean difference = -13.7).
Spruit et al. (2006): Using the BORG scale, no significant difference was found (p = 0.2969)
Overall, six studies reported statistically significant reductions in fatigue, two reported significant improvement in dyspnea, and one had significant reduction in depression.
Although there were some studies that showed that exercise interventions could possibly be effective for relief of symptoms such as dyspnea, the results were mixed, and there are unclear variations between programs and high dropout rates, so no recommendations can be made based on this particular analysis.
Nurses should be aware that there is the possibility that exercise may benefit some patients, and there is little risk of harm, but nurses should be aware that it is unclear what patients or what programs would be of benefit; therefore, no recommendations can be made at this time.

To test the effects of a specially designed strength and endurance training on the independence and quality of life (QOL) in patients with stages III/IV lung cancer while undergoing chemotherapy
Endurance training and breathing techniques were performed five days per week, and strength training was performed every other day while patients received three cycles of inpatient chemotherapy (platinum based). Endurance training consisted of walking and stair exercises. Strength training consisted of four different endurance exercises (trunk stability, leg, arm, and abdominal musculature), as well as breathing techniques (active cycle of breathing) combined with conventional physiotherapy. Control arm received conventional physiotherapy. Evaluations were conducted at baseline and after three cycles of chemotherapy.
PHASE OF CARE: Active anti-tumor treatment
Randomized controlled trial
6 minute walk test, staircase walking (number of steps), Barthel Index (primary outcome measure), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30, Modified Borg Scale
After intervention, the intervention group had a significantly higher Barthel Index (p = 0.003), indicating higher independence with ADLs. In the single scores of the EORTC QLQ-C30, the intervention group reported higher physical functioning (p = 0.025), lower hemoptysis (p = 0.019), lower pain in the arms/shoulders (p = 0.048), peripheral neuropathy (p = 0.05) and cognitive functioning (p = 0.05). There were significant differences in ability on 6 minute walk test and stair walking as well as strength capacity (all p < 0.05). The level of dyspnea decreased significantly in the intervention group while performing submaximal walking activities.
This study shows both feasibility and effects of a strength and endurance program during chemotherapy for lung cancer. The effects were significantly positive for the intervention group in every area (strength, endurance, QOL, independence). There were many issues with the study, however, making it difficult to apply to other populations. One huge issue is that it is unclear how many of the patients were SCLC versus NSCLC. These populations would have a wide difference in the natural history of disease on platinum regimen for the first few cycles; therefore, not knowing the content of each group is problematic. There were also large differences at baseline, so the effects are harder to evaluate. There was a very small sample size and large dropout rate. The intervention was feasible, but only given inpatient, so it is unclear if it is feasible for an outpatient population and these regimens are currently most typically administered outpatient in the United States. Although promising, it would need to be repeated to be generalizable.
Nurses should take away from this study that there is the possibility that endurance, strength, and QOL are improved by a program of strength and endurance training during chemotherapy. The results are not generalizable and would need further studies to confirm. There was no harm, but it cannot be recommended based solely on this study at this time.
Maeda, T., & Hayakawa, T. (2017). Dyspnea-alleviating and survival-prolonging effects of corticosteroids in patients with terminal cancer. Progress in Palliative Care, 25, 117–120.
To evaluate the effectiveness of corticosteroid to improve dyspnea and prolong survival in patients with terminal cancer
Retrospective chart review of 52 patients with terminal cancer who received corticosteroid for dyspnea. Effectiveness of corticosteroid to reduce dyspnea was assessed using the Support Team Assessment Schedule (STAS-J) and patients were classified as responders (n = 30) and non-responders (n = 22) based on STAS-J scores. Survival was compared between the groups, with patient survival being the primary endpoint.
Retrospective chart review of terminal patients who received either oral or IV corticosteroids. Patients were classified as responders or non-responders and survival was compared between the groups.
Effectiveness of corticosteroids to alleviate dyspnea was assessed using the Support Team Assessment Schedule (STAS-J) dividing patients into responders and non-responders. The Mann-Whitney U test compared survival between responders and non-responders, the chi-square test analyzed patient background information, and the Common Terminology Criteria for Adverse Events (CTCAE), version 4, evaluated adverse effects.
There was significant improvement in survival for patients who responded to corticosteroids with reduced dyspnea then those that did not using the Mann-Whitney U test (8.5 versus 5 days, p = 0.0019). Side effects observed with corticosteroids included insomnia (15.4%), delirium (11.5%), and hyperglycemia (3.8%).
The use of corticosteroid alone or in combination with opioid did reduce dyspnea in some patients at end of life and, therefore, resulted in prolonged survival. However, side effects of corticosteroids must be taken into consideration when assessing reduced dyspnea and evaluating the benefit of prolonged survival.
Dyspnea occurs at end of life and can be difficult to manage. Therapies to effectively reduce dyspnea at end of life are needed. Corticosteroid therapy may alleviate dyspnea in some patients at end of life. Nurses must continue to assess effectiveness of corticosteroids to reduce dyspnea along with side effects that may occur from therapy.
