Patients received either donepezil or placebo (5 mg) orally every morning for seven days. A research nurse contacted patients by daily telephone calls to assess symptoms and treatment toxicity. Patients were evaluated at the clinic on day 8. Patients returned for a final assessment on day 15, and those who chose to continue taking donepezil were provided with a two-week supply of the drug. Fatigue outcomes were assessed at baseline, day 8, and day 15.
The donepezil intervention did not show any improvement in fatigue in comparison to the placebo, as no significant difference was seen between groups at baseline and on day 8 for FACIT-F fatigue intensity scores.

Donepezil 5 mg every morning for seven days
Fatigue significantly was improved following a seven-day course of treatment with donepezil. Significant improvement was noted in anxiety, well-being, sleep problems, depression, and anorexia. Pain level was unchanged. Of the initial 27 patients enrolled in the study, 7 patients were discontinued from the study due to cellulitis (1 patient), concern about a possible drug-drug interaction (1 patient), transient arterial hypertension (1 patient), increasing muscle cramps (1 patient), and mild to moderate nausea (3 patients).

Methylphenidate and/or a nursing telephone intervention for fatigue in patients with advanced cancer: A randomized, placebo-controlled, phase II trial. Journal of Clinical Oncology, 31(19), 2421–2427.
Compare the effects of methylphenidate (MP) (psychostimulant) with those of a placebo (PL) on cancer-related fatigue. The effect of a combined intervention including MP plus a nursing telephone intervention (NTI) also was assessed.
Patients with a fatigue score of greater than or equal to 4 out of 10 on the Edmonton Symptom Assessment Scale (ESAS) randomly were assigned to one of the following four groups: MP plus NTI, PL plus NTI, MP plus control telephone intervention (CTI), and PL plus CTI.
Randomized, controlled trial; placebo controlled
The groups MP alone, NTI alone, or MP plus NTI proved not significantly better than PL for cancer-related fatigue. Anxiety improved with the telephone intervention (p = .01), as did sleep (p < .001).
MP, used alone or in combination with NTI, was not superior to the control group or the PL for fatigue or depression. NTI was associated with improvement in anxiety and sleep.
Although the use of MP did not prove to be effective for cancer-related fatigue, several cancer-related symptoms significantly were improved with NTI. Further research in this area would be ideal, but NTIs remain potentially effective for patient support and education and can have a positive effect on patient experience.

The objective of the study is to determine the effectiveness of oxygen versus air to decrease dyspnea and fatigue and to increase distance walked during a six-minute walk test.
Oxygen or air was delivered via nasal cannula during a six-minute walk test.
The study reported on a sample of 33 patients.
The study had the following inclusion criteria.
Patients were excluded if they were on oxygen therapy.
Double-blind, randomized, controlled crossover study
Fatigue and dyspnea were evaluated by a visual analog scale (0 = absence of symptoms and 10 = worst possible symptoms). Respiratory rate and heart rate were monitored. The outcomes measured were dyspnea at three and six minutes, fatigue at six minutes, and distance walked. This was repeated when patients received the crossover treatment. Patients and researchers both rated dyspnea. Oxygen saturation was measured at baseline before the crossover and at completion of the study.
No significant differences were noted between the two groups observed. Dyspnea score at three minutes, dyspnea score at six minutes, fatigue score at six minutes, and distance in feet walked at six minutes were not statically significant (p > 0.52). The authors concluded that the routine use of supplemental oxygen for dyspnea during exercise in this patient population cannot be recommended.

The objective of the study is to assess oxygen therapy in patients with cancer.
Patients received two courses of oxygen at 5 L per minute and two courses of room air at 5 L per minute. Patients were randomized to either air or oxygen and then crossed over to the other treatment.
The study reported on a sample of 14 patients with hypoxemic dyspnea caused by advanced cancer previously treated with supplemental oxygen. Patients had normal cognitive function (MMSE score of at least 24/30) and hypoxemia (oxygen saturation less than 90% when patients breathed room air for more than five minutes). All were receiving oxygen via nasal cannula at 4 L per minute.
The study was a prospective, crossover, double-blind trial.
A baseline assessment occurred after 30 minutes of bed rest and a minimum of 5 minutes of stable oxygen saturation on room air. Dyspnea was assessed with VAS (0 = none to 100 = most). RR was measured for one minute twice; the results were averaged and assigned a score of 1–4 for RR. Patients made blind choices as to which treatment was most beneficial. Pulse oximetry evaluations also were recorded.
Oxygen saturation, respiratory rate and effort, and VAS were significantly better on oxygen (p < 0.0001). Researchers concluded that oxygen is beneficial to patients with hypoxia and dyspnea at rest.

To compare subcutaneous (SC) injection versus nebulized morphine (median dose of 45 mg, equal to half of the scheduled equivalent opioid dose) on two separate days; because nebulized morphine is thought to have rapid onset of action and low systemic absorption, adverse effects may be avoided.
The study used a double-blind, randomized crossover trial design.
Significant improvement occurred in dyspnea scores from baseline to 60 minutes measured at 15-minute intervals for both SC (dyspnea score decreased from 5 to 3; p = 0.025) and nebulized morphine (dyspnea score decreased from 4 to 2; p = 0.007). No significant difference was found between SC and nebulized morphine for each time period. Bronchospasm was not observed in the nebulized treatment group.
Both routes were effective in this sample. The number of patients was insufficient to determine a difference between the routes.

The objective of this study was to assess the effect of one dose of subcutaneous (SC) morphine on dyspnea in patients with terminal cancer.
Patients were given 2.5 times their regular dose of morphine, administered at the time of their scheduled analgesic dose. In five patients who were not receiving opioids, the dose was 5 mg of morphine. The average dose administered was 22–28 mg.
The study reported on a sample of 20 consecutive patients with terminal cancer; all patients had severe dyspnea at rest because of restrictive respiratory failure.
The study was conducted on a palliative care unit.
The study was an open, uncontrolled trial.
The study had a small sample size.

This study was conducted to assess the effects of methylphenidate (MPH) on neuropsychological functions for patients with cancer on continuous subcutaneous (SQ) infusion of narcotics for pain.
Participants were assessed immediately before and two hours after dose for two days.
The study took place at Edmonton General Hospital in Alberta, Canada.
The study was a randomized, double-blind, placebo-controlled, crossover trial.
Significant improvement was noted in drowsiness, confusion, tapping speed, arithmetic skills, reverse digits, and visual memory (p < 0.001). Patients and investigators blindly chose MPH as more effective over the placebo in 13 of 14 cases.
In patients with cancer who had significant pain, immediate improvements in alertness, attention, and memory were noted.

Patients received 100 mg of thalidomide by mouth at night for 10 days. If improvement was shown, patients could continue.
This was an open-label study.
More than 30% improvement in symptom intensity was observed in the following parameters: difficulty falling asleep (17/35 = 49%), morning restedness (23/36 = 64%), insomnia (22/32 = 69%), nausea (16/36 = 44%), appetite (22/35 = 63%), and well-being (18/34 = 53%). Twenty-seven patients completed food intake forms on days 1 and 10. Caloric intake increased from 1,325 to 1,531 calories per day (p = 0.047). Three patients discontinued thalidomide because of adverse effects: dizziness (1) and drowsiness (2).
Findings need to be confirmed in double-blind studies.

To evaluate the efficacy of 1,000 mg fish oil capsules versus placebo of 1,000 mg olive oil capsules in a two-arm trial
A daily dose of 18 capsules was given over a two-week period. Dosage decreased to a minimum of six capsules daily secondary to intolerance. Mean eicosapentaenoic acid (EPA) dose was 1.8 g/day. Docosahexaenoic acid dose was 1.2 g/day.
The two-site trial was conducted in the Acute Palliative Care Unit at Grey Nuns Hospital and the inpatient and outpatient areas at Cross Cancer Institute in Edmonton, Alberta, Canada.
A randomized, placebo-controlled, double-blinded trial design was used.
Five patients in each group left the study secondary to gastrointestinal intolerance. There was no significant difference in any of the subjective or objective parameters between the two groups. Both groups showed an equal trend toward improved appetite, –9.8 for the fish oil and –9.0 for the olive oil placebo on the VAS.
