Cannici, J., Malcolm, R., & Peek, L. A. (1983). Treatment of insomnia in cancer patients using muscle relaxation training. Journal of Behavioral Therapy and Experimental Psychiatry, 14, 251–256.
The intervention consisted of individual muscle relaxation training over three sessions plus instructions for home practice twice daily. Patients were either in the relaxation (n = 15) or usual care (n = 15) group. The outcome was sleep.
Patients were undergoing the active treatment and long-term follow-up phases of care.
The study was a randomized, controlled trial.
Daily diary and questionnaire pertaining to sleep behavior the previous night, for a total of nine nights
Sleep-onset latency was reduced in the relaxation group compared with the usual care group; differences in sleep latency were maintained at the three-month follow-up. No differences were found in other sleep variables.
No cost issues existed.

To compare the effectiveness of two psychotropic medications, mirtazapine and imipramine, on distressing somatic symptoms (i.e., pain, nausea, vomiting, decreased appetite, and sleep disturbance) of cancer as well as symptoms of depression and anxiety.
Patients self-selected to receive psychotropic medication and supportive psychotherapy (intervention group) or supportive psychotherapy only. Those who elected to take medication were randomly enrolled to receive mirtazapine or imipramine. Mean dosage of mirtazapine ranged from 5 to 30 mg/day, depending on the visit. Mean dosage of imipramine ranged from 5 to 100 mg/day, depending on the visit. Each group was then assessed at three visits: baseline and three and six weeks after therapy had begun.
Patients were undergoing the active treatment phase of care.
The study used a prospective, repeated measures design.
Mirtazapine is effective in resolving insomnia and in reducing the symptoms of anxiety and depression in patients with cancer who have depression, anxiety, or adjustment disorders.
Mirtazapine may be useful in treating anxiety, depression, and insomnia in patients undergoing chemotherapy for cancer who have clinically relevant anxiety or depression. More systematic research, such as placebo-controlled studies, is required.

To evaluate the efficacy of oral branched-chain amino acids versus placebo on anorexia and food intake in patients with cancer
A mixture of 4.8 g branched-chain amino acids was administered three times daily versus placebo powder three times daily for 60 minutes before each meal for seven consecutive days.
Multiple institutions in Italy that were not listed or further described
A double-blinded, placebo-controlled, randomized trial design was used.
Nutritional status was within normal limits for both groups prior to and at the end of study. Daily caloric intake was significantly increased in the treatment arm. There was no change in the placebo group. Incidence of anorexia was significantly decreased in the treatment arm (100% prior to and 45% at the end of study). There was no significant change in the placebo arm (100% prior to and 84% at the end of study). Blood tests showed a significant increase in plasma amino acid levels and a decrease in free tryptophan levels in the treatment arm and no change in levels noted in the placebo arm.

Studies were excluded if they reported on healthy volunteers, drug misuse–related constipation, or bowel obstruction.
A total of 186 references were retrieved. If citation screening did not identify whether a study was eligible, the full text was reviewed for acceptability. Two authors independently screened studies and discussed differences of opinion. Randomized controlled clinical trials were evaluated for inclusion.
Well-designed clinical trials are needed to help identify which laxatives are most effective for palliative care patients with constipation.
Very few clinical trials effectively evaluated the use of laxatives in this patient population.

Initial searching provided 100 clinical trials and 71 review articles. A final group of seven trials was identified for consideration in this review.
The seven final studies encompassed data on 594 patients.
The review highlights the necessity of considering what treatment children will accept in managing symptoms.
This review was done in children with functional constipation, so findings may not be clearly applicable in children with constipation related to cancer treatment. PEG may be helpful and more effective than lactulose in the management of constipation in children with cancer, and may be more accepted than milk of magnesia.

PHASE OF CARE: End-of-life care
APPLICATIONS: Palliative care
No difference in effectiveness was demonstrated in lactulose compared with senna; senna plus lactulose compared with magnesium hydroxide plus liquid paraffin; misrakasneham compared with senna; and docusate plus senna compared with placebo plus senna.
The best laxatives for this patient population is unclear.
Very few clinical trials effectively evaluated the use of laxatives in this patient population.
More RCTs are needed to help evaluate the effectiveness and improve the quality of care of patients in palliative care.

STUDY PURPOSE: To assess the effects of support interventions on the psychological and physical health of informal caregivers of patients in the terminal stage of disease
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: End-of-life care
APPLICATIONS: Palliative care
Nine studies used interventions aimed to directly support the caregiver, and in five of these, the intervention was also aimed at the patient. In two trials, the aim was to indirectly support the caregiver via patient support. A meta-analysis of eight studies aimed at direct caregiver support to reduce psychological distress, in favor of the intervention (SMD = –0.15, 95% confidence interval [–0.28, –0.02], p = 0.02). Studies measuring improvement in coping or quality of life did not show any significant effect of the intervention. Two trials showed improved access to health services with the intervention, and one did not show any difference between groups in physical health outcomes of the caregivers.
Support interventions aimed directly at the caregiver reduced short-term psychological distress, with a small effect size, and resulted in marginal and insignificant improvements in coping and quality of life.
Supportive interventions provided directly to informal caregivers had small but significant positive effects on caregiver psychological outcomes.
Can, G., Topuz, E., Derin, D., Durna, Z., & Aydiner, A. (2009). Effect of kefir on the quality of life of patients being treated for colorectal cancer. Oncology Nursing Forum, 36, E335-E342.
To determine the effectiveness of kefir in preventing treatment-related gastrointestinal complaints and to determine the effects of kefir on quality of life (QOL) among patients receiving chemotherapy treatment for colorectal cancer.
Patients were included if they had stage II, III, or IV colorectal cancer; were 18 years or older; had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2; and were receiving standard treatment with 5 FU or oral fluoropyrimidine. Patients were randomized to either the control group or the experimental (kefir) group. Kefir (500 mL) was industrially prepared by Altinkilic Company in Istanbul. Patients were instructed to use 250 mL of kefir two times per day for one week during chemotherapy treatment. Side effects of treatment were evaluated in both groups one week after each chemotherapy cycle. QOL was evaluated after the third and sixth cycles of treatment.
Patients were undergoing the active treatment phase of care.
The study was a randomized, controlled trial.
There were no statistically significant differences between groups in patients’ disease-related complaints before the intervention. No statistically significant changes were observed between pre- or posttreatment for the control group for the MSAS-GDI subscale scores; however, statistically significant increases in symptom distress (p < 0.05) were observed in the experimental (kefir) group from pre- to posttreatment. For the MSAS-PHYS subscale, the control group experienced a significant increase in symptoms over pretreatment scores (p < 0.05); however, a significant increase occurred in physical symptoms after each treatment cycle (p < 0.05) in the experimental group, with physical scores significantly higher (p = 0.03) in the experimental group after the fifth cycle compared to the control group. Scores for the MSAS-PSYCH were also significantly higher (p = 0.01) in the experimental group compared to the control group after the sixth treatment cycle. Total MSAS scores were significantly higher for each treatment cycle compared to pretreatment for the experimental group (p < 0.05) and were significantly higher than the control group after the fifth treatment cycle (p = 0.02). The experimental group reported significantly fewer problems sleeping than the control group after all rounds of chemotherapy (p = 0.05). No significant differences were observed between groups for QOL (p > 0.05).
The kefir intervention did not affect QOL. Patients receiving kefir reported increased physical and psychological systems and increased symptom distress compared to patients not receiving kefir but reported fewer problems sleeping.
Kefir may increase physical complaints, including gastrointestinal complaints, in patients with colorectal cancer receiving chemotherapy. Kefir does not have a significant effect on QOL. Further study is needed to determine the effects of kefir on sleep problems in this population.
Can, G., Erol, O., Aydiner, A., & Topuz, E. (2011). Non-pharmacological interventions used by cancer patients during chemotherapy in Turkey. European Journal of Oncology Nursing, 15, 178-184.
To determine the kind of nonpharmacological interventions used by Turkish patients with cancer for symptom management during chemotherapy, whether a relationship exists between symptom experience and nonpharmacological intervention use, and what personal and illness-related variables predict the symptom experience and nonpharmacological interventions use in this population
Patients completed the following. If patients were unable to complete the tools themselves, a friend or relative verbally asked the patient the questions.
The study was conducted at a single site, outpatient setting at the Istanbul University Institute of Oncology in Turkey.
Patients were undergoing the active phase of treatment care.
This was a descriptive study.
Most patients with cancer in Turkey preferred pharmacologic interventions for symptom management. Exercise, as a recognized evidence-based intervention, was only reported to be used by a few patients. The authors recommended that oncology nurses teach patients more about the side effects of chemotherapy and associated nonpharmacological interventions. Although other studies have produced such evidence-based recommendations, they were not developed from this study of self-reported symptoms and interventions of Turkish people receiving chemotherapy. The authors did not report if or how teaching occurred from the perspective of the nurse or the patient or family.
An individualized assessment of each patient's knowledge and preferences is important to all cultures and practices.

A double-blind, randomized phase II study to evaluate the safety and efficacy of acetyl-L-carnitine in the prevention of sagopilone-induced peripheral neuropathy. Oncologist, 18, 1190–1191.
To investigate if the addition of acetyl-L-carnitine (ALC) to sagopilone (SAG) in patients with ovarian cancer (OC) and castration-resistant prostate cancer (CRPC) reduced the overall incidence of SAG-induced peripheral neuropathy (PN) compared to SAG and placebo, and to evaluate the safety and efficacy of ALC-SAG compared to SAG-placebo
Patients were randomized to treatment and placebo-controlled arms. All patients received a three-hour infusion every three weeks of SAG 16 mg/m2 either with oral ALC (1000 mg) three times a day or oral placebo three times a day for six treatment cycles. ALC or placebo was continued for 30–33 days after the last SAG treatment. Patients with CRPC received oral prednisone 5 mg every two days as standard of care for quality of life.
Phase-II, prospective, placebo-controlled, double-blind, randomized trial
No difference in the incidence or median duration of PN existed in either arm. No difference existed in best overall response, tumor markers, time-to-event variables (progression free survival or time to progression), or discontinuations because of adverse events in either arm. Slightly more serious adverse events and grade 3–4 adverse events were reported in the SAG-placebo arm. ALC reduced the incidence of grade 3–4 PN in patients in the SAG-ALC arm compared to patients in the the SAG-placebo arm; however, actual statistical results were not reported.
ALC given concurrently with SAG in patients with advanced OC was reported to reduce the incidence of grade 3–4 PN after six cycles of treatment; however, no results showing statistical significance were provided.
ALC concurrently with SAG after six cycles reduced the incidence of grade 3–4 PN in patients with advanced OC. No benefit was observed in patients with CRPC or in reducing the incidence of grade 1–2 for either patients with OC or CRPC. Further randomized, controlled trials are needed to determine the benefits, duration of benefits, and quality of life for ALC-SAG or other neurotoxic regimens in diverse tumor types.
