Sleep disturbances are prevalent in cancer patients, especially those with advanced disease. There are few published intervention studies that address sleep issues in advanced cancer patients during the course of treatment. This study assesses the impact of a multidisciplinary quality of life (QOL) intervention on subjective sleep difficulties in patients with advanced cancer.

This randomized trial investigated the comparative effects of a multidisciplinary QOL intervention (n = 54) vs. standard care (n = 63) on sleep quality in patients with advanced cancer receiving radiation therapy as a secondary endpoint. The intervention group attended six intervention sessions, while the standard care group received informational material only. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS), administered at baseline and weeks 4 (post-intervention), 27, and 52.

The intervention group had a statistically significant improvement in the PSQI total score and two components of sleep quality and daytime dysfunction than the control group at week 4. At week 27, although both groups showed improvements in sleep measures from baseline, there were no statistically significant differences between groups in any of the PSQI total and component scores, or ESS. At week 52, the intervention group used less sleep medication than control patients compared to baseline (p = 0.04) and had a lower ESS score (7.6 vs. 9.3, p = 0.03).

A multidisciplinary intervention to improve QOL can also improve sleep quality of advanced cancer patients undergoing radiation therapy. Those patients who completed the intervention also reported the use of less sleep medication.

Patients experience reductions in quality of life (QOL) while receiving cancer treatment and several approaches have been proposed to address QOL issues. In this project, the QOL differences between older adult (age 65+) and younger adult (age 18–64) advanced cancer patients in response to a multidisciplinary intervention designed to improve QOL were examined.

This study was registered on ClinicalTrials.gov, NCT01360814. Newly diagnosed advanced cancer patients undergoing radiation therapy were randomized to active QOL intervention or control groups. Those in the intervention group received six multidisciplinary 90-minute sessions designed to address the five major domains of QOL. Outcomes measured at baseline and weeks 4, 27, and 52 included QOL (Linear Analogue Self-Assessment (LASA), Functional Assessment of Cancer Therapy–General (FACT-G)) and mood (Profile of Mood States (POMS)). Kruskall–Wallis methodology was used to compare scores between older and younger adult patients randomized to the intervention.

Of 131 patients in the larger randomized controlled study, we report data on 54 evaluable patients (16 older adults and 38 younger adults) randomized to the intervention. Older adult patients reported better overall QOL (LASA 74.4 vs. 62.9, p = 0.040), higher social well-being (FACT-G 91.1 vs. 83.3, p = 0.045), and fewer problems with anger (POMS anger–hostility 95.0 vs. 86.4, p = 0.028). Long-term benefits for older patients were seen in the anger–hostility scale at week 27 (92.2 vs. 84.2, p = 0.027) and week 52 (96.3 vs. 85.9, p = 0.005).

Older adult patients who received a multidisciplinary intervention to improve QOL while undergoing advanced cancer treatments benefited differently in some QOL domains, compared to younger adult patients. Future studies can provide further insight on how to tailor QOL interventions for these age groups.
