Light Therapy and Occupational Therapy Fatigue Management-Based Intervention for Patients With Genitourinary Cancers

December 22, 2025 updated by: City of Hope Medical Center

Assessing Efficacy of a Light Therapy and Occupational Therapy Fatigue Management-Based Intervention for Patients With Genitourinary Cancers

This clinical trial evaluates light therapy and occupational therapy in improving cancer related fatigue (CRF) patients with genitourinary cancers. Light therapy is a non-pharmacological and evidence-based intervention for managing fatigue in cancer patients. The use of light therapy can provide a low burden, inexpensive, and easy to disseminate intervention approach that can potentially have a larger impact on CRF. In addition, occupational therapy is a standard, but often underutilized, component of the multi-disciplinary approach to cancer care. Using the combination of light therapy and occupational therapy may be effective in CRF management.

Study Overview

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate patient's fatigue at post-intervention (3 months from baseline).

SECONDARY OBJECTIVE:

I. To evaluate whether the change (improvement) in fatigue as measured by the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue tool, from pre-interventions to post interventions is significantly different between intervention groups in patients with genitourinary cancers.

THIRD OBJECTIVE:

I. To assess patient perceived changes in occupational performance as measured by the Canadian Occupational and Performance Measure (COPM) tool, in the occupational therapy (OT) group, compared to the control group in patients with genitourinary cancers.

OUTLINE: Patients are randomized to 1 of 4 arms.

ARM I (Bright white light [BWL]): Patients self-administer 30 minutes of light delivered via light glasses every morning for 3 months. Patients attend 6 follow up sessions to address any questions regarding the wearable light therapy glasses.

ARM II (OT): Patients undergo 6 occupational therapist-led sessions over 60 minutes each.

ARM III (BWL and OT): Patients self-administer 30 minutes of light delivered via light glasses every morning for 3 months. Patients attend 6 follow up sessions to address any questions regarding the wearable light therapy glasses and to complete the occupational therapist-led session over 60 minutes.

ARM IV (CONTROL): Patients undergo routine treatment and usual follow up care with their medical oncologist.

After completion of study, patients are follow-up for 3 months.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Functional Assessment of Cancer Therapy - (FACIT)
Time Frame: At baseline
The effects of light therapy and occupational therapy (OT) on FACIT will be evaluated by comparing light therapy to no-light therapy and comparing occupational therapy to no-occupational therapy. Analysis of variance test will be used for the factorial comparisons, with a two-sided statistical significance level (alpha = 0.05). The interaction between occupational therapy and light therapy will be explored (to understand whether the effect of light therapy [if any] on FACIT would change with occupational therapy and vice versa). The Functional Assessment of Chronic Illness Therapy (FACIT- fatigue scale) is a 13-item patient-reported measure of fatigue. Items are scored on a 0 - 4 response scale with anchors ranging from "Not at all" to "Very much so". To score the FACIT-fatigue, all items are summed to create a single fatigue score with a range from 0 to 52. The higher the score, the better the Quality of Life (QoL).

Self-reported occupational performance - Baseline
Time Frame: Baseline
Will determine if an OT-based intervention can improve self-reported occupational performance from preassessment to immediately after time point 2 (session 6) This outcome measure is Canadian Occupational Performance Measure (COPM). Its administration involves four steps: (a) the patient is asked to identify occupations that are difficult for him or her in self-care, productivity and leisure; (b) the importance of these problem occupations is rated on a scale of 1-10 in terms of importance (1 = least important, 10 = most important); (c) patients' perceptions of performance and satisfaction with their five most important problems are rated on two separate 10-point scales (performance 1 = not able to do it, 10 = able to do it extremely well; satisfaction 1 = not satisfied at all, 10 = extremely satisfied) and finally (d) at reassessment both the performance and satisfaction ratings are repeated (and the change between assessment and reassessment is evaluated).
