Abstract
Purpose
We investigated sleep parameters and patient-reported outcomes before, during, and after induction Bacillus Calmette-Guerin therapy using questionnaires and actigraphy in patients with non-muscle invasive bladder cancer.
Methods
We investigated 10 patients who received Bacillus Calmette-Guerin therapy once weekly for 8 weeks. The International Prostate Symptom Score, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30, Functional Assessment of Cancer Therapy-Bladder, and multi-item Short Form-8 tools were used to assess patient-reported outcomes. Participants completed all questionnaires before (baseline), at the 4th and 8th doses, and 1 month after the last Bacillus Calmette-Guerin dose. The MotionWatch8 was fastened to patients’ waist throughout the study. Composite sleep quality was determined based on sleep duration, efficiency, and fragmentation.
Results
We observed a transient increase in frequency/nocturia subscores and the insomnia subscore. The number of patients with poor sleep quality increased from 0 (0%) at baseline to 7 (70%) at the 4th dose and to 6 (60%) patients at the 8th dose. Among 10 patients, 6 (60%) were assigned to the sleep deterioration group and 4 (40%) to the non-deterioration group. Sleep quality was restored to baseline levels in 5 of 6 patients (83%) within 1 month after the last dose in the sleep deterioration group, and the nocturia subscore of the International Prostate Symptom Score was significantly increased only in this group (P=0.03).
Conclusions
This is the first study that confirms intravesical Bacillus Calmette-Guerin-induced sleep quality deterioration based on a questionnaire survey and actigraphy.
