Evaluation of Sleep Disturbances in Patients With Bladder Cancer Scheduled for Local or Loco-regional Radiochemotherapy.

ABSTRACT

BACKGROUND/AIM: Organ-sparing treatment is increasingly used for bladder cancer, particularly for patients with significant comorbidities or advanced age. The upcoming treatment can cause distress and sleep disturbances. This study investigated pre-radiotherapy sleep disturbances in these patients. PATIENTS AND METHODS: Twenty-two patients with bladder cancer scheduled for local or loco-regional radiotherapy were retrospectively evaluated. Sixteen characteristics were analyzed for sleep disturbances including age, sex, performance score, comorbidities, previous malignancy, distress score, emotional problems, physical problems, treatment situation, treatment intent, current primary tumor and nodal stage, distant metastasis, treatment volume, concurrent chemotherapy, and Coronavirus Disease 2019 pandemic. RESULTS: Eleven patients (50.0%) reported sleep disturbances that were significantly associated with distress scores ≥5 (p=0.035). Trends were found for age ≤75 years (p=0.183), ≥2 emotional problems (p=0.183), ≥5 physical problems (p=0.064), and distant metastasis (p=0.090). CONCLUSION: Half of the patients reported pre-radiotherapy sleep disturbances. Risk factors facilitate identification of patients requiring psychological support.
