Background/Aim: Many patients with locally advanced cancer of the esophagus or esophagogastric junction receive definitive or neoadjuvant radio-chemotherapy. Patient anticipation of this treatment can cause or aggravate distress and sleep disorders. This study aimed to identify the prevalence of sleep disorders and risk factors. Patients and Methods: Thirty-eight patients assigned to radio-chemotherapy were retrospectively evaluated for pre-treatment sleep disorders. Investigated characteristics included age; sex; performance score; comorbidity index; previous malignancies; family history; distress score; emotional, physical or practical problems; tumor site; histology and grading; tumor stage; planned treatment; and relation to 2019 Coronavirus pandemic. Results: Sleep problems were reported by 15 patients (39.5%). Significant associations were found for higher distress scores (p=0.016) and greater numbers of emotional problems (p<0.0001). A trend was observed for greater numbers of physical problems (p=0.176). Conclusion: The prevalence of sleep problems

BACKGROUND/AIM: Many patients with malignant gliomas are scheduled for radiochemotherapy, which may cause emotional distress associated with sleep problems. This study aimed to determine the prevalence of such sleep problems in these patients and identify risk factors. PATIENTS AND METHODS: Fifty-seven patients scheduled for radiochemotherapy for grade II-IV gliomas were retrospectively investigated for pre-treatment sleep problems. Fifteen characteristics were evaluated including temporal relation to COVID-19 pandemic, age, gender, performance status, comorbidity, (family) history of malignancies, distress score, emotional problems, physical problems, practical problems, involved sites, glioma grade, upfront surgery, and corticosteroids. RESULTS: Nineteen patients stated pre-treatment sleep problems (prevalence=66.7%). Significant associations with sleep problems were found for female gender (p=0.023), presence of emotional problems (p=0.006), and ≥4 physical problems (p<0.001). A trend was found for distress scores ≥5 (p=0.077). CONCLUSION: The prevalence of sleep problems was high. Risk factors were determined that can be used to identify patients who likely benefit from psychological support.

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.

Background/Aim: Being scheduled for radiotherapy can cause emotional distress. This study aimed to identify risk factors in 338 patients assigned to radiotherapy for breast cancer. Patients and Methods: Nineteen potential risk factors including the COVID-19 pandemic were investigated for associations with the six emotional problems included in the National Comprehensive Cancer Network Distress Thermometer. Results: Worry and fears were significantly associated with age ≤60 years; sadness with age and Karnofsky performance score (KPS) <90; depression with KPS and Charlson Comorbidity Index ≥3; loss of interest with KPS. Trends were found for associations between sadness and additional breast cancer/DCIS, Charlson Index and chemotherapy; between depression and additional breast cancer/DCIS, treatment volume and nodal stage N1-3; between nervousness and additional breast cancer/DCIS, mastectomy and triplenegativity; between loss of interest and Charlson Index, family history of breast cancer/DCIS, invasive cancer, chemotherapy, and treatment volume. The COVID-19 pandemic did not increase emotional problems. Conclusion: Several risk factors for emotional problems were identified. Patients with such factors should receive psychological support well before radiotherapy.

Background/Aim: A considerable number of patients with lung cancer are scheduled for definitive or adjuvant radiotherapy. Prevalence and potential risk factors of preradiotherapy sleep disturbances were evaluated. Patients and Methods: Nineteen factors were retrospectively investigated for associations with pre-radiotherapy sleep disturbances in 77 lung cancer patients. Factors included COVID-19 pandemic; age; gender; performance score; comorbidity index; history of another malignancy; distress score; number of emotional, physical or practical problems; patient's request for psychological support; histology; tumor stage; upfront surgery; chemotherapy; and type of radiotherapy. Results: Thirty-one patients (40.3%) reported sleep disturbances that were significantly associated with distress score 6-10 (p=0.019), ≥2 emotional problems (p=0.001), ≥5 physical problems (p<0.001), and request for psychological support (p=0.006). Trends were found for female gender (p=0.064) and stereotactic body radiation therapy (p=0.057). Conclusion: Many lung cancer patients assigned to radiotherapy reported sleep disturbances. Risk factors can be used to identify patients in need of psychological support already before treatment.

Background/Aim: Many patients with prostate cancer receive definitive or adjuvant radiotherapy. This study aimed to identify the frequency of sleep disturbances and corresponding risk factors prior to radiation treatment. Patients and Methods: Data of 48 patients assigned to local or loco-regional irradiation for prostate cancer were retrospectively analyzed for pre-radiotherapy sleep disturbances. Fifteen characteristics were analyzed including age, performance status, comorbidity, history of previous malignancy, distress score, (emotional, physical or practical) problems, prostate-specific antigen, primary tumor stage, Gleason-score, upfront androgen deprivation therapy (ADT), treatment volume, brachytherapy, and COVID-19 pandemic. Results: Pre-radiotherapy sleep disturbances were reported by 20.8% of patients and significantly associated with distress scores ≥4 (p<0.0001) and ≥3 physical problems (p=0.0001). Trends were found for Karnofsky performance score ≤80 (p=0.095), Gleason score 7b-9 (p=0.079), and ADT (p=0.067). Conclusion: Pre-radiotherapy sleep disturbances were less common in prostate cancer patients than in other cancer patients. Risk factors were identified that can help identify patients requiring psychological support prior to radiotherapy.

Background/Aim: Radiotherapy and radiochemotherapy are common treatments for rectal and anal cancer.Anticipation of treatment may cause distress and sleep disorders.This study aimed to identify risk factors for sleep disorders.Patients and Methods: In 42 patients with rectal or anal cancer scheduled for radiotherapy, 16 characteristics were analyzed for associations with pre-radiotherapy sleep disorders including age, gender, performance score, comorbidity, patient's or family history of additional cancer/melanoma, distress score, emotional/physical/practical problems, tumor site and stage, surgery and relation to COVID-19 pandemic.Results: Overall prevalence of pre-radiotherapy sleep disorders was 42.9%.Sleep disorders were significantly associated with Karnofsky performance score 60-80 (p=0.044), Charlson comorbidity index ≥3 (p=0.0012), distress score 6-10 (p=0.00012), and more emotional (p=0.0012), physical (p=0.0004) or practical (p=0.033) problems.A trend was found for female gender (p=0.061).Conclusion: Sleep disorders were common in patients with rectal or anal cancer scheduled for radiotherapy.Risk factors can help identify patients requiring psychooncological support already prior to the start of radiotherapy.

Background/Aim: Many patients with gynecological malignancies receive postoperative radiotherapy, which can lead to fear and sleep disorders. We aimed to identify the prevalence of and risk factors for sleep disorders. Patients and Methods: Sixty-two patients assigned to radiotherapy for gynecological malignancies were retrospectively evaluated. Seventeen characteristics were analyzed for associations with pre-radiotherapy sleep disorders including age, Karnofsky performance score, Charlson comorbidity index, history of additional malignancy, family history of gynecological cancer, distress score, emotional, physical or practical problems, tumor site/stage; chemotherapy, treatment volume, brachytherapy, and the COVID-19 pandemic. Results: The prevalence of preradiotherapy sleep disorders was 46.8%. Sleep disorders were significantly associated with Charlson comorbidity index ≥3 (p=0.012), greater number of physical problems (p<0.0001), and advanced primary tumor stage (p=0.005). A trend was found for greater number of emotional problems (p=0.075). Conclusion: Pre-radiotherapy sleep disorders are common in patients with gynecological malignancies, particularly in those with specific risk factors. Patients should be offered early psychological support.

Background/Aim: Many patients with head-and-neck cancer are scheduled for irradiation. This study was performed to determine the frequency of and risk factors for pre-radiotherapy sleep disturbances in these patients. Patients and Methods: A total of 103 patients with head-and-neck cancer scheduled for radiotherapy were included in this retrospective study. Eighteen characteristics were evaluated including timing of start of radiotherapy relative to COVID-19 pandemic; age; gender; Karnofsky performance score; Charlson comorbidity index; history of another malignancy; family history of malignancy; distress score; number of emotional, physical or practical problems; request for psychological support; tumor site and stage; upfront surgery; planned chemotherapy; and brachytherapy boost. Results: The frequency of pre-radiotherapy sleep disturbances was 42.7%. This was significantly associated with age ≤63 years (p=0.049), Karnofsky performance score ≤80 (p=0.002), Charlson comorbidity index ≥3 (p=0.005), history of another malignancy (p=0.012), emotional (p=0.001) or physical (p<0.001) problems, and request for psychological support (p=0.002). Conclusion: Sleep disturbances were frequent in patients assigned to radiotherapy of head-and-neck cancer. Recognizing risk factors for sleep disturbance helps identify patients requiring psychological support.
