The purpose of this study was to evaluate the feasibility and safety of night-time radiation therapy for physically independent patients. Methods: This retrospective study consisted of 100 consecutive patients with various types of malignancies treated by helical tomotherapy at night (6:00 PM or later). The safety and feasibility of nighttime radiation therapy were evaluated. Results: Among the 100 patients, 20 (20%) developed mild (Grade 1) or moderate (Grade 2) radiationinduced side effects during the treatment. No patient developed severe (Grade 3) or life-threatening (Grade 4) adverse events during, immediately after, or three months after radiation therapy. There were no physical or mental disadvantages caused by night-time radiation therapy. Conclusion: Night-time radiation therapy is feasible and acceptable for physically independent patients.}
