Objective: The objective of this study was to investigate the frequency of acute and late toxicities, as well as changes in the quality of life (QOL) for breast cancer patients following radiotherapy (RT). Materials and Methods: A total of 108 breast cancer women were recruited for this prospective study. Data were collected at various intervals; prior to, and 1, 3, 6 months, and 1 year after radiation therapy. The primary outcomes were toxicity radiation therapy oncology group/European Organization for Research and Treatment of Cancer (EORTC) criteria. Our secondary outcome was QOL, measured using EORTC QLQ-C30 and Edmonton Symptom Assessment Scale. We employed Friedman's two-way analysis to evaluate the changes in QOL over the course of 1 year. Results: The early toxicities that are most commonly experienced include pharyngeal, skin, and mucous membrane toxicity. Late toxicities frequently involve skin and submucosal toxicity. To measure patient functionality, all functional subscale scores except for the patient's emotional state increased over time compared to pre-RT. Symptoms of the patients, which were included in the QOL symptom scale, decreased during the follow-up period, except for fatigue; however, changes in pain, insomnia, and loss of appetite did not significantly change. We identified the analogous symptom profiles in Edmonton. Although patients' overall health scores declined in the 1 st and 3 rd months after radiotherapy (RT), they rebounded at 6 and 12 months. Conclusion: For breast cancer patients, RT did not adversely affect functional capacity or exacerbate symptoms, but persistent fatigue did increase during the observation period. Health-care professionals ought to devise strategies to assist patients with skin toxicity and fatigue.

Purpose To evaluate the potential toxicity of operation microscopes with halogen and light emitting diode (LED) light source on the rabbit eyes. Materials and methods Thirty-two eyes of 16 male New Zealand pigmented rabbits were involved in the study. The rabbits were divided into two groups according to the type of light source applied. Only one eye of each rabbit was exposed to illumination light, unexposed fellow eyes served as the control group. Experimental groups included group 1 exposed to halogen light for 2 h and evaluated 1 day and 1 week after the illumination, group 2 exposed to LED light for two hours and evaluated 1 day and 1 week after the illumination. On the first and seventh days after exposing the light, we evaluated the rabbit corneas using in vivo confocal microscopy (IVCM). At the end of the seventh day, the Hematoxylin-eosin staining and TUNEL staining were performed to investigate the presence of apoptosis in the retina and retina pigment epithelium. Results Early IVCM findings revealed corneal epithelial cell ovalization and indistinct intercellular borders in the halogen light group. We also observed more increase in the keratocyte density index (23.7% vs 14.1%, p = 0.001, respectively) and the Bowman reflectivity index (12.4% vs 4.1%, p = 0.001, respectively) at first day of the light exposure in halogen light group compared to LED light group. However, late IVCM indicated that these findings disappeared one week later. No apoptosis was observed in the corneal and retinal layers in early and late examination groups. Conclusion The present experimental study demonstrated that both halogen and LED lights, which were commonly used for microscopic eye surgery, had no sustained adverse effect on the cornea and retina of the rabbits; however, halogen light had a temporary adverse effect on corneal epithelium and stroma, which resolved within 1 week.
