Abstract
Objective
To investigate the correlation between skin elasticity and setup error in optical surface image-guided radiotherapy.
Methods
The skin elasticity (R7) data of the head, chest and abdomen were extracted and analyzed its correlation with age by systematic literature review. Fifty-four patients diagnosed with nasopharyngeal carcinoma, breast cancer and cervical cancer were recruited in this study. Firstly, the patients were positioned based on the room laser and markers. Subsequently, the patient position was verified by the Varian On-Board Imager, and then C-Rad Catalyst was adopted to obtain surface images in two states (mask or non-mask) as reference images. In the subsequent fraction treatment, after initial positioning, the local calibration was performed by Catalyst, and setup errors in three directions were recorded. Meanwhile, the patient setup was verified by CBCT twice a week. The Pearson correlation analysis was performed to analyze the correlation between setup error and age.
Results
The skin elasticity was negatively correlated with aging (P SI>AP.
Conclusion
In optical surface-guided radiotherapy of head and neck cancer, skin elasticity may be a significant index for assessing the setup errors in male patients.
Key words:
Skin elasticity; Surface image-guided radiotherapy; Set-up error
期刊介绍:
The Chinese Journal of Radiation Oncology is a national academic journal sponsored by the Chinese Medical Association. It was founded in 1992 and the title was written by Chen Minzhang, the former Minister of Health. Its predecessor was the Chinese Journal of Radiation Oncology, which was founded in 1987. The journal is an authoritative journal in the field of radiation oncology in my country. It focuses on clinical tumor radiotherapy, tumor radiation physics, tumor radiation biology, and thermal therapy. Its main readers are middle and senior clinical doctors and scientific researchers. It is now a monthly journal with a large 16-page format and 80 pages of text. For many years, it has adhered to the principle of combining theory with practice and combining improvement with popularization. It now has columns such as monographs, head and neck tumors (monographs), chest tumors (monographs), abdominal tumors (monographs), physics, technology, biology (monographs), reviews, and investigations and research.
