頭頸癌患者於放射治療中佩戴外科口罩之可行性

目的：新型冠狀病毒疫情期間，使用外科口罩對於頭頸癌的病患在接受放射治療中位置的準確性。方法：收集32位由2021年1月至8月頭頸癌病患使用S-type固定模具進行放射治療，治療時佩戴外科口罩型號為一般醫用外科口罩（未滅菌），規格為17.5cm × 9.15cm，並從影像導引定位系統（X-Ray Volume Imaging; XVI）得出擺位誤差影像之位移數據，最後用獨立t檢定分析對有否用外科口罩於各軸向擺位誤差是否有差異性存在。結果：21位沒有使用外科口罩的病患的平均位移為0.8±0.7mm、1.2±1.0mm、0.8±0.8mm，代表x，y，z方向，而11位的病患使用外科口罩的平均位移為0.8±0.8mm、1.8±1.0mm、1.3±1.1mm代表x，y，z方向，兩者實質上並無統計上的差異（p值＞0.05）。結論：頭頸癌病患使用S-type固定並在疫情期間佩戴外科口罩進行放射治療是可行的，既能保護醫療同仁的安全及不造成病患治療準確性之差異。

Objective: During the COVID-19 epidemic, the purpose of this study was to investigate the effect and feasibility of treatment position accuray with surgical masks in head and neck cancer patients. Methods: A total 32 patients set-up error data with S-type immobilization decive were collected by using X-Ray Volume Imaging system with registered images and then the t-test was analyzed by set-up error data whether it was statistically significant difference. Results: The set-up error of 21 patients without surgical masks were 0.8±0.7mm,1.2±1.0mm, 0.8±0.8mm, x, y, and z translational directions ,respectively, while the set-up error of 11 patients with surgical masks were 0.8±0.8mm, 1.8±1.0mm, 1.3± 1.1mm, x, y, and z translational directions, respectively, there were insignificant difference between the two groups (p value>0.05). Conclusions: Head and neck cancer patients with surgical mask are feasibility by using S-type immobilization decive during radiation therapy, it is suggested that protected staffs for the departments as well as the accuracy treatment position for the patients.
