中文摘要 | 在放射治療過程中,患者的擺位誤差(set-up errors)是影響精確治療的關鍵因素,越是精確的放射治療,對照射部位準確性要求越高。本研究主要利用錐狀射束電腦斷層(cone-beam computed tomography,CBCT)評估具有侵入管路的頭頸部患者在放射治療中定位的準確性,共收集72位接受影像導引放射治療(image-guided radiotherapy,IGRT)的患者位移資料進行分析。其中我們將患者分成四組,7位A組患者所測得左右、頭腳及前後三軸系統偏差的平均位移及標準差分別為1.92±0.10 mm、1.68±0.06 mm、2.11±0.09mm,隨機偏差分別為2.04±0.25 mm、0.88±0.02 mm、1.04±0.05 mm。12位B組患者所測得所測得左右、頭腳及前後三軸系統偏差的平均位移及標準差分別為2.17±0.13 mm、1.70±0.06 mm、1.30±0.03 mm,隨機偏差分別為1.02±0.03 mm、0.93±0.03 mm、0.80±0.02 mm。27位C組患者所測得所測得左右、頭腳及前後三軸系統偏差的平均位移及標準差分別為1.92±0.10 mm、1.61±0.10 mm、1.63±0.10 mm,隨機偏差分別為0.89±0.03 mm、0.84±0.04 mm、0.76±0.04 mm。26位D組患者所測得所測得左右、頭腳及前後三軸系統偏差的平均位移及標準差分別為1.13±0.04 mm、1.30±0.06 mm、1.92±0.10 mm,隨機偏差分別為0.61±0.02 mm、0.67±0.02 mm、0.65±0.03 mm。利用單因子變異數分析法(One-Way ANOVA)分析結果,我們發現在系統偏差中,在左右及前後方向上(p =0.003及0.008)均具有統計學上的顯著差異(p < 0.05)。而隨機偏差則只有在左右上(p =0.001)具有統計學上的顯著差異(p < 0.05)。最後,我們希望利用回溯性的研究成果來作為臨床治療時的參考,並提供較佳的治療定位準確性,有效的改進及提升放射治療品質。 |
英文摘要 | In the process of radiation therapy, the set-up error is the key factor affect the precision. Higher treatment accuracy is required for more precise radiation therapy. This study was designed to evaluate the positioning accuracy of the head and neck patients with invasive tubes which use cone-beam computed tomography (CBCT) in radiation therapy. We collected seventy-two patients received image-guided radiotherapy (IGRT) to analyze the setup data. The seventy-two patients were divided into four groups in this study. In the Group A of seven patients: The mean translation and standard deviation of systematic errors in X(L-R), Y(S-I), Z(A-P) were 1.92±0.10 mm, 1.68±0.06 mm, and 2.11±0.09 mm. And that of random errors were 2.04±0.25 mm, 0.88±0.02 mm, and 1.04±0.05 mm, respectively. In the Group B of twelve patients: The mean translation and standard deviation of systematic errors in X(L-R), Y(S-I), Z(A-P) were 2.17±0.13 mm, 1.70±0.06 mm, and 1.30±0.03 mm. And that of random errors were 1.02±0.03 mm, 0.93±0.03 mm, and 0.80±0.02 mm, respectively. In the Group C of twenty-seven patients: The mean translation and standard deviation of systematic errors in X(L-R), Y(S-I), Z(A-P) were 1.92±0.10 mm, 1.61±0.10 mm, and 1.63±0.10 mm. And that of random errors were 0.89±0.03 mm, 0.84±0.04 mm, and 0.76±0.04 mm, respectively. In the Group D of twenty-six patients: The mean translation and standard deviation of systematic errors in X(L-R), Y(S-I), Z(A-P) were 1.13±0.04 mm, 1.30±0.06 mm, and 1.92±0.10 mm. And that of random errors were 0.61±0.02 mm, 0.67±0.02 mm, and 0.65±0.03 mm, respectively. Using One-way ANOVA analysis of the systematic errors, we found the statistically significant difference (p<0.05) in X (L-R) and Z (A-P) direction(p = 0.003 and 0.008). And that of the statistically significant difference (p <0.05) of random errors only in X (L-R) direction (p = 0.001). Finally, we hope to use the retrospective study which result can be a clinical treatment reference, and provide better accuracy in treatment positioning, effectively improve and enhance the quality of radiotherapy. |
