且且: 評估骨盆固定器對於放射治療擺位誤差的影響。 姐姐盟主法: 本研究選擇三種骨盆部位的惡性腫瘤作為分析比較的對象: 包括了子宮頸瘖1 0 例, 攝護腺癌4 例, 及直觴癒2 例。在執行放射治療計畫之前即以隨機抽樣的方式區分為傳統未加骨 盆固定器與使用骨盆固定器兩組患者。開始治療後每周拍攝兩張照野片,照野片拍攝的方向是前 後或兩個l 面方向。;$:研究共取得34張模綴攝影片與1 4 9 張照野片。放射治療方式在兩組之間沒有 任何差異, 除直腸癌是以三ml野治療外其餘I句是四照野方式治療。記錄放射治療擺位誤差的方法 為比較模擬攝影X 光片與照野片的左右、頭閥、前後、以及旋轉等軸的誤差。分析擺位誤差的方 法是以ιtest (兩尾)及c h i呵ua re 方法分別評估誤差平均值及誤差超過5 mm比例等數值有無統計學上 的差異。 益星﹒ 傳統未加骨盆固定音量與使用骨盆固定器兩組之間的誤差型態並不相同。以誤差平均值方式 評估, 兩者左右( p~ 0.44 5) 、頭閥( p= 0 . 09 2 l 、與旋轉軸( p =0 . 3 3 7 1 均未有明顯差別。惟有機頭2 7 0 度 峙的前後軸達到統計差異( p =0 . 0 1 61 ;使用骨盆固定器患者的平均誤差(0 . 2 1 m m ' SD = l.llmm l 明顯 小於未使用骨盆固定器患者的平均誤差(l 日m m ' S D =2. 58 m m l 。以誤差超過5mm 比例的方法作評 估, 使用骨盆固定器可減少前後軸的誤差( p =O . 0 4 6l ' 但反而使頭腳軸的誤差加大( p ~O .

Purpose: To eva luate the extent of influence of setup deviation by pelvic immobilization device. Materials al/d Met /rods: Thi s prospective randomized study composed of two study group s that were with or without pelvic immobilization device. We included three kinds of malignant diseases that originated in pelvic cavi ty; these were 10 cases of cerv ical cancer, 4 cases of prostate cancer, and 2 cases of recta l cancer. Except from the two patients of rectal cancer, all of them were treated with four-field box techniq ue and the princip le of radiation technique was all the same in both groups. The porta l films were taken from anterior-posterior and bila tera l directions with the freque ncy of twice per week. There were 34 simulati on films and 149 porta l films to be eva luated. The setup error was recorded by comparison the iso-center shift between simulation and porta l films of four individual axes , that were latero-lateral. caudo-crania l, anterior-posterior axis and degree of rotation. The statistic methods for eva luation the results were two-tail t-test and chi-square methods for mean value of setup devia tion and ratio of iso-center shift exceeded 5-mm, respecti vely. Results: The patterns of setup error were different between non-immobili zation and immobilization groups. When eval uated by mean setup error, there were no significant differencer between the two groups of the laterolateral (p=0.4 45) and caudo-cranial (p=0.092) axes, the degree of rotatio n was also no di fference at all (p=0.337). In anterior-posterior axis eva luated by gantry 270 degree, the mean setup error of the immobi lizatio n group (0.2 1-mm, SD= 1.11mm) was significant smaller than non-immobilization grou p (1.54 -mm, SD=2 .58nun) (p=O.O16). Evaluation by the ratio of iso-center shift exceeded 5-mm, the immobi lized group showed significant reduction in the error of anterior-posterior axis (p=0.046), but this group had opposed behavior of the caudocranial axis (p=O.O 18). The latero-Iateral (p=0.359) and rotationa l (p=0.803) axes did not show any significant difference between the two groups. COl/elusion : With the immobilization device, there has significant improvement of the anterior-posterior axis, but the cando-c ranial axis has opposed effect when we eva luated by the ratio of setup error excee ded 5-mm. The iso-center shift in latero-Iateral axis has no significa nt difference despite of the used of this immobi lization device. So, we must pay more effort to avoid the inter-treatment varia tion of the cando-cranial axis when we use this kind of pelvic immobilization device.
