且且:在不同分期之鼻咽癌比較強度調控順形治療(IMR T) 治療計畫與順形治療計畫之差異 材料與台注: 我們以三個不同分期的鼻咽癌病人, 其電腦治療計畫除使用強度調控順形治療(IMRT) 技術外、也使用三度空間順形治療技術及傳統兩側相對照野技術。我們利用不同的技術組台運用於起初治療範圍及加強治療範圍, 其重點在於劑量曲線分布( d os e c onfo rmal ity ) 、體積劑量長條圖( d os e - v o lume histogram, DVH ) 及劑量對較敏感正常組織的影響。 益是: 以強度調控順形治療技術完成之計畫其劑量曲糗分布較能貼近腫瘤體積, 為了達到保護肥腺和眼睛等器官的目的, 必須於放射治療一開始即採用強度調控順形治療技術。採用強度調控順形治療技術能給予腫瘤更高治療劑量, 也造成眼球器官的傷害高於篩竇接近眼窩處位置。所給予放射治療劑量及劑量曲線分佈將會影響日後眼球組織的部分功能。 結論: 不同分期的腫瘤及凹面形狀的腫瘤, 採用強度調控順形治療技術對肥腺部分將增加些許好處。但無論如何,使用強度調控順形治療技術採共面方式完成之治療計畫在治療位於中央部位組織:例如上篩竇區域( u pp e r ethmoid sinus area ) 時導致對眼球部分結構傷害。
Purpose : To compare intensity-modulated radiotherapy (IMRT) treatment plans with conventional treatment plans for different stage of nasopharyngeal carcinoma Materials and Methods : We used 3 cases of different T stage of nasopharyngeal cancer using IMRT techniques, as well as three-dimensional conformal radiotherapy technique (3D-CRT), and traditional bil-opposing fields technique. We use different combinations of techniques in initial and boost fields. These plans were compared with respect to dose conformality, dose-volume histogram (DVH) and dose to the sensitive normal tissue structures. Results : The planned dose distributions were more conformal to the tumor target volume by IMRT in T1 and T3 tumor but not in T4 lesion with extending to eye balls level. To achieve the parotid and ear organs preservation purpose, IMRT should be done from the beginning of radiotherapy. The IMRT technique may deliver more radiation dose to eye balls for the lesion over the ethmoid sinus nearing the orbit level. The radiation dosage and conformality will be lost after the limitation of the eye structure. Conclusion : The IMRT will gain the benefit of parotid sparing in different stage of tumor and the concave shape tumor. However, the IMRT with co-planar treatment planning may cause some harm to eye structures for the lesion at the central location such as upper ethmoid sinus area
