摘要

三度空間順形放射治療是近年來以遠隔照射腫瘤的一種新技術，其方法是在不同角度照射時，照野可順著腫瘤形狀而改變。其目的是可提高腫瘤的照射劑量，減少正常組織所接受的照射。隨著電子技術的進步，電腦治療計劃的不斷更新，多葉式準直儀的發展，醫療影像的解晰度不斷提高。因此，放射腫瘤科同仁追求的先進順形治療技術，得以實現；對癌症局部控制的成功率得以提升，而照射引起的副作用相對地減少。本文重點是介紹順形放射治療的技術及其需要注意的條件，治療選擇的對象，更回顧近年國外治療的結果，做一整理性報導。

3-dimensional conformal radiotherapy is a new technique for cancer treatment by using external radiation fields. The multi-field approach is made to conform radiation dose closely to the tumor shape. The dose escalation for the tumors is the main purpose, and the normal tissue dose can relatively be reduced. With the currently advance electronic technology, the improvement of computer planning system, the development of multileaf collimator and the high resolution of the oncologic images, they achieve the dream of conformal technique for radiation oncologists. Furthermore, the local tumor control rate becomes better and the complication rate of normal tissues reduced or at least the same as conventional treatments. This report was to introduce the technical aspects and the indications of patient selection for conformal radiotherapy. The treatment results of recent years had been reviewed.
