快活光子刀在肝門靜脈癌治療? - 抗癌

※ 引述《nextsolar (林至強)》之銘言：
: 家人的肝癌合併肝門靜脈阻塞
: 請問只有快活光子刀(Rapid Arc)放射治療可以把肝門靜脈阻塞打通嗎
: 像另一種自費的放射治療 "螺旋刀" 也可以嗎?
: 或是 "螺旋刀" 跟 "快活光子刀" 其實是一樣的
: 或是, 哪一種比較好呢(對於肝門靜脈阻塞)
: 另外, 目前中部有快活光子刀的醫院只有澄清嗎?

well - please pardon my english reply.

these are modelities of radiotherapy.
螺旋刀 is helical IMRT (intensity-modulated radiotherapy)
--> these deliver doses of radiotherapy slice-by-slice.

快活光子刀 is rapidarc which is a relatively new kind of
IMRT called IMAT (intensity-modulated arc therapy)
the principal benefit of it is due to better focus of radiotherapy
into the targets and spares the healthy tissue better.

rapid arc is new technology - it results in less damage to healthy
tissue - whether it translate into survival benefit, that you
will need to consult your surgeon/oncologist.
