Radiotherapy   (translated from Japanese)
... 血液の供給が発達していない腫瘍では、低酸素状態、いわゆる低酸素症 ()、が発生し、放射線の作用に抵抗性が増大する。すなわち、低酸素では増殖の繰り返しが減少し、酸素がイオン化することで発生するフリーラジカルの産生も低下することで、作用が減弱する。 脳腫瘍では極めて高い用量では、生命維持に必要な正常な中枢神経に障害が及び神経細胞は再生しないことから中枢神経死を引き起こし、患者が死亡する恐れがある。 放射線療法は仕組みにより3つに大別される。 外部照射治療 (; XBRT) もしくは遠隔照射治療 (teletherapy) 近接照射治療 () 密封線源 () あるいは非密封線源放射線治療 () これらは、放射線源と標的との位置関係による分類で、外部照射は身体の外からの照射であり。密封線源あるいは非密封線源は身体の内部に放射性物質を入れ込む。近接照射治療の場合は挿入した密封線源を通常は治療後に摘出する。 出典 装置・作用原理 粒子線 ...
