Fotonlarla yap\u0131lan geleneksel \u0131\u015f\u0131n terapisi ile kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda par\u00e7ac\u0131k terapisi, biti\u015fikteki sa\u011fl\u0131kl\u0131 dokunun \u0131\u015f\u0131ma maruziyetini azaltabiliyor ve t\u00fcm\u00f6r\u00fcn arkas\u0131ndaki dokunun tamamen korunmas\u0131n\u0131 sa\u011flayabiliyor. Bundan dolay\u0131 par\u00e7ac\u0131k terapisi beyin, omurilik, g\u00f6zler ve akci\u011fer gibi \u0131\u015f\u0131maya duyarl\u0131 organlar\u0131n yak\u0131n\u0131ndaki t\u00fcm\u00f6rler i\u00e7in ideal tedavidir. H\u0131zl\u0131 bir \u015fekilde b\u00fcy\u00fcyen doku \u0131\u015f\u0131maya kar\u015f\u0131 daha hassas tepki verdi\u011finden, proton terapisi \u00f6zellikle \u00e7ocuklardaki ve ergenlerdeki kanser hastal\u0131klar\u0131 i\u00e7in idealdir. Sa\u011fl\u0131kl\u0131 doku i\u00e7in doz en aza indirilerek hormon veya b\u00fcy\u00fcme bozukluklar\u0131 veya ikincil maligniteler gibi uzun d\u00f6nem riskler azalt\u0131labilir. Par\u00e7ac\u0131k terapisi, geleneksel \u0131\u015f\u0131n terapisi ile kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, tedavi verimlili\u011fi bak\u0131m\u0131ndan daha y\u00fcksek bir biyolojik etki sunuyor. Bu durum, \u00f6zellikle sarkomlar veya melanomlar gibi \u0131\u015f\u0131maya diren\u00e7li t\u00fcm\u00f6rlerin tedavisi i\u00e7in de ge\u00e7erlidir.<\/p>\n <\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n

Bu \u00f6zellikler, malzemeden ge\u00e7erken beraberinde \u00e7ok say\u0131da biyofiziksel avantajlar getirmektedir: T\u00fcm\u00f6r\u00fcn proksimalinde daha d\u00fc\u015f\u00fck bir giri\u015f dozu, t\u00fcm\u00f6r b\u00f6lgesinde neredeyse tam bir enerji depolamas\u0131 (“Bragg-Peak” olarak adland\u0131r\u0131lan duruma uygun olarak, bkz.

Karbon iyonlar\u0131yla yap\u0131lan terapinin \u00f6zellikleri<\/h2>\n

I\u015f\u0131n terapisinin t\u00fcm\u00f6r h\u00fccrelerini \u00f6ld\u00fcrmesi bak\u0131m\u0131ndan etkinli\u011fi \u0131\u015f\u0131n\u0131m\u0131n t\u00fcr\u00fcne g\u00f6re belirlenir. Kaliteleri do\u011frusal enerji transferinden (LET, \u0130ngilizcesi \u201cLinear Energy Transfer\u201d) \u00f6l\u00e7\u00fcl\u00fcr. Bu, \u0131\u015f\u0131n\u0131m taraf\u0131ndan ge\u00e7ilen maddenin iyonizasyon yo\u011funlu\u011funu belirtir. Malzemenin zay\u0131f iyonizasyonunu neden olan (Low-LET \u0131\u015f\u0131n\u0131m\u0131) fotonlarla kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, karbon iyonlar\u0131, \u00e7ok karma\u015f\u0131k t\u00fcm\u00f6r h\u00fccresi yaralanmalar\u0131ndan sorumlu olan (High-LET \u0131\u015f\u0131n\u0131m\u0131) uzunluk birimi ba\u015f\u0131na (High-LET \u0131\u015f\u0131n\u0131m\u0131) y\u00fcksek yo\u011funluklu iyonizasyon olaylar\u0131 \u00fcretirler (Res. 3). D\u00fc\u015f\u00fck LET \u0131\u015f\u0131n\u0131m\u0131, t\u00fcm\u00f6r h\u00fccrelerinin hayatta kalmas\u0131n\u0131 sa\u011flayan tipik olarak b\u00fcy\u00fck \u00f6l\u00e7\u00fcde onar\u0131labilir DNA hasar\u0131na neden olur. Y\u00fcksek LET \u0131\u015f\u0131n\u0131m\u0131 h\u00fccre \u00f6l\u00fcm\u00fcne neden olan \u00e7ok karma\u015f\u0131k, onar\u0131lamayan DNA hasarlar\u0131na neden olur. Bu etkili, onar\u0131lamayan DNA hasarlar\u0131 LOW-LET \u0131\u015f\u0131n\u0131m\u0131ndan sonra yakl. %20\u2019de ve High-LET \u0131\u015f\u0131n\u0131m\u0131ndan sonra yakl. %70\u2019dedir. Yani par\u00e7ac\u0131klar\u0131n g\u00f6receli biyolojik etkinli\u011fi (RBE, \u0130ngilizcesi \u201cRelative Biological Effectiveness\u201d) fotonlar\u0131nkinden daha y\u00fcksektir.<\/p>\n

Bunun anlam\u0131, protonlar\u0131n ve karbon iyonlar\u0131n ayn\u0131 \u0131\u015f\u0131n dozunda fotonlardan daha fazla t\u00fcm\u00f6r h\u00fccresi \u00f6ld\u00fcrmesidir. Bu \u00f6zellikle, RBE\u2019si fotonlarla kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda 3-4 kat daha y\u00fcksek olan karbon iyonlar i\u00e7in ge\u00e7erlidir. B\u00f6ylece karbon iyon terapisi, kemik ve yumu\u015fak doku sarkomlar\u0131, yava\u015f b\u00fcy\u00fcyen t\u00fcm\u00f6rler, geleneksel \u0131\u015f\u0131n terapisinden sonra lokal n\u00fcksler veya \u0131\u015f\u0131nlara kar\u015f\u0131 son derece diren\u00e7li hipoksik (d\u00fc\u015f\u00fck oksijenli) t\u00fcm\u00f6rler gibi geleneksel \u0131\u015f\u0131n terapisine diren\u00e7li t\u00fcm\u00f6rler i\u00e7in uygundur. \u00c7ok say\u0131da ara\u015ft\u0131rma, hem klinik \u00f6ncesi hem de klinik olarak, geleneksel \u0131\u015f\u0131n terapisine diren\u00e7li olan bu t\u00fcr t\u00fcm\u00f6rlerin \u00e7o\u011fu zaman karbon iyon ile ba\u015far\u0131l\u0131 bir \u015fekilde tedavi edilebildi\u011fini g\u00f6sterdi. Bu ger\u00e7ekler, kansere kar\u015f\u0131 olan m\u00fccadeleye yeni ve iyimser bir boyut katmaya yard\u0131m ediyor.<\/p>\n<\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n
