Ukwelashwa ngemisebe ye-stereotactic yomzimba
I-stereotactic body radiation therapy (SBRT), eyaziwa nangokuthi i-stereotactic ablative radiotherapy (SABR). Selokhu yaqala ukusetshenziswa maphakathi nawo-1990, i-SBRT isizigqamisile ekwelapheni okukhulu kwezimila eziningi ngenxa yezinga layo eliphezulu lokulawula isimila, ukubekezelela kahle izicubu ezivamile, isikhathi eside sokusinda kanye neziguli ezilungele kakhulu. Umdlavuza wamaphaphu wasekuqaleni usuphenduke umzuzi walobu buchwepheshe. I-SBRT iwukwelashwa okusebenzayo kwesigaba esiphansi okungahlanyisi okungenziwa emtholampilo weziguli ezingalaliswa. Ngokuvamile iphathwa izikhathi ezingu-1-5, kanye ngosuku noma zonke izinsuku.
Uhlelo lwe-EDGE radiosurgery olusetshenziswa i-Henry Ford Hospital e-United States isizukulwane se-SBRT. Iyona esezingeni eliphezulu kakhulu engahlaseli isisu ukusula ubuchwepheshe kuze kube manje. Inganciphisa isikhathi sokwelashwa nge-radiotherapy umdlavuza wamaphaphu kuya kumaminithi angu-10-15, futhi konke ukwelashwa kuqedwa ngezinsuku ezingu-5. . Iziguli eziningi zingabuyela empilweni evamile ngokushesha ngemva kokwelashwa.
I-SBRT yomdlavuza wamaphaphu ongakwazi ukususwa ngokuhlinzwa
I-RTOG 0236 isifundo sokuqala somtholampilo esinezikhungo eziningi eNyakatho Melika ukwelapha i-SBRT ngenxa yokungasebenzi kahle komtholampilo. umdlavuza wamaphaphu. Ucwaningo lwezokwelapha lwe-RTOG 0236 lwaqala ngo-2004 futhi lwelapha iziguli ezingama-57 sezizonke. Ngo-2006, iziguli zabhaliswa. Imiphumela yomtholampilo mihle impela: izinga lokulawula isimila esiyinhloko leminyaka emi-3 lifinyelela ku-98%, kanti izinga lokusinda lingu-56%.
Ukusebenzisa i-SBRT kumdlavuza wamaphaphu okhishwe ngokuhlinzwa
Imiphumela yokwelapha ye-SBRT yomdlavuza wamaphaphu ongasebenzi ibonisa ukuthi ingaqeda ngempumelelo isimila esiyinhloko, futhi ukubekezelelana nakho kungcono kule ngxenye yabantu abasengozini enkulu. Ngenxa yalokhu, ithuba lokusetshenziswa kwalo ezigulini ezinomdlavuza wamaphaphu osebenzayo selithole ukunakwa. Imiphumela yomtholampilo ibonisa ukuthi inqobo nje uma umthamo wemisebe ophusile unikezwa, ukwelashwa kwe-SBRT kungathola umphumela wokwelapha osondelene kakhulu nalowo wokuhlinzwa kabusha noma i-lobectomy.
Ummese wangaphambili we-Speed ubuchwepheshe bokwelashwa be-SBRT obuphambili kakhulu kuze kube manje
Uhlelo lwe-EDGE lwe-tumor nonvasive radiosurgery luwuhlelo lokwelapha umdlavuza olwagunyazwa yi-US FDA ngo-2014. Luwuhlelo olusebenza kahle kakhulu lokuhlinza ngesimila. Kunzima ukwenza ukuhlinzwa okujwayelekile kumathumba afana namathumba ekhanda, umdlavuza wamaphaphu, namathumba omgogodla. , Umdlavuza wesibindi kanye nezinye izimila eziqinile zinemiphumela yokwelapha okunzima ukuyifinyelela ngokuhlinzwa okuvamile kanye nemishini yokwelapha nge-radiotherapy, futhi kuyisinqumo esingcono kakhulu seziguli ezinomdlavuza ukususa izilonda zesimila kuze kube manje.
Kusukela ngo-April 2014, uhlelo lokuqala lomhlaba lwe-EDGE lwe-radiotherapy olungavayisi isimila belusebenza kulo lonke uhlelo lwe-Henry Ford Hospital e-United States. Selaphe iziguli ezingaphezu kwama-400 zesimila, futhi izinga lokwaneliseka kokwelashwa (i-Tumor Co ntrol Rate) likhulu kunama-95%. Futhi akukho ukusabela okubi okwenzekayo. Kulezi ziguli zesimila, izimila ebuchosheni (kuhlanganise nezimila zobuchopho eziyisisekelo kanye ne-metastatic) zibalwe ku-31%, umdlavuza wamaphaphu ubalwe ku-29%, izimila zomgogodla zibalelwa ku-23%, izimila emathunjini ibalwa ku-9%, kanti umdlavuza we-adrenal ubalelwa ku-7%.
