Umdlavuza wamaphaphu kanye nokwelashwa kwe-proton
Amaphaphu aseduze nezinye zezitho nezicubu ezizwela kakhulu nezibalulekile, okuhlanganisa inhliziyo, umminzo, nomgogodla. Cishe amaphesenti angama-20 kuphela amathumba emaphashini angelashwa ngokuhlinzwa; ezinye iziguli ngokuvamile zidinga umthamo omkhulu we-radiotherapy noma i-radiotherapy ehlanganiswe nezinye izindlela zokwelapha.
Ukwelashwa okuqondiswe yi-Proton kwamathumba amaphaphu kusho ukuthi iziguli zinethuba elikhulu lokululama, imisebe engaphansi kwezicubu ezizungezile, kanye nemiphumela engemihle embalwa kune-X-ray radiotherapy.
Izinzuzo zokwelapha i-proton yomdlavuza wamaphaphu
Ngomqondo, ukwelashwa kweproton umdlavuza wamaphaphu uzo:
1. Target only to the isisu
2. Vikela izicubu zamaphaphu ezinempilo
3. Vikela inhliziyo yesiguli, umphimbo nomgogodla
4. Gcina izinga lempilo ngesikhathi sokwelashwa
5. Yehlisa imiphumela emibi yokwelashwa
Kunzima kakhulu ukwelapha izimila zamaphaphu ngeradiotherapy yendabuko ngoba:
Imisebe ye-radiotherapy evamile ithinta izicubu ezinempilo ezizungeze izimbobo zamaphaphu zesilonda, okuhlanganisa izicubu zamaphaphu ezinempilo, inhliziyo, umphimbo, nezicubu zomgogodla. Lezi zakhiwo zizwela kakhulu emisebeni, ngisho nangemithamo ephansi yemisebe, ukucekelwa phansi kwalezi zicubu kuzodala imiphumela emibi kakhulu futhi kubeke engozini izinga lempilo yesiguli.

· If the cancer recurs after radiotherapy, the options for treatment will be very limited. Using X-ray radiotherapy to repeatedly treat the same area and the vicinity of the cancer is very difficult and may have a very high risk. The radiation dose needed to effectively treat the tumor may have a very large toxicity to the surrounding healthy tissue, but the low dose is not enough to kill the cancer cells.
Kunoma yikuphi ukwelashwa nge-radiotherapy yomdlavuza, kwezinye izimo izehlakalo zezinkinga ezingase zibe zimbi kakhulu zingaba phezulu kakhulu. Lokhu kwenza isinqumo sokunikeza iziguli ukwelashwa kwe-radiotherapy yendabuko kube nzima kakhulu:
1. Umthamo wemisebe esimila ungaphansi komthamo ofanele (lokhu kunciphisa ithuba lokukhululwa kwesifo); noma
2. Umthamo wemisebe ofanele wamathumba kanye nemisebe eyingozi enkulu yezicubu ezinempilo.
izinhlobo umdlavuza wamaphaphu that proton therapy can treat
Izinhlobo zomdlavuza ezingahlinzekwa ngokwelashwa kwe-proton okuthuthukile kwesifuba namaphaphu zifaka:

Izinzuzo zokwelashwa kwe-proton yomdlavuza wamaphaphu
I-Proton therapy iwuhlobo olunembe kakhulu lwe-radiotherapy oluqondise izimila zamaphaphu ezindaweni ezibucayi. Ngoba imishayo ye-proton ingalawulwa ngokucophelela, ama-proton angagcina amandla awo aphezulu futhi athinte ngqo isimila, futhi ukuvezwa kwemisebe ezicutshini ezibucayi ezinempilo nezicubu ezizungeze amaphaphu kungancishiswa. Ukwelashwa kweProton kunezinzuzo ezithile ezigulini ezinokungasebenzi kahle kwamaphaphu nesifo senhliziyo.
Proton therapy – Studies have shown that proton therapy is as effective as X-ray in the treatment of umdlavuza wamaphaphu weselula ongewona omncane, and can significantly reduce side effects, such as lung inflammation and esophageal inflammation. Studies have shown that some patients with lung cancer receive larger doses of proton radiation, but have fewer side effects.
Ukwehliswa kwemisebe ezicutshini ezizungezile. I-Intensity-modulated proton therapy (IMPT) noma ukuskena kwe-pencil beam, okusanda kwethulwa e-Scripps Proton Therapy Center eCalifornia, i-intensity-modulated proton therapy (IMPT) noma ukuskena kwe-pencil beam kuvumela odokotela ukuthi basebenzise i-proton therapy yomthamo omkhulu ezigulini ' izimila. Ngesikhathi esifanayo nciphisa umthamo wemisebe ezithweni ezibalulekile ezizungeze isiguli.
Ukwelashwa okuhlosiwe okwengeziwe kungenziwa ngokuskena uthango lwepeni. Uma kuqhathaniswa nokwelashwa kwe-proton okujwayelekile okujwayelekile, i-Scripps Proton Therapy Center's intensity-adjustable pen-beam scanning technology (IMPT) ingalapha izimila eziyinkimbinkimbi, yenze ukusatshalaliswa kwemithamo eminingi ngaphakathi kwesimila futhi yehlise umthamo wemisebe ezicutshini ezizungezile. Umthamo wemisebe okhishwa ukuskena kohlaka lwepeni ungadlulela ngale kwesimila esiqondiwe, ngakho-ke uma kuqhathaniswa nokwelashwa kwe-proton esakazwayo kanye nokwelashwa kwe-X-ray (IMRT), isilinganiso esincane semithamo siyadingeka.
Ingozi yemiphumela emibi iyancipha kakhulu. Ucwaningo lukhombisile ukuthi imithamo ephezulu ye-proton radiotherapy ingafinyelela izimila zamaphaphu, kanti ingozi ye-esophagitis nenyumoniya inciphile kakhulu.
Ukunciphisa ukuchayeka emisebeni ezicutshini ezivamile zamaphaphu nomnkantsha. Ucwaningo lukhombisile ukuthi ukwelashwa kwe-proton kunganciphisa ukuvezwa kwezicubu ezijwayelekile zamaphaphu nomnkantsha emisebeni uma kuqhathaniswa nokwelashwa kwendabuko kwe-quantum (X-ray). Ukunciphisa imisebe emnkantsheni wethambo nakho kunganciphisa ukukhathala okuhlobene nokwelashwa.
Yehlisa ingozi yomdlavuza wesibili. Ucwaningo oluningi luye lwabonisa ukuthi indawo ezungeze iziguli ezithola ukwelashwa ngemisebe ye-X-ray izoba nezinga eliphezulu kakhulu lomdlavuza wesibili. Ngoba ukwelashwa kwe-proton kunganciphisa kakhulu umdlavuza wamaphaphu, kumthamo ojwayelekile wemisebe yezicubu, ucwaningo lubikezela ukuthi ubungozi bomdlavuza wesibili buphansi.
Ukwelashwa kwe-Proton kuphephe kakhudlwana kumdlavuza wamaphaphu ophinde wabuya
Ngoba ukwelashwa kwe-proton kungagxilisa kangcono umthamo wayo wemisebe kulokho okuhlosiwe, ukuze ingadubuli kwenye indawo, ifaneleka kakhulu ezindaweni ezithole imisebe ye-X-ray ngaphambi kokwelashwa. Indawo efakwe imisebe ngaphambi kokwelashwa inselele kakhulu futhi iyingozi kunoma yikuphi ukwelashwa nge-radiotherapy. Izicubu ezizungezile zamathumba avelayo azikwazi "ukukhohlwa" umthamo wangaphambilini wemisebe. Noma yimiphi imithamo eyengeziwe iyaqhubeka nokwandisa ingozi yokulimala kwezicubu ezivamile. Ngokunciphisa umthamo wemisebe ezicutshini ezalashwa ngaphambilini, ukwelashwa kwe-proton kungasiza ekunciphiseni (kodwa hhayi ukuqeda) ezinye zezingozi ezihlobene nokushiswa kabusha kwemisebe.
Ibiza malini i-proton therapy?
Izindleko zokwelashwa kwe-Proton zincike esimweni sesiguli, ubude besikhathi sokwelashwa kanye nesikhungo sokwelapha. Izindleko zokwelashwa kwe-proton zingabiza noma yikuphi phakathi kokungu-$4,00,000-500,000 USD e-USA kanye no-$30,000 – 60,000 USD e-India.
Ungaya kuphi ukuthola i-proton therapy?
I-Proton therapy iyatholakala e-USA, Germany, India, China naseJapan njengamanje. Iziguli zingavakashela noma yisiphi salezi zikhungo zokwelapha i-proton.
Itholakala kuphi i-proton therapy eNdiya?
I-Proton therapy iyatholakala e-Chennai eNdiya.
