Unyango lweProton

Unyango lweProton luhlobo lwemitha esetyenziselwa ukunyanga umhlaza. Njengezinye iintlobo zemitha, unyango lweproton lubulala iiseli zomhlaza kwaye luyekise ukukhula.

Ngokungafaniyo nezinye iintlobo zonyango lwe-radiation ezisebenzisa i-x-reyi ukutshabalalisa iiseli zomhlaza, unyango lweproton lusebenzisa umqadi wamasuntswana akhethekileyo abizwa ngokuba ziiproton. Oogqirha banokujolisa ngcono kwimiphunga yeproton kwi-tumor, ke akukho monakalo mncinci kwizicubu ezisempilweni. Oku kuvumela oogqirha ukuba basebenzise idosi ephezulu yemitha ngonyango lweproton kunokuba banokusebenzisa ii-ray-x.

Unyango lweProton lusetyenziselwa ukunyanga umhlaza ongasasazwanga. Ngenxa yokuba ibangela umonakalo omncinci kwizicubu ezisempilweni, unyango lweproton luhlala lusetyenziselwa umhlaza osondele kakhulu kumalungu abalulekileyo omzimba.

Oogqirha banokusebenzisa unyango lweproton ukunyanga ezi ntlobo zomhlaza zilandelayo:

• Ubuchopho (i-acoustic neuroma, amathumba engqondo ebuntwaneni)
• Iliso (i-ocular melanoma, retinoblastoma)
• Intloko nentamo
• Imiphunga
• Umqolo (chordoma, chondrosarcoma)
• Indlala
• Inkqubo yesifo somhlaza

Abaphandi bafunda nokuba unyango lweproton lungasetyenziselwa ukunyanga ezinye iimeko ezingenabungozi, kubandakanya ukonakala kwe-macular.

INGABA ISEBENZA KANJANI

Umboneleli wakho wezempilo uya kukulingana ngesixhobo esikhethekileyo esigcina umzimba wakho ngexesha lonyango. Esona sixhobo sisetyenzisiweyo sixhomekeke kwindawo onomhlaza kuyo. Umzekelo, abantu abanomhlaza weentloko banokulungela imaski ekhethekileyo.

Okulandelayo, uya kuba nekhompyuter yecomputer (CT) okanye imaging resonance imaging (MRI) ukuskena imephu yendawo ngqo ekufuneka inyangwe. Ngexesha lokuskena, uya kunxiba isixhobo esikunceda ukuba uhlale ungangqalanga. I-oncologist ye-radiation iya kusebenzisa ikhompyuter ukulandelela ithumba kunye nokucacisa ii-angles apho iiproteon zingena khona emzimbeni wakho.

Unyango lweProton lwenziwa ngokunyanga ngaphandle. Unyango luthatha imizuzu embalwa ngosuku kwisithuba seeveki ezi-6 ukuya kwezi-7, kuxhomekeka kuhlobo lomhlaza. Ngaphambi kokuba unyango luqale, uya kungena kwisixhobo esiya kukubamba. Ingcali yonyango ngemitha iya kuthatha ii-x-reyi ezimbalwa ukuze zilungelelanise unyango.

Uya kubekwa ngaphakathi kwesixhobo esimilise njenge-gantry. Iya kujikeleza ijonge kuwe kwaye yalathe iiproton kwicala lesifo. Umatshini obizwa ngokuba yi-synchrotron okanye i-cyclotron uyila kwaye ukhawulezise iiproton. Emva koko iiprothoni ziyasuswa kumatshini kunye noomazibuthe zibahambisa ngqo kwi-tumor.

Ingcali iya kulishiya igumbi ngelixa usenonyango lweproton. Unyango kufuneka luthathe kuphela imizuzu emi-1 ukuya kwezi-2. Akufanele uziva ungonwabanga. Emva kokuba unyango luphelile, igcisa liza kubuyela egumbini kwaye likuncede ususe isixhobo esikugcinileyo.

IMIPHUMELA

Unyango lweProton lunokuba neziphumo ebezingalindelekanga, kodwa ezi zihlala zithambile kunokuba zinemitha ye-x-ray kuba unyango lweproton lubangela umonakalo omncinci kwizicubu ezisempilweni. Iziphumo ebezingalindelekanga zixhomekeke kummandla onyangoweyo, kodwa zinokubandakanya ukuba bomvu kwesikhumba kunye nelahleko yeenwele okwexeshana kwindawo yemitha.

EMVA KWENKQUBO

Ukulandela unyango lweproton, kuya kufuneka ukwazi ukuqhubeka nemisebenzi yakho yesiqhelo. Uya kubona ugqirha wakho rhoqo kwiinyanga ezi-3 ukuya kwezi-4 kuvavanyo olulandelayo.
