Ukwelashwa kwe-Proton

Ukwelashwa kweProton uhlobo lwemisebe esetshenziselwa ukwelapha umdlavuza. Njengezinye izinhlobo zemisebe, ukwelashwa kweproton kubulala amangqamuzana omdlavuza futhi kuwayekise ukukhula.

Ngokungafani nezinye izinhlobo zokwelashwa ngemisebe ezisebenzisa ama-x-ray ukubhubhisa amangqamuzana omdlavuza, i-proton therapy isebenzisa umsebe wezinhlayiya ezikhethekile ezibizwa ngama-proton. Odokotela bangabhekisa kangcono imishayo ye-proton phezu kwesimila, ngakho-ke kukhona ukulimala okuncane ezicubu zomzimba ezinempilo. Lokhu kuvumela odokotela ukuthi basebenzise umthamo ophakeme wemisebe ngemithi yokwelashwa kweproton kunalokho abangakusebenzisa ngama-x-ray.

Ukwelashwa kweProton kusetshenziselwa ukwelapha umdlavuza ongakasakazeki. Ngoba kubangela ukulimala okuncane kwizicubu ezinempilo, ukwelashwa kwe-proton kuvame ukusetshenziselwa umdlavuza osondele kakhulu ezingxenyeni ezibucayi zomzimba.

Odokotela bangasebenzisa i-proton therapy ukwelapha lezi zinhlobo zomdlavuza ezilandelayo:

• Ubuchopho (i-acoustic neuroma, izicubu zobuchopho ebuntwaneni)
• Iso (i-ocular melanoma, i-retinoblastoma)
• Ikhanda nentamo
• Amaphaphu
• Umgogodla (chordoma, chondrosarcoma)
• Indlala yesinye
• Umdlavuza wesistimu yeLymph

Abaphenyi bafunda nokuthi ngabe ukwelashwa kwe-proton kungasetshenziswa yini ukwelapha ezinye izimo ezinganomdlavuza, kufaka phakathi ukonakala kwe-macular.

INDLELA ESEBENZA NGAYO

Umhlinzeki wakho wokunakekelwa kwezempilo uzokulingana nedivayisi ekhethekile egcina umzimba wakho umile ngesikhathi sokwelashwa. Idivayisi yangempela esetshenzisiwe incike lapho unomdlavuza khona. Isibonelo, abantu abanomdlavuza wekhanda bangafakwa imaski ekhethekile.

Okulandelayo, uzoba neskena se-computed tomography (CT) noma se-magnetic resonance imaging (MRI) ukukhomba indawo ngqo okufanele ilashwe. Ngesikhathi sokuskena, uzogqoka idivayisi ekusiza ukuthi uhlale unganyakazi. I-oncologist yemisebe izosebenzisa ikhompyutha ukulandelela isimila futhi ichaze ama-engeli lapho imishayo ye-proton izongena khona emzimbeni wakho.

Ukwelashwa kwe-Proton kwenziwa ngokugula okungalalisiwe. Ukwelashwa kuthatha imizuzu embalwa ngosuku esikhathini esingamasonto ayisithupha kuye kwayisikhombisa, kuya ngohlobo lomdlavuza. Ngaphambi kokuba ukwelashwa kuqale, uzongena kudivayisi ezokubamba unganyakazi. I-radiation Therapist izothatha ama-x-ray ambalwa ukulungisa kahle ukwelashwa.

Uzobekwa ngaphakathi kwedivayisi emise okwedonki ebizwa nge-gantry. Izophenduka izungeze wena futhi ikhombe ama-proton lapho ibheke khona isimila. Umshini obizwa ngokuthi i-synchrotron noma i-cyclotron udala futhi usheshise ama-proton. Ngemuva kwalokho ama-proton ayasuswa emshinini bese odonsa bawaqondisa esihlahleni.

Uchwepheshe uzophuma egumbini ngenkathi uthola ukwelashwa kwe-proton. Ukwelashwa kufanele kuthathe kuphela umzuzu owodwa kuya kwemibili. Akufanele uzwe ukungakhululeki. Ngemuva kokuphela kokwelashwa, uchwepheshe uzobuyela egumbini futhi akusize ususe idivayisi ebikubambile unganyakazi.

OKUQHAMUKA UMA UDLA IMISHANGUZO

Ukwelashwa kwe-Proton kungaba nemiphumela engemihle, kepha lokhu kuvame ukuba mnene kakhulu kunemisebe ye-x-ray ngoba ukwelashwa kwe-proton kubangela ukulimala okuncane kwizicubu ezinempilo. Imiphumela emibi incike endaweni elashwa, kepha ingafaka ukubomvu kwesikhumba kanye nokulahleka kwezinwele okwesikhashana endaweni yemisebe.

NGEMVA KWENQUBO

Ukulandela ukwelashwa kwe-proton, kufanele ukwazi ukuqala kabusha imisebenzi yakho ejwayelekile. Cishe uzobona udokotela wakho njalo ezinyangeni ezi-3 kuya kwezi-4 zokuhlolwa kokulandela.
