Kunzima ukuchaza uloyiko kunye nexhala olivayo xa ufumanisa ukuba wena okanye umntu omthandayo unomhlaza. Kwaye ke xa usiva ngonyango, unokoyika ngakumbi xa usiva "ngonyango lwemitha." Kodwa isayensi yezonyango iyaphucuka imihla ngemihla. Namhlanje siza kuthetha ngenye indlela yonyango ephucukileyo, ekhawulezayo kakhulu ejolise kuphela kwiiseli zomhlaza kwaye inciphisa kakhulu umonakalo kwiiseli eziphilileyo. Oku kubizwa ngokuba yi-VMAT.
Ngoko ke, yintoni le VMAT?
Ngamafutshane, i-VMAT sisifinyezo segama elithi 'Volumetric Modulated Arc Therapy'. Olu lunyango lwemitha oluphambili kakhulu olusetyenziselwa ukubulala iiseli zomhlaza. Ngokuchanekileyo, luhlobo lwe-External Beam Radiation Therapy (EBRT). Oku kuthetha ukuba akukho zinto zemitha ezifakwa emzimbeni wakho. Ngoko ke akukho mfuneko yokukhathazeka malunga nemitha ephuma emzimbeni wakho ngexesha okanye emva konyango.
Khawuthelekelele, njengoko ulele ebhedini, umatshini omkhulu ujikeleza kancinci kancinci, ujolise imisebe yemitha rhoqo, ujolise kuphela kwindawo apho umhlaza ukhoyo. Yiloo nto eyenzekayo ngetekhnoloji ye-VMAT.
Le yinguqulelo ephucukileyo yendlela yonyango lwemitha, i-IMRT (Intensity-Modulated Radiation Therapy). Kwi-IMRT, endaweni yomqadi omnye omkhulu wemitha, imiqadi emininzi emincinci yemitha kwiindlela ezahlukeneyo ithunyelwa kwi-tumor. Oku kunciphisa kakhulu umonakalo kwizicubu eziphilileyo ezijikeleze i-tumor. Kwi-VMAT, le nkqubo ifanayo yenzeka ngelixa umatshini ujikeleza rhoqo, ngoko ke unyango lunokwenziwa ngokuchanekileyo nangokukhawuleza .
Zeziphi iintlobo zomhlaza ezisetyenziselwa unyango lwe-VMAT?
Ngenxa yokuchaneka kwetekhnoloji ye-VMAT, sisisombululo esihle kakhulu sokunyanga iithumba zomhlaza ezinemilo engaqhelekanga okanye ezikufutshane kakhulu nezitho ezibalulekileyo emzimbeni wethu. Umzekelo, ugqirha wakho wezifo zomhlaza angacebisa le ndlela yokunyanga umhlaza okhulele kwilungu elithile.
Unyango lwe-VMAT lusetyenziswa kakhulu kwezi ntlobo zilandelayo zomhlaza.
| Iintlobo zomhlaza apho unyango lwe-VMAT lusetyenziswa kakhulu khona | |
|---|---|
| Umhlaza weprostate | Umhlaza webele |
| Umhlaza wentloko nentamo | Umhlaza womlomo wesibeleko |
| Umhlaza wemiphunga | Umhlaza weColoral |
| Umhlaza wempundu | Umhlaza wesisu |
| Umhlaza wobuchopho | Umhlaza wempumlo/umqala |
Kusebenza njani oku? Kwenzeka ntoni ngaphambi konyango?
Unyango lwe-VMAT luyinkqubo ecwangcisiweyo kakhulu. Lubandakanya amanyathelo aliqela abalulekileyo.
1. Ucwangciso Lonyango (Ucwangciso kunye nokulinganisa)
Eli lelona nyathelo libalulekileyo. Iqela lakho lezonyango liza kuqala lithathe imifanekiso yomzimba wakho enamacala amathathu (3D). Oku kudla ngokwenziwa kusetyenziswa i-CT scan, kodwa ngamanye amaxesha kwenziwa i-MRI okanye i-PET scan. Le mifanekiso iya kubanceda baqonde ngqo apho umhlaza ukhoyo, ubungakanani bawo, imilo yawo, kunye nawo nawaphi na amalungu aphilileyo ajikelezileyo afuna ukukhuselwa kwimitha.
Emva koko kukho iseshoni yokucwangcisa ebizwa ngokuba yi "simulation". Apha,
- Uza kubekwa kwindawo efanelekileyo kwisofa yonyango kwaye umqadi wemitha uza kubekwa ngendlela yokuba ufikelele ngqo kumhlaza.
- Ungasebenzisa uphawu lwexeshana okanye uphawu olusisigxina, olufana netattoo encinci, eluswini lwakho ukuphawula indawo echanekileyo yomhlaza.
- Ungasebenzisa nesikhunta okanye imaski eyenzelwe ngokukodwa umzimba wakho ukuze uhlale ukwindawo efanayo ngaphandle kokunyakaza ngexesha lonyango.
Le nkqubo yokucwangcisa ingathatha usuku okanye iintsuku ezininzi, njengoko unyango kufuneka lulungiselelwe imo yomhlaza wakho ngokuchanekileyo, kusetyenziswa imisebe yemitha emincinci njengencam yepensile (2.5 x 5 millimeters).
2. Ngexesha le-VMAT
Ingcali ye-radiation therapist iza kukubeka ebhedini yonyango kwindawo efanayo naleyo ubukuyo ngexesha leseshoni yokucwangcisa. Emva koko iza kulawula umatshini ohambisa i-radiation, obizwa ngokuba yi-``LINAC - Linear Accelerator'', kwigumbi elahlukileyo. Uya kukwazi ukuthetha naye ngemakrofoni.
Xa unyango luqala, umatshini we-LINAC ujikeleza kancinci ujikeleze wena. Njengoko ujikeleza, imisebe yemitha yeemilo ezahlukeneyo kunye namandla ijoliswe kwithumba. Awuyi kuva le misebe yemitha, kwaye awuyi kuva ntlungu. Ingcali ye-radiation therapist iya kujonga yonke into ngononophelo kwisikrini sekhompyutha.
Nangona lonke ixesha lonyango lithatha malunga nemizuzu engama-20, i-radiation inikezelwa ixesha elifutshane kakhulu, malunga nemizuzu emibini. Ixesha eliseleyo lichithwa likubeke kwindawo efanelekileyo.
3. Emva konyango (Emva kwe-VMAT)
Nje ukuba iseshoni yonyango iphelile, ungaya ekhaya uqalise imisebenzi yakho yemihla ngemihla njengesiqhelo.
Zithini iingenelo zonyango lwe-VMAT?
Kukho iingenelo ezimbini eziphambili zonyango lwe-VMAT: ukuchaneka kunye nesantya.
Ukuchaneka: Ekubeni iteknoloji ye-VMAT ijolise kwi-tumor kwaye ikhupha imitha, umonakalo kwizicubu eziphilileyo ezijikelezileyo uncinci. Le yeyona nzuzo inkulu.
Isantya: Iseshoni yonyango enye ingagqitywa ngemizuzu embalwa. Okukhona unyango lukhawuleza, kokukhona ixesha elincinci lokuhlala kwindawo efanayo. Kwaye kokukhona unyango luchaneke ngakumbi.
Ngaba kukho naziphi na iziphumo ebezingalindelekanga?
Ekubeni unyango lwe-VMAT lubangela umonakalo omncinci kwizicwili eziphilileyo, umngcipheko weziphumo ebezingalindelekanga nawo uphantsi. Nangona kunjalo, umonakalo othile kwiiseli eziphilileyo awunakuthintelwa. Nokuba iziphumo ebezingalindelekanga zenzeka okanye azikho, kwaye ziyintoni na, ziyahluka ngokuxhomekeke kwindawo yomzimba onyangwayo .
| Imiphumela | Inkcazo |
|---|---|
| Ukudinwa | Le yeyona miphumo ixhaphakileyo. |
| Isicaphucaphu nokuhlanza | Oku kunokwenzeka ngakumbi xa kunyangwa indawo yesisu. |
| Urhudo | Inokwenzeka xa kunyangwa isisu okanye indawo ye-pelvic. |
| Ukulahleka kweenwele | Xa kunyangwa intloko okanye intamo, kwenzeka kuphela kuloo ndawo. |
| Utshintsho lolusu | Ubomvu, ukoma, ukurhawuzelela, okanye ukudumba kolusu kwindawo enyangiweyo. |
Amava omntu wonke ahlukile. Abanye abantu banokuziva bebhetele kwangoko emva konyango. Abanye banokuthatha iinyanga ezininzi ukuba baphile ngokupheleleyo. Buza ugqirha wakho ukuba ulindele ntoni ngokusekelwe kwimeko yakho yempilo.
Uza kunikwa amaxesha okulandela emva konyango lwakho. Qiniseka ukuba uya kuzo zonke ezi zihlandlo. Thetha nogqirha wakho malunga nazo naziphi na iimpawu okanye iziphumo ebezingalindelekanga onokuba nazo.
Umyalezo Wokuya Ekhaya
- I-VMAT yindlela yonyango lwemitha ephucukileyo nechanekileyo ejolise kuphela kwiiseli zomhlaza kwaye inciphise umonakalo kwizicubu ezisempilweni.
- Ezi seshoni zonyango zikhawuleza kakhulu. Kuthatha imizuzu embalwa nje ukuhambisa imitha.
- Ngenxa yokuchaneka okukhulu, amathuba okuba neziphumo ebezingalindelekanga mancinci kunakwindlela yonyango lwemitha yesiqhelo.
- Akukho ntlungu ngexesha lonyango, kwaye ungagoduka njengesiqhelo emva konyango.
- Thetha ngokukhululekileyo nogqirha wakho we-oncologist malunga nokuba olu nyango lukulungele na kunye neziphumo ezinokubakho kunye nemiphumo emibi.
