Uninzi lwethu luyoyika xa sisiva igama elithi umhlaza. Sikwanoloyiko olukhulu lonyango lwemitha . Kuqhelekile ukucinga, "Owu, ngaba oku kuya kuchaphazela namalungu omzimba asempilweni?" Kodwa ubuchwepheshe banamhlanje buphucuke kakhulu. Namhlanje sithetha ngesicwangciso sonyango lwemitha esikhethekileyo esijolise ngqo kwithumba lomhlaza kwaye sinciphise umonakalo kwizitho eziphilileyo ezingqongileyo. Oko yi-3D-CRT.
Yintoni le 3D-CRT?
Ngamafutshane, i-3D-CRT yindlela ephucukileyo kakhulu esetyenziselwa ukucwangcisa unyango lwemitha ye-External Beam Radiation Therapy (EBRT) yomhlaza. Ayilonyango ngokwalo, kodwa yisicwangciso sonyango .
Khawuthelekelele uye kumthungi ukuze akuthungele ilokhwe. Uthatha imilinganiselo yakho echanekileyo aze ayithunge ilokhwe ukuze ilingane kakuhle, akunjalo? I-3D-CRT injalo. Apha, iingcali zomhlaza wemitha zifumana umbono oneemilinganiselo ezintathu (3D) wethumba lakho lomhlaza kunye namalungu aphilileyo alijikelezileyo.
Ukuze ufumane le mbono ye-3D, kusetyenziswa imifanekiso evela kuvavanyo lokuxilonga olufana ne-'CT (Computed Tomography)` scan, ` MRI (Magnetic Resonance Imaging)` scan, okanye i-`PET ( Positron Emission Tomography )` scan. Isoftware yekhompyutha ekhethekileyo ihlalutya le mifanekiso kwaye idale `imephu ye-3D` yobukhulu obuchanekileyo, imo, kunye nendawo yomhlaza.
Le mephu ye-3D ivumela ukuba imisebe yemitha ijoliswe ngqo kwithumba elinomhlaza, nto leyo enciphisa kakhulu umonakalo obangelwa yimisebe kwizitho eziphilileyo ezingqongileyo ezifana nemiphunga, intliziyo nesibindi .
Ziziphi iindlela zokusebenzisa i-3D-CRT?
Iingcali zomhlaza zisebenzisa le ndlela yokucwangcisa i-3D-CRT ukunyanga iintlobo ezahlukeneyo zomhlaza. Le ndlela ibaluleke kakhulu kwiimeko apho utyando lungenakwenzeka. Ikwabonelela ngonyango olucwangcisiweyo lwemitha ukunciphisa ithumba ngaphambi kotyando (`unyango lwe-neoadjuvant`) okanye ukutshabalalisa naziphi na iiseli zomhlaza eziseleyo emva kotyando (`unyango lwe-adjuvant`).
Apha ngezantsi kukho ezinye zezona ntlobo zixhaphakileyo zomhlaza ezisetyenziselwa i-3D-CRT.
| Uhlobo lomhlaza | Iinkcukacha ezithe xaxe |
|---|---|
| Umhlaza wempundu | Ukucwangcisa unyango nokuba lutyando okanye alutyandwanga. |
| Umhlaza wamathumbu | Ihlala isetyenziselwa ukunciphisa ithumba ngaphambi kotyando. |
| Umhlaza webele | Kwimeko apho umngcipheko wokuphinda ubuye uphezulu emva konyango. |
| Umhlaza weColoral | Xa sele isasazeke emiphungeni okanye esibindini kwaye utyando alunakwenzeka. |
| Umhlaza wentloko nentamo | Umzekelo: Umhlaza weLaryngeal kunye nomhlaza weNasopharyngeal. |
| Umhlaza wenkqubo yokugaya ukutya | Umzekelo: Umhlaza wesinyi senyongo kunye nomhlaza we-bile duct. |
| Umhlaza weprostate | Isetyenziswa kuzo zombini iimeko zokuqala nezexesha elide. |
| Umhlaza wemiphunga | Njengonyango oluphambili xa utyando lungenakwenzeka. |
| Eminye imihlaza | Ikwasetyenziswa nakwezinye iintlobo zomhlaza ezifana ne-'Ewing sarcoma', 'Vulvar cancer', 'Wilms tumor'. |
Isetyenziswa njani i-3D-CRT kucwangciso lonyango?
Iqela lakho lezonyango liza kukufundisa le nkqubo yokucwangcisa ye-3D-CRT inyathelo ngenyathelo.
1. Ukudala iMephu ye-3D
Okokuqala, njengoko besitshilo ngaphambili, imifanekiso evela kwiiskeni zakho ze-CT kunye ne-MRI iyathathwa kwaye inkqubo yekhompyutha yenza imephu ye-3D yethumba. Le mephu ifakwa kumatshini ohambisa imitha (i-`Linear Accelerator`).
2. Inkqubo yokulinganisa
Oku kufana nokuziqhelanisa nomdlalo weqonga. Uza kulaliswa etafileni yonyango uze ubekwe ngendlela oza kufumana ngayo unyango lwemitha. Kule ndawo, imephu ye-3D iza kusetyenziswa ukumisela indawo echanekileyo kunye ne-engile yemitha yemitha.
3. Ukufaka iimpawu zolusu
Ngexesha lokulinganisa, iqela lezonyango liza kubeka amabala amancinci kakhulu, afana namachaphaza eluswini lwakho. La ngamabala amancinci ('iitattoo') adla ngokuba ziitattoo ezihlala zihleli . Musa ukoyika xa uzibona. Ezi zibekwe ngendlela yokuba ngexesha lonyango ngalunye, umsebe wemitha uqondiswe ngqo apho kukho iiseli zomhlaza, ngaphandle kokuhamba nemilimitha enye. La manqaku aya kukunceda ugcine umzimba wakho ukwindawo efanayo ngexesha lonyango ngalunye.
Ngaba i-3D-CRT ibangela iziphumo ebezingalindelekanga?
Into ebalulekileyo ekufuneka uyiqonde apha kukuba i-3D-CRT yindlela yokucwangcisa , hayi unyango. Ke ngoko, akukho miphumo mibi ebangelwa yinkqubo yokucwangcisa i-3D-CRT.
Nangona kunjalo, unyango lwemitha olunikezelwa ngokwesicwangciso lunokubangela ezinye iziphumo ebezingalindelekanga. Nangona i-3D-CRT inciphisa kakhulu umonakalo kwizicwili eziphilileyo, umonakalo othile usenokwenzeka. Iziphumo ebezingalindelekanga ezenzekayo zixhomekeke kwindawo yomzimba onyangwayo.
| Imiphumela | Ingcaciso elula |
|---|---|
| Ukudinwa | Ingxaki eqhelekileyo eyenzeka njengoko umzimba ulwa neeseli zomhlaza kwaye ngenxa yonyango. |
| Isicaphucaphu nokuhlanza | Oku kunokwenzeka ngakumbi xa kunyangwa indawo yesisu. |
| Umnqweno wokutya | Unyango lunokubangela utshintsho kwincasa. |
| Intloko ebuhlungu | Inokwenzeka xa kunyangwa indawo yentloko. |
| Utshintsho lolusu | Ububomvu, ukoma, ukurhawuzelela, okanye intlungu kwindawo yonyango. |
| I-Dysuria | Inokwenzeka xa kunyangwa isisu esisezantsi okanye indawo ye-pelvic. |
| Urhudo | Inokwenzeka xa kunyangwa indawo yamathumbu. |
Iingenelo kunye netekhnoloji yanamhlanje ye-3D-CRTs
Eyona nzuzo inkulu yendlela ye-3D-CRT kukuba ijolise kwithumba ngokuchanekileyo kwaye inciphisa umonakalo kwizicwili eziphilileyo ezijikelezileyo.
Nangona kunjalo, namhlanje kukho iindlela zokucwangcisa unyango lwemitha eziphucukileyo kune-3D-CRT. Enye yazo yi-'Intensity-Modulated Radiation Therapy (IMRT)'.
I-IMRT isebenzisa imisebe emininzi emincinci (ii-beamlets) endaweni yomsebe omnye omkhulu. Ubukhali bemisebe bungalungiswa. Kufana nokupeyinta umfanekiso ngemigca emincinci, eyahlukeneyo yepeyinti, endaweni yombala omnye. Oku kuvumela i-IMRT ukuba inike imitha ehambelana ngcono nohlobo oluntsonkothileyo lwethumba. Ezinye izifundo zibonisa ukuba i-IMRT inokuba nemiphumo emibi embalwa nangakumbi.
Kodwa ukuba i-3D-CRT, i-IMRT, okanye enye indlela ikulungele na, kuxhomekeka kwiqela lakho lonyango lomhlaza. Oku kuxhomekeke kwizinto ezininzi, kuquka uhlobo, indawo, kunye nobukhulu bomhlaza wakho.
Ukuba unikwe unyango lwe-radiation, ungoyiki ukubuza ugqirha wakho okanye iqela lezonyango ngale nkqubo. Kuya kuba luncedo kakhulu kuwe ukwazi yonke into ngokucacileyo.
Umyalezo Wokuya Ekhaya
