Igama elithi "ukwelashwa ngemisebe" lingase lizwakale lithusa kancane kuwe. Kodwa kuyindlela yokwelapha ebaluleke kakhulu futhi enamandla lapho ulwa nomdlavuza. Namuhla sizokhuluma ngenye yezindlela zokwelapha ngemisebe ezintsha, ezithuthukisiwe kakhulu neziphephile kakhulu. Leyo yi-VMAT. Ake sibone ukuthi iyini, isebenza kanjani, nokuthi yiziphi izinzuzo zayo.
Kalula nje, iyini le VMAT?
I-VMAT imele i- Volumetric Modulated Arc Therapy . Lokhu ukwelashwa okusebenzisa imisebe evela ngaphandle komzimba ukubulala amangqamuzana omdlavuza. Kwezokwelapha, lokhu sikubiza ngokuthi i-External Beam Radiation Therapy (EBRT).
Cabanga nje, ufuna ukubhubhisa isimila esinomdlavuza emzimbeni wakho, kodwa ngaphandle kokulimaza izitho ezinempilo nezinhle ezizungezile. Yilapho ubuchwepheshe be-VMAT buba yinto ebaluleke kakhulu.
Yilokhu okwenzekayo kulokhu kwelashwa:
Ngesikhathi ulele embhedeni wokwelashwa, umshini omkhulu okhipha imisebe ujikeleza nxazonke zakho ngesiyingi esisodwa noma ngaphezulu. Lo mshini awukushayi. Kodwa njengoba ujikeleza, uhlose ngqo umdlavuza futhi ukhipha inani elidingekayo lemisebe.
Into ebaluleke kakhulu ukuthi akukho zinto ezikhipha imisebe emzimbeni wakho phakathi nalokhu kwelashwa. Ngakho-ke asikho isidingo sokukhathazeka ngokuthi umzimba wakho uzoba nemisebe ngesikhathi noma ngemva kokwelashwa.
I-VMAT inguqulo ethuthukisiwe yokwelashwa kwe-IMRT (Intensity-Modulated Radiation Therapy) esekusetshenziswe kakade. Esikhundleni sokusebenzisa umsebe owodwa omkhulu wemisebe, i-IMRT isebenzisa imisebe eminingi emincane ukuletha imisebe esigaxeni. Ku-VMAT, le nqubo yenziwa ngenkathi umshini ujikeleza njalo (njenge-arc), ngakho-ke isikhathi sokwelashwa sifushane kakhulu.
Yiziphi izinhlobo zomdlavuza ezisetshenziselwa ukwelashwa kwe-VMAT?
Ngenxa yokunemba kobuchwepheshe be-VMAT, iyisisombululo esifanele sokwelapha izimila ngezimo ezingavamile, noma izimila eziseduze nezitho ezizwelayo njengobuchopho, inhliziyo, noma umgogodla. Cabanga ngesimila esikhule sizungeze isitho esibalulekile. Esimweni esinjalo, i-VMAT ingelapha umdlavuza kuphela ngaphandle kokulimaza isitho esinempilo.
Ngezansi kunezinye zezinhlobo zomdlavuza ezivame ukusetshenziswa kakhulu ngale ndlela yokwelapha.
| Uhlobo lomdlavuza | Izitho zomzimba eziphathwa njalo |
|---|---|
| Umdlavuza wekhanda nentamo | Ngemuva kwekhala (i-Nasopharyngeal), umphimbo (i-Oropharyngeal) |
| Umdlavuza webele | Umdlavuza wamaphaphu, umdlavuza webele, umdlavuza womphimbo |
| Umdlavuza wesisu kanye nowesinqe | Umdlavuza we-prostate, umdlavuza wesibeletho, umdlavuza we-rectal, umdlavuza wamathumbu amakhulu |
| Isistimu yezinzwa ephakathi | Umdlavuza wobuchopho |
Lo mshini we-VMAT usebenza kanjani?
Umgomo oyinhloko wale ndlela ukuletha umthamo obhubhisayo wemisebe esigaxeni somdlavuza ngenkathi kunciphisa umonakalo ezicutshini ezinempilo.
Njengoba umshini othi ``Medical Linear Accelerator - LINAC`` ujikeleza nxazonke zakho, ushintsha njalo isimo namandla okukhanya kwemisebe okukhiphayo. Lokhu kwenzeka ngqo ukuze kufane nesimo se-three-dimensional (3D) sesimila somdlavuza. Lo mthamo wokukhanya ophakeme ulimaza i-DNA yamaseli omdlavuza, uwabulale. Ngesikhathi esifanayo, lo mshini uyaqikelela ukugcina inani lokukhanya elitholwa amaseli aphilile azungezile lisezingeni eliphansi kakhulu.
Kwenzekani ngaphambi kokuba ukwelashwa kuqale? (Isigaba sokuhlela)
Ingxenye ebaluleke kakhulu yempumelelo yokwelashwa kwe-VMAT yilesi sigaba sokuhlela . Kufana nokudweba imephu ngaphambi kokuya empini bese uphawula ngqo ukuthi isitha sikuphi.
Udokotela wakho womdlavuza kanye nethimba lezokwelapha bazochitha izinsuku eziningana kulokhu.
1. Ukuthwebula Izithombe ze-3D: Okokuqala, kwenziwa i-CT scan, i-MRI, noma i-PET scan ukuze kutholakale izithombe ze-3D ezicacile zendawo yomzimba wakho lapho umdlavuza ukhona khona. Lezi zithombe zibonisa usayizi oqondile, ukuma, kanye nendawo yesimila. Ziphinde zihlonze noma yiziphi izitho ezinempilo ezidinga ukuvikelwa emisebeni.
2. Iseshini Yokusetha (Ukulingisa):Okulandelayo, uzoyiswa esimisweni esikhethekile esibizwa ngokuthi "Ukulingisa." Lapha, uzobekwa embhedeni wokwelashwa futhi indawo efanele okufanele ube kuyo ngesikhathi sokwelashwa izonqunywa.
3. Ukumaka nokusekela: Ngenxa yokuthi udinga ukuhlala endaweni efanayo ngesikhathi ngasinye sokwelashwa, ngezinye izikhathi kuba namamaki esikhashana esikhumbeni sakho, njengokusebenzisa ipeni. Ngezinye izikhathi kungafakwa umaki omncane kakhulu, ohlala njalo, njengokudweba umzimba, futhi, ngenxa yokuthi ngeke ukwazi ukunyakaza ngesikhathi sokwelashwa, kungasetshenziswa isisekelo, njengesikhunta esenzelwe umzimba wakho ngqo noma imaski egqokwa ebusweni bakho.
4. Ukuhlela imisebe yemisebe: Ithimba lezokwelapha libe selihlela ukuthi imisebe yemisebe iqondiswe esimila ngosizo lwesofthiwe yekhompyutha.
Cabanga nje, lobu buchwepheshe bungalawula imisebe yemisebe endaweni encane njengesihloko sepensela, okungukuthi, amamilimitha angu-2.5 x 5. Kunembile kangako.
Kwenzekani ngesikhathi sokwelashwa?
Uma ufika ngosuku lokwelashwa kwakho, udokotela wezokwelapha ngemisebe uzokubeka embhedeni njengoba kuhleliwe. Uzobe esesebenzisa umshini esegumbini elihlukile. Kodwa-ke, uzokwazi ukukhuluma naye ngemakrofoni.
Umshini ujikeleza kancane kancane eduze kwakho. Njengoba ujikeleza, imisebe yemisebe yezimo ezahlukene namandla iqondiswe esigaxeni. Ngeke uzizwe le misebe yemisebe. Uchwepheshe wezokwelapha ngemisebe ubuka yonke inqubo bukhoma esikrinini sekhompyutha. Ngakho-ke bangaqinisekisa ukuthi umthamo oqondile ulethwa endaweni efanele.
Kuthatha isikhathi esingakanani iseshini yokwelashwa?
Isikhathi sonke sokwelashwa singathatha cishe imizuzu engama-20 . Kodwa isikhathi esiningi sichithwa sikubeka endaweni efanele. Inqubo yangempela yomshini ujikeleza futhi uletha imisebe ithatha isikhathi esifushane kakhulu, cishe imizuzu emibili.
Kuye ngohlobo kanye nesigaba somdlavuza wakho, kungadingeka ukuthi uze kulezi zikhathi zokwelapha nsuku zonke amasonto amaningana. Udokotela wakho uzokuchazela uhlelo. Ungaya ekhaya ngokujwayelekile ngemva kokwelashwa.
Yiziphi izinzuzo zokwelashwa kwe-VMAT?
Izinzuzo ezimbili eziyinhloko zobuchwepheshe be-VMAT ukunemba kanye nesivinini .
| Inzuzo | Incazelo |
|---|---|
| Ukunemba | Ngokuhlasela kuphela isimila somdlavuza, imisebe ivinjelwa kakhulu ekufinyeleleni izicubu nezitho ezizungezile ezinempilo. Lokhu kunciphisa kakhulu ingozi yemiphumela emibi. |
| Isivinini | Iseshini yokwelashwa eyodwa iqedwa ngokushesha okukhulu, ithatha cishe imizuzu emibili. Uma ukwelashwa kushesha, kulapho-ke isikhathi esincane sokuhlala endaweni eyodwa. Futhi, kuthatha isikhathi esincane osukwini lwakho. |
Ingabe ikhona imiphumela emibi?
Ngenxa yokuthi ubuchwepheshe be-VMAT abudali umonakalo omncane kakhulu kumaseli anempilo, ingozi yemiphumela emibi iphansi kakhulu. Kodwa-ke, izinga elithile lomonakalo wamaseli lingase lingavinjelwa.
Imiphumela emibi eyenzeka incike kakhulu endaweni yomzimba elashwe kuyo. Lokhu kuvame ukuba okwesikhashana.
| Umphumela ongemuhle | Incazelo |
|---|---|
| Ukukhathala | Lona umphumela ovame ukubonakala kakhulu. |
