Ijambo "imirasire" rishobora gutuma ugira ubwoba gato. Cyane cyane iyo bigeze ku kuvura kanseri, ubwo bwoba bushobora kuba bwinshi kurushaho. Ariko ikoranabuhanga ryateye imbere cyane muri iyi minsi. Bitandukanye n'uko byari bimeze kera, ubu buryo bwo kuvura ubu bushobora gukorwa neza kandi witonze. Uyu munsi rero turimo kuvuga ku kuvura kanseri hakoreshejwe imirasire isanzwe, External Beam Radiation Therapy, cyangwa EBRT mu magambo ahinnye.
Mu magambo make, EBRT ni iki?
Tekereza uryamye neza ku buriri. Imashini nini iri kure irimo kurasa imirasire yakozwe neza, igamije gusa ikibyimba kiri mu mubiri wawe. Ibyo ni byo twita EBRT.
Ibi bikubiyemo gukoresha imirasire ifite ingufu nyinshi mu gusenya uturemangingo twa kanseri. Intego nyamukuru ni ukugabanya kwangirika kw'uturemangingo tuzima tuyikikije mu gihe hangirika uturemangingo twa kanseri. Ubu ni uburyo bwo kuvura inyuma, bityo nta kintu na kimwe gishyirwa mu mubiri wawe.
Muri ubu buryo bwo kuvura, imashini ikoresha imirasire ntizigera ikora ku mubiri wawe. Ahubwo, itsinda ry’abaganga ritegura iyo mashini kugira ngo yibasire uturemangingo twa kanseri gusa kure, maze iratwike.
Ni irihe tandukaniro riri hagati yo kuvurwa hakoreshejwe imirasire yo hanze n'iyo mu mubiri?
Ubuvuzi bushingiye ku mirasire bushobora kugabanywamo ubwoko bubiri bw'ingenzi.
1. Ubu buryo bwo kuvura imirasire y'inyuma (EBRT): Ubu ni bwo buryo tuvuga. Bukubiyemo gutanga imirasire iturutse mu mashini iri hanze y'umubiri.
2. Ubuvuzi bw'imirasire y'imbere: Ibi bikubiyemo kubaga no gushyira icyuma gito gikoresha imirasire imbere cyangwa hafi y'ikibyimba.
Nubwo ubu buryo bwombi busenya uturemangingo twa kanseri, uburyo bubikora buratandukanye.
Ni ubuhe bwoko bw'imirasire y'ingufu ikoreshwa muri ubu buryo bwo kuvura?
Imirasire ni urumuri rw'ingufu rurimo uduce duto cyane. Utu duce dufite imbaraga zo gusenya uturemangingo twa kanseri. Ikibazo nyamukuru cy'ubu buryo bwo kuvura ni ugusenya uturemangingo twa kanseri gusa nta kwangiza uturemangingo tuzima. Ubwoko butandukanye bw'uduce bukoreshwa muri ibi.
- Fotoni (imirasire ya X na gamma): Izi ni zo zikoreshwa cyane mu kuvura EBRT. Zimeze nka X-ray zikoresha imbaraga nyinshi. Zishobora kwinjira cyane mu mubiri wawe no kwica uturemangingo twa kanseri.
- Porotoni:Utu ni uduce dufite amashanyarazi meza. Uburyo bwo kuvura hakoreshejwe utu tunyangingo bwitwa `(Proton Therapy)`. Ubu ni ikoranabuhanga rishya. Umwihariko hano ni uko nyuma y’uko uruziga rwa proton rugeze kuri kanseri, ruhagarara rutarenze aho. Kubwibyo, kwangirika kw'uturemangingo tuzima turi iruhande rwa kanseri ni gato cyane. Ariko, ubu buryo bwo kuvura ntabwo bukunze kugaragara cyane ku isi.
- Electron: Izi ni uduce duto dufite amashanyarazi mabi. Ntidushobora kugenda mu bwihisho nka fotoni cyangwa porotoni. Kubwibyo, zikoreshwa cyane mu kuvura ibibyimba biri ku buso bw'umubiri, nka kanseri y'uruhu.
Ubuvuzi bwinshi bwa EBRT bukoresha imashini yitwa ``Linear Accelerator`` cyangwa ``LINAC``` kugira ngo yihutishe utwo duce no kuduha uturemangingo twa kanseri.
Ese hari ubwoko butandukanye bw'ubuvuzi bwa EBRT?
Yego, bitewe n’iterambere ry’ikoranabuhanga, ubu hari ingamba zitandukanye n’ubwoko butandukanye bwo kuvura kanseri ya EBRT. Bitewe n’imiterere n’aho kanseri yawe iherereye, muganga wawe azahitamo uburyo bukubereye.
| Ubwoko bw'ubuvuzi | Mu magambo make ... (Ibisobanuro Byoroshye) |
|---|---|
| Ubuvuzi bwa 3D Conformal Radiation | Hakoreshejwe ibintu nka CT scans, hakorwa icyitegererezo cya kanseri gifite imiterere itatu (3D) kandi imirasire y'imirasire irayireba mu mpande zitandukanye kugira ngo ihuze nayo. |
| Ubuvuzi bw'imirasire ikoresheje imbaraga (IMRT) | Ubu ni uburyo bugezweho bwa 3D. Aha, ntabwo ari imiterere y'ikibyimba gusa ishobora kwibasirwa, ahubwo n'uduce dufite uturemangingo twinshi twa kanseri dushobora kwibasirwa n'imbaraga nyinshi , kandi uduce dufite uturemangingo twinshi twa kanseri dushobora kwibasirwa n'imbaraga nke . |
| Ubuvuzi bushingiye ku mirasire (IGRT) bukoresha amashusho | Mbere ya buri buryo bwo kuvurwa, hafatwa isuzuma (nk'isuzuma rya CT) kugira ngo hamenyekane neza aho kanseri iherereye hanyuma imirasire igatangwa. Ibi bituma ubuziranenge buba buri hejuru cyane. |
| Kubaga hakoreshejwe imirasire ya stereotactic (urugero: Gamma Knife) | Ubu si ukubaga, nubwo byitwa "kubaga." Ni uburyo bwo gutanga imirasire myinshi cyane ku tubyimba duto two mu bwonko, haba mu rukingo rumwe cyangwa mu rukingo rwinshi, mu buryo busobanutse neza. |
| Ubuvuzi bw'imirasire y'umubiri mu buryo bwa stereotactic (SBRT) | Ubu buryo ni bumwe n’ubwo twavuze haruguru, ariko bukoreshwa kuri kanseri ziboneka hanze y’ubwonko, cyane cyane ahantu nko mu bihaha, umwijima, n’umugongo. |
| Imirasire yo mu gihe cyo kubagwa (IORT) | Ibi bikorwa mu gihe cyo kubaga kugira ngo kanseri ikureho. Imirasire itangwa icyarimwe ku bice bya kanseri bitashoboraga gukurwaho burundu no kubagwa. |
Ni ubuhe bwoko bw'indwara ziterwa n'ubuvuzi bwa EBRT?
Ubu buryo bwo kuvura bukoreshwa mu bikorwa byinshi by'ingenzi.
- Mu gusenya uturemangingo twa kanseri: EBRT ikoreshwa nk'uburyo bw'ibanze bwo kuvura ubwoko bwinshi bwa kanseri.
- Kugira ngo ishyigikire ubundi buryo bwo kuvura: Ikoreshwa mu kugabanya ikibyimba mbere yo kubagwa (neo-adjuvant therapy) cyangwa mu gusenya uturemangingo twa kanseri dukekwaho kuba twasigaye nyuma yo kubagwa no gukumira kanseri kugaruka (adjuvant therapy).
- Kugabanya ibimenyetso: Nubwo rimwe na rimwe kanseri idashobora gukira burundu, ubu buryo bufasha mu kugenzura ibimenyetso nk'ububabare buterwa n'ibibyimba bya kanseri no kubungabunga ubuzima bw'umurwayi.
Ubwoko bwa kanseri buvurwa na EBRT
EBRT ni uburyo bukomeye bwo kuvura ubwoko bwinshi bwa kanseri isanzwe, nka:
- Kanseri y'ibere
- Kanseri y'umura munini
- Kanseri y'ibihaha
- Kanseri ya porositate
- Kanseri yo mu mura
- Kanseri yo mu mutwe no mu ijosi
- Kanseri z'amaraso nka kanseri y'amaraso (leukemia) na kanseri y'amaraso (lymphoma).
Ni iki kibaho mbere yo kuvurwa? (Icyiciro cyo gutegura)
Iki cyiciro cyo gutegura, kizwi kandi nka "simulation", ni igice cy'ingenzi mu gutuma ubuvuzi bwa EBRT bugira icyo bugeraho. Kirimo gutegura byose ku nshuro ya mbere.
1. Aho umuntu aherereye:Uzaba uri ku buriri kuri uyu munsi wo gutegura, nkuko wari uri mu gihe cyo kuvurwa.
2. Gupima: Hanyuma, hakorwa isuzuma rya CT, MRI, cyangwa PET kugira ngo haboneke amashusho nyayo ya kanseri yawe n'ingingo zizima ziyikikije. Ibi nibyo bifasha kumenya ingano nyayo, imiterere, n'aho kanseri iherereye.
3. Gushyiramo ikimenyetso: Hanyuma, uduce duto cyane, tumeze nk'utudomo tuzashyirwa ku ruhu rwawe hakoreshejwe ikaramu kugira ngo tumenye aho ugomba kuvurwa. Ibi bigomba kuguma aho biri kugeza igihe cyo kuvurwa kirangiye.
4. Gukora udupfukamunwa/udupfukamunwa: Kugira ngo bigufashe kuguma uhagaze mu gihe cyo kuvurwa, ushobora gukora udupfukamunwa twabigenewe cyangwa udupfukamunwa dukwiranye n'igice cy'umubiri wawe.
Bakoresheje aya makuru, itsinda ry'abaganga bazamara iminsi myinshi bakora gahunda y'ubuvuzi ikubereye.
Ni iki kibaho mu gihe cyo kuvurwa?
Nta bubabare uzumva mu gihe cyo kuvurwa.
Uzashyirwa mu mwanya umwe n'uwo wari uri mu gihe cyo kwigana. Nibiba ngombwa, uzahabwa agapfukamunwa kadasanzwe cyangwa agapfukamunwa. Hanyuma umuvuzi w'imirasire azasohoka mu cyumba agacana imashini. Ariko , bashobora kukwitegereza kuri ecran bakavugana nawe bakoresheje intercom .
Imashini irazenguruka hirya no hino, igakora amajwi atandukanye, kandi ishyira imirasire ahantu runaka. Icyo ugomba gukora ni ugutuza, gutuza, no guhumeka nk'uko bisanzwe. Uburyo bwose bwo kuyivura bushobora gufata iminota 15-30. Ariko, imirasire ikoreshwa mu minota mike gusa.
Ni izihe ngaruka mbi zikunze kugaragara?
Nubwo twagerageza kugabanya kwangirika kw'uturemangingo tuzima uko bishoboka kose, biragoye kwirinda kwangirika kumwe. Kwangirika kw'utu turemangingo tuzima ni byo bitera ingaruka mbi.
Icy'ingenzi ni uko izi ngaruka mbi atari zimwe kuri buri wese . Ziterwa kandi n'igice cy'umubiri givurwa n'imirasire. Urugero, umuntu uvurwa ku mutwe ashobora gutakaza umusatsi, ariko umuntu uvurwa ku nda ashobora kutabigeraho.
Zimwe mu ngaruka mbi zikunze kugaragara ni izi:
- Kumva unaniwe cyane (Umunaniro): Iyi ni yo ngaruka ikunze kugaragara cyane.
- Isesemi no kuruka
- Gukunda kurya
- Gutukura, kuma, cyangwa kwishimagura k'uruhu mu gace kavurirwamo
- Gutakaza umusatsi mu gace kavuwe
- Kugorwa no kumira iyo uvuje umunwa n'umuhogo
- Umutwe
Ingaruka nyinshi muri izi zigenda zigabanuka buhoro buhoro mu byumweru bike nyuma y’uko imiti irangiye. Vugana na muganga wawe nta guhishanya ku ngaruka zimwe na zimwe ushobora guhura nazo n’uko wabyifatamo.Niba hari ingaruka mbi zikomeye cyangwa wumva ikintu kidasanzwe, menyesha muganga wawe cyangwa ikigo kivura vuba. Mu bihe bikomeye, ni ngombwa kujya mu cyumba cy’ubuvuzi bwihutirwa (ETU) cy’ibitaro.
Ubutumwa bwo kujyana mu rugo
- EBRT ni uburyo busanzwe bwo kuvura kanseri, butababaza, kandi bukoreshwa cyane muri iki gihe.
- Ibi bikorwa n'itsinda ry'abaganga b'inzobere. Intego yabyo y'ibanze ni ugusenya uturemangingo twa kanseri gusa mu gihe kirinda uturemangingo tuzima.
- Ingaruka mbi zikunze kugaragara, ariko akenshi ziba iz'igihe gito. Ubwoko bw'ingaruka mbi zibaho biterwa n'agace k'umubiri uvurwa.
- Ni ingenzi cyane kuganira na muganga wawe mu buryo bweruye kandi mu kuri ku bijyanye n'uburyo bwo kuvura, ingaruka mbi, cyangwa ubwoba cyangwa impungenge ushobora kuba ufite.
