Ambiri a ife timaopa tikamva mawu akuti khansa. Timakhalanso ndi mantha aakulu a chithandizo cha radiation . Ndizachibadwa kuganiza kuti, "O, kodi izi zingakhudzenso ziwalo zathanzi za thupi?" Koma ukadaulo wamakono ndi wapamwamba kwambiri. Lero tikulankhula za dongosolo lapadera la chithandizo cha radiation lomwe limayang'ana bwino chotupa cha khansa ndikuchepetsa kuwonongeka kwa ziwalo zathanzi zozungulira. Imeneyo ndi 3D-CRT.
Kodi 3D-CRT iyi ndi chiyani?
Mwachidule, 3D-CRT ndi njira yapamwamba kwambiri yomwe imagwiritsidwa ntchito pokonzekera chithandizo cha khansa cha External Beam Radiation Therapy (EBRT). Si chithandizo chokhacho, koma dongosolo la chithandizocho .
Tangoganizani mupita kwa katswiri wosoka kuti akakupangireni diresi. Iye amakutengerani muyeso weniweni ndikukukonzerani diresi kuti likugwirizaneni bwino, sichoncho? 3D-CRT ili choncho. Apa, madokotala a khansa ya radiation amawona chotupa chanu cha khansa ndi ziwalo zathanzi zomwe zili mkati mwake.
Kuti mupeze mawonekedwe a 3D awa, zithunzi kuchokera ku mayeso ozindikira matenda monga `CT (Computed Tomography)` scan, ` MRI (Magnetic Resonance Imaging)` scan, kapena `PET ( Positron Emission Tomography )` scan zimagwiritsidwa ntchito. Mapulogalamu apakompyuta apadera amasanthula zithunzizi ndikupanga `3D map` ya kukula, mawonekedwe, ndi malo enieni a khansa.
Mapu awa a 3D amalola kuti kuwala kwa radiation kulowetsedwe molondola ku chotupa cha khansa, zomwe zimachepetsa kwambiri kuwonongeka komwe kumachitika chifukwa cha kuwala kwa radiation ku ziwalo zathanzi zozungulira monga mapapo, mtima, ndi chiwindi .
Kodi ntchito za 3D-CRT ndi ziti?
Madokotala a khansa amagwiritsa ntchito njira yokonzekera ya 3D-CRT pochiza mitundu yosiyanasiyana ya khansa. Njirayi ndi yofunika kwambiri makamaka pamene opaleshoni siingatheke. Imaperekanso chithandizo cha radiation chokonzedwa kuti chichepetse chotupacho musanachite opaleshoni (`neoadjuvant therapy`) kapena kuwononga maselo ena onse a khansa pambuyo pa opaleshoni (`adjuvant therapy`).
Pansipa pali mitundu yodziwika bwino ya khansa yomwe 3D-CRT imagwiritsidwa ntchito.
| Mtundu wa Khansa | Zambiri |
|---|---|
| Khansa ya m'makoswe | Kukonzekera chithandizo ndi opaleshoni kapena popanda opaleshoni. |
| Khansa ya m'matumbo | Kawirikawiri amagwiritsidwa ntchito kuchepetsa chotupacho musanachite opaleshoni. |
| Khansa ya m'mawere | Ngati chiopsezo chobwereranso chikadzabweranso pambuyo pa chithandizo, chiopsezocho chimakhala chachikulu. |
| Khansa ya m'matumbo | Ngati yafalikira m'mapapo kapena m'chiwindi ndipo opaleshoni siingatheke. |
| Khansa ya mutu ndi khosi | Mwachitsanzo: Khansa ya m'khosi ndi m'mphuno. |
| Khansa ya m'mimba | Mwachitsanzo: Khansa ya ndulu ndi ndulu. |
| Khansa ya prostate | Amagwiritsidwa ntchito m'matenda oyamba komanso opitilira. |
| Khansa ya m'mapapo | Monga chithandizo chachikulu pamene opaleshoni sikutheka. |
| Khansa zina | Amagwiritsidwanso ntchito pa khansa zina monga `Ewing sarcoma`, `Vulvar cancer`, `Wilms tumor`. |
Kodi 3D-CRT imagwiritsidwa ntchito bwanji pokonzekera chithandizo?
Gulu lanu lachipatala lidzakutsogolerani mu ndondomeko yokonzekera ya 3D-CRT pang'onopang'ono.
1. Kupanga Mapu a 3D
Choyamba, monga tafotokozera kale, zithunzi kuchokera ku CT ndi MRI scan yanu zimatengedwa ndipo pulogalamu ya pakompyuta imapanga mapu a 3D a chotupacho. Mapu awa amalowetsedwa mu makina omwe amapereka kuwala (`Linear Accelerator`).
2. Njira yoyeserera
Izi zili ngati masewero olimbitsa thupi. Mudzagonekedwa patebulo la chithandizo ndipo mudzaikidwa ngati momwe mukulandirira chithandizo cha radiation. Pakadali pano, mapu a 3D adzagwiritsidwa ntchito kudziwa malo enieni ndi ngodya ya radiation.
3. Kuyika zizindikiro za khungu
Pa nthawi yoyeserera, gulu lachipatala lidzaika zizindikiro zingapo zazing'ono kwambiri, zonga madontho pakhungu lanu. Izi nthawi zambiri zimakhala zizindikiro zazing'ono ('ma tattoo') zomwe zimawoneka ngati ma tattoo okhazikika . Musachite mantha mukaziona. Izi zimayikidwa kuti panthawi ya chithandizo chilichonse, kuwala kwa radiation kutsogozedwe komwe kuli maselo a khansa, osasuntha ngakhale milimita imodzi. Zizindikirozi zidzakuthandizani kuti thupi lanu likhale pamalo omwewo panthawi ya chithandizo chilichonse.
Kodi 3D-CRT imayambitsa zotsatirapo zoyipa?
Chofunika kumvetsetsa apa ndichakuti 3D-CRT ndi njira yokonzekera , osati chithandizo. Chifukwa chake, palibe zotsatirapo zoyipa zomwe zimachitika chifukwa cha njira yokonzekera 3D-CRT.
Komabe, chithandizo cha radiation choperekedwa motsatira dongosolo limenelo chingayambitse zotsatirapo zina. Ngakhale kuti 3D-CRT imachepetsa kwambiri kuwonongeka kwa minofu yathanzi, kuwonongeka kwina n'kotheka. Zotsatirapo zomwe zimachitika zimadalira dera la thupi lomwe likuchiritsidwa.
| Zotsatira Zam'mbali | Kufotokozera kosavuta |
|---|---|
| Kutopa | Vuto lofala lomwe limachitika pamene thupi likulimbana ndi maselo a khansa komanso chifukwa cha chithandizo. |
| Kusanza ndi kusanza | Izi zitha kuchitika makamaka pochiza dera la m'mimba. |
| Chilakolako cha chakudya | Chithandizo chingayambitse kusintha kwa kukoma. |
| Mutu | Zitha kuchitika pochiza mutu. |
| Kusintha kwa khungu | Kufiira, kuuma, kuyabwa, kapena kupweteka pamalo ochiritsira. |
| Dysuria | Zitha kuchitika pochiza m'mimba kapena m'chiuno. |
| Kutsegula m'mimba | Zitha kuchitika pochiza matumbo. |
Ubwino ndi ukadaulo wamakono wa 3D-CRTs
Ubwino waukulu wa njira ya 3D-CRT ndikuti imayang'ana bwino chotupacho ndipo imachepetsa kuwonongeka kwa minofu yathanzi yozungulira.
Komabe, masiku ano pali njira zamakono zokonzekera chithandizo cha radiation kuposa 3D-CRT. Imodzi mwa njira zimenezi ndi `Intensity-Modulated Radiation Therapy (IMRT)`.
IMRT imagwiritsa ntchito mipiringidzo yaying'ono yambiri (mipiringidzo) m'malo mwa mipiringidzo imodzi yayikulu. Mphamvu ya mipiringidzoyo ingasinthidwenso. Zili ngati kujambula chithunzi ndi mipiringidzo yaying'ono yosiyanasiyana ya utoto, m'malo mwa mtundu umodzi. Izi zimathandiza IMRT kupereka kuwala komwe kumagwirizana bwino ndi mawonekedwe ovuta a chotupacho. Kafukufuku wina akusonyeza kuti IMRT ikhoza kukhala ndi zotsatirapo zochepa.
Koma ngati 3D-CRT, IMRT, kapena njira ina ndi yabwino kwa inu zimatsimikiziridwa ndi gulu lanu lochiza khansa. Zimatengera zinthu zambiri, kuphatikizapo mtundu, malo, ndi kukula kwa khansa yanu.
Ngati mwapatsidwa chithandizo cha radiation, musaope kufunsa dokotala wanu kapena gulu lachipatala za njira imeneyi. Zidzakhala zosangalatsa kwambiri kudziwa zonse bwino.
Uthenga Wopita Nawo Kunyumba
- 3D-CRT si mankhwala a radiation, koma njira yolondola kwambiri komanso yokonzekera zinthu zitatu (3D).
- Izi zimalimbana ndi chotupa cha khansa ndipo zimachepetsa kuwonongeka komwe kumachitika chifukwa cha kuwala kwa dzuwa ku ziwalo zathanzi zozungulira.
- Kukonzekera kumeneku kumaphatikizapo kusanthula zithunzi monga CT ndi MRI, ndikugwiritsa ntchito zizindikiro zazing'ono pakhungu kuti zitsimikizire kulondola kwa chithandizocho.
- Zotsatirapo zake zimachitika chifukwa cha chithandizo cha radiation chomwe chaperekedwa, osati chifukwa cha njira yomwe yakonzedwa. Zimasiyana malinga ndi dera la thupi lomwe likuchiritsidwa.
- Kambiranani ndi dokotala wanu za chithandizo chomwe chili chabwino kwa inu. Musamaope kufunsa mafunso aliwonse.
