Peb coob leej ntau tus ntshai thaum peb hnov lo lus mob qog noj ntshav. Peb kuj ntshai heev rau kev kho mob hluav taws xob . Nws yog ib qho ib txwm xav tias, "Auj, qhov no puas yuav cuam tshuam rau cov khoom noj qab haus huv ntawm lub cev thiab?" Tab sis niaj hnub no thev naus laus zis tau nce qib heev. Niaj hnub no peb tab tom tham txog txoj kev npaj kho mob hluav taws xob tshwj xeeb uas tsom mus rau qhov mob qog noj ntshav thiab txo qhov kev puas tsuaj rau cov kab mob noj qab haus huv ib puag ncig. Ntawd yog 3D-CRT.
Qhov 3D-CRT no yog dab tsi?
Hais yooj yim xwb, 3D-CRT yog ib txoj kev siv tshuab siab heev uas siv los npaj Kev Kho Mob Hluav Taws Xob Sab Nraud (EBRT) rau mob qog noj ntshav. Nws tsis yog kev kho mob nws tus kheej, tab sis yog txoj kev npaj rau kev kho mob .
Xav txog koj mus rau tus kws txiav khaub ncaws kom txiav ib lub tiab. Nws ntsuas koj qhov ntsuas thiab txiav lub tiab kom haum koj zoo meej, puas yog? 3D-CRT zoo li ntawd. Ntawm no, cov kws kho mob hluav taws xob tau txais daim duab peb-seem (3D) ntawm koj lub qog nqaij hlav thiab cov kab mob noj qab haus huv nyob ib puag ncig nws.
Yuav kom tau txais daim duab 3D no, cov duab los ntawm kev kuaj mob xws li 'CT (Computed Tomography)' scan, ' MRI (Magnetic Resonance Imaging)' scan, lossis 'PET ( Positron Emission Tomography )' scan raug siv. Cov software computer tshwj xeeb tshuaj xyuas cov duab no thiab tsim 'daim ntawv qhia 3D' ntawm qhov loj me, cov duab, thiab qhov chaw ntawm tus mob qog noj ntshav.
Daim ntawv qhia 3D no tso cai rau cov teeb hluav taws xob kom raug tsom mus rau qhov mob qog noj ntshav, txo qhov kev puas tsuaj los ntawm cov hluav taws xob rau cov kab mob noj qab haus huv ib puag ncig xws li lub ntsws, lub plawv, thiab lub siab .
Cov kev siv ntawm 3D-CRT yog dab tsi?
Cov kws kho mob qog noj ntshav siv txoj kev npaj 3D-CRT no los kho ntau hom mob qog noj ntshav. Txoj kev no tseem ceeb heev rau cov xwm txheej uas phais tsis tau. Nws kuj muab kev kho mob hluav taws xob npaj tseg kom txo qhov mob qog noj ntshav ua ntej phais ('neoadjuvant therapy') lossis rhuav tshem cov hlwb qog noj ntshav uas tseem tshuav tom qab phais ('adjuvant therapy').
Hauv qab no yog qee hom mob qog noj ntshav uas siv 3D-CRT feem ntau.
| Hom Mob Cancer | Xav paub ntxiv |
|---|---|
| Mob qog nqaij hlav ntawm qhov quav | Txhawm rau npaj kev kho mob nrog lossis tsis muaj kev phais. |
| Mob qog nqaij hlav ntawm lub qhov quav | Nws feem ntau yog siv los ua kom lub qog me me ua ntej phais. |
| Mob qog noj ntshav hauv lub mis | Hauv cov xwm txheej uas muaj kev pheej hmoo ntawm kev rov tshwm sim ntau tom qab kev kho mob. |
| Mob qog nqaij hlav ntawm txoj hnyuv | Thaum nws kis mus rau lub ntsws lossis lub siab lawm ces phais tsis tau. |
| Mob qog noj ntshav hauv taub hau thiab caj dab | Piv txwv li: Mob qog nqaij hlav Laryngeal thiab Nasopharyngeal. |
| Mob qog noj ntshav ntawm lub cev zom zaub mov | Piv txwv li: mob qog nqaij hlav ntawm lub zais zis thiab cov hlab ntsha hauv lub cev. |
| Mob qog nqaij hlav prostate | Siv rau hauv ob qho tib si thaum ntxov thiab mob hnyav. |
| Mob qog nqaij hlav ntsws | Ua ib qho kev kho mob tseem ceeb thaum phais tsis tau. |
| Lwm yam mob qog noj ntshav | Nws kuj tseem siv rau lwm yam mob qog noj ntshav xws li 'Ewing sarcoma', 'Vulvar cancer', 'Wilms tumor'. |
3D-CRT siv li cas rau hauv kev npaj kho mob?
Koj pab neeg kho mob yuav coj koj mus dhau cov txheej txheem npaj 3D-CRT no ib kauj ruam zuj zus.
1. Tsim Daim Ntawv Qhia 3D
Ua ntej, zoo li peb tau tham ua ntej lawm, cov duab los ntawm koj cov CT thiab MRI scans raug thaij thiab ib qho kev pab cuam hauv computer tsim ib daim ntawv qhia 3D ntawm lub qog. Daim ntawv qhia no raug pub rau hauv lub tshuab uas xa cov hluav taws xob (lub 'Linear Accelerator').
2. Cov txheej txheem simulation
Qhov no zoo li kev xyaum ua yeeb yam. Koj yuav raug yuam kom pw saum lub rooj kho mob thiab muab koj tso rau hauv qhov chaw zoo li koj yuav tau txais kev kho mob hluav taws xob. Thaum lub sijhawm no, daim ntawv qhia 3D yuav raug siv los txiav txim siab qhov chaw thiab lub kaum sab xis ntawm cov teeb hluav taws xob.
3. Siv cov cim tawv nqaij
Thaum lub sijhawm simulation, pab pawg kho mob yuav muab ntau lub cim me me, zoo li lub cim dot rau ntawm koj daim tawv nqaij. Cov no feem ntau yog cov cim me me ('tattoos') uas zoo li cov tattoos tas mus li . Tsis txhob ntshai thaum koj pom cov no. Cov no tau muab tso rau kom thaum lub sijhawm kho mob txhua zaus, lub teeb ci ntsa iab yuav raug taw qhia rau qhov chaw uas cov hlwb qog nqaij hlav nyob, yam tsis txav txawm tias ib millimeter. Cov cim no yuav pab koj khaws koj lub cev rau tib qho chaw thaum lub sijhawm kho mob txhua zaus.
3D-CRT puas ua rau muaj kev phiv?
Qhov tseem ceeb uas yuav tsum nkag siab ntawm no yog tias 3D-CRT yog ib txoj kev npaj , tsis yog kev kho mob. Yog li ntawd, tsis muaj cov kev phiv ncaj qha los ntawm cov txheej txheem npaj 3D-CRT.
Txawm li cas los xij, kev kho mob hluav taws xob raws li txoj kev npaj ntawd tuaj yeem ua rau muaj qee qhov kev phiv. Txawm hais tias 3D-CRT txo qhov kev puas tsuaj rau cov nqaij noj qab haus huv, qee qhov kev puas tsuaj tseem ua tau. Cov kev phiv uas tshwm sim nyob ntawm thaj chaw ntawm lub cev uas tau kho.
| Cov teebmeem sab | Ib qho lus piav qhia yooj yim |
|---|---|
| Kev qaug zog | Ib qho mob uas feem ntau tshwm sim thaum lub cev tawm tsam cov hlwb qog noj ntshav thiab yog vim kev kho mob. |
| Xeev siab thiab ntuav | Qhov no tuaj yeem tshwm sim tshwj xeeb tshaj yog thaum kho thaj tsam plab. |
| Kev ntshaw noj mov | Kev kho mob yuav ua rau muaj kev hloov pauv ntawm saj. |
| Mob taub hau | Tej zaum yuav tshwm sim thaum kho thaj chaw taub hau. |
| Kev hloov pauv ntawm daim tawv nqaij | Liab, qhuav, khaus, lossis mob hauv thaj chaw kho mob. |
| Mob zis tsis taus | Nws tuaj yeem tshwm sim thaum kho qhov mob plab qis lossis thaj chaw pelvic. |
| Mob raws plab | Tej zaum yuav tshwm sim thaum kho thaj chaw plab hnyuv. |
Cov txiaj ntsig thiab thev naus laus zis niaj hnub ntawm 3D-CRTs
Qhov zoo tshaj plaws ntawm txoj kev 3D-CRT yog tias nws tsom mus rau qhov mob qog nqaij hlav kom meej heev thiab txo qhov kev puas tsuaj rau cov nqaij noj qab haus huv ib puag ncig.
Txawm li cas los xij, niaj hnub no muaj cov txheej txheem npaj kho mob hluav taws xob zoo dua li 3D-CRT. Ib qho ntawm lawv yog 'Kev Kho Mob Hluav Taws Xob Uas Hloov Kho Qhov Hnyav (IMRT)'.
IMRT siv ntau lub teeb me me (beamlets) es tsis txhob siv ib lub teeb loj. Qhov ci ntawm lub teeb kuj hloov tau. Zoo li pleev xim rau ib daim duab nrog cov xim me me sib txawv, tsis yog ib xim xwb. Qhov no tso cai rau IMRT xa cov hluav taws xob uas phim zoo dua rau cov duab ntawm lub qog. Qee qhov kev tshawb fawb qhia tias IMRT yuav muaj cov kev mob tshwm sim tsawg dua.
Tab sis seb 3D-CRT, IMRT, lossis lwm txoj kev puas zoo tshaj plaws rau koj yog txiav txim siab los ntawm koj pab neeg kho mob qog noj ntshav. Nws nyob ntawm ntau yam, suav nrog hom, qhov chaw, thiab qhov loj ntawm koj tus mob qog noj ntshav.
Yog tias koj tau txais kev kho mob hluav taws xob, tsis txhob ntshai nug koj tus kws kho mob lossis pab pawg kho mob txog cov txheej txheem. Nws yuav yog qhov kev nplij siab zoo rau koj kom paub txhua yam meej.
