Raws li "Trojan nees" uas xa hluav taws xob hluav taws xob ncaj qha mus rau hauv cov qog, koob brachytherapy tau nthuav dav lawv cov kev siv tshuaj kho mob los ntawm cov qog gynecological mus rau ntau qhov chaw xws li prostate, mis, taub hau thiab caj dab thiab mob qog noj ntshav, dhau los ua riam phom precision tseem ceeb hauv kev kho mob qog noj ntshav niaj hnub no. Los ntawm kev siv thev naus laus zis tsis tu ncua, cov tuam txhab tsim cov koob tshuaj brachytherapy kom meej meej hais txog ntau yam xwm txheej kho mob xws li kev kho mob radical curative mus rau palliative symptom nyem nyem, zoo heev enriching hluav taws xob oncologists tactical xaiv thiab profoundly reshaping toj roob hauv pes kho mob ntawm ntau yam qog noj ntshav.

Hauv kev kho mob qog noj ntshav prostate, koob tshuaj brachytherapy ua lub luag haujlwm tseem ceeb hauv kev kho radical thiab kev ua haujlwm khaws cia. Rau kev mob qog nqaij hlav prostate thaum ntxov, kev cog qoob loo mus tas li (piv txwv li, Iodine-125) tuaj yeem ua haujlwm ib leeg ib leeg. Raws li kev taw qhia ntawm lub sijhawm ntawm ultrasound, ntau cov koob zoo (feem ntau nyob ib ncig ntawm 18G) yog qhov tseeb perineally ntxig rau hauv cov qog nqaij hlav ntawm cov qauv, nrog cov noob xaum hluav taws xob faib rau hauv raws li tau npaj tseg. Cov hluav taws xob txuas ntxiv tsom mus rau cov qog, thaum lub cev muaj kev pheej hmoo xws li lub qhov quav thiab lub zais zis tau txais cov koob tshuaj tsawg vim yog cov yam ntxwv ntawm kev poob qis, ua rau cov neeg mob tso zis ntau ntxiv thiab kev ua haujlwm ntawm kev sib deev. Rau cov neeg mob nruab nrab- thiab muaj kev pheej hmoo siab, High-Dose-Rate (HDR) tom qab-loading therapy ua ib qho kev txhawb nqa rau sab nraud beam radiotherapy. Cov khoom siv hluav taws xob ua haujlwm siab (xws li, Iridium-192) raug xa mus rau hauv prostate los ntawm cov koob interstitial ib ntus rau fractionated high-dose irradiation, ntxiv kev txhim kho hauv zos tswj cov nqi.

Hauv gynecological oncology, tshwj xeeb tshaj yog rau cov mob qog noj ntshav hauv zos, brachytherapy yog lub hauv paus ntawm radical radiotherapy. Ib txwm siv cov tshuaj intracavitary (piv txwv li, triple-channel tubes) feem ntau tso tawm cov koob tshuaj zoo tshaj plaws rau eccentric, cov qog loj lossis cov uas muaj cov ntaub so ntswg parametrial. Nyob rau hauv cov xwm txheej zoo li no, interstitial brachytherapy ua tiav cov koob tshuaj sib luag zoo heev los ntawm kev tso ncaj qha rau ntau cov koob tshuaj rau hauv cov qog. Cov koob tshuaj kho mob pab kom cov cheeb tsam uas tau koob tshuaj kom meej meej npog txhua lub ces kaum ntawm cov qog nqaij hlav tsis tu ncua thaum tiv thaiv cov ntaub so ntswg zoo li lub zais zis thiab qhov quav, txhawb kev tswj hwm hauv zos thiab txo cov teeb meem.

Rau cov neeg mob uas muaj mob qog noj ntshav thaum ntxov tom qab kev phais lub mis, Accelerated Partial Breast Irradiation (APBI) muaj kev xaiv tshiab. Ib lub zais pa catheter lossis ntau lub koob txhaj tshuaj tau muab tso rau ib ncig ntawm lub qog resection kab noj hniav intraoperatively, ua kom meej meej ntawm kev siv tshuaj tua hluav taws xob sai sai tom qab kev phais. Cov txheej txheem no nqaim cov irradiation teb los ntawm tag nrho lub mis mus rau lub qog txaj periphery thiab shortens kev kho mob lub sij hawm los ntawm lub lis piam mus rau hnub, xa superior cosmetic cov txiaj ntsim thiab zoo ntawm lub neej thaum lub sij hawm kom paub tseeb kev kho mob.

Cov koob tshuaj Brachytherapy kuj qhia tau tias muaj kev ua tau zoo hauv cov qog nqaij hlav taub hau thiab caj dab, cov nqaij mos sarcomas, mob qog noj ntshav thiab lwm yam mob. Rau cov kab mob tom qab phais tas, rov tshwm sim dua lossis tsis tuaj yeem ua haujlwm, cov duab qhia kev ntxig rau cov koob kho mob rau hauv cov qog nqaij hlav rau cov kab mob sib kis tau muab cov koob tshuaj hauv zos siab heev rau qhov mob thaum tiv thaiv ib puag ncig cov hlab ntsha tseem ceeb, cov hlab ntsha thiab pob txha. Rau cov qog nqaij hlav ntawm daim tawv nqaij xws li basal-cell carcinoma, tshwj xeeb nto applicators los yog interstitial koob rau kev sib cuag los yog kev kho mob interstitial ua tiav cov txiaj ntsig zoo nkauj zoo nkauj thiab kho tus nqi.

Tsis tas li ntawd, cov koob tshuaj brachytherapy muaj qhov tshwj xeeb hauv kev kho mob palliative. Rau qhov mob hnyav tshwm sim los ntawm cov pob txha mob qog noj ntshav, lossis cov kab mob metastatic ua rau cov tsos mob tshwm sim hauv qhov chaw tseem ceeb xws li vertebrae thiab pelvis, sab hauv irradiation los ntawm cov noob cog qoob loo tau zoo txo ​​qhov mob, tswj cov qog hauv zos thiab txhim kho cov neeg mob lub neej zoo.

Yog li ntawd, cov khoom lag luam los ntawm cov koob tshuaj brachytherapy tseem ceeb muab cov hluav taws xob oncology hauv zej zog nrog kev hloov pauv tau yooj yim thiab meej "cov cuab yeej siv tshuaj hauv zos". Cov cuab yeej zoo li no txhais cov txiaj ntsig ntawm lub cev dosimetry rau hauv cov txiaj ntsig kho mob rau cov qog ntawm cov chaw sib txawv thiab theem. Spanning ntau theem ntawm kev kho mob qog noj ntshav, koob tshuaj brachytherapy yog siv los kho cov qog nqaij hlav thaum ntxov, txo cov tsos mob ntawm theem siab, khaws cia cov haujlwm tseem ceeb hauv nruab nrog cev thiab txhim kho cov neeg mob lub neej zoo. Los ntawm tsis tu ncua optimizing koob rigidity, sharpness, specification ntau haiv neeg thiab compatibility nrog cov duab navigation thiab 3D-printed templates, manufacturers tau nthuav dav daim ntawv thov ciam teb ntawm no technology, tig brachytherapy koob mus rau ib tug zuj zus ntse thiab meej "invisible scalpel" tiv thaiv qog nyob rau hauv lub era ntawm precision tshuaj.
