Kev kos duab thiab kho tus nqi ntawm Brachytherapy koob hauv kev kho mob qog noj ntshav

Core tswvyim:Hauv kev kho mob qog noj ntshav hauv tsev menyuam, cov koob tshuaj brachytherapy xa cov khoom siv hluav taws xob sib sib zog nqus mus rau hauv cov qog nqaij hlav ntawm interstitial implantation. Qhov no yog cov qauv tseem ceeb rau kev txhim kho kev tswj hwm hauv zos thiab txo qhov kev pheej hmoo ntawm kev rov tshwm sim.

Thaum tus neeg mob txoj kev kho mob qog noj ntshav, kev siv cov koob tshuaj brachytherapy qhia txog qhov tsis muaj txiaj ntsig kho mob, tshwj xeeb hauv gynecological oncology, tshwj xeeb tshaj yog rau mob qog noj ntshav. Raws li ib qho kev hem thawj loj rau poj niam txoj kev noj qab haus huv thoob ntiaj teb, mob qog noj ntshav hauv tsev kho mob tso siab rau kev siv xov tooj cua ua lub hauv paus ntawm kev kho mob. Thaum ib txwm siv sab nrauv Beam Radiation Therapy (EBRT) tawm tsam kom xa cov koob tshuaj txaus txaus rau thawj qhov ncauj tsev menyuam, koob tshuaj brachytherapy daws qhov teeb meem no.

Cervical cancer brachytherapy feem ntau yog ua tiav nyob rau hauv ob theem: thawj zaug, EBRT raug tswj xyuas kom txo cov qog ntim; Tom qab ntawd, intracavitary brachytherapy-feem ntau hu ua "afterloading"- tau ua. Thaum lub sij hawm no, nyob rau hauv cov tshuaj loog, tus kws kho mob muab ib los yog ntau tshaj tshwj xeeb brachytherapy koob los ntawm ib tug qhov chaw mos applicator, precisely lub hom phiaj ntawm lub ncauj tsev menyuam qog thiab nws infiltrative margins. Cov khoom siv (piv txwv li, stainless hlau), ntev, thiab txoj kab uas hla (feem ntau zoo gauges, 18-21G) ntawm cov koob no tau raug xaiv los xyuas kom meej txaus rigidity rau cov ntaub so ntswg nkag mus rau lub minimizing raug mob.

Thaum muab tso rau, cov koob no tsim ib qho peb - qhov "network of lem." Ua raws li cov phiaj xwm ua ntej- kev ua haujlwm ua haujlwm, tus kws kho mob siv cov chaw taws teeb tom qab thauj khoom los tsav lub siab - cov khoom siv hluav taws xob hluav taws xob (xws li Iridium-192) ua ntu zus mus rau hauv txoj haujlwm tau npaj ua ntej raws li cov kab no. Lub sij hawm nyob ntawm txhua txoj hauj lwm dictates cov hluav taws xob faib tshuaj rau thaj tsam ntawd. Tag nrho cov txheej txheem zoo ib yam li lub microscopic, precision "delayed detonation"; los ntawm kev kho qhov chaw ntawm txoj kev thiab lub sijhawm, cov kws kho mob tuaj yeem sculpt lub siab - cheeb tsam koob uas ua kom nruj rau cov qog cov duab-txawm yog "pear-zoo li" lossis "dumbbell-shaped."

Tus nqi kho mob ntawm cov cuab yeej no yog qhov tob. Nws concentrates siab - koob tshuaj hluav taws xob nyob rau hauv lub ncauj tsev menyuam thiab thaj chaw parametrial thaum nthuav tawm lub zais zis sab hauv thiab tom qab lub qhov quav kom tsawg kawg nkaus. Cov kev tshawb fawb qhia tias Duab-Guided Adaptive Brachytherapy (IGABT) tuaj yeem txhim kho cov kev tswj xyuas hauv zos rau kev mob khees xaws ncauj tsev menyuam mus rau ntau dua 90%, thaum txo qis qhov tshwm sim ntawm hluav taws xob loj heev -induced cystitis thiab proctitis. Rau ntau tus neeg mob tsis tuaj yeem ua haujlwm tau zoo hauv zos, qhov no sawv cev rau qhov kev cia siab kawg rau kev kho.
