Lub luag haujlwm ntau yam ntawm Mis Biopsy koob nyob rau hauv Lub Sij Hawm Ntawm Cov Tshuaj Kho Mob

https://www.mayoclinic.org/tests-procedures/breast-biopsy/about/pac-20384812

Kev lig kev cai, lub luag haujlwm ib leeg ntawm lub mis biopsy koob yog "tshem cov ntaub so ntswg los txiav txim siab benignancy lossis malignancy." Txawm li cas los xij, nrog rau qhov tshwm sim ntawm cov tshuaj precision, qhov ntsuas me me no tau hla nws lub luag haujlwm raws li kev kuaj mob.cuab yeej,Piv txwv tias ua haujlwm tseem ceeb hauv kev saib xyuas kev kho mob, molecular profiling, thiab txawm tias kev kho mob hauv zos.

I. Tus Scout of Treatment Response: Dynamic Monitoring and Efficacy Assessment

Rau cov neeg mob qog nqaij hlav cancer mis uas tau txais kev kho mob Neoadjuvant Chemotherapy (NACT), qog cov lus teb rau cov tshuaj yog qhov tseem ceeb hauv kev txiav txim siab txog cov tswv yim kho mob tom ntej. Yav dhau los, cov kws kho mob tsuas yog tso siab rau txoj kev tsis ncaj ncees xws li palpation lossis imaging (piv txwv li, ultrasound, MRI) los ntsuas qhov hloov pauv ntawm cov qog loj. Cov txheej txheem no raug kev txom nyem los ntawm qhov kev ncua qeeb thiab tsis tuaj yeem sib txawv ntawm cov qog nqaij hlav thiab cov nqaij mos fibrotic.

Niaj hnub no, lub mis biopsy koob ua haujlwm raws li "scout." Ib nrab ntawm NACT (feem ntau tom qab 2nd lossis 3rd voj voog) los yog thaum nws xaus, cov kws kho mob ua ib tug rov biopsy ntawm thawj qhov txhab. Pathological tsom xam ntawm cov ntaub so ntswg tau tso cai rau:

1. Txiav txim siab Pathological Complete Response (pCR):​ Yog tias tsis muaj cov qog nqaij hlav qog noj ntshav tau kuaj pom, tus neeg mob yuav tsum tau ua tiav pCR, qhia tau tias muaj kev mob tshwm sim zoo thiab muaj peev xwm tso cai rau de- nce lossis tshem tawm ntawm kev phais tom ntej lossis kev kho hluav taws xob.
2. Txheeb xyuas cov txheej txheem tiv thaiv:Yog tias cov qog hlwb tseem ua haujlwm, kev sib txuas caj ces tuaj yeem txheeb xyuas qhov chaw hloov pauv tshiab, coj kev hloov mus rau lwm txoj kev khomob lossis kev kho mob sib xyaw ua ke.
3. Ntsuam xyuas Immune Microenvironment:​ Kev kuaj ntshav biopsy ua rau kev tsom xam ntawm qog-Infiltrating Lymphocytes (TILs) kom muaj nuj nqis thiab phenotype, kwv yees qhov ua tau zoo ntawm cov tshuaj tiv thaiv kab mob tiv thaiv kab mob.

Qhov "rov ua dua biopsy" lub tswv yim ua kom ntseeg tau tias kev kho mob tsis yog "ib- txoj kev" tab sis txoj kev hloov pauv hloov tau raws li qhov tseeb - lub sijhawm tawm tswv yim, ua kom paub tseeb ntawm tus kheej, "tsim- ua" txoj kev kho.

II. Tus Cartographer ntawm Molecular Landscapes: Los ntawm Morphology mus rau Genomics

Lub ntsiab lus ntawm precision tshuaj yog nyob rau hauv kev qhia molecular subtyping ntawm cov qog. Txawm hais tias me me, cov ntaub so ntswg kuaj tau los ntawm cov koob tshuaj biopsy muaj ntau cov ntaub ntawv lom neeg. Kev siv siab - dhau ntawm cov thev naus laus zis sequencing, peb tuaj yeem rho DNA thiab RNA los ntawm cov qauv no rau tag nrho -exome sequencing thiab transcriptomic tsom xam, yog li ua daim ntawv cog lus "molecular portrait."

1. Discovery of Driver Genes:Txheeb xyuas qhov kev hloov pauv hauv cov noob tseem ceeb xws liPIB 3CA, ESR1, thiabHER 2pab txheeb xyuas cov neeg mob zoo tshaj plaws rau kev kho mob. Piv txwv li, PARP inhibitors yuav yog qhov kev xaiv zoo tshaj rau cov neeg mob harboringPAB 1/2kev hloov pauv.
2. Unmasking Heterogeneity:Cov cheeb tsam sib txawv hauv tib lub qog tuaj yeem muaj qhov sib txawv ntawm qhov sib txawv. Ntau -qhov chaw, ntau-cov tub ntxhais biopsies tuaj yeem nthuav tawm qhov "spatial heterogeneity," pab cov kws kho mob nkag siab tias vim li cas qee thaj chaw muaj kev cuam tshuam rau kev kho mob thaum lwm tus muaj kev tawm tsam.
3. Ua kom tiav Liquid Biopsy:Thaum kev kuaj qog DNA (ctDNA) yog qhov yooj yim, cov ntaub so ntswg biopsy tseem yog tus qauv kub. Nws muab cov ntaub ntawv ntxaws ntxaws ntawm cov qauv sib txawv xws li chromosomal rearrangements thiab luam cov lej hloov pauv -cov ntaub ntawv uas ctDNA feem ntau ua tsis tau tiav.

Nws tuaj yeem hais tau tias txhua cov ntaub so ntswg uas tau muab rho tawm los ntawm rab koob biopsy ua haujlwm ua lub thawv ntawv txhawm rau qhib lub qog cov cai.

III. Micro-Scalpel ntawm Kev Kho Mob Hauv Zos: Kev kuaj kab mob thiab kev kho mob

Kev taw qhia ntawm Nqus Tsev-Assisted Breast Biopsy (VABB) systems tau tso cai rau cov koob tshuaj biopsy nrog cov yam ntxwv kho mob. Rau cov qog me dua 2 cm uas yog qhov tsis txaus ntseeg rau benignity (xws li, fibroadenomas), cov kws kho mob tuaj yeem siv 7G lossis 9G rotating cutters raws li kev taw qhia ultrasound kom ua tiav kev txiav txim siab. Piv nrog rau cov kev phais qhib ib txwm, qhov "qhov kev txiav tawm tsawg kawg nkaus" muaj qhov zoo: qhov caws pliav tsawg heev (tsuas yog 2-3 hli), rov qab sai, thiab tsis tas yuav tsum muaj cov sutures.

Tsis tas li ntawd, cov koob tshuaj biopsy tab tom tshawb nrhiav cov kev kho tshiab tshiab, xws li:

• Kev Kho Mob Ablative:​ Kev xa xov tooj cua, microwave, lossis cryoprobes los ntawm lub koob tshuaj biopsy channel kom ua tiav hauv -situ qog inactivation.
• Kev xa tshuaj hauv zos:Siv rab koob hollow los txhaj tshuaj chemotherapeutic agents, immunomodulators, los yog gene vectors ncaj qha mus rau hauv cov qog, yog li ua kom cov tshuaj hauv zos concentration thaum txo cov kab mob toxicity.

Xaus

Los ntawm qhov pib "ib-size- haum-tag nrho" txoj kev kuaj mob mus rau nws txoj haujlwm tam sim no raws li "scout," "cartographer," thiab "micro-}scalpel," txoj haujlwm ntawm rab koob ntawm lub mis tau dhau los ua qhov hloov pauv tseem ceeb. Nws tsis yog cov txheej txheem cais tawm lawm tab sis yog "multifunctional platform" kev koom ua ke thoob plaws tag nrho cov kev kuaj mob qog noj ntshav ntawm lub mis, kuaj mob, saib xyuas kev kho mob, thiab kev cuam tshuam hauv zos. Nyob rau hauv lub neej yav tom ntej, nrog kev koom ua ke ntawm nanotechnology thiab cov ntaub ntawv ntse, rab koob no yuav qhib tau ntau dua, txuas ntxiv coj tus kab mob ntawm lub mis mus rau lub neej yav tom ntej uas txhais los ntawm qhov tseeb dua, kev cuam tshuam tsawg, thiab tib neeg- kev saib xyuas centric.
