Lub raum cell carcinoma qhia txog pathology

Renal Cell Carcinoma Pathology Outlines: Phau Ntawv Qhia Txog Kev Kho MobRenal Cell Carcinoma (RCC) yog ib yam kab mob nyuaj, thiab kev nkag siab txog nws cov kab mob yog qhov tseem ceeb rau kev kuaj mob zoo thiab kev kho mob. Phau ntawv qhia no muab cov ntsiab lus dav dav ntawm Lub raum cell carcinoma qhia txog pathology, suav nrog cov yam ntxwv tseem ceeb histological, subtypes, thiab cov txheej txheem kuaj mob.

Histological nta ntawm lub raum Cell Carcinoma

Clear Cell Renal Cell Carcinoma

Cov subtype feem ntau ntawm RCC, ntshiab cell carcinoma, yog tus cwj pwm los ntawm nws cov cytoplasm ntshiab. Qhov no yog vim qhov sib txuam ntawm lipids thiab glycogen hauv cov hlwb. Microscopically, koj yuav pom ntau lub hlwb nyob hauv zes lossis papillae, nrog cov nuclei tseem ceeb. Lub xub ntiag ntawm eosinophilic granular cytoplasm kuj tshwm sim. Kev txheeb xyuas qhov tseeb yog nyob ntawm kev kuaj mob histological, feem ntau ua tiav los ntawm immunohistochemistry kom paub meej tias kev kuaj mob. Kev tshawb nrhiav ntxiv tuaj yeem suav nrog kev kuaj caj ces txhawm rau txheeb xyuas qhov muaj peev xwm hloov pauv, qhia txog cov tswv yim kho tus kheej.

Papillary Renal Cell Carcinoma

Papillary RCC yog lwm yam tseem ceeb subtype txawv los ntawm nws cov papillary loj hlob qauv. Cells zoo li yuav tsum tau npaj nyob rau hauv txawv papillae, feem ntau nthuav tawm pseudostratification. Nuclear atypia txawv nyob ntawm qib, nrog cov qib siab dua qhia qhov txawv txav tseem ceeb. Immunohistochemical staining tuaj yeem pab cais nws los ntawm lwm yam RCC subtypes thiab urothelial carcinoma. Rau kev nkag siab tob, tshawb nrhiav cov kab mob tshwj xeeb thiab cov peev txheej hauv online los ntawm cov tsev muaj npe nrov xws li National Cancer Institute (NCI) tuaj yeem muaj txiaj ntsig.

Chromophobe Raum Cell Carcinoma

Chromophobe RCC, raws li lub npe qhia, yog tus cwj pwm los ntawm cov hlwb nrog daj ntseg, ntshiab cytoplasm thiab txawv cell ciam teb. Lub nuclei feem ntau yog puag ncig thiab nyob hauv nruab nrab. Qhov no subtype feem ntau qhia tau hais tias tus yam ntxwv perinuclear halo. Qhov txawv morphology no feem ntau txaus rau kev kuaj mob, txawm hais tias immunohistochemistry tuaj yeem pab tau kom paub meej qhov kev kuaj mob thiab tsis suav nrog lwm cov qog. Cov tswv yim zoo tshaj plaws xws li suav tomography (CT) scans kuj tau siv los txheeb xyuas qhov cuam tshuam ntawm qog nqaij hlav.

Lwm yam subtypes ntawm lub raum Cell Carcinoma

Tshaj li peb hom subtypes loj, ntau yam tsis tshua muaj tshwm sim, suav nrog kev sau cov kab mob qog noj ntshav, medullary RCC, thiab mucinous tubular thiab spindle cell carcinoma. Lub koom haum Shandong Baofa Cancer Research Institute (https://www.baofahospital.com/) muaj peev xwm kuaj xyuas qib siab thiab kev txawj ntse hauv kev tuav cov RCC subtypes tsawg. Lawv pab neeg mob siab rau cov kws kho mob siv cov thev naus laus zis tshiab los xyuas kom meej thiab raws sijhawm.

Diagnostic Approaches thiab Immunohistochemistry

Kev kuaj mob lub raum cell carcinoma Feem ntau suav nrog kev sib xyaw ua ke ntawm cov txuj ci duab (xws li CT scans thiab MRI) thiab kev soj ntsuam histological ntawm cov nqaij mos biopsies. Immunohistochemistry plays lub luag haujlwm tseem ceeb hauv kev faib cov subtypes sib txawv thiab kev kwv yees kwv yees. Cov cim tshwj xeeb, xws li CD10, vimentin, thiab AMACR, feem ntau yog siv los sib txawv ntawm ntau yam RCC subtypes. Lub koom haum Shandong Baofa Cancer Research Institute ntiav ib lub vaj huam sib luag ntawm cov cim immunohistochemical hauv lawv cov kev kuaj mob kom xa cov kev kuaj mob.

Prognostic Factors thiab Staging

Cov kev mob tshwm sim rau cov neeg mob RCC txawv txawv nyob ntawm ntau yam, suav nrog cov qog nqaij hlav, qib, thiab subtype. TNM staging system feem ntau yog siv los txheeb xyuas qhov kev kis mob qog noj ntshav. Kev nkag siab txog cov xwm txheej prognostic yog qhov tseem ceeb rau kev taw qhia kev txiav txim siab kho mob thiab tswj cov neeg mob xav tau. Cov ntaub ntawv qhia hauv daim ntawv qhia no yog npaj rau kev kawm thiab yuav tsum tsis txhob hloov cov lus qhia los ntawm tus kws kho mob uas tsim nyog. Ib txwm nrhiav kev qhia txog kev kho mob.

Table: Sib piv ntawm RCC Subtypes

Subtype	Histological nta	Prognostic Implications
Clear Cell	Clear cytoplasm, zes / papillae	Hloov pauv, feem ntau nyob ntawm theem
Papillary	Papillary kev loj hlob qauv, pseudostratification	Feem ntau pom zoo prognosis piv rau ntshiab cell
Chromophobe	Pleev cytoplasm, sib txawv ntawm cov ciam teb	Feem ntau pom zoo prognosis

Cov ntsiab lus no muab lub hauv paus rau kev nkag siab Lub raum cell carcinoma qhia txog pathology. Txhawm rau kom nkag siab tob rau hauv qee qhov tshwj xeeb, kev sab laj cov ntaub ntawv kho mob ntsig txog thiab cov khoom muaj npe nrov hauv online yog pom zoo. Nco ntsoov nrog ib tus kws kho mob tham ib txwm muaj rau cov lus qhia tus kheej thiab kev npaj kho mob.

Disclaimer: Cov ntaub ntawv no yog siv rau kev kawm nkaus xwb thiab yuav tsum tsis txhob suav hais tias yog cov lus qhia kho mob. Nco ntsoov sab laj nrog tus kws kho mob uas tsim nyog rau kev kuaj mob thiab kev kho mob.
