Adenoma vs Adenocarcinoma
Adenoma thiab adenocarcinoma yog ob qho tib si kev loj hlob ntawm cov qog nqaij hlav. Ob leeg tuaj yeem tshwm sim nyob txhua qhov chaw uas muaj cov qog nqaij hlav. Cov qog yog endocrine los yog exocrine. Cov qog endocrine tso tawm lawv cov kua dej ncaj qha rau hauv cov hlab ntsha. Cov qog exocrine tso tawm lawv cov kua qaub rau ntawm qhov chaw epithelial los ntawm txoj hlab pas. Exocrine caj pas tej zaum yuav yooj yim los yog complex. Tej yam yooj yim exocrine caj pas muaj ib tug luv luv un-branched duct uas qhib rau ib tug epithelial nto. Piv txwv li: duodenal qog. Cov qog tsis yooj yim tuaj yeem muaj cov kab hluav taws xob thiab cov kab mob acinar nyob ib ncig ntawm txhua qhov duct. Piv txwv li: lub mis. (Nyeem ntxiv txog qhov txawv ntawm Endocrine thiab Exocrine Glands.) Cov qog tuaj yeem muab faib ua ob pawg raws li lawv cov tsos mob histological. Tubular glands feem ntau yog ib qho kab ke ntawm cov ducts uas qhov muag tsis pom qhov kawg yog secretory. Acinar caj pas muaj cov kab mob ntawm tes ntawm qhov kawg ntawm txhua qhov duct. Pituitary prolactinoma yog ib qho piv txwv ntawm kev mob qog noj ntshav endocrine. Lub mis adenocarcinoma yog ib qho piv txwv ntawm tus kab mob exocrine.
Adenoma
Adenomas yog cov qog nqaij hlav tsis zoo. Lawv tuaj yeem yog microadenomas lossis macroadenomas. Microadenomas tsis ua rau muaj kev ntxhov siab vim lawv tsis nias tawm tsam cov qauv uas nyob ib sab. Macroadenomas ua rau muaj kev ntxhov siab. Pituitary microadenomas tuaj yeem tshwm sim raws li cov kua mis tso tawm ntawm lub mis yam tsis muaj tsos mob lossis mob taub hau. Pituitary microadenomas nias ntawm optic chiasma thiab ua rau mob taub hau thiab bitemporal hemianopia. Adenomas tsis kis mus rau qhov chaw deb ntawm cov ntshav thiab lymph. Lawv tsuas pom cov teebmeem hauv zos xwb, thiab txawm tias qhov ntawd tsis tshwm sim.
Adenocarcinoma
Adenocarcinoma tuaj yeem tshwm sim nyob txhua qhov chaw uas muaj cov qog nqaij hlav. Adenocarcinoma yog ib qho kev hloov pauv ntawm cov qog nqaij hlav uas tsis tswj tau. Adenocarcinomas tuaj yeem kis tau hauv zos los ntawm kev tua cov leeg ntawm cov hlwb los ntawm cov ntaub so ntswg hauv qab daus rau hauv cov ntaub so ntswg. Adenocarcinoma tuaj yeem kis tau nrog ntshav thiab qog ntshav. Lub siab, pob txha, ntsws thiab peritoneum yog qhov chaw paub ntawm metastatic deposits. Yog li ntawd, Adenocarcinoma yog ib tug mob malignant. Nws tuaj yeem tshwm sim qee zaum zoo li adenomas tab sis txawv ntawm qib cellular. Kev mob qog noj ntshav tau xav tias yog vim qhov txawv txav ntawm caj ces taw qhia uas txhawb nqa kev tswj tsis tau ntawm tes. Muaj cov noob hu ua proto-oncogene, nrog kev hloov pauv yooj yim, uas tuaj yeem ua rau mob qog noj ntshav. Mechanisms ntawm cov kev hloov pauv no tsis to taub meej. Ob tug hit hypothesis yog ib qho piv txwv ntawm xws li ib tug mechanism. Raws li kev mob qog noj ntshav, kev sib kis thiab cov txiaj ntsig ntawm tus neeg mob adenocarcinoma xav tau kev txhawb nqa kev kho mob, xov tooj cua, kws khomob, phais phais kom kho thiab palliation.
Qhov txawv ntawm Adenoma thiab Adenocarcinoma yog dab tsi?
• Adenocarcinoma thiab adenoma tuaj yeem tshwm sim nyob txhua qhov chaw uas muaj cov qog nqaij hlav.
• Adenomas yog tsim los ntawm cov hlwb nrog ib txwm morphology tsis muaj cov cim malignant.
• Adenocarcinoma cells qhia cellular atypia thiab mitotic lub cev.
• Adenocarcinoma tuaj yeem ua rau ntau zaus adenomas tsis metastasize.
• Kev txiav tawm hauv zos yog kho hauv adenomas thaum nws tsis tuaj yeem ua rau adenocarcinoma.
