Adenocarcinoma vs Squamous Cell Carcinoma
Adenocarcinoma thiab squamous cell carcinoma yog ob hom mob malignant. Cov no yuav tshwm sim zoo sib xws tab sis txawv ntawm qib cellular. Qee qhov adenocarcinomas muaj qhov cuam tshuam heev thaum lwm tus tsis yog. Nws tsis yog li ntawd nrog squamous cell carcinoma. Ob leeg mob qog noj ntshav feem ntau pom muaj nyob ntawm cov ntaub so ntswg. Ob leeg yog cov qog nqaij hlav epithelial. 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, ob qho tib si adenocarcinoma thiab squamous cell carcinoma xav tau kev pab kho mob, xov tooj cua, tshuaj kho mob, thiab phais kev phais kom kho thiab palliation.
Adenocarcinoma
Adenocarcinoma tuaj yeem tshwm sim nyob qhov twg nrog cov qog nqaij hlav. Adenocarcinoma yog ib qho kev hloov pauv ntawm cov qog nqaij hlav uas tsis tswj tau. Cov qog yog ua los ntawm cov kab mob epithelial. Cov qog yog endocrine los yog exocrine. Cov qog endocrine tso tawm lawv cov kua dej ncaj qha rau hauv cov ntshav. 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. 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 kev mob qog noj ntshav exocrine. Adenocarcinoma tuaj yeem kis tau nrog ntshav thiab qog ntshav. Lub siab, pob txha, ntsws thiab peritoneum yog qhov chaw paub ntawm metastatic deposits.
Squamous Cell Carcinoma
Squamous cells epithelium muaj nyob rau ntawm daim tawv nqaij, qhov quav, qhov ncauj, cov pa me me thiab ob peb qhov chaw. Kev faib tawm sai sai thiab rov ua dua cov ntaub so ntswg ntau dua rau cov qog nqaij hlav. Cov qog nqaij hlav no, yog li ntawd, pom nyob rau hauv cov cheeb tsam uas muaj cov kab mob squamous. Cov qog nqaij hlav no pom tau heev thiab yuav tsum tsis txhob nco. Squamous cell cancers tshwm sim raws li ulcers nrog nyuaj, tsa sawv. Cov qog nqaij hlav no yuav pib ua cov pigmentation txawv txav, caws pliav thiab cov qhov txhab yooj yim. Ntev ntev tsis kho cov kab mob nrog cov kab mob sib faib sai sai tuaj yeem hloov mus ua cov qog nqaij hlav squamous. Nws pom muaj nyob rau ntawm daim di ncauj ntawm cov neeg haus luam yeeb. Cov qog nqaij hlav cancer no tsis tshua kis nrog cov ntshav thiab cov qog ntshav, tab sis yuav muaj kev puas tsuaj loj ntawm cov ntaub so ntswg hauv zos. Squamous cell cancers yuav tsis meej pem nrog keratoacanthoma. Keratoacanthoma yog ib qho loj hlob sai, benign, nws tus kheej txwv tsis pub tsa qhov txhab nrog keratin ntsaws.
Kev kuaj mob ntawm lub qhov txhab ntawm lub qhov txhab biopsy nyob rau hauv lub tshuab kuaj kab mob yuav pom cov qog nqaij hlav cancer. Tom qab kuaj mob, tag nrho cov kev txiav txim hauv zos feem ntau yog kho tau.
Qhov txawv ntawm Adenocarcinoma thiab Squamous Cell Carcinoma yog dab tsi?
• Adenocarcinoma tuaj yeem tshwm sim nyob qhov twg nrog cov qog nqaij hlav thaum squamous cell carcinoma feem ntau tshwm sim ntawm daim tawv nqaij.
• Adenocarcinoma tshwm sim los ntawm cov qog nqaij hlav thaum cov qog nqaij hlav squamous cell tshwm sim los ntawm cov hlwb squamous.
• Adenocarcinoma tuaj yeem metastasize ntau zaus thaum cov qog nqaij hlav squamous cell tsis tshua muaj metastasize.
• Kev txiav tawm hauv zos feem ntau kho mob qog noj ntshav hauv cov qog nqaij hlav qog nqaij hlav thaum nws tsis tuaj yeem yog tus mob adenocarcinoma.
