Txhawm rau txhawm rau paub txog kabmob kheesxaws, qhov kev kuaj ntshav ntawm venous yog raug xa mus rau cov neeg mob. Ib qho ntawm lawv yog cov kab mob cancer-embryonic antigen, uas feem ntau yog siv rau hauv kev kuaj mob ntawm cov qog ntawm lub qhov quav thiab txoj hnyuv, tshwj xeeb tshaj yog cov xim thiav qab zib. Feem ntau, tus kabmob kheesxaws no yog siv los kuaj xyuas kev mob plab ntawm lub siab, lub mis, lub ntsws thiab lub plab.
Cancer-embryonic antigen lossis CEA yog dab tsi?
Cov qauv tshuaj ntawm cov lus nug nyob rau hauv cov lus nug muaj protein thiab carbohydrates, yog li nws hais txog glycoproteins.
REA yog nquag tsim los ntawm cov plab hnyuv siab raum ntawm lub plab zom hauv lub sijhawm thaum pib ntawm kev loj hlob hauv kev loj hlob, nws yog tsim los qhib kev sib npaug ntawm kev lag luam thiab tsim kho me nyuam hauv plab. Nyob rau hauv adulthood, antigen nyob rau hauv heev me me muaj peev xwm yuav tsim los ntawm ib tug noj qab haus huv tus kab mob, tab sis ib tug tseem ceeb nce nyob rau hauv nws cov concentration, raws li ib txoj cai, qhia qog kev ua nyob rau hauv cov nyuv los yog qhov quav. Qee zaum CEA nce vim yog kev mob ntawm autoimmune thiab cov kab mob ntawm cov kab mob hauv nruab nrog cev.
Nws yog tsim nyog teev tias tus kabmob cancer-embryonic antigen tseem raug xa mus rau CEA. Qhov txo qhov no los ntawm lub npe ntawm tus glycoprotein hauv Askiv - Carcino Embryonic Antigen.
Kev kuaj ntawm cancer-embryonic antigen nyob rau hauv cov poj niam
Qhov kev siv lossis qhov teev tseg ntawm qhov tseem ceeb rau CEA yog nyob ntawm ib qho me ntsis ntawm qhov tsis zoo ntawm kev coj cwj pwm.
Yog li, rau cov poj niam uas haus luam yeeb, tus kab mob cancer embryonic antigen li ntawm 5 mus rau 10 ng / ml ntshav.
Kev haus cawv, kev qhia no yog me ntsis siab dua - 7-10 ng / ml.
Yog hais tias ib tug poj niam tsis muaj cwj pwm phem, tus nqi ntawm CEA (CEA) yuav qis tshaj ntawm 0 mus rau 5 ng / ml.
Vim li cas thiaj yuav muaj peev xwm embryonic antigen siab?
Ib qho tseem ceeb ntxiv ntawm cov ntsiab lus piav qhia ntawm glycoprotein hauv cov ntshav yog pom hauv malignant hlav xws li plab hnyuv siab raum:
- tuab intestine tuab;
- qhov quav ;
- ntsws;
- lub plab;
- pancreas;
- mammary caj pas.
Tshaj dhau tus CEA ntawm ntau ntau zaus tshwm sim nrog rov qab kho cov kab mob oncological yav dhau los, nrog rau ntau cov metastases hauv pob txha, daim siab.
Tsis tas li ntawd, qhov nce hauv CEA tuaj yeem tshwm sim nrog cov kab mob uas tsis pub nqaij hlav:
- mob plab;
- kab mob siab ntsws ntev ntev;
- polyps nyob rau hauv lub qhov quav lossis cov plab hnyuv loj;
- cirrhosis ntawm lub siab;
- tuberculosis;
- cystic fibrosis;
- pancreatitis;
- bronchitis;
- raum tsis ua hauj lwm;
- emphysema ntawm lub ntsws;
- autoimmune pathologies;
- Crohn tus mob ;
- mob ntsws.
