Cov txiaj ntsig ntawm qhov kev kwv yees qhov txiaj ntsig zoo tau pom tias muaj kev ntseeg siab tsawg.Peb qhov kev tshawb pom tau qhia meej tias kev ntxhov siab immobilization ua rau muaj txiaj ntsig zoo rau qib CEA seb qhov kev ntxhov siab yog mob lossis mob ntev. Raws li peb qhov kev tshawb pom, muaj cov ntaub ntawv qhia tias kev ntxhov siab tuaj yeem ua rau cov qog loj hlob thiab cov qog nqaij hlav qhia [26, 27].

Q: Dab tsi ua rau qib CEA nce?

A: Carcinoembryonic antigen (CEA) yog ib qho oncofetal glycoprotein uas ib txwm qhia los ntawm mucosal hlwb. Nws yog overexpressed los ntawm ntau yam malignancies. Txawm hais tias nws feem ntau cuam tshuam nrog kev mob qog nqaij hlav hauv plab, nws tuaj yeem nce siab hauv lwm yam malignancies xws li lub mis, siab, plab, thiab pancreas [1].

Q: Puas yog CEA kuaj mob qog noj ntshav?

A: CEA yog qhov qhia tau ntau tshaj plaws ntawm kev rov tshwm sim hauv cov neeg mob asymptomatic thiab tam sim no yog qhov kev ntsuas tus nqi zoo tshaj plaws rau kev kuaj pom tus kab mob kho dua tshiab. CEA yog qhov tseem ceeb tshaj plaws rau kev tshawb pom ntxov ntawm daim siab metastasis hauv cov neeg mob uas kuaj mob qog nqaij hlav hauv lub cev.CEA yog ntsuas hauv cov ntshav thiab qhov ib txwm muaj.<2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker. The most common cancers that elevate CEA are in the colon and rectum but it can be elevated with gastric, ovarian and other cancers.

Q: Ntev npaum li cas yuav tsum tau xeem CEA?

A: Piv txwv li National Comprehensive Cancer Network, pom zoo tias cov neeg kho mob rau theem II lossis III txoj hnyuv loj lossis mob qog noj ntshav tau kuaj CEA txhua 3 txog 6 lub hlis rau 2 xyoos thiab tom qab ntawd txhua 6 lub hlis rau 3 xyoos ntxiv, ntxiv rau CT scans. Txhua txhua 6 mus rau 12 lub hlis rau 5 xyoos.Tom qab ua tiav kev phais mob qog noj ntshav, qhov nce CEA concentration yuav tsum rov qab zoo li qub hauv 4 mus rau 6 lub lis piam. Kev ua tsis tiav ntawm qib ua ntej ua ntej kom txo qis mus rau qhov qub li ntawm 6 lub lis piam ntawm kev phais mob feem ntau cuam tshuam nrog cov kab mob rov tshwm sim.
