Masifumanise ngovavanyo lwakho lwe-CEA (iCarcinoembryonic Antigen)? Njengogqirha, ndiza kukuxelela oku ngokulula!

Usenokuba ukhe weva ngovavanyo lwe-CEA, okanye ugqirha wakho usenokuba ukuxelele ukuba ulwenze. Ngoko ke, luyintoni uvavanyo lwe-CEA? Kutheni lwenziwa? Ndiyazi ukuba unemibuzo emininzi efana nale engqondweni yakho. Ungakhathazeki, namhlanje siza kuthetha ngovavanyo lwe-CEA ngendlela elula onokuyiqonda. Ndiyazi ukuba xa usiva izinto ezinje, uziva usoyika kancinci, kodwa wakuba uzazi iinkcukacha, olo loyiko luya kuphela.

Yintoni i-CEA (i-Carcinoembryonic Antigen)? Masiyiqonde ngokulula!

Khawucinge nje, sinohlobo oluthile lweproteni emizimbeni yethu. Oku sikubiza ngokuba yi-CEA, okanye i-Carcinoembryonic Antigen . Le yiproteni eneswekile eninzi enamathele kuyo. Ezi zinokuveliswa ziiseli eziqhelekileyo kunye nezinye iiseli zomhlaza.

Yinto engaqhelekanga kakhulu ukuba xa sizalwa sonke, sinezinga eliphezulu le-CEA emizimbeni yethu. Njengoko sikhula, oko kukuthi, njengoko sikhula, eli zinga le-CEA liyehla kancinci kancinci. Nangona kunjalo, kwezinye iimeko zesifo, ingakumbi xa kuvela iintlobo ezithile zomhlaza, izinga le-CEA egazini lethu linokunyuka kwakhona.

Izazinzulu zaqala ukufumana i-CEA ngo-1968, xa zazihlola iindawo zomhlaza we-colorectal ezazisele zingene esibindini nakwiindawo zokugaya ukutya zemveku esempilweni.

Ngamanye amaxesha i-CEA ikwabizwa ngokuba yi-tumor marker okanye i-tumor antigen . Iimpawu ze-tumor zizinto ezenziwe ziiseli ezithile zomhlaza kwaye zongezwa kulwelo lomzimba wethu (njengegazi nomchamo). Kodwa khumbula, iiseli ezisempilweni nazo zenza ezi zimpawu ze-tumor, kodwa ngobuninzi obuncinci kakhulu. Uninzi lwabantu abasempilweni banazo ezi "kwi-normal range." Ingxelo yakho yelebhu ingachaza oku njenge "normal range," "reference range," okanye "reference interval."

Zeziphi iintlobo zomhlaza ezisetyenziselwa uvavanyo lwe-CEA ikakhulu?

Kulapho abantu abaninzi benza khona impazamo. Uvavanyo lwe-CEA alunakukwazi ukuxelela ngokuqinisekileyo ukuba unomhlaza okanye awunawo. Oko kukuthi, asilulo uvavanyo lokuhlola ukuze kufunyaniswe ukuba unomhlaza na.

Kutheni ke oku kwenziwa? Isetyenziswa kakhulu kubantu abasele befunyenwe benomhlaza. Oku kubaluleke kakhulu kubantu abanomhlaza we-colorectal.

Oogqirha basebenzisa uvavanyo lwe-CEA kunye nezinye iimvavanyo ukuxilonga, ukunyanga, kunye nokubeka esweni iintlobo ngeentlobo zomhlaza. Umzekelo, lusetyenziswa ekuxilongeni umhlaza wesinyi, umhlaza webele, umhlaza wemiphunga, umhlaza wesibeleko, kunye nomhlaza we-thyroid.

Ngamafutshane, uvavanyo lwe-CEA lusetyenziselwa ukubona indlela isigulane esisabela ngayo kunyango lomhlaza, ukubona ukuba isifo sibuyile na (ukubuyela umva), okanye ukufumanisa ukuba umhlaza ubuyile na (ukubuyela umva). Kodwa olu vavanyo alusetyenziswa lodwa. Ugqirha wakho ulusebenzisa kunye novavanyo lomzimba, kwaye ukuba kuyimfuneko, uvavanyo lwemifanekiso.

Ngoko ke, kuphantsi kweziphi iimeko apho uvavanyo lwe-CEA luyimfuneko khona?

Njengoko benditshilo ngaphambili, uvavanyo lwe-CEA alusetyenziselwa ukuxilonga umhlaza. Nangona kunjalo, ukuba sele unomhlaza, olu vavanyo lunokubonelela ngolwazi olubaluleke kakhulu. Ugqirha wakho angasebenzisa uvavanyo lwe-CEA uku:

• Jonga ukuba umhlaza ukhulile okanye usasazeke na kwezinye iindawo zomzimba (usususwe kwi-metastasized).
• Vavanya ukuba unyango lomhlaza luphumelela kangakanani na. Kusenokufuneka ukuba olu vavanyo lwenziwe kwezi meko zilandelayo:
• Xa isifo sifunyenwe, kuyanceda ekuphuhliseni isicwangciso sonyango (oku kubizwa ngokuba 'luvavanyo lokuqala ').
• Ngexesha lonyango lomhlaza (umz., jonga indlela unyango olufana ne-chemotherapy, i-immunotherapy, kunye ne-radiation therapy olusebenza ngayo).
• Emva kokuba unyango lugqityiwe ngokupheleleyo, jonga ukuba umhlaza ubuyile na (ukuphinda ubuye).
• Emva kokuba ufunyenwe unomhlaza, ngaphambi konyango kunye/okanye utyando. Emva koko, ngexesha lonyango, olu vavanyo lwenziwa kanye ngenyanga okanye rhoqo emva kweenyanga ezintathu.
• Kodwa nantsi into ebalulekileyo ekufuneka uyiqaphele: Ukunyuka kwamanqanaba e-CEA kwiiveki ezi-4-6 emva kokuqala unyango akuthethi ukuba unyango luye lwasilela, ukuba isifo siphinde sabuya, okanye ukuba umhlaza ubuyile. Ugqirha wakho uza kukuxelela okungakumbi ngale nto.
• Xa isifo siphelile, kunokufuneka uqhubeke novavanyo lwe-CEA ukuze ujonge ukuba siphinde sibuye na. Ugqirha wakho uya kugqiba ukuba oku kwenziwa kangaphi.

Ulwenza njani olu vavanyo lwe-CEA?

Amaxesha amaninzi, uvavanyo lwe-CEA lwenziwa njengovavanyo lwegazi . Ugqirha okanye umongikazi wakho uza kuthatha isampuli encinci yegazi kumthambo osengalweni yakho. Emva koko, iingcali kwilebhu ziya kuhlola loo sampuli yegazi zize zijonge inqanaba le-CEA.

Kodwa kunqabile kakhulu, ugqirha wakho angajonga amanqanaba e-CEA kwezinye izinto eziphuma emzimbeni. Umzekelo:

• Ulwelo lwesisu (ulwelo oluthathwe eludongeni lomngxuma wesisu)
• Ulwelo lwePleural
• Ulwelo oluthathwe kwi-spinal cord (oku kubizwa ngokuba yi-"cerebrospinal fluid okanye i-CSF")

Kwimeko enjalo, ugqirha wakho uza kusebenzisa inaliti okanye isirinji ukuthatha isampuli encinci yolwelo. Inaliti ifakwa esifubeni sakho okanye emqolo ongezantsi.

Ndingazilungiselela njani uvavanyo lwe-CEA?

Akukho mfuneko yokulungiselela okuninzi oku. Ugqirha wakho uza kukuxelela indlela yokulungiselela. Usenokucelwa ukuba uyeke ukusebenzisa amayeza athile anyusa ukopha (njenge-aspirin) kangangeentsuku ezimbalwa. Ugqirha wakho uza kukuchazela konke oku.

Yintoni onokuyilindela xa ubhala uvavanyo lwe-CEA?

Ukuba i-CEA ilinganiswa egazini:

• Ugqirha okanye umongikazi uza kufaka inaliti encinci emthanjeni osengalweni yakho (ngesiqhelo kufutshane nengqiniba yakho).
• Ibhotile encinci (ibhotile) okanye ityhubhu yovavanyo iqhagamshelwe kuyo.
• Emva koko kuthathwa isampuli yegazi encinci. Oku kuthatha ngaphantsi kwemizuzu emihlanu.

Ukuba isampuli ithathwe kolunye ulwelo lomzimba (umz., ulwelo lomqolo):

• Okokuqala, kufakwa isibulali-zintlungu sasekuhlaleni kumqolo wakho ongezantsi nasesifubeni ukuze singasebenzi kakuhle.
• Emva koko kufakwa inaliti okanye isirinji ngendlela echanekileyo.
• Ngamanye amaxesha, i-X-ray isetyenziswa ukujonga ukuba inaliti ikwindawo efanelekileyo na.
• Emva koko kuthathwa isampuli ye-`(CSF),` `(pleural fluid)` okanye `(peritoneal fluid)`.

Olu hlobo lovavanyo ludla ngokuthatha malunga nemizuzu engama-30. Ungagoduka ngosuku olunye novavanyo.

Ngaba kukho naziphi na iingozi ngovavanyo lwe-CEA?

Uvavanyo lwe-CEA luhlala lukhuselekile kakhulu. Nangona kunjalo, kukho umngcipheko omncinci kakhulu wolu vavanyo ngexesha lovavanyo lwe-pleural fluid:

• Kusenokubakho ukopha okuthile.
• Kusenokubakho usulelo.
• Kusenokubakho umonakalo omncinci emiphungeni.

Kodwa uninzi lwabantu alufumani ngxaki xa luvavanywa yi-CEA. Ugqirha wakho uza kukuchazela ezi ngozi ngokweenkcukacha ngaphambi kovavanyo. Ngoko ke akukho nto ibalulekileyo.

Ziziphi iziphumo ebezingalindelekanga ezinokwenzeka emva kovavanyo lwe-CEA?

Ukuba uvavanyiwe igazi, usenokuba nemikrwelo okanye ukudumba okuncinci apho inaliti ifakwe khona kangangeentsuku ezimbini okanye ezintathu. Oku kuqhelekile.

Ukuba kuthathwa isampuli yolwelo lwakho lwe-cerebrospinal (CSF) okanye ulwelo lwesisu, unokufumana iziphumo ebezingalindelekanga ezincinci ezifana nezi:

• Isiyezi
• Intloko ebuhlungu
• Ubukrelekrele

Ezi zihlala zisiba ngcono kwiintsuku ezimbalwa.

Zithetha ukuthini iziphumo zovavanyo lwe-CEA?

Ugqirha wakho usebenzisa iziphumo zovavanyo lwe-CEA ukuze afunde ngakumbi ngomhlaza.

• Ukuba inqanaba le-CEA liphantsi, oko kuthetha ukuba ithumba lincinci kwaye alisasazekanga kwamanye amalungu omzimba. Nangona kunjalo, ezinye iintlobo zomhlaza (ingakumbi ezo zikwiindawo ezifana nobuchopho) azivelisi i-CEA ingako. Kwimeko enjalo, ixabiso lovavanyo lwegazi lwe-CEA linokuba liphantsi. Kwimeko enjalo, oogqirha banokuqwalasela iiskeni ezifana ne-MRI.
• Ukuba inqanaba le-CEA liphezulu, oko kuthetha ukuba umhlaza mkhulu okanye usasazeke kwamanye amalungu omzimba.Kodwa khumbula, amanqanaba e-CEA ewodwa awanakukuxelela ukuba umhlaza ukuliphi inqanaba (ukukhula kwe-tumor) okanye ukuba sele usasazeke na kwamanye amalungu omzimba (ukukhula kwe-metastasized).

Ugqirha wakho unokujonga amanqanaba akho e-CEA kulo lonke unyango lwakho lomhlaza. Ukuba amanqanaba akho e-CEA ehla kakhulu ngexesha lonyango, oku kudla ngokubonisa ukuba unyango luyasebenza. Nangona kunjalo, oogqirha baya kuqinisekisa oku ngovavanyo lomzimba kunye neeskeni.

Ithini inqanaba eliqhelekileyo le-CEA?

Amanqanaba e-CEA adla ngokuxelwa kwii -nanograms nge-milliliter (ng/mL) . Inqanaba eliqhelekileyo liphakathi kwe-0 kunye ne-2.9 ng/mL.

Oogqirha ngokubanzi bacinga ukuba inqanaba le-CEA eliphakathi kwe-0 kunye ne-2.9 ng/mL liqhelekile. Nangona kunjalo, uphando oluthile lubonise ukuba amanqanaba aphezulu njenge-35 ng/mL anokubangela iziphumo ezingezizo ezilungileyo. Oku kuthetha ukuba i-CEA inokunyuka nokuba akukho mhlaza.

Olu luhlu oluqhelekileyo (uluhlu lwereferensi) lunokwahluka kancinci phakathi kweelebhu, kwaye oogqirha banokuqwalasela imida ephezulu ngokuxhomekeke kwimeko yesigulana ngasinye.

Ithini inqanaba le-CEA elibonisa umhlaza?

Nantsi ingongoma ebalulekileyo. Akukho nqanaba lithile le-CEA elinokuqikelela ngokuchanekileyo ukuba kukho umhlaza. Njengoko benditshilo ngaphambili, oogqirha abasebenzisi uvavanyo lwe-CEA ukuvavanya okanye ukuxilonga umhlaza. Ngokubanzi, inqanaba le-CEA elingaphezulu kwe-2.9 `(ng/mL)` lithathwa njengelingaqhelekanga, kodwa akuthethi ukuba umhlaza ukhona rhoqo.

Ngaba amanqanaba e-CEA angaphakanyiswa ngaphandle komhlaza?

Ewe, ngokuqinisekileyo inokwenzeka! Inqanaba eliphezulu le-CEA alithethi ukuba kukho umhlaza rhoqo. Umzekelo, abantu abatshayayo banokuba namanqanaba aphezulu e-CEA.

Amanqanaba e-CEA anokuphakanyiswa ngenxa yeemeko ezingezizo zomhlaza ezifana nezi:

• I-Gastritis kunye nezilonda zesisu
• Isifo Esingapheliyo Sokuqanda Amaphaphu (i-COPD)
• Isifo sesibindi, umzekelo isifo sesibindi, isibindi esinamafutha, okanye amatye enyongo
• I-Diverticulitis kukudumba kweengxowa ezincinci emathunjini amakhulu.
• Isifo seswekile
• Nasiphi na isifo sokuzikhusela komzimba okanye isifo sokudumba
• Izifo zokudumba kwamathumbu (umz. isifo sikaCrohn kunye ne-ulcerative colitis)
• IiHemorrhoids
• Inyumoniya (kuquka inyumoniya ye-COVID-19)

Kwakhona, abantu abathatha unyango oluthile olwenziwe ngezinto zezilwanyana (umz., ii-antibodies ze-monoclonal) banokuba namanqanaba aphezulu e-CEA.

Ngoko ke, zeziphi izinto zokugqibela ekufuneka uzikhumbule? (Umyalezo Wokubuyela Ekhaya)

Kulungile, sithethe kakhulu ngovavanyo lwe-CEA ngoku. Ndiyathemba ukuba uluqonda kakuhle. Ukushwankathela:

• I-CEA yiproteni ekhethekileyo (i-glycoprotein) emzimbeni wethu.
• Ezinye iintlobo zomhlaza zinokubangela ukunyuka kwamanqanaba e-CEA. Nangona kunjalo, ukunyuka kwamanqanaba e-CEA akuthethi ukuba kukho umhlaza rhoqo. Zininzi izizathu zokuba i-CEA inokwandiswa nokuba akukho mhlaza.
• Uvavanyo lwe-CEA alulovavanyo lokufumanisa umhlaza.
• Oku kusetyenziswa kakhulu ukubona indlela abantu abasele befunyenwe benomhlaza abasabela ngayo kunyango kunye nokulandelela esi sifo.
• Ukuba unemibuzo malunga nenqanaba lakho le-CEA okanye uvavanyo, thetha nogqirha wakho. Baza kukunika icebiso elihle kakhulu.

Khumbula, kwezonyango, uvavanyo olunye alunakuchaza yonke into. I-CEA yenye nje yeendlela ezinjalo. Ugqirha wakho uya kwenza izigqibo ezilungileyo ngokusekelwe kwimpilo yakho iyonke. Ngoko ke, ungoyiki okanye uxhalabe ngokungeyomfuneko. Thetha nogqirha wakho ngayo nantoni na uze uyisombulule.
