PSA protein yog ib qho prostate-specific antigen tsim los ntawm cov ntaub so ntswg ntawm prostate caj pas. Cov protein no yuav tsum tau liquefy txiv neej phev. Nws yuav tsum tau muab sau tseg tias malignant neoplasms tsim ib tug ntau ntawm cov khoom no. Tias yog vim li cas PSA yog siv los ua cov qog nqaij hlav cancer prostate. Nyob rau tib lub sijhawm, txhua tus txheej txheem pathological tuaj yeem cuam tshuam rau cov protein tsim tawm. Yog li, PSA tsom xam rau prostatitis yog yuav tsum tau. Nws yuav tso cai rau txheeb xyuas oncology lossis adenoma.
Vim li cas Protein qib nce
Txhawm rau txiav txim siab qib protein, kev kuaj ntshav PSA dav dav yog muab rau tus mob prostatitis. Cov qauv ntawm cov tshuaj tiv thaiv yog tsis ntau tshaj 4 ng / ml. Kev tsim cov protein no nce ntau heev thaum tsim cov qog nqaij hlav malignant. Txwv tsis pub, kev tsim cov antigen nce vim yog lwm yam:
- PSA qib tuaj yeem nce siab vim tias muaj kev kis kab mob uas nrog cov txheej txheem inflammatory. Hauv qhov no, muaj kev ua txhaum ntawm kev ua haujlwm ntawm cov ntaub so ntswg, uas tso cai rau cov tshuaj maj mam nkag mus rau hauv cov ntshav.
- YProteintuaj yeem nkag mus rau hauv cov hlab ntsha ntau dua yog tias cov ntaub so ntswg overgrown nrog benign prostatic hyperplasia pib ua rau lub siab ntawm cov ntaub so ntswg ntawm lub cev.
Nws yog ib qho tsim nyog sau cia tias PSA tsom xam rau prostatitis tso cai rau koj txheeb xyuas qhov txawv txav thiab kev ua haujlwm ntawm lub caj pas prostate. Feem ntau cov txiv neej uas muaj qib antigen siab tsis raug kev txom nyem los ntawm oncology. Cov qib protein ntau tuaj yeem nce ntxiv raws li qhov tshwm sim ntawm kev phais zais zis lossis qog nqaij hlav prostate, nrog rau ejaculation thiab kev tawm dag zog ntev.
Thaum kev tshuaj ntsuam raug txiav txim
Tsis yog tus mob prostatitis xwb, koj yuav tsum tau xeem PSA. Qhov kev kuaj sim no tau muab rau:
- Txhawm rau saib xyuas kev mob qog noj ntshav prostate. Qhov no tso cai rau koj los txheeb xyuas qhov ua tau zoo ntawm txoj kev kho mob xaiv.
- Yog tias koj xav tias tsim cov qog ntawm prostate. Qhov no tuaj yeem tshwm sim los ntawm lwm cov kev tshawb fawb: ultrasound, kuaj lub qhov quav digital, thiab lwm yam.
- Kev tiv thaiv. Qhov kev tshuaj ntsuam no yog muab rau cov txiv neej hnub nyoog tshaj 40 xyoo los kuaj pom qhov nce ntawm PSA.
- Tom qab kev kho mob antitumor, uas tau ua tom qab tshawb pom tus mob qog noj ntshav prostate. Tom qab kev kho zoo li no, nws raug nquahu kom kuaj xyuas qhov no txhua 3 lub hlis.
Npaj rau kev tshuaj ntsuam
Txhawm rau kuaj PSA rau prostatitis, koj yuav tsum ua tib zoo npaj. Txwv tsis pub, kev nyeem ntawv qib protein yuav tsis raug. Cov kws tshaj lijrecommend:
- Rau 8 teev ua ntej pub ntshav, tsis kam noj zaub mov, suav nrog cawv, kas fes, tshuaj yej thiab kua txiv hmab txiv ntoo.
- Koj yuav tsum tsis txhob sib deev 5-7 hnub ua ntej kuaj.
- Kev tshuaj xyuas yuav tsum tau noj 12-14 hnub tom qab kuaj xyuas los ntawm tus kws kho mob urologist lossis ua ntej mus ntsib tus kws kho mob tshwj xeeb.
- Yog tias kev zaws prostate, transrectal ultrasound, zais zis catheterization lossis cystoscopy, kuaj ntiv tes ntawm qhov quav lossis lwm yam teebmeem ntawm prostate tau ua, ces kev tshuaj xyuas yuav tsum tau noj 2 lub lis piam tom qab cov kev tshawb fawb no, thiab tom qab kuaj xyuas cov ntaub so ntswg prostate. - tom qab 1 lub hlis.
Kev tshawb fawb tau ua hauv chav kuaj hauv ib hnub. Rau qhov no, tus neeg mob yuav tsum tau sau daim ntawv xa mus los ntawm tus kws kho mob tuaj koom, npaj, thiab tom qab ntawd muab cov ntshav los ntawm cov hlab ntsha. Qee qhov xwm txheej, kev txiav txim siab ntawm tag nrho PSA lossis antigen dawb yog xav tau. Qhov no yog qhov yuav tsum tau rau kev kuaj mob kom raug.
Yuav ua li cas nkag siab cov txiaj ntsig
PSA tsom xam rau prostatitis tuaj yeem txhais tau ntau txoj hauv kev. Cov qib antigen feem ntau yog ntsuas hauv nanograms ib milliliter ntawm cov ntshav. Nyob rau tib lub sijhawm, qee cov kws tshaj lij tau sib cav tias nws yog qhov tsim nyog kom txo qis qhov tsawg kawg nkaus rau 2.5 ng / mg. Qhov no, ntawm chav kawm, tso cai rau kuaj pom cov kab mob prostate ntau dua. Txawm li cas los xij, muaj kev pheej hmoo tias cov kws kho mob, raws li qhov kev sim no, yuav pib kho mob qog noj ntshav uas tsis muaj feem cuam tshuam txog kev kho mob. Thaum ua qhov kev kuaj mob, tsuas yog peb hom protein tau muab rau hauv tus account:
- Prostate dawb tshwj xeeb antigen. Nws pom nyob rau hauv cov ntshav thiab tsuas yog 20% ntawm tag nrho cov qib PSA.
- Y Protein txuam nrog a2-macroglobulin lossis a1-antichymotrypsin. Tsuas yog hom kawg ntawm antigen tuaj yeem txiav txim siab hauv chav kuaj.
- PSA tag nrho yog cov protein uas nkag mus rau hauv cov hlab ntsha.
Qhia txog prostatitis
Prostatitis, qhov tseeb, tsis yog kab mob malignant. Tom qab tag nrho, nws tsis txawm nce qhov yuav tshwm sim ntawm cov qog nqaij hlav cancer. Txawm li cas los xij, kev saib xyuas cov qib PSA tsis tu ncua tso cai rau tus kws kho mob kom raug kho kom raug txhawm rau tshem tawm cov txheej txheem inflammatory.
Yog tias qhov concentration ntawm cov tshuaj tiv thaiv yog los ntawm 4 mus rau 10 ng / ml, ces qhov no yuav qhia tau tias kev loj hlob ntawm cov kab mob hauv qab no:
- prostatitis;
- benign prostatic hyperplasia;
- mob qog noj ntshav prostate, qhov no, qhov kev pheej hmoo ntawm kev kuaj mob tus kab mob no nce 25%.
Nws yog ib qho tsim nyog sau cia tias cov kws tshaj lij hu ua qhov taw qhia ntawm PSA qib ib cheeb tsam grey. Yog tias qhov concentration ntawm cov tshuaj tiv thaiv nce ntau dua 10 ng / ml, qhov tshwm sim ntawm kev tsim cov txheej txheem oncological nce li ntawm 67%.
Ntau zaus, theem ntawm tag nrho PSA ncaj qha nyob ntawm hom kab mob prostate. Qhov kev tshuaj ntsuam no feem ntau siv rau kev kuaj mob sib txawv.
kab mob txhais li cas
Yog tsom xamntshav PSA tag nrho rau prostatitis yog ua tiav lawm, thiab qib protein tsawg kawg yog 4 ng / ml thiab tsis ntau tshaj 10 ng / ml, tom qab ntawd thaum kuaj mob, cov kws kho mob saib cov feem ntawm cov protein hauv qab no thiab lawv qhov sib piv:
- Txo qhov concentration ntawm dawb antigen ua rau muaj kev pheej hmoo ntawm mob qog noj ntshav. Qhov no yog vim lub fact tias malignant hlwb tsim ib tug loj npaum li cas ntawm a1-atichymotrypsin. Qhov no ua rau kom daim ntawv khi ntawm cov protein.
- Kev nce siab ntawm cov antigen dawb, ntawm qhov tsis sib xws, txo qhov kev pheej hmoo ntawm kev tsim oncology. Ntxiv mus, qhov ntsuas no kuj tseem qhia tau tias muaj tus mob prostatitis ntev.
cov ntaub ntawv ntxiv
Kev kuaj ntshav PSA dav dav rau prostatitis, tus nqi uas tau teev tseg hauv tsev kho mob, tau pom zoo kom coj los ntawm cov txiv neej hnub nyoog tshaj 50 xyoo txhua xyoo. Nyob rau tib lub sijhawm, txhawm rau txhim kho qhov kev sim, cov kws tshaj lij tau qhia cov ntsuas ntxiv uas tso cai rau peb los txiav txim siab cov protein raws li ntau yam tsis muaj.
Thaum ua qhov kev soj ntsuam, qhov ceev ntawm PSA raug suav nrog. Qhov no tso cai rau kev suav cov antigen concentration nyob rau hauv kev sib raug zoo rau qhov loj ntawm lub caj pas nws tus kheej, uas yog txiav txim los ntawm transrectal ultrasound. Cov protein tsawg tsawg yuav qhia tau tias lub ntsiab yog vim li cas rau nws txoj kev loj hlob yog nyob rau hauv kev loj hlob ntawm prostatitis.
