Kukho ingozi yangempela yokuba ukuhlolwa kwe-PSA kuya kukhokelela ekugqibeleni. Urhulumente, emva kokuba afunde le meko, uye wakhuthaza ukuyeka ukuhlolwa kwe-PSA ngokupheleleyo. Esi siphakamiso asibonakali simnandi xa ucinga ukuba inkqubo yangoku ihlolisise amadoda angama-100 000 anesifo esiphantsi kwesibalo minyaka yonke. Izifundo zibonisa ukuba aba-70,000 bala madoda baxhamla ngokukhawuleza kwindlela yokuhlinzwa okanye imisebe yelanga, nangona ayinakwandisa ubomi babo.
Ukutshatyalaliswa kwengcamango karhulumente yokujonga ukuhlolwa kwe-PSA kuyayigxeka inyaniso eqinisekisiwe yokuba ukufunyanwa kwangaphambili kwezifo eziphezulu kusindisa ubomi. Ukuqwalasela i-PSA yokuhlola iphela kukuthi "ukuphosa umntwana kunye namanzi okuhlamba."
Uvavanyo olujongene nomhlaza we-prostate uvavanyo lokuhlola i-prostate luya kubona izifo eziphezulu kakhulu ngelixa lijongene nazo zonke izinto ezingenakubungozi. Ngelishwa, inkqubo yenkqubo-leyo yokuvavanya nayiphi na i-PSA engaqhelekanga nge-12-core core random biopsy-ifumana izifo eziphezulu kunye nezifundo eziphantsi kwezinga elifanayo. Kwaye ngelishwa, izifo ezisezantsi zibizwa ngokuba "ngumhlaza," zibeka ukwesaba okukhulu. Amava abonisa ukuba nayiphi na into ebizwa ngokuba ngumhlaza, kungakhathaliseki ukuba ibizwa ngokuba "ibakala eliphantsi," ngokuqhelekileyo kukhokelela ekusebenziseni ngokukhawuleza okanye kumbane ngaphandle kokuba kungadingekile.
Ukuthayatha
Amadoda aqalisa inkqubo yokucoca i-PSA, ngoko ke, kufuneka athathe amanyathelo amanyathelo okukhusela ukukhusela ukuxhamla kwimeko enhle, eyoyikisayo.
Okokuqala, indoda kufuneka yazi ukuba i-PSA yakhe yinto eqhelekileyo okanye engaqhelekanga njengoko ihambelana nobukhulu beprotate yakhe. I-PSA ephakamileyo ingaba nomhlaza, kodwa ingaba ngenxa ye-prostate gland enefuthe. Njengabantu abaneminyaka yobudala, ii-prostates zabo zivame ukukhula kwaye zivelise iPSA. Ukunyuka kwi-PSA kwi-prostate gland eyandisiweyo ingakwazi ukungahambelani ngokupheleleyo nomhlaza .
Ngoko xa ugqirha ekuxelela ukuba, "I-PSA yakho iphakamileyo, ndifuna ukukuthumela kwi-urologist ukuba uqwalasele ukwenza i-biopsy," impendulo yakho efanelekileyo kufuneka ukuba, "Nceda undithumele umgangatho ophezulu we-3T we-MRI scan or high - umbala wenguqu Doppler ultrasound ukukhangela ukulinganisa ubukhulu be-prostate gland. "
I-scan iyakuchaza ubungakanani beprotate kwi-cubic centimeters okanye "cc." Inqanaba le-PSA linokuthi lichazwe ngokuthi "liqhelekileyo" ukuba li malunga nesishumi sesayizi yeprotate. Ngokomzekelo, i-PSA eqhelekileyo ye-prostitute gland iya kuba ngu-5. I-PSA evamile kwi-70cc prostate yi-7. I-PSA iphezulu ngokungavamile , isebenzisa umzekelo womntu one-50cc prostate, xa i- 50% ngaphezulu xabiso eliqhelekileyo elilindelekileyo le-5 , ngamanye amagama, ngaphezu kwe-7.5. (I-50% ye-5 = 2.5.) Inani eli-2.5 longezwa kwixabiso eliqhelekileyo le-5 ukuvelisa ixabiso le-PSA ngomda ophezulu oqhelekileyo wolu hlobo lwe-prostate gland eline-7.5).
Kakade ke, ezinye izinto ezingaphezulu kobukhulu beprotate zingadinga ukuba ziqwalaselwe xa zitolika i-PSA. Izifo zeprostate, iimpazamo zebhabhi kunye nomsebenzi wokwabelana ngesondo kunokubangela ukwanda kwexeshana kwinqanaba le-PSA. Isinyathelo sokuqala esinengqiqo, nangaphambi kokuba wenze i-prostate scan, ukulinda kwaye ubuyisele i-PSA ngeveki.
Ukuphakama kwexeshana kunye nokungachazwanga kwePSA kubakho lonke ixesha kwaye ngokuphindaphindiweyo babuyela emuva kwisiseko esingaphandle nongenelelo.
Kukho iingenelo ezongezelelweyo zokwenza i-prostate imaging nge-MRI multiparameter okanye umbala weDoppler ultrasound kunokuba wenze i-biopsy ye-12-core core.
- Xa indawo ekhankanya umdlavuza ophezulu, i-biopsy ejoliswe kuyo ingenziwa. Oku kuthetha ukuba kuphela iisampuli zedalane enye kuphela okanye zenze i-sampuli yesaliti endaweni yokwenza enye. Oku kunciphisa ubunzima kunye nomngcipheko wosulelo.
- Ukuba i-lesion esicatshulwayo ifunyenwe zikhetho ezimbini ziyakucingelwa: I-lesion esicangayo inokujoliswa nentsholongwane ye-needle, okanye, izigulane zinokuqwalasela nje ukujonga imeko ngokukhawuleza ngokuphindaphinda i-scan kwiinyanga ezintandathu ukuze ubone ukuba isilonda sikhula okanye sitshintsha .
- Amadoda anezilonda eziphantsi (kunye namazinga e-PSA aqhelekileyo asebenzisa inkcazo ye-PSA ichazwe ngasentla) angenza i-biopsy ngokupheleleyo kwaye aphinde ahlaziywe emva konyaka omnye.
Ukufaniswa kweprostate
Ukucatshulwa kweprostate yintuthuko emangalisayo kodwa iteknoloji intsha kwaye akuzona zonke iziko zokucinga ezikwazi ukuphumeza iziphumo ezilinganayo eziphezulu. Umgaqo-nkqubo we-PSA wokubhenca owakhankanywa kweli nqaku, usebenzisa i-scans-art-art scans njengenxalenye yokwenza i-biopsy engama-12 engundoqo, ixhomekeke kwiingcinga ezilandelayo:
- Ukucinga kuyenziwa ngezixhobo zobugcisa.
- I-scanning yenziwa ngabachwephesha abaqeqeshwe kakuhle.
- Imifanekiso efumaneka kwi-scan iguqulelwa ngama-radiologists abanamava.
- Ingcaciso ehlinzekwe ngxelo yeskripthi yenziwa yinkwenkwe yomhlaza wesibeletho.
Ukungabi nakukho nawuphi na kule mimandla kunokukwenza izigqibo ezithatyathwe kwiinkcazo ze-scan ezilahlekisayo nezingathembekiyo.
Siphelile ixesha elide ngenxa yezinto ezintle zokungena kwi-12-core coreal biopsies. Ukucatshulwa kweprostate, ukucinga ukuba kuqhutywe kakuhle, ukuchazwa ngokufanelekileyo nokuqondiswa kakuhle kukulethela ukukhululwa okude kulinde. Isinyathelo esilandelayo siya kuphuhlisa amaziko okucinga okuphezulu kunye nokuzimisela ngakumbi koogqirha ukuba bafunde malunga nokuzivumelanisa nale teknoloji entsha.
