PSA bvunzo: chii icho, chii icho chiri uye maitiro ekunzwisisa mhedzisiro

• Chii ichochi

• Chii chinonzi mahara PSA?
• Psa density uye nekukurumidza

PSA, inozivikanwa seProstatic Specific Antigen, ndiyo enzyme inogadzirwa nemaseru eprostate ayo kuwanda kwekusungwa kunogona kuratidza shanduko muprostate, senge prostatitis, benign prostatic hypertrophy kana kenza yeprostate, semuenzaniso.

Kuongororwa kweropa rePSA kunowanzooneswa kanokwana kamwe pagore muvarume vese vanopfuura makore makumi mana nemashanu ekuberekwa, asi inogona kushandiswa pese panenge paine fungidziro yekumwe kuita weti kana kweprostate. Iyo PSA bvunzo iri nyore uye isingarwadzi uye inoitwa murabhoritari nekunhonga diki yeropa sampuro.

Kazhinji, varume vane hutano vane huwandu hwese hwePSA pazasi pe2,5 ng / ml, vasati vasvika makore makumi matanhatu nemashanu, kana pazasi pe4.0 no / ml, pamusoro pemakore makumi matanhatu nemashanu. Iko kuwedzera kweiyo yakazara PSA yevasungwa haisi kugara ichiratidza gomarara reprostate, uye kumwezve kuyedzwa kunokosha kusimbisa kuongororwa.

Nekudaro, mune kesi yekenza yeprostate, kukosha kwePSA kunogona zvakare kugara kwakajairika uye, nekudaro, fungidziro yegomarara inofanirwa kugara ichisimbiswa nedzimwe bvunzo dzekuongorora, senge digital rectal kuongororwa, MRI uye biopsy.

Chii ichochi

Muzviitiko zvakawanda, iyo PSA bvunzo inorayirwa nachiremba kuti aongorore kuvepo kwekuvapo kwedambudziko reprostate senge:

• Kuzvimba kweprostate, inozivikanwa seprostatitis (yakaoma kana isingagumi);
• Benign prostatic hypertrophy, inozivikanwa seBPH;
• Kenza yeprostate.

Zvisinei, kukosha kwePSA kunogonawo kuwedzerwa nekuda kwehumwe hutachiona hwehutachiona, kuchengetwa kwekuvhenekera kana nekuda kwenzira dzekurapa dzichangoburwa mudunhu, senge cystoscopy, digital rectal kuongororwa, biopsy, kuvhiyiwa kweprostate kana trans-urethral resection yeprostate. Naizvozvo, zvakakosha kuti iyo mhedzisiro yekuyedzwa iongororwe nachiremba akaikumbira.

Mukuwedzera kune izvi zvinowanzoitika zvikonzero, kuwedzera zera, kuchovha bhasikoro uye kushandiswa kwemimwe mishonga, senge mahormone echirume, zvinogona kutungamira kukuwedzera kwePSA.

Maitiro ekunzwisisa bvunzo mhedzisiro

Kana murume aine huwandu hwese hwePSA hwakakura kupfuura 4.0 ng / ml, zvinokurudzirwa kudzokorora bvunzo yekusimbisa kukosha, uye kana ikachengetedzwa zvakakosha kuita mimwe miedzo yekusimbisa kuongororwa uye kuona chikonzero. Svika pakuziva mimwe bvunzo kuti uongorore prostate.

Muzviitiko zvakawanda, iyo yakakwira iyo yakazara kukosha kwePSA, gomarara reprostate rinofungidzirwa uye, nekudaro, kana kukosha kwacho kuri kukuru kudarika gumi ng / ml, mikana yekuva nekenza yeprostate iri makumi mashanu muzana. Iko kukosha kwePSA kunogona kusiyana nezera, tsika dzevanhu uye rabhoritari uko kwakaedzwa bvunzo. Muzhinji, iwo PSA mareferenzi kukosha ndeaya:

• Kusvika pamakore makumi matanhatu nemashanu: Yakazara PSA inosvika ku2,5 ng / mL;
• Pamusoro pemakore 65: Yakazara PSA inosvika ku4 ng / mL.

Varume vane PSA vanofungidzirwa zvakajairwa uye vane maqhuguru pane edhijitari rectal bvunzo vane yakanyanya njodzi yekuve nekenza yeprostate pane varume vane iyo chete yepamusoro PSA kukosha.

Kuti unyatso kuziva kana paine shanduko muprostate, svikiro rinokurudzira kuita kuyerwa kwePSA yemahara uye hukama pakati pePSA yemahara uye yakazara PSA, izvo zvakakosha kuti uonekwe nekenza yeprostate.

Chii chinonzi mahara PSA?

Kana murume aine PSA yakazara pamusoro peyakajairwa, iyo urologist inoratidza kuzadzikiswa kwemahara PSA, kunatsiridza kuferefetwa kwekenza yeprostate. Kubva pamhedzisiro yemahara uye yakazara PSA, hukama hunoitwa pakati peiyi mhedzisiro miviri kuti uone kana shanduko muprostate iri yakaipa kana yakaipa, mune iyo kesi iyo prostate biopsy inokurudzirwa.

Kana chiyero pakati pePSA yemahara uye yakazara chiri pamusoro pe15%, chiratidzo chekuti prostate yakawedzerwa iri benign, izvo zvinogona kuratidza kuti zvirwere zvinotapukira zviri kukura, zvakadai sebenign prostatic hypertrophy kana hutachiona hwehutachiona, semuenzaniso. Nekudaro, kana chiyero ichi chiri pasi pe15%, chinowanzo kuratidza kenza yeprostate, uye prostate biopsy inokurudzirwa kuti isimbise kuongororwa uye kutanga kurapwa. Nzwisisa kuti prostate biopsy inoitwa sei.

Psa density uye nekukurumidza

Iyo urologist inogona zvakare kuongorora kuwanda uye kumhanya kwePSA, iyo yakanyanya kuwanda kwePSA, kwakanyanya kufungidzira kwekuvapo kwekenza yeprostate uye, mune iyo kukosha kwePSA kumhanya, inowedzera neanopfuura 0.75 ng / ml pa gore kana kuwedzera nekukurumidza zvakanyanya zvakakosha kudzokorora bvunzo, nekuti zvinogona kuratidza cancer.
