Zikuwoneka kuti tili ndi chilakolako cha dziko la ma biopsies. Amuna mamiliyoni amatsatiridwa chaka chilichonse. Anthu mazana awiri a iwo adzapezeka ndi khansa ya prostate ndipo pafupifupi theka la izi ndi matenda otsika kwambiri, omwe angayang'ane mosamala popanda chithandizo chamankhwala. Ngakhale zili choncho, oposa theka la amunawa omwe ali ndi zochepa zoopsa adzapulumutsidwa mwamsanga.
N'zomvetsa chisoni kuti mantha osayenerera amachokera ku mawu osokoneza "khansa" amachititsa amuna ambiri kuti achitepo kanthu mwamsanga.
Popeza kuti matenda akuti "khansa" amaonetsa kuti akudwala kwambiri, akatswiri ena amati tangosiya kuyeza kwa PSA kwathunthu. Mwanjira imeneyo, ngati amuna sapezeka kuti sangapezedwe ku chipatala choopsa chomwe chimapangitsa aliyense kuti achuluke mwamsanga. Komabe, kuyankhula mobwerezabwereza, kubwereranso ntchito pa PSA pofuna kuyesera sikudzachitika. Odwala ndi madokotala onse safuna kutaya chidziwitso chimene PSA ikuyesa, yopanda ungwiro.
Kunena zoona, anthu anzeru akuyamba kuzindikira kuti kuyesa kwa PSA payekha si vuto lenileni. Vuto ndilokuti madokotala ndi odwala amakhumudwa kwambiri ndi zomwe PSA imapereka. PSA ndi chizindikiro chosayenerera chenicheni chomwe chingakwezeke chifukwa cha zifukwa zambiri zosagwirizana ndi chidziwitso monga kupatulira kwa prostate, kugonana kumeneku kapena kutupa (prostatitis).
Njira yothetsera makampani ochipatala omwe amagwiritsa ntchito mankhwala odyera, sikuti nthawi zambiri amafufuza PSA, koma amadokotala amachititsa kuti pang'onopang'ono kufulumizitsa kuthamangira pang'onopang'ono pokhapokha ngati pali chizindikiro chochepa cha PSA. Tsopano tikudziwa kuti palibe phindu pozindikira kuti pali vuto lililonse la khansa ya prostate monga ambiri omwe alibe vuto lililonse.
Ndizopindulitsa kwambiri kupulumutsa anthu zidziwitso zopanda phindu kuti ali ndi kansa ya prostate yoopsa yosaopsa.
Choncho pali malo apakati pakati pa chiwonetsero cha PSA iliyonse ndi kukweza PSA kuyesa ndi chiwonongeko chonse? Musanasankhe kuchita chiwopsezo, prostate gland iyenere kuyesedwa ndi sewero la ultrasound kuti liwone ngati likukula modabwitsa. Ngati kuchuluka kwa PSA kukwera ndikulingana ndi kukula kwa prostate, ndiye kuti PSA kukwera kungawonongeke chifukwa chabvuto. M'malo moyendetsa pang'onopang'ono, kuyesa kwa PSA kwina ndi mpikisano wa OPKO 4K kungasonyezedwe. Ubwino wa PSA OPKO 4Kscore wokhazikika pa PSA ndikuti umapereka chiwonetsero cha chiopsezo chokhala ndi kansa ya prostate yapamwamba, yomwe imakhala yotsiriza kwambiri.
Ngati mawonekedwe a OPKO 4Kscore ndi PSA ali othandizira, ndiye kuyang'anitsitsa kwina ndi mawonekedwe ena amapereka inshuwalansi yowonjezereka kuti asathenso kulandira khansa yaukali. Masiku ano 3-Tesla Multiparametric MRI (MP-MRI) ndi mtundu wotchuka kwambiri wa Doppler ultrasound, ngakhale kuti si wangwiro, ndi njira zolondola zodziŵira khansa yaukali.
Kotero mwachidule, chidziwitso chokhazikika chiyenera kukhala chinthu chomaliza kwa amuna omwe ali ndi mapepala apamwamba a PSA omwe sangathe kufotokozedwa ndi matenda a prostate, zolakwika za labotolo kapena zochitika zogonana zatsopano.
Nazi zizindikiro zina zoti biopsy ingafunike:
1. Kuphulika kwa PSA kupitirira kufanana ndi kukula kwa chigoba chawo
2. OPKO 4Kscore yomwe ikuwonetsa mwayi waukulu wa kansa ya prostate yapamwamba
3. Kusamvetsetsana kumamveka pamayendedwe a digito
4. Kufufuza kufotokozera kuganizira za khansa yamphamvu
PSA ndi chida chodabwitsa chimene tadalira kuti tipeze kansa ya prostate kuyambira kumayambiriro kwa zaka za m'ma 1990. Izi zasintha kasamalidwe ka khansara ya prostate m'zaka 20 zapitazo. Komabe, mtengo wakhala wochulukitsidwa kwambiri wa amuna pafupifupi 100,000 pachaka.
PSA yapamwamba, m'malo moyambitsa chidziwitso mwamsanga, iyenera kuyambitsa kufufuza kwina monga tafotokozera pamwambapa. Kuthamangira ku chidziwitso chifukwa chakuti PSA ikukwera nthawi zambiri kumayambitsa chithandizo chopanda pake chofunikira ndi zotsatira zowononga moyo wonse.
