ukwelashwa kwe-brca gene prostate cancer

Ubukhona buka a Uhlobo lwe-BRCA ukuguqulwa kwezakhi zofuzo, okuvame ukuhlotshaniswa nomdlavuza webele nowesibeletho, nakho kungadlala indima ebalulekile ekuthuthukisweni nasekwelapheni umdlavuza wendlala yesinye. Ukuqonda imithelela yalezi zinguquko kubalulekile kumasu okwelapha okuqondene nomuntu kanye nemiphumela yesiguli ethuthukisiwe. Lesi sihloko sihlola isixhumanisi phakathi Izakhi zofuzo ze-BRCA futhi umdlavuza wendlala yesinye, ukuhlolisisa ukuxilongwa, izinketho zokwelapha, kanye nocwaningo oluqhubekayo.Ukuqonda Izakhi Zofuzo ze-BRCA Nendima YazoZiyini Izakhi Zofuzo ze-BRCA1 kanye ne-BRCA2?I-BRCA1 futhi I-BRCA2 ziyizakhi zofuzo zomuntu ezikhiqiza amaprotheni anesibopho sokulungisa i-DNA eyonakele. Lawa maprotheni adlala indima ebalulekile ekugcineni ukuqina kolwazi lwethu lofuzo nokuvimbela ukukhula kwamangqamuzana okungalawuleki. Uma lezi zakhi zofuzo ziguqulwa, azikwazi ukulungisa ngokuphumelelayo umonakalo we-DNA, okwandisa ingozi yokuba nomdlavuza othile.Indlela Izinguquko ze-BRCA Ezithinta Ngayo Ingozi Yomdlavuza I-BRCA1 futhi I-BRCA2 zivame ukuhlotshaniswa nengozi eyengeziwe yomdlavuza webele nowesibeletho kwabesifazane. Kodwa-ke, lezi zinguquko ziphinde ziphakamise ingozi yezinye izinhlobo zomdlavuza, kuhlanganise umdlavuza wendlala yesinye, umdlavuza we-pancreatic, kanye ne-melanoma. Amadoda ane-a Uhlobo lwe-BRCA ukuguquka kwezakhi zofuzo kunethuba eliphezulu lokuthuthukisa ulaka umdlavuza wendlala yesinye esemncane.Izinguquko ze-BRCA kanye Nomdlavuza Wendlala Yendlala Yendlala Ingozi Eyandayo kanye Nolaka Ucwaningo lubonise ukuthi amadoda ane I-BRCA1 noma I-BRCA2 ukuguqulwa kwezakhi zofuzo kunengozi enkulu kakhulu yokuvela umdlavuza wendlala yesinye uma kuqhathaniswa namadoda angenazo lezi zinguquko. Ngaphezu kwalokho, umdlavuza wendlala yesinye emadodeni nge I-BRCA ukuguqulwa kwezakhi zofuzo kuvame ukuba nolaka, kuvame ukwethula esikhathini esizayo kanye namaphuzu aphezulu e-Gleason. I-National Cancer Institute inikeza ulwazi olwengeziwe mayelana I-BRCA izakhi zofuzo kanye nengozi yomdlavuza.Ukuhlola kanye Nokuhlolwa Kwezakhi ZofuzoNgokubona ubungozi obukhulayo, ukuhlolwa kofuzo I-BRCA1 futhi I-BRCA2 ukuguqulwa kwezakhi zofuzo kunconywa emadodeni anomlando womndeni we umdlavuza wendlala yesinye, ikakhulukazi uma umdlavuza watholakala usemncane noma uma kunomlando womdlavuza webele, we-ovary, noma we-pancreatic emndenini. Ukutholwa kusenesikhathi ngokuhlolwa, okufana nokuhlolwa kwe-PSA (i-prostate-specific antigen) nokuhlolwa kwe-digital rectal, nakho kubalulekile emadodeni asengozini enkulu. Ukuhlolwa kolibofuzo kuyatholakala nasezikhungweni ezifana nalezi I-Shandong Baofa Cancer Research Institute, lapho kunikezwa khona ukuhlolwa komuntu siqu kwengozi yomdlavuza.Izinketho Zokwelapha Umdlavuza Wendlala Yesinye Kwabesilisa abane-BRCA MutationsIzindlela Zokwelapha Ezihlosiwe: I-PARP InhibitorsI-PARP (poly ADP-ribose polymerase) inhibitors iyikilasi lezidakamizwa ezibonise imiphumela ethembisayo ekwelapheni. umdlavuza wendlala yesinye emadodeni nge I-BRCA ukuguqulwa kwezakhi zofuzo. I-PARP inhibitors isebenza ngokuvimbela i-enzyme ye-PARP, ehilelekile ekulungiseni i-DNA. Amaseli omdlavuza nge I-BRCA ukuguqulwa kwezakhi zofuzo kusengozini ikakhulukazi ekuvinjweni kwe-PARP ngoba kakade banomshini wokulungisa i-DNA osengozini. Amanye ama-PARP inhibitors avamile ahlanganisa i-olaparib (Lynparza) ne-rucaparib (Rubraca). Isebenza kanjani i-PARP Inhibitors I-BRCA izakhi zofuzo ziyaguqulwa, amangqamuzana omdlavuza athembele kwezinye izindlela zokulungisa i-DNA, kuhlanganise nendlela ye-PARP. Ngokuvimbela i-enzyme ye-PARP, i-PARP inhibitors ivimbela amangqamuzana omdlavuza ekulungiseni umonakalo we-DNA, okuholela ekufeni kweseli. Le ndlela ehlosiwe iphumelela kakhulu ku umdlavuza wendlala yesinye amaseli nge I-BRCA ukuguqulwa kwezakhi zofuzo, njengoba zingakwazi ukulungisa kahle umonakalo we-DNA ngezinye izindlela.Idatha Yesivivinyo Somtholampilo kanye Nokusebenza Okusebenzayo Izivivinyo zezokwelapha zibonise ukuphumelela kwe-PARP inhibitors ekwelapheni okuthuthukisiwe. umdlavuza wendlala yesinye emadodeni nge I-BRCA ukuguqulwa kwezakhi zofuzo. Isibonelo, uhlolo olujulile lubonise ukuthi i-olaparib ithuthukise kakhulu impilo yonke kanye nokuphila ngaphandle kokuqhubekela phambili kwe-radiographic emadodeni ane-metastatic castration-resistant. umdlavuza wendlala yesinye (mCRPC) kanye I-BRCA1 noma I-BRCA2 ukuguqulwa kwezakhi zofuzo. Imiphumela evela ocwaningweni olujulile ingatholakala ku- I-New England Journal of Medicine.Ezinye Izindlela ZokwelaphaNgenkathi ama-PARP inhibitors eyindlela yokwelapha eqondiwe, okunye okujwayelekile umdlavuza wendlala yesinye Ukwelashwa kungase kusetshenziswe emadodeni ane I-BRCA ukuguqulwa kwezakhi zofuzo. Lokhu kubandakanya: Ukuhlinzwa: I-Radical Prostatectomy (ukususwa kwe-prostate gland) kungase kube inketho yokwenziwa kwendawo umdlavuza wendlala yesinye. Ukwelapha ngemisebe: Ukwelashwa ngemisebe ye-beam yangaphandle noma i-brachytherapy (imisebe yangaphakathi) ingasetshenziswa ukukhomba nokubhubhisa amaseli omdlavuza. I-Hormone Therapy: I-Androgen deprivation therapy (ADT) ihlose ukwehlisa amazinga e-testosterone, angabambezela ukukhula kwe umdlavuza wendlala yesinye amaseli. I-Chemotherapy: Izidakamizwa ze-Chemotherapy zingase zisetshenziselwe ukwelapha okuthuthukile umdlavuza wendlala yesinye esesabalale kwezinye izingxenye zomzimba.Ikusasa Lokwelashwa Komdlavuza Wendlala Yendlala Yendlala Yendlala Yendlala Yendlala ye-cansi ye-BRCAUcwaningo Oluqhubekayo kanye Nezilingo ZomtholampiloUcwaningo luyaqhubeka ukuze kuqondwe kabanzi indima I-BRCA izinguquko ku umdlavuza wendlala yesinye kanye nokuthuthukisa amasu okwelapha amasha nasebenza ngempumelelo. Izivivinyo zemitholampilo zihlola ukusetshenziswa kwe-PARP inhibitor ngokuhambisana nezinye izindlela zokwelapha, kanye nokuphenya okuhloswe ngemishanguzo emisha kanye nezindlela zokwelapha eziqondene nomuntu.Umuthi Owenziwe Umuntu kanye Ne-Precision Oncology I-BRCA izinguquko ku umdlavuza wendlala yesinye iziguli zigqamisa ukubaluleka kwemithi yomuntu siqu kanye ne-oncology enembile. Ngokuqonda izici zofuzo zomdlavuza womuntu, odokotela bangalungisa amasu okwelapha ukuze bakhulise ukusebenza kahle futhi banciphise imiphumela engemihle. Ukuhlolwa kofuzo lwe I-BRCA nezinye izakhi zofuzo ezihlobene nomdlavuza ziya ngokuya zivame kakhulu umdlavuza wendlala yesinye ukuphathwa.Ithebula: Isifinyezo Sezinketho Zokwelashwa ze-BRCA-mutated Prostate Cancer Treatment Option Incazelo Ukufaneleka kwe-BRCA-mutated Prostate Cancer PARP Inhibitors Izidakamizwa ezivimba i-enzyme ye-PARP, evimbela ukulungiswa kwe-DNA kumaseli omdlavuza. Isebenza kahle kakhulu, ikakhulukazi ezigabeni ezithuthukile. Ukuhlinzwa Ukususwa kwe-prostate gland. Ifanele umdlavuza wendawo; ukusebenza kahle akuxhumene ngqo nesimo se-BRCA. I-Radiation Therapy Ukusetshenziswa kwemisebe enamandla amakhulu ukubulala amangqamuzana omdlavuza. Kuyasebenza, kodwa isimo se-BRCA singathonya impendulo. I-Hormone Therapy Yehlisa amazinga e-testosterone ukunciphisa ukukhula komdlavuza. Ukwelashwa okujwayelekile, ukusebenza kahle okungaxhumene ngqo nesimo se-BRCA. I-Chemotherapy Ukusetshenziswa kwezidakamizwa ukubulala amangqamuzana omdlavuza. Isetshenziswa ezigabeni ezithuthukile, isimo se-BRCA singathonya impendulo. IsiphethoUkuqonda ukuxhumana phakathi Izakhi zofuzo ze-BRCA futhi umdlavuza wendlala yesinye kubalulekile ekwenzeni ngcono ukuxilongwa, ukwelashwa, kanye nemiphumela yabantu abathintekile. Ukuhlolwa kwezakhi zofuzo, izindlela zokwelapha ezihlosiwe njenge-PARP inhibitors, nocwaningo oluqhubekayo kuvula indlela yezindlela eziqondene nawe nezisebenza ngempumelelo kakhulu zokuphatha. umdlavuza wendlala yesinye emadodeni nge I-BRCA ukuguqulwa kwezakhi zofuzo. Amadoda anomlando womndeni ka umdlavuza wendlala yesinye noma eminye imidlavuza ehlobene kufanele icabangele ukuhlolwa kofuzo futhi ixoxe ngamasu okuhlola afanelekile nabahlinzeki babo bezempilo. Ochwepheshe abazinikele ezikhungweni ezifana I-Shandong Baofa Cancer Research Institute, eyaziwa ngokwelashwa komdlavuza, banikela ngenkuthalo entuthukweni kulo mkhakha.
