Ngokwengxelo yamva nje yomhlaza wehlabathi, umhlaza wemiphunga uyaqhubeka nokuba ngunobangela ophambili wokufa okunxulumene nomhlaza kwihlabathi liphela, ubanga i-18.7% yazo zonke ezi zinto zibulalayo ngo-2022. Uninzi lwala matyala yiNon-Small Cell Lung Cancer (NSCLC). Nangona ukuxhomekeka kwangaphambili kwi-chemotherapy kwisifo esiphucukileyo kunike inzuzo encinci, indlela yokuphila itshintshile kakhulu.
Ukufunyanwa kwee-biomarkers ezibalulekileyo, ezifana ne-EGFR, i-ALK, kunye ne-ROS1, kuye kwaguqula unyango, kwalususa kwindlela enye yokwenza yonke into ukuya kwindlela echanekileyo ejolise kwiindlela ezizodwa zofuzo zomhlaza wesigulane ngasinye.
Nangona kunjalo, impumelelo yolu nyango luguqukayo ixhomekeke ngokupheleleyo kuvavanyo lwemfuza oluchanekileyo noluthembekileyo ukuze kuchongwe injongo efanelekileyo yesigulana esifanelekileyo.
Iimpawu zeBiomarkers ezibalulekileyo: i-EGFR, i-ALK, i-ROS1, kunye ne-KRAS
Iibhayomarker ezine zimi njengeentsika ekuxilongweni kwe-molecular ye-NSCLC, zikhokela izigqibo zonyango zomgca wokuqala:
-I-EGFR:Eyona nguqu ixhaphakileyo enokwenzeka, ingakumbi kubantu baseAsia, abangabasetyhini, nabangatshayiyo. I-EGFR tyrosine kinase inhibitors (TKIs) efana ne-Osimertinib iphucule kakhulu iziphumo zezigulane.
-I-ALK:"Utshintsho lwedayimani," lufumaneka kwi-5-8% yeemeko ze-NSCLC. Izigulane ezine-ALK fusion-positive zihlala zisabela kakhulu kwi-ALK inhibitors, ziphumelela ekusindeni ixesha elide.
-I-ROS1:Njengoko isabelana ngokufana kwesakhiwo ne-ALK, le "gugu inqabileyo" iyenzeka kwi-1-2% yezigulane ze-NSCLC. Iindlela zonyango ezisebenzayo ziyafumaneka, nto leyo eyenza ukuba ukufunyaniswa kwayo kube yinto ebalulekileyo.
-I-KRAS:Ngokwembali, utshintsho lwe-KRAS luqhelekile. Ukuvunywa kwakutshanje kwe-KRAS G12C inhibitors kutshintshe le biomarker ukusuka kwi-prognostic marker ukuya kwi-target enokwenzeka, nto leyo eguqula ukhathalelo lwale nxalenye yesigulane.
Ipotifoliyo ye-MMT: Yenzelwe Ukuqiniseka Ngokuxilonga
Ukuze kuhlangatyezwane nesidingo esingxamisekileyo sokuchongwa kwe-biomarker ngokuchanekileyo, i-MMT inikezela ngepotifoliyo ye-CE-IVD ephawulwe ngexesha langempelaIikiti zokuchonga i-PCR, nganye yenziwe ngetekhnoloji yanamhlanje ukuqinisekisa ukuzithemba kokuxilonga.
