WASHINGTON – Americk\u00ed vedci predstavili technol\u00f3giu, ktor\u00e1 by v bud\u00facnosti mohla v\u00fdrazne zmeni\u0165 diagnostiku rakoviny. Nov\u00fd krvn\u00fd test m\u00e1 pod\u013ea v\u00fdskumn\u00edkov zachyti\u0165 n\u00e1dorov\u00e9 ochorenia u\u017e v ran\u00fdch \u0161t\u00e1di\u00e1ch a pacienti by si ho raz mohli urobi\u0165 aj doma bez n\u00e1v\u0161tevy lek\u00e1ra. Odborn\u00edci v\u0161ak z\u00e1rove\u0148 upozor\u0148uj\u00fa na mo\u017en\u00e9 rizik\u00e1.<\/p>\n

\t\t\t\tSta\u010di\u0165 by malo nieko\u013eko kvapiek krvi<\/p>\n

V\u00fdskumn\u00edci z Kalifornskej univerzity pracuj\u00fa na teste, ktor\u00fd m\u00e1 z malej vzorky krvi odhali\u0165 pr\u00edtomnos\u0165 rakoviny e\u0161te predt\u00fdm, ne\u017e sa objavia prv\u00e9 pr\u00edznaky. Pr\u00e1ve skor\u00e9 zachytenie ochorenia v\u00fdrazne zvy\u0161uje \u0161ance pacientov na \u00faspe\u0161n\u00fa lie\u010dbu.<\/p>\n

Vedci sa pri v\u00fdvoji zamerali na fragmenty DNA, ktor\u00e9 bunky prirodzene uvo\u013e\u0148uj\u00fa do krvn\u00e9ho obehu. Tie pod\u013ea nich dok\u00e1\u017eu prezradi\u0165, \u010di sa v tele neza\u010d\u00edna rozv\u00edja\u0165 v\u00e1\u017eny zdravotn\u00fd probl\u00e9m.<\/p>\n

\u201eBunky neust\u00e1le vyp\u00fa\u0161\u0165aj\u00fa DNA do krvi a tieto fragmenty poskytuj\u00fa inform\u00e1cie o stave jednotliv\u00fdch org\u00e1nov. Potrebovali sme n\u00e1js\u0165 sp\u00f4sob, ako rozpozna\u0165 tie po\u0161koden\u00e9,\u201c vysvetlila hlavn\u00e1 autorka \u0161t\u00fadie a lek\u00e1rka Jasmine Zhou.<\/p>\n

Pod\u013ea inform\u00e1ci\u00ed, ktor\u00e9 zverejnil port\u00e1l TN.cz<\/a>, by sa cena testu v bud\u00facnosti mohla pohybova\u0165 pribli\u017ene na \u00farovni 400 \u010desk\u00fdch kor\u00fan (pribli\u017ene 16 eur). Amb\u00edciou vedcov je, aby bol vo\u013ene dostupn\u00fd v lek\u00e1r\u0148ach a \u013eudia si ho mohli vykona\u0165 sami doma.<\/p>\n

V\u00fdsledky vyzeraj\u00fa s\u013eubne ale nie bez probl\u00e9mov<\/p>\n

Prv\u00e9 testovania priniesli pod\u013ea v\u00fdskumn\u00edkov ve\u013emi povzbudiv\u00e9 v\u00fdsledky. \u00daspe\u0161nos\u0165 diagnostiky mala v niektor\u00fdch pr\u00edpadoch dosiahnu\u0165 a\u017e 98 percent.<\/p>\n

Nie pri v\u0161etk\u00fdch druhoch n\u00e1dorov v\u0161ak bola presnos\u0165 rovnak\u00e1. Pri niektor\u00fdch typoch rakoviny sa \u00faspe\u0161nos\u0165 pohybovala len okolo 60 percent, \u010do pod\u013ea odborn\u00edkov predstavuje v\u00e1\u017eny probl\u00e9m.<\/p>\n

Psychol\u00f3g a prim\u00e1r Oddelenia klinickej psychol\u00f3gie Vojenskej nemocnice Ji\u0159\u00ed Bran\u010d\u00edk upozornil najm\u00e4 na riziko takzvan\u00fdch falo\u0161ne pozit\u00edvnych v\u00fdsledkov.<\/p>\n

\u201eTest m\u00f4\u017ee \u010dloveku nespr\u00e1vne nazna\u010di\u0165 v\u00e1\u017ene ochorenie. Tak\u00e1 situ\u00e1cia potom dok\u00e1\u017ee vyvola\u0165 ve\u013emi siln\u00fd stres, \u00fazkos\u0165 aj psychick\u00fd tlak,\u201c varoval odborn\u00edk.<\/p>\n

Pozit\u00edvny v\u00fdsledok e\u0161te nemus\u00ed znamena\u0165 rakovinu<\/p>\n

Lek\u00e1ri z\u00e1rove\u0148 zd\u00f4raz\u0148uj\u00fa, \u017ee dom\u00e1ci test by v \u017eiadnom pr\u00edpade nemohol nahradi\u0165 odborn\u00e9 vy\u0161etrenie v nemocnici.<\/p>\n

Prednosta Kliniky hepatogastroenterol\u00f3gie IKEM Tom\u00e1\u0161 Hucl pripomenul, \u017ee v\u00fdsledok samotestu by sl\u00fa\u017eil iba ako orienta\u010dn\u00fd sign\u00e1l.<\/p>\n

\u201eAk by \u010dloveku vy\u0161iel pozit\u00edvny alebo negat\u00edvny v\u00fdsledok doma, e\u0161te by to automaticky nepotvrdzovalo diagn\u00f3zu. Pacient by aj tak musel absolvova\u0165 \u010fal\u0161ie vy\u0161etrenia, ktor\u00e9 by ochorenie definit\u00edvne potvrdili alebo vyvr\u00e1tili,\u201c vysvetlil Hucl.<\/p>\n

Vedci hovoria aj o \u010fal\u0161om vyu\u017eit\u00ed<\/p>\n

Hoci technol\u00f3gia vzbudzuje ve\u013ek\u00e9 o\u010dak\u00e1vania, do lek\u00e1rn\u00ed sa pod\u013ea odborn\u00edkov tak skoro nedostane. V\u00fdvoj\u00e1ri prizn\u00e1vaj\u00fa, \u017ee potrebuj\u00fa e\u0161te nieko\u013eko rokov na \u010fal\u0161ie testovanie a zlep\u0161ovanie presnosti.<\/p>\n

Do bud\u00facnosti v\u0161ak vedci veria, \u017ee podobn\u00e9 krvn\u00e9 testy by nemuseli sl\u00fa\u017ei\u0165 len na odha\u013eovanie rakoviny. Pom\u00f4c\u0165 by mohli aj pri v\u010dasnom zachyten\u00ed zlyh\u00e1vania org\u00e1nov alebo in\u00fdch v\u00e1\u017enych ochoren\u00ed.<\/p>\n","protected":false},"excerpt":{"rendered":"WASHINGTON – Americk\u00ed vedci predstavili technol\u00f3giu, ktor\u00e1 by v bud\u00facnosti mohla v\u00fdrazne zmeni\u0165 diagnostiku rakoviny.
