\nCercet\u0103torii de la Stanford Medicine au dezvoltat un program revolu\u0163ionar de inteligen\u0163\u0103 artificial\u0103 care poate prezice activitatea a mii de gene din tumori analiz\u00e2nd doar imaginile obi\u015fnuite ale biopsiilor, f\u0103r\u0103 a mai fi nevoie de teste genetice costisitoare care pot dura s\u0103pt\u0103m\u00e2ni \u00eentregi.<\/p>\n
\nProgramul, numit SEQUOIA, func\u0163ioneaz\u0103 asemenea unui \u201etranslator” \u00eentre imaginea tumorii v\u0103zut\u0103 la microscop \u015fi activitatea genelor din celulele canceroase.<\/p>\n
\nAcesta poate analiza imagini standard de biopsie, colorate prin metoda clasic\u0103 folosit\u0103 \u00een toate spitalele, prezice comportamentul a peste 15.000 de gene diferite, atinge o precizie de peste 80% pentru anumite tipuri de cancer, oferi rezultate imediate, fa\u0163\u0103 de s\u0103pt\u0103m\u00e2nile necesare testelor genetice clasice \u015fi economisi mii de dolari per pacient, relateaz\u0103 Nature Communications.<\/p>\n
\n\u201eAcest tip de software ar putea identifica rapid semn\u0103turile genetice \u00een tumorile pacien\u0163ilor, acceler\u00e2nd deciziile medicale \u015fi economisind sume importante pentru sistemul de s\u0103n\u0103tate”, explic\u0103 profesorul Olivier Gevaert, coordonatorul cercet\u0103rii.<\/p>\n
\nPentru a crea acest program, echipa a folosit 7.584 de biopsii din 16 tipuri diferite de cancer, date despre genele active \u00een aceste tumori \u015fi informa\u0163ii despre celule s\u0103n\u0103toase pentru compara\u0163ie.<\/p>\n
\nProgramul s-a dovedit deosebit de eficient \u00een cazul cancerului de s\u00e2n, unde poate \u00eenlocui teste genetice costisitoare precum MammaPrint, care analizeaz\u0103 70 de gene pentru a prezice riscul de reapari\u0163ie a cancerului. Testele au ar\u0103tat c\u0103 pacientele identificate ca av\u00e2nd risc ridicat de c\u0103tre SEQUOIA au avut \u00eentr-adev\u0103r rate mai mari de recidiv\u0103 \u015fi timp mai scurt p\u00e2n\u0103 la reapari\u0163ia bolii.<\/p>\n
\n\u201eAm demonstrat c\u00e2t de util este pentru cancerul de s\u00e2n, iar acum \u00eel putem folosi pentru toate tipurile de cancer. Este o surs\u0103 complet nou\u0103 de informa\u0163ii pe care nu o aveam p\u00e2n\u0103 acum”, spune profesorul Gevaert.<\/p>\n
\nDe\u015fi programul nu poate fi \u00eenc\u0103 folosit \u00een spitale – trebuie s\u0103 treac\u0103 prin studii clinice \u015fi s\u0103 primeasc\u0103 aprobarea FDA – cercet\u0103torii continu\u0103 s\u0103-l \u00eembun\u0103t\u0103\u0163easc\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
