Njengoko siqhubela phambili, ugxininiso luya kuhlala ekuluphuculeni olu nyango, ukwandisa ufikelelo, kunye nokuqhubeka nokusukela ngokungapheliyo kweziphumo ezingcono. Intsebenziswano phakathi kwabaphandi, oogqirha, kunye neenkampani zamachiza ziye zavelisa iziqhamo ezazingenakucingelwa kwiminyaka embalwa edlulileyo. Kwizigulane kunye neentsapho ezichaphazelekayo yi-SCLC, i-2026 ibonisa ukuqala kwexesha elitsha apho ukusinda akusayi kulinganiswa kwiinyanga nje, kodwa kwiminyaka egcwele umgangatho kunye nokwenzeka.

• Okubalulekileyo kokuthatha: Ukudibanisa i-Iza-bren kunye ne-PD-1 inhibitors ibeke umgangatho omtsha wegolide kunye ne-85.7% yezinga lokuphila ngonyaka omnye.
• Ujongo lwekamva: Ukudityaniswa kwee-T-cell ezibandakanya i-Tarlatamab iqinisekisa umbhobho oqinileyo wokhetho lwezifo ezibuyelayo.
• Impembelelo yesigulana: Ukutshintsha kude kwi-chemotherapy enetyhefu kuphucula umgangatho wobomi ngelixa kusandiswa ukusinda.

Uhambo olungaphambili lubandakanya ukuqapha okuqhubekayo, uphando, kunye nokulungelelanisa, kodwa isiseko esibekwe ngo-2026 sibonelela ngeqonga eliqinileyo lempumelelo yexesha elizayo. Umlo ochasene nenqanaba elibanzi lomhlaza wemiphunga weseli encinci ungene kwinqanaba apho uloyiso luya lufikeleleka.
