5、s Real-world PFS and OS by KaplanMeier and Cox regression show no clear survival advantage across regimens in real-world practice.Findings underscore clinical equipoise and justify randomized phase trials PAPMET2(NCT05411081),SAMETA(NCT05043090),and STELLAR-304(NCT05678673).Takeaway message:Despite enthusiasm for IO and METi combinations,definitive evidence is lacking.
