  "abstract": "Despite advances in systemic therapies for patients with (locally) advanced stage lung cancer, response rates remain poor, underscoring the urgent need for predictive models to guide therapy selection. Patient-derived ex vivo models are promising, however, their clinical utility is restricted by the need for surgical biopsies, low establishment rates, and culture durations exceeding the clinically-relevant therapeutic decision-making window. Here, we developed and clinically validated a rapid, high-throughput ex vivo 3D tumor replica platform that enables functional drug testing from small diagnostic biopsies. In this prospective multicenter cohort study of 129 treatment-naïve lung cancer patients, tumor replicas were successfully established in 65% of biopsies. These cultures retained their original morphological, genetic, and immunophenotypic features. Ex vivo drug responses to chemotherapy and targeted agents were generated within a median of 12 days from biopsy acquisition. The ex vivo drug responses were in concordance with the treatment responses in patient-derived xenografts and lung cancer patients. In the clinical study, the ex vivo platform demonstrated a sensitivity of 73% and a positive predictive value of 92%. External validation confirmed the feasibility and reproducibility of the platform. In conclusion, this platform enables rapid patient-specific drug response assessment from routine biopsies within a clinically relevant time-frame.",
