P2.06-043 - 3-Dimensional High Throughput Multi-Drug Screening Using Patient-Derived Tumor Cells (PDC) Established from Surgical Specimens of NSCLC (ID 5942)
14:30 - 14:30 | Author(s): J. Lee
- Abstract
Background:
To investigate the clinical applicability of the high throughput screening (HTS) using patient-derived tumor cells (PDC) which were established from patients with non-small cell lung cancer undergoing surgery.
Methods:
PDCs were isolated and cultured from surgical specimen from NSCLC at Samsung Medical Center. We performed the HTS for 24 drugs (23 targeted agents and 1 positive control drug) with a micropillar/microwell chip platform using PDCs. Scanned images of the live cells were obtained using an optical fluorescence. With 6 dosages per drug in 7 replicates, the dose response curves and corresponding IC~50~ values were calculated from the scanned images.
Results:
From October 2015 to February 2016, 15 samples from patients with non-small cell lung cancer were collected. PDCs were successfully established in 12 (80%) patients, and nine of 12 cases were successfully cultured in 3-d suitable for 23-drug HTS platform. Three PDCs demonstrated a sensitivity to Neratinib (HER-2/EGFR inhibitor). These PDCs are currently being profiled to elucidate the underlying molecular mechanisms for neratinib sensitivity.
Conclusion:
Differential chemosensitivity were observed which suggests that this HTS platform based on 3D culture with micropillar/microwell chips and PDC model could potentially provide a preclinical tool for predicting the efficacy of targeted agents in lung cancer.
