Pharmacotyping of Patient-derived Pancreatic Cancer Organoids From Endoscopic Ultrasound-guided Biopsy as a Tool for Predicting Oncological Response
EUS-FNB samples will be used for organoid cultures, which will be co-cultured with cancer associated fibroblasts derived from the surrounding stroma of the lesion. The organoid cultures will be used for pharmacotyping using relevant chemotherapeutic agents used in the clinic, and the organoid's response compared with the patient's response.
