[Organoids from pancreatic ductal adenocarcinoma].


Pancreatic ductal adenocarcinoma (PDAC) is a rapidly evolving and most frequently fatal disease. Despite the enormous progress in understanding the mechanisms related to PDAC pathogenesis, the impact on patient management has not yet been possible. Pancreatic organoids can be generated from small amounts of tissue. One of the most promising applications of organoids is that they can serve as a platform for selecting the right drugs for each patient. This approach has the potential to identify individual therapeutic vulnerabilities by allowing the personalization of treatments. However, these analyzes require several weeks before obtaining enough organoids from the same individual, to carry out the tests with several drugs, and to analyze the results, which limits its use in current clinical practice for the patients with a PDAC, whose it must be remembered that half die within 6 months of diagnosis. To overcome this obstacle, we assessed the ability of transcriptomic molecular signatures to identify patients with a particular sensitivity profile to a given treatment. The approaches based on transcriptomic profiling have the enormous advantage of using very little biological material and thus significantly reducing the time to arrive at the selection of more effective drugs to each patient.
