Abstract

BACKGROUND AND AIMS: Patient-Derived Tumor Organoids (PDTOs) is a promising new disease model in pancreatic cancer for use in personalized medicine, but overall success rate (SR) of establishing these cultures from endoscopic ultrasound-guided biopsies is unknown.

METHODS: We searched relevant databases publications reporting SR of PDTO establishment from pancreatic cancer. The primary outcome was SR stratified on tissue acquisition method (EUS-guided biopsies, percutaneous biopsies, and surgical specimens).

RESULTS: We identified 24 studies including 1,053 attempts at establishing PDTOs. Overall SR was 63% (95% CI: 54%-72%). Pooled SR of PDTO establishment from EUS-guided biopsies, percutaneous biopsies, and surgical specimens were 60% (95% CI: 43-76%), 36% (95% CI: 14-61%) and 62% (95% CI: 48-75%), respectively and did not differ significantly (p = 0.1975).

CONCLUSION: The SR of PDTO establishment from EUS-guided biopsies is comparable to surgical specimens. Both techniques are suitable for tissue acquisition for PDTOs in clinical and research settings.
