Genetic, Microenvironmental, and Immunological Factors in Unresectable Pancreatic Ductal Adenocarcinoma

Catholic University of the Sacred Heart250 enrolled

Overview

Pancreatic ductal adenocarcinoma (PDAC) complexity, where genetic, stromal, and immunological factors all interact with each other, is responsible for the overall poor response of PDAC to chemotherapeutic agents, making this a lethal disease. The investigators hypothesize that: (i) dissection of genetic, stromal, and immunological factors on endoscopic ultrasound fine needle biopsy (EUS-FNB) tissue samples from unresectable PDAC patients' will allow to determine prognostic factors in this patient population; (ii) treatment response and acquisition of tumor chemotherapy resistance could be related to genetic heterogeneity between the primary and metastatic sites and alteration of the molecular profile under drug' selection pressure.

Outcomes

Primary Outcomes

Progression-free-survival (PFS)

To assess the impact of comprehensive genetic, stromal, and immunological factors on PFS defined as the time from the date of trial entry until disease progression or relapse.

Time frame: From date of enrollment assessed until death or up to 2 years

Overall survival

To assess the impact of comprehensive genetic, stromal, and immunological factors on Overall survival defined as the length of time (in days) between the treatment date and the date of death.
