Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The PRECEPT study (PREdiction of Chemotherapy Effect in Pancreatic Cancer Treatment) aims to identify and validate microRNA (miRNA)-based biomarkers from pre-treatment plasma that can predict therapeutic response to neoadjuvant chemotherapy in patients with resectable or borderline resectable PDAC. Specifically, the study focuses on two standard regimens: FOLFIRINOX and gemcitabine plus nab-paclitaxel (GEM-NABP).
This is a retrospective, non-interventional, observational study using archived plasma samples collected before the initiation of NACT. Exosomal miRNA sequencing (small RNA-seq) has been performed to identify candidate predictive miRNAs. These candidates will be validated using quantitative reverse transcription PCR (qRT-PCR) in an independent patient cohort. The association between miRNA expression levels and pathologic response (CAP grade or tumor regression score) will be analyzed. Additionally, correlations with overall survival (OS) and recurrence-free survival (RFS) will be explored.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Training Cohort - NAC Responder Group
PDAC patients treated with neoadjuvant chemotherapy (FOLFIRINOX or gemcitabine plus nab-paclitaxel) who achieved CR, PR, or SD responses.
Candidate microRNAs identified in the Discovery cohort were validated using qRT-PCR (PRECEPT assay).
Responder group data were used to train and optimize the predictive miRNA panel.
PRECEPT assay (qRT-PCR validation)
Quantitative reverse transcription PCR (qRT-PCR)-based validation assay performed on pre-treatment plasma samples in the Training and Validation cohorts. Candidate microRNAs identified in the Discovery cohort by small RNA sequencing were tested using the PRECEPT assay to develop and validate a predictive miRNA panel for neoadjuvant chemotherapy response.
Training Cohort - NAC Non-Responder Group
PDAC patients who received neoadjuvant chemotherapy but exhibited progressive disease (PD).
Plasma miRNA expression was measured using the PRECEPT assay and compared with responders to refine the predictive model for chemotherapy response.
PRECEPT assay (qRT-PCR validation)
Quantitative reverse transcription PCR (qRT-PCR)-based validation assay performed on pre-treatment plasma samples in the Training and Validation cohorts. Candidate microRNAs identified in the Discovery cohort by small RNA sequencing were tested using the PRECEPT assay to develop and validate a predictive miRNA panel for neoadjuvant chemotherapy response.
Validation Cohort - NAC Responder Group
A separate validation cohort of PDAC patients treated with neoadjuvant chemotherapy who achieved CR, PR, or SD.
The established PRECEPT miRNA panel (qRT-PCR) was applied to evaluate predictive accuracy in this independent responder group.
PRECEPT assay (qRT-PCR validation)
Quantitative reverse transcription PCR (qRT-PCR)-based validation assay performed on pre-treatment plasma samples in the Training and Validation cohorts. Candidate microRNAs identified in the Discovery cohort by small RNA sequencing were tested using the PRECEPT assay to develop and validate a predictive miRNA panel for neoadjuvant chemotherapy response.
Validation Cohort - NAC Non-Responder Group
Independent PDAC patients who received neoadjuvant chemotherapy and demonstrated progressive disease (PD).
This cohort was used to confirm the predictive performance and robustness of the PRECEPT miRNA assay compared with responders.

Quantitative reverse transcription PCR (qRT-PCR)-based validation assay performed on pre-treatment plasma samples in the Training and Validation cohorts. Candidate microRNAs identified in the Discovery cohort by small RNA sequencing were tested using the PRECEPT assay to develop and validate a predictive miRNA panel for neoadjuvant chemotherapy response.
Discovery Cohort - NAC Non-Responder Group
Patients with resectable or borderline resectable PDAC who received neoadjuvant chemotherapy but demonstrated progressive disease (PD) on radiologic or pathologic evaluation.
Pre-treatment plasma samples from these patients were analyzed in parallel by small RNA sequencing to identify differential miRNA expression compared with responders.
Small RNA sequencing
High-throughput small RNA sequencing performed on pre-treatment plasma samples from PDAC patients in the Discovery cohort to identify candidate microRNAs associated with neoadjuvant chemotherapy response. Sequencing data were analyzed to detect differentially expressed miRNAs between responder (CR + PR + SD) and non-responder (PD) groups.
Discovery Cohort - NAC Responder Group
Patients with resectable or borderline resectable pancreatic ductal adenocarcinoma (PDAC) who received neoadjuvant chemotherapy (FOLFIRINOX or gemcitabine plus nab-paclitaxel) and achieved a clinical or pathological response.
Responders were defined as patients showing complete response (CR), partial response (PR), or stable disease (SD) according to radiologic or pathologic assessment after NACT.
Pre-treatment plasma samples from these patients were analyzed by small RNA sequencing to identify microRNAs associated with favorable chemotherapy response.
Small RNA sequencing
High-throughput small RNA sequencing performed on pre-treatment plasma samples from PDAC patients in the Discovery cohort to identify candidate microRNAs associated with neoadjuvant chemotherapy response. Sequencing data were analyzed to detect differentially expressed miRNAs between responder (CR + PR + SD) and non-responder (PD) groups.
