Abstract:
Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers, with chemotherapy as the mainstay but highly variable efficacy and toxicity. Current regimens, such as FOLFIRINOX and gemcitabine-based combinations, are selected empirically without validated biomarkers to guide choice. Several strategies have been explored to personalize therapy. Patient-derived organoids and molecular classifiers such as PurIST have improved biological understanding but have limited clinical applicability. More recently, predictive transcriptomic signatures have emerged as practical tools. GemPred identifies patients likely to benefit from adjuvant gemcitabine; GemCore, validated in both resected and metastatic tumors, is compatible with small biopsies; and Pancreas-View integrates multiple drug-specific predictors, including for all FOLFIRINOX components and gemcitabine, enhanced by AI. These approaches, retrospectively validated in large cohorts and clinical trials, consistently link predicted sensitivity with improved survival. Beyond regimen selection, signatures enable treatment de-escalation, optimize first-line choices, and identify multidrug-resistant tumors. Ongoing prospective trials will establish their feasibility, supporting transcriptomic profiling as a step toward precision chemotherapy in PDAC.
Insights
Predictive transcriptomic signatures offer personalized chemotherapy for pancreatic cancer. These tools guide treatment selection, improving patient outcomes and enabling de-escalation for better precision medicine in pancreatic ductal adenocarcinoma (PDAC).
Area of Science:
- Oncology
- Genomics
- Translational Medicine
Background:
- Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer with chemotherapy as the primary treatment.
- Current chemotherapy regimens (e.g., FOLFIRINOX, gemcitabine) are chosen empirically, lacking biomarkers for personalized selection.
- Existing personalization strategies like organoids and molecular classifiers have limited clinical utility.
Purpose of the Study:
- To evaluate the clinical applicability of predictive transcriptomic signatures for guiding chemotherapy selection in PDAC.
- To assess the role of these signatures in optimizing treatment strategies and improving patient survival.
- To explore the potential of transcriptomic profiling for precision chemotherapy in PDAC.
Main Methods:
- Development and validation of predictive transcriptomic signatures (e.g., GemPred, GemCore, Pancreas-View).
- Integration of AI and multi-drug predictors within signatures.
- Retrospective validation in large patient cohorts and clinical trials.
Main Results:
- Transcriptomic signatures consistently predict patient response to specific chemotherapies (gemcitabine, FOLFIRINOX components).
- Predicted drug sensitivity correlates with improved survival outcomes.
- Signatures facilitate treatment de-escalation, optimize first-line therapy choices, and identify resistant tumors.
Conclusions:
- Predictive transcriptomic signatures are practical tools for personalizing PDAC chemotherapy.
- These signatures support precision medicine by enabling informed treatment selection and de-escalation.
- Ongoing trials will confirm the feasibility of transcriptomic profiling for precision chemotherapy in PDAC.
