PIES Score Calculator: Pancreatic Cancer Subtype from ctDNA Epigenomics
PIES Score Calculator: Pancreatic Cancer Subtype from ctDNA Epigenomics
PIES (Pancreatic Integrated Epigenomic Score) can determine whether a patient's pancreatic cancer is classical or basal-like — predicting treatment response — from a blood draw, without biopsy.
Build an open-source implementation of the PIES scoring pipeline that takes cfDNA epigenomic profiling data as input (from standard liquid biopsy platforms) and outputs a PIES score with subtype classification and confidence interval. The tool would be designed to run in a standard bioinformatics environment (Nextflow or Snakemake pipeline) and output a clinical-grade report.
The pipeline would implement the published PIES methodology — integrating circulating histone modification and DNA methylation signals — with clear documentation of each step, QC thresholds, and interpretation guidelines. A companion web calculator for manual score entry (for clinicians reviewing published PIES values) would lower the barrier further.
Beyond the tool itself, the project could include a curated public dataset of PIES scores from the paper's multi-institutional cohort (if authors share data), enabling benchmark comparisons and validation by other labs. This is the kind of reference implementation that accelerates clinical translation — without it, PIES risks staying a research curiosity rather than becoming a clinical test.
Who Is This For?
Pancreatic cancer researchers, clinical molecular pathologists, bioinformaticians at cancer centers, and liquid biopsy platform developers.
Skills & Tools Needed
- Bioinformatics pipeline development (Nextflow or Snakemake)
- Epigenomics data processing (bismark for methylation, ChIP-seq/CUT&TAG for histone marks)
- R or Python for score computation and statistical modeling
- Clinical report generation (R Markdown, Quarto, or ReportLab)
- Understanding of PDAC biology and subtype classification
Feasibility
medium — The methodology is published and the data types are standard, but epigenomics pipeline development requires specialized expertise and access to cfDNA epigenomic profiling data for validation.
