The Cancer Physics and Engineering Laboratory is interested in achieving the long-term survival and well-being of those suffering from a range of gastrointestinal cancers, with particular emphasis on pancreatic cancer. As these cancers are not detected until the time when metastasis may have already occurred, our lab is working on both early detection as well as post-metastatic treatment options. To discover new prognostic and predictive markers we employ 1.) image analysis, 2.) mathematical modeling, and 3.) liquid biopsies/tissue sampling. To develop precision medicine, biomarker-driven treatments, we are investigating the combinations of immune and radiation therapies through 1.) single-cell sequencing, 2.) cytokine profiling, 3.) lineage-tracing, and 4.) biochemical analysis.

Computed Tomography–Based Biomarker Outcomes in a Prospective Trial of Preoperative FOLFIRINOX and Chemoradiation for Borderline Resectable Pancreatic Cancer
Effective preoperative regimens and biomarkers for pancreatic ductal adenocarcinoma (PDAC) are lacking. We prospectively evaluated fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX)-based treatment and imaging-based biomarkers for borderline resectable PDAC.
Patients with high-delta tumors had lower 3-year PFS and 3-year OS rates than those with low-delta tumors (both P < 0.05). Patients with type II interface responses had lower 3-year PFS and 3-year OS rates than those with type I responses (both P < .001).

A Visually Apparent and Quantifiable CT Imaging Feature Identifies
Biophysical Subtypes of Pancreatic Ductal Adenocarcinoma
Pancreatic ductal adenocarcinoma (PDAC) is a heterogeneous disease with variable presentations and natural histories of disease. We hypothesized that different morphologic characteristics of PDAC tumors on diagnostic computed tomography (CT) scans would reflect their underlying biology.
In localized and metastatic PDAC, quantifying the change in enhancement on CT scans at the interface between tumor and parenchyma (delta) demonstrated that patients with conspicuous (high-delta) tumors had significantly less stroma, higher likelihood of multiple common pathway mutations, more mesenchymal features, higher likelihood of early distant metastasis, and shorter survival times compared with those with inconspicuous (low-delta) tumors.

Transport properties of pancreatic cancer describe
gemcitabine delivery and response
We are developing quantitative methods to characterize the imaging properties of human pancreatic cancer. Our recent pancreatic cancer research in JCI shows that imaging-derived transport properties of this disease associate with the delivery of, response to, and outcome after cytotoxic therapies.

Development of an Immune-Pathology Informed Radiomics Model for Non-Small Cell Lung Cancer
We are leveraging immune-pathology features from tissue sections and translating that information into the first immune-informed radiomics model. We have created a web application to facilitate clinical utility.
We hypothesize that this entirely noninvasive model can be used in the current era to further elucidate the prognostic utility of the local immune environment and can be enhanced to predict or monitor response to immunotherapy agents, a subject of ongoing investigation.
