Summary
The imaging characteristics of this model (PDMR-521955-158-R4), which is available from the National Cancer Institute Patient-Derived Models Repository (https://pdmr.cancer.gov/), is highly favorable for preclinical research studies of metastatic disease when used in conjunction with non-contrast T2 weighted MRI.
Results: Adenocarcinoma pancreas (PDMR-521955-158-R4)
Table 1: Penetrance and location of pathological confirmed metastatic lesion(s).
# animals in Group | # animals that displayed metastasis in MRI and confirmed by Pathology | Pathology confirmation of MRI (primary imaging site) | Other confirmed Location (s) | Mouse ID: MRI with pathology confirmation of metastasis |
10 (non-resected) | 4 (5 mice were EU due to xenograft size prior to observation of metastases) | Lung | Lung | 2163, 2169, 2171, 2179 |
10 (resected) | 7 | Lung | Lung (70%) | 2160, 2161, 2164, 2170, 2172, 2176, 2178 |
Percent penetrance with respect to the average time-to-metastasis for non-resected (time from implant: 10.7 ± 1.8 weeks) and resected (time from tumor resection: 5.3 ± 1.1 weeks) cohorts.
PET/CT Characterization of the primary tumor: Baseline PET (SOP attached) were performed when tumor reached an approximate 200 mm3. Average SUVmax values (n=6) were calculated; [18F]FDG: 2.3 ± 0.8 and [18F]FLT: 2.4 ± 0.4.
Conclusion:
Good metastatic model with 40% penetrance un-resected and 70% with planned early resection. Metastases are well observed on T2 MRI imaging allowing non-invasive evaluation in treatment trials.

Additional Resources for this Dataset
The National Cancer Institute (NCI) has developed a national repository of Patient-Derived Models (PDMs) comprised of patient-derived xenografts (PDXs), in vitro patient-derived tumor cell cultures (PDCs) and cancer associated fibroblasts (CAFs) as well as patient-derived organoids (PDOrg). These models serve as a resource for public-private partnerships and for academic drug discovery efforts. These PDMs are clinically-annotated with molecular information and made available in the Patient-Derived Model Repository. Data related to the specific subjects in this Collection can be found at:
The NCI Cancer Research Data Commons (CRDC) provides access to additional data and a cloud-based data science infrastructure that connects data sets with analytics tools to allow users to share, integrate, analyze, and visualize cancer research data.
