Well-moderately differentiated (PAC006) | Poorly differentiated (PAC010) | |
---|---|---|
Patient background | Primary tumor biopsy (EUS-FNA) from 85 years old women. | Primary tumor biopsy (EUS-FNA) from 83 years old man. |
Patient tumor pathology | Pancreatic ductal adenocarcinoma, grows as irregular glandular structures in a desmoplastic stroma & locally, cribriform patterns. Tumor cells have enlarged, atypical and hyperchromatic nuclei. | Pancreatic ductal adenocarcinoma, metastases in liver. Tumor cells have large atypical and pleiomorphic nuclei on a background of necrosis. |
Treatment history | None. | None. |
PDTX tumor pathology | Pancreatic ductal adenocarcinoma, irregular glandular structures, cells with atypical nuclei and prominent nucleolus. | Large tumor cells with atypical nuclei and often prominent nucleolus. |
Genomic profiling | RNA sequencing , Whole exome sequencing, Sequenom MassArray for KRAS, Shallow sequencing (copy number) (only PDX model, not human tumor). | RNA sequencing, Sequenom MassArray for KRAS, Shallow sequencing (copy number), Whole exome sequencing (only PDX model, not human tumor). |
Oncogene mutation status | KRAS p.G12D, TP53 wildtype. | KRAS p.G12D, KRAS double amplified, TP53 p.R175H, TP53 homozygous deficient. |
