The aim of our study was to perform a simplified radiomic analysis of pancreatic ductal adenocarcinoma based on qualitative and quantitative tumor features and to compare the results with different muted genes, in particular with KRAS and TP53 expression, in order to predict the outcome and, in future, to direct the therapeutic path.
Note:
Pancreatic cancer has a very poor prognosis and its most frequent isotype is represented by pancreatic ductal adenocarcinoma (PDAC). Despite advances in early diagnosis and multimodal treatments, the prognosis for patients with PDAC remains poor, with a 5-year survival rate that lies around 8%.
According to genomics, there are certain genes often mutated in PDAC’s carcinogenesis: KRAS, CDKN2a/INK4a, TP53, and DPC4/SMAD4. In particular we focused on the presence or absence of KRAS mutation as it is the most frequent mutated oncogene (95%) that determine an increased growth and survival of tumoral cells. Secondly we analyzed TP53 expression as it is demonstrated that it is inactivated in up to 75% of the PDAC.

At our knowledge, this is the first study that looks for radiogenomic data for PDAC through RM imaging.
