Background/aim: Re-staging of ductal adenocarcinoma using computed tomography (CT) scan can be problematic so new imaging techniques and evaluation parameters are required. The aim of the study was to evaluate the added value of CT texture analysis in estimation of tissue changes in ductal adenocarcinoma downsized and resected after chemotherapy.
Materials And Methods: Patients with ductal adenocarcinoma downstaged after neoadjuvant treatment, and resected, were included. A pre- and post-treatment CT was obtained. In comparison, patients with disease progression were included for texture analysis evaluation at CT pre- and post-treatment. CT texture analysis results were compared.
Results: A total of 17 patients affected by un-resectable or borderline ductal adenocarcinoma reached the resectable stage after treatment. The comparison between Kurtosis pre- and Kurtosis post-treatment showed a statistically significant difference. On the contrary, in the comparison group composed of 14 patients with disease progression there was no statistical difference regarding this parameter.
Conclusion: This evaluation may represent an added value in tumor tissue changes judgment and can be extremely useful to diagnose downstaging in those cases with no evident downsizing after chemotherapy.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. The roles of the transcription factor special AT-rich binding protein-2 (SATB2) and β-catenin in PDAC have been a subject of controversy. We aimed to assess the diagnostic and prognostic impact of SATB2 and β-catenin in PDAC.

Mucinous carcinoma of the breast, also known as colloid carcinoma, is an uncommon type of differentiated adenocarcinoma, representing only 2% of all invasive breast carcinomas. It usually occurs in women ≥ 60 years of age. Mucinous carcinoma is characterized by clusters of epithelial tumour cells suspended in pools of extracellular mucin and is further divided in 2 subgroups, pure and mixed.

KRAS is the most frequently mutated driver oncogene in human cancer, and KRAS mutation is commonly found in non-small-cell lung cancer (NSCLC), colorectal cancer (CRC), and pancreatic ductal adenocarcinoma (PDAC). Inhibitors that covalently modify the mutated codon 12 cysteine have completed proof-of-concept studies in the clinic. Here, we describe structure-based design and cocrystal-aided drug optimization of a series of compounds with the 1,8-naphthyridine-3-carbonitrile scaffold.

Background: Pancreatectomy with venous resection (PVR) is nowadays considered standard. However, there is still concern about increased postoperative morbidity and impaired long-term outcome depending on the type of venous resection and reconstruction. The aim was to investigate the predictors of morbidity and long-term survival in patients undergoing PVR in a high-volume center.

Pancreatic ductal adenocarcinoma (PDAC) remains a highly lethal malignancy with poor prognosis. Antibody-drug conjugates (ADCs) and their combinations with various anti-tumor drugs have made great progress. Camptothecin, and its derivatives (Dxd, SN-38 or exatecan) targeted TOP1 are effective payloads due to their potent anti-tumor activity.
