Background: The histological assessment of colorectal precancer and cancer lesions is challenging and primarily impacts the clinical strategies of secondary colon cancer prevention. Artificial intelligence (AI) models may potentially assist in the histological diagnosis of this spectrum of phenotypical changes.
Objectives: To provide a current overview of the evidence on AI-based methods for histologically assessing colonic precancer and cancer lesions.
Epithelial-to-mesenchymal transition (EMT) is a process by which epithelial cells acquire mesenchymal properties. EMT has been closely associated with cancer cell aggressiveness. The aim of this study was to evaluate the mRNA and protein expression of EMT-associated markers in mammary tumors of humans (HBC), dogs (CMT), and cats (FMT).

Its pathogenesis has recently been related to dysregulation of the immune system, with inflammatory bowel disease representing the most commonly underlying systemic conditions. Several authors have also reported an association with solid malignancies (especially gastrointestinal and breast cancer).

Methods: A comparison was made among the number of first pathologic diagnoses of malignancy made from weeks 11 to 20 of 2018, 2019, and 2020 at seven anatomic pathology units serving secondary care hospitals in northern-central Italy.
Results: Cancer diagnoses fell in 2020 by 44.
