The FDA has approved nanoliposomal irinotecan, 5-fluorouracil, leucovorin and oxaliplatin (NALIRIFOX) for patients with metastatic pancreatic adenocarcinoma on the basis of results from the NAPOLI 3 trial, in which this four-drug regimen improved overall survival relative to a doublet regimen. Here we discuss how, in the context of prior results from the PRODIGE 4 trial testing 5-fluorouracil, leucovorin, irinotecan and oxaliplatin (modified FOLFIRINOX), NALIRIFOX does not seem to raise the bar, but rather exposes patients and health-care systems to financial toxicities.

Effectively targeting deregulated KRAS signaling remains an unmet clinical need, as current approaches commonly lead to the development of chemoresistance in clinical settings. ADAM9-mediated lysosomal KRAS degradation is now shown to counteract PDAC chemoresistance independently of mutational status.

Topobiologically complex mini-colons—which enable the faithful in vitro recapitulation of colorectal cancer tumorigenesis and its environmental determinants—offer the possibility to reduce animal use in a wide range of experimental applications.

In a recent study published in Nature, Goto et al. explore mechanisms of immune evasion in early colorectal cancers and adenomas and identify SOX17 to be crucial for immune escape through suppression of interferon-γ signalling.

A recent study reported the development and validation of the Liver Artificial Intelligence Diagnosis System (LiAIDS), a fully automated system that integrates deep learning for the diagnosis of liver lesions on the basis of contrast-enhanced CT scans and clinical information. This tool improved diagnostic precision, surpassed the accuracy of junior radiologists (and equalled that of senior radiologists) and streamlined patient triage. These advances underscore the potential of artificial intelligence to enhance hepatology care, although challenges to widespread clinical implementation remain.

Fu et al. provide data indicating a pathogenic role for Streptococcus anginosus in gastric cancer.
