Core Tip
Core Tip: This article challenges the conclusion that metabolic dysfunction-associated steatotic liver disease is irrelevant to pancreatic cancer outcomes. We argue that the reported lack of association stems from the use of noninvasive surrogates that fail to capture the complexity of metabolic inflammation in cachectic patients. By ignoring the heterogeneity of metabolic dysfunction-associated steatotic liver disease and the statistical impact of competing risks, current analyses likely underestimate the pro-metastatic potential of the fibrotic liver niche. Furthermore, by contrasting these limitations with mechanistic evidence of a pre-metastatic niche, we emphasize that statistical absence of correlation does not equal biological absence of causation, advocating for fibrosis-focused future research.
