Abstract

A recent study by Luo et al examined the relationship between the pathological types of pancreatic cancer (PC) and their imaging characteristics. While this study presented an important step toward improving diagnostic accuracy for PC, we have several concerns regarding its generalizability, cohort selection, imaging variability, statistical methods, and potential confounding factors. We recommended that future research adopt multi-center, prospective designs to improve representation and minimize bias. Additionally, incorporating advanced imaging techniques such as radiomics and artificial intelligence and conducting more comprehensive statistical analyses would be valuable. By implementing these strategies, future studies can yield more reliable and externally validated findings that improve the clinical applicability of imaging-based differentiation of PC. Addressing these methodological issues could significantly advance the field of gastrointestinal oncology and improve patient management and outcomes.

Core Tip: A study by Luo et al examined the relationship between different pathological types of pancreatic cancer (PC) and their corresponding imaging features. This present study showed an advancement in improving the diagnostic accuracy for PC. However, to further improve the robustness and applicability of the findings, it is important to adopt a multi-center, prospective research design. Such an approach would provide better generalizability and representation among diverse patient populations. Additionally, integrating advanced imaging techniques, including radiomics and artificial intelligence-driven analyses, could significantly mitigate inconsistencies among different observers, thereby elevating the precision of diagnostics. While the findings are promising, future research would greatly benefit from using multivariable analyses and strategies to address missing data, which would help control for potential confounding factors, thus reinforcing the credibility of imaging-pathology correlations. Moreover, establishing external validation cohorts is important for verifying the predictive capabilities of these findings across various clinical settings and diverse patient demographics.
