Objective: The propensity for colorectal liver metastasis to invade the biliary tree is increasingly recognized, placing particular emphasis on the risk of postoperative recurrence. This article illustrates the spectrum of imaging findings when colorectal metastasis invades the biliary tree.
Conclusion: Knowledge of the imaging features of intrabiliary invasion by colorectal liver metastasis improves the quality of preoperative staging and is crucial in an era in which nonanatomic wedge resection and radiofrequency ablation are routinely performed.

Purpose: This study examined the roles of nuclear factor erythroid 2-related factor 2 (NRF2) and programmed death ligand 1 (PD-L1) in colon carcinogenesis, underscoring on sex and differences in tumor location.
Materials And Methods: A total of 378 participants were enrolled from Seoul National University Bundang Hospital: 88 healthy controls (HC), 139 patients with colorectal adenoma (AD), and 151 patients with colorectal cancer (CRC). Quantitative real-time polymerase chain reaction (PCR), methylation-specific PCR, and immunohistochemistry (IHC) were performed utilizing tumor samples from patients and normal mucosa in the HC group.

Differences in prognostic outcomes are prevalent in patients with colorectal cancer liver metastases. Comparative analysis of tissue samples, particularly applying single-cell transcriptome sequencing technology, can provide a deeper understanding of potential impacting factors. However, long-term monitoring for prognosis determination necessitates extended preservation of tissue samples using formalin-fixed and paraffin-embedded (FFPE) treatments, which can cause substantial RNA degradation, presenting challenges to single-cell or single-nucleus sequencing.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations.

Background & Aims: Colorectal cancer (CRC) ranks second globally in cancer-related deaths and there is ongoing debate on the best populational screening strategy. This study aimed to evaluate individuals' intention to adhere to CRC screening, screening method preference, and barriers to screening.
Methods: Cross-sectional study conducted in northern Portugal, where a populational fecal occult blood test (FOBT) program is implemented.
