The past decade has seen a significant survival improvement for patients with metastatic colorectal cancer, fueled in large part by the arrival of active novel chemotherapeutic drugs and their incorporation into combination regimens. Several randomized trials have successfully integrated oxaliplatin and irinotecan into previously existing 5-fluorouracil (5-FU)-based regimens for advanced colorectal cancer, resulting in median survivals that have risen from 9 months to almost 2 years. Even as the ideal combinations and sequences of these regimens are elucidated, targeted therapies such as recently approved bevacizumab and cetuximab have been added to treatment protocols, with favorable consequences. We review the evolution of primary chemotherapy for advanced colorectal cancer, focusing on the trials that have led to the new standard first-line treatments. We also review the data on newer targeted therapies, especially in combination with cytotoxic therapy.

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.

Background: Microsatellite instability (MSI) significantly impacts treatment response and outcomes in colon cancer; however, its underlying molecular mechanisms remain unclear. This study aimed to identify prognostic biomarkers by comparing MSI and microsatellite stability (MSS).
Methods: Data from the GSE39582 dataset downloaded from the Gene Expression Omnibus database were analyzed for differentially expressed genes (DEGs) and immune cell infiltration between MSI and MSS.

Background: Gastric cancer (GC) is a common malignancy of the digestive system, with significant geographical variation in its disease burden.
Methods: This study used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to analyze three key indicators: incidence, mortality, and disability-adjusted life years (DALYs). Initially, a detailed analysis of the GC burden was conducted from global, regional, national, gender, and age perspectives.

It is well established that host immunity plays a critical role in defending against colorectal cancer (CRC) progression. Connective tissue disease (CTD) encompasses a group of heterogeneous, immune-mediated disorders that present with diverse and often non-specific initial symptoms. Raynaud's phenomenon is a common feature, complicating early diagnosis.

Objectives: is a gram-negative anaerobic bacillus associated with colorectal cancer (CRC). We aimed to determine the abundance of . and other CRC-associated bacteria using quantitative real-time polymerase chain reaction (qPCR) analysis to detect the possible correlations between tumor and normal tissues and the relationships between patients' clinical characteristics, diet, and CRC-associated bacteria.
