Background And Objective: Besides current clinicopathologic staging system extensively used in clinic, more information of molecular staging is need for more accurate staging of colorectal cancer (CRC). This study was to evaluate the prognostic value of metastasis-related tumor markers in CRC.
Methods: The expression of CD44v6, matrix matalloproteinase-2 (MMP-2), cyclooxygenase-2 (COX-2), epidermal growth factor (EGF), epidermal growth factor receptor (EGFR) and vascular epidermal growth factor (VEGF) in a tissue microarray containing 95 specimens of CRC were detected by immunohistochemistry (IHC). The correlations of these tumor markers to the prognosis of CRC patients were analyzed.
Results: In patients with Dukes' A/B disease, the 5-year recurrence rates were significantly higher in CD44v6-, EGF-and EGFR-positive groups than in negative groups (30.9% vs. 8.3%,P=0.045; 38.1% vs. 8.8%, P=0.022; 27.5% vs. 11.8%, P=0.047, respectively). In patients with Dukes' C disease, the 5-year recurrence rates were significantly higher in MMP-2-, COX-2-and VEGF-positive group than in negative groups (73.3% vs. 37.5%, P=0.045; 69.2% vs. 25.0%, P=0.017; 62.5% vs. 25.0%, P=0.03, respectively). In patients with Dukes' A/B disease, there were a significantly higher 5-year recurrence rate and a lower 5-year survival rate in those with more than three positive markers than in those with 1-3 positive markers (P=0.019, P=0.03). However, there was no significant difference in patients with Dukes' C disease in such condition.
Conclusions: Over-expression of CD44v6, EGF and EGFR are related to poor prognosis of Dukes' A/B CRC, while over-expression of MMP-2, COX-2 and VEGF are related to poor prognosis of Dukes' C CRC. For patients with Dukes' A/B CRC, the more positive markers, the higher 5-year recurrence rate and the poorer 5-year survival.

Background/objectives: Colorectal cancer (CRC) remains a significant health burden, and its delayed diagnosis at advanced stages leads to poor survival outcome. Detection of known and novel prognostic markers is essential. In this study, the status of likely prognostic markers-the apoptotic inducing factor (AIFM3), vestigial-like family member 4 (VGLL4), and WNT4-was evaluated.

Purpose: The landiolol and organ failure in patients with septic shock (STRESS-L study) included a pre-planned sub-study to assess the effect of landiolol treatment on inflammatory and metabolomic markers.
Methods: Samples collected from 91 patients randomised to STRESS-L were profiled for immune and metabolomic markers. A panel of pro- and anti-inflammatory cytokines were measured through commercially acquired multiplex Luminex assays and statistically analysed by individual and cluster-level analysis (patient).

Background: Aspirin is a simple, globally available medication that has been shown to reduce the incidence of colorectal cancer. We aimed to evaluate the safety and efficacy of aspirin in the secondary prevention of colorectal cancer.
Methods: This phase 3, randomised, double-blind, placebo-controlled trial was conducted at 66 centres across 11 countries and territories (ten in Asia-Pacific; one in the Middle East).

Article Synopsis
- This study highlights the importance of effective communication in the emergency department for trauma survivors, aiming to create a graphic narrative educational tool to better convey nursing concepts related to trauma-informed care.
- The tool was developed using content validation by expert nurses to ensure that the graphic narratives accurately reflect trauma-informed care values, illustrating how nurses can apply these principles in clinical scenarios.
- The final graphic narratives serve as a study guide for emergency trauma nurses, showcasing nurse-patient interactions that embody the core values of trauma-informed care and emphasizing the healing impact of these practices.
