AI Article Synopsis
- The study focused on the outcomes of colon cancer patients with bladder invasion who underwent surgery at a specific hospital from 2011 to 2022.
- Among the 41 patients, those with better surgical margins showed significantly higher overall survival rates, particularly with a median survival of 71.8 months for clean margins compared to 10.5 months for positive margins.
- The findings suggest that complete resection can lead to better outcomes and that the choice between partial and radical cystectomy should consider both effective removal of cancer and quality of life, with factors like surgical margins and emergencies affecting survival.
Article Abstract
Background/aim: The aim of our study was to investigate the outcome of colon cancer with bladder invasion after surgical intervention.
Patients And Methods: Between 2011 and 2022, a total of 41 patients diagnosed with colon cancer and bladder invasion underwent surgical procedures at Taichung Veterans General Hospital. The impact of various risk factors on overall survival (OS) was assessed using Kaplan-Meier analyses and Cox proportional hazards models.
Results: Among the enrolled patients, 21 underwent radical cystectomy, while 20 underwent partial cystectomy. Twelve had tumors located in the rectum, 19 in the sigmoid colon, and 10 in both the rectum and sigmoid colon. The median OS was 71.8 months in stage 2, 50.8 months in stage 3, and 11.2 months in stage 4 (p=0.061). Median OS was 71.8 months in patients with negative surgical margins and 10.5 months in those with positive surgical margins (p=0.003). In multivariate regression analysis, positive surgical margins [hazard ratio (HR)=3.64, 95% confidence interval (CI)=1.28-10.34, p=0.015] and emergency operations (HR=4.57, 95%CI=1.34-15.55, p=0.015) significantly impacted OS.
Conclusion: Complete resection of colon cancer with bladder invasion can yield excellent oncologic outcomes. The decision between partial and radical cystectomy should balance surgical margin clearance and the preservation of quality of life. Both surgical margin involvement and emergency operations are independent risk factors for OS.

Interferon gamma (IFNγ) is well-known for its ability to stimulate immune cells in response to pathogen infections and cancer. To develop an effective cancer therapeutic vaccine, CT26 colon carcinoma cells were genetically modified to express IFNγ either as a secreted form (sIFNγ) or as a membrane-bound form. For the membrane-bound expression, IFNγ was fused with Fas (mbIFNγ/Fas), incorporating the extracellular cysteine-rich domains, transmembrane, and cytoplasmic domains of Fas.

The autonomous and active Long-Interspersed Element-1 (LINE-1, L1) and the non-autonomous Alu retrotransposon elements, contributing to 30% of the human genome, are the most abundant repeated sequences. With more than 90% of their sequences being methylated in normal cells, these elements undeniably contribute to the global DNA methylation level and constitute a major part of circulating-cell-free DNA (cfDNA). So far, the hypomethylation status of LINE-1 and Alu in cellular and extracellular DNA has long been considered a prevailing hallmark of ageing-related diseases and cancer.
