ABSTRACT
BACKGROUND:
Colorectal stents are frequently used in patients with stage IV colorectal cancer with obstruction. However, there are only few studies on changes in outcomes of these patients and on the effect of stents on outcome over a long period of time with ongoing changes in therapeutic strategy, including chemotherapy.METHODS:
We retrospectively evaluated 353 patients with bowel obstruction in stage IV colorectal cancer who underwent colonic stenting between years 2005 and 2014. The study population was divided into three groups based on time periods 2005-2008, 2009-2011, and 2012-2014.RESULTS:
The frequency of colorectal stent insertion procedure increased over the time periods (13.8%, 18.3%, and 20.8%, respectively). There were no changes in success rate and total complication rate. However, the early complication rate in the 3rd period was significantly lower than in the other periods (15.4% vs. 17.1% vs. 7.2%; P = 0.039). In the multivariate analysis, carcinomatosis (hazard ratio, 1.478; 95% confidence interval, 1.016-2.149; P = 0.041) and covered or partial-covered stent (hazard ratio, 1.733; 95% confidence interval, 1.144-2.624; P = 0.009; hazard ratio, 1.988; 95% confidence interval, 1.132-3.493; P = 0.017, respectively) were associated with increased complication rate. Stent-related perforation was an independent risk factor related with increased mortality. Although survival duration increased over time (P = 0.042), the mortality rate was unchanged across the three time periods.CONCLUSIONS:
Over 10 years, the targeted agent use and survival duration increased, and early complication rate was decreased, without change in late complication rate or mortality rate during the three time periods in patients with obstructive stage IV colorectal cancer and stent insertion.Palavras-chave
