Survival in colorectal cancer patients with urinary tract invasion.
OBJECTIVE
We compared overall survival and disease-free survival in colorectal cancer patients with and without invasion of urinary organs.


METHODS
We clarified the potential predictors of the overall and disease-free survivals after surgery, the factors associated with direct tumor invasion of the urinary organs, postoperative complications, recurrence sites, and survival in patients with and without urinary organ resection in 171 patients with Stage III colorectal cancer who underwent surgery, including 23 patients with tumor invasion of the urinary organs and 148 patients without invasion.


RESULTS
Old age (65 years or older), rectal cancer, and macroscopic Type 3 and 4 disease were found to be independent poor prognostic factors for the overall and disease-free survivals in all patients. The overall and disease-free survivals in patients with direct tumor invasion of the urinary organs were not shorter than those in patients without invasion. A large extent of tumors located in the cross-sectional circumference of the bowel (> or =72 percent) and a large maximum tumor size (>50 mm) were significant tumor characteristics associated with positive direct tumor invasion of the urinary organs by sigmoid and rectal cancers. Although the local recurrence of patients with tumor invasion of the urinary organs occurred more frequently in patients without invasion, there were no differences in the overall and disease-free survivals between the patients without a urinary organ resection and those with a local resection of urinary bladder or ureter.


CONCLUSIONS
The survival of patients with a urinary invasion was not shorter than that of patients without urinary invasion.
