[Risk factors for oncologic outcome after surgical treatment in patients with gastric cancer: a multivariable analysis of 1031 patients].
OBJECTIVE
To investigate the risk factors for the prognosis in patients with gastric cancer undergoing surgery.


METHODS
Clinical data of 1031 cases who underwent gastric cancer resection from January 2003 to December 2007 were studied using univariable analysis and multivariable regression analysis.


RESULTS
In 1031 cases,95 (9.2%) cases were early-stage gastric cancer. The other 936 (90.8%) cases were advanced gastric cancer. The tumor was resectable in 980 (95.1%) cases, of which 874 (84.8%) were curative resection,106 (10.3%) were palliative, and 51 (4.9%) were bypass procedures or laparotomy alone. The stage-specific 5-year survival rates were 93.2% (stage IA), 65.1%(stage IB), 52.3% (stage II), 41.4% (stage IIIA), 16.6% (stage IIIB) and 10.6% (stage IV), respectively. The 1-, 3- and 5-year survival rates were 80.2%, 58.0% and 48.2%, respectively. The independent risk factors associated with the prognosis of these patients were tumor size, serum albumin, curative resection, TNM staging and multidisciplinary treatment in both univariable and multivariable analyses.


CONCLUSIONS
Early curative resection is the most important treatment for the patients with gastric cancer. Individualized surgical procedure combined with multidisciplinary treatment can improve the outcome. Tumor size, serum albumin level and TNM staging are important predictors of survival in patients with gastric cancer.
