Abstract:
Objective:To explore the relationship between cancer nodules and clinicopathological characteristics of gastric cancer, and analyze its impact on survival prognosis of gastric cancer patients.Methods:A retrospective analysis of 2 386 patients with gastric cancer who underwent radical surgery from January 1, 2012 to January 1, 2015 in the Third Surgery Department of the Fourth Hospital of Hebei Medical University was performed. The relationship between cancer nodules and clinicopathological characteristics of gastric cancer and its impact on survival prognosis of gastric cancer patients were analyzed.Results:Among the 2 386 patients, there were 459 cases (19.24%) with cancer nodules, and 1 927 cases (80.76%) without cancer nodules. Logistic multivariate analysis showed that pT staging ( P=0.036), pN staging ( P=0.024), pTNM staging ( P=0.032), Borrmann classification ( P=0.008), vascular tumor thrombus ( P=0.001) were independent risk factors for cancer nodules. The complete follow-up date of 2 273 cases (95.26%) of 2 386 patients with gastric cancer were obtained. A total of 1 259 patients relapsed and 1 152 died during the follow-up period. The 5-years overall survival (OS) rate was 49.32%, and the 5-years disease-free survival (DFS) rate was 44.61%. Among them, the 5-years OS rate and DFS rate of those with cancer nodules were 26.76% and 24.94%, while the 5-years OS rate and DFS rate of those without cancer nodules were 54.75% and 49.34%, respectively ( P<0.001). Patients with positive cancer nodules were divided into 3 groups according to the number of cancer nodules: 1 (115 cases), 2 to 3 (202 cases), and more than 4 (124 cases). The 5-years OS rates of 3 groups were 41.74%, 30.69% and 10.48%, respectively ( P<0.001). The 5-years DFS rates were 40.00%, 28.22% and 9.68%, respectively ( P<0.001). Cox multivariate analysis showed that histological type ( P=0.004), pT staging ( P=0.007), pN staging ( P=0.004), pTNM staging ( P=0.002), vascular tumor thrombus ( P=0.034), cancer nodules ( P=0.005) and the number of cancer nodules ( P=0.001) were independent risk factors for the prognosis of gastric cancer patients, and postoperative adjuvant chemotherapy ( P=0.043) was a protective factor for the prognosis of gastric cancer patients. Conclusion:Cancer nodules are closely related to the tumor stage and prognosis of gastric cancer patients. The number of cancerous nodules is an independent risk factor for the prognosis of gastric cancer patients.
