Analysis of the failure pattern in 110 patients with radical resection of gastric cancer

Abstract

Objective To find the reasonable treatment strategy by analyzing the failure pattern and survival rates of radical resection of gastric cancer. Methods Data were collected from 110 patients with radical resection and adjuvant treatment of gastric cancer, counted up the number of cases that failure in different ways. The survival rate after operation was calculated by Kaplan-Meier. The chi-square test was used to find the differences in survival rates between different differentiation, location and gender. Results 1, 3, 5-year survival rates of 110 cases were 83.64% (92/110), 46.36% (51/110), 35.45% (39/110), respectively. Malignant ascites was the main failure type for postoperative of gastric cancer, approximately accounting for 41.51% (22/53), abdominal lymph node metastasis accounting for 30.19% (16/53), anastomotic recurrence accounting for 13.21% (7/53), abdominal implantation and mesenteric metastasis accounting for 9.43% (5/53), organ metastasis accounting for 5.66% (3/53). The 5-year local failure rate of concurrent chemoradiotherapy group was a little lower than that in adjuvant chemotherapy alone group (15.00%∶22.22%). The 1-year survival rates of adjuvant chemotherapy alone and concurrent chemoradiotherapy group were 84.44% and 80.00% respectively, with no significant difference (χ2=0.236, P=0.627). However, the 3, 5-year survival rates of the two groups were 66.67% vs 40.00% and 53.33% vs 20.00% respectively, with statistically significant differences (χ2=4.930, P=0.026; χ2=7.294, P=0.007). Conclusion Peritoneal metastasis is the most common failure pattern for the patients with gastric cancer who received radical operation and adjuvant treatment. The relapse rate of concurrent chemoradiotherapy group is lower than that in adjuvant chemotherapy alone group, but the overall survival rate is similar.
