BACKGROUND AND AIM: Western reports have suggested that the prevalence of gastric cardia cancer (GCC) has been increasing, and indicated some differences between GCC and gastric noncardia cancer (GNCC). However, few studies have been conducted in Asia. The aims of this study were to estimate the prevalence of GCC and to evaluate differences of clinicopathologic characteristics between GCC and GNCC in South Korea. METHODS: This study was single-center case-control study. A total of 829 patients with gastric cancer and 270 controls were enrolled between 2003 and 2011. Baseline characteristics, Helicobacter pylori (H. pylori) infection status, and histologic characteristics were compared among three groups (GCC, GNCC, and control). RESULTS: Sixty cases (7.2%) of gastric cancer were located in cardia. Multivariate analysis showed that male odds ratio (OR, 5.72; 95% CI, 1.72-19.07; p = .005) and cigarette smoking (OR, 5.38; 95% CI, 1.39-20.90; p = .015) were risk factors of GCC in comparison with control group, but H. pylori infection rate was not significant. In the case of GNCC, cigarette smoking (OR, 3.87; 95% CI, 1.81-8.29; p < .001), past alcohol intake (OR, 2.82; 95% CI, 1.28-6.20; p = .010), intestinal metaplasia (OR, 3.22; 95% CI, 2.00-5.17; p < .001), and H. pylori infection (OR, 3.06; 95% CI, 1.90-4.93; p < .001) were risk factors of GNCC. Gastroesophageal reflux disease symptoms were higher in the GNCC (21.2%) than control group (13.5%) (p = .008). However, in the case of GCC, they were similar between the GCC (12.7%) and control group (p = .872). According to multivariate analysis, history of H. pylori eradication (OR, 0.34; 95% CI, 0.19-0.61; p < .001) was associated with a protective effect on GNCC. GCC showed higher depth of invasion (p = .038) and frequent distant metastasis (p = .012) than GNCC. CONCLUSION: In this referral center based study, the prevalence of GCC was 7.2% in South Korea. Risk factors and clinicopathologic characteristics for GCC and GNCC were different, supporting that the pathophysiology is different in the development of GCC and GNCC.
