Gastric cancer (GC) is the second leading cause of cancer death in China. It is well known that Cixian in Hebei Province is one of the highest risk areas of GC in China and worldwide. This study aims to accurate assessment of GC burden and trend in high-risk area (Hebei Province) from 1973 to 2013. The authors analyzed GC data from 21 population-based cancer registries which represented 15.25% of the entire population of Hebei Province. The collected data were stratified by 5-year age groups, gender, and area. Mortality of GC was extracted from national death surveys from 1973 to 1975, 1990 to 1992, 2004 to 2005, and 2011 to 2013. Trend analysis (1988–2013) in a high-risk area (Cixian) used the Joinpoint Model. The age–period–cohort model was used to estimate the effects of age, period, and birth cohort in GC incidence in Cixian from 1988 to 2013. The crude incidence of GC in 2011 to 2013 was 40.37/100,000 (57.53/100,000 in males and 22.55/100,000 in females). The corresponding age-standardized rate by world age-standard population was 32.18/100,000 (48.87/100,000 in males and 17.53/100,000 in females), which was 2.66-fold (2.81-fold in male and 2.34-fold in female) higher than that in the world (12.1/100,000, 17.4/100,000 in males and 7.5/100,000 in females). Males in rural areas had the highest incidence, with an age-standardized rate of 70.51/100,000. Gastric cardia cancer was primary anatomical subsite which accounting for 59.59% in GC, followed by gastric corpus (13.92%), gastric antrum (11.43%), gastric fundus (4.99%), and overlapping lesion of gastric (4.17%). The age-standardized rate of mortality from GC displayed a significant downward trend (P = 0.019) in Hebei Province from the 1990s (31.44/100,000) to the 2010s (24.63/100,000). In Cixian, the incidence of GC rose from 1988 (38.25/100,000) to 2009 (65.11/100,000). Cixian, where population-based screening of upper gastrointestinal cancer was performed, experienced the increasing rate of GC from 2000 (37.59/100,000) to 2009 (65.11/100,000) and then had a sharp decrease from 2009 to 2013 (55.30/100,000), with annual percentage change of −6.69%. Gastric cardia cancer had an increasing trend from 1988 (6.88/100,000) to 2013 (26.56/100,000). Both age and birth cohort effects played important roles in these changes. In conclusion, males in rural areas had the highest risk of GC. GC mortality rate decreased from the 1990s in Hebei Province. Endoscopic screening project for GC is an effective method of controlling the disease.
