Abstract
AIM
To retrospectively analyze the epidemiological characteristics and survival of Chinese Hui and Han patients with three types of upper gastrointestinal cancer in Ningxia.
METHODS
A total of 5616 hospitalized Hui and Han patients with upper gastrointestinal cancer (esophageal cancer, cardia cancer or gastric cancer) treated at the General Hospital of Ningxia Medical University from January 1, 2003 to December 31, 2012 were included in this study. The date of diagnosis was set as a starting point for observation and the date of death due to upper gastrointestinal cancer was set as the end of the observation, with a calculated survival time as of January 26, 2016. All patients who underwent surgery for upper gastrointestinal cancer (3634 cases) were followed by telephone, and a final successful follow-up was achieved in 1454 patients. A database was created to analyze the clinical characteristics including patients' age, sex, ethnicity, hospitalization time, outcome variables, and survival time by descriptive statistical method. The 1-, 3-, and 5-year survival rates were calculated using the life-table method. The median survival time was calculated by Kaplan-Meier method. Survival rates were compared using the Log-rank test.
RESULTS
Of the 5616 hospitalized patients included, 4695 (83.5%) were Han Chinese, and 921 (16.5%) were Hui Chinese. The ratio of Han to Hui patients was 5.10:1. There were 4325 male patients (77.0%) and 1291 female patients (23.0%). The ratio of male to female patients was 3.35:1. There were 1563 (27.8%) cases of esophageal cancer, 1478 (26.3%) cases of cardia cancer, and 2575 (45.9%) cases of gastric cancer. Esophageal cancer and cardiac cancer were mainly seen in patients aged ≥ 60 years (67.7% and 63.9%, respectively). Gastric cancer was mainly seed in patients aged 40-60 years (45.9%) and ≥ 60 years (45.1%). Of 3634 patients who underwent surgery for upper gastrointestinal cancer, 794 had esophageal cancer, in which the median survival time of Hui and Han patients was 29 mo vs 38 mo, and the 1-, 3-, and 5-year survival rates of Hui and Han patients were 72.3% vs 74.7%, 46.8% vs 50.9%, and 23.4% vs 30.9%, respectively; 734 had cardia cancer, in which the median survival time of Hui and Han patients was 62 mo vs 33 mo, and the 1-, 3-, and 5-year survival rates of Hui and Han patients were 73.9% vs 76.3%, 58.7% vs 48.0%, and 54.3% vs 39.9%, respectively; 2106 had gastric cancer, in which the median survival time of Hui and Han patients was 98 mo vs 81 mo, and the 1-, 3-, and 5-year survival rates of Hui and Han patients were 77.3% vs 77.0%, 50.7% vs 48.1%, and 24.7% vs 22.7%, respectively. There was no significant difference in the 1, 3, 5-year survival rates between Hui and Han patients with esophageal cancer, cardia cancer or gastric cancer (P > 0.05).
CONCLUSION
The distribution of sex and age in patients with the three types of upper gastrointestinal cancer in Ningxia is similar to that in other regions of China. The number of patients with gastric cancer and cardia cancer had an increasing trend during the past years. The 5-year survival rate of patients with gastric cancer in the northern regions including Ningxia is lower than that of the southern population.
