Epidemiology of gastroenterologic cancer in Henan Province, China

Abstract

AIM:To estimate the mortality rates of gastroenterologic cancers for the period between 1974 and 1999, in Henan Province, China and its epidemiologic features. METHODS:Information on death of patients with cancer was provided by the county-city registries. Population data were provided by the local police bureau. All the deaths of cancer registered were classified according to the threedigit rubric of the ICD-9. Cancer mortality rates reported herein were age-adjusted, using the world population as standard and weighted piecewise linear regression analysis. RESULTS:Total cancer age-adjusted mortality rates were 195.91 per 100 000 for males and 124.36 per 100 000 for females between 1996 and 1998. During the period of 1974-1999, a remarkable decrease took place in esophageal carcinoma, stomach cancer remained essentially stable and liver cancer, a moderate increase. Colorectal cancer was slightly increased over the last two decades. CONCLUSION:The population-based cancer registry can give an accurate picture of cancer in Henan Province, by providing a set of analyses of selected cancer mortality data as a source of reference for researchers in cancer, public health and health care services.

Esophageal Cancer Mortality during 2004-2009 in Yanting County, China

“…This was consistent with the results from other studies (He et al, 2003;Lu et al, 2003;Su et al, 2007). The gender difference was a common phenomenon for many cancers, which may partly due to a gender variation in exposure to risk factors, such as tobacco smoking and alcohol drinking, as well as exposure to some environmental and occupational chemicals.…”

Role of nucleostemin in growth regulation of gastric cancer, liver cancer and other malignancies

“…Gastric cancer is common in China, and its early diagnosis and treatment are difficult [10,11] . To investigate the mechanism of carcinogenesis of gastric cancer would facilitate its diagnosis and treatment.…”

Epidemiological investigation of esophageal carcinoma

“…Epidemiological data defined a certain geographical distribution [2] . In high mortality areas of China, Iran and Africa, the incidence of esophageal tumors is approximately equal in men and women [3] . By comparison, in low-incidence regions such as the United States and parts of Europe, there is a significant predilection for males [4] .…”
