Epidemiological Patterns of Cancer Incidence in Southern China: Based on 6 Population-based Cancer Registries

Abstract

Background: The epidemiological patterns of cancer incidence have been investigated widely in western countries. Nevertheless, information is quite limited in Jiangxi province, southern China. Materials and Methods: All data were reported by 6 population-based cancer registries in Jiangxi Province. The results were presented as incidence rates of cases by site (ICD-10), sex, crude rate (CR), age-standardized rates (ASRs) and truncated incidence rate (TR) per 100,000 person-years, using the direct method of standardization to the world population. Results: 8,765 new cancer cases were registered in our study during the period 2009-2011. Diagnosis of cancer was based on histopathology in 61.0%, clinical or radiology findings in 4.87% and death certificate only (DCO) in 3.0% of the cases. The median age at diagnosis was 62.0 years (mean, 61; standard deviation, 15). The ASRs were 170.8 per 100,000 for men and 111.2 for women. The ASRs for all invasive cancers from the urban areas (145.7 per 100,000) was higher than that of rural areas (137.1). Incidence rates for lung cancer were higher in rural (35.8) than in urban areas (27.0). Similarly, relatively high rates were observed for stomach cancer in rural (20.1) relative to urban areas (15.5). Conclusions: Our results reveal that the most common cancers were breast and lung in women and lung and liver in men. Interestingly, this study suggested a higher incidence rates for lung and stomach cancer in rural males than in urban population, which may suggest other potential causes, such as over-consumption of smoked meats and high prevalence of Helicobacter pylori infection, respectively. Public education and the promotion of healthy lifestyles should be actively carried out.

Hepatitis B Virus Infection Is Associated with Poor Prognosis in Patients with Advanced Non Small Cell Lung Cancer

“…Meanwhile, Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer death among men and women in China, contributing to 0.5 million deaths each year (Xie et al, 2012;She et al, 2013;Deng et al, 214;Liu et al, 2014). In light of this high prevalence of lung cancer and HBV infection in certain areas, lung cancer patients who are concurrently infected with HBV are frequently seen.…”

“…Due to high prevalence of hepatitis B virus (HBV) infection and cancer in some developing countries, especially China, concurrent infection with HBV is not uncommon in cancer patients (Sun et al, 2002;Lu et al,2010;Xie et al, 2012;She et al, 2013;Deng et al, 2014;Liu et al, 2014). Recently, the association of HBV infection and cancer has been extensively investigated.…”

Trends and Analysis of Cancer Incidence for Common Male and Female Cancers in the Population of Punjab Province of Pakistan during 1984 to 2014

“…There were 8, 000, 000 new incidence cases and 5,300,000 new death cases in the less developing regions (Ferlay et al, 2012;Chen et al, 2013). The cancer incidence and mortality rates are continuously increasing in the Asian Pacific region Curado et al, 2008;NCRP 2013;Liu et al, 2014).…”

“…In addition, the incidence of lung cancer has been rising steadily (Jemal et al, 2011;Fathallah et al, 2013;Liu et al, 2014). Nonsmall cell lung cancer (NSCLC) accounts for 80% of all pulmonary carcinomas.…”
