Effectiveness of endoscopic gastric cancer screening in a rural area of Linzhou, China: results from a case-control study.

In China, a large burden of gastric cancer has remained, and endoscopic screening was expected to reduce gastric cancer mortality. Therefore, a population-based case-control study was conducted to evaluate the screening effect. The gastric cancer screening program was initiated in Linzhou in the year 2005, and endoscopic examination with indicative biopsy, for residents aged 40-69 years, was used to detect early cancer and precancerous lesion.

The association between human papillomavirus 16 and esophageal cancer in Chinese population: a meta-analysis.

Background: The role of human papillomavirus (HPV) in the development of esophageal cancer remains controversial. Our study aims to test the association between HPV 16 infection and esophageal cancer in China, providing useful information on this unclear association in Chinese population.

Methods: Studies on HPV infection and esophageal cancer were identified.

Prevalence of human papillomavirus 16 in esophageal cancer among the Chinese population: a systematic review and meta-analysis.

Background And Aim: No firm evidence of HPV infection in esophageal cancer has been established to date. The aim of this meta-analysis was to investigate the prevalence of HPV 16 in esophageal cancer in China, which had a high burden of the disease.

Materials And Methods: Studies on HPV infection and esophageal cancer were identified and a random-effects model was used to pool the summary prevalence and corresponding 95% confidence intervals (CIs).

[Analysis of cancer incidence and mortality in Henan province, 2009].

Objective: To analyze the cancer incidence and mortality of Henan province in 2009.

Methods: On basis of the criteria of data quality from the National Central Cancer Registry (NCCR), data from 6 registries in Henan province were evaluated, covering 6 061 564 people, accounting for 6.45% of the total population in Henan in 2009.

[Trend and prediction on the incidence of pancreatic cancer in China].

Objective: To analyze and predict the incidence trends and burden of pancreatic cancer from 2008 to 2015.

Methods: Registration data on pancreatic cancer of cancer registration in 1998 - 2007, were retrieved and utilized for analyzing the annual incidence of pancreatic cancer. Age-standardized rate by Chinese population (ASR) was calculated, using the direct method.

[Prediction of temporal trends in gastric cancer mortality in Linzhou city from 1988 to 2010].

Objective: To describe the temporal trends in the mortality rate of gastric cancer during the period of 1988 and 2010, and to predict the gastric cancer mortality between 2016 - 2020.

Methods: The data of gastric cancer mortality in Linzhou city between 1988 and 2010 was extracted from the cancer registry, including a total of 11 714 cases, covering 22 447 073 person-years. The mortality rate of gastric cancer of each 5-year period was calculated by sub-site and gender.

[Time trends in esophageal cancer mortality in Linzhou city in 1986 - 2010 and future prediction].

Objective: To analyze the trends in mortality of esophageal cancer and explore the effects of age, period and cohort on esophageal cancer mortality rate in Linzhou city in 1986 - 2010, and predict the mortality of esophageal cancer in 2016 - 2020.

Methods: All of the esophageal cancer-attributed deaths in 1986 - 2010 were drawn from the database in Center of Cancer and Vita Statistics in Henan Province. The numbers of the death cases and population were tabulated into 5-year age groups and 5-year period groups for each sex and linked each other.

Time trends of esophageal cancer mortality in Linzhou city during the period 1988-2010 and a Bayesian approach projection for 2020.

In recent decades, decreasing trends in esophageal cancer mortality have been observed across China. We here describe esophageal cancer mortality trends in Linzhou city, a high-incidence region of esophageal cancer in China, during 1988-2010 and make a esophageal cancer mortality projection in the period 2011-2020 using a Bayesian approach. Age standardized mortality rates were estimated by direct standardization to the World population structure in 1985.

[A descriptive analysis of mortality of brain tumor in China during 2004 - 2005].

Objective: To analyze the level of mortality of brain tumor and its changes at different periods in China.

Methods: Death records for tumor of brain and central nervous system, which the code of international classification of diseases-10 (ICD-10) were C70-C72, were extracted from the database of the Third National Retrospective Sampling Survey of Death Causes in China during 2004 to 2005. The corresponding population data was linked to the data of death records, that the total population was 142 660 482 person years (72 970 241 person years in male, 69 690 241 person years in female).

[Period survival analysis of esophageal cancer in Linzhou city of Henan province].

Objective: To analyze the survival level and variation of esophageal cancer in Linzhou city of Henan province from 1988 to 2004, and evaluate the effects of diagnosis and treatments on esophageal cancer in this area.

Methods: All incidence and death records for esophageal cancer during 1988 to 2004 were collected from Linzhou Tumor Registry. Cases with duplicate information or death certificate only were excluded.

[Descriptive analysis of incidence and time trends of esophageal and gastric cancers in Linzhou city].

Objective: To analyze the incidence and time trends of esophageal and gastric cancers in Linzhou city bassed on the data of Linxian Tumor Registry, and to provide valid reference data for research and effective estimation of cancer control in this area.

Methods: All incidence records for the both cancers during 1988-2003 were drawn from Linzhou Tumor Registry and grouped by sex, age, year and then linked to corresponding population data. The incidence rates of those two topographic site cancers were calculated and the age-adjusted rates were calculated by direct standardization to the world population.
