    High incidence of cardiac esophageal and gastric cancer epidemic and its impact on endoscopic screening strength analysis of the Enlightenment

     Abstract Objective To analyze the Shexian high incidence of cardiac and other esophageal and gastric cancer epidemic

    intensity, sharpening their combat missions, explore the specific control approach. A Comparative Analysis Shexian, Lin County, Cixian the whole population registered with esophageal cancer, cardia cancer, gastric cancer incidence and mortality

    rates, and endoscopic screening of 6233 patients involving 40 to 69-year-old crowd three kinds of cancer and precancerous lesions of the review output rate. Results southern foot of Taihang Mountain high incidence of esophageal cancer

    esophageal and gastric cardia cancer incidence or mortality in the total systemic malignant tumors accounted for 70% ~ 80%. Shexian from 2000 to 2004 the incidence of cardia of both sexes were 69.9/10 and 41.5/10 10000 10000, the mortality rate for males and females were 54.3 / 10 million and 33.2/10 million. High incidence of iodine staining to guide the use of endoscopic biopsy screening for squamous cell esophageal precancerous lesions and early cancer detection rate, but the cardia, and gastric epithelial precancerous lesions and early

    cancer detection rate is relatively low. Conclusion southern Taihang Mountains there is high incidence of esophageal cancer and gastric cardia common phenomenon of high incidence, in order to rule by early diagnosis and early reduction in the

    region from the whole upper digestive tract cancer mortality, the need to strengthen endoscopy and gastric cardia epithelial precancerous lesions and early cancer detection research.

     Key words high incidence of esophageal endoscopy screening

    for precancerous lesions of gastric cardia cancer

     0 Introduction

     China's High-Risk Area for esophageal cancer prevention and control efforts have been half a century has made great achievements, the current hot spots focused on the use of

    prevention and treatment of iodine staining of endoscopic biopsy guidance technologies for high-risk populations for

    screening, early diagnosis and treatment of precancerous lesions and early esophageal cancer cancer, in order to reduce the mortality rate of esophageal cancer [1]. We are screening the scene in recent years, found that endoscopic iodine staining technique to guide biopsy of early esophageal squamous cell carcinoma and precancerous lesions has a good detection capability, but right cardia, and gastric epithelial

    cancer and early detection of precancerous lesions is still is not ideal. Also due to historical reasons, the last High Risk Area Cancer Registry often classified as esophageal cardia has long been the lack of cardiac morbidity or mortality related

    to the actual reported [2], cardia, and gastric epithelial cancer at the end of numerous and can not The detection rate on the level of screening to make reasonable judgments. In view of this, we Shexian population-wide cancer registration

    of the cardia cancer types as a separate register now statistics from 2000 to 2004 morbidity and mortality data, and with neighboring counties and Cixian data on forest comparison, the purpose is to analyze high incidence of esophageal and gastric cardia share further clarify the

    cardia, and gastric epithelial cancer prevention and control task, to find a new research direction.

     1 Data

     1.1 Shexian Information

     Shexian is located in the southwestern tip of Hebei Province, is located at the junction of three provinces of the southern foot of Taihang Mountains, south of Henan Province Linzhou (Linxian), East Cixian by Hebei Province, Shanxi Province, bordering the West with a total population of 383,284, of which male 198,958 people, 184,326 were women.

    County-wide cancer incidence and cause of death registration operation since 1996, methods for the county, township and village level by level monthly cancer doctors reported incidence of malignant tumor area and all-cause death card,

    county cancer registries on a monthly basis from the hand Agatanoatae all hospitals to collect cancer incidence and cause of death fill the whole card, the last county tumor registry verification, tick weight, meta-analysis.

     March 2001 ~ May 2005, we Shexian guided biopsy

    endoscopic iodine staining method of screening for the village as a unit 40 to 69-year-old population 1514 cases, screening rate of 70% or more.

     1.2 Linxian, Cixian information

     Linxian, Cixian esophagus, cardia, gastric cancer

    incidence and mortality is taken from the National Cancer Research Office edited the "Chinese pilot city and county cancer incidence and mortality," 1988 ~ 1992, 1993 and 1997 vols [3, 4]. Endoscopic screening data from two counties in [5,6].

     2 Results

     2.1 Shexian cardiac morbidity and mortality in

     As shown in Table 1 ~ 4, Shexian from 2000 to 2004 the incidence of cardia of both sexes were 69.9/10 and 41.5/10 10000 10000, the mortality rate for males and females were 54.3/10 and 33.2/10 10000 10000, and its body malignant tumors in the ranking, whether morbidity or mortality, according to both men and women after esophageal and gastric cancer, came in third place. This is by far the high incidence of esophageal cardiac morbidity and mortality, the first time.

     2.2 esophagus, cardia, gastric cancer incidence and mortality levels of the comparison table 1 Shexian, Lin County, Cixian male esophageal cancer, Ben Table 2 Shexian, Lin County, Cixian female esophageal cancer, Ben Table 3

    Shexian , Lin County, Cixian male esophageal cancer, Ben Table 4 Shexian, Lin County, Cixian female esophageal cancer, Ben

     As shown in Table 1 ~ 4, Shexian from 2000 to 2004 the incidence of esophageal cancer in males and females respectively, 97.2/10 and 51.8/10 10000 10000, gastric cancer incidence rates were 90.9/10 and 44.8/10 10000 10000, esophageal cancer slightly higher than the stomach, cardia and

    gastric cancer, but if the merger is far more than the incidence of esophageal cancer. Shexian male morbidity and

    mortality of cardiac cancer are the equivalent of about 70% of esophageal cancer, female cardiac morbidity or mortality is equivalent to about 80% of esophageal cancer.

     Linxian is not listed separately in the cardia cancer cases, from 1988 to 1992 and 1993 to 1997 the incidence of esophageal cancer in men, respectively, 92.7/10 and 81.2/10 10000 10000, gastric cancer incidence rates were 91.5/10 10000 and 82.4/10 million, the incidence of esophageal and gastric cancer is almost the same; but women slightly less than the incidence of gastric esophageal cancer.

     It is worth noting that: Shexian and Linxian 1993 to 1997, whether or gastric cardia cancer incidence and mortality in a single gastric cancer were higher than the high incidence

    of gastric cancer in Shandong Linqu the same period (including cardia) of morbidity and mortality (Linqu County from 1993 to 1997 the incidence of gastric cancer for males and females were 60.3/10 and 27.3/10 10000 10000, the death rate for males

    and females were 41.4/10 and 18.2/10 10000 10000), indicating that Shexian and Linxian as a high incidence of esophageal cancer there is high incidence of gastric cardia cancer and the phenomenon. Reposted elsewhere in the paper for free download http://

     2.3 Shexian, Lin County, Cixian three kinds of cancer and precancerous lesion detection rate of endoscopic screening in Table 5 Shexian, Lin County, Cixian 40 ~ 69-year-old residents

    of endoscopic screening for esophageal and cardia, stomach and

    the detection rate of precancerous lesions, such as shown in table 5: Shexian, Lin County, Cixian Endoscopic iodine staining and biopsy of the Methods 40 to 69-year-old

    population screening for esophageal squamous epithelium can be detected from 2.1% ~ 2.7% of the carcinoma in situ, 1.1% ~

    6.6% of severe dysplasia, and 8% of the mild and moderate dysplasia. But the comparison, endoscopy and gastric cardia adenocarcinoma within the epithelial mucosa and precancerous lesions of the detection capability is very low, in order to

    cardia example: Shexian and Linxian Mallory detection rate of adenocarcinoma in only 0.6% and 0.7%, and their respective counties the proportion of esophageal carcinoma in situ detection rate of about 1:4 (Cixian Mallory lower detection

    rate of carcinoma in situ, only 0.1%, may be related to mucosal carcinoma in situ to determine standards for obtaining more strict relevant); severe dysplasia detection rates in the cardiac glandular epithelium and esophageal squamous epithelium the ratio between the Shexian and Cixian also about 1:4; with mild to moderate dysplasia detection rate is far lower than the esophageal cardia . Taking into account the registration of men cardia cancer incidence or mortality is equivalent to about 70% of esophageal cancer, female cardiac

    morbidity or mortality is equivalent to about 80% of esophageal cancer, gastric cancer morbidity and mortality in patients with esophageal cancer compared with the Shexian and Lin County is almost the same, but the endoscopy and the

    gastric epithelium of the gastric cardia precancerous lesions and early cancer detection rates with such a low incidence rate and registration does not match the level of mortality, prompt us to endoscopy cardia and gastric cancer and precancerous lesions of early detection of the ability to be improved.

     3 Discussion

     3.1 strengthen the high incidence of upper digestive tract cancer, esophageal cancer focus on awareness of high

     Past, because of esophageal and cardiac carcinoma in the

    surgical treatment of the similarity of high incidence of cardiac tumors classified as esophageal cancer at the time of registration, resulting in high incidence of esophageal cancer
