ABSTRACT
Objective@#The National Central Cancer Registry (NCCR) collected esophageal data of local cancer registries in 2013 to estimate the incidence and mortality in China.@*Methods@#Data submitted from 347 registries were evaluated and 255 registries' data are qualified by NCCR. Data of incidence and mortality were stratified with areas (urban/rural), gender and age group. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality.@*Results@#All of 255 cancer registries covered a total of 226 494 490 population (111 595 772 in urban areas and 114 898 718 in rural areas). The morphology verified cases (MV%) of esophageal cancer accounted for 75.51% and 1.64% of incident cases were identified through death certifications only (DCO%) with mortality to incidence ratio of 0.75. The estimates of new esophageal cancer cases and deaths were 277 thousand and 206 thousand in China, respectively. The crude incidence rate of esophageal cancer in Chinese cancer registration areas was 20.35/105 (28.15/105 in male, 12.15/105 in female), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population were 13.64/105 and 13.82/105 with the cumulative incidence rate (0-74 age years old) of 1.77%. The esophageal cancer incidence and ASIRC were 13.38/105 and 8.74/105 in urban areas whereas in rural areas, they were 28.44/105 and 19.56/105, respectively. In rural areas, the crude incidence rate of esophageal cancer was 2.13 times higher than that in urban areas, and after age-standardized it remained 2.24 times higher. The esophageal cancer mortality in Chinese cancer registration areas was 15.17/105 (20.86/105 in male and 9.20/105 in female), age-standardized mortality by Chinese standard population (ASMRC) and by world standard population were 9.95/105 and 9.98/105, with the cumulative mortality rate (0-74 age years old) of 1.20%. The esophageal cancer mortality and ASMRC were 10.12/105 and 6.46/105 in urban areas, whereas in rural areas, they were 21.05/105 and 14.16/105, respectively. In rural areas, the esophageal cancer mortality and ASMRC were 2.08 and 2.19 times higher than those in urban areas. Esophageal cancer was the sixth common cancer and the fourth leading causes of cancer death, accounting for about 7.52% of all cancer cases and 9.26% of all cancer deaths.@*Conclusions@#Esophageal cancer is one of the most common cancers in China. Screening and early detection are important to reduce the incidence and mortality.
ABSTRACT
Objective To analyze the clinical features and onset factors of esophageal cancer.Methods The SPSS 13.0 software was adopted to establish the computer records management system of esophageal cancer.The clinical data in 2 261 clinically cured discharged cases of esophageal cancer from January 2011 to December 2013 were statistically analyzed.Results Forty-nine cases (2.17％) were in the 30-＜40 years old group,324 cases (14.33％) were in the 40-＜50 years old group,963 cases (42.59％) were in the 50-＜60 age group,790 cases (34.94％) were in the 60-＜70 age group and 135 cases (5.97％) were in the 70 years old or more group.Among 2 240 cases,2 031 cases (90.36 ％) showed the different differentiation degrees of squamous epithelial carcinoma by histological analysis,the invaded range displayed fibrous membrane(T3) in 759 cases(33.57％) and peripheral tissue(T4) in 682 cases(30.16％);having smoking and drinking history was in 1 281 cases(56.67％) and 1 025 cases (45.33 ％) respectively;596 cases (26.36 ％) had genetic family history,75.08 ％ was father positive or mother positive.Conclusion Esophageal cancer is mainly squamous cell carcinoma,the onset age is mainly concentrated at the age 50-＜70 years old,which is correlated with smoking and drinking years,moreover has obvious genetic susceptibility.
ABSTRACT
Background and purpose: Colorectal cancer is one of the most common gastrointestinal cancers. There were about 1.36 million new cases of colorectal cancer, which was the third highest incidence of malignant tu-mors of the world in 2012. It was the fourth leading cause of cancer death and became a serious threat to human health. The aim of the study was to estimate the colorectal cancer burden in Hebei Province with the data of cancer registries areas and analyze the trend of colorectal cancer mortality rates with three of the Hebei Province death retrospective surveys. Methods: Nine cancer registries in Hebei Province submitted cancer registry data from 2010 to 2012 to the Hebei Provincial Cancer Registry Center. The pooled data were stratified by gender and age (0, 1-4, 5-9, 10-14…80+). Proportions and incidence/mortality rates for colorectal cancer were calculated. Incidence and mortality rates were age-standardized to Chinese population census in 2000 and world Segi's population standard. Colorectal cancer mortal-ity data during the periods 1973-1975, 1990-1992 and 2004-2005 were extracted from the death retrospective surveys and analyzed. Mortality and incidence rate data from Cixian County from 1988 to 2012 and Shexian County from 2000 to 2012 were obtained in each county and analyzed using Joinpoint regression model. Results: The estimated number of newly diagnosed colorectal cancer cases and deaths from 2010 to 2012 in cancer registry areas of Hebei Provinc were 2303 and 1229, respectively. The crude incidence rate of colorectal cancer was 16.48/100000 (male 18.12/100000 and female 14.77/100000). The age-standardized incidence rate by Chinese population census (ASRC) in 2000 was 13.74/100000. The colorectal cancer mortality rate was 8.79/100000 (male 10.23/100000 and female 7.31/100000). The age-standardized mortality rate by Chinese population census (ASRC) in 2000 was 7.59/100000. The mortality rates of colorectal cancer displayed a significant increasing trend in Hebei Province from 1973-1975 to 2010-2012, with an increased rate of 28.03%. In Cixian County, the annual percentage change (APC) of colorectal cancer incidence rate was 3.55, while the APC of colorectal cancer mortality rate was 1.64 for males from 1988 to 2012. In Shexian County, the APC of colorectal cancer incidence rates were 4.68 and 9.17 for males and females from 2000 to 2012, respectively;the APC of colorectal cancer mortality was 5.61 for males in Shexian County. Conclusion: The incidence and mortality rates of colorectal cancer showed an increasing trend in Hebei Province over the past 40 years. It is an important task that colorectal cancer screening is strengthened to reduce morbidity and mortality of the colorectal cancer in Hebei Province.
ABSTRACT
Objective:To study the incidence rates of cancer in the urban area of Shijiazhuang city, China in 2012 based on the data of 2,374,827 registered residents. Methods: The incidence of diagnosed cancer cases in 2012 was obtained from the hospital reimbursement database of the medical insurance center of the city by retrieving the records on first-time reimbursement applications for the hospitalization of tumor patients from January 1 to December 31 in 2012. Population census data was obtained from the Population Department of the Shijiazhuang Public Security Bureau. The site-specific and sex-specific age-adjusted incidence rates were calculated. Results:The overall incidence rate, the age-adjusted rate of the Chinese population (ASRC), and the age-adjusted rate of the world population (ASRW) for both men and women were 237.53, 129.86, and 167.71 per 100,000 individuals, respectively. The incidence rate increased with age and peaked in the 75-79 years age groups of men and women at 1,729.42 and 867.35 per 100,000 individuals, respectively. The top ten most frequently diagnosed cancers in males were lung, stomach, colorectal, liver, esophagus, kidney, prostate, leukemia, bladder, as well as lymphoma, whereas those in females were the breast, lung, colorectal, stomach, cervical, uterine body, ovary, lymphoma, esophageal, and liver cancers. The incidence rate and ASRW of all cancers combined in men were 269.05 and 187.52 per 100,000 individuals, whereas those for women were 207.57 and 150.44 per 100 000 individuals, respectively. Compared with the average incidence rates of 31 Chinese cities in 2009, the ASRW of lung, stomach, and colorectal cancers in males from Shijiazhuang was nearly equal to the national level;however, the ASRW of breast cancer in females from Shijiazhuang was higher than the national level. When the incidence rates of Shijiazhuang in 2012 were compared with those of Beijing in 2009, the ASRW of stomach and esophageal cancers in men of Shijiazhuang was twice that of the same cancers in Beijing. However, the same parameters for the pancreatic and prostate cancers in men, as well as the thyroid and uterine body cancers in women of Beijing, were twice the values for Shijiazhuang. Conclusion: The ASRWs of the major types of cancer, such as the lung, stomach, colorectal, and breast cancers, in urban Shijiazhuang in 2012 were identical to those of the 31 Chinese cities in 2009. Compared with Beijing, the incidence rates of pancreatic, prostate, and thyroid cancers were significantly higher in Shijiazhuang, whereas those of esophageal and stomach cancers were significantly lower.
ABSTRACT
<p><b>BACKGROUND</b>Previous epidemiological studies have consistently found a positive family history of esophageal cancer is associated with a significantly increased risk of the cancer. However, whether the elevated risk could be attributed to common household exposure or inherited susceptibility is uncertain. This study aimed to highlight the effect of genetic predisposition by noting the significant differences in onset age and multiple primary cancers between esophageal squamous cell carcinoma (ESCC) cases with or without a positive family history of the cancer.</p><p><b>METHODS</b>Age at onset and the percentage of multiple primary cancers were compared between ESCCs with (n = 766) or without (n = 1 776) a positive family history of the cancer in a consecutive surgery cohort at the Department of Thoracic Surgery of Hebei Tumor Hospital and the Fourth Hospital of Hebei Medical University.</p><p><b>RESULTS</b>Overall, ESCCs with a positive family history of the cancer featured both a significantly younger age of onset and significantly more multiple primary cancers than those with a negative family history (onset age 51.83 vs. 53.49 years old, P < 0.01; percent of multiple primary cancers 5.50% vs. 1.70%, χ(2) = 25.42, P < 0.01). Both the differences were evident in subgroup analyses, but did not correlate. While age at onset differed significantly by family history among the male, smoking, and drinking groups, the difference of multiple primary cancers was significant among the otherwise nonsmoking, nondrinking, and younger onset age groups.</p><p><b>CONCLUSIONS</b>Younger age of onset and multiple primary cancers associated with ESCCs with a positive, as opposed to a negative family history of the cancer, suggest a genetic predisposition. The results of subgroup analyses indicate a younger age of ESCC development results from the interaction of environmental and genetic risk factors, but multiple primary cancers may be related only to genetic predisposition.</p>
