Adenocarcinoma of the Esophagogastric Junction:a New Topic for the Tumor Registry

Linzhou, Yangcheng, Shexian and Yangzhong counties are considered to be high-risk areas for esophageal carcinoma using traditional standards. However, based on the incidence of malignant tumors and death statistics from 1998-2002 in Chinese cities and counties, the incidence of esophageal carcinoma in these counties was not the most prominent. In these areas, the incidence of gastric cancer ranked first. So what are the differences between the above-mentioned areas and Changle in Fujina and Linqu in Shandong Province？ The authors have combined the defined norms for cardiac cancer, published by the WHO in 2000, with the epidemiological changes in high-risk areas of esophageal carcinoma. We propose to discuss the importance of cardiac cancer morbidity and death registration in tumor monitoring sites all over China, and to provide new views related to this topic of interest.

Analysis of cancer incidence and mortality in Heilongjiang cancer registries, 2016

Background:Cancer incidence rate has been increasing in recent years,and it has improved people’s living and financial burden.The incidence and mortality of malignant tumors in the Heilongjiang cancer registry area in 2016 were analyzed,which provided a scientific basis for the prevention and treatment of malignant tumors in Heilongjiang.Methods:The incidence and death data of tumors were collected from 10 tumor registration areas in Heilongjiang Province in 2016.According to the stratification of urban and rural areas and gender,the crude rate,standard rate,accumulative rates(0–74 years old)were calculated.The China 2000 population census data and Segi’s standard population were used for calculating age-standardized rates.Results:The incidence rate of malignant tumors in the Heilongjiang cancer registry area was 286.05/100,000 in 2016,age-standardized incidence rates by standard Chinese population and by standard world population were 168.11/100,000 and 164.69/100,000 with the cumulative incidence rate(0–74 years old)of 18.55%.The incidence of malignant tumors in urban areas was 313.60/100,000,and that in rural areas was 212.26/100,000.The frequency of malignant tumors in males was 295.94/100,000,higher than that in females(276.40/100,000).Lung cancer had the highest incidence followed by breast cancer,colorectal cancer,liver cancer and thyroid cancer.The mortality rate of malignant tumors in Heilongjiang cancer registration areas was 183.56/100,000,age-standardized mortality rates by standard Chinese population and by standard world population were 99.89/100,000 and 99.78/100,000 with the cumulative mortality rate(0–74 years old)of 10.95%.The mortality rate of malignant tumors in urban areas was 194.69/100,000,and that in rural areas was 153.73/100,000.The mortality rate of the male malignant tumor was 222.55/100,000,higher than that of a female malignant tumor(145.51/100,000).Lung cancer had the highest mortality followed by liver cancer,colorectal cancer,gastric cancer and breast cancer.Conclusion:Lung cancer,liver cancer,breast cancer and colorectal cancer were the most common cancers in Heilongjiang Province,which should be taken as the key cancer species for prevention and treatment.The incidence of thyroid cancer is higher in Heilongjiang Province,but the mortality rate is lower,which also needs attention.
