ABSTRACT
Objective@#To investigate the mortality and life loss of malignant tumors among residents in Xicheng District, Beijing from 2014 to 2021, so as to provide the evidence for formulating the control strategy for malignant tumors.@*Methods@#Data pertaining to dead cases of malignant tumors in Xicheng District from 2014 to 2021 were collected from Beijing Integrated and Analysis Platform for Health and Disease Prevention Monitoring Information Resources. The crude mortality, standardized mortality, years of potential life lost (YPLL), years of potential life lost rate (YPLLR), rate of standardized years of potential life lost (SYPLLR), average years of life lost (AYLL) and annual percent change (APC) of malignant tumors were measured to analyze the trends in mortality of malignant tumors and life loss.@*Results@#A total of 23 202 residents died from malignant tumors in Xicheng District from 2014 to 2021, and the crude and standardized mortality rates of malignant tumors were 198.09/105 and 101.46/105, respectively. The standardized mortality of malignant tumors was 117.36/105 among men and 85.97/105 among women. The standard mortality of malignant tumors appeared a tendency towards a decline among all cases (APC=-1.515%, t=-4.289, P=0.005) and women (APC=-1.629%, t=-3.046, P=0.023), and the crude mortality of malignant tumors appeared a tendency towards a rise with age (χ2trend=49.324, P<0.001). The five most deadly malignant tumors included lung cancer, colorectal cancer, liver cancer, stomach cancer and pancreatic cancer, and lung cancer, liver cancer and colorectal cancer were the three malignant tumors with the three highest life loss, with YPLL of 18 054 person-years, 9 446 person-years and 8 179 person-years, respectively. Leukemia had the highest AYLL (15.95 years per person).@*Conclusions@#The standardized mortality of malignant tumors appeared a tendency towards a decline among residents in Xicheng District from 2014 to 2021, and men and the elderly people were at high risk of malignant tumors. Lung cancer, colorectal cancer and liver cancer were leading causes of death, leukemia was the major cause of life loss.
ABSTRACT
Objective@#To investigate the trends in mortality and life lost due to cancer among residents in Ouhai District, Wenzhou City from 2013 to 2020, so as to provide the evidence for formulating the cancer control strategy. @*Methods@#The mortality data of cancer patients in Ouhai District from 2013 to 2020 were collected through Zhejiang Provincial Information Management System for Surveillance of Chronic Diseases. The crude mortality, standardized mortality, years of potential life lost ( YPLL ), years of potential life lost rate ( YPLLR ), standardized years of potential life lost ( SYPLL ), standardized years of potential life lost rate ( SYPLLR ), average years of life lost ( AYLL ) and annual percent change ( APC ) were estimated to analyze the trends in mortality and life lost due to cancer.@*Results@#Totally 5 435 deaths occurred due to cancer in Ouhai District from 2013 to 2020, and the crude and standardized mortality rates were 154.10/105 and 119.41/105, respectively. The crude mortality of cancer was higher in men than in women ( 196.26/105 and 111.09/105; χ2=415.623, P<0.001 ). The standardized mortality of cancer among whole populations, the crude mortality in men and the standardized mortality in men showed a tendency towards a reduction ( P<0.05 ), with APC of -3.25%, -2.18% and -4.78%, respectively. The crude mortality of cancer showed an upward trend with age ( χ2trend=9 260.583, P<0.001 ). Lung cancer, liver cancer, stomach cancer, colorectal cancer and esophagus cancer were the five leading causes of cancer-related mortality, which accounted for 66.68% of all cancer mortality. Liver cancer, lung cancer, stomach cancer, colorectal cancer and brain cancer were the five leading causes of life lost, with YPLL of 11 191.50, 8 231.00, 6 000.00, 3 892.00 and 2 693.50 person-years, respectively. Leukemia was the primary cause of AYLL ( 25.17 years per person ).@*Conclusions@#Both the standardized mortality and the life lost due to cancer showed a tendency towards a reduction in Ouhai District from 2013 to 2020, and men and the elderly were high-risk populations. Lung cancer, liver cancer, stomach cancer, colorectal cancer, leukemia, brain cancer, and female breast cancer should be listed among cancers in Ouhai District prioritized for control
ABSTRACT
Background and purpose:With lifestyle shifts, incidence and mortality patterns for cancers have changed. In order to provide scientiifc basis for the government to control the diseases, this study investigated the can-cer mortality among residents of Rugao city for the period 2008 through 2012.Methods:The epidemiological study of cancer mortality rates among residents of Rugao city was carried out. The results were analyzed with Excel and SPSS software.Results:Cancer was the leading cause of death. The crude mortality rate was 264.55/100 000 and the SMR (standardized mortality ratio) was 155.04/100 000. The mortality of cancer was higher in the male than in the female patients. The top 5 causes of cancer death among residents of Rugao city were esophageal cancer, liver cancer, lung cancer, gastric cancer, and pancreatic cancer for the period 2008 through 2012. Pancreatic cancer and colon, rectum and anus cancer were the iffth and sixth leading causes of cancer death in both male and female, respectively. Nervous system tumor was the eight leading cause of cancer death, whereas osteosarcoma was the tenth. Prostate cancer was the ninth leading cause of cancer death in men. The mortality of cancer was signiifcantly higher in the elderly group than in any other age group. The most common causes of cancer death in adolescents and young adults were leukemia,nervous system tumor and osteosarcoma. The top ifve of potential years of life lost (PYLL) were liver cancer, esopha-geal cancer, lung cancer, gastric cancer and leukemia. The top ifve of average years of life lost (AYLL) were leukemia, nervous system tumor, liver cancer, breast cancer and osteosarcoma.Conclusion:Cancer has been the major cause of death in residents of Rugao city. The mortality of cancer was higher in the male than in the female. Cancer mortality was also higher in the elderly group than in any other age group. Pancreatic cancer was the iffth leading cause of cancer death. Researchers should raise awareness of cancer prevention in the residents. Treatment and prevention of pancreatic cancer, nervous system tumor and osteosarcoma should be emphasized in the prevention of the most common types of cancer. Besides, researchers should focus on early diagnosis, early treatment of cancer and screening of high-risk groups to improve the quality of life of cancer patients.
ABSTRACT
Objective] To analyze the death causes of malignant tumors among residents in Ouhai District of Wenzhou City and provide basis for formulating targeted intervention . [ Methods] The causes of death from 2010 to 2012 were classified according to International Classification of Diseases ( ICD-10 ) and statistically analyzed by the death cause statistical software DeathReg 2005, Excel, and SPSS13.0. [ Results] The annual average mortality of malignant tumors among residents in Ouhai District was 150.41/100 000, the standardized mortality rate was 130.02/100 000.The mortality of malignant tumors was 197.48/100 000 in males and 101.93/100 000 in females, and there was significant gender difference .The top five death causes of malignant tumors were lung cancer , hepatic carcinoma , gastric cancer , colon-rectum-anus cancer , and esophagus carcinoma .The malignant tumor death causes in different age groups were different , and the mortality rate rose with the increase of age .The potential years of life lost ( PYLL) of malignant tumor death was 14 634.5 person-years.The average years of life lost ( AYLL) and PYLL rate were 8.01 years/person and 12.05‰, respectively. [Conclusion] The first cause of death among residents is malignant tumor in Ouhai District of Wenzhou City .According to characteristics of different tumors for different population, comprehensive intervention measures should be implemented to reduce the morbidity of malignant tumors .
