1National cancer incidence and mortality in China, 2012显示文摘Background: Population-based cancer registration data in 2012 from all available cancer registries were collected by the National Central Cancer Registry(NCCR). NCCR estimated the numbers of new cancer cases and cancer deaths in China with compiled cancer incidence and mortality rates.Methods: In 2015, there were 261 cancer registries submitted cancer incidence and deaths occurred in 2012. All the data were checked and evaluated based on the NCCR criteria of data quality. Qualified data from 193 registries were used for cancer statistics analysis as national estimation. The pooled data were stratified by area(urban/rural), gender, age group [0, 1–4, 5–9, 10–14, …, 85+] and cancer type. New cancer cases and deaths were estimated using age-specific rates and corresponding national population in 2012. The Chinese census data in 2000 and Segi's population were applied for age-standardized rates. All the rates were expressed per 100,000 person-year.Results: Qualified 193 cancer registries(74 urban and 119 rural registries) covered 198,060,406 populations(100,450,109 in urban and 97,610,297 in rural areas). The percentage of cases morphologically verified(MV%) and death certificate-only cases(DCO%) were 69.13% and 2.38%, respectively, and the mortality to incidence rate ratio(M/I) was 0.62. A total of 3,586,200 new cancer cases and 2,186,600 cancer deaths were estimated in China in 2012. The incidence rate was 264.85/100,000(289.30/100,000 in males, 239.15/100,000 in females), the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 191.89/100,000 and 187.83/100,000 with the cumulative incidence rate(0–74 age years old) of 21.82%. The cancer incidence, ASIRC and ASIRW in urban areas were 277.17/100,000, 195.56/100,000 and 190.88/100,000 compared to 251.20/100,000, 187.10/100,000 and 183.91/100,000 in rural areas, respectively. The cancer mortality was 161.49/100,000(198.99/100,000 in males, 122.06/100,000 in females), the age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 112.34/100,000 and 111.25/100,000, and the cumulative mortality rate(0–74 years old) was 12.61%. The cancer mortality, ASMRC and ASMRW were 159.00/100,000, 107.231/100,000 and 106.13/100,000 in urban areas, 164.24/100,000, 118.22/100,000 and 117.06/100,000 in rural areas, respectively. Cancers of lung, stomach, liver, colorectum, esophagus, female breast, thyroid cervix, brain tumor and pancreas were the most common cancers, accounting for about 77.4% of all cancer new cases. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer, pancreatic cancer, female breast cancer, brain tumor, leukemia and lymphoma were the leading causes of cancer death, accounting for about 84.5% of all cancer deaths. The cancer spectrum showed difference between urban and rural, males and females both in incidence and mortality rates.Conclusions: Cancer surveillance information in China is making great progress with the increasing number of cancer registries, population coverage and the improving data quality. Cancer registration plays a fundamental role in cancer control by providing basic information on population-based cancer incidence, mortality, survival and time trend. The disease burden of cancer is serious in China, so that, cancer prevention and control, including health education, health promotion, cancer screening and cancer care services in China, should be enhanced.Wanqing Chen Rongshou Zheng Tingting Zuo Hongmei Zeng Siwei Zhang Jie He 2016Chinese Journal of Cancer Research2016,28,1:238
2Cancer incidence and mortality in China in 2013:an analysis based on urbanization level显示文摘Objective: To explore the cancer patterns in areas with different urbanization rates(URR) in China with data from 255 population-based cancer registries in 2013, collected by the National Central Cancer Registry(NCCR).Methods: There were 347 cancer registries submitted cancer incidence and deaths occurred in 2013 to NCCR.All those data were checked and evaluated based on the NCCR criteria of data quality, and qualified data from 255 registries were used for this analysis. According to the proportion of non-agricultural population, we divided cities/counties into 3 levels: high level, with URR equal to 70% and higher; median level, with URR between 30%and 70%; and low level, with URR equal to 30% and less. Cancer incidences and mortalities were calculated,stratified by gender and age groups in different areas. The national population of Fifth Census in 2000 and Segi's population were applied for age-standardized rates.Results: Qualified 255 cancer registries covered 226,494,490 populations. The percentage of cases morphologically verified(MV%) and death certificate-only cases(DCO%) were 68.04% and 1.74%, respectively,and the mortality to incidence rate ratio(M/I) was 0.62. A total of 644,487 new cancer cases and 399,275 cancer deaths from the 255 cancer registries were submitted to NCCR in 2013. The incidence rate was 284.55/100,000(314.06/100,000 in males, 254.19/100,000 in females), and the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 190.10/100,000 and 186.24/100,000 with the cumulative incidence rate(0–74 age years old) of 21.60%. The cancer mortality was 176.28/100,000(219.03/100,000 in males, 132.30/100,000 in females), and the age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 110.91/100,000 and 109.92/100,000, and the cumulative mortality rate(0–74 age years old) was 12.43%. Low urbanization areas were high in crude cancer incidence and mortality rates, middle urbanization areas came next to it followed by high urbanization areas. After adjusted by age, there was a U-shaped association between age-standardized incidence(ASIRC and ASIRW) and the urbanized ratio with the middle urbanization areas having the lowest ASIRC and ASIRW. Unlike with the agestandardized incidence, the sort order of age-standardized mortality(ASMRC and ASMRW) among three urbanization areas was reversed completely from the crude mortality. Lung cancer was the most common cancer in all areas of 255 cancer registries, followed by stomach cancer, liver cancer, colorectal cancer and esophageal cancer with new cases of 130,700, 76,200, 63,800, 60,900 and 50,200 respectively. Lung cancer was also the leading cause of cancer death in all areas of 255 cancer registries for both males and females with the number of deaths of 72,200 and 34,100, respectively. Other cancer types with high mortality in males were liver cancer, stomach cancer,esophageal cancer and colorectal cancer. In females, stomach cancer was the second cause of cancer death, followed by liver cancer, colorectal cancer and breast cancer.Conclusions: Along with the development of socioeconomics associated with urbanization, as well as the agingpopulation, the incidence and mortality keep increasing in China. Cancer burden and patterns are different in each urbanization level. Cancer control strategies should be implemented referring to local urbanization status.Wanqing Chen Rongshou Zheng Siwei Zhang Hongmei Zeng Tingting Zuo Changfa Xia Zhixun Yang Jie He 2017Chinese Journal of Cancer Research2017,29,1:305
3The influence of stage at diagnosis and molecular subtype on breast cancer patient survival: a hospital.based multi.center study显示文摘Background: Stage at diagnosis and molecular subtype are important clinical factors associated with breast cancer patient survival. However, subgroup survival data from a large study sample are limited in China.To estimate the survival differences among patients with different stages and various subtypes of breast cancer, we conducted a hospital-based multi-center study on breast cancer in Beijing, China.Methods: All resident patients diagnosed with primary, invasive breast cancer between January 1,2006 and December 31,2010 from four selected hospitals in Beijing were included and followed up until December 31,2015. Hospitalbased data of stage at diagnosis, hormone receptor status, and selected clinical characteristics, including body mass index(BMI), menopausal status, histological grade, and histological type, were collected from the medical records of the study subjects. Overall survival(OS) and cancer-specific survival(CSS) were estimated. Cox proportional hazards models were employed to evaluate the associations of stage at diagnosis and molecular subtype with patient survival.Results: The 5-year OS and CSS rates for all patients were 89.4% and 90.3%. Survival varied by stage and molecular subtype. The 5-year OS rates for patients with stage I, Ⅱ, Ⅲ, and IV diseases were 96.5%, 91.6%, 74.8%, and 40.7%,respectively, and the corresponding estimates of 5-year CSS rates were 97.1%, 92.6%, 75.6%, and 42.7%, respectively.The 5-year OS rates for patients with luminal A, luminal B, HER2, and triple-negative subtypes of breast cancer were92.6%, 88.4%, 83.6%, and 82.9%, respectively, and the corresponding estimates of 5-year CSS rates were 93.2%, 89.1 %,85.4%, and 83.5%, respectively. Multivariate analysis showed that stage at diagnosis and molecular subtype were important prognostic factors for breast cancer.Conclusions: Survival of breast cancer patients varied significantly by stage and molecular subtype. Cancer screening is encouraged for the early detection and early diagnosis of breast cancer. More advanced therapies and health care policies are needed on HER2 and triple-negative subtypes.Tingting Zuo Hongmei Zeng Huichao Li Shuo Liu Lei Yang Changfa Xia Rongshou Zheng Fei Ma Lifang Liu Ning Wang Lixue Xuan Wanqing Chen 2017Chinese Journal of Cancer2017,36,11:18
4Epidemiology and trend analysis on malignant mesothelioma in China显示文摘Objective: Population-based cancer registration data were used to analyze the epidemiology and trend of malignant mesothelioma in China, and the result would provide basic data for its prevention and control.Methods: Malignant mesothelioma data in 2013 were retrieved from the database of National Cancer Registry.Malignant mesothelioma incidence and mortality were estimated using age-specific rate by urban/rural and gender according to the national population in 2013. Malignant mesothelioma data from 22 cancer registries were used for trend analysis during 2000–2013.Results: It is estimated that there were 2,041 new malignant mesothelioma cases and 1,659 malignant mesothelioma deaths occurred in 2013. The crude incidence rate in China were 1.50/106(males 1.67/106, females1.32/106), age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 1.03/106 and 1.02/106, respectively. The crude mortality rate in China was 1.22/106(males 1.67/106, females 1.32/106), age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 0.83/106 and 0.81/106, respectively. There was an increasing trend of incidence rate for malignant mesothelioma in registration areas of China during 2000–2013 with annual percentage change(APC) of 2.5% [95% confidence interval(95% CI): 0.6%–4.5%]. After age standardization, no significant differences were observed. No matter for crude mortality rates or age-standardized mortality rates, no significant differences were observed during 2000–2013.Conclusions: Malignant mesothelioma is the major occupational and environmental neoplasm associated with asbestos exposure. The increasing incidence trend suggests that more attention should be paid on this disease.Jun Zhao Tingting Zuo Rongshou Zheng Siwei Zhang Hongmei Zeng Changfa Xia Zhixun Yang Wanqing Chen 2017Chinese Journal of Cancer Research2017,29,4:11
5Synergy of Anodic Oxidation and Cathodic Reduction Leads to Electrochemical C—H Halogenation显示文摘We herein uncovered an electrochemical C—H halogenation protocol that synergistically combines anodic oxidation and cathodic reduction for C—X bond formation. The reaction was demonstrated under exogenous-oxidant-free conditions. Moreover, this is the first example of activating CBr4, CHBr3, and CCl3Br under electrochemical conditions.Zhilin Zhou Yong Yuan Yangmin Cao Jin Qiao Anjin Yao Jing Zhao Wanqing Zuo Wenjie Chen Aiwen Lei 2019Chinese Journal of Chemistry2019,37,6:4
