Objective:Survival analysis of cancers' incidence data in Tianjin from 2010 to 2016 was conducted to provide the basis for formulating and evaluating regional health policies on cancer prevention and treatment.Methods:Registration data in Tianjin were used between January 1, 2010 to December 31, 2016 and patients were followed-up till 31 December, 2021. Life-table method was used to calculate the observed survival rate and Edered Ⅱ was used to calculate the relative survival rate. The data were stratified by year, gender, age group and cancer sites. Difference in survival curves between group was analyzed by Kaplan-Meier method and Log rank test. Joinpoint regression model was used to analyze the trend change.Results:The 5-year relative survival rates of cancer were 41.92% to 53.65% from 2010 to 2016 for residents in Tianjin, with an increasing trend ( t=4.81 ,P=0.005), and the average was 48.56%. The survival rate of females was higher than that of males (57.71%vs. 39.20%), and the survival rate of urban residents was higher than that of rural residents (49.38% vs. 47.24%). The 5-year relative survival rates were 63.14%, 78.39%, 58.25% and 32.67% in 0-14, 15-44, 45-64 and 65 and above age groups, respectively. The median relative survival times of all cancer were 2.34 to 6.00 years from 2010 to 2016 in Tianjin, with an increasing trend ( t=3.86, P=0.012). The average of median relative survival times was 4.11 years. The median survival time of females was longer than that of males (11.99 years vs. 2.03 years), and the time of urban residents were longer than that of rural residents (4.60 years vs. 3.43 years). The median relative survival time were 12.07, 11.92 and 1.34 years in 15-44, 45-64 and 65 and above age groups, respectively. Conclusions:The cumulative survival rate of cancer increased significantly from 2010 to 2016 in Tianjin, indicating that the prevention and treatment effect of cancer is obvious. The focus should be on male, rural areas, higher age group, and targeted prevention and treatment measures should be taken to lung, esophagus, liver, gallbladder and pancreatic cancer.

Objective:To explore the trends and distribution of liver cancer between sexes, ages, and urban-rural areas in Tianjin, China from 1999 to 2021, and provide data for targeted prevention and control strategies of liver cancer in Tianjin.Methods:Liver cancer mortality data of Tianjin during 1999-2021 were from the Tianjin population based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC), and the population data of permanent Tianjin residents were from Tianjin Municipal Public Security Bureau. Liver cancer mortality, years of life lost (YLL), years lived with disability (YLD), and disability adjusted life years (DALY) were calculated using the cause of death surveillance data collected by Tianjin Centers for Disease Control and Prevention. The distributions of these data among residents of different sexes, ages, and regions were analyzed. Segi's world standard population was used for standardization. Joinpoint regression was used for trend analysis on the mortality rate of liver cancer and the disease burden.Results:The liver cancer mortality rate in Tianjin decreased by 46.75% from 1999 to 2021, with distinct phased characteristics. From 1999 to 2010, the age-sex-standardized mortality rate (SMR) decreased from 12.62/100 000 to 11.64/100 000 with an annual percent change (APC) of -1.32% ( P=0.003). From 2010 to 2021, the SMR decreased from 11.64/100 000 to 6.72/100 000 (APC=-3.89%, P<0.001). The age-sex-standardized DALY rates(SDR) decreased by 50.63% from 1999 to 2021, also with distinct phased characteristics. From 1999 to 2010, the SDR decreased from 388.67/100 000 to 349.38/100 000 (APC=-1.35%, P=0.002). From 2010 to 2021, the SDR decreased from 349.38/100 000 to 191.88/100 000 (APC=-4.43%, P<0.001). The liver cancer mortality rate declined most rapidly in the age group under 45 years; the APC for those under 35 years was -5.07% ( P<0.001), and for those aged 35-44 years, the APC was 0.63% ( P=0.707) and -8.21% ( P<0.001) before and after 2007, respectively. Both SMR and SDR were significantly higher in males than in females ( P<0.01). Both SMR and SDR were significantly higher in urban areas than in rural areas from 1999 to 2007 ( P<0.05), but they became similar after 2008. Liver cancer DALY are predominantly YLL, accounting for 99%. The median age of liver cancer deaths in Tianjin during 1999-2021 was 64-68 years old, with males lower than females ( P<0.05), and rural areas lower than urban areas ( P<0.05), generally showing an increasing trend (1999-2014: APC=0.11%, P=0.047; 2014-2021: APC=0.51%, P=0.005). Conclusions:Liver cancer mortality rate and disease burden decreased from 1999 to 2021 in Tianjin, with an especially accelerated decline after 2010. Further efforts to reduce liver cancer mortality in Tianjin are needed, and special attention should be focused on the elderly, male, and rural residents.

Objective:To assess the trend and the factors responsible for the increase of life expectancy of residents in Tianjin over the past two decades.Methods:Abridged Life Table and Arriaga's decomposition method was applied to quantify the influence of the age structure and the leading causes of death on the increase of life expectancy of residents in Tianjin from 1999 to 2018.Results:In the past 20 years, the life expectancy of residents in Tianjin increased by 4.97 years, the life expectancy of men and women increased by 4.11 years and 5.86 years, respectively. The decrease of mortality rate in 0-year-old group contributed 19.17% to the increase of the life expectancy, while the decrease of mortality rate in residents aged ≥55 years contributed more to the increase of life expectancy, with the cumulative contribution rate of 67.38%. The major contribution to the increase of life expectancy was the mortality reduction of cerebrovascular disease, respiratory disease, cardiovascular disease, perinatal diseases, congenital malformations and injury, with the contribution percentage of 27.27%, 21.37%, 15.76%, 12.22%, 6.44% and 4.86%, respectively. The increase of mortality of malignant tumor, injury and poisoning, diabetes and nervous system diseases and others had a negative effect on the increase of life expectancy of people aged ≥75 years. From 1999 to 2018, the life expectancy increased from 76.72 years to 81.46 years ( t=9.11, P<0.001), the annual percent change (APC) was 0.58%. From 2011 to 2018, it was stable, ranging from 81.46 years to 81.69 years ( t=0.89, P=0.387, APC=0.13%). Conclusion:From 1999 to 2018, the increase of life expectancy was attributed to the decrease of mortalities in infants and the elderly and the decrease of mortalities of cerebro-cardiovascular disease, respiratory disease, perinatal disease, congenital malformations and injury. However, these positive contributions were partly offset by the negative contribution of malignant tumor, injury, diabetes and nervous system disease in those aged ≥75 years. Comprehensive prevention and control of key diseases should be strengthened in key population in order to further improve the life expectancy of the population.

Objective:To analyze the trends of mortality and years of life lost (YLL) of breast cancer in women in Tianjin and provide references for the development of intervention strategies.Methods:The crude mortality rate, standard mortality rate, cumulative rate (0-74 years old) and truncated rate (35-64 years old) of breast cancer in women in Tianjin from 1999 to 2017 were calculated. The annual percentage change of the mortality rate and YLL rate were analyzed by Joinpoint regression.Results:From 1999 to 2017, a total of 8 356 deaths of breast cancer were reported in Tianjin, resulting in a YLL of 262 835.53 person-years. The average crude mortality rate was 9.15/100 000. The average age standardized rate(ASR) (World) was 6.14/100 000. The ratio of ASR (World) between urban and rural areas was 1.73∶1. The peak mortality ratio of age groups between urban area and rural area was 3.13∶1. From 1999 to 2017, both the crude mortality rate and ASR of breast cancer in Tianjin had rising trends. In 2017, the crude mortality rate and the ASR of breast cancer increased by 113.7% and 44.4% respectively compared with 1999. The increase of urban mortality mainly came from elderly group aged ≥75 years, and the mortality of young age groups in rural area showed an fast increases, which was most obvious in age group 45-59 years (average annual percentage change=3.6%, P<0.01). Conclusions:The mortality rate of breast cancer and disease burden in women in Tianjin are still in rapid increase. We should continue to implement the prevention and control strategies such as lifestyle intervention and screening of key groups. More attention need to be paid to the increase of breast cancer incidence in rural area.

BACKGROUND: Severe cutaneous adverse reactions (SCAR) to drugs are a crucial public health issue and the use of systemic corticosteroids in SCAR has been controversial. OBJECTIVE: To analyze clinical features, causative drugs, treatment, outcomes, and prognostic factors of SCAR in the case-series of 173 patients, and add more information to the debate of using systemic corticosteroids in SCAR management. METHODS: A retrospective study of 173 SCAR patients diagnosed with drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) or acute generalized exanthematous pustulosis (AGEP) at a tertiary care institution in China between January 2014 and December 2017 was conducted. RESULTS: Of 173 patients, allopurinol, carbamazepine, and antibiotics are the most frequently implicated drugs for DRESS (40.4%), SJS/TEN (26.0%), and AGEP (40.0%) respectively. Moreover, there is a strongly negative correlation between early corticosteroids use and the progression (p=0.000) and severity (p=0.01) of skin lesions. However, there is no association between early corticosteroids use and the mortality of SCAR (odds ratio: 1.01, 95% confidence interval: 0.95~1.08). In addition, lymphadenopathy, eosinophilia, and interval from onset to corticosteroids treatment were correlated with SCAR prognosis. CONCLUSION: Prompt short-course systemic corticosteroids use is associated with early-stage skin lesions remission without influencing the disease mortality. Lymphadenopathy and eosinophilia were the independent poor prognostic factors of SCAR.

Objective To investigate the mortality of colorectal cancer and its trend from 1999 to 2015 in Tianjin, China, and to explore the mortality features in different populations in order to provide data for prevention and control strategies of colorectal cancer. Methods Colorectal cancer mortality data between 1999 and 2015 were collected from Tianjin population?based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Population data of permanent residents were collected from Tianjin Municipal Public Security Bureau. The number of new cases and deaths, incidence [including crude incidence, age?adjusted standardized incidence and 95% confidence interval (95% CI)], and mortality (including crude mortality, age?adjusted standardized mortality and 95% CI) of colorectal cancer were calculated. Standardized incidence and mortality of colorectal cancer were calculated using the Segi′s world standard population, adjusted with age and gender. JoinPoint regression and Cochran?Armitage trend test were used to determine the statistical significance of differences in mortality trend. Results A total of 31 376 new onset cases and 14 893 death cases of colorectal cancer were observed in Tianjin from 1999 to 2015. Colorectal cancer incidence increased from 1999 to 2015 with a standardized rate from 9.66/100 000 to 15.36/100 000 [annual percent change(APC)=3.48%, Z=23.21, P<0.001]. Colorectal cancer mortality increased from 1999 to 2015 with a standardized rate from 5.18/100 000 to 6.11/100 000 (APC=1.24%, Z=5.69, P<0.001). Both showed an increasing trend. The death proportion of colon cancer increased (39.67% in 1999 and 50.33% in 2015), while the death proportion of rectal caner decreased (60.33% in 1999 and 48.57% in 2015). The median age of colorectal cancer onset fluctuated steadily around 66 years old (APC=0.16, T=1.75, P=0.100); the median age of death increased from 69 to 73 years old (APC=0.43, T=8.81, P<0.001). From 1999 to 2015, the mortality of colorectal cancer showed a downward trend (all P<0.05) in the age groups of<35 and 35?44 years, while an upward trend (all P<0.05) in the age groups of 45?54 years, 55?64 years and≥65 years. Colorectal cancer mortality in males increased with a standardized rate of 5.53/100 000 in 1999 to 7.33/100 000 in 2015 (APC=2.29%, Z=7.86, P<0.001), while colorectal cancer mortality in females flatted with a standardized rate of 4.83/100 000 in 1999 to 4.89/100 000 in 2015 (APC=0.10%, Z=?0.30, P=0.752). Colorectal cancer mortality increased with a standardized rate of 6.75/100 000 in 1999 to 7.33/100 000 in 2015 (APC=0.54%, Z=1.98, P=0.048) in urban areas and of 3.18/100 000 in 1999 to 4.38/100 000 in 2015 (APC=2.47, Z=6.46, P<0.001) in rural areas, whose differences were significant. Standardized mortality rate in rural area was lower but the rising velocity was faster as compared to urban area. Conclusions Crude mortality and standardized mortality of colorectal cancer increase from 1999 to 2015 in Tianjin population. The people of elder, male and urban area have higher mortality. The mortality in people of male and rural area presents a faster rising state. Further efforts to reduce colorectal cancer mortality in Tianjin are needed to prevention and control of colorectal cancer.
