“…Bladder cancer has high morbidity and mortality worldwide, with nearly 549,393 newly diagnosed cases and approximately 199,922 patients dying each year [1]. In recent years, with the increase of tobacco consumption, and the development of industrialization, the incidence of bladder cancer has been increased year by year [2][3]. In China, the incidence and mortality of bladder cancer heads the list among urinary malignant tumors [4].…”

Background: Some classification models for determining the risk of recurrence after transurethral resection of bladder tumor (TURBT) in patients with non-muscle invasive bladder cancer (NMIBC) had some shortcomings in clinical applications. This study aimed to investigate whether the European Organization for Research and Treatment of Cancer (EORTC) risk stratification was useful to predict the recurrence of NMIBC in the Han Chinese population. In addition, we developed and validated a novel risk stratification method for recurrence prediction of NMIBC. Methods: Excluding cases who do not meet the inclusion criteria, 606 patients with NMIBC from the First Affiliated Hospital of Zhengzhou University were included in the testing and validation groups. The recurrence-free survival (RFS) curve according to the EORTC risk classifications was calculated by the Kaplan-Meier and the log-rank test methods. Receiver operating characteristic (ROC) curve analysis was used to estimate the diagnosis value for recurrence. We built a logistic regression model for recurrence in NMIBC patients combining the independent recurrence prognostic factors. One external validation group including 166 patients with NMIBC from the Zhongnan Hospital of Wuhan University was also used to assess the logistic regression model. Results: There was no significant difference in RFS rates between the groups grouped according to EORTC. We constructed a novel risk model to predict recurrence by classifying patients into two groups using ten independent prognostic factors [bladder cancer-specific nuclear matrix protein 4 (BLCA-4), bladder tumour antigen (BTA), nuclear matrix protein 22 (NMP22), carcinoembryonic antigen (CEA), body mass index, smoking, family history of bladder cancer, occupational exposure to aromatic amine chemicals, number of tumours, bladder instillation of chemotherapeutic agents] to predict tumour recurrence based on logistic regression analyses (testing group). According to the novel recurrence risk classification, there was a significant difference in 5-year RFS rates between the low-risk group and the high-risk group (Validation group and the external validation group). Conclusions: Our novel classification model can be a useful tool to predict recurrence risk in the Han Chinese population with NMIBC.

“…Inside an epidemiological context is important to understand effects of age, period and cohort (APC), to consider temporal trends of a disease incidence or mortality. 8,9 Age effect is characterized by changes of a variable along the lifetime and it could be affected by biological factors. Period effect shows the trend changes due to factors which affect every age group simultaneously and could produce diverse consequences between subjects.…”

Background Recent studies suggest that Systemic lupus erythematosus (SLE) mortality rates in Spain are decreasing. However, SLE mortality in Spain has been poorly studied. The purpose of study is to assess the temporal trends of mortality rates in the Spanish population with SLE from 1980 to 2018. Methods Death records and mid-year population data were collected from the National Statistics Institute. Age-standardized mortality rates were calculated for overall population and for each sex and age group. Significant changes in mortality trends were identified by Joinpoint regressions. Also, an Age-period-cohort (APC) and Potential Years of Life Lost (PYLL) analysis was carried out to know the burden of SLE disease. Results The overall SLE mortality rates in Spain has experimented an increased through the last 39 years. Mortality rates from the period 1980–1984 was 0.83 per 1.000.000 inhabitants, reaching the value to 1.77 cases per 1.000.000 from the period 2014–2018. A decreasing trend has been observed since 1999. Conclusions SLE mortality rate has increased in Spain between 1980 and 1999, with a sustained decrease up to our days.

“…More frequent nuclear medical examinations may lead to increasing radiation exposure, resulting in an increased incidence of TC. With the acceleration of China's industrialization process, the exposure to risk factors is becoming more and more obvious [35]. From 1992 to 2017, men's carcinogens increased signi cantly.…”

Purpose: Based on the previously published reports, the incidence of thyroid cancer (TC) has been increasing in the past 25 years, and the reason for the increase is not yet clear. The present study aims to reveal the long-term trends and age–period–cohort effects for the incidence of TC in China and the U.S. from 1992 to 2017.Patients and methods: We examined the trends of TC incidence in the two countries, for the different genders (men/women) in the Global Burden of Disease (GBD 2017). We further used an age-period-cohort model to analyze age-period-cohort effects on TC incidence, and the average annual percentage change (AAPC) of rates was estimated by Join-point regression analysis.Results: TC increased with the age and period. Aging was one of the most influential factors of TC in China. The age eﬀect increased markedly in the U.S. compared with China. The period eﬀect showed an increase in China while that tended to grow steadily during 1992-2017 in the U.S. The cohort eﬀect peaked in 1963-1967 birth cohorts for men and women in China and declined consistently in the birth cohort in the U.S.Conclusion: From 1992 to 2017, due to ionizing radiation and over-diagnosis, age-standardized TC incidence rates in both genders rose in China and the U.S. The standardized incidence rate of women is higher than that of men. It is necessary to provide women with reasonable prevention and protection measures for TC. We need to apply for health services and screening to reduce ionizing radiation.
