ObjectivesDisparities in the global burden of breast cancer have been identified. We aimed to investigate recent patterns and trends in the breast cancer incidence and associated mortality. We also assessed breast cancer-related health inequalities according to socioeconomic development factors.DesignAn observational study based on the Global Burden of Diseases.MethodsEstimates of breast cancer incidence and mortality during 1990–2016 were obtained from the Global Health Data Exchange database. Subsequently, data obtained in 2016 were described using the age-standardised and age-specific incidence, mortality and mortality-to-incidence (MI) ratios according to sociodemographic index (SDI) levels. Trends were assessed by measuring the annual percent change using the joinpoint regression. The Gini coefficients and concentration indices were used to identify between-country inequalities.ResultsCountries with higher SDI levels had worse disease incidence burdens in 2016, whereas inequalities in the breast cancer incidence had decreased since 1990. Opposite trends were observed in the mortality rates of high and low SDI countries. Moreover, the decreasing concentration indices, some of which became negative, among women aged 15–49 and 50–69 years suggested an increase in the mortality burdens in undeveloped regions. Conversely, inequality related to the MI ratio increased. In 2016, the MI ratios exhibited distinct gradients from high to low SDI regions across all age groups.ConclusionsThe patterns and trends in breast cancer incidence and mortality closely correlated with the SDI levels. Our findings highlighted the primary prevention of breast cancer in high SDI countries with a high disease incidence and the development of cost-effective diagnostic and treatment interventions for low SDI countries with poor MI ratios as the two pressing needs in the next decades.

ObjectiveTo evaluate the trends in disease burden and the epidemiological features of liver cancer in China while identifying potential strategies to lower the disease burden.DesignObservational study based on the Global Burden of Diseases.ParticipantsData were publicly available and de-identified and individuals were not involved.Measurement and methodsTo measure the liver cancer burden, we extracted data from the Global Health Data Exchange using the metrics of prevalence, incidence, mortality and disability-adjusted life years (DALYs). Joinpoint and negative binomial regressions were applied to identify trends and risk factors.ResultsFrom 1997 to 2016, the prevalence, incidence, mortality and DALYs of liver cancer in China were from 28.22/100 000 to 60.04/100 000, from 27.33/100 000 to 41.40/100 000, from 27.40/100 000 to 31.49/100 000 and from 10 311 308 to 11 539 102, respectively. The prevalence, incidence and mortality were increasing, with the average annual percent changes (AAPCs) of 4.0% (95% CI 3.9% to 4.2%), 2.1% (95% CI 2.0% to 2.2%) and 0.5% (95% CI 0.2% to 0.9%), respectively. Meanwhile, the rate of DALYs was stable with the AAPCs of −0.1% (95% CI −0.4% to 0.3%). The mortality-to-incidence ratio of liver cancer decreased from 1.00 in 1997 to 0.76 in 2016 (β=−0.014, p<0.0001). Males (OR: 2.98, 95% CI 2.68 to 3.30 for prevalence, OR: 2.45, 95% CI 2.21 to 2.71 for incidence) and the elderly individuals (OR: 1.57, 95% CI 1.55 to 1.59 for prevalence, OR: 1.58, 95% CI 1.56 to 1.60 for incidence) had a higher risk. Hepatitis B accounted for the highest proportion of liver cancer cases (55.11%) and deaths (54.13%).ConclusionsThe disease burden of liver cancer continued to increase in China with viral factors as one of the leading causes. Strategies such as promoting hepatitis B vaccinations, blocking the transmission of hepatitis C and reducing alcohol consumption should be prioritised.

Incidence And Mortality

Invasive breast cancer, the most common nonskin cancer in women in the United States, will be diagnosed in 266,120 In 2018, along with 63,960 new cases of non-invasive (in situ) breast cancer. Incidence and mortality reached a plateau and appear to be dropping in both the United States and parts of western Europe. This decline has been attributed to several factors, such as early detection through the use of screening mammography and appropriate use of systemic adjuvant therapy, as well as decreased use of hormone replacement therapy. However, the global burden of breast cancer remains great, and global breast cancer incidence increased from 641,000 in 1980 to 1,643,000 in 2010, an annual rate of increase of 3.1%. This chapter examines the etiology, epidemiology, prevention, screening, staging, and prognosis of breast cancer. The diagnoses and treatments of the four stages of breast cancer are also included. Figures include algorithms used for the systemic treatment of stage IV breast cancer and hormone therapy for women with stage IV breast cancer. Tables describe selected outcomes from the National Surgical Adjuvant Breast and Bowel Project (NSABP) P-1 and P-2 chemoprevention trials, tamoxifen chemoprevention trials for breast cancer, the TNM staging system and stage groupings for breast cancer, some commonly used adjuvant chemotherapy regimens, an algorithm for suggested treatment for patients with operable breast cancer from the 2011 St. Gallen consensus conference, guidelines for surveillance of asymptomatic early breast cancer survivors from the American Society of Clinical Oncology, and newer agents for metastatic breast cancer commercially available in the United States. This review contains 2 highly rendered figures, 8 tables, and 108 references.

(1) Background: Pedestrian injuries (PIs) represent a significant proportion of road traffic injuries. Our aim was to investigate the incidence and mortality of PIs in different age groups and sociodemographic index (SDI) categories between 1990 and 2017. (2) Method: Estimates of age-standardized incidence and mortality along with trends of PIs by SDI levels were obtained from the Global Burden of Disease from 1990 to 2017. We also forecasted the trends across all the SDI categories until 2040 using the Statistical Package for the Social Sciences (SPSS Statistics for Windows, version 23.0, Chicago, IL, USA) time series expert modeler. (3) Results: Globally, the incidence of PIs increased by 3.31% (−9.94 to 16.56) in 2017 compared to 1990. Men have higher incidence of PIs than women. Forecasted incidence was 132.02 (127.37 to 136.66) per 100,000 population in 2020, 101.52 (65.99 to 137.05) in 2030, and reduced further to 71.02 (10.62 to 152.65) by 2040. Globally across all SDI categories, there was a decreasing trend in mortality due to PIs with the global estimated percentage reduction of 37.12% (−45.19 to −29.04). (4) Conclusions: The results show that PIs are still a burden for all SDI categories despite some variation. Although incidence and mortality are expected to decrease globally, some SDI categories and specific vulnerable age groups may require particular attention. Further studies addressing incidence and mortality patterns in vulnerable SDI categories are needed.
