  • 简介:AbstractBackground:The cancer burden in the United States of America (USA) has decreased gradually. However, China is experiencing a transition in its cancer profiles, with greater incidence of cancers that were previously more common in the USA. This study compared the latest cancer profiles, trends, and determinants between China and USA.Methods:This was a comparative study using open-source data. Cancer cases and deaths in 2022 were calculated using cancer estimates from GLOBOCAN 2020 and population estimates from the United Nations. Trends in cancer incidence and mortality rates in the USA used data from the Surveillance, Epidemiology, and End Results program and National Center for Health Statistics. Chinese data were obtained from cancer registry reports. Data from the Global Burden of Disease 2019 and a decomposition method were used to express cancer deaths as the product of four determinant factors.Results:In 2022, there will be approximately 4,820,000 and 2,370,000 new cancer cases, and 3,210,000 and 640,000 cancer deaths in China and the USA, respectively. The most common cancers are lung cancer in China and breast cancer in the USA, and lung cancer is the leading cause of cancer death in both. Age-standardized incidence and mortality rates for lung cancer and colorectal cancer in the USA have decreased significantly recently, but rates of liver cancer have increased slightly. Rates of stomach, liver, and esophageal cancer decreased gradually in China, but rates have increased for colorectal cancer in the whole population, prostate cancer in men, and other seven cancer types in women. Increases in adult population size and population aging were major determinants for incremental cancer deaths, and case-fatality rates contributed to reduced cancer deaths in both countries.Conclusions:The decreasing cancer burden in liver, stomach, and esophagus, and increasing burden in lung, colorectum, breast, and prostate, mean that cancer profiles in China and the USA are converging. Population aging is a growing determinant of incremental cancer burden. Progress in cancer prevention and care in the USA, and measures to actively respond to population aging, may help China to reduce the cancer burden.

  • 简介:AbstractObjective:Nasopharyngeal cancer (NPC) has distinct characteristics regarding its global prevalence, initial presentation, management and patient outcomes compared to other subtypes of head and neck cancer (HNC). The mainstay of NPC treatment is chemo-radiation (C/RT) and while dysphagia is a known early and late toxicity of C/RT treatment, the nature of dysphagia post NPC treatment has had limited investigation. The objective of this review is to summarise the existing evidence regarding dysphagia following NPC to inform the future research agenda for this population. Dysphagia incidence, characteristic deficits observed across the phases of swallowing, efficacy of current dysphagia interventions, and effect on quality of life will be explored.Data sources:Databases including MEDLINE, CINAHL, Embase, Scopus and Web of Science were included.Methods:A scoping review was conducted according to PRISMA-ScR guidelines. Two independent reviewers screened selected full text articles.Results:Of the initial 2495 articles found, 28 articles were included. Reports of penetration and aspiration varied widely (0%-91.6%), with high rates of silent aspiration identified in 2 studies (42%, 66%). Oral, pharyngeal and upper esophageal phase impairments were reported. Of these, upper esophageal stasis and multiple pharyngeal stage deficits were most prevalent. The pharyngeal constrictors were found to have a significant dose-effect relationship and shielding to the anterior neck field was effective to preserve swallowing function. Six treatment studies were identified with limited evidence supporting the use of neuromuscular electrical stimulation, dilatation and swallowing exercises. Quality of life was adversely affected.Conclusions:Dysphagia is a prevalent early and late problem post NPC treatment, with impairments across all phases of the swallow. Studies on preventing dysphagia and treatment efficacy remain limited. More systematic study of the nature of dysphagia and the efficacy of treatment in this population is warranted.

  • 简介:AbstractBackground:According to the Independent High-level Commission on Non-communicable Diseases (NCD) of the World Health Organization (WHO), global reduction in lung cancer mortality has been achieved since the year 2000, although this effect is not sufficient to reach the 30% reduction of mortality from NCDs by the year 2030, as stipulated by the United Nations Sustainable Development Goal 3.4. The objective of this study was to analyze whether the lifestyle changes implemented by the WHO at country level could have an impact on mortality from this form of cancer.Methods:WHO statistics, based on the unified mortality and causes-of-death reports of Member-State countries, were used to evaluate global lung cancer mortality trends and make comparisons and assessments of different types of community-based, country-wide interventions.Results:The lung cancer mortality decline was associated with the anti-tobacco campaign initiated by the WHO in the last 15 to 20 years. Comprehensive tobacco control remained the major and most successful lifestyle modification measure. In countries with declining lung cancer mortality, 91% of countries had decreasing tobacco prevalence in males and 82% in females. Country-wide measures to increase physical activity had a strong tendency to be better implemented in countries with declining lung cancer mortality (t = 1.79, P > 0.05). Other WHO "best-buy" lifestyle modification campaigns (diet and alcohol) had been carried out for shorter periods, and their associations with lung cancer were less strong than tobacco. There was no significant difference between countries with declining and increasing lung cancer mortality in the measures for reduction of harmful alcohol use (t= 0.92, P > 0.05) and unhealthy diet reduction measures (t= 0.84, P > 0.05).Conclusion:Following WHO "best-buys" should facilitate to move countries towards the NCD including lung cancer mortality reduction targets. Governments and communities must embrace these targets with coordinated effective action for better health.
