Nasopharyngeal carcinoma: nationwide trends in subtype-specific incidence and survival over 3 decades in a non-endemic area.

ABSTRACT:

Purpose

To identify trends in incidence and survival of NPC, subdivided by EBV status and histopathological subtype, over a 30-year period in the Netherlands.

Methods

Anonymized data from the Netherlands Cancer Registry and the Dutch Nationwide Pathology Databank (PALGA) for the period 1989-2018 were linked to identify and classify NPC cases.

Results

Incidence of NPC remained stable, with an annual percentage change (APC) of - 0.2. (95% CI - 0.9; 0.5). EBV testing became routine only in the last decade, the incidence of EBV-positive tumors remained stable over this period (APC 1.2, 95% CI - 1.3; 3.8). An increase in EBV-negative tumors (APC: 7.1, 95% CI 2.5; 11.9) and a decrease in untested tumors were found (APC: - 10.7, 95% CI - 15.7; - 5.7). The incidence of non-keratinizing, differentiated tumors increased (APC: 3.8, (95% CI 2.2; 5.5) while the incidence of other histological subtypes remained stable. Overall survival was better in patients diagnosed after 1998 (hazard ratio 0.8, 95% CI 0.6; 0.9). EBV status, histology, stage, and age were independently associated with relative excess risk of dying, but period of diagnosis was not.

Conclusion

Testing for EBV increased over time, and a stable incidence of EBV-positive NPC over the last 10 years. The rising incidence of non-keratinizing, differentiated NPC mirrors data from the US and suggests a shift in non-endemic regions.

Project description:BackgroundDengue, the fastest-spreading vector-borne disease (VBD), significantly burdens global health systems. This study analyzed the trends in the global burden of dengue from 1990 to 2021, utilizing data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 (GBD 2021).Methodology/principal findingsWe retrieved data from GBD 2021 regarding dengue, including the number of incidences and age-standardized incidence rate (ASIR), the number of deaths and age-standardized death rate (ASDR), disability-adjusted life-years (DALYs) and age-standardized DALYs. The estimated annual percentage change (EAPC) of ASIR, ASDR, and standardized DALYs rate was calculated to quantify trends over time. In addition, the correlations between dengue burden and sea level rise, as well as the Socio-Demographic Index (SDI), were evaluated. In this study, it was observed that from 1990 to 2021, the global incidence of dengue escalated from 26.45 million to 58.96 million cases, accompanied by an increase in related deaths from 14,315 to 29,075, and DALYs rising from 1.25 million to 2.08 million years. These data collectively indicate that the disease burden approximately doubled, with South Asia, Southeast Asia, and tropical Latin America being the most severely affected regions. The disease burden remained substantial in middle and low-middle-SDI regions, whereas high-middle and high SDI regions experienced pronounced growth rates in ASIR, ASDR, and age-standardized DALYs rate. Adolescents and the elderly showed higher incidence, yet children under 5 had the highest DALYs. Correlation analyses revealed an inverted U-shaped relationship between the SDI and both the ASDR and age-standardized DALYs rate, and changes in sea level height strongly correlated with the overall dengue burden.Conclusions/significanceThe global dengue burden has surged due to climate change, vector transmission, and population mobility. Increased focus and tailored control strategies are essential, particularly in South Asia, Southeast Asia, and Latin America.

Project description:Background Premature onset of cardiovascular disease (CVD) imposes a significant societal burden and challenges prevention efforts. Methods and Results Trends in the incidence of premature CVD (before age 55, 60, or 65 years, separate analysis for each threshold) were evaluated in 14 464 Framingham Heart Study participants over 7 decades of observation (1950-2019). The change in the incidence of premature CVD (per decade) in men and women was assessed using overdispersed Poisson regression (accounting for cohort effects), adjusting for age at entry and age at onset of premature CVD within each decade. CVD was defined as a composite of fatal or nonfatal coronary heart disease, stroke or transient ischemic attack, peripheral vascular disease, and heart failure. There were 2223 first CVD events (832 in women) before age 65 years during 282 481 person-years of observations (154 587 in women) between 1950 and 2019. The age-adjusted CVD incidence before age 65 years decreased from 14.8 per 1000 person-years (1950-1959) to 4.69 per 1000 person-years (2010-2019) in men and from 7.23 per 1000 person-years (1950-1959) to 1.73 per 1000 person-years (2010-2019) in women. In adjusted analyses, the incidence of premature CVD decreased per decade in men (18.4% [95% CI, 12.0%-24.0%], for onset before age 55 years; 19.5% [95% CI, 12.0%-27.0%], for onset before age 60 years; 21.3% [95% CI, 16.0%-27.0%], for onset before age 65 years) and women (15.1% [95% CI, 7.0%-22.0%], for onset before age 55 years; 14.0% [95% CI, 6.0%-22.0%], for onset before age 60 years; 18.2% [95% CI, 12.0%-24.0%], for onset before age 65 years). The decline in premature CVD was accompanied by a reduction in smoking and increased use of lipid-lowering treatments across the decades. Incidence of premature coronary heart disease decreased, whereas the contribution of stroke to premature CVD burden increased over time. Conclusions The incidence of premature CVD has decreased among White adults in the Framingham cohort over the past 70 years; the residual burden of premature stroke warrants further study. Additional studies of trends in premature CVD in more racially and geographically diverse populations are warranted to elucidate the generalizability of these findings.
