Disparities in 36 cancers across 185 countries: secondary analysis of global cancer statistics.

Cancer is a major public health problem and represents substantial disparities worldwide. This study reported estimates for 36 cancers across 185 countries by incidence, mortality, 5-year prevalence, mortality-to-prevalence ratio (MPR), and mortality-to-incidence ratio (MIR) to examine its association with human development index (HDI) and gross national income (GNI). Data were collected from the GLOBOCAN 2020. MPR and MIR were calculated by sex, age group, country, and cancer type and then summarized into totals. Segi's population and global cancer spectrum were used to calculate age- and type-standardized ratios. Correlation analyses were conducted to assess associations. Results showed that breast cancer was the most diagnosed cancer globally. Low- and middle-income countries had high MPR and MIR. Cancers of esophagus, pancreas, and liver had the highest ratios. Males and the older population had the highest ratios. HDI and GNI were positively correlated with incidence and mortality but negatively correlated with MPR/MIR. Substantial disparities in cancer burden were observed among 36 cancer types across 185 countries. Socioeconomic development may contribute to narrowing these disparities, and tailored strategies are crucial for regional- and country-specific cancer control.

Global, regional, and national burden of early-onset gastric cancer.

OBJECTIVE: The burden of gastric cancer (GC) across different age groups needs updating. We determined the GC global, regional, and national burden profiles and changes in incidence for 3 sequential 5-year intervals from 2003 to 2017. METHODS: The latest incidence and mortality estimates of GC from 185 countries and regions were extracted from the GLOBOCAN 2022 database. The 5-year interval age-standardised incidence rates (ASIRs) were evaluated using cancer registry data from volumes X-XII of the Cancer Incidence in Five Continents (CI5). Correlation analysis was used to evaluate the relationship between ASIR or the age-standardised mortality rate (ASMR) and the Human Development Index (HDI). RESULTS: There was an estimated global 968,000 new GC cases and 660,000 deaths in 2022, with male predominance. GC ASIRs and ASMRs were 9.2 and 6.1 per 100,000 persons, respectively. East Asia had the highest burden, with 53.8% of cases and 48.2% of deaths among all geographic regions. There was a significant correlation between ASIR and HDI. Over three 5-year intervals from 2003 to 2017, the incidence of GC notably decreased in most countries but peaked at 2008-2012 in New Zealand, Turkey, and South Africa. Several countries in Europe, Oceania, and America suggest an increasingly concerning trend among younger individuals, especially females. CONCLUSIONS: GC is a significant health issue, especially among males and in geographic regions with an HDI, such as eastern Asia. While the incidence of GC is decreasing in many countries due to prevention efforts and improved treatments, a rising trend persists among younger individuals. Comprehensive prevention strategies tailored to different age patterns are clearly needed.

Recent developments in immunotherapy for gastrointestinal tract cancers.

The past few decades have witnessed the rise of immunotherapy for Gastrointestinal (GI) tract cancers. The role of immune checkpoint inhibitors (ICIs), particularly programmed death protein 1 (PD-1) and PD ligand-1 antibodies, has become increasingly pivotal in the treatment of advanced and perioperative GI tract cancers. Currently, anti-PD-1 plus chemotherapy is considered as first-line regimen for unselected advanced gastric/gastroesophageal junction adenocarcinoma (G/GEJC), mismatch repair deficient (dMMR)/microsatellite instability-high (MSI-H) colorectal cancer (CRC), and advanced esophageal cancer (EC). In addition, the encouraging performance of claudin18.2-redirected chimeric antigen receptor T-cell (CAR-T) therapy in later-line GI tract cancers brings new hope for cell therapy in solid tumour treatment. Nevertheless, immunotherapy for GI tumour remains yet precise, and researchers are dedicated to further maximising and optimising the efficacy. This review summarises the important research, latest progress, and future directions of immunotherapy for GI tract cancers including EC, G/GEJC, and CRC.

Rosmarinic Acid Alleviates Radiation-Induced Pulmonary Fibrosis by Downregulating the tRNA N7-Methylguanosine Modification-Regulated Fibroblast-to-Myofibroblast Transition Through the Exosome Pathway.

Background: Radiation-induced pulmonary fibrosis (RIPF) is a common complication after radiotherapy in thoracic cancer patients, and effective treatment methods are lacking. The purpose of this study was to investigate the protective effect of rosmarinic acid (RA) on RIPF in mice as well as the mechanism involved. Methods: m7G-tRNA-seq and tRNA-seq analyses were conducted to identify m7G-modified tRNAs. Western blotting, immunohistochemistry, northwestern blotting, northern blotting, immunofluorescence, wound-healing assays and EdU experiments were performed to explore the molecular mechanism by which RA regulates fibroblast-to-myofibroblast transformation (FMT) by affecting the exosomes of lung epithelial cells. Ribo-seq and mRNA-seq analyses were used to explore the underlying target mRNAs. Seahorse assays and immunoprecipitation were carried out to elucidate the effects of RA on glycolysis and FMT processes via the regulation of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) acetylation. Results: We found that RA had an antifibrotic effect on the lung tissues of RIPF model mice and inhibited the progression of FMT through exosomes derived from lung epithelial cells. Mechanistically, RA reduced the transcription and translation efficiency of sphingosine kinase 1 in lung fibroblasts by decreasing N7-methylguanosine modification of tRNA, downregulating the expression of tRNAs in irradiated lung epithelial cell-derived exosomes, and inhibiting the interaction between sphingosine kinase 1 and the N-acetyltransferase 10 protein in fibroblasts. Furthermore, the acetylation and cytoplasmic translocation of PFKFB3 were reduced by exosomes derived from irradiated lung epithelial cells, which following RA intervention. This suppression of the FMT process, which is triggered by glycolysis, and ultimately decelerating the progression of RIPF. Conclusion: These findings suggest that RA is a potential therapeutic agent for RIPF.

LncRNA HOTAIRM1 promotes radioresistance in nasopharyngeal carcinoma by modulating FTO acetylation-dependent alternative splicing of CD44.

BACKGROUND: Radiotherapy is the primary treatment for patients with nasopharyngeal carcinoma (NPC); however, almost 20% of patients experience treatment failure due to radioresistance. Therefore, understanding the mechanisms of radioresistance is imperative. HOTAIRM1 is deregulated in various human cancers, yet its role in NPC radioresistance are largely unclear. METHODS: This study investigated the association between HOTAIRM1 and radioresistance using CCK8, flow cytometry, and comet assays. Additionally, xenograft mice and patient-derived xenografts (PDX) models were employed to elucidate the biological functions of HOTAIRM1, and transcriptomic RNA sequencing was utilized to identify its target genes. RESULTS: Our study revealed an upregulation of HOTAIRM1 levels in radioresistant NPC cell lines and tissues. Furthermore, a positive correlation was noted between high HOTAIRM1 expression and increased NPC cell proliferation, reduced apoptosis, G2/M cell cycle arrest, and diminished cellular DNA damage following radiotherapy. HOTAIRM1 modulates the acetylation and stability of the FTO protein, and inhibiting FTO elevates the m6A methylation level of CD44 precursor transcripts in NPC cells. Additionally, silencing the m6A reading protein YTHDC1 was found to increase the expression of CD44V. HOTAIRM1 enhances NPC cell resistance to ferroptosis and irradiation through the HOTAIRM1-FTO-YTHDC1-CD44 axis. Mechanistically, HOTAIRM1 interacts with the FTO protein and induces m6A demethylation of the CD44 transcript. The absence of m6A modification in the CD44 transcript prevents its recognition by YTHDC1, resulting in the transition from CD44S to CD44V. An abundance of CD44V suppresses ferroptosis induced by irradiation and contributes to NPC radioresistance. CONCLUSIONS: In conclusion, the results in this study support the idea that HOTAIRM1 stimulates CD44 alternative splicing via FTO-mediated demethylation, thereby attenuating ferroptosis induced by irradiation and promoting NPC radioresistance.

Esophageal cancer global burden profiles, trends, and contributors.

OBJECTIVE: This study aimed to provide a comprehensive overview of the global burden of esophageal cancer (EC) and determine the temporal trends and factors influencing changes in the global burden. METHODS: The latest incidence and mortality data for EC worldwide were obtained from GLOBALCAN 2022. The mortality and disability-adjusted life years (DALYs) rates for EC from 1990-2019 were sourced from the 2019 Global Burden of Diseases. Trends in EC mortality and DALYs attributable to 11 risk factors or clusters of risk were analyzed using the joinpoint regression model. The trends in age-related EC burden were assessed using a decomposition approach. RESULTS: An estimated 511,054 new cases of EC were diagnosed in 2022 with 445,391 deaths worldwide. Approximately 75% of cases and deaths occurred in Asia. Nearly 50% of global EC deaths and DALYs were attributed to tobacco use in men in 2019, while 20% were attributed to high body mass index (BMI) in women. From 1990-2019, EC deaths and DALYs attributable to almost all risk factors had declining trends, while EC deaths and DALYs attributed to high BMI in men had upward trends. The age-related EC burden exhibited an upward trend driven by population growth and aging, which contributed to 307.4 thousand deaths and 7.2 million DALYs due to EC. CONCLUSIONS: The EC burden remains substantial worldwide. Effective tobacco and obesity control measures are critical for addressing the risk-attributable burden of EC. Population growth and aging pose challenges for EC prevention and control efforts.

Attributable liver cancer deaths and disability-adjusted life years in China and worldwide: profiles and changing trends.

OBJECTIVE: Liver cancer is a major health concern globally and in China. This analysis investigated deaths and disability-adjusted life years (DALYs) with respect to etiologies and risk factors for liver cancer in China and worldwide. METHODS: Global and China-specific data were collected on liver cancer deaths, DALYs, and age-standardized rates (ASRs) from the Global Burden of Disease Study 2019 database. Liver cancer etiologies were classified into five groups and risk factors were categorized into three levels. Each proportion of liver cancer burden was calculated in different geographic regions. The joinpoint regression model were used to assess the trends from 1990-2019. RESULTS: Liver cancer accounted for 484,577 deaths worldwide in 2019 with an ASR of 5.9 per 100,000 population. China had an elevated liver cancer death ASR in 2019 and males had an ASR 1.7 times the global rate. The global ASR for DALYs peaked at 75-79 years of age but peaked earlier in China. Hepatitis B virus was the prominent etiology globally (39.5%) and in China (62.5%), followed by hepatitis C virus and alcohol consumption. In high sociodemographic index countries, non-alcoholic steatohepatitis has gained an increasing contribution as an etiologic factor. The liver cancer burden due to various etiologies has decreased globally in both genders. However, metabolic risk factors, particularly obesity, have had a growing contribution to the liver cancer burden, especially among males. CONCLUSIONS: Despite an overall decreasing trend in the liver cancer burden in China and worldwide, there has been a rising contribution from metabolic risk factors, highlighting the importance of implementing targeted prevention and control strategies that address regional and gender disparities.

Personalized starting age of gastric cancer screening based on individuals' risk profiles: a population-based prospective study.

BACKGROUND: The current recommended starting age for gastric cancer (GC) lacks unified guideline and individualized criteria. We aimed to determine risk-stratified starting age for GC screening in China based on individuals' risk profiles, and develop an online calculator for clinical application. METHODS: In this multi-center population-based prospective study, we divided participants enrolled during 2015-2017 (n = 59,771, aged 40-69) into screened and unscreened groups and observed them for primary endpoints-GC occurrence, all-cause and GC-specific deaths. The median follow-up was 6.07 years. To determine the reference starting age, the effectiveness of GC screening was assessed by age-groups after propensity-score-matching. Further, we categorized the calculated individual risk scores (using well-established risk factors) by quantiles. Subsequently, we used age-specific 10-year cumulative risk curves to estimate the risk-stratified starting age-when the individual's risk level matches reference starting age risk threshold. RESULTS: During follow-up, 475 GC cases, 182 GC deaths and 1,860 all-cause deaths occurred. All-cause and GC-specific mortality decreased among screened individuals aged ≥45 and 50-59 years, respectively. Thus, the average population (reference) starting age was set as 50 years. The 10-year cumulative risk of GC in average population aged 50 was 1.147%. We stratified the starting age using eight risk factors, and categorized participants as low-, medium-, and high-risk individuals, whose risk-stratified starting age was 58, 50, and 46, respectively. CONCLUSION: While high-risk individuals warrant 3-5 years earlier GC screening than average population (age 50), low-risk individuals can tolerate delayed screening. Our online, personalized starting-age calculator will help risk-adapted GC screening (https://web.consultech.com.cn/gastric/#/).

The current infection with Helicobacter pylori and association with upper gastrointestinal lesions and risk of upper gastrointestinal cancer: Insights from multicenter population-based cohort study.

The relationship between Helicobacter pylori (H. pylori) infection and upper gastrointestinal (UGI) cancers is complex. This multicenter, population-based cohort study conducted in seven areas in China aimed to assess the correlation between current H. pylori infection and the severity of UGI lesions, as well as its association with the risk of gastric cancer (GC) and esophageal cancer (EC). From 2015 to 2017, 27,085 participants (aged 40-69) completed a standardized questionnaire, and underwent a 13C-urea breath test. Then a subset underwent UGI endoscopy to assess the UGI lesion detection rates. All individuals were followed up until December 2021 to calculate the hazard ratios (HRs) for UGI cancers. H. pylori infection prevalence was 45.9%, and among endoscopy participants, 22.2% had gastric lesions, 19.2% had esophageal lesions. Higher detection rates of gastric lesions were noted in the H. pylori-positive population across all lesion severity levels. Over a median follow-up of 6.3 years, 104 EC and 179 GC cases were observed, including 103 non-cardia gastric cancer (NCGC) cases and 76 cardia gastric cancer (CGC) cases. H. pylori-infected individuals exhibited a 1.78-fold increased risk of GC (HR 1.78, 95% confidence interval [CI] 1.32-2.40) but no significant increase in EC risk (HR 1.07, 95% CI 0.73-1.57). Notably, there was a higher risk for both NCGC and CGC in H. pylori-infected individuals. This population-based cohort study provides valuable evidence supporting the association between current H. pylori infection and the risk of both NCGC and CGC. These findings contribute to the empirical basis for risk stratification and recommendations for UGI cancer screening.

Benefits and harms of polygenic risk scores in organised cancer screening programmes: a cost-effectiveness analysis.

Background: While polygenic risk scores (PRS) could enable the streamlining of organised cancer screening programmes, its current discriminative ability is limited. We conducted a cost-effectiveness analysis to trade-off the benefits and harms of PRS-stratified cancer screening in China. Methods: The validated National Cancer Center (NCC) modelling framework for six cancers (lung, liver, breast, gastric, colorectum, and oesophagus) was used to simulate cancer incidence, progression, stage-specific cancer detection, and risk of death. We estimated the number of cancer deaths averted, quality-adjusted life-years (QALY) gained, number needed to screen (NNS), overdiagnosis, and incremental cost-effectiveness ratio (ICER) of one-time PRS-stratified screening strategy (screening 25% of PRS-defined high-risk population) for a birth cohort at age 60 in 2025, compared with unstratified screening strategy (screening 25% of general population) and no screening strategy. We applied lifetime horizon, societal perspective, and 3% discount rate. An ICER less than $18,364 per QALY gained is considered cost-effective. Findings: One-time cancer screening for population aged 60 was the most cost-effective strategy compared to screening at other ages. Compared with an unstratified screening strategy, the PRS-stratified screening strategy averted more cancer deaths (61,237 vs. 40,329), had a lower NNS to prevent one death (307 vs. 451), had a slightly higher overdiagnosis (14.1% vs. 13.8%), and associated with an additional 130,045 QALYs at an additional cost of $1942 million, over a lifetime horizon. The ICER for all six cancers combined was $14,930 per QALY gained, with the ICER varying from $7928 in colorectal cancer to $39,068 in liver cancer. ICER estimates were sensitive to changes in risk threshold and cost of PRS tools. Interpretation: PRS-stratified screening strategy modestly improves clinical benefit and cost-effectiveness of organised cancer screening programmes. Reducing the costs of polygenic risk stratification is needed before PRS implementation.

ZNF148 inhibits HBV replication by downregulating RXRα transcription.

BACKGROUND: Progressive hepatitis B virus (HBV) infection can result in cirrhosis, hepatocellular cancer, and chronic hepatitis. While antiviral drugs that are now on the market are efficient in controlling HBV infection, finding a functional cure is still quite difficult. Identifying host factors involved in regulating the HBV life cycle will contribute to the development of new antiviral strategies. Zinc finger proteins have a significant function in HBV replication, according to earlier studies. Zinc finger protein 148 (ZNF148), a zinc finger transcription factor, regulates the expression of various genes by specifically binding to GC-rich sequences within promoter regions. The function of ZNF148 in HBV replication was investigated in this study. METHODS: HepG2-Na+/taurocholate cotransporting polypeptide (HepG2-NTCP) cells and Huh7 cells were used to evaluate the function of ZNF148 in vitro. Northern blotting and real-time PCR were used to quantify the amount of viral RNA. Southern blotting and real-time PCR were used to quantify the amount of viral DNA. Viral protein levels were elevated, according to the Western blot results. Dual-luciferase reporter assays were used to examine the transcriptional activity of viral promoters. ZNF148's impact on HBV in vivo was investigated using an established rcccDNA mouse model. RESULTS: ZNF148 overexpression significantly decreased the levels of HBV RNAs and HBV core DNA in HBV-infected HepG2-NTCP cells and Huh7 cells expressing prcccDNA. Silencing ZNF148 exhibited the opposite effects in both cell lines. Furthermore, ZNF148 inhibited the activity of HBV ENII/Cp and the transcriptional activity of cccDNA. Mechanistic studies revealed that ZNF148 attenuated retinoid X receptor alpha (RXRα) expression by binding to the RXRα promoter sequence. RXRα binding site mutation or RXRα overexpression abolished the suppressive effect of ZNF148 on HBV replication. The inhibitory effect of ZNF148 was also observed in the rcccDNA mouse model. CONCLUSIONS: ZNF148 inhibited HBV replication by downregulating RXRα transcription. Our findings reveal that ZNF148 may be a new target for anti-HBV strategies.

Cancer profiles in China and comparisons with the USA: a comprehensive analysis in the incidence, mortality, survival, staging, and attribution to risk factors.

China faces a disproportionate cancer burden to the population size and is undergoing a transition in the cancer spectrum. We extracted data in five aspects of cancer incidence, mortality, survival, staging distributions, and attribution to risk factors in China, the USA and worldwide from open-source databases. We conducted a comprehensive secondary analysis of cancer profiles in China in the above aspects, and compared cancer statistics between China and the USA. A total of 4,546,400 new cancer cases and 2,992,600 deaths occurred in China in 2020, accounting for 25.1% and 30.2% of global cases, respectively. Lifestyle-related cancers including lung cancer, colorectal cancer, and breast cancer showed an upward trend and have been the leading cancer types in China. 41.6% of new cancer cases and 49.3% of cancer deaths occurred in digestive-system cancers in China, and the cancers of esophagus, nasopharynx, liver, and stomach in China accounted for over 40% of global cases. Infection-related cancers showed the highest population-attributable fractions among Chinese adults, and most cancers could be attributed to behavioral and metabolic factors. The proportions of stage I for most cancer types were much higher in the USA than in China, except for esophageal cancer (78.2% vs. 41.1%). The 5-year relative survival rates in China have improved substantially during 2000-2014, whereas survival for most cancer types in the USA was significantly higher than in China, except for upper gastrointestinal cancers. Our findings suggest that although substantial progress has been made in cancer control, especially in digestive system cancers in China, there was still a considerable disparity in cancer burden between China and the USA. More robust policies on risk factors and standardized screening practices are urgently warranted to curb the cancer growth and improve the prognosis for cancer patients.

Cancer statistics for young adults aged 20 to 49 years in China from 2000 to 2017: a population-based registry study.

An increasing cancer incidence among adults younger than 50 years has been reported for several types of cancer in multiple countries. We aimed to report cancer profiles and trends among young adults in China. Data from the China Cancer Registry Annual Report were used to estimate incidence and mortality among young adults (ages 20-49 years) in China in 2017, and an age-period-cohort model was employed to estimate the average annual percent change (AAPC) in incidence and mortality from 2000 to 2017. All 25 cancer types were grouped into obesity- or overweight-associated cancers (12 cancer types) and additional cancers (13 cancer types). In 2017, there were 681,178 new cases and 214,591 cancer deaths among young adults in China. Among young adults, the most common cancers were thyroid, breast, cervical, liver, lung, and colorectal cancer, and the leading causes of cancer deaths were liver, lung, cervical, stomach, breast, and colorectal cancer. From 2000 to 2017, the cancer incidence increased for all cancers combined among young adults, with the highest AAPC (1.46%) for adults aged 20-24 years, while cancer mortality decreased, with the highest AAPC (-1.63%) for those aged 35-39 years. In conclusion, the cancer incidence in China has increased among young adults, while cancer mortality has decreased for nearly all ages. Cancer control measures, such as obesity control and appropriate screening, may contribute to reducing the increasing cancer burden among young adults.

Long-term esophageal cancer risk and distinct surveillance intervals after a single endoscopy screening: a multicentre population-based cohort study.

Background: Endoscopy surveillance is recommended for mild-moderate dysplasia and negative endoscopy findings every 3 years and 5 years, respectively, but evidence is limited. This study aimed to assess long-term esophageal cancer (EC) incidence and mortality after a single endoscopy screening. Methods: We included individuals at high risk of EC aged 40-69 years who underwent endoscopy screening in 2007-2012 at six centres in rural China and had a baseline diagnosis of negative endoscopy findings, mild dysplasia, or moderate dysplasia. Participants were followed up for EC incidence and mortality. Cumulative incidence and mortality rates of EC were estimated by Kaplan-Meier analyses. Cox regression models were used to calculate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between baseline endoscopy diagnosis and the risk of EC incidence and mortality. EC incidence and mortality after a single endoscopy screening were compared with those of the population in rural China by the standardized incidence ratio (SIR) and standardized mortality ratio (SMR). Findings: A total of 42,827 participants (40,977 with negative endoscopy findings, 1562 with mild dysplasia, and 288 with moderate dysplasia) were included; 268 EC cases and 128 EC deaths were identified during a median follow-up of 10.62 years. The cumulative EC incidence at 10 years was 0.45% (0.38-0.52) in the group with negative endoscopy findings, 2.39% (1.62-3.16) in the mild dysplasia group, and 8.90% (5.57-12.24) in the moderate dysplasia group, and the cumulative EC mortality at 10 years was 0.23% (0.18-0.27), 0.96% (0.46-1.46), and 2.50% (0.67-4.33), respectively. Compared with individuals with negative endoscopy findings, the HRs for EC incidence and mortality in the mild dysplasia group were 3.52 (2.49-4.97) and 2.43 (1.41-4.19), and those in the moderate dysplasia group were 13.18 (8.78-19.76) and 6.46 (3.13-13.29), respectively. The SIR was 0.53 (0.40-0.70) for the group with negative endoscopy findings, 1.95 (1.69-2.24) for the mild dysplasia group, and 6.75 (6.25-7.28) for the moderate dysplasia group, with the SMRs of 0.43 (0.31-0.58), 1.07 (0.88-1.29) and 2.67 (2.36-3.01), respectively. Interpretation: Individuals with negative endoscopy findings after a single endoscopy screening had a lower EC risk than the general population for up to 10.62 years, while those with mild-moderate dysplasia had an elevated risk. Our results support endoscopy surveillance for mild-moderate dysplasia every 3 years and suggest extending the interval to 10 years after a negative endoscopy finding.

Global patterns of cancer transitions: A modelling study.

Cancer is a major contributor to global disease burden. Many countries experienced or are experiencing the transition that non-infection-related cancers replace infection-related cancers. We aimed to characterise burden changes for major types of cancers and identify global transition patterns. We focused on 10 most common cancers worldwide and extracted age-standardised incidence and mortality in 204 countries and territories from 1990 to 2019 through the Global Burden of Disease Study. Two-stage modelling design was used. First, we applied growth mixture models (GMMs) to identify distinct trajectories for incidence and mortality of each cancer type. Next, we performed latent class analysis to detect cancer transition patterns based on the categorisation results from GMMs. Kruskal-Wallis H tests were conducted to evaluate associations between transition patterns and socioeconomic indicators. Three distinct patterns were identified as unfavourable, intermediate and favourable stages. Trajectories of lung and breast cancers had the strongest association with transition patterns among men and women. The unfavourable stage was characterised by rapid increases in lung, breast and colorectal cancers alongside stable or decreasing burden of gastric, cervical, oesophageal and liver cancers. In contrast, the favourable stage exhibited rapid declines in most cancers. The unfavourable stage was associated with lower sociodemographic index, health expenditure, gross domestic product per capita and higher maternal mortality ratio (P < .001 for all associations). Our findings suggest that unfavourable, intermediate and favourable transition patterns exist. Countries and territories in the unfavourable stage tend to be socioeconomically disadvantaged, and tailored intervention strategies are needed in these resource-limited settings.

Occurrence and influencing factors of cyclosporine A on the kidney injury following allogeneic hematopoietic stem cell transplantation: A systematic review and meta-analysis.

OBJECTIVE: Whether cyclosporine A (CsA) is a risk factor of kidney injury after allogeneic hematopoietic stem cell transplantation (allo-HSCT) has not been determined. We aim to comprehensively review the correlation and influencing factors between CsA and kidney injury in patients following allo-HSCT. METHODS: We searched PubMed, Embase (Ovid), Cochrane Central Register of Controlled Trials (CENTRAL), CNKI, VIP, Wanfang and CBM Database from inception to March 2022. Two researchers independently conducted literature screening, data extraction and quality assessment. Qualitative and quantitative methods were combined to analyze the data. RESULTS: We included a total of 30 studies. Meta-analyses of total incidence of kidney injury related to CsA was 37.0% [95% CI (25.4%, 48.6%); n = 15]. The proportion of CsA-related acute kidney injury to total acute kidney injury following allo-HSCT was 59.7% [95% CI (49.1%, 70.3%); n = 9]. One study found that AKI had a significant association with CsA in multivariate analysis [RR = 6.173; 95% CI (4.032, 9.434)]. With respect to cyclosporine combination and nephrotoxicity, 6/9 studies demonstrated that the concomitant medications for CsA (especially aminoglycoside antibiotics and amphotericin B) had negative effect on kidney functions related to CsA in allo-HSCT patients. No consensus was reached for "dose of CsA", "duration of CsA use", "comorbidities" and "CsA levels" across studies. CONCLUSIONS: CsA may be a risk factor for kidney injury in patients following allo-HSCT, especially the concomitant use of CsA and nephrotoxic medications.

Profiles and Findings of Population-Based Esophageal Cancer Screening With Endoscopy in China: Systematic Review and Meta-analysis.

BACKGROUND: Population-based esophageal cancer (EC) screening trials and programs have been conducted in China for decades; however, screening strategies have been adopted in different regions and screening profiles are unclear. OBJECTIVE: We performed a meta-analysis to profile EC screening in China by positivity rate, compliance rate, and endoscopy findings, aiming to provide explicit evidence and recommendations for EC screening programs. METHODS: English (PubMed, Embase) and Chinese (China National Knowledge Infrastructure, Wanfang) language databases were systematically searched for population-based EC screening studies in the Chinese population until December 31, 2022. A meta-analysis was performed by standard methodology using a random-effects model. Pooled prevalence rates were calculated for three groups: high-risk areas with a universal endoscopy strategy, rural China with a risk-stratified endoscopic screening (RSES) strategy, and urban China with an RSES strategy. Positive cases included lesions of severe dysplasia, carcinoma in situ, intramucosal carcinoma, submucosal carcinoma, and invasive carcinoma. RESULTS: The pooled positivity rate of the high-risk population was higher in rural China (44.12%) than in urban China (23.11%). The compliance rate of endoscopic examinations was the highest in rural China (52.40%), followed by high-risk areas (50.11%), and was the lowest in urban China (23.67%). The pooled detection rate of positive cases decreased from 1.03% (95% CI 0.82%-1.30%) in high-risk areas to 0.48% (95% CI 0.25%-0.93%) in rural China and 0.12% (95% CI 0.07%-0.21%) in urban China. The pooled detection rate of low-grade intraepithelial neoplasia (LGIN) was also in the same order, being the highest in high-risk areas (3.99%, 95% CI 2.78%-5.69%), followed by rural China (2.55%, 95% CI 1.03%-6.19%) and urban China (0.34%, 95% CI 0.14%-0.81%). Higher detection rates of positive cases and LGIN were observed among males than among females and at older ages. The pooled early detection rate was 81.90% (95% CI 75.58%-86.88%), which was similar to the rates in high-risk areas (82.09%), in rural China (80.76%), and in urban China (80.08%). CONCLUSIONS: Under the current screening framework, a higher screening benefit was observed in high-risk areas than in other regions. To promote EC screening and reduce the current inequality of screening in China, more focus should be given to optimizing strategies of high-risk individual assessment and surveillance management to improve compliance with endoscopic examination.

Stomach cancer burden in China: Epidemiology and prevention.

In 2020, stomach cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death worldwide. Due to the relatively huge population base and the poor survival rate, stomach cancer is still a threat in China, and accounts for nearly half of the cases worldwide. Fortunately, in China, the incidence and mortality rates of stomach cancer presented a declining trend owing to the change of individual life styles and the persistent efforts to prevent stomach cancer from the governments at all levels. Helicobacter pylori (H. pylori) infection, poor eating habits, smoking, history of gastrointestinal disorders, and family history of stomach cancer are the main risk factors for stomach cancer in China. As a result, by taking risk factors for stomach cancer into account, specific preventive measures, such as eradicating H. pylori and implementing stomach cancer screening projects, should be taken to better prevent and decrease the burden of stomach cancer.

Global trajectories of liver cancer burden from 1990 to 2019 and projection to 2035.

BACKGROUND: Large disparities exist in liver cancer burden trends across countries but are poorly understood. We aimed to investigate the global trajectories of liver cancer burden, explore the driving forces, and predict future trends. METHODS: Data on the liver cancer burden in 204 countries and territories from 1990 to 2019 were extracted from the Global Burden of Disease Study. The age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) trajectories were defined using growth mixture models. Five major risk factors contributing to changes in the ASIR or ASMR and socioeconomic determinants were explored using the identified trajectories. A Bayesian age-period-cohort model was used to predict future trends through 2035. RESULTS: Three trajectories of liver cancer burden were identified: increasing, stable, and decreasing groups. Almost half of the American countries were classified in the decreasing group (48.6% for ASIR and ASMR), and the increasing group was the most common in the European region (ASIR, 49.1%; ASMR, 37.7%). In the decreasing group, the decrease of liver cancer due to hepatitis B contributed 63.4% and 60.4% of the total decreases in ASIR and ASMR, respectively. The increase of liver cancer due to alcohol use, hepatitis C, and hepatitis B contributed the most to the increase in the increasing group (30.8%, 31.1%, and 24.2% for ASIR; 33.7%, 30.2%, and 22.2% for ASMR, respectively). The increasing group was associated with a higher sociodemographic index, gross domestic product per capita, health expenditure per capita, and universal health coverage (all P <0.05). Significant variations in disease burden are predicted to continue through 2035, with a disproportionate burden in the decreasing group. CONCLUSION: Global disparities were observed in liver cancer burden trajectories. Hepatitis B, alcohol use, and hepatitis C were identified as driving forces in different regions.

Efficacy of Hemoperfusion Cartridge Procedure on Patients Undergoing Cardiac Valve Replacement Surgery with Cardiopulmonary Bypass.

OBJECTIVES: Cardiopulmonary bypass (CPB) induces inflammatory homeostasis dysregulation, closely related to many postoperative adverse effects. Minimizing the systemic inflammatory response to CPB is imperative to improving cardiac surgery safety. This study aimed to retrospectively evaluate the efficacy of the hemoperfusion cartridge, a device recently designed for extracorporeal blood purification to remove cytokines from the blood for patients undergoing cardiac valve replacement surgery using CPB. METHODS: The hemoperfusion (HP) group consisted of 138 patients, who underwent a hemoperfusion cartridge procedure during CPB. The control group included 149 patients, who received standard CPB management. The evaluated indices included inflammatory cytokines, blood biochemical indices, and postoperative outcome indices. RESULTS: Patients in the HP group had relatively lower interleukin (IL)-6 levels (days one and two post-CPB) and IL-8 (day one post-CPB) compared with the control group. Some relatively decreased biochemical blood indices also were observed in the HP group, including a significantly lower lactic acid level (days one, two, and three post-CPB), platelet counts (days one, two, and three post-CPB), and aspartate aminotransferase (days one and three post-CPB). Regarding the postoperative outcomes, no severe complications occurred in the patients; however, the HP group required less ventilation time than the control group. CONCLUSIONS: The hemoperfusion cartridge seems promising in limiting the inflammatory reactions during CPB, with noteworthy potential for application in cardiac surgery.
