Liver cancer is a significant global disease burden with a major impact on population health,and it is one of the important concerns in terms of public health worldwide.Cancer risk prediction models can estimate an individual's absolute risk of developing cancer.Individual risk assessment allows targeted screening of high-risk populations,which is essential for primary and secondary cancer prevention.In this review,we examine existing epidemiological studies to explore key issues in the design,predictive variables,and performance of risk prediction models for liver cancer in the general population.The aim is to provide an important reference for the future development of highly comprehensive liver cancer risk prediction models.

The relationship between the duration of type 2 diabetes mellitus (T2DM) and the risk of female reproductive malignancies is complex and multifaceted. Large population cohort studies revealed a negative association between the duration of T2DM and the incidence of breast cancer and endometrial cancer. Furthermore, the risk of breast and endometrial cancer is the highest within a short time after T2DM diagnosis and remains remarkably higher in patients with longer diabetes duration than in the nondiabetic population. This phenomenon suggests causal reverse bias and potential detection bias. Nevertheless, T2DM remains an important risk factor for breast and endometrial cancer. Research on the association between diabetes with cervical and ovarian cancer is limited, and results vary by region. Future epidemiological studies should focus on large prospective studies with long follow-up to further investigate this association. Research into the biological mechanisms linking diabetes and female reproductive cancers is also necessary to develop effective cancer prevention and early intervention strategies.

Objective To analyze the colorectal cancer screening of community residents in Pudong New Area in Shanghai and provide reference for the promotion and strategy optimization of colorectal cancer screening programs. Methods Residents aged 50-74 years in the colorectal cancer screening project of Pudong New Area in Shanghai from 2013 to 2023 were recruited in this analysis. The situation of primary screening and colonoscopy in the community was described, and results of different age groups in primary screening and colonoscopy surveys were evaluated. Chi-square test was used to determine differences between groups. Results From 2013 to 2023, 907 030 residents were screened in Pudong New Area, of which 183 724 residents were positive, and the positive rate was 20.3%. The positive rate was the lowest in the 50-54 age group and the highest in the 70-74 age group. The positive rate was higher in men than in women. The overall colonoscopy rate was 27.1%, with the highest rates in the 50-54 age group in men and the 55-59 age group in women, respectively. The participation rate of colonoscopy increased with the increase of the year. A total of 19 094 cases of intestinal lesions were found by colonoscopy. Among these lesions, 1 147 cases were colorectal cancer, accounting for 6.0%, and the population detection rate was 126.5/100 000. In addition, 4 751 cases of precancerous lesions were found, accounting for 24.9%, and the detection rate was 523.8/100 000. Conclusion Colorectal cancer screening improves the detection rate of precancerous lesions and early cancer and is of great significance for reducing the incidence and mortality of colon cancer. Measures should be taken to optimize the screening strategy based on age differences and increase the participation rate of primary screening and colonoscopy to achieve the best effect of local colorectal cancer prevention and treatment.

Objective: To analyze the association between dietary inflammatory index (DII) and gallstone disease among middle-aged and elderly population, so as to provide the evidence for the prevention and control of gallstone disease. Methods: Baseline survey data were collected from the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS), including demographic information, gallstone disease prevalence and dietary habits. DII was calculated using 29 kinds of food parameters associated with common inflammatory biomarkers and food intake data of residents. A multivariable logistic regression model was used to analyze the association between dietary inflammatory index and gallstone disease. Results: A total of 132 312 individuals were included in the analysis. There were 59 627 males and 72 685 females. Among males, the median age was 53.07 (interquartile range, 9.73) years, 41 544 cases (69.67%) had an educational level of middle school, 4 463 cases (7.48%) had gallstone disease, and DII was -6.46 to 5.59. Among females, the median age was 50.27 (interquartile range, 9.05) years, 47 380 cases (65.19%) had an educational level of middle school, 8 090 cases (11.13%) had gallstone disease, and DII was -6.44 to 4.93. Multivariable logistic regression analysis showed that after adjusting for age, educational level, income level, smoking, alcohol consumption, tea consumption, physical activity and menopausal status (only for females), DII (OR=1.095, 95%CI: 1.002-1.196) was associated with an increased risk of gallston disease among males, but no statistically association was found among females (P>0.05). Conclusion DII might be associated with an increased risk of gallstone disease among middle-aged and elderly population.

Objectives:To analyze the status and temporal changes of disability-adjusted life year (DALY) for stomach and colorectal cancers among registered permanent residents in Changning District of Shanghai Municipality, and provide scientific basis for the prevention and treatment of stomach and colorectal cancers in this district.Methods:Using the cancer registration data of stomach and colorectal cancers from 2002 to 2019, we estimated the indices such as the DALYs, the DALY crude rates, the age-standardized DALY rates, etc. Then we used the Joinpoint regression model to calculate the average annual percent change (AAPC) and annual percent change (APC) to explore the temporal variations in different periods.Results:The DALYs of stomach and colorectal cancers in Changning District from 2002 to 2019 were 55 931 person years and 65 252 person years, respectively. The crude rates of DALY were 512.16/10 5 and 597.51/10 5, respectively. We observed a higher disease burden in men than in women, and the peak rate of DALY in stomach cancer was in the 75-79 years age group, while in colorectal cancer the rate was in the 85-years-or-older age group. Joinpoint regression analysis showed that from 2002 to 2019, the age-standardized DALY rate of stomach cancer showed a downward trend (AAPC=-3.86%, P＜0.05), while the trend of colorectal cancer was not statistically significant(AAPC=-0.08%, P＞0.05). However, the trends in the age-standardized DALY rates of colorectal cancer were different between males and females, with males showing an upward trend (AAPC=1.24%, P＜0.05) and females showing a downward trend (AAPC=-1.67%, P＜0.05). Conclusions:The DALY of stomach and colorectal cancers in Changning District of Shanghai showed a decreasing trend. Males and the middle-aged and elderly populations are still the key targets for disease prevention and control in this district.

Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

Metabolites,as the end products of biochemical reactions within organisms,directly reflect the interplay of gene expression,protein function,and environmental factors,offering a comprehensive reflection of the organism's response to inherent genetic variations and external environmental changes.By systematically analyzing changes in human metabolite profiles,metabolomics aids in the identification of potential biomarkers,offering new insights for the early diagnosis,prevention,and personalized treatment of diseases.In recent years,research method-ologies in metabolomics have increasingly been applied to the etiological studies of liver cancer.This paper aims to review existing research reports to understand the application of metabolomics in the study of liver cancer etiology,with a focus on high-level evidence from prospective cohort studies and case-control studies nested within cohorts.By summarizing the current research evi-dence,the paper aims to advance the study of the etiological mechanisms of liver cancer,under-stand the pathogenic mechanisms of known risk factors,and offer a scientific foundation for the prediction of liver cancer.

BACKGROUND: Biliary tract carcinomas (BTCs) are relatively rare but lethal primary malignant tumors derived from the biliary tract system. The burden of BTCs varies according to sex, age, region, and country, but limited attention has been paid to the burden of BTCs. We sought to explore the up-to-date data from the Global Burden of Disease Study (GBD) and expand findings by accessing the demographic features of BTC disease burden. METHODS: Using the latest data from the GBD 2021, we evaluated and analyzed the distributions and patterns of BTC disease burden in various age groups, sexes, regions, and countries. RESULTS: The number of incident cases, deaths, and disability-adjusted life-years (DALYs) tended to increase and peaked at 216,770 (95% uncertainty interval [UI]: 181,890-245,240), 171,960 (95% UI: 142,350-194,240), and 3,732,100 (95% UI: 3,102,900-4,317,000) person-years, respectively, in 2021. However, the average global age-standardized rates (ASRs) of incident cases, deaths, and DALYs shrunk by -11.46% (95% UI: -21.91 to 3.35%), -24.09% (95% UI: -33.19 to 16.88%), and -26.25% (95% UI: -35.53 to 18.36%), respectively, from 1990 to 2021. Meanwhile, the male/female ratio (male per 100 female) of incidence, deaths, and DALYs changed from 76.40, 75.41, and 74.72 to 86.89, 79.11, and 82.29, respectively. In 2021, the highest number of incident cases, deaths, and DALYs occurred in East Asia. The top three highest incidences, deaths, and DALYs were observed in China, India, and Japan, and the highest ASRs were observed in Chile in 2021. Analysis of the Human Development Index along with disease burden estimates of BTCs also suggests that the burden of the disease is related to the level of comprehensive development of the society. CONCLUSION This study provided a comprehensive comparison of differences in the burden of disease across populations and over time, and further presented evidence concerning the formulation of prevention and control policies and etiologic studies for BTCs and proposed logical hypotheses to investigate.
