Incidence Rate Of Liver Cancer Research Articles

Trend analysis and age-period-cohort effects on morbidity and mortality of liver cancer from 2010 to 2020 in Guangzhou, China.

Liver cancer is one of the most common malignant gastrointestinal tumors worldwide. This study intends to provide insight into the epidemiological characteristics and development trends of liver cancer incidence and mortality from 2010 to 2020 in Guangzhou, China. Data were collected from the Cancer Registry and Reporting Office of Guangzhou Center for Disease Control and Prevention. Cross-sectional study, Joinpoint regression (JPR) model, and Age-Period-Cohort (APC) model were conducted to analyze the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) trend of liver cancer among the entire study period. The age-standardized incidence and mortality of liver cancer in Guangzhou showed an overall decreasing trend. The disparity in risk of morbidity and mortality between the two sexes for liver cancer is increasing. The cohort effect was the most significant among those born in 1965~1969, and the risk of liver cancer incidence and mortality in the total population increased and then decreased with the birth cohort. Compared with the birth cohort born in 1950~1954 (the reference cohort), the risk of liver cancer incidence and mortality in the males born in 1995~1999 decreased by 32% and 41%, respectively, while the risk in the females decreased by 31% and 32%, respectively. The early detection, prevention, clinical diagnosis, and treatment of liver cancer in Guangzhou have made remarkable achievements in recent years. However, the risk of liver cancer in the elderly and the middle-aged males is still at a high level. Therefore, the publicity of knowledge related to the prevention and treatment of liver cancer among the relevant population groups should be actively carried out to enhance the rate of early diagnosis and treatment of liver cancer and to advocate a healthier lifestyle.

Global association of incidence between atrial fibrillation and the major gastrointestinal cancers: An analysis based on the 2019 Global burden of disease study

Atrial Fibrillation (AF) and gastrointestinal (GI) cancers are age-related diseases with shared environmental risk factors and underlying biological mechanisms. This study aimed to assess the association between AF and GI cancers on a global scale, analyzing incidence data from 204 countries. This ecological study utilized data from the Global Burden of Disease. Spearman's correlation and logistic regression analyses were employed to assess the association between AF and specific GI cancers, including esophagus cancer (EC), colon and rectum cancer (CRC), liver cancer (LC), pancreatic cancer (PC), and stomach cancer (SC). AF, CRC and PC exhibited increasing crude incidence rates from 2000 to 2019, whereas EC and SC demonstrated decreasing trends specifically in females. From 2000 to 2010, there was a noticeable fall in the incidence rate of LC, which was followed by a minor growth through 2019. The age-standardized incidence rate (ASIR) of AF was positively correlated with CRC and PC, but a negative relationship with AF was revealed for EC. Unexpectedly, no significant relationship was discovered for SC and LC associated with AF. Logistic regression analysis revealed a positive correlation between a country's ASIR of AF and its ASIR of CRC, LC and PC. Conversely, these countries demonstrated a decreased ASIR for EC. Our findings showed a significant correlation between national incidence rates of AF with CRC and PC, worldwide. Countries with higher ASIR of AF had higher ASIR of CRC and PC. Additional research is necessary to confirm the association between GI cancers and AF at the individual level.

Incidence of liver cancer in young adults according to the global burden of disease database 2019.

The worldwide burden of cancer is increasing in younger populations. However, the epidemiology of primary liver cancer remains understudied in young adults compared to other cancer forms. This study analyzed data from the Global Burden of Disease (GBD) study between 2010 and 2019 to assess the age-standardized incidence, mortality, and disability-adjusted life years (DALYs) associated with primary liver cancer in the young (15-49y), stratified by region, nation, sociodemographic index, and sex. The study found a global estimate of 78,299 primary liver cancer cases, 60,602 deaths, and 2.90 million DALYs in the young population. The Western Pacific region exhibited the highest burden in 2019, showing the most significant increase compared to other regions between 2010-2019. More than half of countries worldwide have undergone an increase in primary liver cancer incidence rates in young adults. Around 12.51% of deaths due to primary liver cancer occur in young individuals. Throughout the study period, there was a significant decline in primary liver cancer mortality due to most etiologies, except for metabolic dysfunction-associated steatotic liver disease (MASLD)-attributable primary liver cancer (annual percentage change [APC] +0.87%, 95% confidence interval 0.70-1.05%) and alcohol-attributable primary liver cancer (APC +0.21%, 95% confidence interval 0.01-0.42%). Limitations of the GBD database include reliance on the quality of primary data and possible underestimation of alcohol consumption. Over the past decade, there has been a marked increase in the burden of primary liver cancer, especially that originating from steatotic liver disease. This trend calls for the development of urgent and comprehensive strategies to mitigate this rising burden globally.

Abstract 5729: ADCK1 inhibition alters cell proliferation and cell cycle progression in liver cancer cells

Abstract In 2020, there were over 830,000 reported liver cancer deaths. Incidence rates of liver cancer have tripled, and death rates have doubled since the 1980s; giving this disease one of the highest mortality rates when compared to its incidence rate. Hepatocellular carcinoma (HCC) is derived from hepatocytes and is the main type of liver cancer in adults, accounting for 75-85% of all primary liver cancers. Current treatment options for HCC like radiation therapy and chemotherapy are imperfect and cause significant side effects. Tumorigenesis is dependent on an organism’s cellular metabolism. Metabolic reprogramming is a promising area of focus for cancer therapeutics. Cancer cells thrive in nutrient-deficient environments by hijacking and reprogramming the cells existing cellular metabolism. Metabolic reprogramming is driven by genetic alterations and environmental cues. AarF Domain Containing Kinase 1 (ADCK1) is a protein-coding gene that acts as a mitochondrial protein with putative kinase activity. The role of ADCK1 has not been well studied, particularly in liver cancer. Our group has sought to study how ADCK1 impacts the metabolism and cellular environment of HCC cells to help establish a more effective drug target. Bioinformatics performed by our lab report that ADCK1 was highly expressed in HCC tumor cells. The expression levels of ADCK1 were also correlated with a decrease in patient survival. ADCK1 knockout clones were generated; these knockout cells showed decreased proliferation and altered cell cycle progression. Proteomics analysis demonstrated that loss of ADCK1 was also seen to alter the expression of proteins involved in several cellular processes related to the cell cycle and cellular metabolism. How ADCK1 regulates these processes will be studied in the future. Citation Format: Noel A. Jacquet, Yunfeng Zhao.

Long-term trends in incidence, mortality and burden of liver cancer due to specific etiologies in Hubei Province

Liver cancer, a chronic non-communicable disease, represents a serious public health problem. Long-term trends in the burden of liver cancer disease are heterogeneous across regions. Incidence and mortality of liver cancer, based on the Global Burden of Disease, were collected from the Chinese Centre for Disease Control and Prevention. Age–period–cohort model was utilized to reveal the secular trends and estimate the age, period and cohort effects on primary liver cancer due to specific etiologies. Both the age-standardized incidence and mortality rate of liver cancer in Hubei province were on the rise, although there were discrepancies between gender groups. From age–period–cohort analysis, both incidence and mortality of liver cancer due to Hepatitis B virus were the highest in all age groups. The incidence of all liver cancer groups increased with time period in males, while this upward trend was observed in females only in liver cancer due to alcohol use group. Cohort effects indicated the disease burden of liver cancer decreased with birth cohorts. Local drifts showed that the incidence of liver cancer due to specific etiologies was increasing in the age group of males between 40 and 75 years old. The impact of an aging population will continue in Hubei Province. the disease burden of liver cancer will continue to increase, and personalized prevention policies must be adopted to address these changes.

Cancer burden and risk in the Chinese population aged 55 years and above: A systematic analysis and comparison with the USA and Western Europe.

We analysed the cancer burden among elderly Chinese people over the age of 55 years and compared them to USA and Western Europe to explore the cancer model in China. We retrieved data on 29 cancers with 34 risk factors from the 2019 Global Burden of Disease database to evaluate the cancer burden in Chinese elderly individuals aged 55 years and older. We then used the age-standardised incidence rate (ASIR), age-standardised death rate (ASDR), age-standardised disability-adjusted life year (DALY) rate, and average annual percentage change (AAPC) to compare the characteristics and change trend of cancers among China, USA, and Western Europe. In 2019, the number of incident cases of 29 cancers among people aged 55 years and above in China increased more than 3-fold compared to 1990, while the number of deaths and DALYs approximately doubled. We also found that the cancer population in China was ageing; meanwhile, the cancer burden became significantly higher for men than for women, and the gap between men and women had widened. Cancers with the highest cancer DALYs were lung cancer (13 444 500; 95% uncertainty interval (UI) = 11 307 100, 15 853 700), stomach cancer (7 303 900; 95% UI = 6 094 600, 8 586 500), oesophageal cancer (4 633 500; 95% UI = 3 642 500, 5 601 200), colon and rectum cancer (4 386 500; 95% UI = 3 769 500, 5 067 200), liver cancer (2 915 100, 95% UI = 2 456 300, 3 463 900), and pancreatic cancer (2 028 400; 95% UI = 1 725 000, 2 354 900). Compared with 1990, the DALY rate and incidence rate of stomach cancer, oesophageal cancer, and liver cancer had markedly decreased. The DALY rate and incidence rate of lung, colon, rectum, and pancreatic cancer had increased significantly, as did the incidence rate of breast cancer in women. Smoking and diet were the top two cancer risk factors, and the impact of ambient particulate matter pollution on cancer increased each year. The overall 29 cancers age-standardised DALY rate and ASDR in China, USA, and Western Europe were similar, and all showed downward trend in the past 30 years. Compared with the USA and Western Europe, the age-standardised DALY rate of liver, nasopharyngeal, oesophageal, stomach, and cervical cancers in China was more prominent. The age-standardised DALY rate of lung cancer and colon and rectum cancer decreased annually in Western Europe and the USA, but increased in China. Over the past 30 years, China had made progress in controlling stomach, oesophageal, and liver cancer. However, lung, colon, rectum, pancreatic, and breast cancers had become more prevalent, having risen alongside economic development. The risks of smoking and dietary were major issues that need to be addressed urgently. The cancer situation in China remains serious; future cancer prevention efforts need to balance economic development with people's physical health, identify key groups, improve the health environment of residents and guide them to live a healthy life, and expand the scope of cancer screening.

Gastrointestinal cancer trends in the Hispanic population: A SEER database population study (2000-2019).

725 Background: Cancer continues to be the leading cause of death in the Hispanic population. Gastrointestinal cancer surveillance data in Hispanic individuals has only recently become available in the last 3 decades. Differences in incidence rates among Hispanics and Non-Hispanic Whites (NHWs) need further elucidation. In this study, we analyzed trends in Hispanics and NHW populations across multiple gastrointestinal cancers. Methods: Gastrointestinal cancers (liver, colon and rectum, pancreas, esophagus, gallbladder, stomach, small intestine, anus, anal canal and anorectum) diagnosed between 2000-2019 were identified in the Surveillance, Epidemiology, and End Results Program (SEER) Database. We calculated incidence rates, confidence intervals and incidence rate ratios. Rates are per 100,000 and age adjusted to the 2000 US standard population. Rate ratios are the rounded rates in Hispanic individuals divided by the rounded rates in NHWs. Results: There was a higher incidence of liver, gallbladder, and stomach cancers among Hispanics when compared to NHWs between the years 2000-2019. Liver cancer incidence rate is (11.5 per 100,000) in Hispanics compared with (6.3 per 100, 000) in NHWs with an incidence rate ratio of 1.8. Gallbladder cancer incidence rate is (2.2 per 100,000) in Hispanics compared with (0.9 per 100,000) in NHWs with an incidence rate ratio of 2.4. Stomach cancer is (10.9 per 100,000) in Hispanics compared with (5.7 per 100,000) in NHWs with an incidence rate ratio of 1.9. The lowest incidence rate ratio was seen for anus, anal canal and anorectum cancers in Hispanics compared to NHWs. The incidence rate is (1.2 per 100,000) in Hispanics compared with (2.1 per 100,000) in NHWs with an incidence rate ratio of 0.6. Remaining cancers had incidence rate ratios less than 1.0 and were more likely to occur in NHWs. Conclusions: This study illustrates differing incidence rates of multiple gastrointestinal cancers among Hispanics compared to NHWs. Liver, gallbladder and stomach cancer incidence rates in Hispanics is double that of NHWs. Interestingly, the remaining gastrointestinal cancers had higher incidence rates among NHWs. Further research is warranted to understand the differences in cancer risk within the Hispanic population as well as healthcare access, language barriers and cultural differences that may play a role.[Table: see text]

Relative and collective contribution of liver and bile duct cancer risk factors among minority groups in California.

439 Background: Liver and Bile Duct Cancer is a significant public health concern with higher incidence rates observed among people belonging to racial and ethnic minority groups compared to non-Hispanic White people. This study aims to understand which underlying factors contribute most to this disparity in liver and bile duct cancer. Methods: The California Health Maps database was analyzed from 2015-2019, including 58 counties: consistent with the SEER census and CDC PLACES Project. Variables examined included race, ethnicity, age, health insurance status, foreign-born status, rural residence, obesity prevalence, socioeconomic status, smoking status, and percentage of individuals receiving preventative care. Linear regression analysis was used to determine which factors significantly predict higher prevalence of liver and bile duct cancer. Results: The population consisted of 39,283,494 people, predominantly Hispanic (39%) with 38.7% being non-Hispanic White; 15.5% Asian or Pacific Islander and 6.2% non-Hispanic Black. Hispanic people accounted for 21% of the 868,882 total cancer cases and 33% of the 22,439 cases of liver and bile duct cancers reported. Race and ethnicity were the most substantial predictors of liver and bile duct cancer prevalence; counties with a higher monitory population exhibited higher incidence rates (Hispanic: R=0.39; p=0.003, Black: R=0.39; p=0.004, White: R=-0.55; p<0.0001, Asian: R=0.33; p=0.01). Being foreign-born (R=0.45; p=0.0008), residing in non-rural areas (R= -0.33; p=0.01), and lacking preventative care (women: R= -0.30; p=0.03, men: R= -0.37; p=0.006) were also significantly associated with increased liver and bile duct cancer incidence rates (Table). Conclusions: This study highlights the association of race, ethnicity, and access to healthcare services with higher incidence rates of liver and bile duct cancer among Hispanic and non-Hispanic Black people compared to non-Hispanic White people. Addressing these disparities is crucial for promoting equitable health outcomes in liver and bile duct cancer. [Table: see text]

Progress and application of liver organoids in the study of liver cancer

The incidence rate of liver cancer has been rising in recent years. Traditional cell line culture and human patient-derived tumor xenograft models, which are commonly used tools to simulate the occurrence of human liver cancer, have deepened the understanding of tumor occurrence, development, and drug resistance mechanisms. However, they cannot reflect the accurate state of cancer cells, the tumor microenvironment, or spatial structural characteristics. Recently, more in vitro-produced physiological liver organoids have been applied in the study of liver cancer. Liver organoid models have made breakthroughs in the occurrence and development mechanisms of liver cancer, personalized drug screening and biomarker identification, immunotherapy, and regenerative medicine applications. This paper mainly summarizes the progress and application of liver organoids processed in the study of liver cancer.

Underrepresentation of Hispanics in clinical trials for liver cancer in the United States over the past 20 years.

Accurate representation of racial and ethnic population subgroups in clinical trials is fundamental to ensure universal effectiveness of new therapies as well as to decrease disparities in oncology care. To determine whether Hispanic people are underrepresented in Phase I and II clinical trials for liver cancer in the United States. A database search was performed in clinicaltrials.gov for interventional liver cancer studies based only in the US with reported results from September 1, 2002, to February 1, 2023. A total of 37 trials with 963 total patients met inclusion criteria and were included for further analysis. Proportion of total patients by race/ethnicity was calculated for non-Hispanic white, non-Hispanic black, Asian, Hispanic, and American Indian/Alaska Native subpopulations. The age-adjusted incidence rates of liver and intrahepatic bile duct were acquired from the National Cancer Institute, Surveillance, Epidemiology, and End Results Program. Liver cancer incidence rates (per 100,000 people) were highest in Indians/Alaska Native people (18.8 cases) followed by Hispanic people (15.1 cases), then Asian people (12.5 cases), then non-Hispanic black people (11 cases), and non-Hispanic white people (7.5 cases). From a total of 91 phase I or II clinical trials for liver cancer in the US, 41% reported race/ethnicity enrollment data; among these, 62.8% of patients were non-Hispanic White, 15.9% were non-Hispanic black, 8.8% were Hispanic, 12.7% Asian, and 0.5% American Indian/Alaska Native. Less than half of phase I or II clinical trials for liver cancer in the US in the last 20 years reported race/ethnicity data to clinicaltrials.gov. Compared to the relative incidence rate of liver cancer, non-Hispanic black people and Hispanic people are underrepresented in these clinical trials.

Abstract C041: Transcriptomic analysis of prostate cancer patients living with HIV

Abstract Background: Higher incidence and mortality rates of liver, lung, anal, and head and neck cancers are typically seen in patients living with human immunodeficiency virus (HIV). However, some previous studies have a decreased risk of prostate cancer in HIV+ patients, particularly in men from sexual minorities, with no clear biological or epidemiological explanation. Methods: To identify the specific transcriptomic changes and genetic pathways associated with HIV infection and prostate cancer emergence, we performed bulk RNA-Seq analysis on 18 prostate cancer samples (9 HIV+ and 9 HIV-). We first used kallisto to measure gene-level expression. We then performed principal component analysis (PCA) to determine if HIV status clearly clustered patients based on their gene expression levels. We subsequently used DESeq2 to perform differentially expressed transcriptomic analysis to identify genes that are associated with HIV and prostate cancer phenotypes. Samples were clustered based on expression levels of the top differentially expressed genes across the HIV+ and HIV- phenotypes. Gene set enrichment analysis was performed on the gene signatures from the two phenotypes. Using an existing single cell RNA-Seq prostate cancer dataset, we deconvoluted the 18 samples with CIBERSORT to approximate the cell type composition. Results: PCA highlighted no major separation between samples based on HIV status. We identified 450 significantly upregulated genes in HIV+ patients, including YAP1, MAT2A, KLF4, and ERF. We identified 409 upregulated genes in HIV- patients, including MICA, AQP2, and KRT6C. Upregulated genes found in HIV+ patients were significantly enriched in multiple immune response pathways, which is consistent with previous sequencing studies focused on HIV status. After cell type composition estimation, we found the samples to be similar in their cell type distributions - stromal and tumor cells were the largest populations, while immune cells were not well represented. Conclusions: We identified transcriptomic differences that need future studies that directly interrogate the biological pathways that affect the incidence of prostate cancer in patients living with HIV.

Incidence of Stomach, Liver, and Colorectal Cancers by Geography and Social Vulnerability Among American Indian and Alaska Native Populations, 2010-2019.

Social determinants of health and associated systems, policies, and practices are important drivers of health disparities. American Indian and Alaska Native (AI/AN) populations in the United States have elevated incidence rates of stomach, liver, and colorectal cancers compared with other racial/ethnic groups. In this study, we examined incidence rates of 3 types of gastrointestinal cancer among non-Hispanic AI/AN (NH-AI/AN) and non-Hispanic White (NHW) populations by geographic region and Social Vulnerability Index (SVI) score. Incident cases diagnosed during 2010-2019 were identified from population-based cancer registries linked with the Indian Health Service patient registration databases. Age-adjusted incidence rates (per 100,000 population) for stomach, liver, and colorectal cancers were compared within NH-AI/AN populations and between the NH-AI/AN and NHW populations by SVI score. Rates were higher among NH-AI/AN populations in moderate- and high-SVI-score counties in Alaska, the Southern Plains, and the East than in low-SVI counties. Incidence rates among NH-AI/AN populations were elevated when compared with NHW populations by SVI category. Results indicated that higher social vulnerability may drive elevated cancer incidence among NH-AI/AN populations. Additionally, disparities between NH-AI/AN and NHW populations persist even when accounting for SVI. Exploring social vulnerability can aid in designing more effective interventions to address root causes of cancer disparities among AI/AN populations.

Trends and future projections of liver cancer incidence in Hong Kong: a population-based study

BackgroundLiver cancer remains a significant burden in Hong Kong. We sought to examine trends in liver cancer incidence using 30 years of cancer registry data in Hong Kong. Additionally, we aimed to assess the impact of age, period and birth cohort on liver cancer incidence, provided projections for liver cancer incidence until 2030, and examined the drivers of liver cancer incidence.MethodsData on liver cancer incidence were collected from the Hong Kong Cancer Registry (HKCaR). We assessed age, period, and birth cohort effects using age-period-cohort (APC) models. We employed Bayesian APC analysis with integrated nested Laplace approximations to project the future burden of liver cancer in Hong Kong. Furthermore, we attributed the changes in new liver cancer cases to population growth, population ageing, and epidemiological changes.ResultsThe study included a total of 51,333 individuals, of whom 39,287 (76.53%) were male. From 1991 to 2020, the age-standardized liver cancer incidence rate in Hong Kong continued declining, while the number of new cases increased significantly, especially among males. The net drift, representing the overall annual percentage change of the age-adjusted rate, was − 3.06% (95% confidence interval [CI]: -3.31% to -2.80%) for males and − 3.85% (95% CI: -4.61% to -3.09%) for females. Local drift, which estimates the annual percentage change over time specific to age group, decreased in all age groups for both sexes, with a more pronounced decrease in younger age groups. The period and cohort risk of developing liver cancer also showed decreasing trends for both sexes. The study projected a decline in liver cancer cases for males but an increase for females in Hong Kong, with an estimated 1,083 cases in males and 710 cases in females by 2030. Demographic decomposition analysis revealed that while population growth and ageing were the main drivers of increased liver cancer cases, epidemiologic shifts mostly offset these factors.ConclusionThe period and cohort risk of developing liver cancer in Hong Kong declined due to epidemiological changes. Although the age-standardized incidence rates of liver cancer have also declined, demographic and epidemiological factors have led to lower case expectations in males but a likely increase in females. Further research and epidemiological assessment of the disease are needed.

Hispanic Individuals are Underrepresented in Phase III Clinical Trials for Advanced Liver Cancer in the United States.

Hispanic individuals comprise the second-largest subpopulation after non-Hispanic White (NHW) individuals in the United States (US). We compared the relative contribution of Hispanic individuals to the ten most common causes of cancer-related deaths and studied enrollment of Hispanic patients in multinational phase III advanced liver cancer trials with the aim to investigate whether racial subpopulations are adequately represented in liver cancer trials. Relative cancer incidence rates in Hispanic individuals, NHW individuals, non-Hispanic black (NHB) individuals, and Asian individuals were obtained from both the National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results Program and the Center for Disease Control and Prevention (CDC), United States Cancer Statistics (USCS) database. Searching PubMed, Embase, and Web of Science, we identified phase III clinical trials studying advanced liver cancer in the last ten years and collected enrollment for each race and ethnicity. Incidence rates of liver cancer and enrollment rates in phase III trials were compared by race and ethnicity. The cancer type with the relatively highest contribution of Hispanic individuals was liver cancer. From 2015 to 2019, 15.1% of liver cancer cases occurred in Hispanic individuals compared to 12.5% in Asian individuals, 11% in NHB individuals, and 7.5% in NHW individuals. In the last ten years, Hispanic individuals made up 1.6% of patients and NHB individuals 1.3% of patients included in phase III multinational liver cancer trials, compared to 31% NHW individuals and 47% Asian individuals. Hispanic individuals are disproportionately underrepresented in multinational phase III clinical trials for liver cancer despite having the highest relative incidence rates among the four major racial or ethnic groups in the US.

Gastrointestinal cancer trends in the Hispanic population: A SEER database population study (2000-2019).

Conclusions: This study illustrates differing incidence rates of multiple gastrointestinal cancers among Hispanics compared to NHWs. Liver, gallbladder and stomach cancer incidence rates in Hispanics is double that of NHWs. Interestingly, the remaining gastrointestinal cancers had higher incidence rates among NHWs. Further research is warranted to understand the differences in cancer risk within the Hispanic population as well as healthcare access, language barriers and cultural differences that may play a role.

Effective Platform for Enhancing the Bioavailability and Anti-Cancer Efficacy of Norcantharidin: Nanoemulsion Hybrid Lipid Carriers

Novel antitumor drugs and nano-delivery systems for treating liver cancer are becoming a research hotspot, given that the incidence and mortality rates of liver cancer are high. Herein, nanoemulsion hybrid lipid carriers containing norcantharidin (Nor) (NNHLCs) were first prepared by loading water-in-oil nanoemulsions into hybrid solid lipids using nanoemulsion-thin film ultrasonic dispersion method. The in vitro and in vivo kinetic features were determined by in situ unidirectional perfusion and plasma concentration-time curve method, respectively. The activity of NNHLCs against liver cancer HepG2 cells was determined by evaluating in vitro cytotoxicity, clone formation, apoptosis, and cell cycle experiments. Fourier transform infrared (FT-IR) spectroscopy, differential scanning calorimetry (DSC), and X-ray diffraction (XRD) results indicated that Nor exists in NNHLCs in an amorphous state with good encapsulation in the lipid matrix. The absorptive constants and permeabilities of NNHLCs were significantly increased compared with Nor. The relative bioavailability of NNHLCs to Nor was 207.68%. NNHLCs could inhibit the viability and proliferation of HepG2 cells and promote apoptosis. Thus, nanoemulsion hybrid lipid carriers may provide a new option for the efficient delivery of chemotherapeutic drugs.

Apoptotic Mechanisms of Quercetin in Liver Cancer: Recent Trends and Advancements

Due to rising incidence rates of liver cancer and worries about the toxicity of current chemotherapeutic medicines, the hunt for further alternative methods to treat this malignancy has escalated. Compared to chemotherapy, quercetin, a flavonoid, is relatively less harmful to normal cells and is regarded as an excellent free-radical scavenger. Apoptotic cell death of cancer cells caused by quercetin has been demonstrated by many prior studies. It is present in many fruits, vegetables, and herbs. Quercetin targets apoptosis, by upregulating Bax, caspase-3, and p21 while downregulating Akt, PLK-1, cyclin-B1, cyclin-A, CDC-2, CDK-2, and Bcl-2. Additionally, it has been reported to increase STAT3 protein degradation in liver cancer cells while decreasing STAT3 activation. Quercetin has a potential future in chemoprevention, based on substantial research on its anticancer effects. The current review discusses quercetin's mechanisms of action, nanodelivery strategies, and other potential cellular effects in liver cancer.

Time-trends in liver cancer incidence and mortality rates in the U.S. from 1975 to 2017: a study based on the Surveillance, Epidemiology, and End Results database.

A previous study has examined the overall cancer statistics. However, more detailed statistics regarding liver cancer have not been provided. We evaluated the incidence and mortality trends of liver and intrahepatic bile duct cancer in the United States from 1975 to 2017 based on the data in the Surveillance, Epidemiology, and End Results (SEER) database. Age, gender, race, metastasis, tumor site, and tumor grade of patients were extracted from the SEER database. Codes C22.0 and C22.1 of the International Classification of Disease for Oncology were applied to identify patients with hepatocellular carcinoma (HCC) and/or intrahepatic cholangiocarcinoma (ICC). Age-specified incidence, age-standardized incidence and mortality, 5-year relative survival, race-specific accumulative incidence and mortality, and geographic-specific accumulative mortality were calculated in different groups. Changes in trends of liver cancer incidence and mortality were assessed using Joinpoint regression. The overall incidence increased significantly from 2.641/100,000 person-years in 1975 to 8.657/100,000 person-years in 2017 [average annual percent change (AAPC) =3.42, 95% confidence interval (CI): 3.28-3.62, P<0.001]. The steepest incidence rate increase was observed in the 60-69-year-old age group (AAPC =4.40, 95% CI: 4.10-4.70, P<0.001). Males exhibited a more rapid increase in cancer incidence, from 3.928/100,000 to 13.128/100,000 person-years (AAPC =3.41, 95% CI: 3.21-3.61, P<0.001), than females [from 1.642/100,000 to 4.783/100,000 person-years (AAPC =3.03, 95% CI: 2.91-3.21, P=0.001)]. The overall mortality rate increased from 2.808/100,000 person-years in 1975 to 6.648/100,000 person-years in 2017 (AAPC =2.41, 95% CI: 2.29-2.51, P<0.001). The highest mortality rate was observed in Hawaii (6.996/100,000 person-years). The incidence and mortality rates of HCC and ICC increased from 1975 to 2017, especially in males, non-Hispanic Blacks and older individuals. Comprehensive policy and control measures should be implemented to reduce the burden of disease, particularly through health monitoring and intervention for high-risk groups.

Decrease in liver cancer incidence rates in Bamako, Mali over 28 years of population-based cancer registration (1987-2015).

BACKGROUNDPrimary liver cancer is common in West Africa due to endemic risk factors. However, epidemiological studies of the global burden and trends of liver cancer are limited. We report changes in trends of the incidence of liver cancer over a period of 28 years using the population-based cancer registry of Bamako, Mali.AIMTo assess the trends and patterns of liver cancer by gender and age groups by analyzing the cancer registration data accumulated over 28 years (1987-2015) of activity of the population-based registry of the Bamako district.METHODSData obtained since the inception of the registry in 1987 through 2015 were stratified into three periods (1987-1996, 1997-2006, and 2007-2015). Age-standardized rates were estimated by direct standardization using the world population. Incidence rate ratios and the corresponding 95% confidence intervals (CI) were estimated using the early period as the reference (1987-1996). Joinpoint regression models were used to assess the annual percentage change and highlight trends over the entire period (from 1987 to 2015).RESULTSAmong males, the age-standardized incidence rates significantly decreased from 19.41 (1987-1996) to 13.12 (1997-2006) to 8.15 (2007-2015) per 105 person-years. The incidence rate ratio over 28 years was 0.42 (95%CI: 0.34-0.50), and the annual percentage change was -4.59 [95%CI: (-6.4)-(-2.7)]. Among females, rates dropped continuously from 7.02 (1987-1996) to 2.57 (2007-2015) per 105 person-years, with an incidence rate ratio of 0.37 (95%CI: 0.28-0.45) and an annual percentage change of -5.63 [95%CI: (-8.9)-(-2.3)].CONCLUSIONThe population-based registration showed that the incidence of primary liver cancer has steadily decreased in the Bamako district over 28 years. This trend does not appear to result from biases or changes in registration practices. This is the first report of such a decrease in an area of high incidence of liver cancer in Africa. This decrease may be explained by the changes and diversity of diet that could reduce exposure to aflatoxins through dietary contamination in this population.
