Hepatocellular carcinoma (HCC) is on the rise worldwide and in the US, and despite emerging treatment modalities, its overall prognosis remains poor; therefore, there is a need for preventing its development globally. The major factors contributing to HCC development, namely, infections with hepatitis B and hepatitis C viruses, alcoholic cirrhosis, aflatoxin-contaminated food, non-alcoholic fatty liver disease, metabolic syndrome, and smoking are modifiable; and prevention intervention can start in childhood.

Vaccination for hepatitis B, screening for and treatment of hepatitis C and intravenous drug users, education to avoid fatty liver, alcoholism, and substance use were shown to be effective ways to curb HCC incidence. A focus on reducing early childhood adversity and training young children to make healthy decisions has been strongly recommended as a prevention strategy to reduce most of HCC risk factors.

Hepatocellular carcinoma (HCC) is on the rise worldwide1 and in the US2,3. It disproportionally affects areas endemic for hepatitis C (HCV) and hepatitis B (HBV) viruses, such as Egypt and southeast Asia, respectively4,5. Therapeutic options depend on the cancer stage6,7, which is commonly advanced at diagnosis; and despite emerging treatment modalities, the overall prognosis for HCC remains poor3 (5-years survival ~18%), thus it needs to be prevented globally.

Risk factors contributing to the development of HCC are infections with HBV and HCV8-11, alcoholic cirrhosis,12 aflatoxin-contaminated food13, non-alcoholic fatty liver disease (NAFLD)2,14, metabolic syndrome15,16, smoking17, and possibly genetic components18,19. Except for the genetic components, these risk factors are modifiable through treatment and prevention interventions that should be initiated in childhood.

For over 15 years, we successfully conducted epidemiological research studies in Egypt20-27, where the burden of HCV infection is the highest worldwide and HCC incidence is on the rise1,4. We focused on investigating HCC risk factors and prevention, implementing the Egypt Smoking Prevention Research Initiative (ESPRI), and Project DARE (Drug Abuse Research in Egypt). Therefore, we are well-positioned to address this challenging disease risk factors and provide unique perspectives on how to reduce them.

Chronic infection with HBV is a well-established risk for HCC development. In HBV infected individuals, HCC risk increased with the increase in viral load8; and HCC incidence rate following HBV infection increased from 0.2 per 100 person-years in inactive carriers, to 0.6 in those with chronic HBV infection, to 3.7 in those with compensated cirrhosis28. Most of HCC cases in children and young adults are associated with HBV infection9,29.

HBV spread through contact with infected body fluids; thus the risk of infection is high among healthcare workers, intravenous drug users (IDU), and newborns of infected mothers. In addition, intra-familial transmission of HVB was reported among family members of chronic HBV carriers30.

Since the development of an effective HBV vaccine and its widespread use, HCC incidence has substantially declined, particularly in HBV endemic areas31. Although newborn HBV vaccination has achieved tremendous progress toward elimination of perinatal and early childhood viral transmission32, HBV infection and HCC risk remain high in low-income countries with endemic HBV and where vertical transmission from mother to child is the main mode of infection; screening of all pregnant women and passive immunization with human hepatitis B immunoglobulin are not affordable33. Further, there are knowledge gaps among physicians and midwives about the use of HBV vaccine and immunoglobulin therapy to prevent HBV transmission from mother to newborn34. Interventions to fill these knowledge gaps among health care providers could, therefore, have a positive impact on lowering HBV transmission rates to children.

HCV, like HBV, is an established risk factor for HCC. It induces hepatic inflammation and ultimately cirrhosis and promotes hepatic cell transformation that leads to HCC10. Meta-analysis of 21 studies showed that individuals infected with HCV 1b genotype are at higher risk of developing HCC as compared to those infected with other HCV genotypes11. Parenteral anti-schistosomal therapy campaigns conducted from the 1950s through the 1980s, and using not well-sterilized needles, and the subsequent intra-familial HCV transmission from parent-to-offspring and sibling-to-sibling in rural communities35 resulted in Egypt having the largest burden of HCV infection in the world4, and a substantial rise in HCC incidence.

Unlike HBV, there is no HCV vaccine, and the burden of HCV continues to increase, because of the opiates epidemic among intra-venous drug users (IDU) in the U.S. and elsewhere. A meta-analysis of studies of chronic hepatitis C patients showed a substantial reduction in HCC risk when anti-viral therapy achieved sustained viral response36. A Cochrane Database systemic review37 of interventions studies among IDUs found combination strategies, which included opiate substitution therapy and coverage of needle syringe program, substantially reduce the incidence of HCV.

Screening individuals at risk for HCV, and using the new direct-acting antiviral therapies have the potential to reduce HCV transmission and incidence, and its related morbidity. To screen for HCV, treat the active form, and/or refer patients for counseling, education of healthcare providers is needed.

Considering that HCV transmission via IDU behaviors is a major factor sustaining the current HCV reservoir in the population and experimenting with drugs in childhood is associated with substance abuse and addiction later in life, prevention intervention should start among youth. Adverse childhood experiences were reported to impact subsequent behavior and substance abuse in adolescents and young adults38,39. and to be one of the most common contributing factors to substance use among Egyptian youth27. Training youth to acquire skills representing the ‘executive function’40 and thus allowing them to deal with adversity and make healthy decisions41,42 was reported to be effective.

Dietary aflatoxin, produced by Aspergillus molds that infect stored grains and other foods, is classified by the International Agency of Research on Cancer (IARC) as a class 1 human carcinogen13. In Egypt where HCC is highly prevalent, studies have shown the presence of AFB1-albumin adducts in human blood43,44, and that both local and imported food samples were positive for aflatoxin22.

A study from China reported HCC risk in patients with chronic HBV and aflatoxin exposure to be 60 times the risk in non-exposed45. Epidemiological studies, conducted in China, Taiwan and sub-Saharan Africa and addressing aflatoxin exposure and HCC risk, estimated the population attributable risk to be 17% overall, and higher among HBV positive (21%) than in HBV negative (8.8%) populations; aflatoxin appeared to interact multiplicatively with HBV to induce HCC46.

Aspergillus mold contamination and accumulation of aflatoxin in foods can be prevented through safe food storage and preparation practices. Awareness campaigns among populations exposed to aflatoxin were reported to reduce fungal contamination47. Studies in West Africa showed that aflatoxin metabolites were lowered after a low-cost, sustainable village intervention that emphasized proper storage of peanuts and hand picking and disposing of moldy nuts prior to cooking48.

Although aflatoxin concentration in agricultural food and feed products is regulated worldwide, production of contaminated maize in Europe was, not only predicted because of climate change, but it was also observed in some countries49. Hence, regulations governing safe grain production and use must be reinforced, particularly in countries where other HCC risk factors are prevalent among children.

In the US, from 1999 to 2016, annual cirrhosis-related mortality increased by 65% and that from HCC doubled50; driven entirely by alcohol, the highest cirrhosis-related mortality occurred in people aged 25-34 years50.

Alcohol use in chronic HCV infection doubles the risk for HCC as compared with the risk in HCV alone.12 A study in Argentina reported alcoholic cirrhosis and HCV as the main contributing factors to HCC51. The odds of developing cirrhosis among chronic HCV patients were 2.3 higher in heavy alcohol drinkers as compared to nondrinkers or low quantity drinkers52. In a prospective study of 2215 patients with chronic viral hepatitis, in those with cirrhosis HCC risk was increased three times by heavy alcohol intake53. Therefore, prevention of alcohol abuse can significantly limit hepatic injury.

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) developed a user-friendly, matrix-based tool (college alcohol intervention matrix or CollegeAIM) as a guide for school officials to inform decisions about alcohol intervention strategies and keep students safe54. According to a national survey, almost 60% of college students ages 18–22 drank alcohol in the past month55, and 2 out of 3 of them engaged in binge drinking during that same timeframe.

Preventing alcohol use initiation, like other addictive substance use, can greatly benefit from training youth to deal with adversity and make healthy decisions (see hepatitis C paragraph above)41,42. In addition, focusing on reducing early childhood adversity has been strongly recommended39,56, particularly for disadvantaged children and families. To date, children’s healthcare providers have rarely addressed the social and emotional determinants of health and the context in which children live, despite the potential impacts of these factors on adult health.

NAFLD has been reported as a cause for HCC2,14. Considering the increase in the prevalence of NAFLD and nonalcoholic steatohepatitis, it is likely that these conditions will drive HCC incidence even higher than present levels if the obesity epidemic, the major underlying cause, continues unabated in many areas of the world57.

NAFLD, which is associated with metabolic syndrome, was more prevalent among HCC cases (37.1%) compared to controls (17.1%) and significantly associated with an elevated risk of HCC in a study using SEER-Medicare database15. A study of the Swedish cohort AMORIS showed that elevated individual components of metabolic syndrome, i.e., triglycerides and elevated glucose, and diabetes were associated with an increased risk of developing HCC even without cirrhosis16. Type 2 diabetes was found to be independently associated with increased HCC risk in the Nurses' Health Study and the Health Professionals Follow-up Study; both of which are prospective cohorts of U.S. women (n=120,826) and men (n=50,284), respectively58. The risk increased with diabetes duration and with metabolic comorbidities, hence the suggestion that insulin resistance plays a role in HCC pathogenesis58.

Inherited factors have been associated with HCC risk in NAFLD.14 Some authors postulated that NAFLD results from the interaction between genetic predisposition and environmental, behavioral, and health factors, including diet, diabetes, and obesity18. Adiposity and BMI may act as risk modifiers of the putative genetic factor underlying fat accumulation in the liver19.

Considering that non-alcoholic steatohepatitis, the second leading cause of liver disease in adults awaiting liver transplantation in the US59, is a predisposing HCC risk factor, prevention intervention to reduce such risk is paramount. Improved diet, largely driven by increased consumption of fruits, vegetables, nuts, legumes, and decreased consumption of red meat and trans-fat, was associated with reduced risk of fatty liver and thus NAFLD60. The American Association for the Study of Liver Diseases recommends lifestyle modification, primarily a weight loss diet, for the treatment of NAFLD61. Interestingly, school-based obesity prevention intervention that included diet, education, and physical activity, can improve health among low-income schoolchildren62. After-school programs that integrates daily physical activity and health education among ethnic and socioeconomically diverse communities can be a significant resource for combating childhood obesity63 and ultimately preventing diabetes, metabolic syndrome, and HCC.

A systematic review of 81 cohort and case-control studies showed that cigarette smoking increases HCC incidence and mortality17. Therefore, smoking prevention strategies, particularly those intended to prevent children from taking up the habit, have the potential to further control HCC.

A review of 15 studies showed a possible association between specific pesticides and HCC risk64. VoPham et al. used GIS-based exposure estimates to study pesticide exposure and HCC in California and they found positive association with the organochlorine types64. Agricultural exposures to insecticides and herbicides are common in Egypt, and they were reported to increase the risk of HCC21, although not to the same level of magnitude as HBV and HCV. A study of farmers in Egypt, of whom 61% did not receive school education, revealed that the more educated the individuals were the more knowledge they have about pesticides and their safe use65. Another educational intervention to improve farming families’ knowledge and practices in protecting their children from exposure to pesticides showed that one month after the intervention, knowledge and practice performance were better, not only among younger and more educated participants, but also among those assigned to the videotape compared to those assigned to the lecture66. Therefore, basic education leading to the ability to read and understand the safe handling of pesticides is necessary for avoiding contamination and exposure, not only among farmers, but also among their children.

As shown in Table 1, prevention interventions, through vaccination against infectious hepatitis and early avoidance of established risk factors, such as fatty liver, alcoholism, and substance use, would be highly effective ways to curb HCC incidence. A focus on reducing early childhood adversity and training young children to make healthy decisions to avoid alcoholism, smoking, and intra-venous drugs, and thus potential HCV infection, has been strongly recommended; this is another prevention strategy in childhood to help reduce HCC incidence later in life.
