Insights
Hepatocellular carcinoma (HCC) in West Africa presents at advanced stages, regardless of cause like hepatitis B or C. Few differences were found between etiological agents, highlighting the need for early detection strategies.
Area of Science:
- Hepatology
- Oncology
- Infectious Diseases
Background:
- Hepatocellular carcinoma (HCC) is a prevalent malignancy globally, with a significant burden in West Africa.
- Limited data exist on etiological differences in HCC presentation within this region.
Purpose of the Study:
- To characterize the demographical, clinical, and pathological features of HCC based on etiological factors.
- To investigate associations between hepatitis B virus (HBV), hepatitis C virus (HCV), and aflatoxin exposure in HCC patients.
Main Methods:
- Analysis of 193 HCC cases diagnosed in The Gambia between 1997 and 2001.
- Comparison of patient characteristics by etiology using appropriate statistical tests (chi-squared, t-tests, Wilcoxon rank-sum).
Main Results:
- Prevalence of HBV surface antigen, HCV antibody, and aflatoxin-associated TP53 mutations were 60%, 20%, and 38%, respectively.
- Typical patient: 49-year-old male with HBV, presenting with hepatomegaly, abdominal pain, and weight loss.
- Most patients had multifocal lesions, background cirrhosis, advanced stage HCC (84%), median largest tumor 10.3 cm, and median AFP 500 ng/ml.
Conclusions:
- HCC in West African populations presents at advanced stages, irrespective of the etiological agent.
- Minimal clinical or pathological distinctions were observed among different etiologies.
- Further research is required to understand hepatocarcinogenesis mechanisms and identify high-risk groups for screening.
Background:
Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide, with a high burden in West Africa. Data evaluating aetiological differences in HCC presentation from this region are limited.
Aims:
The aim of this study was to describe the demographical, clinical and pathological characteristics of HCC by aetiology (hepatitis B or C infection, aflatoxin associated).
Methods:
One hundred and ninty-three cases of HCC diagnosed between 1997 and 2001 in The Gambia were analysed. Characteristics were compared by aetiology using χ(2)-tests, student t-test and Wilcoxon's rank sum tests as appropriate.
Results:
The prevalence of hepatitis B surface antigen, hepatitis C antibody and aflatoxin-associated 249(ser) TP53 mutations among HCC patients was 60, 20 and 38% respectively. The typical HCC patient was a 49-year-old male positive for hepatitis B surface antigen presenting with hepatomegaly (93%), abdominal pain (94%) and weight loss (95%) 8 weeks after symptom onset. Most patients had multifocal lesions with background cirrhosis. The median largest tumour was 10.3 cm and the median α-fetoprotein level was 500 ng/ml. Eighty-four per cent of patients had advanced HCC (patients not meeting the Milan criteria) at presentation.
Conclusions:
Irrespective of aetiological agent, HCC among West Africans presents at very advanced stages. Few clinical or pathological differences exist by aetiology. More studies are needed to understand the mechanisms of hepatocarcinogenesis among these patients as well as identify high-risk populations in which early detection through screening will be beneficial.
