Hepatocellular carcinoma. A clinical and pathologic analysis of 57 hepatectomy cases
Insights
Hepatocellular carcinoma (HCC) in normal livers grows larger and differs in pattern compared to HCC in cirrhotic livers. Tumor size and histologic features significantly impact patient survival.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Hepatocellular carcinoma (HCC) is a significant global health concern.
- Understanding the clinicopathologic features of HCC is crucial for effective treatment strategies.
- The relationship between liver conditions like cirrhosis and HCC development requires further investigation.
Purpose of the Study:
- To conduct a clinicopathologic analysis of 57 hepatectomy cases of hepatocellular carcinoma (HCC).
- To investigate the influence of liver status (normal, precirrhosis, cirrhosis) on HCC growth patterns and patient outcomes.
- To explore the association between Hepatitis B Virus (HBV) and HCC pathogenesis.
Main Methods:
- Clinicopathologic analysis of 57 hepatectomy cases.
- Comparison of HCC characteristics (size, growth pattern) in normal versus cirrhotic livers.
- Evaluation of factors influencing patient survival post-hepatectomy.
- Assessment of serum Hepatitis B Virus (HBV) surface antigen positivity rates.
Main Results:
- Complication rates were 33.3% for both precirrhosis and cirrhosis.
- HCC in normal livers was larger (average 9.2 cm) and showed microtrabecular growth (83%) compared to HCC in cirrhotic livers (average 4.7 cm, macrotrabecular 67%).
- Survival was significantly influenced by smaller tumor size, lower histologic grade, bile production, and absence of satellite tumors/giant cells. HBV surface antigen positivity averaged 47.2%.
Conclusions:
- Liver status significantly impacts HCC growth patterns and tumor size.
- Tumor characteristics and histologic features are critical prognostic indicators for HCC patients.
- The study discusses the potential role of HBV in the pathogenesis of HCC.
Abstract:
The following is a clinicopathologic analysis of 57 hepatectomy cases of hepatocellular carcinoma (HCC). The rates of complication from precirrhosis and cirrhosis were 33.3% each. Cirrhosis seemed to have preceded HCC in 13 cases (39.4%) and both diseases appeared to have developed simultaneously in 18 cases (54.5%). Growth patterns of HCC were related to histologic features of livers bearing HCC: HCCs occurring in normal livers were significantly larger in average tumor size than those occurring in cirrhotic livers (9.2 as compared to 4.7 cm) and tended to exhibit a microtrabecular growth pattern (83% of the cases), while HCCs occurring in cirrhotic livers were most commonly macrotrabecular (67%). The factors most significantly influencing survival were the smallness of removed liver and tumor, histologic grades, the presence of bile production, and the absence of satellite tumors and giant cells. The positivity rates of serum hepatitis B virus (HBV) surface antigen averaged 47.2% and the relation of HCC to the role of HBV in the pathogenesis of HCC was discussed.
