Abstract

Background: Sarcomatous hepatocellular carcinoma (HCC) has a worse prognosis than ordinary HCC. The relationship between the malignant potential of sarcomatous HCC and cell proliferation or cell adhesion is unknown. This study was undertaken to clarify this relationship. Methods: In 21 cases of sarcomatous HCC, including 16 surgically resected and five autopsy cases, immunohistochemistry was used to compare the sarcomatous component (s-comp) and the ordinary component (o-comp) within each sarcomatous HCC. Results: We found 15 epithelial-cadherin (E-cadherin)-positive cases in o-comp (79%) and nine positive cases in s-comp (43%). The difference between sarcomatous HCC and ordinary HCC in E-cadherin-positive tumor prevalence was significant (P<0.05). The Ki-67 (MIB1) labeling index ratio was 127±40 in s-comp and 80±33 in o-comp, and there was a greater tendency to have an ability to multiply in s-comp than in o-comp (P=0.096). Conclusion: This study indicated that the loss of E-cadherin related to a morphological alteration in sarcomatous HCC; however, no relationship in respect to the malignant potential was found.
