Background: Dysregulation of cell proliferation is one of the most important features of human cancers including hepatocellular carcinoma (HCC). However, the molecular basis underlying the proliferation of HCC has not been fully clarified. Because a previous study reported that overexpression of extracellular signal-regulated protein kinase (ERK), which transduces extracellular growth stimuli to the nuclei, was frequently observed in several human cancers, this study was performed to analyze the expression of ERK in human HCC and its correlation with HCC proliferation.

A 52-year-old male was diagnosed with type 3 gastric cancer of angulus (poorly differentiated adenocarcinoma) with left neck, Virchow, mediastinal and abdominal lymph nodes metastases. The patient was treated with 5 courses of M-FLP (MTX + 5-FU + LV + CDDP), and the effect of this therapy was PR, but the tumor was chemoresistant to the sixth course of this therapy.

Because E-cadherin-mediated epithelial cell-to-cell adhesion is thought to suppress cancer cell invasion, the present study was performed to analyze the correlation between E-cadherin expression and the gross classification of HCC.
Methods: Thirty-six resected solitary HCC <6 cm in diameter were each classified as single nodular type (type 1), single nodular with extranodular growth type (type 2) or contiguous multinodular type (type 3), and the clinicopathological and prognostic differences between type 1 HCC and the other types were analyzed.
