BACKGROUND/AIMS: |
TextSentencer_T3 |
110-327 |
Sentence |
denotes |
The multistep development of overt hepatocellular carcinoma from very well-differentiated early hepatocellular carcinoma, and of early hepatocellular carcinoma from adenomatous hyperplasia has been strongly suggested. |
TextSentencer_T4 |
328-486 |
Sentence |
denotes |
The clinicopathologic and immunohistochemical characteristics of solitary minute hepatocellular carcinomas smaller than 1 cm in size have yet to be clarified. |

METHODOLOGY: |
TextSentencer_T6 |
500-583 |
Sentence |
denotes |
Fourteen minute hepatocellular carcinomas were divided into 2 groups consisting of: |
TextSentencer_T7 |
584-849 |
Sentence |
denotes |
1) hepatocellular carcinoma of hepatitis B surface antigen positive patients (B-HCC) (n = 5), and 2) hepatocellular carcinoma of hepatitis C virus antibody positive patients (C-HCC) (n = 9), then they were all analyzed histopathologically and clinicopathologically. |

850-939 |
Sentence |
denotes |
Immunohistochemical studies were also performed using the antibodies against p53 protein. |
TextSentencer_T9 |

Sentence |
denotes |
RESULTS: |
TextSentencer_T10 |
949-1062 |
Sentence |
denotes |
Six of the 14 minute hepatocellular carcinoma were demonstrated to be moderately or poorly differentiated tumors. |
TextSentencer_T11 |
1063-1187 |
Sentence |
denotes |
Among the 8 well-differentiated minute hepatocellular carcinomas, 2 tumors already contained less differentiated components. |
TextSentencer_T12 |
1188-1249 |
Sentence |
denotes |
B-HCC tended to be less differentiated than C-HCC (P < 0.05). |
TextSentencer_T13 |
1250-1312 |
Sentence |
denotes |
Adenomatous hyperplasia was detected in only 2 cases of C-HCC. |
TextSentencer_T14 |
1313-1417 |
Sentence |
denotes |
Small cell liver dysplasia was detected significantly more frequently in C-HCC than in B-HCC (P < 0.05). |
TextSentencer_T15 |
1418-1495 |
Sentence |
denotes |
The prognosis of the 14 minute hepatocellular carcinomas varied considerably. |
TextSentencer_T16 |
1496-1569 |
Sentence |
denotes |
Immunohistochemically, some tumor cells were positive for p53 in 3 cases. |
TextSentencer_T17 |
1570-1582 |
Sentence |
denotes |
CONCLUSIONS: |
TextSentencer_T18 |
1583-2053 |
Sentence |
denotes |
Our study suggests that 1) the multistep carcinogenesis through adenomatous hyperplasia may not be so frequent, 2) De novo carcinogenesis from not only well-differentiated hepatocellular carcinoma, but also from less differentiated hepatocellular carcinoma, especially B-HCC, may be present, 3) the carcinogenesis in the B-HCC cases may behave differently from that in C-HCC cases, and 4) minute hepatocellular carcinomas demonstrate varying prognoses after hepatectomy. |
