Differential diagnosis of @entity157 and XXXX and therapeutic strategy.

BACKGROUND/AIMS: To investigate imaging characteristics and surgical results of @entity1412 and @entity5 . METHODOLOGY: A retrospective study set in the First Department of Surgery, University of Tokushima, Japan. From 1994 to 1997, 33 @entity1 with 55 @entity157 (< or = 3 cm) and 10 @entity75 (3 @entity1412 , 5 atypical @entity1412 , 2 atypical @entity1412 with @entity5 ) were enrolled for this study. The detectability of these lesions on imaging was evaluated. Cumulative survival and disease-free survival rates were also calculated. RESULTS: Twenty-eight @entity1 were incidentally diagnosed on ultrasonography during follow-up study for @entity102 . In the conventional studies, detection rates of ultrasonography, computed tomography and angiography for @entity157 and @entity75 were 76% 80%, 33% 10% and 36% 20%, respectively. Magnetic resonance imaging, intraoperative ultrasonography, helical computed tomography and portal angiographic computed tomography showed better results of 67% 20%, 100% 90%, 70% 50% and 74% 56%, respectively. On differential diagnosis, the ratio of echo level in @entity157 was significantly higher than that in @entity75 . The 3-year and 5-year survival rates for all @entity1 were 61% and 41%, while disease-free survival rates at the corresponding times were 15% and 7%, respectively. A total of 25 @entity1 (76%) developed intrahepatic recurrence during a mean follow-up of 33.8 months, although there was no recurrent lesion in 4 @entity1412 @entity1 treated with microwave coagulation therapy and @entity1068 injection intraoperatively. CONCLUSIONS: For @entity5 larger than 1 cm in diameter, the detection rates with various diagnostic modalities were rather high. However, the differential diagnosis of @entity157 could be based on pathologic studies only. Early detection of small hepatic lesions and treatment by methods such as resection or @entity1068 injection are of critical importance in improving long-term survival.
