Multicenter prospective analysis of newly diagnosed hepatocellular carcinoma with respect to the percentage of Lens culinaris agglutinin-reactive ,-fetoprotein,

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 12 2001
Hiroko Oka
Abstract Background and Aim: The Lens culinaris agglutinin-reactive fraction of ,-fetoprotein (AFP-L3) has been reported to be a highly useful marker for hepatocellular carcinoma (HCC) compared with a conventional serum AFP concentration, which allows earlier detection of HCC compared with using other imaging modalities and predicting prognosis after therapy. A collaborative prospective study involving nine Japanese hospitals was conducted to analyze the relationships between the tumor characteristics of a HCC patient and the percentage of AFP-L3/AFP total at the initial detection. Methods: Between 1 October 1996 and 30 September 1997, a total of 388 patients with newly diagnosed HCC were registered. Results: The cut-off level of the percentage of AFP-L3 was altered from 15 to 10%. The AFP-L3-positive HCC patients demonstrated the characteristics of having an advanced tumor, such as the number of tumors, maximum diameter, tumor spread, portal vein invasion, tumor stage, and tumor classification. With the conventional cut-off level of 15% of the percentage of AFP-L3, the malignant characteristics were more definite than that of 10%. However, no significant differences of serum AFP concentration were observed for malignant characteristics such as maximum diameter and histopathological grading. Conclusion: Serum AFP concentration does not reveal a malignancy of HCC, however, the AFP-L3-positive HCC has biologically malignant characteristics, especially portal vein invasion and lower tumor classification, and is an advanced tumor regardless of small tumor size and lower serum AFP concentration. As AFP-L3 shows the tumor characteristics, its presence should be an important factor in the determination of therapy and prognosis of patients. [source]

Adjuvant lipiodol I-131 after curative resection/ablation of hepatocellular carcinoma

HPB, Issue 6 2008
K. M. Ng
Abstract Aim. A total of 329 patients with hepatocellular carcinoma have been treated at our unit since 1990. Following the randomized controlled trial in Hong Kong by Lau et al. in 1999, patients have been offered adjuvant lipiodol I-131. The aim of this study was to determine the effectiveness of adjuvant lipiodol I-131, following potentially curative surgery with resection and/or ablation, on overall and disease-free survival rates. Material and methods. The prospectively updated hepatocellular carcinoma database was analysed retrospectively. A total of 34 patients were identified to have received adjuvant lipiodol I-131 post-curative treatment with surgical resection and/or ablation. Patient demographics, clinical, surgical, pathology, and survival data were collected and analysed. Results. Three patients received ablation alone, 24 resection, and 7 resection and ablation. Of the 34 patients treated, there were 2 possible cases of treatment-related fatality (pneumonitis and liver failure). Potential prognostic factors studied for effect on survival included age, gender, serum AFP concentration, Child-Pugh score, cirrhosis, tumor size, portal vein tumor thrombus, tumor rupture, and vascular and margin involvement. The median follow-up duration was 23.3 months. The overall median survival was 40.1 months, while the overall survival rates at 1, 2, 3, and 4 years were 87.1%, 71.7%, 60.7%, and 49.6%, respectively. Median duration to recurrence was 22.3 months. Conclusion. Administration of adjuvant lipiodol I-131 is associated with good overall survival. [source]

Alpha-fetoprotein producing uterine corpus carcinoma: A hepatoid adenocarcinoma of the endometrium

PATHOLOGY INTERNATIONAL, Issue 10 2000
Hiroshi Toyoda
A case of alpha-fetoprotein (AFP) producing endometrial carcinoma in a 60-year-old Japanese woman is presented. The patient complained of abnormal vaginal bleeding of 10 days' duration. On admission a uterine corpus mass and high serum AFP concentration (31950 ng/mL) was noted. There was no tumorous lesion in any other organ radiographically and endoscopically. Histologically, the biopsy specimen taken from the uterine mass showed a poorly differentiated endometrial carcinoma and a radical hysterectomy was subsequently performed. The postoperative serum AFP value transiently decreased with chemotherapy, however, lung metastases were found and the patient died 12 months following surgery. The resected uterus had a necrotic tumor, 6 × 5 × 4 cm in size, filling the endometrial cavity, characterized by exophytic growth with infiltration in the myometrium. Histologically, the tumor was composed of the main medullary carcinoma area with microcysts and admixed small areas of well-differentiated endometrioid adenocarcinoma, accompanied by a smooth transition with one another. In both the areas, the tumor cells had immunoreactive AFP, alpha-1-antitripsin, albumin, transferrin, carcinoembryonic antigen, CA19-9, and epithelial membrane antigen. There was no histologic evidence for a germ cell tumor. Based on these findings, this uterine corpus tumor was regarded as hepatoid variant of endometrial carcinoma. Although the histogenesis remains controversial, we assume the hypothesis that the tumor may arise in the endometrium per se in association with abnormal differentiation of muellerian duct elements.

Hepatoblastoma in a child with progressive familial intrahepatic cholestasis

PEDIATRIC TRANSPLANTATION, Issue 6 2005
A. Richter
Abstract:, End-stage liver cirrhosis because of metabolic or infectious diseases predisposes to hepatic malignancies like hepatocellular carcinoma. We report the first case of hepatoblastoma incidentally detected in the explanted liver of a 2-yr-old child undergoing liver transplantation for cirrhosis because of progressive familial intrahepatic cholestasis (PFIC). The diagnosis was difficult to obtain. The hepatoblastoma was not seen on ultrasound examination of the cirrhotic liver. As we could confirm retrospectively, alpha fetoprotein (AFP) was found elevated prior to transplantation. Two years after successful transplantation, there are no signs of malignancy detectable by clinical and radiological methods. We conclude from this case that PFIC may induce hepatoblastoma and that children with liver cirrhosis should undergo routine screening of serum AFP concentration. [source]
