RE: karzinom
Das ist eine seltene Histologie von Leberzellkarzinomen (s. Zusammenfassung unten). Es gibt natürlich keine Klinik, die auf Histologien spezialisiert ist. Sie müssen nach Zentren in abdomineller, speziell Leberchirurgie Ausschau halten, um zunächst die Frage der Operabilität zu klären. Wenn das nicht möglich ist, müssen Sie onkologische Zentren aufsuchen (Chemo-, Hormontherapie). Wenn der Tumor nicht zu ausgedehnt ist, lassen sich auch radiotherapeutische Verfahren diskutieren (wie z.B. an der Charité, Prof. Ricke, Augustenburger Platz 1, 13353 Berlin). Zur Klärung einer solchen Frage muss ein CT (oder MRT) zur Prüfung vorgelegt werden.

BACKGROUND/AIMS: To analyze, by means of immunocytochemistry, the cases of fibrolamellar variant of hepatocellular carcinoma (FLC), diagnosed in our Department. METHODOLOGY: The material comprised 4 FLC cases of tumors resected surgically. Besides the routine morphological assessment, we used a panel of immunohistochemical stainings including: hepatocellular cytokeratin, CK7, CK19, Ki67, PCNA, chromogranin A, synaptophysin, NSE, insulin, calcitonin, parathormon, CD34, EBV (LMP), Bcl2, cyclin D1. RESULTS: In 3 out of 4 cases, we observed co-expression of CK7 with hepatocellular CK. In addition, there was positive staining with some endocrine markers in the majority of patients. In one case, we found strong cyclin D1 immunoreactivity which correlated with EBV (LMP) immunoreactivity, in the same patient. The score of PCNA positivity varied between 15 and 90%. In all cases Ki67 was negative. CONCLUSIONS: The incidence of FLC, among all hepatocellular carcinomas diagnosed in our Department was 5.1%. In accordance with other reports, all our FLC cases were young patients without underlying liver disease. We were unable to find a correlation between FLC cellular immunophenotype, and histological and clinical markers of malignancy. In addition, it appears that PCNA is a better marker of cell-proliferation in FLC than Ki67. The significance of EBV infection in FLC requires further study.
