ObjectiveThe objective of this study was to analyze the specificity of detecting liver tumor cell dissemination by alpha-fetoprotein (AFP) mRNA in peripheral blood.
Summary Background DataAlpha-fetoprotein mRNA has been used for the detection of circulating micrometastatic tumor foci of hepatocellular carcinoma (HCC); however, the interpretation of the results has been equivocal.
MethodsSixty-four consecutive patients with malignant HCC (n = 20), liver metastases (n = 27), or nonmalignant (n = 17) liver diseases undergoing partial or total hepatectomy and orthotopic liver transplantation were included in this prospective study from January to July 1995. Peripheral blood samples were obtained before surgery, during surgery, and after surgery (range, 6-15 months). Total mRNA was extracted from nucleated cells, and cDNA synthesis and polymerase chain reaction amplification (nested polymerase chain reaction in one tube) were performed with specific AFP primers.
ResultsPreoperative AFP mRNA was detected in 20 patients (17%), of which 5 of 20 had HCC. lntraoperative assessment showed positive AFP mRNA values in a total of 34 patients (53%) with various causes, of which 8 of 20 (40%) had HCC, 17 of 27 (63%) had other malignancies, and 9 of 17 (53%) had nonmalignant diseases. Recurrent tumor in patients with HCC occurred in four cases after surgery (range, 6-15 months) and did not correlate with AFP mRNA positivity before surgery, during surgery, or after surgery.
ConclusionsAlpha-fetoprotein mRNA in peripheral blood is not a specific marker of circulating micrometastases from HCC, especially in the context of surgical treatment of HCC.

Conventional percutaneous liver biopsy in the early postoperative period, within 30 days, following liver transplantation may be impossible due to coagulopathy and/or ascites. The use of transjugular liver graft biopsy (TJLB) in this setting is an attractive alternative in that a tissue diagnosis can be obtained despite the relative contraindications for percutaneous biopsy during this period. During the early posttransplant period, 124 TJLBs were performed in 105 liver patients, the majority (89%) of whom had standard liver transplantation without preservation of the native inferior vena cava; the others (11%) had the native inferior vena cava intact. The technical success rate was 87%, with adequate specimen for definitive diagnosis in most instances (86%), which included both rejection (61%) and nonrejection (39%) diagnoses on final histopathology. The biopsy diagnosis influenced clinical management in the majority of cases (65%), with decisions made to perform retransplantation (3%), to influence initiation of antirejection therapy (59%), and to institute antiviral therapy (3%). There was no morbidity or mortality associated with TJLB and it is feasible, safe, and effective in the early period after liver transplantation.
Background. Uterine leiomyosarcoma (LMS) is a rare diagnosis, which is seldom cured when it recurs with metastatic disease. We evaluated patients who present with first time recurrence treated surgically to determine prognostic factors associated with long-term survival. Methods. Over a 16-year period, 41 patients were operated on for recurrent uterine sarcoma. Data examined included patient age, date of initial diagnosis, tumor histology, grade at the initial diagnosis, cytopathology changes in tumor activity from the initial diagnosis, residual tumor after all operations, use of adjuvant therapy, dates and sites of all recurrences, and disease status at last followup. Results. 24 patients were operated for first recurrence of metastatic uterine LMS. Complete tumor resection with histologic negative margins was achieved in 16 (67%) patients. Overall survival was significantly affected by the FIGO stage at the time of the initial diagnosis, the ability to obtain complete tumor resection at the time of surgery for first time recurrent disease, single tumor recurrence, and recurrence greater than 12 months from the time of the initial diagnosis. Median disease-free survival was 14 months and overall survival was 27 months. Conclusion. Our findings suggest that stage 1 at the time of initial diagnosis, recurrence greater than 12 months, isolated tumor recurrence, and the ability to remove ability to perform complete tumor resection at the time of the first recurrence can afford improved survival in selected patientsat the time of the first recurrence can afford improved survival in selected patients.
