title: Treatment of ruptured undifferentiated sarcoma of the liver in children: a report of two cases and review of the literature.
abstract: Undifferentiated (embryonal) sarcoma of the liver (USL) is a highly malignant tumor of early life. Treatment choices for USL, especially with intraperitoneal rupture, are uncertain. Outcomes have been almost uniformly poor until recently. We describe two 7-year-old girls treated for ruptured USL. In the more recent patient, operative biopsy was followed by three cycles of cisplatin (CDDP), adriamycin (ADR), and cyclophosphamide (CPM). A fluid-filled cavity in the tumor showed enlargement and was drained. Two cycles of CDDP, ADR, vincristine (VCR), and ifosfamide were accompanied by reduction in tumor size, and trisegmentectomy was performed. She has no evidence of disease 3.5 years after surgery. In the other patient, left lobectomy was followed by a less intensive regimen, including CPM, VCR, and fluorouracil. This patient died of dissemination within 5 months. In 170 reported pediatric patients with USL, the 2-year disease-free survival was 17%. For the 96 such patients reported since 1980, 2-year disease-free survival had improved to 27%. More aggressive chemotherapy has been associated with this change. Of 8 patients with tumor rupture whose details have been reported (including the 2 present patients) after resection of the tumor, 4 died, 1 was alive with disease, and 3 were free of disease at 8, 49, and 58 months, respectively, after diagnosis. Ruptured USL should be treated with combination chemotherapy including CDDP and ADR, as well as with curative resection.
