Pleural effusion, secondary to a metastasis from a malignant hepatoblastoma, was diagnosed in a 3-year-old Appaloosa gelding. Severe hemorrhagic transudate in both pleural cavities resulted in acute onset of labored breathing, tachypnea, tachycardia, and jugular vein pulsation. Results of ultrasonography and radiography of the ventral lung field and cranial portion of the abdomen initially were nondiagnostic, as were results of cytologic examination of peritoneal fluid and tracheal wash specimens. Moderately high serum gamma-glutamyl transferase and alkaline phosphatase activities, despite normal hepatocyte-specific enzyme (sorbital dehydrogenase) activity, were indicative of biliary stasis without hepatocyte destruction. The horse was euthanatized. Necropsy revealed a 47-kg hepatoblastoma, with metastases in the lungs and intestines.

Thirteen patients with hepatic tumors, from the Boston Center for Liver Transplantation, have been transplanted among a total of 169 recipients. Ten were transplanted primarily for tumor, while three other patients harbored incidental tumors. Two perioperative deaths occurred (15%). Eight patients had hepatocellular carcinoma, one hepatoblastoma and four bile duct (Klatskin) tumors. Two of the bile duct cancers recurred with patient deaths at 9 and 10 months. The remaining nine patients are alive from between 1 month and 36 months postoperatively. A selected review of the literature allowed analysis of follow-up on 185 patients transplanted for tumor. Overall, the proportion of patients transplanted for tumor was 16%. Fifty-two percent of patients had hepatocellular carcinomas (HCC), 24% cholangiocarcinomas, 10% other primary liver tumors, and 14% metastatic hepatic tumors. Median survival for HCC was 1 year; 90-day mortality was 30%. Actuarial survival for 1, 2 and 3 years was 49%, 37% and 30% respectively. Fibrolamellar HCC and incidental HCC had significantly better results than other HCC. Tumor recurrence was present in 72% of autopsies after 90 days. Transplantation for HCC has satisfactory results in selected patients and may be improved by adjuvant chemotherapy. The median survival with cholangiocarcinomas was 8 months; 90-day mortality was 40%. Actuarial survival for 1 year was 36%. Recurrence was present in 100% of autopsies after 90 days. Survival after transplantation for this tumor was similar to that observed in patients not undergoing surgical treatment. Median survival for 18 other primary hepatic tumors was 16 months. Transplantation in carefully selected patients with these other primary tumors appears warranted. Although experience overall with transplantation for metastatic disease has been relatively unfavorable, each histological type must be considered independently.

Chemotherapy was used to treat 11 children with hepatoblastoma that was judged to be unresectable because of tumor tissue in both lobes of the liver (eight patients) or because of size of the primary tumor (three patients). Three with bilobar involvement also had metastatic disease. Adriamycin was used in all patients. In nine, it was used in combination with cisplatin. A combination of other agents was used in four of these children. After two to six cycles (mean, 4 cycles), eight primary tumors exhibited marked response with greater than 50% reduction in size. Metastases disappeared in two patients. Complete resection of residual tumor was attempted in eight cases, and was successful in seven. One patient died at the time of surgery during an extended right hepatectomy. Two children had anaplastic hepatoblastomas that did not respond to chemotherapy, and the children died. One responder with giant cell hepatitis died from a severe coagulopathy and bleeding during chemotherapy before surgery. With preoperative chemotherapy, seven of 11 children with "unresectable" hepatoblastoma are now alive without disease 4 to 42 months following successful resection.

A 19-year-old female had ascites, an enlarged liver, pelvic masses, and an alpha-fetoprotein level of 397,000 micrograms/L with a normal beta-human chorionic gonadotropin serum level. Abdominal exploration revealed a large solitary liver mass with bilateral ovarian masses, and bilateral salpingo-oophorectomy and wedge liver biopsy were performed. The tumor was composed of cords, nests, and pseudorosettes of polyhedral cells with eosinophilic cytoplasm and nuclei with prominent nucleoli. The clinical, light microscopic, and immunocytochemical features indicate that the primary liver neoplasm and ovarian metastases were a purely epithelial hepatoblastoma. To the authors' knowledge, this is the first reported case of this type.

During the last 4 yr, fine-needle aspiration cytology (FNAC) has been employed in 1,474 patients in 0-15-yr age group at our institute. Of these, 245 patients were found to have malignant disease, including primitive neuroectodermal tumors, hepatoblastoma, nephroblastoma, sarcoma, and epithelial malignancies. Four metastases from medulloblastoma and two each from astrocytoma and meningioma were confirmed without open biopsy. FNAC interpretation was easy when cytologic findings were correlated with relevant clinical and radiologic data.

A retrospective analysis, from 1965 to 1987, of 22 patients less than 18 years of age undergoing thoracotomy for pulmonary metastases from previously diagnosed malignancy, was performed. There were 15 males and seven females whose ages ranged from 8 months to 17, years. Ten patients had primary osteogenic sarcoma, five had Wilms' tumor, and seven had miscellaneous other tumors. A total of 41 thoracotomies were performed with no mortality. The overall survival rate was 54.5%, with an average survival of 6.2 years after initial diagnosis. The osteosarcoma group had a 50% survival rate after an average of 62 months from initial diagnosis, while the Wilms' tumor group had an 80% survival rate with a 100-month average. The remaining seven patients had a 29% average survival rate 62 months after diagnosis. Of the 12 patients undergoing wedge resections, two died upon follow-up 20 and 21 months after initial diagnosis. As opposed to the survivors in this group, both required more than four wedge resections upon initial thoracotomy. Two patients requiring extended resections, one for Ewing's sarcoma and one for hepatoblastoma, died 35 and 3 months after diagnosis, respectively. Of the eight patients undergoing lobectomy and/or segmentectomy, 75% died an average of 31.3 months after diagnosis. Ten patients had two or more thoracotomies for an average of 2.9, with a 40% survival rate. Of the 27% who presented with initial bilateral lung metastases, 33% survived. Forty-five percent of patients had a tumor-free interval of less than 12 months prior to thoracotomy, resulting in a 60% mortality rate.(ABSTRACT TRUNCATED AT 250 WORDS)

Delayed primary operation has been started since 1982 in our department and 19 cases of solid tumor in childhood were treated with this method. They included 11 cases of advanced neuroblastoma, 5 cases of hepatoblastoma and 3 cases of yolk sac tumor in sacrococcygeal area. We discussed effectiveness of preoperative chemotherapy to the primary tumor and metastatic lesions, the best timing of operation after chemotherapy and the operative technique in delayed primary operation. Preoperative chemotherapy were useful in almost all cases of delayed primary operation, so the primary lesion and lymph nodes metastases were removed easily. We recommended it was the best timing of operation when 2 or 3 courses of preoperative chemotherapy were finished. CUSA (Cavitron Ultrasonic Surgical Aspirator) was the useful instrument to remove the primary tumor and lymph node metastases completely in advanced neuroblastoma preserving both kidneys.

Twenty seven children aged 1 to 15 years were admitted from 1981 to 1987 for the investigation and/or the surgical treatment of a primary liver malignancy (25 hepatoblastomas and 2 hepatocellular carcinomas). All were submitted to preoperative multidrug chemotherapy. One child died from circulatory failure early after the diagnosis and two children considered to be non operable died also. A macroscopically satisfactory resection could be achieved in 24/27 cases. Sixteen out of these 24 children are alive and disease free, 11 of them with a follow-up over 2 years. Two of these 16 survivors underwent a second operation for resection of a local recurrence. Four children died after a massive unresectable hepatic relapse, two after a second relapse and a one after the onset of pulmonary metastases during her chemotherapeutic postoperative course. One further child is at yet in a critical situation because of a late small secondary hepatic relapse. Two factors contributed to improvement of survival an cure rates during the past ten years: 1. Routine preoperative chemotherapy, which may help in controlling the disease and greatly facilitates surgery by shrinking of massive tumors. 2. Better surgical management and especially the total hepatic vascular exclusion, used in 13 cases of this series. Three situations still have a poor outlook: 1. Hepatocellular carcinoma 2. Hepatoblastoma with a low response to chemotherapy 3. Multifocal tumors and those involving the main hepatic vessels. The feasibility of a liver transplantation in some selected cases is discussed.

This paper reports the relationship between serum cholesterol level and hepatoblastoma in nine patients. Four of the nine patients had a high (417-544 mg%) serum cholesterol. All of these patients were less than one year of age and had tumors of the epithelial type. Three of the infants died soon after being diagnosed. Three patients had a moderately elevated serum cholesterol (206-249mg%). One underwent primary hepatic resection. Two had nonresectable tumors that became resectable after chemotherapy. One died secondary to pulmonary metastases. The remaining two patients had a normal serum cholesterol level prior to treatment. Both patients had hepatic resection after chemotherapy and had no evidence of increased cholesterol postoperatively and are alive six years after diagnosis. From these data, it is suggested that the pretreatment level of serum cholesterol may be of prognostic significance in infants and children with hepatoblastoma.

DNR can be targeted to the liver by linking to galactosylated human serum albumin (AG). The linkage is stable in the blood stream and allows the release of active DNR after endocytosis of the conjugate by the target cells. Receptors for AG are present at the cell membrane of hepatocytes, primary human hepatoma cells and lung metastases. After i.v. administration of AG-DNR more than 70% of the drug is taken up by the liver and in rats 50% of DNR is eliminated in the bile after 16 h. Nude mice bearing human hepatoblastoma cells implanted s.c. were treated twice a week with a dose equivalent to 6.6 mg/kg of DNR either for the free drug or the conjugate AG-DNR. After 7 injections, tumor growth is inhibited in both case, however, the conjugate seems more active and is at least twice less toxic in terms of LD50. A phase I clinical trial of AG-DNR on 11 patients bearing hepatocarcinoma revealed that despite a transitory hyperthermia (37-38 degrees C) during the first day of the 4 day-perfusion, and modifications of hepatic enzymes in 3 cirrhotic patients, no hematologic and cardiac toxicity could be detected. A subjective response has been obtained in half of the patients with a decrease of plasmatic alpha-foetoprotein levels by more than 50% in 4 patients and one complete remission of more than 23 months with disparition of pulmonary metastases.
