A 61-year-old male was admitted because of hemoptysis. He had a 9 year history of liver cirrhosis associated with HB viral chronic hepatitis. Physical examination revealed no abnormalities. Laboratory investigations revealed positive HBs antigen with normal alpha-fetoprotein. Chest X-ray film showed large mediastinal lymph nodes and an endobronchial polypoid mass in the distal end of the right main bronchus. The right main PA was narrowed due to compression by the mediastinal mass. Bronchoscopic examination revealed a polypoid mass in the right main bronchus. The biopsy specimen was histologically diagnosed as undifferentiated large cell carcinoma. The patient developed respiratory failure, and died 3 weeks after admission. Autopsy revealed a small liver cancer of 1.3 cm diameter within the cirrhotic liver, associated with a small abdominal lymph node metastasis and large mediastinal lymph node swellings. Thromboembolism in the bilateral main pulmonary arteries was concluded to be the cause of death. The mediastinal mass which directly invaded into the right main bronchus had a close histological similarity with the liver cancer, showing undifferentiated carcinoma cells with bizarre nuclei and abundant cytoplasm. An immunohistological study revealed cells positive for alpha-fetoprotein in the mediastinal lymph nodes. The patient was diagnosed as having small liver cancer with mediastinal lymph node metastases. A survey of the literature revealed only a few cases of advanced hepatoma associated with prominent mediastinal metastases. This is the first reported case of small liver cancer presenting with large mediastinal lymph node metastases.

A retrospective analysis of 194 patients who underwent hepatic resection for primary or metastatic malignant disease from January 1962 to December 1988 was undertaken to determine variables that might aid the selection of patients for hepatic resection. Hepatic metastases were the indication for resection in 126 patients. The 5-year survival rate was 17 per cent. For patients with resected metastases from colorectal cancer (n = 104), the survival rate at 5 years was 18 per cent. The 5-year survival rate was 27 per cent when the resection margin was > 5 mm compared with 9 per cent when the margin was < or = 5 mm (P < 0.01). No patient with extrahepatic invasion, lymphatic spread, involvement of the resection margin or gross residual disease survived to 5 years, compared with a 23 per cent 5-year survival rate for patients undergoing curative resection (P < 0.02). The survival rate of patients with poorly differentiated primary tumours was nil at 3 years compared with a 20 per cent 5-year survival rate for patients with well or moderately differentiated tumours (P not significant). The site and Dukes' classification of the primary tumour, the sex and preoperative carcinoembryonic antigen level of the patient, and the number and size of hepatic metastases did not affect the prognosis. The 5-year survival rate for patients with hepatocellular carcinoma (n = 42) was 25 per cent. An improved survival rate was found for patients whose alpha-fetoprotein level was normal (37 per cent at 5 years) compared with those having a raised level (nil at 3 years) (P < 0.01). Involvement of the resection margin, extrahepatic spread and spread to regional lymph nodes were associated with an 8 per cent 5-year survival rate versus 44 per cent for curative resection (P < 0.005). The presence of cirrhosis, the presence of symptoms, and the multiplicity and size of the tumour did not affect the prognosis. The 5-year survival rate of 11 patients with hepatic sarcoma was 25 per cent. No patient with peripheral cholangiocarcinoma survived to 1 year in contrast to patients with hilar cholangiocarcinoma, all four of whom survived for more than 14 months.

Serum tumor markers, including carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), carbohydrate antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), cancer antigen 125 (CA 125), and tissue polypeptide antigen (TPA), were measured in 26 patients with skeletal metastases and 11 patients with primary malignant bone tumors. TPA, which was elevated in 16 patients (61.5%), was the most sensitive marker for detection of skeletal metastases. Combined measurement of these markers was useful in detecting skeletal metastases from primary lesions, although tumor markers had little organ specificity. In addition, skeletal metastases could be completely differentiated from primary lesions by the use of multivariate discriminant analysis of markers. The most and least powerful discriminating factors were AFP and CA 19-9, respectively. On multidimensional scaling, the distance between AFP and CEA was longest, with the other markers scattered between them. Expression of individual markers can not be linked to that of other markers.

Tumor markers are antigens which can be associated with certain malignancies. A variety of markers have been demonstrated in genitourinary tumors. The best known examples are human chorionic gonadotropin (bHCG) and alpha-fetoprotein (AFP) for testicular tumors, prostatic acid phosphatase (PAP) and prostatic specific antigen (PSA) for prostatic cancer. The plasma levels of these substances are influenced by the tumor mass and therefore by the tumor stage. Markedly elevated plasma levels can be demonstrated when metastases are present, although a few patients without metastases may elaborate abnormal amount of markers. The removal of the primary tumor leads to a fall to normal levels: a still increased level indicates residual primary tumor or the presence of metastases. Measurements of markers are also of value in estimating the effects of medical treatment and in detecting local or distant recurrences.

The case of a female patient with an alpha-fetoprotein (AFP)-producing acinar cell carcinoma of the pancreas is reported, and 28 cases in the literature are reviewed. In our case, the serum AFP level declined drastically after removal of the tumor, but increased when widespread metastases appeared. AFP was detected in the cytoplasm of the cancer cells by immunohistochemical staining. Immunoelectron microscopic studies revealed AFP on the endoplasmic reticulum of the cancer cells. Of the 28 cases with AFP-producing pancreatic cancer, liver metastases were identified in 21 cases (76% overall). There was no correlation between the serum AFP level and liver metastases. Immunohistochemical studies revealed localization of AFP at the primary lesion in 6 out of eight cases tested. In cases of AFP-producing pancreatic cancer, serum AFP levels are useful for the diagnosis and as a marker for evaluating recurrent disease and therapeutic response, and for the management of gastrointestinal disease it should be remembered that some pancreatic cancers produce AFP.

Gliomatosis peritonei (GP) is a rare occurrence associated exclusively with ovarian teratoma (OT), in which numerous metastatic nodules composed mainly of mature glial tissue are studded on the peritoneum, omentum, and bowel wall. Two female patients (aged 5 years and 14 years) are reported. Various preoperative examinations confirmed a large abdominal teratoma with normal alpha-fetoprotein and beta-HCG. The OT was excised and partial omentectomy and incidental appendectomy were performed to remove as many metastatic nodules as possible. Pathological examinations including immunostains for glial fibrillary acidic protein showed predominantly mature glial tissue in the OT and in the metastatic nodules. An addition, chemotherapy was given to one of them, but both were well without recurrent diseases 17 months and 12 months postoperatively, respectively. The outcome of these two cases, in contrast to advanced malignancy in widespread intraperitoneal metastases of any other kind, supports the concept of benign nature of GP and a conservative surgical approach to this rare disorder.

If conventional treatment modalities have failed in hepatoblastoma patients and no distant metastases can be demonstrated therapy with radionuclide agents can be considered. In 6 patients diagnostic technetium-99m (99mTc)-disofenin and two iodine-131 (131I)-rose bengal scans were made. 2 patients demonstrated specific uptake of disofenin. One of these had a positive scintigram with radiolabelled rose bengal. This patient was subsequently treated with 1.1 GBq 131I-rose bengal. No toxicity was observed. A clear decrease in the level of alpha-fetoprotein indicated a response and demonstrated that this radiopharmaceutical can be used for tumour targeted radiation therapy in selected patients with therapy resistant tumours.

Recombinant interleukin-2 (rIL-2) and adriamycin were administered systemically to treat nine patients (age 15.5-68 years, mean 48.9 years) with far advanced primary hepatocellular carcinoma. Three patients were newly diagnosed, and the remaining patients had received surgery, transcatheter arterial embolization, chemotherapy and other treatments but without improvement. RIL-2 was given at a dose of 10,000 to 30,000 units/kg every 8 hours for consecutive 9 days, and on the fifth day, a single dose of adriamycin 30 to 60 mg/M2 was administered. Four patients interrupted the immunotherapy because of severe intolerable side effects, 4 patients completed one course and the remaining one received 2 courses of treatment. Various adverse reactions were encountered, however, they subsided promptly after stop of therapy. All patients failed to respond to the regimen. Primary hepatic tumors continued to enlarge in 8 patients and remained unchanged in one, and pulmonary metastases also increased in size and number in 4 patients. Transient decrease in serum alpha-fetoprotein was found in 6 patients. These results suggests that systemic IL-2 immunotherapy, even in combination with chemotherapy, is not effective for the treatment of far advanced hepatocellular carcinoma. However, in viewing of its immune amplifying effect, rIL-2 in combination with other treatment modalities may still be worth trying in early stages of hepatocellular carcinoma.

A 59-year-old demented Japanese man who was proven to have high titer of serum alpha-fetoprotein (AFP) and carcino-embryonic antigen (CEA) was admitted to our hospital. Neurological examinations revealed moderate dementia with deterioration and loss of memory, and decreased deep tendon reflexes in all extremities. Sensory disturbances were not obvious. There were no significant changes in the usual laboratory findings including CSF, except for elevated serum AFP and CEA. Three months after admission, he died of gastric cancer and its metastases in liver and lymph nodes. Post-mortem examination in the central nervous system (CNS) revealed many senile plaques and neurofibrillary tangles throughout the cerebral cortex and hippocampus. There was marked loss of neurons in the hippocampus. All the neuropathological findings in the CNS were consistent with those in Alzheimer disease. In the peripheral nervous system, necrotizing arteritis was found throughout the length of sciatic nerve. Large myelinated fibers seemed to be preferentially degenerated with proximo-distal gradient. Teased fiber preparation revealed de/remyelination and axonal degeneration more frequently at the distal portion. Immunohistologically, the serum IgG of this patient specifically reacted to the endothelial cells of all vessels in control organs, which strongly suggested the autoimmune mechanism for the necrotizing arteritis in this patient. The pathogenetic role of this antibody for necrotizing arteritis, found selectively in the peripheral nervous system, still remained unclear. However, paraneoplastic neuropathy due to necrotizing arteritis is a distinct entity in addition to common form of paraneoplastic subacute sensory neuropathy.

Chemotherapy is the only effective method of treating unresectable hepatoblastoma. Most protocols require the administration of multiple highly toxic agents. We evaluated the ability of single-agent high-dose cis-platinum (HD-CDDP) to shrink unresectable primary hepatoblastoma to allow resection. Seven children aged 11 to 72 months had unresectable hepatoblastoma based on size and location. Initial alpha-fetoprotein (AFP) levels were between 4,900 and 1,840,000 ng/mL (mean, 555,900 ng/mL). Chest computed tomography (CT) scans obtained before beginning HD-CDDP therapy showed multiple or bilateral lung masses in 3 patients. Chemotherapy for each of the 7 children consisted of only HD-CDDP, 150 mg/m2, at 3-week intervals. HD-CDDP was stopped and prompt resection performed when AFP levels ceased to decline significantly (n = 4; mean nadir, 18,600); the corrected creatinine clearance decreased below 60 mL/min (n = 2); or, in one case, significant hemorrhage occurred within the tumor. Therefore, the number of HD-CDDP doses given preoperatively varied between 1 and 7 (mean, 3). No children required dialysis. Tumor cells in the bone marrow of one child disappeared completely after one dose of HD-CDDP. Follow-up CT scans showed complete resolution of the pulmonary metastases in 2 children, a partial response in the third, and a marked reduction of primary tumors to resectable sizes. Six children underwent tumor excision with adequate margins; parents of the seventh child refused permission for surgery. There were 2 operative deaths, 3 deaths due to local or distant disease, and 2 patients survived (postoperative follow-up, 22 and 14 months).(ABSTRACT TRUNCATED AT 250 WORDS)
