Tumor surgery in this field is no longer such a high risk as previously. Prolonged survival can be achieved by resection of hepatocellular carcinomas in non-cirrhotic livers (3-year survival 58%, n = 54 patients) and for colorectal liver metastases (3-year survival 44%, n = 124 patients). But surgery is rarely successful for the most frequent type of liver malignancy, the hepatocellular carcinoma in cirrhosis. Central bile duct carcinomas are now resected more frequently than in the past. Liver grafting seems indicated in special cases of liver and bile duct tumors. The future developments of operating on the in situ-perfused liver was discussed and the first operation on an ex situ-liver was demonstrated.

Cryosurgical treatment was applied to normal liver tissue of 13 clinically intact rats, with a view to investigating effects of freezing temperatures upon normal liver tissue. The animals were sacrificed after different intervals from surgery, and their liver tissue was macroscopically and histologically examined. Major postoperative complications were not observed but for one animal which died of wound healing disorder. The method seems to be suitable also for treatment of liver cell carcinoma or liver metastases.

A hybridoma producing monoclonal antibody (H11) directed to lactoneotetraosylceramide (paragloboside) has been established from spleen cells of a mouse immunized with paragloboside. The monoclonal antibody H11 (immunoglobulin M type) was selected from five clones showing different reactivities with paragloboside. The monoclonal antibody was highly specific to paragloboside and lacked reactivity with other glycolipids including glucosylceramide, lactosylceramide, globotriaosylceramide, globotetraosylceramide, gangliotriaosylceramide, gangliotetraosylceramide, and GalNAc beta 1-4[NeuAc alpha 2-3]Gal beta 1-4Glc beta 1-1Cer. However, the monoclonal antibody (H11) was found to bind to lactosamine-containing glycolipids at their terminals, such as i- and I-type glycolipids as well as paragloboside. A two-step sandwich radioimmunoassay method for paragloboside antigen in serum was established by using the monoclonal antibody. The mean paragloboside antigen concentration in the sera from 20 normal individuals was 25.3 ng/ml. If the cutoff value was set at 80.9 ng/ml [25.3 + 2 x 27.8 (SD)], only 1 of 20 healthy controls had an elevated paragloboside value in the serum, whereas sera from 9 of 12 (75.0%) hepatoma, 4 of 10 (40%) pancreatic cancer, 16 of 40 (40.0%) stomach cancer, and 6 of 10 (60%) lung cancer patients had elevated paragloboside values. Sera from 3 of 8 hepatitis patients and 7 of 10 liver cirrhosis patients were estimated to be positive but sera from 16 patients with benign disease had paragloboside levels lower than the cutoff value. A larger amount of the antigen was found in liver metastases from colorectal carcinoma compared to the normal counterpart. The antigen was also detected in the medium of various human cancer cells and meconium. However, the antigen in the sera, medium, meconium, and cancer tissue seemed to be associated with glycoprotein or lipoprotein, because most of the antigen activity was eluted in the void volume fraction on high-performance liquid chromatography with a gel filtration column.

A prospective study identified 45 patients with malignancy-related ascites among 448 ascites patients (10% of the total). Patients were categorized into five subgroups based on the pathophysiology of ascites formation. Each subgroup had a distinctive ascitic fluid analysis. Patients with peritoneal carcinomatosis but without massive liver metastases (53.3% of the patients with malignancy-related ascites) had a uniformly positive ascitic fluid cytology, high ascitic fluid protein concentration and low serum-ascites albumin gradient. Patients with massive liver metastases and no other cause for ascites formation (13.3% of the series) had a negative cytology, low ascitic fluid protein concentration, high serum-ascites albumin gradient and markedly elevated serum alkaline phosphatase. Those with peritoneal carcinomatosis and massive liver metastases (13.3% of the series) had a nearly uniformly positive ascitic fluid cytology, variable protein concentration, high serum-ascites albumin gradient and markedly elevated serum alkaline phosphatase. Chylous ascites (6.7%) was characterized by a milky appearance, negative cytology and an elevated ascitic fluid triglyceride concentration. Patients with hepatocellular carcinoma superimposed on cirrhosis (13.3%) had negative ascitic fluid cytology, low ascitic fluid protein concentration, high serum-ascites albumin gradient and elevated serum and ascitic fluid alpha-fetoprotein concentration. Two-thirds of patients with malignancy-related ascites had peritoneal carcinomatosis; 96.7% of patients with peritoneal carcinomatosis had positive ascitic fluid cytology. Ascitic fluid analysis is helpful in identifying and distinguishing the subgroups of malignancy-related ascites.

Major intraabdominal operations result in immunodepression. In addition, manipulation of malignant tumors may release tumor cells into the systemic and portal circulation. The additive effects of immunodepression and tumor cell release during surgical treatment for gastrointestinal cancer may increase the metastases of tumor to the liver. We, therefore, studied the inhibitory effect of immunoactivator OK-432 on the growth of the liver metastases in the perioperative period using a model in which rat ascites hepatoma AH-130 cells transplanted into the portal venous system consistently induce hepatic metastases. Forty-four male Donryu rats were assigned to a test group and a control group. The test group of 24 rats was treated with OK-432 (0.5 mg/day administered i.p.) for 7 days before tumor implantation, and the control group of 20 rats was treated with 0.2 ml of saline i.p. for the same number of days as the test group. The number of hepatic metastatic lesions at 14 days after tumor implantation amounted to 71.5 +/- 45.9 (SD) in the test group of 8 rats and 149.3 +/- 61.9 in the control group of 8 rats. The mean values of survival days after tumor implantation in the test group of 9 rats and the control group of 6 rats were 33.4 +/- 8.1 and 21.8 +/- 6.9, respectively. The values of OKT4+ in peripheral blood T-cell subsets in the test group of 7 rats and in the control group of 6 rats were 51.9 +/- 7.0 and 41.8 +/- 7.2%, respectively. These data showed significant differences between the two groups. Perioperative immunoactivation with OK-432 pretreatment reduced the incidence of liver metastases developed in rats given injections of tumor cells. We believe that the perioperative period is critical for the implantation and growth of metastases and that correction of perioperative immunodepression may favorably affect the development of metastatic disease and survival. This model may have relevance to the adjuvant treatment of human gastrointestinal cancer.

The authors report two cases of spontaneous regression of pulmonary metastases from hypernephroma; this is an exceptional event that occurs in 0.8% of metastasized renal carcinomas; spontaneous regression in all cancers as a group occurs in 0.0014% of cases. The theories postulated up till now to explain this phenomenon are unconvincing. The authors suggest the possibility of tumorous emboli: this event, that occurs mainly in those carcinomas with a propensity for extension to veins, such as renal carcinoma, choriocarcinoma, hepatoma and liver metastases, does not necessarily give rise to a metastasis. The evidence that leads to advocate nephrectomy in metastasized renal carcinoma are recalled and discussed.

2,131 coded sera were obtained and tested according to the new 5'-NPDase-V isozyme test. On decoding, 99/126 (79%) samples of primary hepatoma, from the United States and other countries, were positive. In the U. S. group, 51/58 (88%) were positive, 23/58 (40%) had AFP higher than 20 ng/ml. In the non-U. S. group, 48/68 (71%) were positive for 5'-NPDase-V, as compared with AFP elevation in 45/68 (66%). 236/268 (88%) cases of cancer with known liver metastases were positive for 5'-NPDase-V. Of 1,040 cancer patients without liver scan or biopsy evidence of metastasis, 316 were positive. In a follow-up of this group of 316 cases, 109 underlying liver metastases were demonstrated by repeat scan or at autopsy within 3--6 months. All 166 sera from normal healthy persons were negative for 5'-NADase-V. Based on this large panel, 5'-NPDase-V test is a sensitive and an important diagnostic aid for cancer patients, both as an early predictor for liver metastases, and a useful marker for primary hepatoma when no other primary sites are found and when there is no evidence of severe chronic liver disease such as cirrhosis.

Microheterogeneity of alpha-fetoprotein (AFP) present in the sera of 76 patients was studied by lectin affino-immunoelectrophoresis. Seventeen patients had benign liver disorders and the remaining 59 patients were treated for primary or secondary liver cancer or yolk sac tumour. By means of Con A, AFP was divided into two variants, while lentil lectin (LCA) made it possible to separate AFP in three variants. In some patients the relative concentrations of Con A and LCA AFP variants were similar; these patients were believed to produce AFP of the same 'profile'. Fourteen AFP profiles were observed by estimation of the area enclosed by precipitates corresponding to respective AFP variants. It was also possible to estimate the AFP profile on the basis of a simple visual analysis of the electrophoretic plates. The obtained results indicate that the AFP profiles of patients with cancer were variable. In spite of variations of the AFP profile in cancer patients, in most cases it was possible to differentiate primary liver cancer from yolk sac tumour and from liver metastases of cancer. In addition, in two-thirds of hepatoma patients the AFP profile was different from the profile observed in patients with benign liver disorders.

alpha 1-fetoprotein and Tennessee Antigen were evaluated in sera of 23 patients with hepatocellular carcinomas as well as in 20 patients with extrahepatic carcinomas and liver metastases. The diagnosis as histologically verified in all cases. Altogether 87% out of all hepatoma patients showed increased alpha 1-fetoprotein levels, whereby the concentrations were in the range which is highly suggestive of hepatoma in 65% of all patients with hepatoma. Tennessee Antigen concentrations were increased in 87% of hepatoma patients and in 85% of patients with metastatic liver cancer. Tennessee Antigen is an unspecific tumour marker, which can be used in control assessment during chemotherapy or after tumour resection and is of particular value in the follow up of those patients whose serum alpha 1-fetoprotein concentrations are normal or only slightly increased.

A monoclonal antibody, RL23/36, reacting preferentially with a determinant expressed on normal human hepatocytes is described. Use of an immunohistochemical technique on frozen sections from a range of 75 human liver biopsy specimens revealed that the determinant detected by RL23/36 was not expressed on hepatocytes from a number of patients with biopsy-proven liver disease. Although a normal staining pattern was observed in 28 of 29 biopsy specimens from patients with no evidence of liver disease, the antibody did not bind to hepatocytes in some cases of chronic active hepatitis (2/13), alcoholic liver disease (2/9), haemochromatosis (1/1), cirrhosis (1/2) and liver metastases (2/8). Furthermore, as in a previous study undertaken in the rat, the antibody failed to bind to tumour cells in the single human hepatoma observed in this study. These results suggest that further studies using RL23/36 may shed light on the pathogenesis of a number of liver diseases, including primary hepatocellular carcinoma.
