Between 1982 and 1986, liver segmentectomies were performed in 19 patients with liver tumors, including ten hepatocellular carcinomas, six liver metastases, one cholangiocarcinoma, and two benign tumors. During surgery, patients received a mean (+/- 1 SD) of 1050 +/- 150 mL of packed red blood cells and 860 +/- 80 mL of fresh-frozen plasma. There were no operative deaths. The only complication was a prolonged leakage of ascites through the abdominal drain in one patient with cirrhosis. Seven patients with hepatocellular carcinoma were still alive at this writing, with a follow-up ranging from two months to four years. The four patients with metastases from colorectal carcinomas were alive after follow-up times ranging from six to 24 months. These results suggest that liver segmentectomy is a safe procedure and should be considered as the operation of choice for resection of limited liver tumors.

Transcatheter embolization with a relatively large amount (average, 17 mL) of iodized oil and doxorubicin hydrochloride with or without gelatin sponge particles was performed in 50 patients with hepatocellular carcinoma and in eight patients with liver metastases. After an intraarterial hepatic injection of an emulsion of iodized oil and doxorubicin hydrochloride, iodized oil was seen in the portal vein; the amount correlated with the amount that was injected, despite the lack of arterioportal shunting. Prominent portal vein appearances were seen in six of 21 cases (29%) given 10 mL or less of iodized oil, in 14 of 21 cases (67%) with 10-20 mL, and in 18 of 21 cases (86%) with more than 20 mL. Iodized oil may enter the portal vein through an arterioportal communication after pooling in the sinusoids.

Between April 1979 and March 1987 24 patients underwent 26 hepatic resections. Colorectal liver metastases constituted the largest group (n = 18), followed by hepatocellular carcinoma (n = 2), Echinococcal liver cyst (n = 1), cholangiocarcinoma (n = 1), and leiomyosarcoma (n = 1). The mean age was 41.8 +/- 14.6 years (range: 23-69 years). Fifteen women and nine men comprised the group. The operative morbidity was 21 per cent, the 30-day operative mortality was 8 per cent (two deaths). Both operative deaths occurred in patients with colorectal liver metastases. The 18 patients with colorectal liver metastases included ten women and eight men. The mean age was 59.1 +/- 6.5 years (range: 46-69 years). There were seven synchronous and 11 metachronous liver metastases. Carcinoembryonic antigen (CEA) was found elevated in 14 of the original primary colonic carcinomas, and in all but one patient with metachronous liver metastases. The mean time from colorectal carcinoma resection to occurrence of metachronous metastases was 17.1 +/- 5.8 months. To date, 10 patients have had recurrences of liver metastases after hepatic resection for colorectal liver metastases. The mean time of recurrence was 12.6 +/- 11.9 months. The size of the metastases was 3.8 +/- 3.2 cm (range: 0.2-17 cm). The mean number of lesions present was 1.5 +/- 1.0. The 1 year and 2 year actuarial survival rates were 87.5 and 43.8 per cent respectively. The longest survivor is alive 54 months after his hepatic resection for colorectal liver metastases and remains to this date disease free.(ABSTRACT TRUNCATED AT 250 WORDS)

Aspiration-biopsies under ultrasound guidance, using a fine needle (external diameter inferior to 1 mm) have been performed in 61 malignant hepatic tumors (group I) and 25 pancreatic carcinomas (group II). Malignancy was diagnosed in 83 p. 100 cases; in group I, the sensitivity is 87 p. 100; the difference between hepatocellular carcinoma and liver metastases could be made in 88 p. 100 cases and in case of metastases, the site of the primitive carcinoma could be suggested in 77 p. 100 cases. In group II, the sensitivity is 72 p. 100. No complications were noted.

Arterial infusion chemotherapy is commonly-used modality for controlling cancers located in specific regions. Previously we described a new method of intra-hepatic arterial catheterization through the left subclavian artery using a subcutaneously-implanted silicone reservoir. In the present paper, we report our experience using a low dose-intermittent intraarterial (i.a.) infusion chemotherapy. Since February, 1982, 70 patients including 44 cases of metastatic liver cancer, 16 cases of primary hepatocellular carcinoma and 10 cases of other gastrointestinal malignancies, have been treated with this low dose-intermittent i.a. infusion chemotherapy, the drugs used being as follows. 1) MMC 4 mg, 5-FU 500 mg, AraC 40 mg/2w, 2) MMC 4 mg/w, 3) 5-FU 500 mg/w, MMC 4 mg/2w, ADM 30 mg/4w. Here, we briefly review the effectiveness of this modality for controlling regional diseases including liver metastases. The average hospital-free interval was 156 days and partial responses were observed in 43% (21/49) of cases. Side effects during the therapy were only mild bone marrow suppression and anorexia, which were tolerable in out-hospital care. We also studied the pharmacokinetics of i.a. infusion into the liver in comparison with i.v. infusion using 99mTc-RBC, and found that the ratio of i.a. to i.v. with regard to trans-arterial drug delivery to the liver was 10.0. From the viewpoints of first pass effect and increased local concentration theory, this ratio suggests that the effectiveness of a low-dose anti-tumor agent administered intraarterially is not so low. Accordingly, we believe that low dose-intermittent i.a. infusion chemotherapy is beneficial as an induction and maintenance chemotherapy for patients with regionally located cancers because it is effective, safer and prolongs the hospital-free interval.

Technetium-99m galactosyl-neoglycoalbumin ( [Tc]NGA) is a radiolabeled ligand to hepatic binding protein, a receptor which resides at the plasma membrane of hepatocytes. This receptor-binding radiopharmaceutical and its kinetic model provide a noninvasive method for the assessment of liver function. Eighteen patients were studied: seven with hepatoma, eight with liver metastases, four with cirrhosis (two had concurrent hepatoma and one chronic active hepatitis), and one patient with acute fulminant non-A, non-B hepatitis. Technetium-99m NGA liver imaging provided anatomic information of diagnostic quality comparable to that obtained with other routine imaging modalities, including computed tomography, angiography, ultrasound, and [Tc]sulfur colloid scintigraphy. Kinetic modeling of dynamic [Tc]NGA data produced estimates of standardized hepatic blood flow, Q (hepatic blood flow divided by total blood volume), and hepatic binding protein concentration, [HBP]. Clinical correlation was by classical Child-Turcotte criteria (CTC). Significant rank correlation was obtained between [HBP] estimates and CTC scores (rs = -0.72, p = 0.001). This correlation supports the hypothesis that [HBP] is a measure of functional hepatocyte mass. The combination of decreased Q and markedly reduced [HBP] may have prognostic significance; all three patients with this combination died of hepatic failure within 6 wk of imaging.

Intraoperative ultrasonography was performed in 24 patients with single or multiple liver metastases of colorectal cancer, in 4 patients with a hepatocellular carcinoma, in 2 patients with an hepatic abscess and in one patient with a focal nodular hyperplasia and one with a liver hemangioma. In 9 of 32 patients with inflammatory or malignant liver disease the tumors were not palpable or visible. These hepatic lesions were localized by intraoperative ultrasound. In 5 cases preoperative unknown hepatic tumors were diagnosed by intraoperative sonography.

The presence of HBsAg was detected in the serum of 1 out of 13 patients with chronic hepatitis, in 2 out of the 7 patients with liver metastases, but in none of the 10 patients with hepatocellular carcinoma (HCC) investigated. HBsAg could be visualized by orcein staining in the liver cells of 66.6% of the HCC patients, in 50% of the patients with liver metastases and in 40% of the patients with liver cirrhosis. The prevalence of anti-HBs was low both in HCC patients and in the control groups. The possible significance of these findings is discussed.

To evaluate the diagnostic accuracy of fibronectin levels in ascites to differentiate malignant from non-malignant ascites, the authors studied 30 patients with sterile uncomplicated ascites in chronic liver disease, 18 patients with malignant ascites and four patients with spontaneous bacterial peritonitis. Fibronectin concentration was significantly higher in malignant ascites than in sterile ascites (P less than 0.001). High values (greater than 85 mg/l) were found in four of six cases of hepatocellular carcinoma in liver cirrhosis with negative cytologic examination, and in six of seven peritoneal carcinomatoses. Low values (less than 85 mg/l) were found in four patients with liver metastases and in one patient with intrahepatic biliary duct carcinoma in cirrhosis. In four patients with infected ascites, the fibronectin level was low. Among all other parameters (total protein concentration, lactate dehydrogenase, gamma-glutamyl-transpeptidase, pH, amylase, triglycerides, leukocyte count, and cytologic examination), fibronectin yielded the best degree of discrimination (diagnostic accuracy, 79%).

CT and ultrasound have completely replaced angiography in the diagnosis of focal liver lesions. However, angiography of the liver is still important for delineation of the vascular anatomy and enhancing diagnostic specificity, especially prior to hepatic surgery. CT angiography using water-soluble or oily contrast materials improves the diagnostic accuracy with regard to the number of lesions detected in patients with liver metastases or hepatoma. Both techniques reveal more lesions than do standard angiographic methods.
