Serum alpha-fetoprotein (AFP) levels were measured by radioimmunoassay in 89 healthy adult Chinese, 170 patients with histologically verified non-malignant liver diseases, and 14 hepatitis B surface antigen (HBsAg) carriers with normal liver histology. In 97% of the healthy adults, AFP levels were under 20 ng/ml, which is then regarded as the normal upper limit. Cases with supranormally elevated AFP levels ranged from 15-51% in chronic hepatic disorders and were 33% in acute hepatitis. None of the healthy HBsAg carriers had abnormal AFP level. HBs antigenemia was found to be related to AFP elevation in chronic active hepatitis,
cirrhosis
, and acute hepatitis but not in chronic persistent hepatitis and healthy HBsAg carriers. The correlation could be demonstrated only when the sensitive third generation test was employed to define seropositivity of HBsAg. Events after hepatic injury induced by hepatitis B virus, rather than the HBs antigenemia itself, are probably responsible for the association. Whether the association of HBsAg and elevated serum AFP in these nonmalignant hepatic disorders contributes to the higher risk of subsequent development of hepatocarcinoma in Taiwan is unknown and requires further long-term longitudinal study.

The carcinogenicity of aflatoxin B1 (AFB1) has been under evaluation in nonhuman primates for the past 13 years. A total of 47 Old World monkeys, chiefly rhesus and cynomolgus, have received AFB1 i.p. (0.125 to 0.25 mg/kg) and/or p.o. (0.1 to 0.8 mg/kg) for 2 months or longer, and 12 are currently alive and without evidence of tumor. Thirteen of the 35 monkeys necropsied to date (37%) developed one or more malignant neoplasms, yielding an overall tumor incidence of 28%. Five of the neoplasms were primary liver tumors (2 hepatocellular carcinomas and 3 hemangioendothelial sarcomas), and 2 cases of osteogenic sarcoma were found. Other tumors diagnosed were 6 carcinomas of the gall bladder or bile duct, 3 tumors of the pancreas or its ducts, and one papillary Grade I carcinoma of the urinary bladder. The tumors developed in animals receiving an average total AFB1 dose of 709 mg (range, 99 to 1354 mg) for an average of 114 months (range, 47 to 147 months). Fifteen of the 22 necropsied monkeys (68%) without tumor showed histological evidence of liver damage, including toxic hepatitis,
cirrhosis
, and hyperplastic liver nodules. These animals had received an average total AFB1 dose of 363 mg (range, 0.35 to 1368 mg) for an average of 55 months (range, 2 to 141 months). Our results indicate that AFB1 is a potent hepatotoxin and carcinogen in nonhuman primates and further support the hypothesis that humans exposed to this substance may be at risk of developing
cancer
.

From 1971-1973, 1046 patients underwent laparoscopy in the gynecological department; 256 of the cases were surgical problems. In contrast to gastroenterological laparoscopy, surgical laparoscopy was performed in the operating room under general anaesthesia and everything prepared for immediate surgery. Major surgical interventions--if necessary--were performed immediately after laparoscopy. Indications for surgical laparoscopy were the following: preoperative evaluation of nature, extent and eventual metastases of tumors. Preoperative differentiation of acute and chronic appendicitis from other affections, particularly in younger female patients. Suspected intraabdominal hemorrhage of traumatic or non-traumatic origin. Evaluation of pathological palpatory findings in the abdominal cavity. Differential diagnosis of chronic relapsing intraabdominal complaints of unknown origin. Differential diagnosis of putrid, tuberculous or carcinomatous peritonitis with eventual biopsy. Preoperative evaluation of questions concerning surgery of liver, gallbladder or pancreas in connection with occlusive jaundice,
hepatic cirrhosis
or
malignancy
. The results of this study show, that by laparoscopy in over 50% of the patients, major surgical interventions could be avoided. Contraindications were primarily limited to pulmonal or cardiac insufficiency. The only complication (intestinal perforation), was adequately dealt with under the given operative conditions.

Out of 2,500 patients who underwent laparoscopy 772 (30.89%) had ascites;
liver cirrhosis
underlay it in 57.78%, peritoneal carcinosis in 26.29%, primary and metastatic carcinoma, respectively, in 12.95%, tuberculous peritonitis in 1.42%, more rarely other diseases.
Liver cirrhosis
, malignant tumours and the other hepatic affections with concomitant ascites in their course can certainly be diagnosed laparoscopically. Laparoscopy with oriented biopsy of peritoneum and liver is of decisive importance in differentiating peritoneal carcinosis from tuberculosis. In peritoneal carcinosis the diagnosis (as based in clinical and laboratory findings) coincided perfectly with the laparoscopic and histologic one in 24.5%, partially in 45.5%. In 30% there was no congruence at all. Laparoscopy and the test methods associated with it contributed to the accurate diagnosis of peritoneal carcinosis in 75.5% of the patients. Ovarian carcinoma (20.9%) and
cancer
of the stomach (16.3%) underlay peritoneal carcinosis most frequently, other diseases by far more seldom.

A retrospective survey organized by the Spanish Association for Digestive Endoscopy among its members has revealed that a correct diagnosis of primary liver cancer could be made by guided biopsy during laparoscopy in 153 of 208 cases. A diagnosis of
malignancy
was made in 103 of 145 cases of carcinoma associated with
cirrhosis
and in 50 of 63 cases without
cirrhosis
, but in the latter, the lesions were endoscopically indistinguishable from metastatic nodules in most instances. Biopsy was positive in 88% of all suspicious cases. Carcinomatous invasion of seemingly benign cirrhotic nodules could be demonstrated in 22 other patients.

Thirty-nine patients with focal defects on the technetium liver scan were rescanned using 111-In chloride. Of 20 patients with hepatic
malignancy
, 11 had positive indium scans. None of the 19 with focal cirrhotic fibrosis had a positive indium scan although 5 of these had primary tumor. Thus, a positive indium scan suggests that the defect is malignant. A negative indium scan is less helpful, failling to distinguish between neoplasm and focal
cirrhosis
. Positive uptake in an extrahepatic primary neoplasm and negative uptake in the liver suggest that the hepatic lesion is not neoplastic.

The age-standardized incidence rate of primary liver cancer (PLC) in Geneva was 9.7 per 100,000 in males, a figure four or five times higher than incidence rates reported elsewhere in Europe . These PLC's were often associated with
cirrhosis
and alcoholism. This indicated that the toll of PLC related to alcoholism and to alcoholic cirrhosis may be greater than anticipated.

Studies were made on the oncogenic response of 3086 young chicks to i.v. inoculation of MC29 avian leukosis virus from blood plasma of previous-passage birds or the supernatant fluid of cultures of chick embryo cells infected with strain MC29. Among the large variety of neoplasms of other tissues previously described, there occurred a high incidence of primary growths of the liver. Pathomorphology of the growths frequently differed greatly in both different hosts and the same bird, but some uniformity of the types of neoplasms was evident in many animals. Despite much variation in histopathology, the large proportion of growths could be grouped in several distinctive categories. Examinations by light and electron microscopy provided evidence of derivation of the tumors by alteration of hepatocytes originating principally in the portal regions as indicated by forms transitional from the parenchymal cells to the cells of the different types of growths. Neoplastic aspects of the growths were evident by infiltration and invasion of adjacent tissues, penetration of blood vessels, transplantability to other avian hosts (described in another report), and metastasis to distant organs including the lung, kidney, and spleen. There was no evidence of tumors arising from the biliary system, and growths of cells resembling the biliary type could be traced to altered hepatocytes. None of the findings suggested conversion of biliary-type cells to hepatocytes. Continued growth resulted in anaplastic and metaplastic changes in cell morphology and structural organization and in the formation of cartilage, osteoid, and sarcoma-like spindle-cell tumors of probable epithelial origin. Development of the growths wasnot associated with
cirrhosis
, and necrosis was limited to infrequent disseminated, essentially unicellular changes or necrobiosis of small groups of cells. The marked variations in the type of virus-induced growths demonstrated the remarkable capacity of cells morphologically inidistinguishable from the hepatocytes for the most diverse alterations in cell structure and tissue organization. This neoplastic response of hepatocytes to the MC29 strain constitutes the only demonstration thus far of the specific hepatocarcinogenic activity of an avian tumor virus.

The etiologic relationship of parasitic liver disease to primary liver cancer has long been debated. For this reason, a review of 4611 necropsies was carried out to determine the frequency with which hepatocellular carcinoma occurred in association with schistosomiasis. Of 227 cases of hepatocellular carcinoma, 24 (10.6%) were associated with schistosomiasis japonica. This was significantly higher than the incidence of this carcinoma without schistosomiasis (2.78%). The majority of the 24 cases exhibited the features of a mixed macronodular and micronodular
cirrhosis
(Gall's posthepatitic
cirrhosis
); this was super-imposed upon and caused a masking of schistosomiasis fibrosis. By radioimmunoassay hepatitis B antigen was positive in 27% of these cases. A review of the literature indicated that chronic schistosomiasis, on its own, is unlikely to be the cause of primary liver cell carcinoma. Histologic features resembling post-hepatitic
cirrhosis
combined with a high frequency of hepatitis B antigen suggest that viral hepatitis rather than S. japonicum is the more likely etiologic factor involved, or has a synergistic effect on carcinogenesis.
