Serum gamma-glutamyl transferase (GGT, EC. 2.3.2.2. was measured in 173 patients with diseases of the hepatobiliary system (including metastatic cancer) and in 90 patients who were subsequently shown to have primary diseases of other etiology. All patients had been selected because they had abnormal alkaline phosphatase, aspartate aminotransferase or bilirubin on SMA 12/60 screening. Serum GGT was elevated in 97% of patients with primary hepatobiliary disease. The magnitude of the increase in GGT was variable in all groups and was unhelpful in differential diagnosis, even between medical and surgical cases. Moreover, GGT was abnormal in 69 patients who did not have primary hepatobiliary disease (77%), an incidence higher than that for other enzyme tests performed. We conclude that because GGT was more susceptible than other tests to spurious elevation in the absence of hepatobiliary disease and was unhelpful in differential diagnosis, it has little value apart from monitoring alcohol abuse and enzyme induction.

From June 1981 to June 1989 we diagnosed 174 cases of hepatocellular carcinoma (HCC) at our institution (Piacenza, Northern Italy). Average age was 65.6 years; male to female ratio 3.4. 149 patients were cirrhotic (85.6%); alcohol abuse was present in 88/169 (52.1%); in 53/145 patients all hepatitis B virus markers were negative. Alpha-fetoprotein showed a low diagnostic sensitivity (values above 500 ng only in 49/169 or 29.0%). We used ultrasound (US) examination with a very high identification rate in all cases; pathological diagnosis was achieved by US guided fine-needle aspiration biopsy in 135 patients; in 13, by laparoscopy-histology. Metastases were found in 24/169 cases (14.2%); a second malignancy was diagnosed in 13/169 (7.7%): the most common association was HCC-non-Hodgkin lymphoma. Only 14 patients could be referred to surgery, which significantly improved prognosis.

One hundred consecutive cases of hepatocellular carcinoma (HCC) in cirrhosis observed at autopsy were studied and their pathological aspects were compared with those reported in the literature. The results, which are representative of HCC epidemiology in a geographical area where cirrhosis is mostly due to alcohol abuse, show that similarities in the architectural pattern of HCC and weight of the liver exist between our material and samples with different aetiology and epidemiology. A relationship between the histological grade of HCC and its propensity to metastasize was demonstrated. The reported better prognosis of clear cells per se could not be confirmed, although clear cell HCC occurred exclusively in grade 2. It was also demonstrated that the relationship between grading and staging was strongly influenced by the association of HCC with cirrhosis, which is a fact that is usually overlooked by the common staging (and grading) methods.

17 years ago, selective IgA deficiency was diagnosed in a 45-year-old woman suffering from dermatitis ulcerosa. In 1984, this patient developed oral cancer with metastases in the regional lymph nodes. Her long-term history of nicotine and alcohol abuse in combination with IgA deficiency seemed to be a risk factor for oral malignancy.

The pathologic findings of 232 consecutive cases of hepatocellular carcinoma (HCC) autopsied during the past ten years at Kurume, Japan, were analyzed from the point of view of global epidemiology, in relation to clinical feature, and in regard to incidence, age, sex, etiologic factors, size of liver, changes in noncancer parenchyma, gross type of tumor, extrahepatic metastases, intravascular and intraductal growths, cancer cell histology, hepatitis B surface antigen (HBsAg) in hepatocytes and cancer cells, liver cell dysplasia, and frequency and clinicopathologic characteristics of minute HCC. Furthermore, postmortem hepatic arteriography and portography were done in 152 livers for comparison with gross anatomy and celiac angiograms. It was found that: (1) epidemiologically, HCC in Japan is distinct from that in the West that it is frequently encapsulated, livers are generally small because of frequent and advanced cirrhosis and small cancer, minute HCC, is not uncommon at autopsy, cirrhosis most commonly associated is the one with thin stroma and medium size nodules, and micronodular cirrhosis is very rare despite frequent alcohol abuse; (2) HCC is increasing in incidence; (3) HBsAg is frequently found in parenchyma; (4) liver cell dysplasia is indirectly related to HBsAg with no evidence for premalignancy; (5) the lung is the most frequent site of metastasis but peritoneal dissemination is unusual; (6) intraportal tumor growth is very common and the hepatic vein is less frequently affected; (7) growth in the major bile duct is frequently associated with intraportal growth and clinically presents as obstructive jaundice; and (8) tumor is supplied solely by arteries and celiac arteriograms are closely correlated with gross pathologic findings.

Despite the steadily increasing number of patients suffering from squamous-cell carcinomas of the oropharyngeal region, little is known about the molecular steps involved in the induction of these neoplasms. We investigated oropharyngeal cancers from 38 patients for mutations in the p53 tumour-suppressor gene. The majority of patients (74%) had a history of tobacco and alcohol abuse. Five had lymph-node metastases, 3 had multiple primary carcinomas and 2 presented with multiple primary tumours and lymph-node metastases. Exons 5 through 8 of the p53 gene were screened by single-strand conformation polymorphism analysis followed by direct DNA sequencing. A total of 16 tumours (42%) contained point mutations which were scattered throughout exons 5 to 8. Most mutations (56%) were transitions, predominantly G-->A. Among the transversions, G-->T mutations prevailed; these have also been found in smoking-related lung cancer. One carcinoma of the soft palate showed a mutation which was retained in a lymph-node metastasis. In another patient, 2 primary carcinomas had different mutations, indicating that they had developed independently. Similar results were obtained in a case with a p53 mutation in the third of 3 primary tongue carcinomas which developed over a period of 23 years. One lymph-node metastasis had a 12-bp deletion which was not detected in any of the primary malignancies. The frequent occurrence of p53 mutations in oropharyngeal carcinomas supports the view that they play a role in the initiation or progression of the malignant phenotype.

A case of hepatocellular carcinoma (HCC), which developed during chemotherapy for chronic myelogenous leukemia (CML), is presented. A 55-year-old Japanese man, who had received an alkylating agent for 16 years, was diagnosed as having HCC with clinically evident splenic metastases. The patient died of the HCC rupture three months after diagnosis. The autopsy revealed the HCC to have developed from the non-cirrhotic liver. In the present case, DNA damage due to the long-term chemotherapy with the alkylating agent for CML may have endowed the HCC induced by post-transfusion hepatitis and alcohol abuse with an aggressive proliferative potential. This is the first report on HCC in association with CML.

Three cases of primary pulmonary rhabdomyosarcoma in adults are presented. The patients were all men between the ages of 57 and 78 yr (mean 67.5). All patients presented with symptoms referable to their tumors, including cough, shortness of breath, pleuritic chest pain, and weight loss. In one patient, a history of tobacco and alcohol abuse was obtained. Anatomically, two tumors were located in the left upper lobe and one in the left lower lobe. Grossly, the tumors ranged in size from 6 to 11.5 cm and were tan-gray, firm masses with areas of necrosis and hemorrhage. Histologically, the tumors were characterized by a spindle cell proliferation admixed with areas showing a pleomorphic cell population with numerous rhabdomyoblasts and areas of hemorrhage and necrosis. Immunohistochemically, all three tumors showed strong positivity with desmin and myoglobin antibodies and negative staining with antibodies against keratin, epithelial membrane antigen, and S-100 protein. All patients had a fatal outcome. Two patients died a few days after admission with respiratory distress; the third one died 2 years after diagnosis with widely metastatic disease. Autopsy findings in all cases disclosed disseminated metastases to multiple abdominal and thoracic organs. Primary pulmonary rhabdomyosarcoma should be considered in the differential diagnosis of poorly differentiated pulmonary neoplasms in adults and should be distinguished from other primary and metastatic sarcomas.

Fibrolamellar carcinoma is a malignant hepatocellular tumor with distinct clinical and pathologic differences from hepatocellular carcinoma. It differs from hepatocellular carcinoma in demographics, condition of the affected liver, tumor markers, and prognosis. Fibrolamellar carcinoma characteristically manifests as a large hepatic mass in adolescents or young adults (without gender predominance). Cirrhosis; elevated alpha-fetoprotein levels; and typical risk factors for hepatocellular carcinoma such as viral hepatitis, alcohol abuse, and metabolic disease are typically absent. Fibrolamellar carcinoma is characterized pathologically by cords of tumor cells surrounded by abundant collagenous fibrous tissue arranged in a parallel or lamellar distribution. Fibrotic lamellae often coalesce to form a central scar. Fibrolamellar carcinoma characteristically appears on radiologic images as a lobulated heterogeneous mass with a central scar in an otherwise normal liver. Radiologic evidence of cirrhosis, vascular invasion, or multifocal disease--findings typical of hepatocellular carcinoma--is uncommon in fibrolamellar carcinoma. Imaging features of fibrolamellar carcinoma overlap with those of other scar-producing lesions including focal nodular hyperplasia (FNH), hepatocellular adenoma and carcinoma, hemangioma, metastases, and cholangiocarcinoma. FNH, in particular, may simulate fibrolamellar carcinoma, since both have similar demographic and clinical characteristics. Because some believe that radiologic diagnosis of FNH is possible, it is important to understand the imaging appearance of fibrolamellar carcinoma to avoid misdiagnosing this malignant tumor as a FNH.
