Growth of intrapleurally injected cells of immunogenic methylcholanthrene-induced rat sarcomas was suppressed by intrapleural injection of viable or 1 times 10-6 R radiation-sterilized BCG vaccine. As little as 10 mug moist weight of organisms was effective, and treatment could be given several days before or after tumour challenge. Pleural effusion growth of a moderately immunogenic ascitic hepatoma was also controlled by intrapleurally administered BCG. In contrast, BCG injected intravenously, subcutaneously or intraperitoneally was without influence on pleural tumour growths. Similarly, intraperitoneal growth of these tumours was suppressed only by intraperitoneal injection of BCG. With two other transplanted tumours, a chemically induced mammary carcinoma and a spontaneous sarcoma, both of which lack significant immunogenicity, BCG treatment of pleural and peritoneal growths was less successful and more variable. Nevertheless, these studies indicate the potential of this type of treatment of thoracic and peritoneal tumour deposits for possible clinical application in the treatment of malignant mesothelioma.

In an earlier phase I study, we reported that the maximal tolerated dose (MTD) of prochlorperazine (PCZ) given as a 15-min i.v. infusion was 75 mg/m2. The highest peak plasma PCZ concentration achieved was 1100 ng/ml. The present study was conducted to determine if PCZ levels high enough to block doxorubicin (DOX) efflux in vitro could be achieved and sustained in vivo by increasing the duration of i.v. infusion from 15 min to 2 h. The treatment schedule consisted of i.v. prehydration with at least 500 ml normal saline (NS) and administration of a fixed standard dose of 60 mg/m2 DOX as an i.v. bolus over 15 min followed by i.v. doses of 75, 105, 135, or 180 mg/m2 PCZ in 250 ml NS over 2 h. The hematologic toxicities attributable to DOX were as expected and independent of the PCZ dose. Toxicities attributable to PCZ were sedation, dryness of mouth, anxiety, akathisia, hypotension, cramps, and confusion. The MTD of PCZ was 180 mg/m2. Large interpatient variation in peak PCZ plasma levels (91-3215 ng/ml) was seen, with the plasma half-life (t1/2 alpha) being approximately 57 min in patients given 135-180 mg/m2 PCZ. The volume of distribution (Vd), total clearance (ClT), and area under the curve (AUC) were 350.1 +/- 183.8 1/m2, 260.7 +/- 142.7 l m2 h-1 and 1539 +/- 922 ng ml h-1, respectively, in patients given 180 mg/m2 PCZ and the respective values for patients receiving 135 mg/m2 were 48.9 +/- 23.76 l/m2, 33.2 +/- 2.62 l m2 h-1, and 4117 +/- 302 ng ml h-1. High PCZ plasma levels (> 600 ng/ml) were sustained in all patients treated with 135 mg/m2 PCZ for up to 24 h. DOX plasma elimination was biphasic at 135 and 180 mg/m2 PCZ, and a > 10-ng/ml DOX plasma level was maintained for 24 h. Partial responses were seen in three of six patients with malignant mesothelioma, in two of ten patients with non-small-cell lung carcinoma, and in the single patient with hepatoma. Our data show that PCZ can be safely given as a 2-h infusion at 135 mg/m2 with clinically manageable toxicities. The antitumor activity of the combination of DOX and PCZ needs to be confirmed in phase II trials.

Among the patients who were examined with bone scintigraphy between April 1985 and March 1991, there were 27 patients whose initial clinical manifestation was bone metastasis and who were surveyed for the primary tumor site. The primary tumor site could be identified in 20 patients (74%), consisting of 9 patients with lung cancer, 3 with prostate cancer, 3 with hepatoma, 2 with renal cancer, and one each with thyroid cancer, adrenal cancer, and pleural malignant mesothelioma. In 17 of the 20 patients, the primary site had been detected within two months after presentation. Examinations which were helpful in identifying the primary site included chest radiography, sputum cytology, abdominal sonography, serum prostatic acid phosphatase level and pathologic examination of biopsy specimens. 99mTc-PMT scintigraphy was useful in the diagnosis of the hepatoma when accumulation was observed at the metastatic sites. In 2 patients, lung cancer had been recognized using follow-up chest radiography 3 and 6 months after presentation, respectively. One patient was diagnosed at autopsy as having adrenal cancer. In 7 patients the primary site remains unknown. Histology examination of the biopsy specimen performed in 6 of these patients revealed 4 to be adenocarcinoma and 2 undifferentiated carcinoma. The average survival period of the 17 patients who died was 9.5 months. Four patients are alive, and the outcome in the remaining 6 could not be determined.

Cytokeratin 7 (CK 7) and cytokeratin 20 (CK 20) are low molecular weight cytokeratins. Their anatomic distribution is generally restricted to epithelia and their neoplasms. We surveyed 435 epithelial neoplasms from various organ systems by immunohistochemistry using CK 7 and CK 20 monoclonal antibodies. Expression of CK 7 was seen in the majority of cases of carcinoma, with the exception of those carcinomas arising from the colon, prostate, kidney, and thymus; carcinoid tumors of the lung and gastrointestinal tract origin; and Merkel cell tumor of the skin. The majority of cases of squamous cell carcinoma of various origins were negative for CK 7, except cervical squamous cell carcinoma, in which 87% of cases were positive. Approximately two thirds of cases of malignant mesothelioma were CK 7-positive. CK 20 positivity was seen in virtually all cases of colorectal carcinomas and Merkel cell tumors. CK 20-positive staining was also observed in cases of pancreatic carcinomas (62%), gastric carcinoma (50%), cholangiocarcinomas (43%), and transitional cell carcinomas (29%). The expression of CK 20 was virtually absent in carcinomas from other organ systems and in malignant mesothelioma. CK 7- and CK 20-negative epithelial neoplasms included adrenal cortical carcinoma, germ cell tumor, prostate carcinoma, renal cell carcinoma, and hepatocellular carcinoma.

Oxaliplatin is a third-generation platinum compound which has proven its efficacy alone or in combination with 5-fluorouracil (5-FU) and/or new anticancer drugs in advanced colorectal cancer. Compared to the amount of available data in this cancer, little is known about the use of oxaliplatin in non-colorectal gastrointestinal malignancies. (1) The preclinical activity of the drug alone or in combination; (2) the phase I studies (oxaliplatin alone or in combination with irinotecan, raltitrexed, gemcitabine, folinic acid and 5-FU); (3) the phase II studies developed in gastric, pancreatic, biliary tract, hepatocellular carcinoma and malignant mesothelioma; and (4) some of the ongoing trials with regard to non-colorectal gastrointestinal malignancies are reviewed in this paper. To date, oxaliplatin appears as a real candidate for clinical development in this field.

Five cases are reported in which malignant mesothelioma of the pleura and hepatocellular carcinoma co-existed in the same patient. The group included four men and one woman, aged between 58 and 86 years. The diagnosis was established at necropsy. In one case the association was clinically suspected. All mesotheliomas were asbestos-related. Liver cirrhosis co-existed in four cases, two of them positive for HCV markers. A lot of elements suggest that the above association is not a fortuitous coincidence. In particular, asbestos could favour liver cancerogenesis by inducing immune impairment.

Methyleugenol is used as a flavoring agent in jellies, baked goods, nonalcoholic beverages, chewing gum, candy, pudding, relish, and ice cream. It is also used as a fragrance in perfumes, creams, lotions, detergents, and soaps. Methyleugenol has also been used as an insect attractant in eradication programs and as an anesthetic in rodents. Methyleugenol was nominated for testing because of its widespread use and because of its structural resemblance to safrole, a known carcinogen, and isosafrole and estragole. Male and female F344/N rats and B6C3F1 mice received methyleugenol (approximately 99% pure) in 0.5% methylcellulose by gavage for 14 weeks or 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium, cultured Chinese hamster ovary cells, and mouse peripheral blood erythrocytes. 14-WEEK STUDY IN RATS: Groups of 9 or 10 male and 10 female F344/N rats were administered 0, 10, 30, 100, 300, or 1,000 mg methyleugenol/kg body weight in 0.5% methylcellulose by gavage 5 days per week for 14 weeks. A water control group of 10 male and 10 female rats received deionized water by gavage. All rats survived until the end of the study. The final mean body weights of 300 and 1,000 mg/kg males and of all dosed groups of females were significantly less than those of the vehicle controls. Erythrocyte microcytosis was demonstrated by decreased mean cell volumes in 300 mg/kg males and 1,000 mg/kg males and females. There was evidence of a thrombocytosis at all time points, demonstrated by increased platelet counts in the 100 mg/kg or greater groups. The serum activities of alanine aminotransferase and sorbitol dehydrogenase were increased in the 100 mg/kg or greater rats at various time points, suggesting hepatocellular injury. Additionally, bile acid concentrations were generally increased in the 300 and 1,000 mg/kg groups at all time points, consistent with cholestasis or altered hepatic function. A hypoproteinemia and hypoalbuminemia, evidenced by decreased total protein and albumin concentrations, occurred in rats in the 300 and 1,000 mg/kg groups at all time points. Liver weights of 100, 300, and 1,000 mg/kg males and 300 and 1,000 mg/kg females and testis weights of 1,000 mg/kg males were significantly increased. Increased incidences of liver lesions occurred in 300 and 1,000 mg/kg males and females and hepatocellular adenoma occurred in one 1,000 mg/kg male. The incidences of atrophy and chronic inflammation of the mucosa of the glandular stomach were significantly increased in rats administered 300 or 1,000 mg/kg. Increased incidences of adrenal gland cortical hypertrophy and/or cytoplasmic alteration in the submandibular gland occurred in the 100 mg/kg or greater groups. 14-WEEK STUDY IN MICE: Groups of 10 male and 10 female B6C3F1 mice received methyleugenol in 0.5% methylcellulose by gavage at doses of 0, 10, 30, 100, 300, or 1,000 mg/kg, 5 days per week for 14 weeks. A water control group of 10 male and 10 female mice received deionized water by gavage. All but one male and all females receiving 1,000 mg/kg died before the end of the study. The mean body weight gains of mice in the 300 mg/kg groups were significantly less than those of the vehicle controls. The only clinical finding was toxicity manifested as generalized morbidity in mice administered 1,000 mg/kg. Liver weights of 30, 100, and 300 mg/kg males and of 300 mg/kg females were significantly increased. Male mice administered 10 or 30 mg/kg had significantly lower cauda epididymis, epididymis, and testis weights; males receiving 100 mg/kg had significantly lower spermatozoal concentrations. Increased incidences of liver lesions occurred in 1,000 mg/kg males and 300 and 1,000 mg/kg females. The incidences of lesions of the glandular stomach were increased in one or more groups administered 30 mg/kg or greater. 2-YEAR STUDY IN RATS: Groups of 50 male and 50 female rats received methyleugenol in 0.5% methylcellulose by gavage at doses of 37, 75, or 150 mg/kg, 5 days per week for 105 weeks; groups of 60 male and 60 female rats received the 0.5% me60 female rats received the 0.5&percnt; methylcellulose vehicle only. Stop-exposure groups of 60 male and 60 female rats received 300 mg/kg in 0.5&percnt; methylcellulose by gavage for 52 weeks followed by just the 0.5&percnt; methylcellulose vehicle for the remaining 53 weeks of the study. Special study groups of 10 male and 10 female rats administered 36, 75, 150, or 300 mg/kg were designated for toxicokinetic studies. Survival and Body Weights: All 150 and 300 mg/kg males died before the end of the study, and survival of 150 mg/kg females was slightly less than that of the vehicle controls. Mean body weights of all dosed groups of rats were less than those of the vehicle controls throughout most of the 2-year study. Pathology Findings: Chemical-related liver neoplasms occurred in all dosed groups of rats and included hepatocellular adenoma, hepatocellular carcinoma, hepatocholangioma, and hepatocholangiocarcinoma; at 2 years, there were positive trends in the incidences of hepatocellular adenoma, carcinoma, and adenoma or carcinoma (combined) in core study rats and in the numbers of rats with multiple liver neoplasms. Nonneoplastic lesions included eosinophilic and mixed cell foci, hepatocellular hypertrophy, oval cell hyperplasia, cystic degeneration, and bile duct hyperplasia (females); the incidences of these lesions in dosed groups of male and female rats were increased at 6 months, 12 months, and/or 2 years. Chemical-related neoplasms and nonneoplastic lesions of the glandular stomach included benign and malignant neuroendocrine tumors in the 150 and 300 mg/kg groups and females in the 75 mg/kg group. In all dosed groups of rats at all time points, the incidences of mucosal atrophy were significantly greater than in the vehicle controls. Neuroendocrine cell hyperplasia was observed in females at 6 months and males and females at 12 months and at 2 years. In core study female rats, there was a positive trend in the incidences of squamous cell papilloma or carcinoma (combined) of the forestomach, and the incidence in the 150 mg/kg group exceeded the historical control range. The incidences of renal tubule proliferative lesions in male rats were suggestive of a neoplastic effect in the kidney. Therefore, additional step sections of the kidneys of male rats were prepared. The incidences of renal tubule hyperplasia and adenoma in the extended evaluation and the combined incidences of standard and step sections in the 75, 150, and 300 mg/kg groups were greater than those in the vehicle controls. The incidences of nephropathy were increased in all dosed groups of females, and the increase was significant in the 300 mg/kg group. In dosed groups of male rats, there was a positive trend in the incidences of malignant mesothelioma, and the incidences were significantly greater in 150 and 300 mg/kg males than in the vehicle controls. The incidences of mammary gland fibroadenoma in 75 and 150 mg/kg males were significantly increased. The incidences of fibroma of the subcutaneous tissue in 37 and 75 mg/kg males and the combined incidences of fibroma or fibrosarcoma in 37, 75, and 150 mg/kg males were significantly increased. 2-YEAR STUDY IN MICE: Groups of 50 male and 50 female mice received methyleugenol in 0.5&percnt; methylcellulose by gavage at doses of 0, 37, 75, or 150 mg/kg for 105 weeks. Special study groups of 10 male and 10 female mice administered 37, 75, or 150 mg/kg were designated for toxicokinetic studies. Survival and Body Weights: Survival of all dosed groups of male mice was similar to that of the vehicle controls. Survival of dosed groups of females was significantly less. Mean body weights of dosed mice were generally less than those of the vehicle controls throughout the studies. Pathology Findings: Chemical-related increases in the incidences of liver neoplasms and nonneoplastic lesions in mice included hepatocellular adenoma and carcinoma, hepatoblastoma, hepatocholangiocarcinoma, eosinophilic foci, oval cell hyperplasia, bile duct hyperplasia, hemosiderin pigmentation, chronic active inflammation, and hematopoietic cell proliferation. In all dosed groups ofmales and females, the incidences of hepatocellular neoplasms and the multiplicity of neoplasms were generally greater than in the vehicle controls. The incidences of hepatoblastoma were significantly increased in all dosed groups of females and slightly increased in 150 mg/kg males. Hepatocholangiocarcinoma was observed in 150 mg/kg females. The incidences of eosinophilic foci, oval cell hyperplasia, portal hypertrophy, hepatocyte necrosis, hematopoietic cell proliferation, bile duct hyperplasia, and hemosiderin pigmentation were significantly increased in two or more dosed groups of male and/or female mice. The incidences of glandular ectasia, mucosal atrophy, chronic active inflammation, epithelial hyperplasia, and neuroendocrine cell hyperplasia of the glandular stomach were increased in one or more dosed groups of male and female mice. In addition, malignant neuroendocrine tumors were observed in the glandular stomach of two 150 mg/kg male mice; one male in this group had a carcinoma. TOXICOKINETIC STUDIES: Methyleugenol is rapidly absorbed following oral administration to rats and mice. The kinetic data are consistent with rapid clearance from the blood, metabolism in the liver, and excretion of the parent and various metabolites in the urine. GENETIC TOXICOLOGY: Methyleugenol was not mutagenic in S. typhimurium strain TA98, TA100, TA1535, or TA1537, with or without exogenous metabolic activation (S9). In cytogenetic tests with cultured Chinese hamster ovary cells, methyleugenol induced sister chromatid exchanges in the presence of S9, but no induction of chromosomal aberrations was noted in cultured Chinese hamster ovary cells following exposure to methyleugenol, with or without S9. In vivo, no increase in the frequency of micronucleated normochromatic erythrocytes was seen in male or female mice administered methyleugenol by gavage for 14 weeks. PHYSIOLOGICALLY BASED PHARMACOKINETIC MODEL: A physiologically based pharmacokinetic (PBPK) model resulting from intravenous and oral exposure was created to characterize tissue concentrations of methyleugenol in rats and mice. Data used to create the model were obtained from the literature or from current studies. The primary conclusions that can be reached from the PBPK model are: 1) absorption of oral doses of methyleugenol in rats and mice is rapid and complete, 2) distribution of methyleugenol to tissues is not hampered by capillary permeability, and 3) metabolism of methyleugenol is saturable and must have some extrahepatic component in the mouse. Model-based plasma methyleugenol concentrations were not found to be good dosimeters for evaluating neoplasm dose-response data. CONCLUSIONS: Under the conditions of these 2-year gavage studies, there was clear evidence of carcinogenic activity of methyleugenol in male and female F344/N rats based on the increased incidences of liver neoplasms and neuroendocrine tumors of the glandular stomach in male and female rats and the increased incidences of kidney neoplasms, malignant mesothelioma, mammary gland fibroadenoma, and subcutaneous fibroma and fibroma or fibrosarcoma (combined) in male rats. A marginal increase in the incidence of squamous cell neoplasms of the forestomach may have been related to methyleugenol administration in female rats. There was clear evidence of carcinogenic activity of methyleugenol in male and female B6C3F1 mice based on the increased incidences of liver neoplasms. Neuroendocrine tumors of the glandular stomach in male mice were also considered related to methyleugenol administration. In male and female rats and mice, methyleugenol administration caused significant increases in nonneoplastic lesions of the liver and glandular stomach.

We report the MR imaging findings of a primary malignant mesothelioma of the liver arising from Glisson's capsule. A 54-year-old woman, presenting with acute abdominal pain and a large liver mass previously shown on CT, underwent MR imaging to characterize the lesion. The tumor was a greater than 12 cm tumor located in the right lobe of the liver, which was sharply marginated, with heterogeneous internal signal, septations and central necrosis. The tumor was considered a hepatocellular carcinoma. The diagnosis of malignant mesothelioma was established by immunohistochemical staining and electron microscopy of the resected tumor.

Reported herein is a case of hepatocellular carcinoma (HCC) with unusual peritoneal dissemination masquerading as peritoneal mesothelioma. A 61-year-old man was clinically found to have multiple tumors in his abdominal cavity; peritonitis carcinomatosa was suspected. An autopsy revealed numerous tumors of various sizes in the abdominal serosa, omentum, and diaphragm. No signs of tumor, fibrosis, or cirrhosis were found in the liver, except for a small nodule in the hepatic triangular ligament. Histologically, the tumor cells proliferated in thick trabeculae or in sheets and formed a few canaliculi and tubules with homogenously brown contents in their lumina, which stained positively with Hall stain. Immunohistochemically, these tumors were positive for hepatocyte, alpha-fetoprotein (AFP) and low-molecular-weight cytokeratin; were focally positive for pan-cytokeratin and epithelial membrane antigen (EMA); and were negative for high-molecular-weight cytokeratin, vimentin, and calretinin. Carcinoembryonic antigen (CEA) produced a bile canalicular immunohistochemical staining pattern. Thus, the tumor was diagnosed as an HCC (Edmondson II type) of the triangular ligament with massive peritoneal dissemination. The origin of this tumor and its differential diagnosis (malignant mesothelioma, hepatoid adenocarcinoma, and hepatoid yolk sac tumor) are discussed.

This is the second of a two-part consideration of metastatic tumors to the ovary. Here, the matter is considered in 16 categories, largely site-specific. The first tumor discussed is gastric carcinoma of intestinal-type whose ovarian manifestations have been the subject of a recent paper which emphasized its differences from the Krukenberg tumor. Coverage of intestinal adenocarcinoma emphasizes the landmark 1987 paper of RH Lash and WR Hart. The section on pancreatic neoplasms reemphasizes the problems caused by metastatic ductal carcinoma, considered primarily in Part I, and discusses less common issues such as spread of neuroendocrine and acinar cell carcinomas. The limited information on spread of tumors of the gallbladder and extrahepatic bile ducts is then reviewed before more detailed consideration of hepatic neoplasms, prompted by recent contributions on hepatocellular carcinoma and intrahepatic cholangiocarcinoma, the latter based on significant experience with this problem in Thailand. The section on appendiceal neoplasms highlights ovarian spread of diverse tumors ranging from typical intestinal-type adenocarcinoma to signet-ring cell carcinomas with various patterns which in the ovary may prompt diagnoses such as a goblet cell (mucinous) carcinoid tumor, but whose ovarian features place them in the category of a Krukenberg tumor. The diverse problems in differential diagnosis of carcinoid tumor (provoked by nested, acinar, and other patterns, including folliclelike spaces) are then reviewed. The section on breast cancer emphasizes that, although usually a manifestation of late stage disease and often not bulky in the ovaries, metastatic breast cancer may form large masses which can represent the clinical presentation. That patients with breast cancer have an increased risk of primary ovarian cancer and that the latter is more common than secondary spread of breast cancer is noted. The section on lung tumors largely reflects information in a recent paper that small cell carcinoma and adenocarcinoma are the lung cancers that spread to the ovary most commonly. The extremely broad differential diagnosis posed by metastatic malignant melanoma ranging from that of an oxyphilic tumor, to a small cell tumor, to a follicle-forming neoplasm, is then considered. The sections on renal cell carcinoma and other urinary tract neoplasms emphasize the differential diagnosis of metastatic clear cell carcinoma and primary clear cell carcinoma, an issue usually resolvable by an awareness of the various features of the ovarian variant, rarely or never seen in the renal variant. The section on metastatic sarcomas discusses endometrial stromal sarcomas, gastrointestinal stromal neoplasms, and miscellaneous other sarcomas. The endometrial stromal tumors are problematic largely because the history of a primary tumor may be remote, in the ovaries the typical growth and vascular pattern of endometrial stromal neoplasms is not always conspicuous, and some endometrial stromal sarcomas in the ovary show sex cordlike patterns of growth. Recent information has indicated that gastrointestinal stromal tumors may rarely have significant ovarian manifestations and if the primary neoplasm is overlooked, the ovarian tumor may be misdiagnosed, usually as an ovarian fibromatous tumor, but potentially as another primary neoplasm. The sections on ovarian spread of uterine carcinomas emphasize the problems owing to cervical adenocarcinomas, which have a greater tendency to involve the ovaries than squamous cell carcinomas and can simulate primary mucinous or endometrioid cancers. The final neoplasms considered are malignant mesothelioma and the desmoplastic small round cell tumor. The microscopic features of malignant mesothelioma are so different from those of primary ovarian carcinoma in most instances that the diagnosis should be readily established on routine microscopic evaluation. The differential diagnosis of the desmoplastic small round cell tumor is more complex because of the greater overlap with the many other small cell malignant tumors that may involve the ovaries primarily or secondarily. Nonetheless, differences exist in most cases and awareness of the entity should lead to consideration of the desmoplastic neoplasm, particularly in a young female. In this area, as in a number of others considered in the review, immunohistochemistry may play a significant, sometimes crucial, role. However, as pointed out in brief concluding remarks, despite the aid of that modality, as in surgical pathology overall, careful consideration of the clinical background, distribution of disease, gross characteristics and spectrum of routine microscopic findings, will lead to the correct diagnosis in the majority of cases and at the very least lead to formulation of a considered differential diagnosis such that use of special techniques may be judicious and those results placed in context of the time-honored clinical and pathologic features.
