Carcinoma of the prostate is today one of the three most frequent causes of death from neoplastic disease in men in the United States (G4). The early studies of Gutman and his associates (Gil, G12, R6, S30) established that serum acid phosphatase activity was elevated very frequently in patients with metastatic carcinoma of the prostate. It is of interest to consider briefly the uncertainties inherent in the development of this relationship. Skeletal metastases, if sufficiently large, are of course detectable by roentgenographic examination, but smaller ones may not be, and metastases to soft tissues may likewise be undetectable. For example, in 15 cases of metastazing carcinoma reported by Gutman...

A 65-year-old man with a history of bilateral ureterohydronephrosis with chronic renal insufficiency, hyperuricemia, and bladder carcinoma reported a 2-month history of prurigi-nous lesions on his trunk and limbs. His medications included long-term allopurinol and calcium, and furosemide (dose not stated), which he had taken for 4 months. The diagnosis was confirmed on skin biopsy. One year after stopping furosemide, his lesions were still present but had become less symptomatic. 

A comprehensive study of the tolerance of laboratory animals to vapors of 2-nitropropane was reported in 1952 (100). In a study pubHshed in 1979, rabbits and rats survived exposure to nitromethane for six months at 750 and 100 ppm, respectively, with no unexpected findings (101). Similarly, no compound-related effects were found for rabbits exposed to 2-nitropropane at 200 ppm or for rabbits or rats exposed at 27 ppm. Liver damage was extensive in male rats exposed at 207 ppm for six months, and hepatocellular carcinomas were observed. Subsequendy, the International Agency for Research on Cancer (lARC) found that there is "sufficient evidence" to conclude that 2-nitropropane causes cancer in rats but that epidemiologic data are inadequate to reinforce the conclusion in humans (102). The National Toxicology Program also concluded that it "may reasonably be anticipated to be a carcinogen" (103). 

In an animal study of rats exposed by inhalation to ethylene oxide at 10, 33, or 100 ppm for approximately two years (245), and in a separate chronic rat study in which rats were exposed to 50 or 100 ppm of ethylene oxide (240), increased incidences of mononuclear cell leukemia, peritoneal mesothelioma, and various brain tumors have been reported. In an NTP (246) two-year inhalation study of mice at 50 and 100 ppm, alveolar/bronchiolar carcinomas and adenomas, papillary cystadenomas of the harderian gland, and malignant lymphomas, uterine adenocarcinomas, and mammary gland tumors were increased in one or both exposure groups. 

An elevated activity of serum acid 3-glycerophosphatase was not specific for carcinoma, as Marshall and Amdor found it in 8% of patients with uncomplicated prostatic hyperplasia, in some patients with bone fractures, carcinoma involving the liver, and other diseases of bone and liver. This activity has also been reported to be elevated in 3 of 12 patients with Gaucher s disease. 

The liver is an organ that shows variable effects from trichloroethylene among species, and this can probably be attributed to interspecies differences in metabolism (see Section 2.4.2.1). Specifically, the apparent difference in susceptibility to trichloroethylene-induced hepatocellular carcinoma between humans and rodents may be due to metabolic differences (see Section 2.4.2.3). Kidney effects are also variable among species. Humans and mice are less sensitive than rats. In rats exposed chronically to trichloroethylene, toxic nephrosis characterized as cytomegaly has been reported (NTP 1988). The kidney effects in rats do not seem to be related to an increase in alpha-2 -globulin (Goldsworthy et al. 1988). Effects on the nervous system appear to be widespread among species, presumably due to interactions between trichloroethylene and neuronal membranes. 

Carcinogenicity of NDELA. Our special interest in NDELA as a constituent of tobacco products and as an environmental agent relates to the observation that this nitrosamine induces carcinoma of the liver as well as of the kidney in rats (21,22) and carcinoma of the nasal cavity and papillomas of the trachea in hamsters (23). Recently, Lijinsky reported that NDELA admini-... 

In culture, the human colon carcinoma cell hne Caco-2 spontaneously differentiates at confluency into polarized cells with enterocyte-like characteristics. The principle of this approach consists of following the passage of the compound of interest from the apical or lumen-like sides to the basolateral or lymph-hke sides of Caco-2 cells, thus following the absorption of the compound per se. One obhgate step for fat-soluble nutrients such as carotenoids to cross the intestinal barrier is their incorporation into CMs assembled in the enterocytes. Under normal cell culture conditions, Caco-2 cells are unable to form CMs. When supplemented with taurocholate and oleic acid, Caco-2 cells were reported to assemble and secrete CMs. ... 

Data about curcunfin encapsulated in liposomes have been reported recently. The authors encapsulated curcumin into a liposomal delivery system in order to study the in vitro and in vivo effects of this compound on proliferation, apoptosis, signaling, and angiogenesis using human pancreatic carcinoma cells. Carotenoids of different polarities and in competition with cholesterol were specifically incorporated into liposomes in order to mimic the physiological uptake by cells and monitor their antioxidant capacities. ... 

Generally, a CA 15-3 cutoff of 25 U/ml is used to detect stage I breast cancer. In higher stages, the sensitivity is reported to be much better, which makes it a good test of tumor burden. CA 15-3 is reported to be elevated in other disease conditions such as liver disease (particularly chronic hepatitis, cirrhosis, and carcinoma), some inflammatory conditions (sarcoidosis, tuberculosis, systemic erythematosus), and other carcinoma (lung and ovary). For this reason, positive CA 15-3 results should be interpreted with caution (20,21). 

CA 125 is a mucin-like glycoprotein antigenic determinant expressed on the surface of coelomic epithelium and human ovarian carcinoma cells however, it does not appear to be specific for ovarian cancer because elevated levels have been reported in breast and colorectal cancers. Studies have shown increased CA 125 levels in patients with ovarian cancer, whereas decreased CA 125 levels in chemotherapy are associated with improved possibility for survival. Some studies have shown failure of CA 125 levels to return to normal after chemotherapy, indicating...
