Guanosine 3'5'-cyclic monophosphate (cGMP) in the plasma of normal persons and patients with lung or breast cancer and other kinds of neoplasma or other diseases was determined using radioimmunoassay. In comparison with normal persons, significant elevation occurred in the cGMP in the plasma of patients with various kinds of cancer or renal insufficiency. The average cGMP values in the plasma of eight normal persons, 16 patients with lung cancer, 16 patients with breast cancer, five patients with oesophagus cancer, three patients with liver cancer, three patients with stomach cancer, ten patients with renal insufficiency and two patients with myocardial infarction, were respectively 3.46, 9.05, 5.39, 5.42, 7.33, 11.66, 19.55, and 8.0 pmol per ml of plasma. There was no elevation in the cGMP in the plasma of the patients with other diseases studied.

A retrospective mortality study has been carried out on workers employed in the manufacture of chlordane and heptachlor between 1946 and 1976. The study group was comprised of 1403 white males who worked for more than three months at either of the two plants in the United States now producing these compounds. Information on deaths among terminated employees was obtained from the Social Security Administration and supplemented by information collected by another investigator by individual follow-up. There were 113 deaths observed in the group, compared to 157 expected, giving a standardized mortality ratio (SMR) of 72. There was no overall excess of deaths from cancer, even among workers followed twenty or more years after entry into the occupation. There was one death from liver cancer. An excess of deaths from lung cancer (12 observed, 9.0 expected) was not statistically significant and was not distributed by duration of exposure or of latency in any pattern suggesting an etiologic role for chlordane-heptachlor exposure. Although diseases of the circulatory system as a whole showed fewer deaths than expected (SMR 83), there was a statistically significant excess of deaths from cerebrovascular disease (17 observed, 9.3 expected). This excess was not related to duration of exposure or latency and occurred exclusively after termination of employment.

201TI was used as an imaging agent in 173 malignant tumors and 76 benign lesions. The sensitivity, specificity, and accuracy were 0.64, 0.61, and 0.63, respectively. Sensitivity was good in thyroid cancer (0.91) and fair in primary lung cancer (0.70) and primary liver cancer (0.71). Compared with 67Ga, 201TI appears to have a higher sensitivity in thyroid cancer and nearly the same sensitivity in primary lung cancer. 201TI might be useful in distinguishing cold thyroid nodules and in differentiating primary liver cancer from metastases.

Serum RNase (ribonuclease) of normal persons and of patients with pancreatitis, carcinoma of pancreas, or other neoplasms was determined with poly(C) as substrate. Strikingly abnormal elevations occur in the serum RNase of patients with pancreatic cancer. There is no elevation in the serum RNase level of patients with pancreatitis. Average serum RNase values of 52 normal persons, 10 patients with pancreatitis, 30 patients with pancreatic cancer, 28 patients with breast cancer, 11 patients with lung cancer, 20 patients with colon cancer, six patients with stomach cancer, and four patients with liver cancer, respectively, were 104, 120, 383, 131, 173, 197, 194, and 152 units/ml of serum. Ninety percent of the patients with pancreatic cancer were above the level of 250 units of serum and 90% of all patients with varied cancers were below this level. In the presence of severe renal insufficiency, marked elevation of serum RNase was also observed. Serum RNase, because of its unique specificity, pancreatic origin, and its abnormal elevation in sera of patients with pancreatic cancer, serves as a reliable biochemical marker of carcinoma of the pancreas in the presence of normal renal function.

Multiforms of aminopeptidases and arylamidases in normal human liver, stomach, lung, ileum, colon, rectum, and kidney, and cancer tissue from human liver, stomach, and lung were separated by triethylaminoethyl cellulose column chromatography. The aminopeptidases and arylamidases were solubilized from human tissues by treatment with bromelain, and their column chromatograms on triethylaminoethyl-cellulose gave different patterns of multiforms of enzymes in these tissues. The fractions of enzymes separated specificities toward L-leucyl-beta-naphthylamide, L-leucinamide, L-methioninamide, L-phenylalaninamide, and L-alaninamide. The activity of aminopeptidase toward L-leucinamide and of arylamidase toward L-leucyl-beta-naphthylamide was higher in human stomach cancer tissue and lower in hepatic cancer tissue than in normal stomach and liver, respectively. In lung cancer tissue, the activity of aminopeptidase toward L-leucinamide was abnormally low, while the activity of arylamidase toward L-leucyl-beta-napthylamide was similar to that in normal lung. The substrate specificities or patterns of the multiforms of these enzymes in cancer tissue from human liver, stomach, and lung were shown to differ from those of normal liver, stomach, and lung, respectively, by triethylaminoethyl cellulose column chromatography.

Adriamycin is a new anticancer antibiotic with a wide spectrum of activity against solid tumours. The results obtained with this agent in 159 patients with histologically confirmed advanced metastastic malignancies are reported. Encouraging results were obtained in patients with sarcomas of bone and soft tissue (12/22). Response was also seen in mesothelioma (3/9) and lung cancer (5/15). A variety of other neoplasms was also treated and results obtained in neuroblastoma, testicular tumours, stomach carcinoma, breast cancer and nephroblastoma are reported. Treatment is discussed, with reference to response rates and toxicity. Results in 72 patients with advanced breast cancer, who received adriamycin in combination with other chemotherapeutic agents, are presented. Seventeen patients with primary liver cancer were also treated with adriamycin. To date, this is the only chemotherapeutic agent that appears to significantly improve survival times in patients with this resistant form of cancer. The prophylactic use of adriamycin against osteogenic sarcoma is also discussed.

In order to compare risk of various internal organ cancers induced by ingested inorganic arsenic and to assess the differences in risk between males and females, cancer potency indices were calculated using mortality rates among residents in an endemic area of chronic arsenicism on the southwest coast of Taiwan, and the Armitage-Doll multistage model. Based on a total of 898,806 person-years as well as 202 liver cancer, 304 lung cancer, 202 bladder cancer and 64 kidney cancer deaths, a significant dose-response relationship was observed between arsenic level in drinking water and mortality of the cancers. The potency index of developing cancer of the liver, lung, bladder and kidney due to an intake of 10 micrograms kg day of arsenic was estimated as 4.3 x 10(-3), 1.2 x 10(-2), 1.2 x 10(-2), and 4.2 x 10(-3), respectively, for males; as well as 3.6 x 10(-3), 1.3 x 10(-2), 1.7 x 10(-2), and 4.8 x 10(-3), respectively, for females in the study area. The multiplicity of inorganic arsenic-induced carcinogenicity without showing any organotropism deserves further investigation.

Cancer mortality during 1970-85 of immigrants from East and West Africa and the Caribbean to England and Wales is described. Overall cancer mortality was raised in West African males (RR 1.38, 95% CI 1.25-1.54), and non-significantly raised in West African females (RR 1.14, 0.96-1.37) compared to mortality in the England and Wales-born population. Much of the increased risk was due to very high rates of liver cancer in males (RR 31.6, 23.8-41.9), but rates were also raised for a wide range of other cancers in each sex. Only lung and brain cancer had significantly decreased mortality. In East Africans, overall cancer mortality was low in males (RR 0.63, 0.56-0.70), and in females (RR 0.80, 0.72-0.89). Mortality was significantly low for cancers of the stomach, pancreas and testis, and Hodgkin's disease in males, for cervical cancer in females, and for lung cancer and melanoma in both sexes. Cancer sites with significantly raised mortality included oropharyngeal cancer, leukaemia, and multiple myeloma in both sexes. In Caribbean immigrants overall cancer rates were significantly low in males (RR 0.71, 0.68-0.74) and in females (RR 0.76, 0.73-0.80). Mortality was significantly low for many cancers including colorectal, lung, testis and brain cancers. Mortality was significantly raised only for cancer of the prostate in males, of the placenta in females, and of the liver, non-Hodgkin's lymphoma and multiple myeloma in both sexes. Overall, mortality was high from prostatic cancer and liver cancer, and was low from brain cancer, in predominantly ethnic African immigrant groups. Both East and West African immigrants had raised rates of leukaemia. All of the migrant groups had high rates of multiple myeloma and low rates of testicular, ovarian and lung cancer. Genetic and environmental factors that may contribute to these patterns are discussed.

An enzyme-linked immunosorbent assay method for serodiagnosis of cancers was developed by employing histone H2B. This method measures anti-histone H2B antibody levels in sera and includes a device for coating the plastic immunoplate with a mixture of histone H2B and diluted fetal calf serum. The coating of immunoplates with this mixture decreased apparent sensitivity of the assay compared with that in the absence of fetal calf serum, but effective reduction of nonspecific background enabled a specific assay of anti-histone H2B antibody with excellent reproducibility. By this method cancer patients were discriminated from normal healthy subjects at detection rates of 37% for lung cancer, 33% for liver cancer, 50% for pancreatic cancer, 42% for colon cancer, and 78% for cervical cancer. However, stomach and esophagus cancers showed detection rates of less than 17%, which are comparable to the values for benign diseases. It is likely that this assay method detects squamous cell carcinomas at relatively high rates.

Experimental and epidemiological studies of risk factors for hepatocellular carcinoma (HCC): cirrhosis, male sex, oral contraceptives, alcohol, smoking, and aflatoxins, are evaluated, with meta-analysis for oral contraceptives, alcohol, and smoking. It is likely that an initiating event and one or more promoting events interact, probably with prolonged inflammation, necrosis and regeneration, to cause cancer in several types of cirrhosis. Over 90% of HCC patients have cirrhosis, usually from hepatitis B virus. The viral post-necrotic liver is often chronically dysplastic, but other types of cirrhosis are associated with HCC if they endure long enough. The proportion of men with HCC increases as hepatitis progressors to cirrhosis and then to HCC. Meta-analyses of 3 oral contraceptive studies resulted in a risk of 2.8 for 8 years of use, but 9.9 for 8 years. Population studies do not show any concentration of HCC in countries with high pill use, so the rarity of this cancer may have biased the results. Large epidemiologic studies are needed to refine risk estimates for oral contraceptives and HCC. Alcohol abuse of 80 g/day gives a risk of about 1.65 in pooled studies, compared to a risk of 1.1 for 80 g/day. Smoking gives a risk of 1.9, but there is no evidence for a secular trend by country in proportion to dose, as is evident for lung cancer. There is good experimental evidence that aflatoxin acts as an initiator for liver cancer, but there is not practical way to judge exposure for clinical studies.
