The risk of developing a second primary cancer was evaluated in approximately 19,000 persons with initial cancers of the lymphatic and hematopoietic system in Connecticut between 1935 and 1982. Significant excesses for all second cancers were observed among patients with leukemia (34%), Hodgkin's disease (70%), non-Hodgkin's lymphoma (25%), and multiple myeloma (24%). In general, the risk of second cancers was greater in males than in females, even for cohorts not showing an excess of surveillance-related prostate cancer. Among patients with leukemia, significant excesses of cancers of the lung, kidney/ureter, and prostate were noted; cutaneous melanoma was elevated only in males. These excesses did not persist in the small number of long-term survivors. Possible etiologic factors included tobacco smoking for lung and kidney cancers, medical surveillance artifact for prostate cancer, and immunosuppression for malignant melanoma and lung cancer. The large number and good prognoses of patients with chronic lymphocytic leukemia strongly influenced the pattern of second cancers when all leukemias were analyzed together; no evidence was found for an increased risk of second cancer in patients with acute lymphocytic leukemia. A disproportionate number of subsequent cancers, particularly those of the kidney and ureter, were diagnosed incidentally at autopsy. Patients with Hodgkin's disease displayed significant excesses of cancers of the buccal cavity and pharynx, lung, female breast, and thyroid. The latter 3 sites remained significantly elevated in long-term survivors (10 yr or more postdiagnosis), so that radiation therapy may have contributed to their development. Among persons with non-Hodgkin's lymphoma, cancers of the stomach, lung, brain, and connective tissue occurred excessively. The first 3 sites, plus cancers of the urinary bladder, remained elevated among long-term survivors. The brain cancer excess, not previously reported, may represent misclassification of central nervous system lymphoma. The risk of gastric cancer is reminiscent of similar findings in patients with both acquired and genetically determined immunodeficiency disorders. The alkylating agent, cyclophosphamide, used extensively in the treatment of non-Hodgkin's lymphoma, is known to cause bladder cancer in man.(ABSTRACT TRUNCATED AT 400 WORDS)

Among 4,184 patients with cancer of the esophagus, 55 second primary cancers were observed, whereas 64 were expected [relative risk (RR) = 0.86]. The absence of an excess risk of alcohol- and tobacco-related cancers was not anticipated. A significant 19% deficit of second cancers was found among 30,843 patients with stomach cancer. Cancer of the rectum, kidney, and lung all occurred significantly below expectation. An excess risk of ovarian cancer (RR = 1.9) was seen in women. Reasons for these findings are not entirely clear. Cancer of the small intestine is rare, and despite a relatively short survival expectation, a moderate excess of second cancers was seen among 868 patients (36 vs. 26.8). Only cancers of the liver and gallbladder were significantly elevated, and the possibility of misclassified metastases is discussed. Colon cancer is one of the most common cancers in Denmark, and 29,490 patients with this disease were at slightly lower risk for development of second cancer (RR = 0.96; 95% confidence interval = 0.9-1.0) than the general Danish population, excluding secondary colon cancers. Esophageal, stomach, and liver cancers occurred less frequently than expected. That cancers of the uterine corpus and ovary were significantly increased supports the notion that common risk factors, such as diet and endogenous hormones, influence the development of these cancers. A significant 23% deficit of second cancers was also found among 26,597 patients with cancer of the rectum, excluding secondary rectal cancer. Significant deficits were seen for cancers of the stomach (RR = 0.5), lung (RR = 0.8), and brain (RR = 0.5), and for multiple myeloma (RR = 0.4). The likelihood of underreporting of second cancers, especially of the digestive system, is discussed. However, cancer of sites previously reported to be associated with rectal cancer, e.g., the colon, breast, and uterus, did not occur below expectation. Cancers of the liver and biliary tract occurred in 4,453 patients; their average survival was only 1 year. Except for a slight excess of cancer of the ovary (5 vs. 1.6), the risk of second cancer development for all sites was consistent with unity (RR = 0.90). The risk of second cancers among 7,752 persons with cancer of the pancreas was not greater than expected (88 vs. 85.2). Males were at significant risk of kidney cancer (RR = 3.2), whereas females showed elevated rates of cancers of the uterine corpus (RR = 3.2) and ovary (RR = 3.1). No site occurred significantly below expectation.

A clinical study on human lymphoblastoid interferon (HLBI) in various advanced malignant diseases was performed. HLBI was administered to a total of 25 patients with various advanced malignant diseases in order ot investigate antitumor effect and toxicity. The diseases evaluated were as follows: 8 multiple myeloma (MM), 2 chronic lymphocytic leukemia (CLL), 2 adult T cell leukemia (ATL), 1 acute lymphocytic leukemia (ALL), 8 breast cancer, 3 gastric cancer and 1 ovarian cancer. Twenty-three patients received either 3 million or 6 million units of HLBI by daily intramuscular injection or every other day. One patient with ATL received 18 million units of HLBI by i. v. daily and 1 patient with ALL received 30.32 million units of HLBI i. v. daily. Tumor regression (PR) was observed in 2 patients with MM, each one patient with ATL and ALL, respectively. Major toxicities were pyrexia, myelosuppression, general malaise and G.I. toxicity. Several patients showed abnormality of hepatic or renal function. Two patients who received HLBI for more than a year developed cardiac toxicity.

Death certificate analyses of white male Iowans over age 30 who died of multiple myeloma, non-Hodgkin's lymphoma, prostate cancer or stomach cancer between 1964 and 1978 were completed. Each case was matched to two controls on age (within two years) at death, county of residence, and year of death. Consideration of usual occupation, as recorded on the death certificate, resulted in the following odds ratios for mortality due to the specified cancers among farmers: multiple myeloma, 1.48; non-Hodgkin's lymphoma, 1.26; prostate cancer, 1.19; and stomach cancer, 1.32. Each is statistically significant (p less than 0.05). Odds ratios were computed separately for three birth cohorts according to counties stratified by crop and livestock production. Multiple myeloma was elevated in those born after 1890 and was associated with number of egg-laying chickens, hog production, insecticide use, and herbicide use. Non-Hodgkin's lymphoma was elevated in those born before 1901 and was associated with egg-laying chickens, milk products sold, hog production, and herbicide use. Although prostate cancer was elevated in those born before 1901, it was not associated with any agricultural practice. Stomach cancer was elevated in each birth cohort. It was associated with milk products sold, cattle production, and corn per acre.

The cause-specific mortality experience of 2,509 active and retired members of the Oil, Chemical, and Atomic Workers International Union (OCAW) who worked at three oil refineries in the Beaumont/Port Arthur area of Texas was examined to determine whether there might be unusual patterns of fatal disease related to workplace exposures. Deaths that occurred between 1943 and 1979 were identified from membership records of the OCAW headquarters in Denver and from the records of union locals in Texas which represent workers at the three refineries. Death certificates were obtained from state vital records offices for the decedents. Cause-specific Proportionate Mortality Ratios (PMRs) were calculated using the mortality experience of the U.S. general population as a standard. Excess mortality from stomach cancer occurred among active union members who worked at Refinery A and among active and retired members who worked at Refineries B and C. PMRs for leukemia, multiple myeloma, and other lymphomas were elevated, especially among retired workers. Relative frequencies of brain tumor deaths were significantly elevated among active members at all three refineries and slightly elevated among retirees at Refineries A and C. Findings suggest that oil refinery workers may have elevated risks of these cancers and indicate that more definitive studies are necessary.

Human fibroblast interferon(HFIF) was used in 26 patients with various malignant diseases, most of whom had previous chemotherapy. The dosages used were 3 X 10(6) IU or 6 X 10(6) IU of HFIF i. v. daily. Out of 24 evaluable patients, there were 2 partial remissions (CLL 1 and multiple myeloma 1), and 7 stable diseases (multiple myeloma 2, stomach cancer 2, non-Hodgkin's lymphoma 1, CLL 1 and malignant melanoma 1). The majority of the patients experienced fever exceeding 38 degrees C and chills, which became uncommon within several days of treatment. Other side effects included myelosuppression, general malaise, anorexia, hepatic dysfunction and renal dysfunction, which were mild and tolerable.

The cause-specific mortality experience of 3,105 members of the Oil, Chemical and Atomic Workers International Union was examined to determine if there were unusual patterns of fatal disease that may be indicative of hazardous agents in the work environment. Deaths among active Union members that were reported by locals in Texas between 1947 and 1977 were identified through membership records, and proportionate mortality was analyzed in several broad industrial categories. PMRs for cancers of the liver and biliary passages, pancreas, lung and skin were elevated among refinery and petrochemical plant workers; however, risks did not increase with length of membership. Increased relative frequencies of stomach cancer, cancer of the brain, leukemia and multiple myeloma were confined to white males in the same category who had been Union members for 10 or more years. Excess deaths from stomach cancer and brain cancer were found among white male members employed at one specific oil refinery and petrochemical plant. Observed numbers of deaths from cancer of the stomach were greater than expected among whites and nonwhites, and an elevated PMR for lung cancer among nonwhites was found at an additional plant. Findings suggest that workers in this industry may be at increased risk of certain cancers and indicate areas for further investigation.

Risk of cancer mortality from 1973 to 1985 in persons born in the Indian subcontinent who migrated to England and Wales was analysed by ethnicity, and compared with cancer mortality in the England and Wales native population, using data from England and Wales death certificates. There were substantial highly significant raised risks in Indian ethnic migrants for cancers of the mouth and pharynx, gall bladder, and liver in each sex, larynx and thyroid in males, and oesophagus in females. There were also substantial raised risks in these migrants of each sex for non-Hodgkin's lymphoma and myeloma. For the mouth and pharynx, and liver in each sex, and gall bladder in females, there were also raised risks of lesser magnitude in British ethnic migrants. For colon and rectal cancer and cutaneous melanoma in each sex, ovarian cancer in women and bladder cancer in men, there were appreciable significantly reduced risks in the Indian ethnic migrants not shared by those of British ethnicity. Appreciable raised risks in British ethnic migrants not shared by those of Indian ethnicity occurred for nasopharyngeal cancer in males, soft tissue malignancy in both sexes and non-melanoma skin cancer in males. In migrants of both ethnicities there were appreciable significantly raised risks in each sex for leukaemia and decreased risks in each sex for gastric cancer, for lung cancer except in females of British ethnicity and in males for testicular cancer. The results suggest the need for public health measures to combat the high risks of oral and pharyngeal cancers and liver cancer in the Indian ethnic immigrant population of England and Wales, by prevention of betel quid chewing and hepatitis transmission respectively. The data also imply that early exposures or early acquired behaviours in India, or exposures during migration, may increase the risk of leukaemia and reduce the risks of gastric and testicular cancers in the migrants irrespective of their ethnicity. Aetiological studies would be worthwhile to investigate the reasons for the sizeable decreased risk of colon and rectal cancer and increased risk of gall bladder cancer in each sex and the increased risk of thyroid and laryngeal cancer in males and oesophageal cancer in females of Indian ethnicity but not of British ethnicity who have migrated from the Indian subcontinent.

We have conducted a cohort study of cancer risks among 140,208 Swedish farmers in order to compare their cancer risks with those of the general male population. Since there were no individual data regarding exposure to agricultural chemicals and acquiring such data was not realistic, we obtained crude and hypothetical estimates for exposure by dividing the data into time periods, year-of-birth cohorts and geographical areas. The cohort was followed-up in the Cancer Environment Register from 1 January 1971 either until death or until 31 December 1987. The relative risk was computed as the ratio of the observed and expected number of cases (SIR = standardized incidence ratio). A total of 15,040 cases were observed vs 18,918 expected, resulting in a statistically significant decreased SIR of 0.80 (95% confidence interval: 0.78-0.81). The SIR was significantly decreased for several cancer sites, and the lowest value was found for tongue, lung, oesophagus, liver and urinary organs, which is in agreement with other studies on cancer risks among farmers. Other major cancer sites with decreased SIRs were the colon, rectum, pancreas and kidney. Lip cancer and multiple myeloma showed statistically significant increased risks. SIRs for stomach cancer, prostate cancer, skin carcinoma, malignant melanoma, tumours in connective tissue or muscle, malignant lymphomas and leukaemia were all close to unity, which is not consistent with several other studies that have shown increased risks for these sites. For malignant lymphomas the SIR increased over time, though not significantly, and was highest among younger farmers. The SIR for non-Hodgkin lymphoma was lowest in the northernmost region. This gives some support to the hypothesis that there is an association between non-Hodgkin lymphoma and exposure to pesticides and other agricultural chemicals. It is of note that the SIR for multiple myeloma was significantly increased in those parts of Sweden where the use of pesticides has been less frequent and in lower amounts.

The risk of cancer was evaluated among 77,952 asthma patients with bronchial asthma. The series was obtained through linkage of two registers: the Finnish Social Insurance Institution's file of asthma patients and the Finnish Cancer Registry. There was a significant excess risk of lung cancer in both sexes, the standardized incidence ratio (SIR) being 1.32 among men and 1.66 among women. In women, the risk of cancer of the rectum was significantly increased (SIR 1.42), whereas the risks of cancer of the corpus uteri and multiple myeloma were lower than expected (SIR 0.76 and 0.53, respectively). In men, the incidence of cancer of the larynx was significantly reduced (SIR 0.63) and that of the bladder increased (SIR 1.25). When both sexes were combined, cancers of the colon (SIR 1.17) and rectum (SIR 1.28) also showed a significantly elevated risk. A reduction in risk was seen in stomach cancer (SIR 0.88) and lymphatic leukaemia (SIR 0.55). The increased lung cancer risk may be due to local inflammatory changes. It is possible that differences in the immune system, e.g. natural killer cell activity, explain some of the reduced cancer risks.
