We evaluated the occurrence and type of malignant tumors in 148 patients with sarcoidosis followed at the Okayama University Hospital. Nine patients had malignancies; in 2 of 9 patients the development of malignancy preceded that of sarcoidosis, and one patient presented with sarcoidosis and malignancy at the same time. Six patients developed six types of malignancy following the development sarcoidosis; one case each of stomach cancer, lung cancer, breast cancer, thyroid cancer, testicular tumor, laryngeal cancer, and chronic lymphocytic leukemia. There was no significant difference between sexes (3 males and 3 females). The mean age of the cancer group at the onset of sarcoidosis was 56 years, which was significantly higher (p less than 0.05) than that of the control group. In these 6 patients, the mean interval from onset of sarcoidosis to detection of cancer was 11.7 years (range 1.5 to 30.2 years). The relative risk of malignancy was calculated based on the data for 148 patients with sarcoidosis with a total of 1371 person-years. The expected incidences of cancer for all sites and specific sites were estimated by applying age- and sex-adjusted person-years. The observed incidence of cancer was significantly (p less than 0.05) greater than the expected incidence for thyroid cancer, laryngeal cancer, and leukemia. No significant difference in incidence was found for all sites or for the other sites of cancer. The increased cancer incidence in sarcoidosis may be secondary to immunological abnormalities associated with this disease.

In some families breast cancer aggregates as the predominant site-specific neoplasia and in others in association with defined malignancies. In the case of familial adenocarcinomatous (Lynch II-syndrome) it occurs together mainly with colorectal and endometrial carcinoma whereas in the case of the Li-Fraumeni/SBLA-syndrome it belongs to a wider spectrum including sarcoma, brain tumors, lung and laryngeal cancer, leukaemia and adrenocortical carcinoma. The occurrence of these malignancies is reported as they were observed in the families of 600 women suffering from breast cancer.

HLA class I and II molecules play an important role in the immune system. Thus, alterations in their expression could affect the immunosurveillance against tumors. The expression of these molecules may therefore be one of the factors responsible for oncogenicity, due to their role as restriction elements in T cell recognition. A series of 78 primary laryngeal and 94 breast tumors were evaluated for the expression of MHC class I and II antigens, using monoclonal antibodies. We found a number of cases presenting total loss of HLA-ABC and selective losses of HLA-A and HLA-B antigens. These losses were statistically associated with clinical and pathological parameters such as T stage, degree of differentiation, scores according to the malignancy grading systems and degree of leukocytic infiltration. On the other hand, the de novo expression of DR antigens in laryngeal cancer was found in a group of neoplasms having a peculiar clinical behavior and excellent prognosis. Expression of class II molecules in breast tumors was also related to a better differentiation and prognosis. Thus, HLA class I and II antigen expression is closely related to aggressiveness and prognosis of laryngeal and breast cancer.

We have provided an in-depth, longitudinal, clinical/genetic/pathologic investigation of a family consonant with the sarcoma, breast cancer and brain tumors, lung and laryngeal cancer, leukemia, lymphoma, and adrenalcortical carcinoma syndrome. The pattern of cancer expression involves all three germinal layers with transmission through multiple generations. Segregation of these cancers occur in a manner consonant with an autosomal dominant mode of genetic transmission. It is hoped that recognition of the significance of this tumor pattern within families will provide an impetus for cancer surveillance, control, and laboratory research in the quest for clues to biomarkers which correlate with its cancer-prone genotype.

Cancer incidence trends from the late 1940s to 1983-84 were assessed among white residents of five geographic areas (Atlanta, Connecticut, Detroit, Iowa, San Francisco-Oakland) by means of data derived from several National Cancer Institute surveys, the Connecticut Tumor Registry, and the Surveillance, Epidemiology, and End Results Program. Incidence trends were compared with mortality trends for the entire United States and for the same five study areas. This study documented rising incidence and mortality rates for four cancers: lung cancer, melanoma of the skin, multiple myeloma, and non-Hodgkin's lymphomas. Increases in lung cancer continued through the early 1980s, but the rate of increase has been moderating during recent years, particularly among males and at younger ages for whom recent declines are evident. Overall, lung cancer incidence rates increased more than 220 and 400% among males and females, respectively. Although much rarer than lung cancer, melanoma of the skin and multiple myeloma increased greatly until the early 1980s among both males and females. The overall rate of increase in melanoma incidence among males was greater than that for lung cancer, and the rate of increase in multiple myeloma mortality among females was exceeded only by that for lung cancer. Increases of 70-120% were observed for non-Hodgkin's lymphomas. Increases in incidence and mortality rates for pancreatic cancer were apparent during the early years but less conspicuous in recent years. Laryngeal and kidney cancer rates generally increased substantially, although the changes were not remarkable for laryngeal cancer mortality among males and kidney cancer mortality among females. The rates for cancers of the mouth and pharynx increased among females but not males. Prostate, colon, and bladder cancer incidence rates increased more than 65% among males, whereas mortality rates changed only moderately. The incidence of thyroid cancer increased more than 75% among both sexes until the late 1970s, but mortality rates have declined during the period of study. Breast cancer incidence increased 30%, whereas mortality rates remained remarkably constant. The incidence of corpus uteri cancer increased dramatically during the mid-1970s and decreased substantially thereafter; these changes were not reflected in the mortality rates, which continually declined during the entire time period. The incidence of testicular cancer increased more than 90% and that of Hodgkin's disease did not change greatly; however, mortality rates for both cancers declined more than 50% since the late 1960s and early 1970s.(ABSTRACT TRUNCATED AT 400 WORDS)

A 10% increased risk of developing a second cancer was observed among approximately 36,000 persons reported to the Danish Cancer Registry with a cancer of the respiratory system during 1943-80. This estimate is markedly influenced by a striking tendency by physicians not to report or the Cancer Registry not to accept a report of a second lung cancer following a primary lung cancer (14 observed vs. 99 expected). A significant 30% excess of all second cancer was seen after laryngeal cancer (368 vs. 282), whereas the 22% excess following cancer of the nasal cavities and paranasal sinuses did not quite reach the level of statistical significance (95% CI = 0.9-1.6). For cancers of the lung and larynx, second cancers arose mainly in the buccal cavity, bladder, kidney (after lung cancer only) and lung (after laryngeal cancer only). These second cancers may be due to common carcinogenic factors, most likely tobacco. Elevated risks of second cancers of the breast, cervix uteri, and other female genital organs were found consistently. Radiotherapy may have contributed to the increased risk of breast cancer, but the excess risk of cancer of the female genital organs other than the cervix was unexpected. Although not significant, the risk of esophageal cancer following cancer of the larynx was below expectation (1 vs. 4.1), which was surprising because alcohol consumption and smoking are thought to be common risk factors for these 2 sites. Significant excesses of pancreatic cancer were observed following cancers of the lung, larynx, and nasal cavities, which might be due to more careful medical surveillance of these patients or to common risk factors such as cigarette smoking. Finally, the risk of a patient developing liver cancer after lung cancer was significantly elevated (22 vs. 11.6). This increase is unlikely to be due to misdiagnosed metastases from the lung, inasmuch as the risk was generally elevated throughout the observation period.

The aim of the present study was to verify whether the CMI response of the host's lymphocytes is directed towards tumor-associated antigens (TAA) specific for each histological type of tumor. The leucocyte migration inhibition (LMI) test was selected for this purpose, utilizing the cancer patients' leucocytes and, as neoplastic antigens, formalin-fixed cells of surgically removed cancer tissue. Two hundred and eighteen patients were studied, 110 of whom were affected by breast cancer, 48 by digestive tract and 60 by laryngeal cancer. The total amount of tests performed was 278. The leucocytes of 93 normal subjects were tested against the different tissues' cancer antigens, as were the leucocytes of 41 patients with cancer of different organs tested against the corresponding normal tissues' antigens. The breast cancer patients (122 tests performed) showed 82.35% positive tests against homologous antigen, 72.72% and 95.24% against heterologous (digestive tract and laryngeal cancer, respectively) antigens. The digestive tract cancer patients (69 tests performed) showed 70.27% positive tests against homologous, 66.66% and 43.48% against heterologous antigens (breast and laryngeal cancer respectively). The laryngeal cancer patients (87 tests performed) showed 74.29% positive tests against homologous, 38.10% and 80.65% against heterologous antigens (breast and digestive tract, respectively). The results led to the conclusion that the LMI test response of cancer patients was not "tissue specific": the test did not discriminate between the homologous and the heterologous cancer antigens, and it seems that the response was not directed towards specific TAA but only towards wide-range or "group" TAA, showed by several types of tumors.

A representative sample of 4657 adults greater than or equal to 45 years of age from the 5 main ethnic groups in Hawaii (Caucasians, Japanese, Chinese, Filipinos and Hawaiians) were interviewed during 1977-1979 regarding their diets. Quantitative food-consumption histories were obtained, from which average daily intakes of fat (saturated, unsaturated, cholesterol, meat, dairy, fish, animal, vegetable and total), protein (animal, meat, fish, dairy and total), carbohydrate, and vitamins A and C (including supplements) were calculated using food-consumption data from standard sources. Multiple regression analysis, with sex as a controlled variable, was used to assess the statistical relationship between these ethnic-sex-specific intakes and corresponding population-based cancer incidence rates of 15 selected sites for which nutrient components are suspected to be either causal or protective. Based on pre-set criteria for establishing important relationships, significant positive associations were found for 6 of the cancer sites: breast cancer with fat (saturated, unsaturated, animal, total) and protein (animal), corpus-uteri cancer with the same components as breast cancer, prostate cancer with fat (saturated, animal) and protein (animal, total), stomach cancer with fat (fish only) and protein (fish only), lung cancer with cholesterol, and laryngeal cancer with cholesterol. Breast and corpus-uteri cancers also showed significant negative associations with carbohydrate intake. The implications of these findings for future research are discussed.

Ninety seven patients with metastatic lung tumors were treated surgically in our department. Second pulmonary resections were performed in 13 patients. They consists of 9 males and 4 females, their age ranged from 12 to 75 years old (average 54.4 years old). Tumors originate from sarcoma in 5 cases, laryngeal cancer, colorectal cancer, renal cell cancer in 2 cases respectively, oral cavity cancer and transitional cell cancer in 1 case respectively. No second pulmonary resection was performed in patients with metastatic lung tumors originating from lung cancer or breast cancer, because they metastatize not only lung but also general organs. No second pulmonary resection was required in patients with testicular tumor and choriocarcinoma, because chemotherapy take good effect on them.

Data collected by the Cancer Registry of the Swiss Canton of Vaud (whose population in 1980 was about 530,000 inhabitants) were used to estimate the incidence of second metachronous primary cancers following any specific neoplasm. Among 34,615 cases of incident neoplasms registered between 1974 and 1989 and followed through integrated active follow-up to the end of 1989, for a total of 118,241 person-years at risk, there were 2,185 second primaries (1,280 males, 905 females). For both sexes, the standardised incidence ratios (SIR) were significantly elevated by about 20%. Overall significantly elevated ratios were registered for cancers of the oral cavity and pharynx (SIR = 1.6 for males, 2.0 for females), oesophagus in males (SIR = 1.5), lung in males (SIR = 1.4), skin melanoma (SIR = 1.7 for males, 1.5 for females), non-melanomatous skin cancers (SIR = 1.6 for males, 1.5 for females), female breast (SIR = 1.3), kidney (SIR = 1.5 for males, 1.9 for females), and thyroid in males (SIR = 2.4). When specific first cancer sites were considered, the SIR following a cancer of the oral cavity and pharynx was around 3 in both sexes, mainly on account of a substantial excess of second primaries of the oral cavity, oesophagus, larynx and lung. The overall SIR following laryngeal cancer was 3.0, and significant excesses were observed for oral cavity and pharynx, oesophagus and lung. After lung cancer, the overall SIR was 1.7 for males and 2.6 for females, and significantly elevated SIRs were observed for oral cavity, lung and oesophagus. Following non-melanomatous skin cancers, elevated SIRs were observed in both sexes for skin melanoma and non-melanomas. The incidence of any cancer after breast cancer was significantly elevated (SIR = 1.2), mainly on account of an elevated risk of subsequent breast cancer (SIR = 1.7). With reference to cervical cancer, there was a significant excess for any subsequent primary (SIR = 1.6), and for lung cancer (SIR = 7.8). Significantly elevated SIRs were observed for kidney following bladder cancer, and for bladder after kidney cancer. In both sexes, the incidence of cancers of any site was elevated following leukaemias (SIR = 1.7 for males, 2.5 for females), and a significant excess was registered for lung in males and non-melanomatous skin cancers in both sexes.(ABSTRACT TRUNCATED AT 400 WORDS)
