For the studies of the esophageal lymphatics, endoscopic RI-lymphoscintigraphy was performed in 23 cases of esophageal cancer, 3 cases of lung cancer and 5 cases of gastric cancer. 99mTc-Rhenium colloid was endoscopically injected into the submucosal layer of the esophagus near the tumor and the images of the lymph flow were obtained after about 3 hours. Single photon emission computerized tomography (SPECT) was used to acquire the three-dimensional images of the esophageal lymph flow on 19 patients. RI-uptake of all dissected lymph nodes was also counted after the operation. The results were shown as follows. 1. Whole neck, thoracic and abdominal lymph nodes could be imaged in any cases injected at any parts of the thoracic esophagus. But the lymph flow in the upper third of the esophagus tended to move mainly upward, and the lymph flow in the lower third tended to move mainly downward. 2. The block of intra-mural lymph vessels by the tumor had very important roles upon the esophageal lymph flow. 3. The removal of upper mediastinal lymph nodes and intraabdominal lymph nodes as well as paraesophageal lymph nodes seemed to be very important for curative resection of carcinoma of the esophagus.

The role of nutrients in cancer causation has been a subject of considerable interest, research, and public discussion in recent years. Results from epidemiologic, clinical, and animal studies have suggested that: 1) a reduction in total calories decreases risk for a number of tumor types; 2) dietary protein is directly correlated with liver, prostate, and colon cancer, among others, with increasing dietary protein increasing the risk; 3) increased dietary fat is correlated with increased risk for breast cancer; the evidence for an effect of fat on colon cancer is equivocal in human and animal studies; 4) a deficiency of vitamin A may enhance lung and colon tumors in animal experiments but in human this is equivocal. Increasing vitamin A above normal levels, as an anticarcinogenic effect, has not been satisfactorily demonstrated in animal models. The synthetic retinoid, 13-cis retinoic acid, inhibits both colon and lung cancer in animal models; 5) zinc deficiency is associated with enhanced esophageal cancer in humans and markedly enhances animal tumors; selenium inhibits this form of neoplasia in animals, 6) diets low in lipotropes enhance liver cancer induced by a variety of hepatocarcinogens. Our data from studies in animal models agree in some cases with epidemiological observations, but disagree with others, particularly fat and colon cancer. Overall, some forms of cancer are enhanced by excessive calories, increased dietary protein and fat, and by deficiencies of vitamin A, selenium, zinc, and lipotropes. Decreasing total intake of calories, protein, and fat, and ensuring adequate dietary levels of vitamin A, selenium, zinc, and lipotropes decreases risk for some forms of cancer.

Over the last decades, the relationship between tobacco smoking and cancer has been studied utilizing all the models available to research. The epidemiological researches, that are carried out on human populations, constitute the study model which can provide definitive evidence on the considered association. Among the several cancer sites, cancer of the lung, oral cavity and pharynx, esophagus, larynx, pancreas and urinary bladder are the sites more directly related with smoking habits. In this research the relationship between these cancer sites and tobacco smoking was studied examining both the international literature, and applying the cohort analysis to Italian mortality data from 1950 to 1983. The birth cohorts considered were those from 1875 to 1935 and data on cancer deaths are derived from official ISTAT publications. The analysis of cohort variation was carried out utilizing the indirect standardization method. The data on tobacco consumption, from 1900 to 1985, was obtained from official publication of the Administration of the State Monopolies or from unpublished material kindly provided by the same Administration. Regarding lung cancer, literature data emphasize the relationship between the disease frequency and age of starting smoking and the type of tobacco smoked. In Italy cohort variation seems to indicate an increased risk in mortality for men born before 1925, but there are indications of levelling off after this year. Analysis of the consumption of different types of tobacco products since 1900 suggests that the trends of mortality with time in different birth cohorts are explicable in terms of changes in the use of cigarettes, with high tar content up to 1940-1950, with low tar content and filter tipped after the 50s. Regarding females from the cohort variation it can be inferred that in Italy women began to smoke more recently and tobacco consumption is referred, almost exclusively, to low-tar and filter-tipped cigarettes. For larynx cancer, the literature data report that the relative risk is related to smoking habits and the present analysis shows a cohort variation very similar to that for lung cancer. Smoking habits, alcohol consumption, and their interaction, constitute the principal risk factor both for esophagus cancer and that of oral cavity and pharynx. In Italy the risk derived from alcohol consumption has influenced the trends of cohort variation relative to these two sites, which contrary to lung and larynx cohort trends, shows some fluctuations in mortality in males before 1921 and a progressive increase after this year. The relationship relative to urinary bladder and pancreas cancer is less evident.(ABSTRACT TRUNCATED AT 400 WORDS)

The relationship between marital status and cancer incidence was examined based on 49,191 incident cases aged 30 or over in 1980-1984 by using the data from Aichi Cancer Registry and census data. Although married and widowed people did not show increased incidence for any cancer site studied, single and divorced people showed statistically significantly increased or decreased risks for several sites of cancer. Single males showed an increased risk for esophageal cancer and a decreased risk for lung cancer. Divorced males showed increased risks for cancers of the mouth & pharynx, esophagus, liver, skin and brain. Single females showed increased risks for cancers of the esophagus, stomach, small intestine, liver, pancreas, lung, breast, corpus uteri, ovary & fallopian tube and other female genital organs and a decreased risk for cervical cancer. Divorced females showed increased risks for cancers of the larynx, breast, all parts of uterus and cervix uteri and a decreased risk for biliary tract cancer. The increased risk for breast cancer in single females was more pronounced in older age groups and the increased risks for several sites of cancer in divorced people were more pronounced in younger age groups. These findings may be partly explained by differences in reproductive factors and life style, especially smoking and drinking habits.

Among 337 cases of surgically resected lung cancer from April 1977 to March 1984, there were 24 cases (7.12%) of multiple primary cancers including 22 cases of double cancer and one case each of triple and quadruple cancer. They consisted of 17 males and 7 females and the patient age at the time of the lung resection ranged from 32 to 81 years old (average: 67.4). In double cancer cases, the most common site of the other primary cancer was the lung (9 cases), followed by the stomach (5 cases), the colon (4 cases), the pancreas (2 cases), and there was one case each of the salivary gland and the skin. The cases of triple and quadruple cancer involved multiple primary lung cancer associated with mammary and esophageal cancer, respectively. There were 14 synchronous and 8 metachronous cases. The histology of lung cancer in 13 cases of double cancer was adenocarcinoma in 6, squamous cell carcinoma in 2, large cell carcinoma in 3, small cell carcinoma in 1, and adenosquamous cell carcinoma in 1. The histology of 11 cases of double or triple primary lung cancers was squamous cell carcinoma in 17, adenocarcinoma in 5, and large cell carcinoma in 1. In 24 cases 19 lobectomies, 4 pneumonectomies and one partial resection of the lung was performed for the first primary lung cancer. All cancer lesions of other organs apart from the lung were also surgically resected.(ABSTRACT TRUNCATED AT 250 WORDS)

The omentum has been known to have a remarkable power of repair through neovascularization and scavenger function. Nine patients have been treated with the pedicled omentum. In 4 patients the omentum was used to obtain healing in the presence of infection. Bronchial fistulas were successfully closed in 3 patients with lung cancer and bronchial anastomotic leakage was repaired in one patient who received carinal reconstruction. In 5 patients, all of them had simultaneous resection of thoracic esophagus, the preventive use of omentum made a good result in two tracheoplasties, one pneumonectomy and one terminal tracheostomy. But one patient with esophago-tracheofistula after irradiation to esophageal cancer developed tracheal necrosis postoperatively. The omentum is useful in the case of postoperative empyema with bronchial fistula especially in patient with lung cancer. In the case of tracheobronchial resection after radiation therapy or with resection of thoracic esophagus, the suture line should be wrapped by omentum to prevent anastomotic leakage.

Imipenem/cilastatin sodium (IMP/CS) was administered to patients with severe infections complicated by hematological disorders and solid tumors to assess its efficacy and safety. Primary diseases in this series of 76 cases included 37 cases of hematological disorders (acute leukemia in 25 cases, malignant lymphoma in 7 cases, aplastic anemia in 3 cases and 2 other diseases) and 38 cases of solid tumors (lung cancer in 7 cases, gastric cancer in 11 cases, esophageal cancer in 6 cases, pancreatic cancer in 3 cases, bile duct cancer in 4 cases, hepatocellular cancer in 3 cases, and 4 other diseases). Following results were obtained. 1. Types of infection in hematological diseases were sepsis in 5 cases, suspected sepsis in 24 cases, pneumonia in 5 cases and 3 others. The efficacy rates were 100% in sepsis, 62.5% in suspected sepsis, 80% in pneumonia and 73% in all cases. 2. Types of infection in solid tumors were sepsis in 2 cases, suspected sepsis in 13 cases, pneumonia in 10 cases, cholecystitis in 2 cases, cholangitis in 5 cases, liver abscess in 2 cases, and 4 others. The efficacy rates were 50% in sepsis, 69.2% in suspected sepsis, 80% in pneumonia, and 71.1% in all cases. 3. IPM/CS was administered in single use in 66 cases and in combination with other antibiotics in 9 cases. The efficacy rate in the single use was 72.7% and that in the combination use was 66.7%. 4. The efficacy rate in 35 cases of first use was 71.4% and that in 40 cases of second use was 72.5%.(ABSTRACT TRUNCATED AT 250 WORDS)

There were 14 patients with a mean age of 65 years (ranged from 47 to 77) who had severe coronary artery disease associated with cancer of other organs. Stomach cancer was in 8 patients, breast cancer in 2, lung cancer in 2, rectum cancer in 1, and esophagus cancer in 1. They were treated with sequence of coronary artery revascularization and surgery for cancer; 9 patients in a two-staged fashion and 5 recent patients in a simultaneous one. In the series of simultaneous procedure, A-C bypass was combined with left ventricular aneurysmectomy in one patient and closure of ASD in another. There was no cardiac complication in both series, but one death from the complication of surgery for cancer in the staged series. Three patients in the staged series could not help being postponed the surgery for cancer by slow recovery from A-C bypass. In conclusion, coronary artery revascularization should anticipate surgery for cancer and simultaneous combined procedures should be chosen when possible.

The nucleoid sedimentation technique was developed to analyze DNA repair capacity in 108 cancer patients (esophageal cancer 34, lung cancer 24 and ovarian cancer 50) and 139 normal persons. After exposing lymphocytes to UV in radiation at the dose of 2.5 microJ/mm2, the cells were incubated for different periods of time at 37 degrees C for repairing the damaged DNA. The nucleoid sedimentation distance which corresponds to DNA repair capacity was determined. It was found that most normal persons finished the process of DNA repair in II hours while the cancer patients could not do so even 17 hours after incubation. This study showed that decreased DNA repair capacity may be a component of the genetically determined susceptibility to cancer.

The mortality experience of 1392 lead-zinc-silver miners (Gorno, Northern Italy) employed in the period 1/1/1950-31/12/1980 and followed-up to 31/12/1986 was examined. Two separate estimates of the radon exposure level are available: 0.60 and 0.36 working levels respectively. The silica exposure level was not assessed. Vital status was ascertained for 95.6% of the cohort members and their mortality was compared with expected deaths based on national rates. Significant excess mortality from esophageal cancer, stomach cancer, lung cancer, respiratory tuberculosis, respiratory diseases and deaths from external causes was found among underground miners. Surface workers show significantly increased mortality from liver and bile ducts cancer, hepatic cirrhosis, respiratory tuberculosis and respiratory diseases. Based on the 16.4 excess lung cancer cases among underground miners and their cumulative radon exposure, an attributable risk estimate ranging from 9.78 and 16.31 cases per million person-years and WLM (Working Level Month) was calculated.
