The neodymium-yttrium-aluminium-garnet laser (Nd-YAG laser) has proved to be useful therapeutic tool for the management of endobronchial lesions. Between February 1983 and January 1991, 16 patients received endobronchial laser therapy at the Nagasaki University Hospital, 7 patients for tracheal stenosis, and 9 for endobronchial obstruction. In 4 patients with tracheal stenosis, the therapy was performed in an emergency. The type of lesions were lung cancer in 7 patients, thyroid cancer in 3, tracheal tumor (squamous cell carcinoma, and chondrosarcoma) in 2, esophageal cancer in 1, bronchial submucosal tumor in 1, and tracheobronchial tuberculosis in 2. Good symptomatic relief was obtained in 13 patients. One patient died from massive bleeding in the left main stem bronchus. Reobstruction had occurred in 2 patients with cicatricial lesion in right main stem bronchus. In patients with an unresectable malignant lesion, concurrent radiotherapy was needed to prevent the reobstruction.

To noninvasively study positional effects on superior vena caval configuration in humans, endoscopic ultrasonography was performed in 34 subjects including 20 with lung cancer, 5 with esophageal cancer and 9 with other diseases. None of the these subjects had cardiovascular involvement or respiratory dysfunction. A fiberoptic esophagoscope equipped with a 7.5 MHz linear array ultrasonic transducer at its tip (EPE-703, Toshiba-Machida) was used for the study. The actual movement of the superior vena cava (SVC) was clearly observed at the hilar level in all cases. During the cardiac cycle the anteroposterior diameter of the SVC was observed to reach a maximum at the atrial systole and reached a minimum at the late ventricular systole. With respiration, the SVC increased in diameter during inspiration and decreased during expiration. Moreover M and B mode figures of the SVC wall were recorded in left (LLD) and right decubitus (RLD) and supine position (SUP) in 34 subjects. On quiet ventilation of FRC level the diameter of the SVC was unchanged. Both the maximal and minimal diameters of the SVC, which were corrected for body surface area (BSA), were 11.3 +/- 0.3 (mean +/- SEM) mm/m2 and 9.8 +/- 0.3 mm/m2 in right lateral decubitus position, 9.4 +/- 0.3 and 7.9 +/- 0.3 in the supine position, 8.5 +/- 0.3 and 7.1 +/- 0.3 in the left lateral decubitus position, respectively. The size of the SVC was the greatest in the right lateral decubitus position and was the smallest in left lateral decubitus position (p less than 0.01, multiple comparison). It was suggested that the geometry of the SVC is influenced by thoracic pressure and gravity and that it behaves very similarly to pulmonary vascular vessels as a collapsible tube.

The present report describes a 69-year-old man displaying the clinical features of the Cronkhite-Canada syndrome. After taking medicine for the common cold, he suffered hypogeusia and watery diarrhea, eruptions on the lower extremities and an 8 kg loss in body weight. All his finger and toenails began to fall out. He underwent an upper gastrointestinal examination, upon which multiple polyps of the stomach were detected. Three years later, he again developed diarrhea, bloody stools, body weight loss and eruptions on the lower extremities. An upper gastrointestinal series showed a diverticulum of the esophagus and multiple polyps in the stomach. A barium enema examination revealed polyps throughout the entire colon. Endoscopical biopsy specimens revealed juvenile type polyps and adenomas. The patient was treated with predonine therapy and, in a few days, his symptoms improved. Following the predonine therapy, an upper gastrointestinal endoscopy revealed superficial esophageal cancer and early gastric cancer. The patient received successful surgical treatment. Macroscopically, the esophageal cancer was of the superficial type, and its histologic type was that of moderately-differentiated squamous cell carcinoma. The gross finding on the stomach cancer was one of superficial depressed type, and its histologic type was that of well-differentiated tubular adenocarcinoma. One year later, lung cancer was detected. The gross appearance of the resected lung tumor was one of a grayish-white color and the neoplasm was histologically diagnosed as undifferentiated carcinoma, small and large cell type. The coexistence of carcinoma of the gastrointestinal tract with Cronkhite-Canada syndrome has been reported in 21 cases. We have found no report, however, of lung cancer associated with Cronkhite-Canada syndrome. The case described herein is, therefore, the first case of Cronkhite-Canada syndrome to be associated with esophageal, gastric and lung cancer.

Antioxidant micronutrients are one of the body's primary defenses against free radicals and reactive oxygen molecules. Carotenoids, vitamin C, and vitamin E trap these molecules, and selenium is an essential component of an antioxidant enzyme. There is considerable support from animal studies for a protective effect of antioxidant micronutrients on cancer. However, the role of these micronutrients in cancer prevention in humans is less clear. Diet studies suggest protective effects of fruits and vegetables on risk of cancer at several sites. Inverse associations between dietary carotenoids and serum beta-carotene and lung cancer have been observed repeatedly. Vitamin C has also been consistently inversely associated with risk of oral and esophageal cancer in diet studies and with stomach cancer in both diet and plasma studies. It remains unknown, however, whether carotenoids and vitamin C or some other component of fruits and vegetables, the primary sources of these micronutrients, prevent cancer in humans. Selenium has been inversely correlated with cancers at numerous sites in ecologic studies, but observational studies do not provide strong support for a protective effect of selenium on cancer at any site. There also is not strong support for a protective effect of vitamin E on cancer in humans. Results of studies on the association of antioxidant micronutrients with cancer at many sites are inconsistent. This could be due to lack of a true protective effect or could be related to methodologic problems in assessing dietary intake in epidemiologic studies.

A group of monoclonal antibodies against gastric cancer, pooled in equal proportions, was used to investigate their corresponding antigens (MG-Ags) in serum and body fluid of patients with gastrointestinal cancer and benign diseases using microsphere-ELISA method. The mean serum level (plus 3 standard deviations) in 59 normal subjects was arbitrarily set as the positive threshold value. The positive rate was found to be 68.8% (135/196) in sera of patients with gastric cancer, 70% (14/20) in colonic cancer, 72.2% (24/33) in rectal cancer, 43.8% (7/16) in esophageal cancer, 45.5% (5/11) in cholecystic cancer and 34.9% (15/43) in lung cancer, which, however, was not found in primary liver cancer, pancreatic cancer and ovarian cancer. In 214 patients with benign diseases, a false positive rate was 7.48%. In gastric juice and ascitic fluid of patients with gastric cancer, the positive rates were found to be 61.7% (27/44) and 83.3% (20/24) respectively. These antigens were also determined repeatedly in sera of patients with gastric cancer who had undergone gastrectomy. It was found that the level of MG-Ags in sera began to decrease at 8-10 days after operation. These results suggest that the determination of MG-Ags is useful in the diagnosis of gastrointestinal cancer and evaluation of the treatments.

To study the effect of the environments shared by spouses on the development of cancer and some chronic diseases, we analyzed the correspondence of disease history in 21,592 fathers and mothers using the baseline data of a population-based cohort study. The observed number of cases (O) whose parents had the same disease history was statistically significantly greater than the expected (E); the O/E ratio was 1.53 (95% confidence interval (CI): 1.43-1.63) for all malignant neoplasms, 5.22 (95% CI: 2.81-9.70) for esophageal cancer, 1.63 (95% CI: 1.37-1.93) for stomach cancer, 3.01 (95% CI: 1.89-4.79) for colorectal cancer, 3.90 (95% CI: 2.75-5.53) for liver cancer, 3.14 (95% CI: 1.95-5.08) for lung cancer, 6.73 (95% CI: 2.53-17.87) for bladder cancer, 1.66 (95% CI: 1.54-1.78) for apoplexy and 1.67 (95% CI: 1.51-1.86) for heart disease. The results of the present study suggest that the environmental factors shared by family members for a long time may contribute to familial aggregation of cancer and some chronic diseases.

The clinical application of photodynamic therapy (PDT) began in the late 1970's. Hematoporphyrin derivative has been used as a photosensitizer and recently Photofrin II (Dihematoporphyrin ether, DHE) was also developed as a second generation photosensitizer. The argon dye laseris used to excite the photosensitizer, however an eximer dye laser was recently developed as more effective laser. In a multicenter research study project team (7 institutions) on photodynamic therapy organized by the Ministry of Health and Welfare, 133 cases of gastric cancer (including 120 cases of early stage cancer), 209 cases of lung cancer (69 cases of early stage cancer), 66 cases of esophageal cancer (22 cases of early stage cancer), 68 cases of bladder cancer (68 cases of early stage cancer), and 86 cases of other organ cancers were treated. In early stage cancer cases 77.3% showed complete remission (CR) but among those the recurrence was 15.7% in lung cancer cases and opposed to 100% CR and 22.2% recurrence in gastric cancer cases, 80% CR and no recurrence in esophageal cancer cases, and 68.6% CR and 58.3% recurrence in bladder cancer cases. Especially in limited lesions less than 1 cm in diameter, the CR was obtained in 100% and the recurrence was recognized in only 1 (2.6%) of 28 lung cancer lesions, 100% CR and no recurrence was obtained in 30 lesions of gastric cancer and also 100% CR with no recurrence was recognized in 16 lesions in bladder cancer. This study suggests that PDT has the potential to cure early stage cancer lesions.

From July, 1978 to December, 1985, 1,138 cases of malignancies of the head and neck were treated at the authors' hospital, and up to June, 1986, 132 patients with multiple primary malignancies were detected. In all cases, the incidence rate of a multiple primary malignancy was 11.6%. In 45 (33.0%) of these head and neck cancer cases, the multiple cancer was detected simultaneously, and as for the other cases (66.7%), they were discovered metachronously. In patients with a cancer of the mesopharynx, the incidence rate of a multiple primary malignancy was the highest (25.8%), whereas in those with a cancer of the parotid gland and in those with a cancer of the hypopharynx, the incidence rates were 20.0% and 14.9%, respectively. In most patients the second malignancy occurred in the same head and neck region, and in the rest, the second malignancy was a gastric cancer, a lung cancer, or an esophageal cancer in that descending order. Of the 45 synchronous cancer cases, ten were a thyroid cancer, most being latent. In head and neck malignancies, the authors stress the importance of a precise investigation prior to start of therapy and of maintaining follow-up investigations after therapy.

We reviewed cases of re-thoracotomy performed for early complications after bronchoplastic procedures. One hundred and sixteen bronchoplasties were performed in our department over 20 years. The diseases for which bronchoplasty was undertaken were lung cancer in 102 patients (87.9%), tuberculous stenosis of the bronchus in eight, esophageal cancer in three, and trauma in three. The most frequent postoperative complication was difficulty of expectoration and atelectasis, which generally improved with conservative treatment. Re-thoracotomy was performed for early postoperative intrathoracic complications on 11 patients. The reasons for re-thoracotomy were bronchial anastomotic dehiscence in five cases, obstruction of bronchial anastomosis in two, atelectasis in two, and occlusion of anastomosis of pulmonary arterial angioplasty in two cases. All except two underwent re-thoracotomy within two weeks of the first operations. The operative procedures performed were completion pneumonectomy in six cases, re-bronchoplasty in three, suture of anastomotic dehiscence in two, patch closure of pericardial defect with aspiration of secretions in the atelectatic lobe in one, and partial decortication with suture closure of the alveolar fistula in one. Pedicled omental wrapping was applied to two patients with re-bronchoplasty and one with completion pneumonectomy. Post-operative complications after re-thoracotomy were anastomotic insufficiency in two cases, bronchopleural fistula in two, and pneumonia in one. Two patients underwent a third thoracotomy. There was no anastomotic dehiscence or bronchopleural fistula in the patients with pedicled omental wrapping. One patient died due to bronchopleural fistula within 30 days of re-thoracotomy. Six patients died of recurrence or pneumonia from 39 days to one year after re-thoracotomy.(ABSTRACT TRUNCATED AT 250 WORDS)

A sandwich enzyme immunoassay was set up to measure tumor associated antigen (antigen PA8-15) detected by monoclonal antibody PA8-15. The cut-off value was set at 55 U/ml. Tests on 437 sera samples from patients with malignant or benign diseases yielded the following positive percentages: esophageal cancer, 9.1%; gastric cancer, 23.1%; colorectal cancer, 44.8%; hepatoma, 32.6%; biliary tract cancer, 47.5%; pancreatic cancer, 84%; lung cancer, 30.8%; breast cancer, 16%; benign diseases, 13.2%. Positive antigen PA8-15 levels in patients with gastric, colorectal and pancreatic cancers, increased with the progression of clinical stage. When antigen PA8-15 was monitored in 11 various cancer cases before and after surgery, a decrease in PA8-15 value was revealed in all resected patients postoperatively, whereas a more than 100% increase in PA8-15 values was noted in non-resected patients. Compared with CEA and CA19-9, the highest positive PA8-15 rate was seen in pancreatic cancer patients. By combining the rates of positive sera obtained with each tumor marker, the overall percentage increased. These results suggest that measuring serum PA8-15 levels will aid in serological cancer diagnoses, particularly pancreatic cancer.
