From January 1987 to May 1988, 32 cases with tracheobronchial lesions were treated with Nd-YAG laser. Complete restoration of the airway was achieved in one case of leiomyoma, adenoma, carcinoid and mucous epithelioma each, 2 cases of polyp and 7 cases of granuloma. Significant restoration was seen in one case of granuloma, 2 cases of hematoma and papilloma, each, 3 cases of amyloidosis and partial restoration in one case of granuloma. The remaining 10 cases with squamous cell carcinoma and adenocarcinoma with severe airway obstruction were treated by Nd-YAG laser for palliative purpose only. Four of them revealed significant remission and 6 responded with partial remission. No severe complication was observed during or after the procedures. Nd-YAG laser treatment provides a new curative method avoiding resection of the lung in benign lesions and a palliative therapy for unresectable obstructive malignant tumors.

Both SPA immunological fecal occult blood test (SPA FOBT test) and detection of T-antigen in rectal mucus (Shams' test) were used as screening tests in asymptomatic mass screening to evaluate the complementary effect of both tests for detection of colorectal cancers. SPA FOBT test showed a positive rate of 11.1% and shams' test 8.9% among 7,740 subjects. In 498 cases with positive screening test, 11 cases of carcinomas and 88 adenomas were found with colonoscopy. Only 9 cancers and 55 adenomas showed positive result in SPA FOBT test and 8 cancers and 51 adenomas in Shams' test. Both tests combined could enhance the detective rate of cancer in asymptomatic mass screening from 81.8% with SPA FOBT test or 72.7% with Shams' test to 90.9%. This complementary effect was more obvious in adenoma detection. It is suggested that there were some shortcomings in sequential FOBT test for cancer detection, the combined use of the two different screening tests for detection of colorectal cancer could decrease the rate of missed detection.

We reported seven patients with adrenal "incidentaloma", diagnosed with ultrasonography and/or computed tomography and confirmed by operation and pathological examination. Three of them were pathologically diagnosed as pheochromocytoma and one each as mixed cell adenoma, bilateral adrenocortical adenoma, leiomyoma and adrenocortical carcinoma. Only one "incidentaloma" had cortisol-secreting function. The diagnosis and management of adrenal "incidentaloma" were discussed.

The authors collected 14 cases of early gastric cancer located in the mucosa and precancerous lesions which were resected with endoscopic mucosectomy. These lesions were as follows: 6 cases were early cancer (IIc type: 4 cases; IIa type: 2 cases); 3 cases were severe dysplasia; 5 cases were adenoma, Yamada I type. The size of all the lesions was less than 20mm. Four cases of early gastric cancer were resected completely. Two cases were resected incompletely, but radical gastrectomy was performed one month after endoscopic mucosectomy. All the three cases of severe dysplasia had complete resection. But two of them received resection twice. Five cases of adenoma were also resected completely. The criteria of complete endoscopic resection were those reported in the Japanese literature. All cases have been followed up for 4-41 months; endoscopic and histological studies showed that there were no residual and recurrent cancer cells. The complete resection rate was 85.7% (12/14). The results suggest that endoscopic mucosectomy can be applied to the patients with early gastric cancer located in the mucosa and precancerous lesions less than 20mm in size, which can be resected completely. This method is safe, entails less complications and is especially suitable for the old and weak patients.

Both deleted in colorectal carcinoma (DCC) and mutated in colorectal carcinomas (MCC) genes are newly found tumour suppresser genes in colorectal carcinomas. In this study mutations of DCC gene and loss of heterozygosity (LOH) of MCC gene were detected with Southern blot and PCR methods respectively. The study consisted of 30 cases of colorectal adenoma (10 with mild, 10 with moderate and 10 with severe dysplasia) and 33 cases of colorectal carcinomas (13 highly, 10 moderately and 10 poorly differentiated, meanwhile 9 in Dukes A, 10 in B and 14 in C stage). Their paired normal colorectal mucosa served as control. The results were as follows: mutation of DCC was not found in any specimen with normal mucosa or with adenoma of mild and moderate dysplaaia, while it was found in one if those with severe dysplasia. Mutation of DCC was, however, found in 7 of the 33 specimens with carcinoma and there was a correlation between the positive rate and the differentiation or staging of the carcinoma. LOH of MCC was not found in normal mucosa, but it was found in 2/10, 3/10 and 4/10 of the adenoma specimens with mild, moderate and severe dysplasia respectively. 18/33 of the carcinoma specimens was found to have LOH of MCC and there was also a correlation between the positive rate and the differentiation or staging of the carcinoma. These results suggest that the frequency of multiple gene changes increase with poor differentiation and increased staging of colorectal carcinoma.

Endothelin-1 (ET-1) receptors of normal adrenal gland (ADR, 6 cases), aldosterone-producing adenoma (APA, 5 cases), idiopathic hyperaldosteronism (IHA, 4 cases) and pheochromocytoma (PHE, 6 cases) in human were measured by radioligand binding assay (RBA) of receptors. Binding studies using 125I-ET-1 as a radio ligand showed the presence of a single class of high-affinity binding sites for ET-1 in all of the above tissues. The values of dissociation constant (Kd) of ET-1 for its receptor were similar in ADR, APA and IHA (28.3 +/- 2.5, 27.9 +/- 6.1, 27.7 +/- 1.9 pmol/L, respectively), but the maximal binding capacity (Bmax) of ET receptor tended to be lower in APA tissue (107.2 +/- 13.2 fmol/mg protein) in comparison with ADR (P < 0.01) and IHA (P < 0.05, 274.9 +/- 40.8, 247.0 +/- 19.8 fmol/mg protein, respectively). Both the Kd (50.8 +/- 5.1 pmol/L) and Bmax (675.3 +/- 93.7 fmol/mg protein) in PHE were higher than those in ADR (P < 0.01), APA (P < 0.01) or IHA (P < 0.05 for Kd, P < 0.01 for Bmax). Our data may suggest that there is the down-regulation for ET-1 receptor in APA and support the concept of an important role of ET-1 in the paracrine-autocrine regulation of aldosterone and catecholamine secretion in the adrenal and adrenal tumors.
