PURPOSE: An adrenalectomy is needed in about 10 to 25% of Cushing's syndrome cases due to adrenal adenoma, hyperplasia, or carcinoma. The purpose of this study is to compare the postoperative compli cations of an adrenalectomy between Cushing's and non-Cushing's patients. METHODS: Data were collected by reviewing the hospital charts of patients treated at Korea University from July 1987 to Jan. 1998 the clinical data were compared using statistical method. RESULTS: An adrenalectomy was performed in 77 patients, and the causes of the adrenalectomy were primary aldosteronism (25 cases), pheochr mocytoma (23 cases), Cushing's syndrome (20 cases), adrenal carcinoma (5 cases), non-functioning adre nal adenoma (2 cases), ganglioneuroma (1 case), and neuroblastoma (1 case). The causes of Cushing's syndrome were adenoma (16 cases), nodular hyperplasia (3 cases), and carcinoma (1 case). The types of adrenalectomy used were anterior (60 cases), posterior (14 cases), and lateral (3 cases). Postoperative complications were atelectasis, pneumonia, wound infection, paralytic ileus, intra-abdominal abscess, intra-abdominal bleeding, acute renal failure and psychosis, in order of frequency. The rate of post operative complications in patients with Cushing's syndrome was 85%, which was higher than rate of 31.6% (p=0.02). Postoperative respiratory complications, such as atelectasis and pneumonias, were more common for patients with Cushing's syndrome (p=0.02). In patients of Cushing's syndrome, the devel opment of postoperative complication was related to the length of the operation, the size of the tumor, the weight of the tumor, the site of the tumor, the pathology and the method of approach (p>0.05). CONCLUSION: The patients with Cushing's syndrome were prone to postoperative complications, and respiratory complications were the most common postoperative complication. Careful preoperative and postoperative respiratory management should reduce the complications of an adrenalectomy in patients with Cushing's syndrome.

PURPOSE: Oncogen or growth factor receptor such as phospholipase C isoenzyme gamma-1 (PLC gamma-1), epidermal growth factor receptor (EGFR), and Her-2/neu which related with tyrosin kinasemay and then regulating vell proliferation may have a role as prognostic factors for breast cancer. MATERIAL AND METHODS: With assumption that expression of PLC gamma-1, EGFR and Her-2/neu oncogene has close relationship with prognosis of breast cancer, 59 breast cancer patients who were operated upon at Korea University Hospital during a period of 6 years starting June 1988 to May 1994 were selected for this study. This study was carried out by comparing between expression of PLC gamma-1, EGFR and Her-2/neu oncogene and patient's survival rate. These expression were also compared with TNM system, estrogen and progesterone receptor and at same time these expressions were compared with each other to see whether there are any relationship among these expression. RESULTS: Expression of PLC gamma-1, EGFR and Her-2/neu were present in 42% (25/59), 46% (27/59) and 20% (12/59). The expression of PLC gamma-1 was closely related with the expression of EGFR (p<0.05) and Her-2/neu (p<0.05), but there were no relationship between the expression of PLC gamma-1 and hormonal receptors and TNM stage (p>0.05). The expression of EGFR was closely related with the expression of Her-2/neu (p<0.05) and hormone receptors (p<0.05), but there were no relationship between the expression of EGFR and pathologic TNM stage (p>0.05). The expression of Her-2/neu was not closely related with hormone receptors and TNM stage except axillary lymph node metastasis. There were close relationship between overall and disease free survival and PLC gamma-1 and Her-2/neu. But EGFR had only related with disease free survival rate. CONCLUSION: In conclusion, the expression of PLC gamma-1, EGFR and Her-2/neu oncogene in human breast cancer may be useful prognostic factors independently and it may potentiated its individual value as a prognostic factors if use them together.

Journal of the Korean Cancer Association 1999;31(4):663-669
PURPOSE: The etiology of breast cancer involves very complex factors such as genetic, hormonal, and dietary. The peak age of Korean breast cancer is much earlier, about ten years, than those of western countries. The role of p53 gene on the carcinogenesis has been studied since 1991. This study was designed for the evaluation of genetic factor by determining p53 gene mutations in Korean breast cancer. MATERIALS AND METHODS: Mutation screening on p53 tumor suppressor gene was examined with PCR-SSCP and nucleotide sequencing technique from the genomic DNA extracted from the 27 fresh-frozen breast cancer tissues. RESULTS: Mutations in p53 gene exon 5-7 were identified in 2 of 27 cases (7%). One had a missense mutation substituted gcg with ggg at codon 159, exon 5, and the other had a point mutation substituted tcc serine to tGc cysteine at codon 241, exon 7. CONCLUSION: Point mutation of p53 gene in breast cancer seems to be the major defect found in Korean patients. It is necessary to perform further study in mutation of other exon 2, 4, 8, 9, and 11 of p53 gene to compare the genetic backgrounds of Korean breast cancer with those of westerns.
