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.

The bcl-2 proto-oncogene was first described as a result of the chromosomal translocation t(14:18) seen in a large number of follicular B-cell lines. Bcl-2 is so far unique a proto-oncogene in that it codes for an inner mitochondrial membrane protein. This protein regulates the programmed cell death called apoptosis. This study was designed to investigate expression of bcl-2 protein in 81 human breast cancer by using immunohistochemical staining with the monoclonal antibody of bcl-2 protein. Also this factor was compared with established clinicopathological prognostic factors and hormone receptors. The bcl-2 protein expression was positive in 38(47%) cases and was negative in 43(53%) cases. There was significant correlation between bcl-2 protein expression and histologic grade(p=0.014). Positive expression of bcl-2 protein was correlated with positive estrogen(p=0.051) and progesterone(p=0.059) receptors, but this correlation was not significant. Bcl-2 expression failed to show its prognostic role for overall(p=0.115) and disease free(p=0.214) survival. In conclusion, the bcl-2 protein is often expressed in half of breast cancer, and its expression is associated with histologic grade and hormone receptor status, but the overall and disease free survival of breast cancer patient do not appear to be influenced by bcl-2 protein expression.
