BACKGROUND: Studies of immune response for cancer have demonstrated that the antitumor immune response plays a role in competing against the growth of cancer cells and is frequently altered in advanced cancer. METHODS: We evaluated the changes of peripheral blood lymphocytes and their subsets during preoperative and postoperative periods according to the time sequence of the postoperative condition in gastrointestinal carcinoma patients. Lymphocyte surface markers were determined in 39 stomach cancer patients and 33 colon cancer patients by using the indirect immunofluorescence technique with monoclonal antibodies. The patient's body weights, hemoglobin, hematocrits, total protein, and albumin were also measured preoperatively at and 1, 3, 6, 12, 18, and 24 months postoperatively. RESULTS: There were significant differences of clinico-laboratory findings between the preoperative and the postoperative periods except for hemoglobin, total protein, and albumin in postoperative course. The total leukocyte count significantly decreased from the postoperative 6th month. The lymphocyte count significantly increased from the postoperative 3rd month. The granulocytes decreased significantly in the postoperative 6th month. The T cells and B cells decreased in the postoperative 3rd month and 1st month, respectively. CD8 increased in the postoperative 3rd month and NK cells also increased in the postoperative 3rd, 6th and 24th months. Other peripheral lymphocytes and their subsets showed no significant differences. The changes in the lymphocyte subsets according to stage were not statistically significant (p<0.005). CONCLUSIONS: The postoperative changes in lymphocytes, granulocytes, and NK cells were significantly different compared with preoperative levels, but these results did not correlate with postoperative survival and recurrence rate because of the short postoperative follow-up periods.

PURPOSE: The aim of this study was to analyze the research trends of quality of life (QOL) after gastrectomy among gastric cancer patients in Korea and to make suggestions for future studies. METHODS: A literature search was done using Pubmed, CINHAL, and Korean databases in Korean and English. RESULTS: A total of 53 studies from 1993 to 2015 were analyzed. Of 53 papers, 6 (11.3%) were doctoral dissertations and master's theses, and 47 (88.7%) were from academic journals. All of the studies (100%) used quantitative research designs. The European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ)-C30 and EORTC QLQ-STO22 were mostly used to evaluate QOL in the studies. The main research issues were varied, in particular, the most common subjects of studies were QOL related to the evaluation of treatment methods. CONCLUSION: Further studies about QOL after gastrectomy with gastric cancer patients need to be done with various approaches such as intervention studies to improve QOL, qualitative studies, and multidisciplinary research.

Bariatric surgery is considered the only effective method of achieving long-term weight loss and ameliorating obesity-associated comorbidities in morbidly obese patients. However bariatric surgery is associated with risks of nutritional deficiencies and malnutrition. Therefore, postoperative nutritional follow-up and supplementation of vitamins and trace elements should be recommended. In this review, we provide essential information on nutritional complications and nutritional management after bariatric surgery.

Aneurogenic pulmonary edema(NPE) following an aneurysmal subarachnoid hemorrhage(SAH) is a rare but devastating complication. The authors analyzed the clinical characteristics, therapeutic problems and management results from our cases in order to throughly evaluate for future therapeutic guide for such patients. There were seven patients diagnosed as NPE out of 546 patients who were admitted within one day following a SAH(1.3%) during the past 13 years. They were relatively young(average 51.3 years), had poor clinical grades on admission and had large amount of SAH. Hypotension and hypoxia on admission were also characteristics. Good results were obtained in 4 of the 7 patients by rapid correction of hypoxia and hypotension with intubation, mechanical ventilation and with positive end-expiratory pressure, diuretics and hypertensive drugs. We conclude that NPE following SAH may be triggered by an acute rise in intracranial pressure followed by a simultaneous decrease of the function of the heart and lungs. Although the patients had shown fulminant clinical state on admission, we recommend aggressive management of these patients because some of these patients can recover without neurological deficits by an aggressive treatment.

Until now, surgical treatment of bile duct carcinoma has been unsatisfactory. There have been few reports dealing with the clinical significance of epidermal growth factor receptor(EGFR) and c-erbB-2 in bile duct cancer. To evaluate epidermal growth factor receptor(EGFR) and c-erbB-2 protein as a marker for prognosis, we analyzed the data and outcome of 32 cases of extrahepatic bile duct carcinoma immunohistologically, as well as clinicopathologically. The expressions of EGFR and c-erbB-2 showed in 71.9%(23/32) and 34.4%(11/32), respectively. The expression of EGFR was closely associated with the expression of c-erbB-2 (p<0.05). The expression rate of EGFR was significantly higher in well-differentiated cancer than in poorly-differentiated cancer (p<0.05), but was not related to stage, or lymph node metastasis. The expression of c-erbB-2 was not related to stage, lymph node metastasis, and differentiation. The expressions of EGFR and c-erbB-2 did not correlate with survival. In conclusion, the expression of EGFR or c-erbB-2 may be used as a tumor marker, but not as a prognostic factor in extrahepatic bile duct cancer.

In order to find out the effect of blood glucose on the ischemic brain injury, the authors studied the relationship between the blood glucose level and the infarct volume in a focal cerebral ischemia-reperfusion model in a series of 60 adult rats. The experimental animals were divided into 4 groups of 15 rats: rats in group I were allowed free access to food until ischemic insults: rats in group II were fasted for 24 hours prior to ischemic insult: rats in group III were fed but received intraperitoneal injection of 1.7unit/kg of insulin 50 minutes before the onset of ischemia: and rats in group IV were fed and received intraperitoneal injection of 2g/kg of 50% glucose during ischemia. The ischemia was made through unilateral occlusion of the middle cerebral artery(MCA) by inserting a 16mm length of 4-0 nylon surgical thread through the internal carotid artery as well as occlusion of both common carotid arteries(CCA) using nontraumatic aneurysm clips. Reperfusion was induced by pulling the thread that occluded the MCA as well as removing the aneurysm clips from both of the CCAs. Each group was further divided into a(2 hour), b(4 hour), and c(6 hour) subgroups of 5 rats according to the duration of ischemia. All animal were killed 3 hours after reperfusion, and infarct volume determined by triphenyltetrazolium chloride was calculated by a computer image software. The results showed that rats of glucose loaded during ischemia(group IV) developed the highest blood glucose levels during ischemia and post-ischemia and the largest infarct volume among groups. The rats which were fed until ischemic insult(group I) developed higher blood glucose levels and larger infarct volume than those developed in group II and III. The rats of group III developed higher blood glucose levels and larger infarct volume than group II. According to our data, lowering the blood glucose level by fasting or intraperitoneal injection of insulin reduced the infarct volme in model of transient focal cerebral ischemia. These results suggest that maintenance of low level of blood glucose during early phase of cerebral infarction may reduce volume of infarction and neurological sequelae.

Antihypertensive effect and side effect of Tripamide(Normonal(R)) was studied in 22 cases of essential hypertension using 15mg once daily regimen for average period of 9 weeks. 1) Antihypertensive effect Average reduction of 25mmHg in systolic and 19mmHg in systolic and 19 mmHg in diastolic pressure was observed and reduction rate was 15.7% and 17.6% respectively. The overall effect rate was 86%. The blood pressure lowered significantly in 1 week of treatment both in systolic and diastolic pressure and the extent of fall in systolic pressure approached near the level of maximum reduction in 2 weeks of administration and that of diastolic after 5 weeks of treatment. 2) Laboratory tests and side effect There was no significant changes in individual and mean value of Na, K, Cl, BUN, creatinine, uric acid, fasting blood sugar, cholesterol, GOT, GPT studied before and after treatment except one case showing elevation of uric acid. No significant side effect was observed during trial except of 2 cases of transient diuretic effect.

PURPOSE: This study was carried out to evaluate the impact of combined splenectomy with total gastrectomy on survival and postoperative morbidity in advanced gastric cancer. PATIENTS AND METHODS: We performed a retrospective analysis of 193 patients who underwent curative resection among 289 patients with total gastrectomy during the period of Sep. 1983 through Dec. 1995 at the Department of Surgery, Korea University Hospital. RESULTS: Out of 11 clinicopathologic factors, 5 were associated with splenectomy through univariate analysis. The incidence of splenectomy increased when the patients with advanced gastric cancer had Borrmann type III, Gross T3 & T4 stage, greater than 4 cm of tumor size, Serosal invasion, or UICC stage IIIb, IV (p<0.05). Postoperative complication occurred more commonly in splenectomy group than in non-splenectomy group (20.2% vs 16.9%). The 5-year survival rate of Stage II was lower in splenectomy group than in non-splenectomy group (63.5% vs 83.5%) but that of Stage III was higher in splenectomy group than in non-splenectomy group (22.8% vs 17.3%), there was no significant difference between the survival rates across different stages. CONCLUSION: We could not find any beneficial effect of splenectomy in gastric cancer patients who underwent curative total gastrectomy in this retrospective analysis. There was no clinical evidence to support splenectomy as a general policy in patients with total gastrectomy. We conclude that the randomized prospective clinical trials using more precise criteria for the indication of splenectomy are needed in order to assess the beneficial effect of splenectomy.
