We report an autopsy case of the brain stem glioma that extended extensively in the brain stem itself and cephalad. This 18-year-old boy first presented with dizziness, vomiting and left side weakness with left facial palsy. Brain MRI revealed a diffusely infiltrative tumor involving whole medulla, pons and lower midbrain. A total of 4000 R was given with some alleviation of respiratory difficulty. He died one year after the onset. Autopsy revealed the tumor involving pons, a portion of medulla oblongata, and cerebellum. The tumor showed diffusely infiltrative pattern and extended along the periventricular area to the thalamus and corpus callosum. The cut surface was grayish white and solid. It also showed areas of myxoid degeneration and necrosis probably related to radiation therapy. Microscopically the tumor was a cellular and pleomorphic glioma that showed some astrocytic differentiation. It was diffuse without geographic necrosis.

7.Gastroduodenostomy after Gastrectomy for Gastric Cancer Comparative study of the single-layer and two-layer sutured anastomosis.
Journal of the Korean Surgical Society 2001;60(4):420-424
PURPOSE: The technique of anastomosis for gastroduodenostomy is thought to be of importance to success in the postoperative period and to the development of certain complications. Most surgeons a use two-layer anastomosis method. However, interest in single-layer anastomosis has increased. Therefore, we investigated the differences between single-layer and two-layer methods for anastomosis by comparing clinicopathological parameters and clinical courses. METHODS: This report is a retrospective clinical analysis of 265 patients of gastric cancer who underwent gastroduodenostomy following distal gastrectomy at the Department of Surgery, Chonbuk National University Hospital from Jan. 1991 to Dec. 1999. RESULTS: There was no significant difference observed between the two groups with regard to the mode of presentation, mean age, sex, or pathological characteristics of the tumor. The time for the anastomosis was shorter in the single-layer group (30.1+/-1.0 vs 37.1+/-2.1 minutes, p<0.001), the time of gas out was earlier in the single-layer group (4.4+/-1.1 vs 4.7+/-1.2 days, p=0.027) and the time of food intake was earlier in the single-layer group (5.7+/-0.8 vs 6.3+/-1.4 days, p<0.001) than in the two-layer group. Although the complication rate was not significantly different between the two groups, anastomotic leak was observed in 4 cases (2.7%) of the single-layer group and 3 cases (2.6%) of the two-layer group, and passage disorders were observed in 4 cases (2.7%) of the single-layer group and 5 cases (4.3%) of the two-layer group. CONCLUSION: A gastrodudenostomy using the single-layer anastomosis method has an advantage over the two-layer method for anastomosis with respect to the time for anastomosis, the time of gas out and time of food intake. Therefore the single-layer anastomosis method can be effectively employed in gastric cancer surgery.

8.Intraperitoneal Chemotherapy Against Serosal Invasion and Peritoneal Dissemination of Gastric Cancer with Activated Carbon Particles Adsorbing Mitomycin C: Prognosis and Complications.
Journal of the Korean Surgical Society 1997;52(5):694-701
Peritoneal carcinomatosis is a common cause of noncurability and the most common type of recurrence in surgical operations for gastric cancer. Activated carbon particles are taken up selectively by lymphatic tissues, which seem to be a primary site of peritoneal carcinomatosis in the peritoneal cavity, and adsorb a large amount of anticancer agent, such as mitomycin C, which is subsequently released slowly and for long periods. We carried out a retrospective study to determine if activated carbon particles adsorbing mitomycinC ( MMC-CH ) could improve the survival of patients who underwent radical resection for gastric cancer with serosal invasion and peritoneal dissemination and to evaluate the prognostic factors in patients receiving intraperitoneal MMC-CH therapy from January 1993 to January 1996. Those in the control group received no intraperitoneal chemotherapy and those in the MMC-CH group were given 50mg mitomycinC as MMC-CH before the surgical wound closure into the peritoneal cavity. The 3-year survival rates for the MMC-CH group in the case of S2 were 55%, and 17% in the case of S3. But the 3-year survival rate for the control group in the case of S2 was 32% and there was no survivor in S3 cases. In the cases of peritoneal dissemination, there were no survivor for the control group, but the 3-year survival rate for the MMC-CH group was 13%. The difference between the two groups was not statistically significant except positive papanicolaou smear and S3 cases at 3-year survival rates. There was a significant difference in morbidity after surgery between these two groups especially due to fever & hypotension and anastomotic leakage. Multivariative analysis using simple regression model in MMC-CH group has confirmed that the serosal invasion, positive Pap. smear and high stage had a significant impact on the survival rate after gastric resection. In conclusion, intraperitoneal chemotherapy with MMC-CH is effective in prolonging the survival time by prophylatic effect on peritoneal recurrence after curative resection of gastric cancer without significant complication and especially indicated in the cases of positive serosal invasion, positive Pap. smear in peritoneal cytology and high stage.

9.Comparative Study by Primary Tumor (T) and Nodal Involvement (N) in Stage II Gastric Cancer.

Journal of the Korean Surgical Society 2001;60(1):66-72
PURPOSE: This study was done to evaluate the differences in clinical parameters and survival rates between the primary tumor (T) and nodal involvement (N) in stage II cancers. METHODS: This report is a retrospective clinical analysis of 100 patients of stage II gastric cancer who were treated surgically at the Department of Surgery, Chonbuk National University Hospital from Jan. 1990 to Dec. 1999. Among the 100 patients, the pT3N0 group included 48 patients, and the pT2N1 group 52 patients. In this study, we used the UICC TNM staging system (the fourth edition). RESULTS: There were no significant differences except for age and tumor sizes between the pT3N0 and the pT2N1 groups with regard to the mode of presentation, sex, location of tumor, type of resection, lymph node dissection, Borrmann and Lauren classification, cell cytology, recurrence, number of resected lymph nodes, and the 5-year survival rate. Based on the number of lymph nodal metastases, no significant difference was observed in the 5-year survival rate, but based on the ratio of lymph nodal metastases, the 5-year survival rate for those with up to 20% frequency of metastases was 85.2% and the 5-year survival rate for those with greater than 20% was 40.0%, which is significant difference in the 5-year survival rate. CONCLUSION: In stage II gastric cancer, there was no difference between the pT3N0 and the pT2N1 group, except that in the pT2N1 group, a subdivision of the pN stage according to the ratio of lymph nodal metastases could be successfully applied to the clinical evaluation of stage II gastric cancer.

Journal of the Korean Gastric Cancer Association 2006;6(2):114-119
PURPOSE: The purpose of this study is to determine whether it is possible to evaluate patients with pN2 or pN3 early gastric cancer (EGC) as being in an advanced stage before and during the operation. MATERIALS AND METHODS: 1,430 patients underwent a gastrectomy for cancer from 1990 to 2003. Eight of the 552 patients with EGC included pN2 or pN3. The estimated clinical and surgical stage before and during the operation were compared to the pathological results, and a follow-up of progression was done. RESULTS: The patients were evenly distributed among all age groups with seven men and one woman. The pre-operative estimate of T1 by CT was 25% (2/8). In the main, the cT stage was over estimated. The estimate of over N2 was 50% (4/8). One patient was preoperatively staged as Ia . sT1 during operation was 57.1% (4/7), and the estimate of over N2 was 67% (4/6). Two patients were intraoperatively evaluated as Ia. Only one patient survived over 5 years, and the mean survival of these patients was 15 months (95% CI: 0~35.5). CONCLUSION: It was generally possible to evaluate patients with EGC of over pN2 as being in an advanced stage before and during the operation. Although very rare (2/552, 0.04%), there were EGC patients whose stages were not predictable at all. Therefore, more precise preoperative and intraoperative staging methods are warranted.
