Colorectal carcinoma in patients under 40 years and over 70 years of age is unusual but not rare. The prognosis of these two groups, compared with remainder of patients, is thought to be unfavorable. From Jan. 1981 to Dec. 1997, 541 patients with primary colorectal cancer who were treated by surgical resection were analyzed retrospectively. They were divided into three age groups according to the age at admission, i.e. under 40 years, over 70 years and between 40 and 69 years(control group). Among three age groups, sex ratio, tumor characteristics(size, location , depth of invasion, lymph node metastasis, liver metastasis, peritoneal metastasis, histopathologic classification, stage, DNA ploidy pattern), serum CEA level and survival were compared and analyzed. The results were as follows: 1) In the young patient group(52 cases), female predominence, large tumor size, high proportion of mucinous adenocarcinoma in histopathologic classification, more frequent metastasis to regional lymph node, frequent peritoneal metastasis and high incidence in tumor location at transverse colon were noted(p<0.05). 2) In the elderly group(69 cases), deep invasion of tumor(T4) was noted (p<0.05). In addition, among them, concomittent diseases were presented in 25 patients(36%). They were diabetes(8), cardiac arrhythmia(4), old myocardial infarction(2), liver cirrhosis(5), COPD(3), previous cancer(3). 3) The 5-year survival rates of the young patient group and that of elderly patient group were lower than that of the other(p<0.01). 4) There was no significant differences in liver metastasis, tumor stage, DNA ploidy pattern, serum CEA level among three age groups.

Twelve patients with inflammatory bowel disease had been operated at the department of surgery, Chonnam University Hospital during the period from March 1988 to February 1997. In this study, we report on the operative cases regarding age, sex, symptoms, duration of disease, location of disease, preoperative diagnosis, operative indication, frequency of operation, histopathologic findings and follow up. The results were as follows: 1) The male to female ratio in ulcerative colitis was 1 : 1, and the mean age was 54.5 years. In Crohn's disease, male to female ratio was 2.3 : 1 and the mean age was 42.1 years. 2) The mean duration of symptoms in ulcerative colitis was 39 months and in Crohn's disease was 13.9 months. The common symptoms in ulcerative colitis were abdominal pain, bloody diarrhea, indigestion, weight loss and in Crohn's disease abdominal pain, palpable mass, weight loss, indigestion. Extraintestinal symptoms in Crohn's disease were cholelithiasis like symptom, anal fistula, anal fissure. 3) The involvement site in ulcerative colitis was large bowel only, but in Crohn's disease small bowel (50%), large bowel (20%), small and large bowel (30%) were involved. 4) Preoperative diagnosis in ulcerative colitis was accurate, but in Crohn's disease accurate diagnosis was made only in 20% and the other cases were operated under the impression of different diseases or conditions (intestinal tuberculosis (50%), bowel perforation (20%), mechanical ileus (10%)). 5) The indication of surgery in ulcerative colitis was intractability to medical treatment, on the other hand, in Crohn's disease most operative cases were made under the emergentconditions (bowel perforation, bowel obstruction, enterocutaneous fistula, abdominal mass). The frequency of operation in ulcerative colitis were two times in one case, three times in one cases. In Crohn's disease half of cases experienced two or three times of surgery. The method of operation in ulcerative colitis was total proctocolectomy with J-pouch ileoanal anastomosis. In Crohn's disease resection of diseased bowel segment was performed.

BACKGROUND: Extended radical dissection of gastric cancer offers a more accurate stage, and complete removal of the metastatic lymph nodes raises the rate of curability. It has been thought for a long time that gastric cancer with paraaortic lymph-node metastasis is impossible to cure. However, with several reports of long-term survival of cases with paraaortic lymph-node metastasis, recently the procedure of paraaortic node dissection has become prevalent in Japan. METHODS: The study group was comprised with 348 patients of stage IV gastric cancer from among total of 2,015 patients with gastric cancer who had undergone gastric resection between 1979 and 1997 at the Department of Surgery, Chonnam University Hospital. Thirty-eight (38) of the 348 patients were paraaortic lymph-node positive (group I), 233 presented peritoneal metastasis (group II), and the remaining 77 presented liver metastasis (group III). The following factors were taken into consideration: age, sex, size of tumor, histopathologic classification, Borrmann type, location of tumor, DNA ploidy pattern, and survival rate. RESULTS: 1) In sex distribution, the third group (III) showed a statistically significant male predominence compared with the other groups (I=63.2%, II=67.4%, III=87.0%) (p<0.01). 2) In histopathologic classifications, well-differentiated tubular adenocarcinomas were more common in group III (I=10.5%, II=6.4%, III=22.0%). Poorly differentiated tubular adenocarcinomas were more common in group II (I=44.7%, II=59.2%, III=27.3%) (p<0.01). 3) In Borrmann types, type IV was more common in group II (I=7.9%, II=27.8%, III=9.1%) (p<0.01). 4) In tumor location, antral involvement of the tumor was presented in 55.3% of group I, 54.7% of group II, and 67.5% of group III whereas whole involvement of stomach was presented in 5.3% of group I, 15.0% of group II, and 5.2% of group III (p<0.01). 5)Group I had a significantly higher (37.9%) two-year survival rate than the other groups (II=10.9%, III=12.8%) (p<0.01). CONCLUSIONS: This study suggests a greater prognostic benefit for radical surgery in cases of paraaortic lymph-node metastsis than in cases involving other stage IV gastric cancers.

Recently, abnormalites in DNA content have been considered as a new prognostic factor in gastric cancer. However, whether abnormal DNA content can be used as a prognostic tool for gastric cancer is still unknown .For that reason, the relationship between the DNA ploidy pattern and the conventional clincopathologic findings was studied and the corresponding survival rates were compared. A group of 690 newly diagnosed and surgically resected gastric cancer specimens obtained from January 1986 to June 1996 were examined for DNA content by flow cytometry. The results showed that 411 cases (59.6%) had DNA diploidy and 279 cases (40.4%) had aneuploidy; DNA aneuploidy was significantly correlated to well differentiated adenocarcinoma, whereas diploidy was correlated to signet ring cell carcinoma. The DNA diploidy group was differentiated from the aneuploidy group by depth of invasion and nodal involvement. Tumor cells confined to mucosa and no involvement of the lymph node (N0) were significant in the diploidy group of gastric cancer. In addition, stage Ia was predominant in the diploidy group. However the results of surgical resection and the 5-year survival rates of patients in the two groups were not signifcantly different (p>0.05). We, therefore, propose that the DNA ploidy pattern is useful for evaluating tumor growth, including lymph-node involvement, but not for determining the survival and prognosis.

Telomere Length Changes in Colorectal Cancers and Polyps Telomere shortening and telomerase activation occur frequently in cases of colorectal carcinoma. In this study, we correlated the clinicopathological parameters with the telomere length in colorectal carcinomas, colonic polyps, and normal colonic tissues. We also investigated whether the telomere length changes reflect the biologic behavior of tumors and different modes of tumor development. Telomere length was determined by terminal restriction fragment Southern blot analysis in 20 invasive colorectal carcinomas and normal mucosa from the same patients. We also examined 20 colonic polyps and associated normal mucosa. Telomere shortening was detected in 16/20 (80%), and telomere elongation in 2/20 (10%) cases of colorectal carcinoma, and no changes in 2 subjects. In the colonic polyp patients, shortening was detected in 4/20 (20%), elongation in 6/20 (30%), and no change in 10/20 (50%). The frequency of telomere shortening was significantly different between colorectal carcinoma and polyp groups. Decreased telomere length was noted in 92.9% (13/14) of Dukes' C and 50% (3/6) of Dukes' B. The difference between these two sub-groups was statistically significant. This study suggests that the telomere length in colorectal carcinomas is decreased upon the development of malignancy. A significant difference in telomere length between polyps and invasive colorectal carcinomas may reflect a different biologic behavior of colorectal carcinomas.

Liver metastasis is reported about 5 to 7 percent of the time with primary gastric cancer. Advances in diagnostic tools, such as abdominal ultrasonography and abdominal CT, have made detection of liver metastases from primary gastric cancer easy. Many studies have reported on the benefit of hepatic resection for metastatic tumors from colorectal cancer. However, few reports exist on the treatment of metastatic liver tumors from primary gastric malignancy. We experienced 70 cases of gastric cancer with liver metastases among 1391 cases of gastric cancer during a 11-year period from 1986 to 1996, and we examined the relationship between the types of treatment and the mean survival time for those no cases. To that end, those patients were divided into 4 groups. Group A was comprised of 13 patients who underwent a gastrectomy with hepatic resection. Group B was comprised of 41 patients who underwent a gastrectomy with systemic chemotherapy. Group C was comprised of 3 patients who underwent a gastrectomy with chemoimmunotherapy via hepatic artery catheter. Group D was comprised of 13 patients who underwent a gastrojejunostomy only. The thirty-month survival rate of Group A was 23% and that of Group B was 13%. This difference between Groups A and B was statistically significant (p<0.05). In Group C, one patient died within 7 months, one patient died after 13 months of survival, and one patient was still living 3 months postoperatively. In Group D, no patient survived past 12 months. These results suggest that combined resection of the stomach and a part of the liver in gastric cancer patients with liver metastasis leads to longer survival time compared with other treatment methods, such as systemic chemotherapy and chemoimmunotherapy via hepatic artery cannulation.
