Purpose: This study examined factors associated with the hospitalization of patients who visited the emergency department (ED) after deliberate self-poisoning. Methods: The medical records of the patients, who visited the ED at a tertiary teaching hospital after deliberate self-poisoning between March 2017 and December 2019, were reviewed retrospectively. Results: Fifty-seven in the hospitalization and 236 in the discharge group patients were included. The mean age in the hospitalization and discharge group was 48.8±20.4 and 41.8±19.1, respectively (p=0.020). Univariate analysis revealed statistically significant differences in age (p=0.020), mental status (p<0.001), request for help (p=0.046), chronic disease (p=0.036), substance ingested (p<0.001), and risk rescue-rating scale (p<0.001) between the two groups (hospitalization group and discharge group). In multiple logistic regression analysis for predicting the hospitalization of patients after deliberate self-poisoning, the Risk-Rescue Rating Scale (RRRS) was identified (OR=1.493, 95% confidential interval=1.330-1.675, p<0.001). Receiver operating characteristics analysis of RRRS for the decision to hospitalize showed a cut-off value of 38.9, with a sensitivity, specificity, and area under the curve of 96.4%, 77.0%, and 0.949, respectively. Conclusion The RRRS can be used to determine the hospitalization for patients who visited the ED after deliberate self-poisoning. Nevertheless, multicenter prospective studies will be needed to determine the generalisability of these results.

There has been considerable controversy over the prognosis of mucinous gastric enocarcinoma (MGC). In this study we analyzed the clinicopathologic fferences between MGC and non-mucinous gastric carcinoma (NMGC). In addition, e relationship between mucin content and other clinicopathologic variables, cluding prognosis in MGC, was also investigated. We reviewed 2118 patients th pathologically-confirmed gastric cancer who underwent gastrectomy at the partment of Surgery, Yonsei University College of Medicine, during the period tween Jan. 1987 and Dec. 1993. Among them, 130 patients had gastric carcinoma th extracellular mucin (MGC) and 1988 patients had gastric carcinoma without tracellular mucin (NMGC). We placed the MGC patients into two groups according mucin content: mucin content involving over 50% of the tumor (dominant type, = 94) and mucin content involving less than 50% of the tumor area (partial pe, n = 36). The results were as follows: MGC was more common in males than GC. The size of the tumor in MGC (mean 5.3 cm) was larger than that of NMGC ean 4.4 cm). The patients with MGC had a higher incidence of Borrmann type IV GC: 16.1%, NMGC: 9.9%), more frequent serosal invasion (MGC: 75.4%, NMGC: .6%), lymph-node metastasis (MGC: 75.4%, NMGC: 50.7%), and peritoneal tastasis (MGC: 10.0%, NMGC: 3.5%) than patients with NMGC. The patients with C were more advanced in stage at the time of diagnosis and had a worse overall -year survival rate (44.9%) than patients with NMGC (54.7%). However, the -year survival rate according to the stage of MGC was similar to that of NMGC. ere were no significant differences between the mucin content and other thologic variables, including prognosis, i.e. similar biologic behavior tween dominant type MGC and partial type MGC. In conclusion, we suggest that C was more frequently diagnosed in advanced stage than NMGC with a poorer ognosis and that it is reasonable to consider the carcinoma with mucin content volving more than 30% of the tumor area as MGC.

PURPOSE: Prognosis of primary gastric cancer invading neighboring organs is very poor. However, with en bloc resection, a relatively favorable prognosis can be expected even in patients with such advanced cancer. But there has been controversy on the effectiveness of gastrectomy combined with en bloc resection of the invaded organs, and we conducted this study to evaluate the prognostic effects as well as the outcome of the combined resection. MATERIALS AND METHODS: Among 2,603 who underwent gastrectomy due to gastric carcinoma from January 1987 to December 1994 at the Department of Surgery, Yonsei University College of Medicine, 157 patients (6.0%) in whom curative combined resections of grossly invaded adjacent organs (cT4) were perfonned entered this study. Any case with distant metastasis was excluded. Comparisons and multivariate analysis between the invasion (pT3) group and the non-invasion (pT4) group were made for age, sex, tumor size, location, Borrmann type, depth of invasion, lymph node metastasis, histologic type and 5-year survival rate. RESULTS: One-organ combined resection was done in 60 (38.2%) patients; Two-organ, in 80 (51.0%) patients; and three-organ, in 17 (10.8%) patients. Most commonly combined organ was distal pancreas and transverse colon was the next. Histologic confirmation of invasion was made in 40.9%. 157 patients with T4 were divided into pT3 or pT4. Significant differences were found in type of operation, location of tumor, and TNM staging. Postoperative complications of combined resection were observed in 48 cases (30.6%) and the wound infection was the most frequent one. There were only 2 cases (1.3%) of immediate postoperative mortality in the combined group, and the causes of death were pulmonary complication and acute renal failure. Five-year survival rate (5-YSR) of pT3 group was 43.0% and that of pT4 was 26.2%. In comparison of 5-YSR according to TNM stages, no significant difference was found between pT3 and pT4 (45.0% vs. 66.7% in IIIa; 25.4% vs. 18.4% in IV). No difference of 5-YSR was observed in the groups categorized according to the number of resected organs. The comparison of 5-YSR between the 157 curatively-combined cases and the 63 palliatively-combined cases showed a significant difference (35.6% vs. 4.2%, p=0.000). Multivariate analysis showed that lymph node metastasis and microscopic tumor invasion served as significant parametets. CONCLUSION: En bloc combined resection of adjacent invaded organs along with systematic lymph node dissection would be beneficial to gastric cancer patients with neighboring organ invasion.

PURPOSE: Adenosquamous carcinoma, a rare malignant tumor of the stomach, is characterized by two different cell components, one adenomatous and the other squamous component. Its clinicopathologic feature and prognosis are quite different from the ordinary adenocarcinomas. We report our experience of 9 such cases. MATERIALS AND METHODS: Clinical and pathologic features were reviewed for the 9 patients who undenwent gastrectomies and were confirmed as adenosquamous carcinoma by pathologists during the 10-year period of from 1987 to 1998. Postoperative adjuvant therapy and prognosis were also reviewed. RESULTS: The ages of 6 male and 3 female patients ranged from 30 to 59, with the median age of 48. Total gastrectomy was done in 4 cases, while other underwent subtotal gastrectomy. Curative resection was done in four cases. Fourteeen additional organs were resected concomitantly due to suspicious tumor invasion and among them 9 organs were histologically confirmed for tumor invasion. The mean tumor size was 7.4 cm (2.5-27 cm) and all cases were pathologically advanced. One case showed peritoneal seeding and 3 cases showed hepatic metastases. There were 7 cases of stage IV disease by the UICC TNM classification (5th ed.) and the other two were stage II and stage IIlb respectively. Eight cases received postoperative adjuvant chemotherapy comprising S-FU, DDP, adriamycin, picibanil or VP-16. Of 9 patients, 6 died and the overall 5-year survival rate was 15.3%. CONCLUSION: Adenosquamous cancer of stomach is regarded as a disease of unfavorable prognosis, which was confirmed by this study. The treatments were not quite different from those for other stomach cancers. Although more cases and further investigations are essential for complete understanding of the clinical prognosis and proper treatment of the gastric adenosquamous cancer, early diagnosis, curative resection and close postoperative follow-ups are currently available options for better outcome of this disease.

There has been a considerable controversy on the prognosis of the mucinous gastric adenocarcinoma(MGC). In this study we analyzed the clinicopathologic differences between MGC and non-mucinous gastric carcinoma(NMGC). In addition, the relationship between mucin content and other clinicopathologic variables, including prognosis in MGC was examined. We reviewed 2118 patients with pathologically confirmed gastric cancer who had underwent gastrectomy at the department of surgery of Yonsei University College of Medicine, during the period between Jan. 1987 and Dec. 1993. Among them, 130 patients had gastric cancer with extracellular mucin(MGC) and 1988 patients had gastric carcinoma without extracellular mucin(NMGC). We studied the MGC patients into two groups according to mucin content: mucin content involving over 50% of the tumor(dominant type, n=94) and mucin content involving less than 50% of the tumor area(partial type, n=36). The results are as follows: The MGC was more common in male then NMGC. The size of tumor in MGC was larger than that of NMGC. The patients with MGC had higher incidence of Borrmann type IV, more frequent serosal invasion, lymph nodes metastasis and peritoneal metastasis than the patients with NMGC. The patients with MGC had more advanced stage at the time of diagnosis and worse overall 5-year survival rate than the patients with NMGC. But the 5-year survival rate according to the stage of MGC was similar to that of NMGC. There were no significant differences between the mucin content and other pathologic variables including prognosis. So we suggested that MGC has worse prognosis than NMGC and it is reasonable to consider the carcinoma with mucin content involving less than 50% of the tumor area as MGC.

PURPOSE: Even with excellent surgical outcome, recurrence of early gastric cancer (EGC) after a curative resection is not declining because the incidence of EGC is increasing. The aim of this study was to propose an appropriate treatment strategy by assessing the risk factors for recurrence of curatively resected early gastric cancer. MATENRIALS AND METHODS: Of 3662 patients who had undergone gastric resections for gastric cancer from 1987 to 1996, the cases of 1050 curatively resected EGC patients were reviewed retrospectively. Among those 1050 patients, 50 patients (4.8%) were diagnosed as having recurrent cancer, which was confirmed by clinico-radiological examination or re-operation. The risk factors that determined the recurrence patterns were investigated by using univariate and multivariate analyses. RESULTS: The mean time to recurrence was 30.9 months, and hematogenous recurrence was the most frequent type (32.0%). Among the 50 recurred patients, peritoneal recurrence showed the shortest mean time to recurrence (18.5+/-17.7 months). Between the recurred and the non-recurred patients, there was no statistically significant difference with respect to age, sex, operation type, tumor size, tumor location, gross appearance, or histological differentiation. However, depth of invasion (submucosal invasion) and nodal involvement were significantly different (P<0.001) between the two groups. Using logistic regression analyses, nodal involvement was the only significant risk factor for recurrence in early gastric cancer (P<0.001). The median survival after the recurrence had been diagnosed was 4 months. CONCLUSION: Although the prognosis for EGC patients is excellent and recurrence of EGC after a curative resection is rare, the time to recurrence and the patterns of recurrence in EGC patients were diverse and unpredictable, and the result after recurrence is dismal. Considering the impact of lymph node metastasis on recurrence of EGC, a systematic lymphadenectomy, rather than limited surgery, should be performed if lymph node involvement is confirmed pre- or intraoperatively. Also if the postoperative pathologic findings reveal lymph node involvement, adjuvant chemotherapy is recommended.

PURPOSE: There has been considerable controversy over the prognosis of gastric signet ring cell carcinoma (SRC). To clarify the biologic behavior of SRC, we evaluated the clinicopathologic features and the prognosis of SRC. METHODS: A total of 3,104 patients with a gastric carcinoma who had undergone a gastrectomy from 1987 to 1995 were analyzed retrospectively. Among them, 556 patients with SRC were compared to 2,548 patients with non-SRC. RESULTS: Patients with SRC were younger than those with non-SRC, and female were prevalent. Incidence of EGC were higher in patients with SRC. EGC with SRC had a larger proportion of mucosa-confined lesions and a lower rate of lymph node metastasis than EGC with non-SRC. Multivariate analysis showed that SRC was a negative inde pendent risk factor for lymph node metastasis. Among advanced gastric cancers SRCs showed a higher prevalence of large-sized lesions, Borrmann type IV lesions, and advanced nodal stage, as well as a higher rate of peritoneal metastasis. The 5-year survival rate of EGC with SRC (93.8%) was higher than that of non-SRC (91.2%). However, the prognosis of advanced SRC (49.0%) was poorer than that of non-SRC (53.5%). CONCLUSION: A female preponderance, a younger age, and a higher proportion of early gastric cancer characterized the peculiar biologic behavior of gastric signet ring cell carcinoma. In addi tion, the prognosis of SRC was poor once invasion had gone beyond the submucosa. These findings suggest that signet ring cell carcinoma of the stomach should be regarded as a distinct type of gastric cancer.

The amyloidosis combined with malignant neoplasm, especially stomach cancer, is rare. We experienced a case of a 60 year-old male patient who had complained of facial and lower leg edema. The laboratory findings were consistent with nephrotic syndrome, and CEA was slightly elevated. Gastroduodenoscopy revealed early gastric cancer, which suggested that the nephrotic syndrome should be associated with neoplasm, an example of membranous glomerulonephritis. Wedge resection of stomach was done with incidental splenectomy and liver biopsy. Following microscopic examination, amyloidosis was found to be involved in the liver and spleen. Bone marrow biopsy did not show any evidence of plasma cell dyscrasia. According to the literature, neoplasm can stimulate the production or precipitation of serum amyloid A like chronic infection and inflammation. But we cannot conclude that stomach neoplasm caused secondary amyloidosis, such as renal cell carcinoma or Hodgkin disease, regarding as the possibility of coincidental amyloidosis. We report a case of amyloidosis associated with early gastric cancer, represented by nephrotic syndrome.
