PURPOSE: Although adjuvant chemotherapy after resection of gastric cancer is a popular practice in Korea, there are still controversies about the effectiveness of the treatment. The fact that the relatively less effective drugs have been used and the rarity of large-scaled controlled studies may be partially responsible for the controversies. FP(5-FU, Cisplatin) combination is one of the most active regimen against advanced gastric cancer, consistently showing a response rate of 50~60%. We tried the FP chemotherapy as an adjuvant treatment for high-risk patients after curative resection of gastric cancer. MATERIALS AND METHODS: Between February 1992 and June 1996, 35 patients with completely resected high-risk gastric cancer(postoperative stage III or IV except thase with M1) received six courses of FP chemotherapy. Endpoints were toxicities of treatment, relapse free survival, and overall survival. RESULTS: With a median follow-up time of 17.1 months, Kaplan-Meier estimates of 2-year overall survival was 63.3% and relapse free survival estimates was 49%. There were no differences between stage III and IV patients in terms of overall survival or relapse free survival. Hematologic and non-hematologic toxicities were tolerable for most of the patients. CONCLUSION: Postoperative FP combination chemotherapy was tolerable for patients with high-risk(stage III and IV) gastric cancer. It is too early to determine the long term survival rates for this patients, but 2-year overall and relapse free survival were comparable to that of historical non-cisplatin containing regimens. Randomized phase III studies are warranted.

BACKGROUND/AIMS: A single gene mutation alone cannot explain the poor prognosis of colorectal cancer. This study aimed to establish a correlation between the expression of six proteins and the prognosis of colorectal cancer patients. METHODS: Tissue samples were collected from 266 patients who underwent surgery for colorectal cancer at our institution from January 2006 to December 2007. The expression of six proteins were determined using immunohistochemical staining of specimens. RESULTS: Cathepsin D, p53, COX-2, epidermal growth factor receptor, c-erbB-2, and Ki-67 expression were detected in 38.7%, 60.9%, 37.6%, 35.7%, 30.1%, and 74.4% of the samples, respectively. The expression of cathepsin D was significantly correlated with reduced cancer-free survival (p=0.036) and colorectal cancer-specific survival (p=0.003), but the other expression levels were not. In a multivariate analysis, cathepsin D expression was found to be an independent prognostic factor for poorer colorectal cancer-specific survival (hazard ratio, 8.55; 95% confidence interval, 1.07 to 68.49). Furthermore, patients with tumors expressing four or more of the proteins had a significantly decreased cancer-free survival rate (p=0.006) and colorectal cancer-specific survival rate (p=0.002). CONCLUSIONS: Patients with cathepsin D positivity had a poorer outcome than patients who were cathepsin D-negative. Thus, cathepsin D may provide an indicator for appropriate intensive follow-up and adjuvant chemotherapy.

OBJECTIVE: The purpose of this study was to review the incidence, types, chemotherapy regimens, operation methods, pregnancy rate and propiosis of the ov#arian malignancy under the age of twenty years old. METHODS: Retrospective reviews of the medical recordings for 22 patients with ovarian malignancy under the age of twenty years old in the Department of Obstetrics and Gynecology, Hanyang University from 1986 to 1997 were done. RESULTS: Gerin cell tumor accounts for the majority of cases (77%), whereas 5 patients(23%) belong to the common epithelial poup which were all mucinous type. Our experiences with 22 cases are as followings: 5 mucinous cystadenocarcinoma, 8 immature teratoma, 4 endodermal sinus tumor, 3 dysgernma and 2 mixed germ cell tumor. The incidence of this group was 8.2% (22/266) in all ovarian malignancy. Fourteen of them are stage I, each one is, stage II and IV, and six patients are stage III. The average age was 14.9 years old in germ cell tumor and 18.4 yems old in mucinous cystadenoearcinoma. Malignant ovarian cancer under the age of twenty can be treated with conservative surgery, followed by adjuvant chemotherapy. Commonly used chemotherapeutic regimens were VAC(Vincristine, Actinomycin-D; Cyclophosphamide), VBP(Vinblastine, Bleomycin, Cisplatin) and BEP(Bleomycin, Etoposide, Cisplatin). Second look operations were done in 11 patienth and histologic positive findings were detected in 4 of them. The length of follow-up ranged ftom 3 months to 137 months and median value was 44 rnonths. CONCLUSIONS: It is concluded that for young women who wish to preserve child-bearing capacity, regardless of the stage of the tumor, fertility preserving surgery with complete surgical staging, if necessary followed by combination chemotherapy is an appropriate treatment.

BACKGROUND: The purpose decortication is to eliminate the infection focus and to improve the decreased lung function due to chronic empyema. However, lung function is not improved in all cases. It would be clinically useful it we could predict preoperatively whether lung function would improve after decortication. The purpose of this study is to find useful indices for predicting the possible improvement of lung function after decortication. METHOD: The medical records of 37 tuberculous empyema patients who underwent pleural decortication were analyzed retrospectively from 1990 to 1996. The measurements of preoperative and postoperative forced vital capacity(FVC) were used for evaluating the effects of decortication. RESULTS: The sex ratio was 29 : 8 (male to female), and the median age was 34 years. The time interval between the formation of empyema and operation was 1 month to 30 years. Postoperative pulmonary function test was performed 5.4±2.6 months later. FVC(forced vital capacity) was significantly increased from 2.77±0.67(L) to 2.95± 0.81(L). Interestingly, postoperative pulmonary function was significantly improved in patients who were less than 40 years old, within 4 months after diagnosis of tuberculous empyema, in the group with FVC of less than 60% of the predicted value and in the absence of calcification. CONCLUSION: The improvement of lung function after decortication was expected in patients younger than 40 years old, within 4 months after diagnosis of tuberculous empyema, in the group having less than 60% of the predicted FVC, without calcification.

Liposarcoma in esophagus is rare, moreover the pedunculated form is very rare. We experienced a case of liposarcoma in a 36-year-old man who had intermittent swallowing difficulty for 7 months. Endoscopy and esophagography revealed that a smooth longitudinal tumor mass occupied the esophageal lumen. Esophagotomy and surgical excision was done. The tumor was 4 cm in length and 3 cm in average diameter with an obvious stalk measuring 3.5 cm in length and 1.5 cm in diameter. Microscopic examination disclosed a lipoma with focal ulceration and liposarcomatous change infiltrating into interstitial fibrous tissue at its distal end.

PURPOSE: The incidence of secondary malignancies in hematologic patients is known to be higher than it is in other patients. However, the characteristics of secondary malignancy and surveillance have not yet been established for colorectal cancer in leukemic patients. METHODS: From 1995 to 2007, 6,030 patients who were diagnosed with acute myeloid leukemia (AML), acute lymphoid leukemia (ALL), chronic myeloid leukemia (CML), chronic lymphoid leukemia (CLL), and multiple myeloma (MM) were enrolled in this study. Among them, 9 patients were diagnosed with colorectal cancer at St. Mary's Hospital and were analyzed retrospectively. RESULTS: Three of the 2,570 patients with AML, 1 of the 1,158 patients with CML, 2 of the 83 patients with CLL, 2 of the 422 patients with MM, and none of the 1,797 patients with ALL were found to have colorectal cancer. There were no operative mortalities, but 2 patients refused to have surgery. The ratio of observed to expected subsequent colorectal cancer in CLL was higher than it was in the other groups, indicating that the relative risk of colorectal cancer is higher in patients with CLL. CONCLUSION: Compared to the Surveillance, Epidemiology and End-Result (SEER) program at the National Cancer Institute (NCI) in the United State, we have the same high relatively risk in CLL patients. Careful attention should be paid to the possibility of colorectal cancer in CLL patients.
