PURPOSE: This study was performed to investigate the effects of environmental factors, genetic polymor phisms of cytochrome P450 2E1 (CYP2E1) and N-acetyltransferase 2 (NAT2), and their interactions on mutations of p53 and Ki-ras genes in Korean stomach cancer. METHODS: One hundred nine stomach cancer patients and 211 age- and sex-matched controls were enrolled in this study. Direct interview with a structured questionnaire was performed to get informations on the level of exposure to environmental factors. For genotyping of the metabolic enzymes, PCR-RFLP methods were used. RT-PCR and direct sequencing were carried out to detect mutations in the p53 and the Ki-ras genes of stomach cancer tissue. To evaluate the risk of stomach cancer, we calculated odds ratios for environmental and genetic factors, and their combinations. RESULTS: Past medical histories of gastritis, diabetes and asthma allergic rhinitis were significant risk factors for stomach cancer. Fried potatoes, squid and octopus, welsh onions and chestnuts and gingkonuts had protective effects against stomach cancer. On the contrary, chicken, soybean paste stew, and soybean milk were significantly related to an increased stomach cancer risk. The NAT2 rapid acetylator turned out to be a marginally significant risk factor for gastric cancer. Mutations of the p53 and the Ki-ras genes were detected in 27.5% and 10.7% of stomach cancer tissues, respectively. Frizzled rice, potato, beef, lard, pickled fish, chicken stew, anchovies, tempura, Welsh onions, eggs, bean-curd, Qing-style soybean paste stew, and ice cream were protective against p53 mutation whereas yogurt was a risk factor for p53 mutation in stomach cancer tissue. Ki-ras mutation was associated with less intake of pears and persimmons, melons, strawberries, grapes and milk and with more intake ofsoybean paste stew. In a multiple logistic analysis including genetic polymorphism, past medical history and diet intake, past history of gastritis, chicken, soybean paste stew, and soybean milk were significant risk factors for stomach cancer whereas past history of diabetes, squid and octopus, and Welsh onions were protective factors against stomach cancer. CONCLUSION: These results suggest that past medical history and diet are more important risk factors for stomach cancer than genetic polymorphism and that mutations of the p53 and the Ki-ras genes would be induced by the respective risk factors.

OBJECTIVE: To understand the pathogenesis of adenomyosis through the immunohistochemical staining with bcl-2 and matrix metalloproteinase-9 (MMP-9) antibody. METHODS: We selected 45 cases of adenomyosis among the uterine specimens that were extirpated surgically due to benign gynecologic problem. Immunohistochemical staining to the myometrial tissue was performed using anti-bcl-2 and anti-MMP-9 antibodies. Staining was qualitatively assessed in terms of extent and intensity. RESULTS: There were 32 cases of proliferative phase and 13 cases of secretory phase depending on the date of endometrium. Anti-bcl-2 stained 81.3% (26/32) compared with anti-MMP-9 stained 6.3% (2/32) in the glandular tissue of the proliferative phase (p<.001). In the secretory phase, anti-bcl-2 92.3% (12/13) and anti- MMP-9 7.7% (1/13) respectively (p<.001). In the stromal tissue of the proliferative phase, anti-bcl-2 stained 62.5% (20/32) compared with anti- MMP-9 stained 6.3% (2/32) (p<.001). In the secetory phase, anti-bcl-2 84.6% (11/13) and anti-MMP-9 15.4% (2/13) (p<.001). CONCLUSION: The adenomyosis may be developed from simple invagination and cellular proliferation of endometrial tissue, not caused by myometrial infiltration of endometrial tissue.

PURPOSE: The liver and lung are the most common site of metastases after curative resection of colorectal carcinoma, and only 10 months of median survival is achieved once metastases has occurred in the lung. About 10% of patients have a solitary pulmonary metastasis and surgical resection leads to a 5 year survival rate of 21~43%. We have tried to define ideal candidates for pulmonary resection in a patient with pulmonary metastases from colorectal carcinoma. METHODS: Between March 1990 to Feb. 2001, 25 patients underwent pulmonary resection for metastatic colorectal carcinoma. 15 patients were male, and 10 were female with mean age of 60.0 (range, 36~73) years. The primary sites were colon in 7 patients and rectum in 18 patients. RESULTS: The mean disease free interval was 30.04 19.79 (range, 1~84) months and 19 patients had single metastasis and 6 patients had multiple metastatic lesions. Twenty- one patients had unilateral lesion. Wedge resection was done in 10 patients, lobectomy in 7, pneumonectomy in 2, wedge resection with bilobectomy in 2, segmentectomy and wedge resection in 1, and segmentectomy and lobectomy in 1 patient. Six patients recurred mean 13.7 months after the first operation (range, 1~33 months) and they underwent wedge resection in 4 and one case each of lobectomy and segmentectomy. Seven patients died during follow up with 3 year survival rate of 70.8% and 5 year survival rate of 43.4%. CONCLUSIONS: The disease free interval, number of metastases, type and location of pulmonary resection, level of carcinoembryonic antigen had no correlation with the survival rate. We conclude that surgical resection of colorectal lung metastases is safe and effective, and every patients should be evaluated as a surgical candidate.

BACKGROUND & AIMS: Management of ovarian carcinoma presents most commonly by surgery and subsequent platinum-based chemotherapy, but most patients will have either residual or recurrent disease. Taxol, a new antimicrotubule agent, has been indicated as a salvage measure after failure of first-line or subsequent chemotherapy. The purpose of this study is to investigate the efficacy and toxicity of Taxol used as a salvage therapy. MATERIALS & METHODS: Between January 1994 and Jun 1996, 19 patients aged 38-64 years(median 52) with ovarian carcinoma were given Taxol-containing regimen. Taxol was administered at a dose of 135mg/m2 intravenously with cisplatin or carboplatin every 3 weeks. The patients who treated with Taxol only were received 175mg/m2 intravenously with same interval. The median treatment cycle was 6.6 cycles(range, 3 to 15 cycles). Patient's response were evaluated with tumor marker(CA-125) and CT or MRI before and after chemotherapy. Responses and toxicities were defined according to the Gynecologic Oncology Group criteria.

Even though malignant potential of vaginal intraepithelial neoplasia(VaIN) may be low, the prevalence is increasing and the mean age at diagnosis is decreasing. Various treatment options have been used for the eradication of ValN, but most effective standard protocol is not present because it is a rare disease. Laser vaporization was used to treat 7 patients with VaIN diagnosed at Department of Obstetrics and Gynecology, Seoul National University Hospital between 1992 to 1996. The patients were from 40 to 70 years of age with a mean 57 of years. All patients had a history of radical or simple hysterectomy, and final pathologic diagnosis were as follows : cervical cancer(n=5), cervical intraepithelial neoplasia(n=l), leiomyoma(n=l). Vaginal intrae-pithelial neoplasia(VaIN) was identified between 4 months and 8 years after first operation. All lesions were unifocal disease and found at the upper one third of the vagina. Treatment was performed with a CO2 laser unit and colposcope. Four(57%) out of seven patients had general anesthesia for the purpose of treatment. Patients were followed up for an average of 16.8 months with regular cytologic evaluation, colposcopy and biopsy. Failure of therapy was defined as evidence of intraepithelial neoplasia in any one of these three parameters. Only one patients showed persistent disease and the others remain free of disease. The success rate of therapy was 85.7%(6/7). (continue)
