Abstract
PURPOSE
This study was coducted to describe the epidemiological, characteristics of the outbreak of cholera of overseas travelers on Aug. 2005 in Daejeon. MATERIALS AND METHODS: Interview using a standard questionnaire and rectal swab were conducted to 15 overseas travelers ,27 persons who contacted with travelers RESULTS: Epidemiological characteristics of the 2005 cholera epidemic of Daejeon are as follows: 1. Isolated species were Vibrio cholerae, O1 El Tor Ogawa. There were 6 culture-proven patients, 4 culture-not proven patients and 2 asymptomatic carriers. There was no case of person to person infection and no fatal cases 2. The sex distribution of cholera patients was equal. The most of cholera patients were at the age of fifties. 3. The duration of diarrhea was 4.4 days. The number of diarrhea per 1day was 5.5. 4. Source of Vibrio cholerae in this outbreak was suggested to be the contaminated food from the overseas traveling to epidemic area, Mandalay, Myanmar on Aug. 8, 2005 CONCLUSIONS: It is recommended that the government should be prepared to prevent cholera of overseas travelers effectively. To prevent the outbreak of cholera by chronic carriers, we need to strengthen the monitoring sytem of diarrhoeal diseases.

Abstract
PURPOSE
This study was carried out to investigate survival rate and the factors affecting survival among lung cancer patients who have been registered in Daejeon Cancer Registry from 1998 to 2000.
METHODS
Kaplan-Meier method and Cox proportional hazard model were used to evaluate the factors affecting survival of lung cancer patients.
RESULTS
Lung cancer was more common in men than women, with an overall sex ratio in Daejeon, Korea of roughly 3:1. The incidence of lung cancer was 17.1 per 100,000 population in 1998, 21.4 in 1999, and 22.4 in 2000. Average age of incidence was 64.8 years old and 11.7% of study subjects having family history of lung cancer. Forty eight % of lung cancer was diagnosed as Stage III and 40.6% as Stage IV. Histologically, squamous cell carcinoma was 39.7% of all and most frequent, and then adenocarcinoma 25.5%, and small cell carcinoma 19.3%. 3-year survival rate of female was higher than that of males, and that of smoker was the lowest among groups according to the smoking level. Survival rate by age fell dramatically in group over 70 years. Lung cancer patients diagnosed as Stage III and Stage IV had a much lower survival rate than those diagnosed as Stage I or II. Stage, LDH and age were proved to be important variables that affect the mortality of lung cancer patients.
CONCLUSION
We found that the stage at diagnosis was a critical factor that affected the survival of lung cancer patients from this study. So It is essential to develop early diagnosis of lung cancer and then it needs to evaluate the effectiveness of that.

Abstract
PURPOSE
This study was conducted to investigate case-fatality rates and survival rates, prognostic factors of prevalent five cancers(stomach, lung, liver, cervix, colon) in a university hospital located in Taejon City.
METHODS
2,158 cancer patients who have admitted the hospital from Jan. 1, 1991 to Dec. 31, 1998 were analysed. The higher ratio of outbreak and growing were selected among the investigated cancer data for over 100 of subjects in Korean cancer patient was examined into two method. The one is medical record and the other is affirm a government office for existence or not.
RESULTS
The lung cancer was discovered for the highest fatality rate. The crude 5-year survival rate of all cancer patients was 43.9% and that in male was higher than that in female. The 5-year survival rate of stomach cancer patients were 49.7%, that treated with combined(operation and chemotherapy) were 66.2%, that with metastasis to lymph node were 48.1%, and distant metastasis were 31.9%. Lung cancer patients were 25.9%, that treated with operation were 42.7%, and that with metastasis to lymph node were 29.3%. Hepatoma patients were 25.5%, that treated with operation were 37.8%. Uterine cervix cancer patients were 74.8%, that treated with operation were 95.0%, that with metastasis to lymph node were 83.3%, and distant metastasis 74.8%. Colon cancer patients were 41.8%, that treated with operation were 50.2%, that with metastasis to lymph node were 33.4%. Prognostic factors affecting survival rate among stomach cancer patients were age, operation, operation with cancer chemotherpy, and metastais to lymph node and distant matastasis. Prognostic factors of uterine cervix cancer was age, and that of colon cancer were operation with radiotherapy, metatasis to lymph node and distant metastasis.
CONCLUSION
case-fatality rate in male were higher than that in female, and increased with age. The cancer survival rate of female is high, the high in over 40 years group, and operation is exposed in the highest survival rate, also significant difference in metastasis level.

Abstract
This study presents the comparative pattern of risks for cancers of the breast, uterine cervix and ovary in relation to various risk factors based on the data from a case-control study conducted at the Korea Cancer Center Hospital in Seoul between August in 1996 and March in 1997. Included in the analysis were 128 women of breast cancer, 169 women of uterine cevical cancer and 45 of ovarian cancer confirmed by the historical diagnosis. Person interviews were conducted in all cases through standard questionnaire. Data were analyzed using multiple logistic regression, adjusting for potential confounding factors. In cancers of the uterine cervix and ovary, increasing risks were seen in earlier age at first menarch. Statistically significant associations were found with postmenopausal women in cancers of the breast(OR=2.0) and ovary(OR=8.5). The OR increased with late age at postmenopause in postmenopausal women of uterine cervical cancer(OR=7.0). Increasing number of pregnant and livebirths was associated with a higher risk of uterine cervical cancer(OR=2.7, 2.9). The risk of uterine cervical cancer was decreasing with increasing age at first birth(OR=0.2). Among postmenopausal women, the OR increased with BMI in breast cancer. A positive history of breastfeeding was associated with significantly lower risk of breast cancer(OR=0.4). There were no associations with anthropometric measurements(height, weight, BMI), smoking, alcohol intake, menstrual regularity, age at first marriage, number of marriage and induced abortion, and oral contraceptives in cancers of the breast, uterine cervix and ovary. In cancers of the breast and uterine cervix, decreasing risks were seen in intake of fresh fruits, carrot and cabbage.
