Background: Breast cancer is typically detected in women with a standard prevalence categorized by age of 80.1/100.000 people in the world. In Vietnam, the proportion for women was 17.4/100.000 people in 2000. The value of ultrasound has been acknowledged in the last few decades. However, there is an existing problem related to the proportion of inaccurate diagnosis (amounted to 10-20%), or suspect diagnosis. Thus, the diagnosis of breast cancer employing ultrasound (US) method not only overcomes the above obstacles, but also generates a number of advantages. \r\n', u'Objectives: To study the value of US and US lesions in the diagnostic for breast cancer. \r\n', u'Subjects and method: 621 patients with breast abnormalities were diagnosed and treated at K-hospital from 2003 to 2006. They underwent breast US scanning. The sonographic features were compared with pathologic results. \r\n', u'Results: Common signals of breast cancer: the mass of irregular shape: Se = 73.9%, Sp = 87; speculation margins: Se = 72.4%, Sp = 96.8%; hypoechoic mass: Se = 89.5%, Sp = 83.3%; heteroechoic density: Se = 98%, Sp = 68.5%. Other uncommon signals are: punctuate hyperechogenics of calcifications, acoustic shadow behinds the mass, the number of punctuate hyperechogenic > 5. The D/W index > 1: PPV = 95.9%. \r\n', u'Conclusion: Ultrasound is a valuable method for breast cancer diagnosis with Se = 89.47%, Sp = 86.49%, PPV = 92.96%, NPV = 83.72% and Acc = 88.41%.\r\n', u'

PURPOSE: Rates of women with breast cancer have increased rapidly in recent years in Vietnam, with over 10,000 new patients contracting the disease every year. This study was conducted to identify demographic, reproductive and lifestyle risk factors for breast cancer in Vietnam. MATERIALS AND METHODS: Breast density, demographic, reproductive and lifestyle data of 269 women with breast cancer and 519 age-matched controls were collected in the two largest oncology hospitals in Vietnam (one in the north and one in the south). Baseline differences between cases and controls in all women, premenopausal and postmenopausal women were assessed using chi-squared tests and independent t tests. Conditional logistic regression was used to derive odds ratios (OR) for factors that had statistically significant associations with breast cancer. RESULTS: Vietnamese women with breast cancer were significantly more likely to have a breast density > 75% (OR, 1.7), be younger than 14 years at first menstrual period (OR, 2.2), be postmenopausal (OR, 2.0), have less than three pregnancies (OR, 2.1), and have less than two babies (OR, 1.7). High breast density (OR, 1.6), early age at first menstrual period (OR, 2.6), low number of pregnancies (OR, 2.3), hormone use (OR, 1.8), and no physical activities (OR, 2.2) were significantly associated with breast cancer among premenopausal women, while breast density (OR, 2.0), age at first menstrual period (OR, 1.8), number of pregnancies (OR, 2.3), and number of live births (OR, 2.4) were the risk factors for postmenopausal women. CONCLUSION: Breast density, age at first menarche, menopause status, number of pregnancies, number of babies born, hormone use and physical activities were significantly associated with breast cancer in Vietnamese women.

Background: Coordinating between soldiers and people bring significant results in protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Objectives: To evaluate epidemic supervision and propose solutions protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Subjects and methods: A retrospective cross sectional study was carried out on two provinces Binh Phuoc and Dak Lak\r\n', u'Results: there was 4 main disease types were fever, tuberculosis, diarrhea and malaria. Malaria at investigated times still accounted high rate comparing with general fever rate. Malaria risk contained in people living or working in forest and mountain field; free emigrants; armed forces and border guard. These subjects needed to improve regularly protection from malaria. Communication of health education is one of important method to prevent and control malaria.\r\n', u'Conclusion: It is necessary to implement strong methods (such as providing insecticide treated bed nets, indoor residual spray) to prevent and control malaria. \r\n', u'
