Ten-year Survival of Corpus Uteri Cancer Patients in Urban Communities of Three Cities in Liaoning Province / 肿瘤防治研究

Objective To analyze 10 years survival status of urban female patients with corpus uteri cancer and its influencing factors in Liaoning Province. Methods Based on Liaoning cancer register database, 426 patients with corpus uteri cancer in Shenyang, Anshan and Benxi from 2000 to 2002 were randomly selected. They were followed up passively and actively. Life table method and Ederer Ⅱ method were used to calculate the observed survival rate (OSR), the expected survival rate (ESR) and the relative survival rate (RSR). Results We finally included 218 corpus uteri patients. The diagnosis proportions of stage Ⅰ-Ⅳ were 59.2%, 11.5%, 11.0% and 8.7%, respectively. Ten-year RSR and OSR were 59.6% and 67.9%. The diagnosis stage was negatively correlated with 10-year RSR. The 10-year RSR of patients treated with surgery was 71.3%, which was 6.6 times that of non-surgical treatment (10.8%). The 1-year RSR to 10-year RSR ranged from 88.4% to 67.5%. The RSR of each stage was Ⅰ-Ⅱ(95.7%-77.9%) > Ⅲ (71.4%-44.5%) > Ⅳ (58.4%-11.0%). Multivariate Cox model analysis showed that age > 55 years old, late diagnosis stage and non-surgical treatment were the main factors affecting the 10-year survival rate. Conclusion Early diagnosis and surgical treatment can significantly improve the long-term survival rate of patients. Therefore, we should strengthen the early detection and treatment of corpus uteri cancer, standardize and strengthen the screening program.

Survival of Cancer Patients in Northeast China: Analysis of Sampled Cancers from Population-Based Cancer Registries / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The cancer survival was characterized by following up sampled subgroups of cancer cases from three population-based cancer registries in Northeast China. MATERIALS AND METHODS: Survival analysis was used to analyze 6,871 patients, who had one of the 21 most common cancers based on sampling from the population-based cancer registries of three cities in Liaoning Province. All patients were diagnosed between 2000 and 2002 and were followed up to the end of 2007 by active and passive methods. The 5-year age standardized relative survival rates (ASRS) were estimated for all cancers combined and each of the 21 individual cancers. RESULTS: The survival status was traced for 80.8% of 8,506 sampled cancer cases. The 5-year ASRS for all 21 cancers combined was 41.5% (95% confidence interval, 40.3 to 42.7), the highest ASRS was observed for thyroid cancer (85.2%), breast cancer (78.9%), uterine corpus cancer (75.9%), and urinary bladder cancer (70.2%); the lowest 5-year ASRS was noted in pancreatic cancer (8.8%), liver cancer (11.0%), esophageal cancer (18.8), and lung cancer (19.6%). The cancer survival rates in Liaoning cities were similar to those of urban areas in mainland China, but significantly lower than those in Hong Kong, Korea, and Japan. CONCLUSION: The strikingly poor cancer survival rates in three cities of Liaoning Province and in other places in China highlight the need for urgent investment in cancer prevention, early detection, and standardized and centralized treatment.

Study on high incidence of hepatitis C and its epidemiological features in Jianping county, Liaoning Province / 中华传染病杂志

Objective To investigate the significantly elevated incidence of hepatitis C and mortality of cirrhosis and hepatocellular carcinoma (HCC) in Jianping county, and to explore the epidemiological features. Methods The data from database of death registry and infectious disease surveillance in Jianping county, Liaoning Province were analyzed. The distributions of incidence of hepatitis B and hepatitis C, mortality of cirrhosis and HCC in 23 villages and towns were investigated.Spearman's correlation was used to explore the correlations between hepatitis, cirrhosis and HCC.Results The standardized mortality of HCC in males and females in Jianping county were 77. 6/10~5and 22. 0/10~5, respectively, which were 2. 0 and 1. 7 times, respectively of the average levels of Liaoning rural areas. The incidence of hepatitis C was 58. 0/10~5 , which was 9. 5 times of the averagelevel of Liaoning Province. There were positive correlations between incidence of hepatitis C and mortality of cirrhosis (r=0. 495, P = 0. 008), and mortality of cirrhosis and HCC (r=0. 646, P<0.01). Conclusions The incidence of hepatitis C and mortality of cirrhosis and HCC in Jianping county are significantly higher than the average levels of Liaoning Province. Further investigations of the suspected causes are needed.

Survey of influence factors and tactics for appropriate health technology extension and ability of rural doctors in Liaoning province / 中华医学科研管理杂志

Objective To know the ability of rural health doctors, find out the scope of job satis-faction and desire of training and extending for chosen extending rural health doctors. Methods Various factors were analyzed, which affect the appropriate health technology extension in rural areas based on the study in Liaoning province with the method of the questionnaire and the categorical data statistics. Results The quality of medical human resources in rural area was low. The main influencing factors for training were practicality of the training, rescannable time and whether increasing income. Meanwhile, The appropriate health technology extension was affected by the rationality, validity, safety of techniques, acceptance degrees of patients as well as the individual professional basis. Conclusion It was necessary to focus on continued medical education to improve the rural doctor's ability. Some tactics was also put forward to promote the technology extension effect. This study provided some suggestions which could be used as references for the government making decision.

Effects of Air Pollution on Respiratory System of Children in Anshan City / 环境与健康杂志

Objective To study the adverse effects of outdoor air pollution on children's respiratory system health in Anshan city. Methods 1951 children were randomly selected from three areas with different degree of air pollution in Anshan city. The parents of the children were asked to answer a questionnaire about their children's respiratory health and home environment. The data of health were collected included persistent cough, persistent phlegm, asthma, current asthma, wheeze, and wheeze symptom. Results The prevalence rates of persistent cough, persistent phlegm, asthma, current asthma, wheeze and wheeze symptom were 9.48%, 4.82%, 1.33%, 0.92%, 6.30% and 4.97% respectively. Outdoor air pollution was a risk factor for persistent cough and persistent phlegm. The respiratory symptoms increased as the house became near to the main traffic lines. Combined effect of susceptible factor and outdoor air pollution was obvious, the prevalence rates of respiratory diseases were higher in the susceptible children who were influenced by the other risk factors compared with those who were not influenced by the same factors. Conclusion Outdoor air pollution is an important factor which will damage children's respiratory system in Anshan city.
