ABSTRACT
@#In 2022, the National Cancer Center (NCC) of China reported the nationwide statistics of 2016 using population-based cancer registry data from all available cancer registries in China, which was mainly about the cancer incidence and mortality. Cancer remains a major health problem currently in our country and requires long term cooperation to deal with. This article provided a key point interpretation and analysis of cancer prevalence data in China, and provided an analysis of several main risk factors for cancer, which was conducive to the development of cancer prevention and control programs in different regions.
ABSTRACT
Objective:To realize the understanding level of cancer awareness of residents in Shanxi Province, and to provide a scientific basis for cancer prevention and treatment.Methods:In April 2020, 1 897 local residents in Shanxi Province were recruited to fill in the core knowledge questionnaire of cancer prevention and treatment. The basic demographic information and the core knowledge of cancer prevention and control were collected, and the influencing factors for the understanding of the core knowledge of cancer prevention and treatment were analyzed by using multivariate logistic regression model.Results:In the survey on the awareness rate of core knowledge of cancer prevention and control among residents in Shanxi Province, 37 940 items were answered, among which 29 396 items were known, and the awareness rate of the population was 77.48% (29 396/37 940). The single-factor results showed that there were statistically significant differences in awareness rates of core knowledge of cancer prevention and treatment among the population with different gender, household registration, ethnic groups, education degree, occupation and different frequency of the health examination were statistically significant (all P < 0.05); there were no statistically significant differences in awareness rates of core knowledge among the population with different age, and smokers or non-smokers (all P >0.05).Multivariate logistic regression analysis showed that education degree of junior middle school or above ( OR = 3.412-16.767, 95% CI 1.755-32.476) and receiving physical examination once a year ( OR = 2.291, 95% CI 1.154-4.549) were the favorable factors for knowing the core knowledge of cancer prevention and treatment. Household location in rural area ( OR = 0.522, 95% CI 0.378-0.722) and non-Han nationality ( OR = 0.369, 95% CI 0.151-0.904) were the unfavorable factors for knowing the core knowledge of cancer prevention and treatment. Conclusions:The awareness of core knowledge of cancer prevention and treatment among residents in Shanxi Province is good, so it is necessary to continue to strengthen the publicity of cancer prevention and control and improve the awareness of cancer prevention and control in the future.
ABSTRACT
Objective@#To investigate the level of the core knowledge and related factors of cancer prevention and treatment among residents in the upper gastrointestinal cancer screening areas of Sichuan Province in 2018. @*Methods@#From April to May 2018, a total of 1 386 residents from Chaotian District of Guangyuan, Enyang District of Bazhong, Nanjiang County of Bazhong, Cangxi County of Guangyuan, Shehong County of Suining, Yilong County of Nanchong, Xichong County of Nanchong and Xuanhan County of Dazhou were recruited in this study. A questionnaire survey was conducted to collect basic demographic characteristics and the knowledge of cancer prevention and treatment. The level of the core knowledge of cancer prevention and treatment of different population was analyzed. A multivariate linear regression model was performed to analyze the related factors. @*Results@#In total, 80.9% (1 120) of all subjects was 25-64 years old and 48.0% (665) were male. The total number of questions answered by the subjects was 18 018, of which 12 147 were known, and the overall awareness rate among the respondents was 67.42%. The female respondents, respondentsaged 65 years old and over, with junior college education or above, and worked in government institutions had a good performance of the core knowledge (P<0.05), about 70.11% (6 571/9 373), 69.23% (387/559), 76.05% (6 327/8 320), and 77.09% (5 602/7 267) respectively. The results of multivariate linear regression showed that the older the age [β=0.871 (95%CI: 0.623-1.119)], the higher the educational level [β=0.741 (95%CI: 0.540-0.943)], the more questions respondents could know; compared with the workers in government organization and institution, workers in enterprise [β=-2.913 (95%CI:-3.499--2.327)], farming workers [β=-0.635 (95%CI:-1.175--0.095)] and other occupation people [β=-1.126 (95%CI:-1.663--0.589)] could know fewer questions. @*Conclusion@#In 2018, the level of the core knowledge of cancer prevention and treatment among residents in upper gastrointestinal cancer screening areas of Sichuan Province was relatively high. Age, education level and occupation were relevant factors.
ABSTRACT
Development of small molecule drugs is important for targeted and personalized therapy for cancers.However,it is staggering to take new compounds from the research bench to clinical trial pipelines and eventually to the clinical practice,due to the time,effort and costs.Most drugs need five years of development after discovery in the laboratory before they are ready to be tested for efficacy and safety.Compared to development of new drugs from scratch, increasing research efforts have been made to turn existing drugs to new uses to treat cancers, which may bypass years of costly work.Metformin used in cancer care is a good example of giving old drugs a new life.The activity of metformin on anti-cancer has recently drawn significant attention.Epidemiological and experimental studies have shown that metformin can cut down the incidence of cancer in diabetic patients and reduce metabolism-related cancers.Meanwhile, recent study has found metformin can induce autophagy of esophageal cancer cells by inhibiting inflammatory signaling pathway.In recent years, increasing studies have shown that metformin plays a major role in suppressing cancers via multiple mechanisms.In this mini-review,we summarize the updates of the research on metformin in cancer prevention and treatment.
