Measuring cancer prevalence in Europe: the EUROPREVAL project.   总被引:8,自引:8,他引:0  
Cancer prevalence is the proportion of individuals in a population who at some stage during their lifetime have been diagnosed with cancer, irrespective of the date of diagnosis. Cancer prevalence statistics have generally been provided by a limited number of well established cancer registries that have been in existence for several decades. The advent of systematic follow-up of life status of incident cases and the availability of new statistical methodologies, now makes it possible for registries established during the 1970s or 1980s to provide prevalence data. The main problems encountered in the estimation of prevalence are the inclusion of: (i) cases lost to follow-up; (ii) cases known only from their death certificate; (iii) cases diagnosed before the start of registration; and (iv) the treatment of multiple tumours and migrations. The main aim of this paper was to review these problems and discuss, through the experience gained with EUROPREVAL, how they can be overcome. A method is presented for the calculation of prevalence of all cancers combined in the populations covered by the 45 cancer registries participating in EUROPREVAL. Prevalence of cancer is estimated to be 2% on average, with the highest values (3%) in Sweden and the lowest in Eastern Europe, with a minimum of approximately 1% in Poland.  相似文献

A common 870G > A polymorphism in the gene for cyclin D1, CCND1, has been linked to alternative splicing and cancer susceptibility. To analyze its role for breast cancer, we determined the CCND1 genotype in 500 breast cancer patients and 500 controls. CCND1 genotype frequencies were similar among patients and controls. The CCND1 genotype was furthermore not associated with tumor characteristics. We conclude that the CCND1 870G > A polymorphism is not associated with breast cancer.  相似文献

BACKGROUND: We evaluated the association between tobacco smoking and total cancer risk among Japanese populations based on a systematic review of epidemiological evidence. METHODS: Original data were obtained from searches of MEDLINE using PubMed, complemented with manual searches. Evaluation of associations was based on the strength of evidence and the magnitude of association, together with biological plausibility as previously evaluated by the International Agency for Research on Cancer. Meta-analysis of associations was also conducted to obtain summary estimates of association. RESULTS: A total of eight cohort studies were identified. In men, all studies consistently showed a moderately increased risk of total cancer in current smokers compared with never-smokers. In women, an increase in risk was seen but was weaker than in men. The summary relative risk was estimated as 1.53 (95% confidence interval 1.41-1.65). CONCLUSION: We conclude that there is convincing evidence that current tobacco smoking moderately increases the risk ( approximately 1.5 times) of total cancer in the Japanese population compared with never-smoking Japanese.  相似文献

Annual report on status of cancer in China,2010   总被引:5,自引:0,他引:5  
Objective:Population-based cancer registration data in 2010 were collected,evaluated and analyzed by the National Central Cancer Registry (NCCR) of China.Cancer incident new cases and cancer deaths were estimated.Methods:There wvere 219 cancer registries submitted cancer incidence and death data in 2010.All data were checked and evaluated on basis of the criteria of data quality from NCCR.Total 145 registries' data were qualified and accepted for cancer statistics in 2010.Pooled data were stratified by urban/rural,area,sex,age group and cancer site.Cancer incident cases and deaths were estimated using age-specific rates and national population.The top ten common cancers in different groups,proportion and cumulative rate were also calculated.Chinese census in 2000 and Segi's population were used for age-standardized incidence/ mortality rates.Results:All 145 cancer registries (63 in urban and 82 in rural) covered a total of 158,403,248 population (92,433,739 in urban and 65,969,509 in rural areas).The estimates of new cancer incident cases and cancer deaths were 3,093,039 and 1,956,622 in 2010,respectively.The morphology verified cases (MV%) accounted for 67.11% and 2.99% of incident cases were identified through death certifications only (DCO%) with mortality to incidence ratio (M/I) of 0.61.The crude incidence rate was 235.23/100,000 (268.65/100,000 in males,200.21/100,000 in females),age-standardized incidence rates by Chinese standard population (ASIRC,2000) and by world standard population (ASIRW) were 184.58/100,000 and 181.49/100,000 with the cumulative incidence rate (0-74 years old) of 21.l 1%.The cancer incidence and ASIRC were 256.41/100,000 and 187.53/100,000 in urban areas whereas in rural areas,they were 213.71/100,000 and 181.10/100,000,respectively.The crude cancer mortality in China was 148.81/100,000 (186.37/100,000 in males and 109.42/100,000 in females),age-standardized incidence rates by Chinese standard population (ASMRC,2000) and by world standard population (ASMRW) were 113.92/100,000 and 112.86/100,000,and the cumulative incidence rate (0-74 years old) was 12.78%.The cancer mortality and ASMRC were 156.14/100,000 and 109.21/100,000 in urban areas,whereas in rural areas,they were 141.35/100,000 and 119.00/100,000 respectively.Lung cancer,gastric cancer,colorectal cancer,liver cancer,esophageal cancer,pancreas cancer,encephaloma,lymphoma,female breast cancer and cervical cancer,were the most common cancers,accounting for 75% of all cancer cases in urban and rural areas.Lung cancer,gastric cancer,liver cancer,esophageal cancer,colorectal cancer,pancreatic cancer,breast cancer,encephaloma,leukemia and lymphoma accounted for 80% of all cancer deaths.Conclusions:The coverage of cancer registration population had a rapid increase and could reflect cancer burden in each area and population.As the basis of cancer control program,cancer registry plays an irreplaceable role in cancer epidemic surveillance,evaluation of cancer control programs and making anticancer strategy.China is facing serious cancer burden and prevention and control should be enhanced.  相似文献

Helicobacter pylori is thought to be a cause of gastric cancer. Risk factors of H. pylori positivity were investigated among 4,361 public service workers in Japan. Sera and information on family history and lifestyle were collected, and H. pylori antibody was measured using the sera. Sex- and age-adjusted odds ratios of factors expected to influence H. pylori seropositivity were calculated. The factors with a significant influence were included in a logistic regression model and the final model was obtained by backward elimination. Sibship size (4 and more vs. 1), smoking habit (current vs. never), and paternal and siblings' histories of gastric diseases showed significant relationships to H. pylori seropositivity, with odds ratios (95% confidence intervals) of 1.5 (1.0–2.1), 0.8 (0.7–0.9), 1.5 (1.3–1.8) and 1.7 (1.1–2.6) respectively. However, spouse's history was not related. In the final model, sibship size and paternal history remained as positive factors, and smoking as a negative one. Contradictory results on the relationship between H. pylori status and smoking among recent studies indicate the existence of hidden confounding factors. It is suggested that infection from family members in childhood considerably affects the H. pylori status of Japanese adults, whereas infection between adults is rare.  相似文献
