“…This can affect the increase of the average incidence age in registered cases reported only by the source of death certificates to the population-based cancer registry system. Incidence in men over women was 1.99, while this ratio is different from country reports, as it has been equal to 2.59, 2.61 and 2.58 in country reports of the years of 2005, 2006 and 2007, respectively and also has been equal to 2.33 in Ardabil's population-based cancer registry report during 2004-2006(Babaei et al, 2009). These ratios show very differences in cancer incidence in male and female subgroups of the population under the coverage of Tehran Metropolitan area Cancer Registration in comparison with other country and regional reports.…”

“…Second, all people should have equal chance of entering to the sources. To reduce the problems raised from the lack of these assumptions, using of more than two sources or using of stratified methods to equalize chances of cases registration in each source are recommended (Hook and Regal, 1995;McClish and Penberthy, 2004). In this study, three sources were used to reduce the effects of these two assumptions.…”

Introduction: Capture-recapture methods have been suggested for reducing costs of disease registration as well as reducing bias in incidence estimations. This study aimed to estimate the gastric cancer incidence in theTehran metropolis population during 2002-2006. Materials and Methods: We investigated new cases of gastric cancer reported by three sources; death certificates, pathology reports, and medical records to Tehran population-based cancer registry during 2002-2006. G 2 statistics and the two-source capture-recapture method were used to select the best-fitted log-linear model and to estimate incidence, respectively. EXCEL software version 2007 and SPSS software version 16 were used for this research. Results: The number of reported cases was 4,463, with an average age of 68.5 (±12.9) years. We found the model that combined two sources of data including pathology reports and medical records and furthermore complemented by death certificates as the best model. The reported and the estimated incidences were 11.0 and 27.1 per 100,000 respectively. Conclusions: The incidence estimated by twosource capture-recapture method is about three times higher than the incidence reported by the sources under investigation. It is recommended to move towards the implementation of population-based cancer registration using various sources of data collection to achieve more accurate data. , Alireza Mosavi-Jarrahi 4 * special events. Such information is very important for policymakers and health workers (Hook and Regal, 1995; IWGDMF, 1995). Using capture-recapture methods is recommended for reducing the costs of disease registration as well as reducing bias in incidence estimations and for comparing population subgroups. Modeling the effect of intervening variables presents better estimations of population size and therefore solves many problems of the estimation of population size (Tilling, 2001).Tehran population-based cancer registry center has started since 1998. The main goal of this center is to measure cancer incidence in Tehran metropolis. Since Tehran is a referral center for all around the country, epidemiologists and experts of this center faced with the large amounts of data encountering many problems. Data collection area of this center includes Tehran metropolis plus Islamshahr and shemiranat townships (Mohagheghi et al., 2009;Aghaei et al., 2012; Haidari et al., 2012).Central areas of Iran including Tehran have the highest incidence of gastric cancer after North and Northeast regions (Kolahdoozan et al., 2010 (Mohagheghi et al., 2009). This study aims to estimate the real incidence of gastric cancer in the Tehran population. Materials and MethodsNew cases of gastric cancer that have been reported by three sources including death certificates, pathology reports, and medical records to Tehran Metropolitan Area cancer registry center during 2002-2006 years. Since Tehran is a referral center, cases not being among the areas covered by the registration center (Tehran, Islamshahr and Shemiranat townships) a...

“…These problems decrease accuracy and reliability of the estimation provided by capturerecapture method. Approach to encounter these problems is the use of more than two sources, the use of log-linear models for modeling dependencies between resources (Hook and Regal, 1995), and the use of layering methods in terms of disease behaviors and people for equalization of cases registration chance in each source (McClish and Penberthy, 2004).…”

Background: Having knowledge or estimation of cancer incidence is necessary for planning and implementation of any cancer prevention and control programs. Population-based registries provide valuable information to achieve these objectives but require extra techniques to estimate the incidence rate. The present study aimed to estimate the esophageal cancer incidence using a log-linear method based on Tehran population-based cancer registry data. Materials and Methods: New cases of esophageal cancer reported by three sources of pathology reports, medical records, and death certificates to Tehran Metropolitan Area Cancer Registry Center during 2002-2006 were entered into the study and the incidence rate was estimated based on log-linear models. We used Akaike statistics to select the best-fit model. Results: During 2002-2006, 1,458 new cases of esophageal cancer were reported by the mentioned sources to the population-based cancer registry. Based on the reported cases, cancer incidence was 4.5 per 100,000 population and this was estimated to be 10.5 per 100,000 by the log-linear method. Conclusions: Based on the obtained results, it can be concluded that an estimated incidence for 2004 of 8.3 per 100,000 population could be a good benchmark for the incidence of esophageal cancer in the population of Tehran metropolis.

“…Previous research about the potential bias caused by the length of the observation period and incompleteness of data on prevalence and incidence estimation has often focused on cancer registries and on data from a single jurisdiction. 26,27 Computer simulation and statistical modeling techniques that have been proposed to estimate or adjust for these effects 28,29 could be extended to multiple jurisdictions. Methodological investigations about the utility of other administrative databases, such as prescription drug databases, to estimate the completeness of PSDs for chronic disease surveillance 8 could also be used for comparisons across many jurisdictions.…”

Introduction Physician services databases (PSDs) are a valuable resource for research and surveillance in Canada. However, because the provinces and territories collect and maintain separate databases, data elements are not standardized. This study compared major features of PSDs. Methods The primary source was a survey of key informants that collected information about years of data, patient/provider characteristics, database inclusions/exclusions, coding of diagnoses, procedures and service locations. Data from the Canadian Institute for Health Information's (CIHI) National Physician Database were used to examine physician remuneration methods, which may affect PSD completeness. Survey data were obtained for nine provinces and two territories. Results Most databases contained post-1990 records. Diagnoses were frequently recorded using ICD-9 codes. Other coding systems differed across jurisdictions and time, although all PSDs identified in-hospital services and distinguished family medicine from other specialties. Capture of non-fee-for-service records varied and CIHI data revealed an increasing proportion of non-fee-for-service physicians over time. Conclusion Further research is needed to investigate the potential effects of PSD differences on comparability of findings from pan-Canadian studies.
