Completeness of cancer registry data in a small Iranian province: A capture–recapture approach

Background and Objective: The incidence of cancer is rising in Iran, and hence it is important to assess the accuracy of the Iranian cancer registry dataset. In this study, the completeness of the cancer registry in the Kohgiluyeh and Boyer-Ahmad (K&B) province is evaluated. Method: The data of registered cases of cancer of people who were living in the K&B province at the time of diagnosis were obtained from the provincial cancer registry offices in K&B, Fars and all other neighbouring provinces. A capture–recapture method along with log-linear statistical modelling were used for analysis. Results: The results indicated that of 2029 known cases of cancer, only 1400 (31%) were registered by the K&B cancer registry office. Age-adjusted incidence rates for all common types of cancer rose from 307.0 per 100,000 (95% confidence interval (CI); 293.8, 320.3, based on observed cases) to 376.4 per 100,000 (95% CI; 361.7, 391.1, based on expected number of cases estimated by capture–recapture analysis) ( p < 0.01). The completeness of cancer registry data varied significantly for different types of cancer. Conclusion: Results suggest that the provincial cancer dataset, which is a part of the national cancer registry programme, is neither complete nor representative. A major improvement in case finding, registry procedures and effective data sharing by provincial cancer registry offices is needed in order to provide valid data for epidemiology of cancer in Iran.

The purpose of the study was to compare data on the cancer incidence rates for 2016 between the official reports on cancer statistics and federal cancer registry, collected in December 2018.Material and Methods. The study estimated the total data on 18 parameters from 35 regions of Russia, covering 66.3 million people (2016). The database of the Russian cancer registry and the database containing reports on the state cancer statistics were used. The cancer statistics/cancer registry ratio was assessed.Results. No differences in cancer incidence between the official reports on cancer statistics and cancer registry data were found. In the official reports on cancer statistics, the mortality rate, the proportion of posthumously recorded patients per 100 newly diagnosed, the proportion of deaths from diseases not related to cancer per 100 deceased patients, the cancer prevalence and the prevalence rate of unspecified malignant tumors were slightly reduced (to 10 %, 9 %, 5 %, and 4 %, respectively), and the rate of cancer detection, the proportion of histologically verified diagnoses and the proportion of cancers detected in stage III were increased (to 19 %, 10 % and 14 %, respectively) compared to those in cancer registry data.Conclusion. Improvement in the quality and completeness of information about cancer patients is associated rather with increasing the annual report length than with the need to improve the cancer registration system itself.

AbstractPurpose:The objective of this study was to estimate the burden of cancer in counties affected by Hurricane Katrina using population-based cancer registry data, and to discuss issues related to cancer patients who have been displaced by disasters.Methods:The cancer burden was assessed in 75 counties in Louisiana, Alabama, and Mississippi that were designated by the Federal Emergency Management Agency as eligible for individual and public assistance. Data from the National Program of Cancer Registries were used to determine three-year average annual age-adjusted incidence rates and case counts during the diagnosis years 2000–2002 for Louisiana and Alabama. Expected rates and counts for the most-affected counties in Mississippi were estimated by direct, age-specific calculation using the 2000–2002 county level populations and the site-, sex-, race-, and age-specific cancer incidence rates for Louisiana.Results:An estimated 23,549 persons with a new diagnosis of cancer in the past year resided in the disaster-affected counties. Fifty-eight percent of the cases were cancers of the lung/bronchus, colon/rectum, female breast, and prostate. Eleven of the top 15 cancer sites by sex and black/white race in disaster counties had >50% of cases diagnosed at the regional or distant stage.Conclusions:Sizable populations of persons with a recent cancer diagnosis were potentially displaced by Hurricane Katrina. Cancer patients required special attention to access records in order to confirm diagnosisand staging, minimize disruption in treatment, and ensure coverage of care. Cancer registry data can be used to provide disaster planners and clinicians with estimates of the number of cancer patients, many of whom maybe undergoing active treatment.

Abstract Objectives To evaluate how the certification of specialised Oncology Centres in Germany affects the relative survival of patients with colorectal cancer (CRC) by means of national and international comparison. Methods Between 2007 and 2013, 675 patients with colorectal cancer, treated at the Hildesheim Hospital, an academic teaching hospital of the Hannover Medical School (MHH), were included. A follow-up of the entire patient group was performed until 2014. To obtain international data, a SEER-database search was done. The relative survival of 148,957 patients was compared to our data after 12, 36 and 60 months. For national survival data, we compared our rates with 41,988 patients of the Munich Cancer Registry (MCR). Results Relative survival at our institution tends to be higher in advanced tumour stages compared to national and international cancer registry data. Nationally we found only little variation in survival rates for low stages CRC (UICC I and II), colon, and rectal cancer. There were notable variations regarding relative survival rates for advanced CRC tumour stages (UICC IV). These variations were even more distinct for rectal cancer after 12, 36 and 60 months (Hildesheim Hospital: 89.9, 40.3, 30.1%; Munich Cancer Registry (MCR): 65.4, 28.7, 16.6%). The international comparison of CRC showed significantly higher relative survival rates for patients with advanced tumour stages after 12 months at our institution (77 vs. 54.9% for UICC IV; raw p<0.001). Conclusions Our findings suggest that patients with advanced tumour stages of CRC and especially rectal cancer benefit most from a multidisciplinary and guidelines-oriented treatment at Certified Oncology Centres. For a better evaluation of cancer treatment and improved national and international comparison, the creation of a centralised national cancer registry is necessary.
