Abstract

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.

伊朗一个小省癌症登记数据的完整性：捕获-再捕获方法

背景和目的：伊朗癌症发病率正在上升，因此评估伊朗癌症登记数据集的准确性很重要。在这项研究中，评估了Kohkiluyeh和Boyer-Ahmad（K&B）省癌症登记的完整性。方法：从K&B省、Fars省和所有其他邻近省份的癌症登记处获得诊断时居住在K&B省的人的癌症登记病例数据。采用捕获-再捕获方法以及对数线性统计建模进行分析。结果：结果表明，在2029例已知的癌症病例中，只有1400例（31%）在K&B癌症登记处登记。所有常见类型癌症的年龄调整后发病率从307.0/10万上升（95%置信区间（CI）；293.8320.3，基于观察到的病例）至376.4/10万（95%CI；361.7391.1，基于捕获-再捕获分析估计的预期病例数）（p<0.01）。不同类型癌症的癌症登记数据的完整性差异显著。结论：结果表明，作为国家癌症登记计划的一部分，癌症省级数据集既不完整，也不具有代表性。为了为伊朗癌症流行病学提供有效数据，癌症省级登记办公室需要在病例发现、登记程序和有效数据共享方面进行重大改进。
