Back ground and objective:We aimed to assess the cancer epidemiology with a focus on the incidence of common cancers based on data collected from pathology-based cancer registries.
Method: It was a descriptive study performed on newly diagnosed (incidence) cancer cases collected from pathology-based cancer registries in a 5-year period (2007-2011) in Abhar County, in Zanjan province, Iran. All incidence cancer data collected was 365 cases. Crude and age-standardized incidence rates per 100 000 person years were calculated for each year and both sexes. The age-standardized incidence rate (ASR) per 100 000 person years was calculated by the direct method using the Iranian population.
Results: In a 5–year period from 2007–2011, 363 cases were registered, 249 (68.6%) were males, and 114 (31.4%) were females. The mean age was 65±15.58. For all cancers, the total crude incidence rate was 492 per 100000, and the total age standardized rate was 465 per 100000. Skin (crude rate: 63 per 100000, ASR: 58 per 100000) and stomach (crude rate: 39 per 100000, ASR: 32 per 100000) cancers were the most common cancers in males, and breast (crude rate: 23 per 100000, ASR: 21 per 100000) and skin (crude rate: 20 per 100000, ASR: 19 per 100000) cancers were the most common cancers in females.
Conclusion: According to increasing the numbers of cancer cases, it is necessary to develop and implement comprehensively cancer control programs in this region. As well, the cancer registry is able to planning and evaluating cancer control programs
