Uterine and Cervical Cancer in Iran: An epidemiologic analysis of the Iranian National Population-Based Cancer Registry

 Gynecologic cancers, including neoplasms of the cervix and uterine, are the fourth most common malignancies, causing 3.46% of deaths in women aged 15 to 59.

 We aimed to report the Iranian National Population-based Cancer Registry (INPCR) results for Cervical and Uterine cancers in 2017.

 The total population of Iran in 2017 was 80881792. INPCR collected data on cervical and uterine cancer incidence from 31 provinces of Iran. In this project, we retrospectively examined all the country’s regions in terms of screening for the existence of these two cancers. The registry data bank in Iran was used.

 Overall, 3481 new cervical and uterine cancer cases were registered in INPCR, including 842 cases of cervical cancer (with a crude rate of 1.04) and 2639 cases of uterine cancer (with a crude rate of 3.26). The average age-standardized incidence rate (ASR) was 0.99 for cervical cancer and 3.29 for uterine cancer. Out of 3481 new cervical and uterine cancer cases, 2887 were registered with pathological findings and 594 without pathological confirmation. In cervical cancers, the highest rate was related to squamous cell carcinoma, with 486 cases (57.72%).

 Our results showed that Iran is a low-risk area for the incidence of cervical and uterine cancers. In this study, the highest rate of cervical cancer was related to squamous cell carcinoma, confirming previous reports. However, this rate was lower than previous studies and suggested an increase in other types of cervical cancer in Iran.
