Background: Cancer is the second leading cause of death worldwide and the third in Iran. Among cancers, cervical cancer is the third leading cause of death in women. Thus, recognizing the epidemiology and trends of cervical cancer can be effective for planning and policy-making. This study aims to investigate the incidence and trends of cervical cancer in Iran due to the few studies that have addressed this issue and the unclear trend for cervical cancer in Iran. Methods: This study re-analyzed existing data from the cancer data recording system in Iran during years 2003 to 2009. We used available data from the National Cancer Registry and Center for Disease Control of the Ministry of Health, Treatment and Medical Education. Stata software (version 11) was used for data analysis and the significance of the incidence trend diagram was derived with WINPEPI software. Results: Assessment of the National Cancer Registry statistics from 2003 to 2009 showed an increased trend in cervical cancer from 2003 to 2008 and a decreased trend from 2008 to 2009. During this period, there were 4273 cases of cervical cancer registered. From these, 394 cases were registered in 2003 which peaked at 907 cases in 2009. The registered cancer cases had an approximately 3-fold increase during this period. Most provinces reported an increased trend of incidence in cervical cancer. Conclusion: Based on the results of this study, the incidence of cervical cancer is increasing in Iran, especially in the central regions of the country. Therefore, considering the growing trend of cancer, we recommend early detection through screening programs, public awareness, and public training programs that particularly target high risk populations.

Background & objectives: Endometriosis is one of the causes of female infertility, but the prevalence of endometriosis is not exactly known. We conducted a systematic review and meta-analysis to provide an estimate of the prevalence of endometriosis in women considering the stage of disease, diagnostic method, geographical distribution, clinical symptoms and sample size. Methods: MEDLINE, Web of Science, Google Scholar, Scopus and Cumulative Index of Nursing and Allied Health were searched to identify peer-reviewed studies published from January 1990 to December 2018 reporting the prevalence of endometriosis. Relevant additional articles were identified from the lists of the retrieved articles. Studies with cross-sectional design were included in the meta-analysis. Results: The overall prevalence of endometriosis was 18 per cent [95% confidence interval (CI): 16-20] and the prevalence of endometriosis by stage ranged from two per cent (95% CI: 1-4) for stage 4 to 20 per cent (95% CI: 11-28) for stage 1. The prevalence levels of endometriosis in women with infertility, chronic pelvic pain and asymptomatic were 31 (95% CI: 15-48), 42 (95% CI: 25-58) and 23 per cent (95% CI: 19-26), respectively. Interpretation & conclusions: The results of this study showed that the prevalence of endometriosis in developing countries was high. Future studies are needed to explore other factors affecting the prevalence of endometriosis worldwide, which may help develop future prevention programmes. [ABSTRACT FROM AUTHOR]
