Ovarian cancer in Lebanese women: a 12-year comparative epidemiological study and trend analysis.

Purpose: Over the last decade, Lebanon has experienced an increase in the rate of cancer patients. The aim of this study is to investigate the incidence rates of ovarian cancer in Lebanese women over a period of 12 years and to compare them to other countries.

Methods: Data were collected from the Lebanese National Cancer Registry for the time period 2005-2016 (inclusive). Data from other countries were retrieved from an online database 'Cancer Incidence in Five Continents'. The age-specific and age-standardised incidence rates (ASIR) were calculated and analysed using Joinpoint regression.

Results: Ovarian cancer ranked seventh among the commonest cancers in Lebanese women in the studied time frame. Approximately 189 new cases were reported every year, with an average age-standardised incidence rate of 7.88 (per 100,000 women). Ovarian cancer showed a significantly decreasing trend in the 12 years of study. Lebanon had one of the highest ASIR for ovarian cancer among regional countries and randomly selected countries.

Conclusion: Lebanon presented a high ASIR for ovarian cancer compared to regional countries, and was placed among the top ASIRs compared to countries worldwide. However, with the decreasing ovarian cancer trends, it is important to implement efficacious awareness in order to detect all OC cases.
