Background: Lung cancer (LC) is one of the most common cancers around the world and evaluation of the incidence of this cancer is important for a better planning. In spite of various studies, there is no general estimate of LC incidence in Iran. Therefore, the present study is conducted to evaluate the incidence rates of LC in Iran.
Methods: A systematic search was conducted on all published studies of lung cancer incidence using Medline/PubMed, Scopus, Web of Sciences, Google Scholar, and four Iranian databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) until July 2017. This systematic review was done according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA).
Results: A total of 14 studies were included. Age-standardized rates (ASRs) of lung cancer were 6.33, 95% CI (5.24 to 7.42) for males and 2.57, 95 % CI (2.07-3.07) for females based on the random effect model.
Conclusions: Compared to other geographical locations, the incidence of lung cancer appears a little lower in Iran. However, organized system for collecting data of cancer is required to specify the incidence and trend of lung cancer in Iran.
