Background: Oral cancer stands among the 10 top causes of cancer death in the world. Considering the role of epidemiologic information on planning and effective interventions, the present study aimed to investigate the epidemiology of oral cancer in Iran. Materials and Methods: The required information for this systematic review study was obtained from PubMed, Google Scholar, CINAHL,SID, Medlib, Magiran and Iranmedex databases, using key words "cancer", "oral cancer", "squamous cell carcinoma", "oral cavity carcinoma" and their Persian equivalents in combination with keywords of epidemiology, prevalence, etiology, frequency, and Iran from 1990 to 2014. From 1,065 related studies found, finally 25 were included to the study. Results: The mean age of 8,248 patients in 25 studies was 54.0±15.1 years. The male/female ratio for oral cancer was 1.91. Tongue with average percentage of 29.9 was the most involved site. Regarding microscopic grade, 65.7% of cases were grade 1. SCCs, accounting for an average of 70.0%, was the most common among all types of oral cancer. In the majority of studies, smoking including cigarette, hookah, and tobacco consumption was found to be a risk factor. Conclusions: The epidemiological pattern of oral cancer in Iran is somewhat similar to that of other countries. Yet the information on hand in this field is limited and considering the role of epidemiological data we suggest conducting more accurate studies to catch data that is required for effective programs and interventions.

Introduction: Genital infection with papilloma virus is the most common sexually-transmitted disease (STD). It is recommended that individuals who have a sexual risk factor, should be screened for syphilis, human immunodeficiency virus (HIV), and hepatitis B and C. However, this strategy is often not carried out in Iran. In the present study, patients with genital warts were screened for syphilis, HIV, and hepatitis B and C. Methods: We evaluated 311 patients with anogenital warts visiting dermatology clinics from June 2016 to June 2017. In addition, demographic data were collected using a pre-designed questionnaire. Patients who presented to Sina Hospital, Tabriz, Iran, were examined for HIV, syphilis, hepatitis B and C, urethral and vaginal discharge, and history of painful genital lesions, while patients presenting to Bahar Behavioral Disease Counseling Center of Tabriz were examined only for HIV. Data were analyzed using chi-square and Fisher’s exact tests via SPSS software. Results: Out of 263 cases with genital warts presenting to Sina Hospital, 1, 1, and 2 cases were positive for HIV, syphilis, and hepatitis B, respectively. At the same time, one of the patients presenting to Bahar Center showed HIV infection. Conclusion: We found two HIV-positive, two hepatitis B virus (HBV)-positive, and one syphilis cases in 311 patients with genital warts, so it is recommended to assess these tests routinely in high-risk individuals with genital warts, including multi-partner and addicted patients.
