Abstract

 
Objective: Squamous cell carcinoma (SCC) is a life threatening lesion but there has been only limited research about its frequency in Iran. The aim of this study was to evaluate the frequency of squamous cell carcinoma of the head and neck in the records of the pathology department of Imam Khomeini hospital in Ahvaz between 2005 and 2015. Methods: The retrospective and cross-sectional study was conducted using 55,708 medical records of cancer throughout the body, accumulated in the pathology department of Imam Khomeini in Ahvaz in the designated period. Information about age, gender, site of involvement, histological characteristics, status of lymph node metastasis, smoking habit, family history, job and education level was extracted and data were analyzed with the Chi-square test with SPSS version 22. Result: Of the total of 55,708 records, 582 patients (1.04%) had head and neck squamous cell carcinomas. The male to female ratio was 2.85. The frequencies in the head, mouth and neck were 28.7%, 22% and 49.3% respectively. Significant relationships between being male and location (neck) (p = 0.002), age (60 to 80 years old) and being a farmer (p = 0.001) was observed. The most important correlated risk factors were: smoking, sunlight exposure, rural residence, job and education level. Conclusion: Head and neck squamous cell carcinomas were found to account for 1.04% of all cancers in Ahvaz, one of the southern provinces of Iran.
