Abstract

Aim: This study sought to assess the incidence of oral and pharyngeal cancer based on ICD-10 in Guilan, Iran, from 2004 to 2009.

Method: This retrospective study assessed data collected from the Iranian cancer registries and publications. The rate, age-standardized incidence, type, and location of lesions according to ICD-10 were evaluated. Annual percent changes (APC) were estimated.

Results: A total of 1533 head and neck cancers were recorded. Of them, 290 cases (185 males and 105 females) were identified with oral and pharyngeal carcinoma (ICD00-14) with a mean age of 58.92 ± 17.94 years. The most common type of cancer was oral squamous cell carcinoma (n = 156). Cancer of the oropharynx (ICD 06) and lips (ICD00) had high incidence. APC was 1.36%. ASR was 3.5 and 2.04 per 100 000 among males and females, respectively. The mean crude rate was 3.69 per 1 000 000.

Conclusion: In contrast to the global cancer statistics (ICD 00-14), Guilan showed lower incidence of oral and pharyngeal cancer during the understudy years. Oral squamous cell carcinoma was the most common type of cancer in this region.
