Abstract

Introduction: The objective of this research was to determine the incidence of oral cancer in Korea. Materials and Methods: The classifications of oral and maxillofacial cancer (OMFC) that we used are based on possible locations of OMFC: lip, tongue, mouth, salivary glands, tonsil, oropharynx, nasopharynx, hypopharynx, pharynx unspecified, and nose, sinuses. Results: 1) There were 2,848 OMFC cases, accounting for 1.6% of all cancers. The male to female ratio was 2.72:1. 2) The estimated crude rates (CRs) were 5.7 overall, 8.4 for males, and 3.1 for females. The age-standardized incidence rates (ASRs) were 4.6 overall, 7.3 for males and 2.3 for females. 3) The incidence of mouth cancer was highest. The mouth and salivary glands were the most frequent sites for cancer among males and females, respectively. 4) Patients who were 40 years or older accounted for 91% of OMFC cases, with the highest proportion of cases in the 60-69 year-old age group for both sexes. 5) Tongue cancer was the most prevalent OMFC overall. Nasopharyngeal cancer was highest among males, and salivary gland cancer was highest among females. 6) From 2004 to 2008, the relative 5-year survival rate of OMFC patients was 57.5%. There was a trend of increasing survival among OMFC patients during the study period. The survival rate for females (69.3%) was much higher than that for males (53.1%). Conclusion: Social and personal efforts should be required to increase the survival rates of OMFC patients and Korean national cancer management policy should establish new measures for economic and social management and support.
