BackgroundVulvar cancer is one of the rare gynecologic malignancies. Despite the recent increasing trend of vulvar cancer in western countries due to the increased infection of human papillomavirus, there has been no study for population-based incidence of vulvar cancer in Korea. We aimed to investigate the prevalence and treatment of vulvar cancer in South Korea between 2014 and 2018.MethodsData from patients diagnosed and treated with vulvar cancer between 2014 and 2018 were obtained from the Health Insurance Review and Assessment Service/National Inpatient Sample (National In-Patient Sample) in South Korea.ResultsA total of 4,636,542 women were identified through the HIRA-NIS database from 2014 to 2018, of which 259 patients were diagnosed and treated for vulvar cancer. The mean age diagnosed with vulvar cancer was 62.82 (± 14.30) years in 2014, 64.19 (± 16.79) years in 2015, and 67.40 (± 14.41) years in 2016. In terms of treatment modalities, the most frequent treatment was surgery only without chemotherapy or radiation therapy. In the age-specific prevalence analysis, vulvar cancer was the most prevalent among those over 70 years old. According to multiple regression analysis, patients' age was significantly associated with the prevalence of vulvar cancer. Vulvar cancer was more prevalent in women with low socioeconomic status (SES) compared to those with high SES in 2018 (OR, 4.242; P < 0.001).ConclusionConsidering the high prevalence of vulvar cancer in the elderly, it is necessary to establish a new strategy for early screening and treatment.© 2022 The Korean Academy of Medical Sciences.
