Objective-Describe the treatment and survival patterns among a population-based sample of vulvar cancer patients diagnosed in the U.S. in 1999.Methods-Cases were identified for the National Cancer Institute's Patterns of Care Study (POC) using Surveillance, Epidemiology, and End Results Program (SEER). A stratified random sample of non-Hispanic white, non-Hispanic black, and Hispanic women age 20 and older was selected from cases reported by eleven SEER registries. Analyses of the association between vulvar cancer and key demographic, clinical, and hospital characteristics by stage were performed. Cox proportional hazards was used to estimate the odds of death due to cancer. All estimates were weighted, and analyses were conducted with SUDAAN.Results-90% of cases were diagnosed with in situ or early stage invasive disease. Older patients were more likely to present at advanced stages. 25% of women with Stage III-IV vulvar cancer received chemotherapy plus radiation. We noted widespread use of radical local excision among women with Stage I/II cancer, but 46%-54% with invasive disease underwent a radical or total vulvectomy. Factors associated with cancer death were limited to age and stage. Women 75 years and older were at higher risk compared to women aged 20-49 and the risk of death increased with advancing stage.Conclusions-Vulvar cancer is diagnosed at early stages. Late stage disease is associated with a significant increase in mortality. Radical surgery was still commonly performed in 1999. Radiation was more common in women diagnosed at late stage, while the use of chemoradiation remained limited.
