Abstract
Objective To analyze the clinical data of vulvar squamous cell carcinoma and discuss the related risk factors.Methods The clinical data obtained from 109 cases of vulvar squamous cell carcinoma were analyzed retrospectively.Results The most common ages of onset were 50-69 years.The course of canceration was usually 6-12 months,and most lesions occurred on the labia majora.The sizes of tumour were around 2-4 cm,and more than 90 ％ of lesions were well-differentiated squamous cell carcinomas.According to 2009 FIGO new staging of vulva cancer,more patients were reclassified as stage Ⅰ B,while patients with stage Ⅱ and Ⅲ became less.99 out of 109 patients also had nonneoplastic epithelial disorders of vulva.The lesions mostly affected the labia majora and the labia minora,and 60 ％ of them were pathologically diagnosed as lichen sclerosus.Patients with nonneoplastic epithelial disorders of vulva usually developed into vulvar carcinoma within 10-15 years.Conclusion The incidence of vulvar squamous cell carcinoma is closely related with vulvar nonneoplastic epithelial disorders of the vulva.As the chronic nonneoplastic epithelial disorders of vulva increase the risk of vulvar cancer,periodic follow-up will help its early detection. Key words: Vulvar neoplasms; Neoplasms, squamous cell; Nonneoplastic epithelial disorders of the vulva
