Abstract
PURPOSE: The purpose of this study was to elucidate our experience in the diagnosis and treatment of adenoid cystic carcinoma of the vulva (ACC-vulva) and to assess the clinicopathological characteristics and prognosis among ACC-vulva patients. METHODS: A retrospective study of seventeen patients was performed to illustrate the demographic information, clinical performance, pathological characteristics, treatment modality, and development of local recurrence or distant metastasis, as well as the survival outcome. RESULTS: The median age at diagnosis was 56 years (range, 26-71 years). Radical local excision was performed on fifteen patients, and two patient received radical hemi-vulvectomy. Six patients received ipsilateral inguinal lymphadenectomy. Involvement of the resection margin was observed in six patients. The postoperative pathologic diagnosis showed no proof of inguinal lymph node metastasis in all the six patients receiving lymphadenectomy. However, the perineural invasion was observed in all patients. Postoperative adjuvant radiotherapy was applied to five patients who had positive resection margin. The mean survival time except for that in four patients (recent case) was 47.8 months (range, 23-78 months). CONCLUSION: Radical resection towards negative margins seems to be acceptable as initial treatment. Adjuvant radiotherapy is a preferable treatment modality for patients with high-risk factors pathologically or patients with local recurrence.
