Abstract

Objectives.: To determine the usefulness of sentinel lymph node biopsy in early stage vulvar cancer and to assess recurrences after surgical treatment with sentinel node identification or surgical treatment without sentinel node identification. Methods.: We reviewed the records of 55 patients with early stage vulvar cancer operated on between 1995 and 2005. A prospective series of 28 patients who underwent vulvectomy and lymphadenectomy with intraoperative sentinel lymph node identification between 2000 and 2005 (SLN group) was compared with a retrospective series of 27 patients who underwent vulvectomy and lymphadenectomy without sentinel node procedure between 1995 and 2000 (non-SLN group). Patients in the sentinel node identification group underwent preoperative lymphoscintigraphy (technetium-99 colloid albumin injection around the tumor) and intraoperative mapping with isosulfan blue dye. Results.: In the SLN group, 9 tumors were T1 and 19 were T2, with a total of 40 groins dissected and 9 positive nodes in 7 patients. Sixty-two sentinel lymph nodes were detected with a mean of 2.2 sentinel nodes per patient (range 0-4). A false negative case was found. In the non-SLN group, 7 tumors were T1 and 20 were T2, with a total of 49 groins dissected and 9 positive nodes in 6 patients. Recurrence occurred in 8 patients (28.6%) in the SLN group and in 6 (26.9%) in the non-SLN group (P = 0.8). Conclusions.: Sentinel lymph node identification in early stage vulvar cancer is a feasible. Analysis of recurrence may allow considering this procedure as a possible alternative to inguino-femoral lymphadenectomy. © 2006 Elsevier Inc. All rights reserved.
