Abstract OBJECTIVE: The objective of this study was to examine SLN evaluation alone in women with squamous cell carcinoma (SCC) of the vulva and evaluate the inguinal recurrence and complication rates. METHODS: An IRB approved prospective study enrolled patients with SCC of the vulva. Peritumoral injection of Tc-99 sulfur colloid and blue dye was used to identify SLNs intraoperatively. Patients with negative SLN for metastasis were followed clinically without further treatment. Patients with metastasis to a SLN underwent full groin node dissection followed by standard treatment protocols. RESULTS: A total of 73 women were enrolled onto protocol with 69 patients undergoing SLN dissection. Mean age was 66.9years (range: 29-91) with 47 stage I, 12 stage II, 9 stage III, 2 stage IV and 3 unstaged patients. SLN dissections were successful in 63 patients. Of the 111 groins evaluated with a SLN dissection 93\% had a SLN identified with an average of 2 SLN per groin. There were 92 groins with negative SLN and 11 groins with positive SLN. 57 patients had negative SLN and underwent conservative management with the median follow-up of 58.3months. Three patients experienced groin recurrences (2 unilateral, 1 bilateral) for a recurrence rate of 5.2\% (3/57). The complication rate for the inguinal incisions was 17.5\% (1 cellulitis, 1 abscess, 2 lymphoceles, 5 lymphedema and leg pain). CONCLUSIONS: Isolated SLN dissection alone has a low inguinal recurrence rate with decreased complications and should be considered as an option for women with SCC of the vulva. Copyright © 2014.
