Ipsilateral superficial inguinal lymphadenectomy for the treatment of early cancer of the vulva.
OBJECTIVE
This study compared the rates of survival, recurrence, and the occurrence of complications after surgery for vulvar cancer in selected patients treated by simple vulvectomy or wide local excision (WLE) and ipsilateral superficial inguinal lymphadenectomies (ISIL) and who were in a representative group of previous patients treated by standard radical surgery (control).


METHODS
Superficial inguinal lymphadenectomies were performed in 32 patients with laterally localized squamous cell tumors of 1 to 3 cm in size and without palpable lymph nodes. Eight cases, which showed histological evidence of lymph node metastasis, were submitted to conventional radical treatment and excluded from the study. Of the remaining 24 patients, 12 underwent vulvectomy, 7 hemivulvectomy, and 5 WLE. The results of this group were compared with those of 21 historical controls who previously had tumors of 1 to 3 cm and had been treated by radical vulvectomy with superficial and deep bilateral inguinal lymphadenectomy.


RESULTS
Dehiscence of the flaps occurred in 66.6% of the control patients and in 8.3% of the ISIL group (chi , p <.0001). There was lymphedema in 13.8% of the controls and none in the ISIL group (Fisher exact test, p <.02). Upon follow-up (3 to 8 years, results are reported for 3 years of follow-up), there were 9.5% vulvar recurrences in the controls and 12.5% in the ISIL group (Fisher exact test, p <.652 not significant).


CONCLUSIONS
WLE and deep local excision of the primary lesion and ISIL in selected patients with early vulvar cancer seems to be a safe alternative to the traditional radical method.
