  Purpose

RATIONALE: Lymphatic mapping may improve the ability to detect cancer of the vulva.

PURPOSE: This phase III trial is studying how well lymphatic mapping works in treating patients with stage I or stage II cancer of the vulva.

Primary Outcome Measures:
  • Predictive value of negative sentinel lymph nodes in vulvar cancer patients [ Time Frame: at time of surgery ]

Enrollment: 515
Study Start Date: December 1999
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Sentinenal lymph node mapping
Sentinenal lymph node mapping
Procedure: Sentinel lymph node mapping
Sentinel lymph node mapping

Detailed Description:

OBJECTIVES:

  • Determine the negative predictive value of a negative sentinel lymph node in patients with invasive squamous cell carcinoma of the vulva.
  • Determine the location of the sentinel node in these patients.

OUTLINE: Patients receive injection(s) of isosulfan blue into the dermis at the junction of the tumor and normal vulvar skin. Once the afferent lymphatic channel and sentinel node have been identified, patients undergo unilateral or bilateral inguinal-femoral lymphadenectomy followed by resection of the primary tumor with adequate margins. Preoperative lymphoscintigraphy is also performed.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter or until recurrence.

PROJECTED ACCRUAL: A total of 40-630 patients will be accrued for this study within 2-6 years.
