Chemotherapy, Radiation Therapy, and Surgery in Treating Patients With Locally Advanced Cancer of the Vulva
RATIONALE: Drugs used in chemotherapy such as cisplatin use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Giving chemotherapy with radiation therapy before surgery may shrink the tumor so it can be removed during surgery.
PURPOSE: This phase II trial is studying how well giving radiation therapy together with cisplatin followed by surgery works in treating patients with locally advanced cancer of the vulva.
Procedure: adjuvant therapy
Procedure: conventional surgery
Radiation: radiation therapy
|Study Design:||Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase II Trial of Radiation Therapy and Weekly Cisplatin Chemotherapy for the Treatment of Locally-Advanced Squamous Cell Carcinoma of the Vulva|
- Complete clinical and pathologic tumor response at completion of treatment [ Designated as safety issue: No ]
- Toxicity weekly during treatment then every 3 months after treatment [ Designated as safety issue: Yes ]
|Study Start Date:||January 2005|
|Primary Completion Date:||December 2010 (Final data collection date for primary outcome measure)|
- Determine the efficacy of radiotherapy and cisplatin, in terms of achieving a complete clinical and pathological response, in patients with locally advanced squamous cell carcinoma of the vulva that is not amenable to standard radical vulvectomy.
- Determine the toxicity of this regimen followed by surgery in these patients.
OUTLINE: This is a multicenter study.
Patients undergo radiotherapy daily on days 1-5 and receive concurrent cisplatin IV over 30 minutes on day 1. Treatment repeats weekly for approximately 6.5 weeks (a total of 32 fractions of radiotherapy) in the absence of unacceptable toxicity.
Six to eight weeks after the completion of chemoradiotherapy, patients with a complete clinical response may undergo incisional biopsy of the primary tumor and bilateral inguinal/femoral nodes (if the groin nodes were initially unresectable). Patients with microscopic or gross resectable residual disease may then undergo radical resection of the residual tumor. Patients with unresectable disease after the completion of chemoradiotherapy receive additional radiotherapy with 1-2 courses of concurrent cisplatin.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 25-58 patients will be accrued for this study within 1.8-2.3 years.
