Primary vaginal cancer treated with concurrent chemoradiation using Cis-platinum

Purpose: To evaluate the feasibility of concurrent weekly Cis-platinum chemoradiation (CRT) in the curative treatment of primary vaginal cancer. Methods: A retrospective review was performed of all primary vaginal cancer patients treated with curative intent at the Ottawa Hospital Regional Cancer Centre between 1999 and 2004 using concurrent Cis-platinum CRT. Results: Twelve patients were treated with concurrent weekly CRT. The median age at diagnosis was 56 years (range, 34-69 years), and the median follow-up was 50 months (range, 11-75 months). Ten patients (83%) were diagnosed with squamous cell carcinoma and 2 patients (17%) with adenocarcinoma. The distribution according to stage was as follows: 6 (50 %) Stage II, 4 (33 %) Stage III, and 2 (17 %) Stage IVA. All patients received pelvic external beam radiotherapy (EBRT) concurrently with weekly intravenous Cis-platinum chemotherapy (40 mg/m(2)) followed by brachytherapy (BT). The median dose of EBRT was 4500 cGy given in 25 fractions over 5 weeks. Ten patients received interstitial BT, and 2 patients received intracavitary BT, with the median dose being 3000 cGy. The 5-year overall survival, progression-free survival, and locoregional progression-free survival rates were 66 %, 75 %, and 92 %, respectively. Late toxicity requiring surgery occurred in 2 patients (17 %). Conclusions: For the treatment of primary vaginal cancer, it is feasible to deliver concurrent weekly Cisplatinum chemotherapy with high-dose radiation, leading to excellent local control and an acceptable toxicity profile.
