Conventional radiotherapy and intensity-modulated radiotherapy in carcinoma vulva: An experience from a tertiary medical center of IndiaFinancial support and sponsorship: Nil.
Context: Vulvar cancer is one of the uncommon gynecological malignancies. Multimodality treatment with surgery, radiotherapy, and chemotherapy are required for treatment of the disease. Aims: The aim of the study was to evaluate clinical outcome in patients of carcinoma vulva, treated at our institution. Subjects and Methods: This was a retrospective-cohort study done in 50 patients with squamous cell carcinoma of the vulva, treated at our institution from January 2008 to December 2014. Data were analyzed on the basis of age, stage, type of treatment received, and treatment-related toxicity. Disease-free survival and overall survival were estimated. Statistical Analysis Used: Kaplan–Meier survival analysis and Chi-square test were used for statistical analysis. Results: Majority of the patients (52%) had presented with Stage III disease. Thirty-six of 50 patients underwent surgery: simple vulvectomy – 2, radical vulvectomy – 34, bilateral inguinal lymph node dissection was done in 32 patients, and 1 patient underwent ipsilateral-inguinal lymph node dissection. Among 40 patients who received radiotherapy and eight patients received palliative radiotherapy. Seventeen patients underwent intensity-modulated radiotherapy (IMRT) and 15 patients received conventional radiotherapy. Significantly less Grade 2 or more skin toxicity (P = 0.003) observed in patients who underwent IMRT. Among non-IMRT group, eight patients required treatment break during radiation. At a median follow-up time of 25.5 months, median overall survival was 31 months and median disease-free survival was 25 months. About 42% patients were alive and free of disease at last follow-up. Conclusions: Modified radical vulvectomy with inguinal lymph node dissection followed by radiotherapy is the mainstay of management of locally advanced carcinoma vulva. Using IMRT, we could minimize the treatment related radiation toxicity and treatment breaks.
