Abstract
Purpose To evaluate treatment outcomes with image-guided brachytherapy (IGBT) for distal vaginal and vulvar cancers. Material and methods Women treated for distal vaginal or vulvar malignancies utilizing IGBT were retrospectively reviewed, and acute and late toxicities were retrospectively graded. Descriptive statistical analysis was performed. Results Eighteen patients were included, out of which, twelve patients (66.7%) were with primary disease of the distal vagina and vulva, most commonly squamous cell carcinoma of the vulva (n = 8, 66.7%), and six with recurrent disease, most commonly recurrent endometrial carcinoma (n = 5, 83.3%). All patients received external beam radiation (EBRT) to a median dose of 45 Gy in 25 fractions, followed by IGBT (range of 15 to 27.5 Gy in 3 to 5 fractions). Mean follow-up was 20.6 months. Mean dose to high-risk clinical target volume (HR-CTV) D90 was 72.4 Gy. Mean D2cc for the rectum, bladder, and urethra were 50 Gy, 50.6 Gy, and 62.9 Gy, respectively. Five patients (27.8%) recurred. Three patients (16.7%) had local recurrence, 1 patient (5.6%) had distant recurrence only, and 1 patient (5.6%) had simultaneous regional and distant recurrence. Grade 3 acute toxicities included 1 (5.6%) vaginal stenosis, 6 (33.3%) dermatitis/mucositis, 2 (11.1%) vaginal pain, and 1 (5.6%) vaginal/vulvar infection. Grade 3 late toxicities comprised 3 (17.7%) cases of vaginal pain and 1 (5.9%) skin/vaginal necrosis. There were no grade 4 or higher toxicities. Conclusions Definitive radiation therapy in the form of EBRT and IGBT provides meaningful loco-regional control in women with distal vaginal and vulvar cancers, with mainly skin and vaginal toxicity.

Brachytherapy as part of the conservative treatment for primary and recurrent vulvar carcinoma. Brachytherapy 2017; 16:518-525. [PMID: 28262516 DOI: 10.1016/j.brachy.2017.01.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2016] [Revised: 12/22/2016] [Accepted: 01/12/2017] [Indexed: 11/29/2022]
Abstract
PURPOSE There are only scarce data on the place of brachytherapy (BT) for treatment of vulvar carcinoma. Our institutional experience of interstitial BT for vulvar carcinoma patients is reported. METHODS AND MATERIALS Clinical records of patients receiving low-dose-rate or pulsed-dose-rate BT as part of the primary treatment for primary/recurrent vulvar squamous cell carcinoma or as part of postoperative treatment between 2000 and 2015 were included. Patients, tumors, and treatment characteristics as well as clinical outcome were examined. RESULTS A total of 26 patients treated with BT were identified. BT was delivered as part of primary intent treatment for locally advanced/recurrent cancer in 11 patients and as part of postoperative treatment in 15 patients. Median age at time of BT was 63 years (range, 41-88 years). Pulsed-dose-rate and low-dose-rate were used in 15 patients and 11 patients, respectively. BT was performed as a boost to the tumor bed following external beam radiotherapy (n = 13) or as the sole irradiation modality (n = 13). Total median dose at the level of primary tumor was 60 GyEQD2 (range, 55-60 GyEQD2). With mean followup of 41 months (range, 5 months-11.3 years), 11 patients experienced tumor relapse, and in two of them, site of relapse was only local. Three-year estimated disease-free survival and overall survival rates were 57% (95% confidence interval: 45-69%) and 81% (95% confidence interval: 72-90%), respectively. All toxicities were Grade 2 or less. CONCLUSIONS Interstitial BT used as part of the primary or postoperative treatment of vulvar carcinoma is feasible with a satisfactory toxicity profile. Prognosis remains, however, dismal, with a high frequency of failures in patients with locally advanced tumors.
