Objective(s): The aim of this study was to review treatment and outcomes of patients with primary vaginal cancer treated with definitive radiotherapy. Materials and Methods: We retrospectively reviewed medical records of 71 patients with primary vaginal adenocarcinoma or squamous cell carcinoma treated with definitive radiotherapy with at least 2 years of follow-up (median follow-up, 6.24 y). Results: Ninety-three percent of patients were treated with externalbeam radiotherapy plus brachytherapy (median dose, 7540 cGy); 4 patients with stage I disease and 1 patient with stage II disease were treated with brachytherapy alone (median dose, 6000 cGy). The causespecific 5- and 10-year survival rates, respectively, were 96% and 96% for stage I patients, 75% and 68% for stage II patients, 69% and 64% for stage III patients, and 53% and 53% for stage IVA patients. The 5- and 10-year local-regional control rates for all patients were 79% and 75%, respectively. The 5- and 10-year distant metastasis-free survival rates for all patients were 87% and 85%, respectively. Sixteen patients had tumors involving the distal one third of the vagina. Of the 7 who received elective inguinal node irradiation, 0 failed in the inguinal nodes. Of the 9 who did not receive elective inguinal node irradiation, 2 failed in the inguinal nodes. Severe complications (grades 3 to 4) occurred in 16 patients (23%). Conclusions: Radiotherapy provides excellent results as definitive treatment for primary vaginal cancer, although the risk of severe complications is high. Generally, treatment should consist of both external-beam radiation therapy and brachytherapy. Inguinal nodes should be irradiated electively when the primary tumor involves the distal one third of the vagina. © 2014 Wolters Kluwer Health, Inc. All rights reserved. Source

Purpose To evaluate the long-term effectiveness of radiotherapy (RT) in the treatment of sinonasal undifferentiated carcinoma (SNUC). Materials and methods The medical records of 23 patients treated with definitive or postoperative RT between 1992 and 2010 at the University of Florida were retrospectively reviewed. Fifteen patients (65%) received primary surgery and postoperative RT. Radiation doses ranged from 59.0 to 74.8 Gy (median, 70.2 Gy). The median follow-up time for all patients was 3.0 years (range, 0.9-19.9), and for living patients was 7.7 years (range, 2.5-19.9). Results The actuarial 5-year survival outcomes were as follows: progression-free survival, 42%; cause-specific survival, 43%; and overall survival, 32%. Actuarial 5-year disease control rates were as follows: local control (infield or marginal), 74%; local-regional control (excluding leptomeningeal spread), 58%, regional control 78%, freedom from leptomeningeal recurrence, 72%, and distant metastasis-free survival, 73%. Five of the 8 (62.5%) patients treated with definitive RT died with disease, and 6 of the 15 patients (40%) treated with primary surgery and postoperative RT died with disease. Three patients (13%) experienced severe complications including unilateral eye removal, osteoradionecrosis of the maxilla requiring hyperbaric oxygen and surgery, and brain necrosis. One patient died due to an infected bone graft and brain abscess. Conclusions A multimodal approach is best when treating SNUC patients. The prognosis for patients treated with definitive RT ± chemotherapy is less promising than for those who receive surgery and postoperative RT ± chemotherapy. Severe complications occur in about 17% of patients due to the high dose of RT alone or combined with surgery required for acceptable disease control. © 2014 Elsevier Inc. Source
