Abstract To analyze the prognostic value of clinical-radiologic staging, morbidity, mortality and results of treatment used in the Instituto Nacional de Cancerologia, Mexico, a retrospective study of angiofibroma was performed. Charts were reviewed from patients who attended the institute from 1977 to 1993. History and physical examination, rhinoscopy and fiber-optic nasopharyngolaryngoscopy were done in every patient. Radiologic evaluation was done with computed tomography, after which Chandler's staging system was used. Disease-free interval curves were estimated for patients who had presented with stage III or IV tumors. Thirty-one patients were treated with surgery and/or radiotherapy. Most of the patients had stage III (70.9%) or stage IV (25.8%) disease. Surgical procedures included lateral rhinotomies (15 cases), transpalatal dissections (11 cases), transantral degloving (3 cases), median rhinotomies (2 cases), infratemporal transzygomatic dissections (2 cases), frontotemporal craniotomy (I case) and suprahyoid pharyngotomy (I case). Radiotherapy (as 3000–5500 cGy) was administered to 16 patients: 7 patients with stage III persistent or recurrent tumor and 8 patients as initial treatment for stage IV disease. The disease-free interval of patients with stage III and IV disease was 80.3% and 19%, respectively, after 36 months of follow-up. Findings demonstrated that surgery was the treatment chosen in patients with stage II and III disease, with low morbidity and mortality, and good results in disease control. In contrast, radiotherapy was usually the treatment in stage IV disease, but had low effectiveness, indicating the need to carefully investigate the value of craniofacial approaches in these tumors.
