In unresectable patients, radiotherapy is a therapeutic option for local control. Our aim in this study was to analyze the clinical benefit and local control provided by two modalities of radiotherapy: the Three-Dimensional Conformal (3DC) technique and volumetric modulated arc therapy (VMAT), applied to pediatric patients with JNA considered unresectable and non-recurrent. Methods: In retrospective study, the information was recorded from pediatric patients with a diagnosis of non-recurrent and unresectable JNA treated with radiotherapy at the Oncology Hospital of the National Medical Center SXXI of Mexico City, from March 2010 to March 2021. Radiotherapy management and its association with clinical outcomes of tumour control, and symptoms were assessed. In addition, an evaluation of acute and chronic toxicity was performed. Results: It was found that the median age was 14 years. 9 patients (37.5%) underwent 3DC and 15 (62.5%) VMAT. In terms of local control, and progression-free survival, we did not find significant difference between radiotherapy modalities (p ≤ 0.57). Acute toxicity for both modalities presented statistical differences for radio epithelitis (p = 0.03). Only Grade I and II radiation-induced acute toxicity was observed. Regarding chronic toxicity, statistical significance was observed for craniofacial hypoplasia, in relation to its absence in the VMAT group (p = 0.001). Conclusion: The VMAT presents improvements in dosimetry parameters that improve patient toxicity. In both techniques adequate tumour control was observed, however, the rarity of the disease is a limitation to establish the most appropriate therapeutic technique.展开更多

Methods： Superselective angiography was done via femoral. TAE with polyvinyl alcohol particles and/or gelfoam （GF） was performed in 12 patients with nasopharyngeal angiofibroma. All patients underwent surgical removal of devascularized tumors in 3 to 7 days after TAE. Results： During digital subtraction angiography, tumor staining was seen in 12 patients. Embolization of maxillary artery was performed in 12 cases and additional embolization of ascending pharyngeal artery in 8 cases. Conclusion： Superselective angiographic diagnosis, embolization and appropriate embolic particle size are important for successful treatment of nasopharyngeal angiofibroma. TAE is safe and effective in decreasing haemorrhage during surgical operation for nasopharyngeal angiofibroma.展开更多
