Collaboration . International collaboration patterns are visualized in Figure 1; China and Japan engaged in collaborative research recently.

Themes . Text co-occurrence analysis revealed four keyword clusters: (1) “recurrent,” “overall survival,” “median,” “feasibility”; (2) “dose distribution,” “computed tomography,” “dosimetry,” “image”; (3) “nasal vestibule,” “preservation,” “procedure,” “high dose”; and (4) “review,” “guideline,” “literature,” “application,” which seem to relate to salvage brachytherapy, 3D dosimetry, nose preservation, and guidelines development, respectively. Older publications primarily focused on clusters 1, 2, and 3, whereas recent publications were on cluster 4 (Figure 2).
