ABSTRACT
OBJECTIVE:
To determine whether an intraoral stent may decrease radiation dose to health tissues during intensity-modulated radiotherapy (IMRT) and to evaluate the effect on mucositis. STUDYDESIGN:
A total of 33 patients with tongue or floor of the mouth cancer were retrospectively evaluated and divided into 2 groups group 1 (with stent, n = 19) and group 2 (without stent, n = 14). Data were collected on dosimetric and mucositis outcomes.RESULTS:
The mean dose to the maxilla was significantly lower in group 1 (20.9 Gy) than in group 2 (35.8 Gy) (P = .05). The mean dose to the ipsilateral parotid was 35.0 Gy in group 1 vs 41.8 Gy in group 2 (P = .05). No difference was seen in the severity of mucositis between groups (P = .82). However, grade III mucositis was present in group 1 at 4 weeks after IMRT, 1 week after its occurrence in group 2.CONCLUSIONS:
A stent was effective in decreasing doses to healthy structures and delaying the emergence of mucositis.
