INTRODUCTION
The solitary keratocystic odontogenic tumor (KCOT) is a neoplasm, which recurs in 28% of cases. The purpose of this study is to determine whether clinicoradiographic features can predict recurrence.
MATERIAL AND METHODS
From 2000 to 2009, 106 solitary KCOTs were retrieved from the Oral Biology Service of British Columbia. Among 58 KCOTs including all recurrent KCOTs (rKCOT) and nonrecurrent KCOTs (nrKCOT) (followed up for at least 5 years), only 29 had radiographs (rKCOT, 18; nrKCOT, 11).
RESULTS
Patients with recurrences were significantly older than those without. Interestingly, those cases, which were considered KCOTs before surgery, were significantly more likely not to recur within 5 years of follow-up. Most radiological features did not differ between nrKCOT and rKCOT on the basis of panoramic radiography only.
简介
孤立性角化囊肿型牙源性肿瘤（KCOT）是一种易复发的肿瘤，其复发率为 28%。本研究旨在确定临床影像学特征是否可预测复发。
材料与方法
2000 年至 2009 年，从不列颠哥伦比亚口腔生物学服务处检索到 106 例孤立性 KCOT。在 58 例 KCOT 中（包括所有复发性 KCOT[rKCOT]和非复发性 KCOT[nrKCOT]），只有 29 例有 X 光片（rKCOT 18 例，nrKCOT 11 例）。
结果
复发患者明显比未复发患者年龄大。有趣的是，那些术前被认为是 KCOT 的病例，在 5 年的随访期内，其复发的可能性显著降低。仅基于全景 X 光片，nrKCOT 和 rKCOT 在大多数影像学特征方面没有差异。
