Abstract In this study, we evaluated the effects of marsupialization in treating unicystic ameloblastoma (UA) and investigated the relationship between TP53 and interleukin 1 &agr; (IL-1&agr;) expression and the clinical outcome of UA treated with marsupialization. Consecutive patients treated with marsupialization and curettage at Shanghai Ninth People's Hospital were included. According to the unified standard, 48 patients were included in this study. Of these, 20 showed a good response, 10 a partial response, and 18 no response, based on the outcome of the marsupialization procedure. The expression of proteins TP53 and IL-1&agr; was detected with immunohistochemistry (IHC). The clinical and pathological characteristics of the patients were analyzed. Analysis of the clinical and pathological characteristics showed that the effects of marsupialization treatment were significantly associated with lesion location (P < .001) and tumor diameter (P = .01). IHC showed that TP53 expression was significantly higher in the good-response group than in the partial- or no-response group (P = .02), and IL-1&agr; expression was significantly higher in the good-response group than in the partial- and no-response groups (P = .03). Marsupialization is an effective preliminary procedure for treating UA before curettage and peripheral ostectomy. The expression of the TP53 and IL-1&agr; proteins correlates directly with the outcome of UA treated with marsupialization.
