Value of Gallium -67 scanning in differentiation of malignant and benign tumor in oral and maxillofacial area

目的 研究67镓显像在口腔颌面部良恶性肿瘤鉴别诊断中的应用价值。方法 41例口腔颌面部肿瘤患者术前行67镓局部显像 ,术后病理检查结果与之对照。结果 恶性肿瘤 2 1例中67镓显像阳性 2 0例 ,阳性率 95 .2 3% ;良性肿瘤 2 0例 ,阳性 3例 ,占 15 .0 0 %。两者差异有高度显著性(P <0 .0 0 1)。

Objective To evaluate Gallium 67 scanning in differentiation of malignant and benign tumor in oral and maxillofacial region. Methods 41 patients with tumors in the oral and maxillofacial region were undergone Gallium 67 scanning. The results were correlated with the final pathologic diagnosis.Results Twenty out of 21 patients who had malignant tumors showed positive Gallium 67 scanning images (95.23%); three of 20 patients who had benign tumors also demonstrated positive results (15.00%). There was a significant difference between these two groups ( P <0.001). Conclusions Gallium 67 scanning is a useful adjunct tool for differentiation of malignant and benign tumors in oral and maxillofacial region.
