Comparative study of Tc-99m and Ga-67 scintigraphy in oral squamous cell carcinoma with doubted mandibular invasion. - Mandibulectomy cases -

Mandibular Invasion Caused by Oral squamous cell carcinoma通常被roentogenography、computed tomography和magnetic resonance imaging检测到。在被检测到和/或被怀疑的恶性入侵案例中，Tc-99 m（199 m 199 m）扫描学是有用的，用于澄清肿瘤的广泛感染，当用于与Ga-67连接的时候（1989年至1997年，D1 Ga）可能的肿瘤活动的扫描评估。24名患者与口腔和/或中央方块细胞carcinoma疑似感染了Mandible were investigated with Iye D199 Iye D1 mTc和Iye D167 Iye D1 Ga scintigraphy。Tumor Were的遗址; 14个较低的银杏树， 3个灌木丛， 3个Mouth Floors， 4个Mandible的中心碳水化合物。外科手术过程包括：边缘人工神经元（n=11）、分段人工神经元神经元（n=9）和半神经元（n=4）。四个经常性患者都有两个累积的D199 m D1 Tc和D167 D1 Ga扫描前治疗。三个病人有一定的边缘性神经元，一个病人接受了半神经元性神经元。Two patients with no histological mandibular invasion had no uptake ofイD167イエD1Ga and no roentogenManagement bone absorption。Two of four patients with high accumulation of y D167 y D1Ga died of the disease.A comparative study of y D199m y D1Tc and y D167 y D1Ga scintigraphy might improve the possibility for the prediction of tumor reccurence after surgery。在补充中，这是有用的，可以确定最好的外科程序，以满足复杂性。

Mandibular invasion caused by oral squamous cell carcinoma is usually detected by roentogenography, computed tomography, and magnetic resonance imaging. In detected and/or suspected cases of invasion of the mandible, Tc-99m (ィイD199mィエD1Tc) scintigraphy is useful in clarifying the extent of the mandibular invasion of the tumor, when used in conjunction with Ga-67 (ィイD167ィエD1Ga) scintigraphy evaluation of possible tumor activity.From 1989 to 1997, twenty-four patients with oral and/or central squamous cell carcinoma suspected of invading the mandible were investigated with ィイD199ィエD1mTc and ィイD167ィエD1Ga scintigraphy. Sites of tumor were; 14 lower gingivae, 3 buccal mucosae, 3 mouth floors, 4 central carcinomas of the mandible. Surgical procedures included; marginal mandibulectomy (n=11), segmental mandibulectomy (n=9), and hemimandibulectomy (n=4). Four recurrent patients had an accumulation of both ィイD199mィエD1Tc and ィイD167ィエD1Ga scintigraphy before treatment. Three patients had undergone marginal mandibulectomy, and one patient received a hemimandibulectomy. Two patients with no histological mandibular invasion had no uptake of ィイD167ィエD1Ga and no roentogenographic bone absorption. Two of four patients with high accumulation of ィイD167ィエD1Ga died of the disease.A comparative study of ィイD199mィエD1Tc and ィイD167ィエD1Ga scintigraphy might improve the possibility for the prediction of tumor reccurence after surgery. In addition, it is useful in determing the best surgical procedure for the mandible.
