~(67)镓枸橼酸盐为一放射性同位素扫描剂,已发现各种恶性肿瘤对其有选择性摄取。正在观察~(67)镓扫描在已证实的头颈部鳞癌中的用途。在这些病人中,用~(67)镓全身扫描作为治疗前检查方法的一部分。然后与临床及手术所见相比较,以测定这种方法的正确性。本文分析25例的扫描结果,60％在原发灶处有明显的阳性摄取;但在转移性淋巴结处的摄取则很少,在18侧颈部只有6侧为阳性。1例临床检查为阴性,但镓扫描为阳性,后经手术标本的组织学检查证实为恶性病变。文内曾述及断定头颈部镓扫描结果所遇到的困难。认为经过病人的选择及改进扫描技术,可以提高这种方法的阳性率及查出恶性病变的意外扩展。
~ (67) gallium citrate is a radioisotope scanning agent, it has been found that a variety of malignant tumors its selective uptake. The use of ~ (67) gallium scans in confirmed head and neck squamous cell carcinoma is under observation. In these patients, a ~ (67) gallium full body scan was used as part of the pre-treatment test. Then compared with clinical and surgical findings to determine the correctness of this method. This article analyzes the results of 25 cases of the scan, 60% of the primary lesions were significantly positive uptake; but in metastatic lymph nodes at the intake is very small, 18 sides of the neck only 6 positive. One patient had a negative clinical examination, but a gallium scan was positive. Histological examination of the specimen was confirmed as malignant. The document addresses the difficulties encountered in determining head and neck gallium scan results. That after the patient’s choice and to improve scanning technology, can improve the positive rate of this method and detect the unexpected expansion of malignant lesions.
