目的探讨18氟代脱氧葡萄糖(~(18)F-FDG)符合线路单光子发射计算机化断层显像(SPECT)CT显像在肺癌术后随访中的应用价值。方法选取2012年3月至2013年5月间德阳市人民医院收治的56例行肺癌根治术的肺癌患者,以术后病理结果为金标准,评估~(18)F-FDG符合线路SPECT/CT显像在肺癌患者术后随访中的应用价值。结果残端复发、残端复发合并转移、单个病灶、多发转移及胸部未见明显复发转移征象患者例数分别为14、9、4、13和12例。~(18)F-FDG符合线路SPECT/CT显像诊断肺癌术后复发灵敏度为93.2%(41/44),特异性为75.0%(9/12),准确性为83.9%(47/56),阳性预测值为93.2%(41/44),阴性预测值75.0%(9/12)。结论~(18)F-FDG符合线路SPECT/CT显像在肺癌患者术后随访诊断复发价值较高,为临床医师制定辅助化疗方案提供重要参考。
Objective To investigate the value of 18 Fluorodeoxyglucose (~ (18) F-FDG) line coincidence single photon emission computerized tomography (SPECT) CT in postoperative follow-up of lung cancer. Methods Fifty-six patients with lung cancer undergoing radical resection of lung cancer who were treated in Deyang People’s Hospital from March 2012 to May 2013 were enrolled in this study. The postoperative pathological results were taken as gold standard to evaluate the value of ~ (18) F-FDG coincidence SPECT / CT Application of imaging in postoperative follow-up of lung cancer patients. Results The number of patients with stump recurrence, stump recurrence and metastasis, single lesion, multiple metastasis and no obvious recurrence and metastasis in chest was 14, 9, 4, 13 and 12 cases respectively. The sensitivity and specificity of ~ (18) F-FDG coincidence SPECT / CT imaging in diagnosing lung cancer were 93.2% (41/44), 75.0% (9/12), and 83.9% (47/56) , The positive predictive value was 93.2% (41/44), the negative predictive value was 75.0% (9/12). Conclusions ~ (18) F-FDG coincidence SPECT / CT imaging in the diagnosis and treatment of lung cancer patients with follow-up diagnosis of relapse is of high value, providing an important reference for clinicians to develop adjuvant chemotherapy regimens.
