【摘要】目的探讨18氟2脱氧葡萄糖(18FFDG) 正电子计算机断层显像(PET/CT)显像在评估乳腺癌术后转移灶治疗疗效中的价值。方法选取乳腺癌手术后半年至5年,PET/CT显像诊断有转移灶且经病理证实的病例16例,经3个月至1年的治疗后,再行第2次PET/CT显像,通过2次显像的对比,观察病灶的18FFDG的摄取变化及形态学的改变情况来评估疗效,并与临床症状的变化进行对照。结果 16例病例中,PET/CT显像为疗效好的12例中,临床症状均明显好转;PET/CT显像为疗效不好的3例,临床症状有2例好转,另1例无改善; PET/CT显像病灶增多、无疗效1例,此病例7个月后死亡;PET/%(14/16),阳性预测值为100%(12/12),阴性预测值为50%(2/4)。结论 18FFDG PET/CT显像在评估乳腺癌术后转移灶治疗后疗效中具有非常重要的临床价值。

The clinical value of 18F
FDG PET/CT on the assessment of breast cancer metastasis plete axillary dissection
Abstract:Objective To evaluate the clinical value of 18FFDG PET/CT imaging in the assessment of posttreatment breast cancer metastasis. Methods 16 patients with breast cancer of six months to five years after surgery were recruited in the study, which were diagnosed by PET/CT imaging as metastasis foci and confirmed by pathological examination. After treatment ranging from three months to one year, they were rediagnosed by PET/CT imaging. Both imaging results pared to observe the lesions of 18FFDG metabolism changes and the morphological changes; the result was pared with the changes in clinical symptoms. Results The PET/CT imaging of 12 out of 16 cases showed satisfactory results, the clinical symptoms were also significan
