目的评价PET/CT监测结肠癌术后复发转移的价值。方法 收集结肠癌术后可疑复发转移患者78例,男46例,女32例。回顾性分析比较PET/CT、传统影像学与组织病理学诊断或临床随访资料之间的差异,并比较PET/CT与传统影像学诊断结肠癌术后可疑复发转移的价值。结果 78例中,54例经组织病理学诊断或临床随访确诊存在复发、转移。PET/CT诊断结肠癌术后总体复发转移的灵敏度及准确率明显优于传统影像学,灵敏度分别为90.74%和51.85%(P<0.01),准确率分别为89.74%和58.97%(P<0.01)。PET/CT诊断结肠癌术后局部复发转移的灵敏度及准确率亦明显优于传统影像学,灵敏度分别为90.91%和42.42%(P<0.01),准确率分别为96.15%和75.64%(P<0.01)。结论 PET/CT在诊断结肠癌术后可疑复发转移中具有较高的灵敏度及准确率,是一种较理想的监测方法。
Objective To evaluate the value of PET / CT in monitoring recurrence and metastasis of colon cancer. Methods 78 patients with suspicious recurrence and metastasis after colon cancer surgery were collected, including 46 males and 32 females. The differences between PET / CT, traditional imaging and histopathological diagnosis or clinical follow-up data were retrospectively analyzed. The value of PET / CT and conventional imaging in the diagnosis of suspected recurrence and metastasis of colon cancer was compared. Results Among 78 cases, 54 cases were diagnosed by histopathology or clinically followed up for recurrence and metastasis. The sensitivity and accuracy of PET / CT in diagnosing colon cancer recurrence and metastasis were significantly better than those of conventional imaging (90.74% vs 51.85%, P <0.01), and the accuracy rates were 89.74% and 58.97% (P <0.01) ). The sensitivity and accuracy of PET / CT in the diagnosis of postoperative local recurrence and metastasis of colon cancer were also significantly better than those of conventional imaging with the sensitivity of 90.91% and 42.42% (P <0.01), and the accuracy of PET / CT was 96.15% and 75.64%, respectively (P < 0.01). Conclusion PET / CT is an ideal monitoring method in the diagnosis of postoperative recurrence and metastasis of colon cancer with high sensitivity and accuracy.
