临床上,约50%左右的非小细胞肺癌(non-small cell lung cancer,NSCLC)患者在首诊时即发现合并有全身转移~([1-3]),已接受根治性手术切除的肺癌术后患者,也有接近30.0%~75.0%最终出现局部复发与远处转移~([4-5])。然而,并非所有的转移都是全身多发、广泛性、不可治愈的,在合并远处器官转移的NSCLC患者中,约有7.0%的患者表现为肺外孤立性转移,且相当长时间处于这种相对稳定状态~([6])。随着PET/CT、
Clinically, about 50% of patients with non-small cell lung cancer (NSCLC) are diagnosed with lung cancer who have undergone radical surgical resection at the time of first diagnosis (~ [1-3]) Postoperative patients, there are also nearly 30.0% ~ 75.0% of the final local recurrence and distant metastasis ~ ([4-5]). However, not all transfusions are systemic, extensive and incurable. Approximately 7.0% of NSCLC patients with distant organ metastases exhibit isolated solitary pulmonary metastases and are present for such an extended period of time Relatively stable state ~ ([6]). With PET / CT,
