We performed an analysis of cases of simultaneous multiple cancers discovered by FDG-PET/CT performed as a part of preoperative evaluation in patients with resectable non-small cell lung cancer (NSCLC). We conducted a retrospective review of the data of 426 patients with NSCLC who underwent surgery from 2007 to 2014.
FDG-PET revealed uptake in areas other than that of the primary tumor and regional lymph nodes in 57 of the 426 patients (13.3%). Of these, 12 patients (2.8%) were diagnosed with simultaneous multiple cancers. The sites other than the lung involved in the simultaneous multiple cancers included cancers of the thyroid (4 cases), esophagus (1 case), stomach (1 case), liver (1 case), kidney (1 case), colon (1 case), prostate (1 case), and breast (2 cases). In all cases, the other cancer was also determined to be surgically resectable.
Preoperative FDG-PET/CT is not only useful for preoperative cancer staging, but also for the detection of multiple cancers.
