Abstract
BACKGROUND
Bone metastases (BM) are related to worse outcome in patients with neuroendocrine neoplasms (NENpts).
AIM
Assess utility of serum tumor markers (STM) for detection of BM in lung NENpts.
MATERIAL AND METHODS
Diagnostic metrics of STM, such as ferritin, carbohydrate antigens 19-9 (CA19-9), cancer antigen 125 (CA125), alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) and beta-2 microglobulin (BMG) were assessed in 62 Lung NEN patients (LNENpts), both with BM (BM-LNENpts) and without BM (non-BM-LNENpts) and 40 controls.
RESULTS
Except AFP, the mean circulating STM levels in LNENpts were significantly increased vs controls (p<0.04), but the most significant difference was in CA19-9 and CEA. BM-LNENpts exhibited an elevated level only for ferritin (n=6; 180.75±53.73 ng/ml; [182.68] compared to non-BM-LNENpts (n=56; 94.33±98.80 ng/ml; [70.35], p<0.001). Three from all used STM (ferritin, BMG and CA125) could differentiate BM-LNENpts from nonBM-LNENpts (area under the curve (AUC)=0.884 for ferritin, 0.74 for BMG and 0.658 for CA 125, p<0.05). These all three STM showed significant sensitivity (100%) by lower specificity in the detection of BM.
CONCLUSIONS
Some of the STM seem to have clinical utility for detection of BM-LNEN. The single good marker was ferritin (the high AUC, sensitivity and specificity) and fair biomarker was BMG. BM-LNENpts could be diagnosed by using CEA. The follow-up with combinations of STM (ferritin, BMG) could increase the diagnostic efficacy of BM-LNENpts. This requires further studies with larger patient groups.
