Tumor markers were also assessed: Pro-GRP 120.80 pg/mL (normal range: <74.4 pg/mL), NSE 17.610 ng/mL (normal range: 0–15 ng/mL), CEA 3.020 ng/mL (normal range: <5.5 ng/mL), CYFRA21-1 3.150 ng/mL (normal range: <3.3 ng/mL), SCC 2.130 ng/mL (normal range: <2.5 ng/mL), CA 19-9 5.800 U/mL (normal range: <34 U/mL), CA 125 16.620 U/mL (normal range: <35 U/mL), and CA 15-3 24.980 U/mL (normal range: <25 U/mL). Here, ENO2 is linked to neoplasm.
