Because of the presence of mesenteric adenopathy and concern about a malignant process, tests for tumor markers revealed a mildly elevated CA-125 at 199.5 units/mL (normal range 0–35 units/mL) and an elevated alpha fetoprotein (AFP) at 13.67 ng/mL (normal range 0–5.63 ng/mL). This evidence concerns the gene AFP and neoplasm.
