Abstract

Ductal adenocarcinoma represents 90‑95% of pancreatic cancer (PC) cases and it is an aggressive disease with asymptomatic evolution at early stages, non‑specific symptoms and a typical late diagnosis with a 5‑year survival rate estimated to be 8%. A window of opportunity lies in early diagnosis as there are currently no reliable biomarkers. CA 19‑9 is one of the most frequently used biomarkers of PC, with 75 and 77.6% sensitivity (Se) and specificity (Sp), respectively, and the carcinoembryonic antigen (CEA) shows 39.5 and 81.3% of Se and Sp, respectively. A case‑control study was conducted including adult patients with a histological diagnosis of PC (n=11) without previous treatment at the Oncology Service of the CMNO‑IMSS between 2019 and 2020, and a control group of adult volunteers (n=11) who were clinically healthy or with controlled disease including hypertension, hypothyroidism and diabetes. Clinical, laboratory and sociodemographic data as well as blood, urine and saliva samples were collected following patient consent. Polyamines were quantified using high‑performance liquid chromatography with fluorescence detection, CA 19‑9 and CEA were evaluated using enzyme‑linked immunosorbent assay, and the protein expression of ornithine decarboxylase (ODC) was evaluated using western blotting. Polyamine metabolism and modulation by means of ODC were increased in the serum and saliva of patients with PC, and the expression of ODC alone was increased in peripheral blood mononuclear cells (PBMCs). The present study focused on the evaluation of putrescine, spermine, spermidine and ODC in PBMCs associated with CA 19‑9 and CEA as an auxiliary tool in PC diagnosis.
