    Circulating annexin A2 as a biomarker in patients with pancreatic cancer
    (WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2020-01-01) Karabulut, Mehmet; Afsar, Cigdem Usul; Serilmez, Murat; Karabulut, Senem
    Background: Pancreatic cancer (PC) is a highly lethal malignancy. There are only few predictive or prognostic markers for PC. This study was conducted to investigate the serum levels of annexin A2 (AnxA2) in patients with PC and its relationship with tumor progression and known prognostic parameters. Materials and Methods: Serum samples were obtained on the first admission before any treatment. Serum AnxA2 levels were determined using enzyme-linked immunosorbent assay. Age- and sex-matched healthy controls were included in the analysis. All statistical tests were carried out using two-sided test, and P <= 0.05 was considered statistically significant. Results: The median age at diagnosis was 59 years. The most common metastatic site was liver in 23 patients with metastasis (n = 19, 83\%). At the end of the observation period, thirty-two patients (97\%) were dead. Thirty-nine percent of 23 metastatic patients who received palliative chemotherapy (CTx) were CTx responsive. Median overall survival of the whole group was 41.3 +/- 8.3 weeks (95\% confidence interval = 25-58 weeks). The baseline serum AnxA2 levels were significantly higher in patients with PC than in the control group (P = 0.01). Serum AnxA2 levels were significantly higher in the patients with high erythrocyte sedimentation rate (P = 0.04). Conversely, serum AnxA2 concentration had no prognostic role on survival (P = 0.18). Conclusions: AnxA2 is identified as a novel secretory biomarker for PC, but it has no role as a prognostic or predictive marker.

    Clinical Significance of Serum NEDD9 Levels in Patients with Pancreatic Cancer
    (MDPI, 2018-01-01) Afsar, Cigdem Usul; Karabulut, Mehmet; Karabulut, Senem; Ozal, Safiye Tokgoz; Cikot, Murat; Serilmez, Murat; Tas, Faruk
    Introduction: Pancreatic cancer (PC) is a lethal malignancy. Various diagnostic, predictive, and prognostic biomarkers have been evaluated. This study was conducted to investigate the serum levels of neural precursor cell expressed developmentally downregulated protein 9 (NEDD9) in patients with PC and the relationship between tumor progression and known prognostic parameters. Materials and Methods: Serum samples were obtained on first admission before any treatment. Serum NEDD9 levels were determined using enzyme-linked immunosorbent assay (ELISA). Age- and sex-matched healthy controls were included in the analysis. Results: In a three year period, 32 patients with a pathologically-confirmed diagnosis of PC were enrolled in this study. The median age at diagnosis was 61 years, range 38 to 84 years
