The Association Between Serum Dickkopf-1 Levels and Esophageal Squamous Cell Carcinoma
(Sage Publications Ltd, 2014) Begenik, H.; Kemik, A. S.; Emre, H.; Dulger, A. C.; Demirkiran, I.; Ebinc, S.; Kemik, O.
Serum Dickkopf-1 (DKK-1) is elevated in many malignancies and is an important indicator of malignant potential. However, its significance in esophageal squamous cell cancer (ESCC) has not yet been clarified. We hypothesized a role for DKK-1 in patients with ESCC. The study consisted of 90 ESCC patients and 85 healthy controls. After diagnosis, the level of DKK-1 was measured in the serum samples by enzyme-linked immunosorbent assay and the levels of DKK-1 were much higher in the ESCC patients than in the healthy control group (p < 0.0001). For serum DKK-1, the sensitivity and specificity of the assay were 70 and 80%, respectively. The preoperative serum DKK-1 level was elevated in the ESCC patients. Although serum DKK-1 is not a specific biomarker for ESCC, it might be a useful marker for the diagnosis and treatment of ESCC.

The Prevalence of Helicobacter Pylori in Patients With Oesophageal Stenosis
(Malaysian Soc Parasitology Tropical Medicine, 2018) Yilmaz, O.; Temur, A.; Almali, N.; Dulger, A. C.; Sasmaz, M., I
Oesophageal strictures often occur following esophagectomy which is performed for cases of oesophageal cancer. These patients require repeated dilation procedures. The aim of this study is to investigate the effects of dietary regimens, which are changed because of stenosis, caused by Helicobacter pylori (H. pylori). In this retrospective study, 28 patients who had operation for oesophageal cancer and underwent dilation due to development of stricture were studied. 30 female and 30 male patients who were admitted to the Gastroenterology Clinic with complaints of dyspepsia and did not receive treatment for the eradication of H. pylori were randomly selected and included in this study as a control group. Patients' histopathological records on the hemogram, biochemistry, and endoscopic biopsy were analysed. There were 26 H. pylori (+) cases (92.8 %) in the stenosis group consisting of 28 patients, and 37 H. pylori (+) cases (61.6%) in the control group consisting of 60 patients. These results were found to be statistically significant (P=0.003). The albumin level in the stenosis group was reported to be statistically low (P=0.002). The incidence of H. pylori was found to be significantly higher in patients with stenosis. We ascribed this outcome due to changes in dietary regimens. Our findings showed that the dietary regimens of all patients who underwent esophagectomy should be regulated during the postoperative period considering H. pylori. The relationship between H. pylori and stenosis was significant, there is a need for further research with a larger sample size to enrich the findings.
