In the literature, studies showed that self-efficacy of cancer patients are related to their quality of life in different domains. Considering the need of a scale measuring cancer related self-efficacy in Turkish culture, the objective of the current study was to examine psychometric reliability and validity of Cancer Behavior Inventory (CBI) in Turkish cancer patients. One-hundred and twenty cancer patients participated in the study. In addition to CBI, participants were administered Beck Depression Inventory, Multidimensional Quality of Life Scale - Cancer, Ways of Coping Inventory, Life Orientation Test-Revised, and General Self-Efficacy Scale to test the validity of the adapted scale. The results showed that the CBI has a four-factor structure in Turkish culture. The internal consistency of the scale was .91 and the internal consistencies of subscales ranged between .70 and .90. The validity scores of the scale were also satisfactory. The regression analysis revealed that the CBI predicts the patients' quality of life better than General Self-efficacy Scale. CBI is a valid and reliable measure. As compared to general self-efficacy measures, CBI provides more precise information about cancer patients' QOL. The results, directions for future studies and limitations were discussed in the light of the literature.

Examination of the coping processes of caregivers of children with cancer Demirtepe Saygılı, Dilek; Bozo Özen, Özlem; Department of Psychology (2013) The general aim of the present dissertation was to examine the coping processes of the caregivers of children with cancer. It was composed of three studies, whose aims were (1) to reveal the predictors of caregiver distress by using the Transactional Theory of Coping among the caregivers of children with cancer; (2) to identify the factors associated with caregiving process from the caregiver’s perspective qualitatively; (3) to develop and implement an intervention program. Study 1 was conducted with 105 pa...
The Mechanism of anti tumorigenic effects of 15-lox-1 in colon cancer Çimen, İsmail; Banerjee, Sreeparna; Department of Biology (2012) Colorectal cancer is the 4th most widespread cause of cancer mortality. One of the pathways that are involved in the development of colorectal cancer is the arachidonic acid metabolizing lipoxygenase (LOX) pathway. Inflammatory molecules formed from this pathway exert profound effects that may exacerbate the development and progression of colon and other cancers. 15 lipoxygenase-1 (15-LOX-1) is a member of LOX protein family that metabolizes primarily linoleic acid to 13-(S)-HODE. Several lines of evidence ...
The effect of dispositional optimism on posttraumatic growth: Testing the moderator role of ways of coping between dispositional optimism and posttraumatic growth in Turkish breast cancer patients Bozo Özen, Özlem; Gündoğdu-Aktürk, Elçin (2008-06-01) The aim of the present study was to examine if coping strategies mediate dispositional optimism–posttraumatic growth relation in postoperative breast cancer patients. The data were collected from 90 patients in two hospitals. Regression analyses revealed that problem-focused coping fully mediated dispositional optimism–posttraumatic growth relation, but emotion-focused coping did not. That is, postoperative breast cancer patients who were optimistic were more likely to use problem-focused coping strategies ...
Amplification of nuclear deformation of breast cancer cells by seeding on micropattemed surfaces to better distinguish their malignancies Antmen Altunsoy, Ezgi; Demirci, Utkan; Hasırcı, Vasıf Nejat (2019-11-01) Information about the mechanical properties of cancer cells leads to new insights about their malignancy levels. The more flexible the cancer cells and their nuclei are, the more aggressive and invasive they are. Flexibility is a result of composition and properties of molecular constituents of cells and its extent is expressed by deformation. Differences in the mechanical properties could be modulated by topography and chemistry of the substrate. In this study, the main hypothesis is that the difference in...
Evaluation of an aldo-keto reductase gene signature with prognostic significance in colon cancer via activation of epithelial to mesenchymal transition and the p70S6K pathway Canli, Secil Demirkol; Seza, Esin Gulce; Sheraj, Ilir; Gomceli, Ismail; Turhan, Nesrin; Carberry, Steven; Prehn, Jochen H. M.; GÜRE, ALİ OSMAY; Banerjee, Sreeparna (Oxford University Press (OUP), 2020-09-01) AKR1B1 and AKR1B10, members of the aldo-keto reductase family of enzymes that participate in the polyol pathway of aldehyde metabolism, are aberrantly expressed in colon cancer. We previously showed that high expression of AKR1B1 (AKR1B1(HIGH)) was associated with enhanced motility, inflammation and poor clinical outcome in colon cancer patients. Using publicly available datasets and ex vivo gene expression analysis (n = 51, Ankara cohort), we have validated our previous in silico finding that AKR1B1(HIGH) ...
