Abstract
BACKGROUND Micronutrients are important components for the homeostasis of the human body. The studies available in the literature of the subject on their impact on the risk of population diseases, including malignant neoplasms, are ambiguous. In this paper, the relationship between Cu and Zn serum levels and the occurrence of endometrial cancer have been analyzed. METHODS 306 patients (153 test group and 153 control group) matched for age were analyzed for Cu and Zn levels. Microelements levels were determined for sera collected during the hospitalization of patients by means of an inductively coupled plasma mass spectrometry. In addition, the Cu/Zn ratio in the population included in the study was analyzed. Univariable and multivariable analyzes were used to examine the relationship between the factors under study and the incidence of endometrial cancer. RESULTS Lower levels of elements were observed in the study group compared with the control group (Cu: 959.39 μg/L vs. 1176.42 μg/L, p < 0.001; Zn: 707.05 μg/L vs. 901.67 μg/L, p < 0.001). A statistically significant relationship with the occurrence of endometrial cancer was observed for Cu and Zn. The patients with the lowest Cu level had a significantly higher occurrence of endometrial cancer compared with reference tertile (OR 8.54; p < 0.001). Similarly, compared with the reference tertile, the patients with the lowest Zn levels had a significantly greater incidence of endometrial cancer (OR 15.0; p < 0.001). CONCLUSION The results of the study suggest an association of endometrial cancer occurrence with lower Cu and Zn serum levels.

Abstract
The endometrial cancer (EC)-specific Quality of Life module of the European Organization for Research and Treatment of Cancer (EORTC QLQ-EN24), was developed and validated in one study. We independently validated and assessed the psychometric properties of the instrument. Two hundred and eight women with EC before surgery, during adjuvant treatment and follow-up; in three different cancer centres completed the EORTC QLQ-C30 and the EN24. The questionnaire's completion rate was 100%, except sexuality items, that were answered by 35% of patients. All item-scale correlations for the multi-item scales exceeded the .4 criterion and correlated well with their own scale, while correlations with the other scales were low. The internal consistency of all multi-item scales were satisfactory (Cronbach's alpha coefficients ranging from .77 to .97). Discriminance for single-item scales was low. The QLQ-EN24 module discriminated well between clinically different patients, and there were no differences in quality of life questionnaire scales between patients with body mass index ≤30 when compared to those with >30. This validation study supports the reliability, as well as convergent and divergent validity of the EORTC QLQ-EN24. The module is a useful instrument for the assessment of QOL in patients with EC. However, data concerning sexuality should be interpreted with caution.
