In the present study, associations between pretreatment interleukin 6 (IL-6), interleukin 8 (IL-8) and C-reactive protein (CRP) serum levels and epithelial ovarian cancer (EOC) were analyzed using commercially available, enzyme-linked immunosorbent assay (ELISA) in 118 patients and 64 control subjects. Values were correlated with clinicopathological characteristics and outcomes. Control variables included age, stage, grade, histological type and residual tumor size. Kaplan-Meier plots and univariate and multivariate Cox proportional hazards models were used to study the associations between IL-6, IL-8 and CRP levels, control variables, overall survival and disease-free survival. The median IL-6, IL-8 and CRP serum levels in EOC were significantly higher than in the normal control group; 11.5 pg/mL (range, 3.4-62.6) versus 2.9 (1.1-12.3) pg/mL (p<0.001) and 21.8 pg/mL (range, 16.4-105.3) versus 9.3 (4.3-32.4) pg/mL (p<0.001) and 9.51 mg/L (range, 0.3-129.2) versus 1.2 (0.1-11.5) mg/L (p = 0.001), respectively. High levels of IL-6, IL-8 and CRP were associated with reduced overall survival (P = 0.003, P = 0.035, P = 0.046) and disease-free survival (P<0.001, P = 0.026, P = 0.043), respectively. Multivariate analyses showed that IL-6, IL-8 and CRP serum levels independently predicted disease-free survival (P = 0.011, P = 0.001 and P = 0.021), and overall survival (P = 0.004, P = 0.014 and P = 0.016), respectively. EOC is associated with extensive changes in the serum cytokine environment, highlighting the importance of further investigations of relative cytokine level changes. Preoperative serum IL-6, IL-8, and CRP levels seem promising for distinguishing EOC patients from healthy controls; however, their clinical value is still to be confirmed. High levels of IL-6, IL-8, and CRP in EOC patients have been suggested to be a poor prognostic factor for OS and DFS.

Recent findings on the molecular basis of ovarian cancer development and progression create new opportunities to develop anticancer medications that would affect specific metabolic pathways and decrease side systemic toxicity of conventional treatment. Among new possibilities for cancer chemoprevention, much attention is paid to curcumin—A broad-spectrum anticancer polyphenolic derivative extracted from the rhizome of Curcuma longa L. According to ClinicalTrials.gov at present there are no running pilot studies, which could assess possible therapeutic benefits from curcumin supplementation to patients with primary epithelial ovarian cancer. Therefore, the goal of this review was to evaluate potential preclinical properties of curcumin and its new analogues on the basis of in vivo and in vitro ovarian cancer studies. Curcumin and its different formulations have been shown to display multifunctional mechanisms of anticancer activity, not only in platinum-resistant primary epithelial ovarian cancer, but also in multidrug resistant cancer cells/xenografts models. Curcumin administered together with platinum-taxane chemotherapeutics have been reported to demonstrate synergistic effects, sensitize resistant cells to drugs, and decrease their biologically effective doses. An accumulating body of evidence suggests that curcumin, due to its long-term safety and an excellent profile of side effects should be considered as a beneficial support in ovarian cancer treatment strategies, especially in patients with platinum-resistant primary epithelial recurrent ovarian cancer or multidrug resistant disease. Although the prospect of curcumin and its formulations as anticancer agents in ovarian cancer treatment strategy appears to be challenging, and at the same time promising, there is a further need to evaluate its effectiveness in clinical studies.

This study was conducted to evaluate the significance of circulating free DNA (CFDNA), p53 antibody (p53‐Ab) and mutations of KRAS gene in the development of endometrial cancer (EC). A total of 109 patients with EC (87 patients with Type I and 22 patients with Type II) took part in this study. KRAS mutations and CFDNA were detected by means of the PCR‐RFLP and enriched by the PCR‐RFPL method. ELISA was used to analyze plasma p53‐Ab. Tissue expression of P53 protein was evaluated immunohistochemically (IHC). The frequency of KRAS mutations was especially high in Grade 2 of Type I EC. CFDNA was frequently detected in patients with early stage of Type II EC at a low level of grade. It is noteworthy that the p53‐Ab positive rate increased in the higher grade of Type I tumors. A significant difference in the number of cases with the p53‐Ab was found in the advanced stage of Type I tumors. The frequency of KRAS and p53‐Ab correlates with tumor stage only in the Type I EC. Plasma CFDNA and p53‐Ab offer a chance to develop a procedure for EC Type II diagnosis. The association between tumor cells related to CFDNA and p53‐Ab with Type II tumor suggests that it might potentially serve as a marker in predicting the prognosis and offers a possibility to individualize treatment regimen.

Introduction and hypothesis The aim of this study was to evaluate the results of conservative treatment of urodynamic stress urinary incontinence (SUI) using transvaginal electrical stimulation with surface-electromyography-assisted biofeedback (TVES + sEMG) in women of premenopausal age. Methods One hundred and two patients with SUI were divided into two groups: active (n = 68) and placebo (n = 34) TVES + sEMG. The treatment lasted for 8 weeks and consisted of two sessions per day. Women were evaluated before and after the intervention by pad test, voiding diary, urodynamic test, and the Incontinence Quality of Life Questionnaire (I-QOL). Results Mean urinary leakage on a standard pad test at the end of 8th week was significantly lower in the active than the placebo group (19.5 ± 13.6 vs. 39.8 ± 28.5). Mean urinary leakage on a 24-h pad test was significantly reduced in the active group at the end of 8th and 16th weeks compared with the placebo group (8.2 ± 14.8 vs. 14.6 ± 18.9 and 6.1 ± 11.4 vs. 18.2 ± 20.8, respectively). There was also a significant improvement in muscle strength as measured by the Oxford scale in the active vs the placebo group after 8 and 16 weeks (4.2 vs 2.6 and 4.1 vs 2.7, respectively). No significant difference was found between groups in urodynamic data before and after treatment. At the end of 8th week, the mean I-QOL score in the active vs the placebo group was 78.2 ± 17.9 vs 55.9 ± 14.2, respectively, and at the end of 16th week 80.8 ± 24.1 vs. 50.6 ± 14.9, respectively. Conclusion Our study showed that TVES + sEMG is a trustworthy method of treatment in premenopausal women with SUI; however, its reliability needs to be established.

The aim of this study was to evaluate HE4, CA125 and ROMA in the preoperative differentiation benign ovarian diseases from epithelial ovarian cancer depending on the menopausal status. In order to estimate markers’ concentrations in the serum of women with benign ovarian disease (n = 128) and with epithelial ovarian carcinoma (n = 96) the electrochemiluminescence (ECLIA) technique has been applied. Using the ROC analysis, although no statistical differences were found among their AUCs, the ROMA algorithm seems to be effective in gathering the diverse performance of HE4 and CA125. The AUC for HE4, CA125 and ROMA for all patients were: 0.895; 0.879 and 0.918, respectively. At established new optimal cutoff values for HE4, CA125 and ROMA we found higher specificity in postmenopausal compared to premenopausal women (96.9 vs 89.8 % and 97.7 vs 84.1 % and 95.9 vs 89.1 %, respectively). The sensitivity of HE4 in pre- and postmenopausal women was similar (83.5 vs 83.8 %), while for CA125 was the highest in premenopausal women (87.0 vs 84.1 %). For HE4, CA125 and ROMA the negative predictive value was high (97.6, 93.9 and 94.4 %, respectively). The ROMA algorithm shows the best diagnostic performance to distinguish epithelial ovarian cancer from benign ovarian disease. We found the high specificity of HE4 and CA125 while differentiating ovarian benign diseases from epithelial ovarian cancer in postmenopausal women and the high sensitivity of CA125 in detecting epithelial ovarian cancer in premenopausal patients.

The significance of circulating levels of TNF-alpha and its soluble receptors (sTNF-Rs) in the plasma of patients with epithelial ovarian cancer (EOC) has not been fully elucidated. The present study was to investigate the relationship of pretreatment plasma levels of TNF-alpha, sTNFR-1 and sTNFR-2 with outcome in 126 patients with EOC. Concentrations of TNF-alpha and sTNF-Rs were determined by enzyme-linked immunosorbent assay (ELISA). Median TNF-alpha and sTNF-Rs levels were significantly higher in EOC patients than in healthy controls. High plasma levels of TNF-alpha and sTNF-Rs were correlated with tumor stage and with reduced mean survival time (MST). The results of the present study suggested that preoperative plasma TNF-alpha and sTNF-Rs levels in EOC patients correlated with the highest risk of cancer progression. Thus, the clinical value of an activated TNF system in EOC needs to be further investigated.
