RESUMO

Methotrexate (MTX) is a commonly used folic acid antagonist for the treatment of neoplasia and some autoimmune diseases. Resveratrol has important anti-inflammatory, antioxidant and immunomodulatory properties. The aim of this study was to investigate the effects of resveratrol on MTX-induced ovary-damage and oxidative stress in rats. We hypothesized that supplement of resveratrol could counteract MTX-induced cytotoxicity in rat ovary. Albino Wistar female rats were randomly divided into three groups: Healthy control (HC), resveratrol + methotrexate (RMTX) and methotrexate (MTX) group. Their ovaries were removed. Biochemical and histopathological methods were utilized for evaluation of the oxidative ovary-damage. MDA was found to be higher but tGSH and SOD were lower in the ovarian tissue of the rat group administered MTX, but it is observed that these ratios are reversed in HC and in RMTX groups. MTX treatment induced ovary damage and especially pre-treatment with resveratrol provided protective effect against this MTX-induced ovary-damaged.

RESUMO

The anti-cancer drugs, particularly those used in reproductive period, may cause several complications such as ovarian insufficiency and infertility. The mechanism of action of cisplatin toxicity on the ovaries is not fully described. However, further production of free oxygen radicals and reduced production of antioxidants are thought to have an effect on the occurrence of cisplatin toxicity. The aim of this study was to investigate the effects of lycopene on cisplatin-induced ovary-damage, oxidative stres and histological changes in rats. Albino Wistar female rats were randomly divided into three groups. The control group (Group 1) received sunflower oil; animals in Group 2 received only cisplatin; one hour of lycopene pre-treatment was applied to the animals in Group 3 before administration of cisplatin. Cisplatin (5 mg/kg/day) was intraperitoneally injected as a single dose and lycopene (0.5 mg/kg/day) was administered by gavage. Biochemical and histopathological methods were utilised for evaluation of the oxidative ovary-damage. There was an increase in the levels of malondialdehyde, while total glutathione, glutathione reductase, and superoxide dismutase were decreased in Group 3, but it is observed that these ratios are reversed in the Group 1 and in the Group 2. Lycopene had protective effect against cisplatin-induced ovary-damaged.

RESUMO

AIM OF THE STUDY: Fallopian tube cancer is very rare in the literature and so there are not enough data about the therapeutic approaches. The approaches are generally determined in accordance with the data obtained from ovarian cancer. Many prognostic factors have been investigated in an effort to better estimate patient outcome. Stage, age, and residual tumor after surgery are consistently important prognostic factors. In this study, we aimed to evaluate the prognostic factors and survival rates of primary fallopian tube cancer (PFTC), which is rare among gynecological cancers. MATERIAL AND METHODS: Thirty-eight patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of our Research and Training Hospital in the period 1995-2013. Clinicopathological and surgical data were collected. All patients were evaluated for survival and disease-free survival between the dates specified. RESULTS: A significant relationship and correlation was found between optimal surgery and life expectancy. Better results were obtained in patients treated with optimal surgery. The survival probability was found to be higher in patients with lower CA-125 levels and serous histologic type adenocarcinoma. CONCLUSIONS: Stage is one of the factors affecting the survival probability. We determined that the pathological type of tumor, the diameter of residual tumor remaining after surgery, tumor grade, preoperative CA-125 levels and presence of ascites affect the survival probability.

RESUMO

AIM OF THE STUDY: The present study aims to estimate the prevalence and distribution of HPV genotypes and identify related risk factors among Turkish women. MATERIAL AND METHODS: 11 624 Turkish women attending our gynaecological clinic and expressing a desire for access to cervical cancer screening were assessed during the years 2014-2016. Cervical specimens were collected and transported using the HC2 HPV DNA Collection Device (consisting of a cervical brush and digene Specimen Transport Medium). RESULTS: Among these 11 624 individuals, positive HPV test results were obtained for 325 (2.79%), and negative results were observed for 11 299 (97.2%). The vast majority of patients were between the 3rd and 5th decades and the mean age of the patients was 44 ±9.12 (range 27-66). Among the HPV-positive women, 205 were positive for a single HPV type (205/325 = 63.1% of HPV infections; 205/11624 = 1.76% of all samples) and 120 were positive for multiple types (120/325 = 36.9% of HPV infections; 120/11624 = 1.03% of all samples). The four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively. CONCLUSIONS: There appears to be geographic variation in the distribution of HPV genotypes. In this study, the four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively.
