Background: The purpose of this study was to investigate and evaluate risk factors for lymph node metastases (LNM) in cases of endometrial cancer (EC). Materials and Methods: A retrospective single institution analysis of patients surgically staged for EC at Ankara Oncology Education and Research Hospital from 1996 to 2010 was performed. Roles of prognostic factors, such as age, histological type, grade, depth of myometrial invasion, cervical involvement, peritoneal cytology, and tumor size, in the prediction of LNM were evaluated. Fisher's exact test and logistic regression analysis were used to assess the effects of various factors on LNM. Results: LNM was observed in 22 out of 247 patients (8.9%) and was significantly more common in the presence of tumors of higher grade, deep myometrial invasion (DMI), cervical involvement, size >2cm, and with positive peritoneal cytology. Logistic regression analysis revealed that DMI remained the only independent risk factor for LNM. NPV, PPV, sensitivity, and specificity for satisfying LNM risk were 98.0, 19.5, 86.3, and 65.3%, respectively for DMI. Conclusions: The incidence of LNM is influenced independently by DMI. If data support a conclusion of DMI, LND should be seriously considered.

To investigate the effects of Trichosanthes semen extract on the growth and apoptosis of human uterine cervical carcinoma cells. Effects of Trichosanthes semen extract on the growth of ME-180 cells were assayed by MTT assay. Apoptosis induced by Trichosanthes semen extract was detected by fluorescent microscopy, DNA fragmentation analysis and flow cytometry. Caspase-3 and caspase-8 activities were assayed. Trichosanthes semen extract induced ME-180 cells to die in a dose- and time-dependent manner. ME-180 cells treated with Trichosanthes semen extract exhibited typical characteristics of apoptosis. The population of Sub-G1 cells increased significantly, and the cells represented the reduced size, condensed chromatin and apoptotic bodies. They showed the decreased mitochondrial membrane potential and increased activities of caspase-3 and caspase-8. The results suggest that Trichosanthes semen extract induced ME-180 cell apoptosis and the activation of caspase and mitochondrial pathway were involved in the process of Trichosanthes semen extract-induced apoptosis.

Purpose : Polygonum cuspidatum extract is an oriental herb which has been used for uterine diseases. In this study, the effects of Polygonum cuspidatum extract were investigated on inducing growth inhibition and apoptosis of human uterine cervical carcinoma cells. Methods : Viability of Polygonum cuspidatum extract-induced ME-180 cells was measured by MTT assay. Apoptotic cells were visualized by EtBr/AcOr staining under fluorescent microscope. Nucleosomal DNA fragmentation was assayed by agarose gel electrophoresis. Cell cycle distribution and changes in mitochondrial membrane potential were observed by flow cytometry. Results : Polygonum cuspidatum extract induced ME-180 cell death in a dose- and time-dependent manner. In the cells treated with Pc, the population of cells at sub-G1 phase significantly increased, and the condensed nuclei, apoptotic bodies and nucleosome-sized DNA were detected. Moreover, reduction in mitochondrial membrane potential was detected. Conclusion : Polygonum cuspidatum extract inhibits the growth and proliferation of ME-180 cells by apoptotic induction and facilitates its activity initiated by depolarization of mitochondria.

The present study was carried out to investigate the possibility that bispidinone derivative makes anticancer drug availability to human cervical carcinoma cell. The B8 has the lowest IC50 value among B8, B9 and B10 which are bispidinone analogue with bromide. According to cytotoxic test through WST-8 assay, B8 shows the most magnificent cytotoxicity effectiveness with 76 μM of IC50 value. In human cervical carcinoma cell treated with B8, it noticeably controlled cellular multiplication by increase of concentration and time. Furthermore, morphological changes like cellular shrink, disruption and nuclear condensation, feature of apoptosis, are observed. Annexin V-FITC/PI double staining assay test proved that B8 can cause apoptosis. Moreover, after treatment with 76 μM of B8, flow cytometry analysis shows that increase of active oxygen species are induced and membrane potential in mitochondria is decreased. Manifestation of Bcl-2 family and caspase cascades protein provides evidence that B8 induces apoptosis through mitochondria and caspase-related pathway. Taken together, we suggested that B8 reduced membrane potential in mitochondria and induce apoptosis through the pathway depended on mitochondria and caspase.

Purpose : Despite a development of therapeutic machines and advance in modern radiation therapy techniques, locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate, Combination of chemotherapy and radiotherapy demonstrated benefit in improving local control and possibly the overall survival. Our study was performed to evaluate effect of concurrent chemoradiation on locally advanced uterine cervical cancer. Methods and Materials : Twenty six patients with locally advanced stage(FIGO stage IIB with ${\geq}5cm$ in diameter, III, IVA) were treated with combination of radiation therapy and concurrent cisplatinum between May of 1988 and September of 1993 at our hospital. Radiation therapy consisted of external irradiaton and 1-2 sessions of intracavitary irradiation. Cisplatinum was administered in bolus injection of 25mg/$m^2$ at weekly intervals during the course of external radiation therapy. Results : Of the 26 Patients, twenty-five patients were evaluable for estimation of response. Median follow-up period was 25 months with ranges from 3 to 73 months. Stage IIB, III, and IVA were 16, 5, 4 patients, respectively, Twenty patients were squamous cell carcinoma. Response was noted in all 25 patients: complete response(CR) in 17/25($68\%$), Partial response(PR) in 8/25($32\%$). Of the 24 patients except one who died of sepsis at 3 months follow-up, seventeen patients($70.8\%$) maintained local control in the pelvis: 16/17($94.1\%$) in CR, 1/17($14.3\%$) in PR. Fourteen of the 17 patients with CR are alive disease free on the completion of follow-up. Median survival is 28 months for CR and 15 months for PR. Analysis of 5-year survival by stage shows 11/16($59.8\%$) in IIB, 3/5($60.0\%$) in III, and 1/4($25.0\%$) in IVA. Overall 5-year survival rate was $55.2\%$. Ten patients recurred: 4 at locoregional, 3 in distant metastasis and 3 with locoregional and distant site. Toxicity by addition of cisplatinum was not excessive. Conclusion : Although the result of this study was obtained from small number of patients, it is rather encouraging in view of markedly improved response rate compared with the results of historical group.

Aims: To study alterations of plasma lipid profiles in carcinoma cervix and to assess significance comparedwith controls in different histological grades and stages. Materials and Methods: Totals of 99 histopathologically diagnosed cases and 35 controls from a tertiary hospital situated in the southern part of India which caters the rural and semi-urban populations were considered for the study. Fasting blood samples were taken to analyze total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoproteins cholesterol (LDL-C), for comparison of cases, grouped according to histological grades and stages, and controls. One way ANOVA was used for multiple group comparisons and the Student's t test (unpaired) for group wise comparisons. For all tests a 'p' value of 0.05 or less was considered as significant. Results: Out of 99 cases, most (n-39) were seen in the 40-49 year age group followed by 60-69 years (n-22). Serum TG significantly differed between cases and controls but without any relation to differentiation grade. The lipid profile parameters in various grades of cervical cancer were not statistically significant. Statistically significant increase of TC and LDL-C values was observed with increase in stage of the disease. Conclusions: The study showed TG is elevated in cervical cancer, and that TC and LDL-C are proportional to the spread of cancer as it increases from stage I to stage IV. An in-depth study of molecular changes in lipid metabolism in cervical cancer patients, enzymes/genes responsible and alterations in LDL receptors is necessary to provide information to decide whether the lipid profile has any diagnostic/prognostic role in cervical cancer.

Purpose: Although the role of squamous cell carcinoma antigen (SCC-Ag) as a predictive and prognostic factor for uterine cervical cancer has been identified in previous studies, 1) the effective patient group of screening for recurrence with SCC-Ag, 2) the relationship between SCC-Ag and recurrence site, and 3) the relationship between the change of SCC-Ag and treatment outcome or recurrence have not been described. Materials and Methods: The study included 506 patients with histologically proven uterine cervical cancer between January 1994 and December 2010. We determining the serum SCC-Ag level before treatment and after treatment, and conducted a retrospective review of the patients' records. We evaluated the sensitivity and specificity of SCC-Ag for the detection of tumor recurrence by comparing biochemical recurrence with clinical recurrence. Results: The pretreatment SCC-Ag level and the proportion of patients over 1.5 ng/mL were higher in poor prognostic patient group. In the univariate and multivariate analysis, pretreatment SCC-Ag showed a statistically significant correlation with tumor size, International Federation of Gynecology and Obstetrics (FIGO) stage, pathology. In patients with biochemical recurrence vs. those without, 5-year DFS and OS were 27.6 vs. 92.7% (p ${\leq}$ 0.001) and 53.7 vs. 92.5% (p ${\leq}$ 0.001), respectively. Conclusion: Our study reconfirmed the known function of pretreatment SCC-Ag, but could not confirm the function of biochemical response as a predictive factor for treatment and as a prognostic factor. There was no statistically significant relationship between SCC-Ag level and recurrence site. We confirmed the role of SCC-Ag as a follow-up tool for recurrence of disease and which patient groups SCC-Ag was more useful for.

Human papillomavirus is a virus that is distributed worldwide, and persistent infection with high-risk genotypes (HR-HPV) is considered the most important factor for the development of squamous cell cervical carcinoma (SCC). However, by itself, it is not sufficient, and other factors may contribute to the onset and progression of lesions. For example, infection with other sexually transmitted diseases such as human immunodeficiency virus (HIV) may be a factor. Previous studies have shown the relationship between HPV infection and SCC development among HIV-infected women in many regions of the world, with great emphasis on low- and middle-income countries (LMICs). Brazil is considered a LMIC and has great disparities across different regions. The purpose of this review was to highlight the current knowledge about HPV infection and cervical abnormalities in HIV+ women in Brazil because this country is an ideal setting to evaluate HIV impact on SCC development and serves as model of LMICs and low-resource settings.
