Abstract
Ovarian cancer (OC) remains a fatal malignancy because most patients experience recurrent disease, which is resistant to chemotherapy. The outcomes for patients with platinum-resistant OC are poor, response rates to further chemotherapy are low and median survival is lower than 12 months. The complexity of platinum-resistant OC, which comprises a heterogeneous spectrum of diseases, is indeed far from being completely understood. Therefore, comprehending tumors' biological behaviour to identify reliable biomarkers, which may predict responses to therapies, is a demanding challenge to improve OC management. In the age of precision medicine, efforts to overcome platinum resistance in OC represent a dynamic and vast field in which innovative drugs and clinical trials rapidly develop. This review will present the exceptional biochemical environment implicated in OC and highlights mechanisms of chemoresistance. Furthermore, innovative molecules and new therapeutic opportunities are presented, along with currently available therapies and ongoing clinical trials.

Abstract
It has previously been reported that astrocyte‑elevated gene‑1 (AEG‑1) has a critical role in the regulation of tumor development, and/or progression. However, the functional significance of AEG‑1 in human ovarian cancer remains unclear. The present study conducted an immunohistochemical analysis of ovarian tissues, and the association between AEG‑1 protein expression, clinicopathological features and outcomes were investigated. The gain or loss of AEG‑1 function was also examined, through exogenous overexpression or knockdown of expression by small interfering RNA, in ovarian cancer cells. Normal ovarian tissue exhibited very little or no AEG‑1 immunoreactivity, whereas high expression levels of AEG‑1 were detected in 12.7% of cystadenomas, 30.0% of borderline tumors, and 71.2% of ovarian carcinomas, respectively, as determined by immunohistochemistry. Statistical analyses demonstrated a significant correlation of AEG‑1 expression with differentiation (P=0.001), lymph node metastasis (P=0.008) and clinical staging (P=0.002). In addition, the overall survival time of patients with higher AEG‑1 expression levels was markedly shorter, as compared with patients with lower expression levels of AEG‑1 (P=0.001). Multivariate analysis indicated that AEG‑1 expression was an independent prognostic indicator of the survival of patients with ovarian cancer. Furthermore, exogenous overexpression of AEG‑1 in ovarian cancer cells was shown to significantly enhance cell proliferation, adhesion and invasion. Conversely, silencing AEG‑1 expression caused an inhibition of cell growth, adhesion and invasion. The results of the present study indicate that AEG‑1 is a valuable biomarker for the prediction of ovarian cancer prognosis, and AEG‑1 inhibition may be a potential therapeutic strategy for ovarian cancer treatment.

Abstract
Objectives:Most patients with ovarian cancer are candidates for second-line or salvage treatments often for prolonged periods. Patients with platinum-sensitive disease can benefit from a platinum retreatment with a likelihood of response dependents on the treatment-free interval. Alternative agents and combination chemotherapy are potential therapeutic approaches. At our institution, we carried out a phase II trial to evaluate feasibility, efficacy, and toxicity of gemcitabine and vinorelbine combination in recurrent ovarian carcinoma. The aim of the present study was to evaluate the role of this combination in patients with platinum-sensitive disease.Patients and Methods:Patients with platinum-sensitive disease recurring after 1 or more lines of platinum-based chemotherapy were included. Vinorelbine at 25 mg/m2followed by gemcitabine at 1000 mg/m2was administered intravenously on days 1 and 8 every 3 weeks. Response Evaluation Criteria in Solid Tumors and cancer antigen 125 test (CA-125 Kinetics [Rustin criteria]) were adopted to classify responses. Toxicity was assessed according to the National Cancer Institute Common Toxicity Criteria.Results:Thirty-nine patients were eligible. Platinum-free interval (PFI) was 6 to 12 months in 13 patients (33.3%; PFI 6-12) and more than 12 months in 26 patients (66.7%; PFI > 12). The overall response rate was 48.7%, with 6 complete responses. Median response duration was 38 weeks. The response rate was 23% in PFI 6-12 and 62% in PFI >12. The most frequently observed toxicity was hematological, with 23% of the patients having grade 3 or 4 neutropenia.Conclusions:Gemcitabine and vinorelbine combination is effective and well tolerated in recurrent platinum-sensitive ovarian cancer. It may represent an option in the management of these patients because the chronic nature of the disease.

Abstract
PURPOSE To determine the dose-limiting toxicities (DLTs) and the maximum tolerated doses (MTDs) of the paclitaxel, gemcitabine, oxaliplatin combination administered biweekly in patients with advanced solid tumors. PATIENTS AND METHODS Patients received escalated doses of paclitaxel (starting dose: 100 mg/m(2)), gemcitabine (starting dose: 800 mg/m(2)) and oxaliplatin (starting dose: 50 mg/m(2)) on days 1 and 15 in cycles of every 4 weeks. DLTs were evaluated during the first cycle. RESULTS Twenty-seven patients (median age 65 years) with performance status 0-1 were treated on six dose escalation levels. Eleven patients (40.7%) were chemotherapy naïve, six (22.2%) had received 1 prior chemotherapy regimen and ten (37.1%) 2 or more. The DLT level was reached at the doses of paclitaxel 110 mg/m(2), gemcitabine 1,150 mg/m(2) and LOHP 70 mg/m(2). The dose-limiting events were grade 4 neutropenia and grade 3 febrile neutropenia. Neutropenia was the most common adverse event. A median of 3 cycles per patient was administered. One complete and five partial responses were observed in patients with ovarian carcinoma, NSCLC, urothelial cancer, mesothelioma and cancer of unknown primary. No pharmacokinetic drug interactions were detected. CONCLUSIONS The recommended doses for future phase II studies of this combination are paclitaxel 110 mg/m(2), gemcitabine 1,000 mg/m(2) and oxaliplatin 70 mg/m(2) every 2 weeks. The regimen is generally well tolerated and merits further evaluation.

Abstract
TheInternational Symposium on Advanced Ovarian Cancer: Optimal Therapywas founded by Dr. Andrés Poveda and Prof. Jan B. Vermorken, and each edition has been directed by them. The 6th edition was held on March 2, 2007. This symposium is organized every other year by GEICO (Grupo Español de Investigación de Cáncer de Ovario/Spanish Ovarian Cancer Research Group), under the auspices of the Spanish Society of Medical Oncology (SEOM), the Gynecologic Cancer Intergroup (GCIG), and the European Society of Medical Oncology (ESMO) Educational Committee for its Medical Oncology Recertification Approval (ESMO/MORA) Program. One hundred and fifty people attended the symposium's 1st edition, held in 1996. Since then, the interest in this meeting has increased. Last year, almost three hundred people coming not only from Spain but also from Europe, North and Latin America, Asia, and Australia were present in the symposium. This is a great challenge for us. Some important international cooperative groups from Europe, America, and Australia collaborate with this symposium, such as GOG, NCIC, EORTC, AGO, Scottish Group, ICON, GINECO, NSGO, ANZGOG, and others.

Abstract
OBJECTIVE This metaanalysis was undertaken to evaluate the relationship between tea intake and ovarian cancer risk. STUDY DESIGN A systematic literature search up to September 2006 was performed in Medline, Embase, CANCERLIT, and the Cochrane Database. The summary relative risk was calculated. A sensitivity analysis was conducted to test the influence of each single study. Heterogeneity and publication bias were also evaluated. RESULTS Two cohort and 7 case-control studies were included. The combined relative risk did not show that tea consumption was associated with a reduced ovarian cancer risk (relative risk, 0.84; 95% confidence interval, 0.66-1.07). When the analyses were stratified into subgroups, there was no evidence that study design substantially influenced the estimate of effects. The sensitivity analysis which means removing one study at a time confirmed the stability of our results. CONCLUSION Our findings did not support that tea consumption was related to the decreased risk of ovarian cancer.

Abstract
Ovarian and cervical cancers are significant health problems. This article provides an update in selected management topics. Paclitaxel and platinum derivatives are the first-line treatment for patients with advanced disease. In selected patients, intraperitoneal chemotherapy has been associated with improved survival but the broad applicability of this strategy is limited by issues of toxicity and feasibility. Management of patients with recurrent disease is based on a number of factors and includes surgery in selected cases, platinum-based chemotherapy for patients with platinum-sensitive disease and other agents such as topotecan and pegylated liposomal formulation of doxorubicin for patients with platinum-resistant disease. In cervical cancer, the most significant issue/event is the demonstration of superior survival with topotecan and cisplatin compared to cisplatin alone. Finally, new agents such as epidermal growth factor receptor inhibitors and antiangiogenic agents are being currently tested in these settings.

Abstract
National and international specialists have met with the aim of writing down the guidelines for the treatment of epithelial ovarian cancer (in the Spanish Castilian language). These guidelines are based on the International Consensus that was published in English in the Annals of Oncology in 2005. This condition is the leading cause of death from gynaecological cancer in western countries. Its low rate of survival, barely 30% at 5 years, is above all due to late diagnosis and inappropriate surgery, so emphasis is put on these aspects. After describing the methodology for early detection and a scheme of surgical diagnostic procedures in view of the staging of an ovarian mass, the following therapeutic strategies will be recommended: cytoreductive surgery together with platinum chemotherapy under normal conditions, and also in the case of relapse. Likewise, very recent models of treatment focused on molecular targets are presented, and a broad section on methodology of clinical assays. As for this, co-operation among groups is crucial in order to make the conclusions of these studies valid for the development of new therapies.

Abstract
Gemcitabine and oxaliplatin have shown single-agent activity in relapsed ovarian cancer. This combination was used to determine response rates, time-to-event efficacy measures, and toxicity in patients with recurrent ovarian cancer. Patients with prior platinum-based chemotherapy who had measurable lesions and/or elevated CA-125 levels were identified as group A (platinum-refractory/platinum-resistant patients) and group B (platinum-sensitive patients). All patients received gemcitabine 1000 mg/m(2) on days 1 and 8 and oxaliplatin 130 mg/m(2) on day 8 every 21 days for up to eight cycles. Seventy-five patients (21 in group A and 54 in group B), with a median age of 58 years (range, 37-78), were enrolled. A median of six cycles (range, 1-8) was administered. By intent-to-treat analysis, 15 patients with measurable disease achieved partial response for an overall best response rate of 20.0% (9.5% in group A and 24.1% in group B). CA-125 response was observed in 48.4% patients (30.0% in group A and 57.1% in group B). Median time to progressive disease was 7.1 months (95% CI, 5.6-9.0 months) with 5.0 months in group A and 8.3 months in group B. Median overall survival was 17.8 months (95% CI, 12.9-21.3 months) with 9.2 months for group A and 20.0 months for group B. Major grade 3/4 toxicities were neutropenia (61.3%), leukopenia (24.0%), nausea (16.0%), and vomiting (22.7%). We conclude that the combination of oxaliplatin and gemcitabine is active in patients with recurrent ovarian cancer, but the regimen is unsatisfactory for further study due to modest response and relatively high toxicity.

Abstract
The aim of this exploratory phase II study was to evaluate sequential chemotherapy with carboplatin followed by gemcitabine-paclitaxel combination in chemonaive patients with advanced ovarian cancer. The primary objective was to evaluate time to progressive disease (TTPD); secondary objectives included the evaluation of 1- and 3-year survival, response rates, and toxicity. Following initial debulking surgery or biopsy, patients with FIGO stage IIC-IV disease received four cycles of carboplatin area under the curve (AUC) 6 (day 1) every 21 days, followed by four cycles of gemcitabine 1000 mg/m(2) (days 1 and 8) and paclitaxel 175 mg/m(2) (day 8) every 21 days. A total of 47 patients enrolled, 44 (93.6%) completed the initial four cycles, and 39 patients (82.9%) completed the planned eight cycles. The median and maximum lengths of follow-up were 31.2 and 43.7 months, respectively. Median TTPD was 13.8 months (95% CI, 11.6-21.0 months), and median survival time was 31.2 months (95% CI, 25.2-39.6 months). Survival at 1 and 3 years was 95.7% and 44.2%, respectively. Of the 43 evaluable patients, most (95.3%) of them achieved a CA-125 marker response based on Gynecologic Cancer Intergroup (GCIG) definition. The partial response rate in the seven patients with measurable disease was 46.4%. Myelosuppression was the major toxicity, with grade 3 and 4 neutropenia observed in 76.6% patients and thrombocytopenia in 12.8% patients. The sequential approach of carboplatin followed by gemcitabine-paclitaxel as first-line treatment for patients with ovarian cancer is feasible and well tolerated, and depending upon the findings from other major trials, it may merit further evaluation.

Abstract
The present study was undertaken with the question about the outcome (recurrence-free survival, [RFS]) after adjuvant chemotherapy with taxane and carboplatin in the early stages of epithelial ovarian cancer after primary surgery. Treatment-related toxicity was also evaluated. A total of 113 patients were included in this study. The 5-year RFS rate for all 113 patients treated with adjuvant chemotherapy including taxane and carboplatin after primary surgery was 79%. The 5-year RFS rate for 85 patients in FIGO stage I was 85% and for 18 patients in FIGO stage II, it was 44%. For clear-cell carcinomas, the RFS was 87%. In univariate analysis, recurrent disease was associated with both FIGO stage and tumor grade, but in multivariate logistic regression analysis of prognostic factors for tumor recurrences, only FIGO stage (stage I versus stage II) was a significant and independent prognostic factor. However, an odds ratio (OR) of 1.9 for tumor grade (grade 3 versus grades 1-2) demonstrated two times increased risk for recurrence in a patient with a grade 3 tumor compared with grade 1-2 tumors. Furthermore, an OR of 0.39 for lymph node sampling versus no sampling meant 61% reduced risk for recurrence for a patient who had undergone lymph node sampling at surgical staging laparotomy. The major toxicities in the present study were myelosuppression (46%) and neurotoxicity (34%). Despite the use of prophylaxis, severe paclitaxel-related hypersensitivity occurred in three patients (3%).

Abstract
Ovarian cancer (OC) still represents the most lethal of gynecological malignancies with the chance for death in 5 years exceeding the chance for life. In recent years, the development of knowledge in molecular biology of OC coupled with the new technologies offers enormous opportunity to learn about aetiology of OC, and also give us a powerful tool for early diagnosis, prognosis and treatment of this disease. In particular, small cancer specimens from patients have become extremely informative thanks to techniques such as laser capture microdissection (LCM), tissue lysate arrays (TLAs), reverse trascriptase polymerase chain reaction (RT-PCR), and mass spectrometry. All of this coupled with advancements in bioinformatics have allowed the explosion of genomics, transcriptomics and proteomics. This paper focusses on the influence that advancement in the "-omics" bio-technology will reserve in OC diagnosis, prognostic characterization, and treatment.
