Abstract
Ovarian cancer (OC) represents a serious health problem worldwide. In Mexico, most OC patients are detected at late stages, consequently making OC one of the leading causes of death in women after reaching puberty. Personalized medicine (PM) provides an individualized therapeutic opportunity for treating each patient relying on “omic” tools to match the correct drug with the specific pathogenic genomic signature. PM can help predict the best therapeutic option for each affected woman suffering from OC. In recent years, Mexico has made contributions to the PM of OC; however, it still has a long way to go for its full implementation in the country’s health system.

Abstract
Ovarian cancer is the seventh most common gynaecologic malignancy seen in women. Majority of the patients with ovarian cancer are diagnosed at the advanced stage making prognosis poor. The standard management of advanced ovarian cancer includes tumour debulking surgery followed by chemotherapy. Various types of chemotherapeutic regimens have been used to treat advanced ovarian cancer, but the most promising and the currently used standard first-line treatment is carboplatin and paclitaxel. Despite improved clinical response and survival to this combination of chemotherapy, numerous patients either undergo relapse or succumb to the disease as a result of chemotherapy resistance. To understand this phenomenon at a cellular level, various macromolecules such as DNA, messenger RNA and proteins have been developed as biomarkers for chemotherapy response. This review comprehensively summarizes the problem that pertains to chemotherapy resistance in advanced ovarian cancer and provides a good overview of the various biomarkers that have been developed in this field.

Zhang L, Zhou Q. Bevacizumab with dose-dense paclitaxel/carboplatin as first-line chemotherapy for advanced ovarian cancer. Eur J Pharmacol 2018; 837:64-71. [PMID: 30059681 DOI: 10.1016/j.ejphar.2018.07.049] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2018] [Revised: 07/25/2018] [Accepted: 07/26/2018] [Indexed: 11/17/2022]
Abstract
Phase III trials have shown improved survival in ovarian cancer patients when the anti-vascular endothelial growth factor (VEGF) therapy bevacizumab is added to first-line chemotherapy. However, further evidence is needed regarding bevacizumab when used with dose-dense paclitaxel/carboplatin chemotherapy in advanced ovarian cancer patients. This single-arm trial enrolled 184 advanced-stage (III-IV) epithelial ovarian cancer patients following primary debulking. Enrollees were treated with dose-dense paclitaxel/carboplatin chemotherapy with bevacizumab administered on the first day of cycles 2 through 6. Thereafter, maintenance bevacizumab was continued for 12 months in patients exhibiting persistent disease. The primary endpoint was the tumor response rate. The secondary endpoints were overall survival (OS), progression-free survival (PFS), and adverse effects. VEGF-associated serum markers and VEGFA/B lymphoma Mo-MLV insertion region 1 homolog (BMI1) pathway proteins in tumor-derived ovarian epithelial cancer cells were analyzed. Of the enrollees with residual disease that completed at least four cycles, 56.6% had a complete response and 3.7% had a partial response. OS and PFS were significantly different between optimally debulked and suboptimally debulked patients (P < 0.05). The most common grade 3/4 adverse event was neutropenia. Patients with progressive disease showed greater basal serum VEGFA and ovarian VEGFA/BMI1 pathway protein expression relative to patients with stable disease and responsive disease (P < 0.05). In conclusion, bevacizumab plus dose-dense paclitaxel/carboplatin shows efficacy and tolerability in advanced ovarian cancer patients, especially in those having received optimal resection. Our evidence also suggests a prognostic relationship between serum VEGFA levels and a worse prognosis in ovarian cancer patients with measurable disease.

Abstract
As an angiogenesis inhibitor, bevacizumab has been investigated in combination with different chemotherapeutic agents, achieving an established role for metastatic cancer treatment. However, potential synergic anti-angiogenic effects of hyperthermia have not tested to date in literature. The aim of our study was to analyze efficacy, safety, and survival of anti-angiogenic-based chemotherapy associated to regional deep capacitive hyperthermia (HT) in metastatic cancer patients. Twenty-three patients with metastatic colorectal (n = 16), ovarian (n = 5), and breast (n = 2) cancer were treated with HT in addition to a standard bevacizumab-based chemotherapy regimen. Treatment response assessment was performed, according to the modified Response Evaluation Criteria for Solid Tumors (mRECIST), at 80 days (timepoint-1) and at 160 days (timepoint-2) after therapy. Disease Response Rate (DRR), considered as the proportion of patients who had the best response rating (complete response (CR), partial response (PR), or stable disease (SD)), was assessed at timepoint-1 and timepoint-2. Chi-squared for linear trend test was performed to evaluated the association between response groups (R/NR) and the number of previous treatment (none, 1, 2, 3), number of chemotherapy cycles (<6, 6, 12, >12), number of hyperthermia sessions (<12, 12, 24, >24), and lines of chemotherapy (I, II). Survival curves were estimated by Kaplan-Meier method. DRR was 85.7% and 72.2% at timepoint-1 and timepoint-2, respectively. HT was well tolerated without additional adverse effects on chemotherapy-related toxicity. Chi-squared for linear trend test demonstrated that the percentage of responders grew in relation to the number of chemotherapy cycles (p = 0.015) and to number of HT sessions (p < 0.001) performed. Both overall survival (OS) and time to progression (TTP) were influenced by the number of chemotherapy cycles (p < 0.001) and HT sessions (p < 0.001) performed. Our preliminary data, that need to be confirmed in larger studies, suggest that the combined treatment of bevacizumab-based chemotherapy with HT has a favorable tumor response, is feasible and well tolerated, and offers a potentially promising option for metastatic cancer patients.

Abstract
Epithelial ovarian cancer (EOC) remains a clinical challenge and there is a need to optimise the currently available treatment and to urgently develop new therapeutic strategies. Recently, there has been improved understanding of the molecular characteristics and tumour microenvironment of ovarian cancers. This has facilitated the development of various targeted agents used concurrently with chemotherapy or as maintenance. Most of the studies have explored the tumour angiogenesis pathways. In phase-III trials, bevacizumab showed a statistically significant improvement in progression-free survival, although there was no improvement in overall survival in selected high-risk cases. Although several multi-targeted tyrosine kinase inhibitors were found to be useful, the toxicity and survival benefit has to be weighed. Poly ADP ribose polymerase (PARP) inhibitors have been another marvellous molecule found to be effective in breast cancer 1, early onset (BRCA)-positive ovarian cancers. Several newer molecules targeting Her 2, Wee tyrsine kinases, PIP3/AKT/mTR-signalling pathways, folate receptors are under development and may provide additional opportunities in the future. This article focuses on the targeted agents that have successfully paved the way in the management of epithelial ovarian cancer and the newer molecules that may offer therapeutic opportunities in the future.

Abstract
Ovarian cancer is the leading cause of death from gynecologic cancers in the United States. Failure may be due to variable expression and/or complex interactions of growth factor receptors in individual tumors. As ErbB3-MET cooperativity is implicated in solid tumor resistance to EGFR/ErbB2 inhibitors, we evaluated expression of MET and all 4 ErbB family members in ovarian cancers. Tissue arrays were prepared from archival formalin-fixed paraffin-embedded tumor samples, including 202 ovarian carcinomas (Stage I-IV) and controls. Of 202 patient samples, only 25% were positive for EGFR and 35% for ErbB2 expression. ErbB3, ErbB4, and MET showed marked expression in 76%, 98%, and 96% of cases. Consistent with high incidence, there was no significant correlation for expression of ErbB3, ErbB4, or MET with outcome. On the basis of their high expression in the majority of cases, inhibitors targeting ErbB3, ErbB4, and/or MET may be broadly applicable as therapeutic agents in this disease.

Abstract
OBJECTIVE To determine the safety and efficacy of the novel combination of docetaxel, oxaliplatin, and bevacizumab as first-line treatment of advanced cancer of the ovary, peritoneum or fallopian tube after initial debulking surgery. METHODS Eligible patients (stage IB-IV) were treated with 6 cycles of oxaliplatin (85 mg/m(2)), docetaxel (75 mg/m(2)), and bevacizumab (15 mg/kg) every 3 weeks, followed by single-agent bevacizumab 15 mg/kg every 3 weeks to complete one year of therapy. The primary endpoint was 12-month progression-free survival (PFS). RESULTS A total of 132 patients (80 with measurable disease at baseline; 52 with non-measurable, evaluable disease at baseline) enrolled and received study treatment. At diagnosis, 76.5% of patients had stage III disease and 20% had stage IV. 62.9% were optimally cytoreduced. The most common grade 3/4 adverse events were neutropenia (42.4%), leukopenia (13.6%), hypertension (8.3%), fatigue (6.1%), and nausea (6.1%). One patient (0.8%) had a fatal gastrointestinal perforation. The best overall confirmed response rate (complete response+partial response [measurable disease subgroup]) was 58.6% (95% CI 49%, 67%). CA-125 response rates for the measurable and non-measurable disease subgroups were 83.0% and 81.5%, respectively. The 12-month PFS rate for the measurable disease subgroup was 65.7% (95% CI 53.4%, 76.7%); median PFS was 16.3 (95% CI 12.6, 19.6) months. Median overall survival was 47.3 (95% CI 34.1, upper limit not applicable) months. CONCLUSIONS This novel treatment regimen may provide a promising therapeutic approach for women with ovarian, primary peritoneal, or fallopian tube carcinoma. No unanticipated safety concerns were identified.

Abstract
Background Platinum-based standard chemotherapy improves survival of ovarian cancer (OC), but the five-year survival rate remains below 50%. Antiangiogenic agents (7.5 or 15 mg/kg Bevacizumab, Bev) plus to standard chemotherapy improve progression-free survival (PFS) not overall survival (OS) in completed randomized controlled trials (RCTs). The efficacy and safety of two doses of Bev + standard chemotherapy remain controversial. Methods MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane databases and ClinicalTrials.gov were searched. The outcomes of eligible RCTs included PFS, OS and toxicities. Hazard ratio (HR) and relative risk (RR) were used for the meta-analysis and were expressed with 95% confidence intervals (CIs). Results Bev + chemotherapy improved PFS (HR, 0.82; 95% CI, 0.75 to 0.89; P = .000) and OS (HR, 0.87; 95% CI, 0.77 to 0.99; P = .026) in newly diagnosed OC (2 trials, 2776 patients), and PFS (HR, 0.48; 95% CI, 0.41 to 0.57; P = .000) in recurrent OC (2 trials, 845 patients). Bev + chemotherapy increased non-CNS bleeding (RR, 3.63; 95% CI, 1.81 to 7.29; P = .000), hypertension grade ≥ 2 (RR, 4.90; 95% CI, 3.83 to 6.25; P = .000), arterial thromboembolism (RR, 2.29; 95% CI, 1.33 to 3.94; P = .003), gastrointestinal perforation (RR, 2.90; 95% CI, 1.44 to 5.82; P = .003), and proteinuria grade ≥ 3 (RR, 6.63; 95% CI 3.17 to 13.88; P = .000). No difference was observed between the two Bev doses in PFS (HR, 1.04; 95% CI, 0.88 to 1.24) or OS (HR, 1.15, 95% CI, 0.88 to 1.50), but 15 mg/kg Bev increased toxicities. Conclusion Bev + standard chemotherapy delayed progression for newly diagnosed and recurrent OC, and improved survival for newly diagnosed OC. The 7.5 mg/kg dose appeared to be optimal for newly diagnosed OC patients with high risk for progression.

Abstract
Although epithelial ovarian cancer responds well to chemotherapy, patients presenting with advanced disease still have a poor prognosis. The clear role of angiogenesis in the development and progression of ovarian tumorigenesis has led to the development of several novel antiangiogenic agents; however, questions remain as how to best incorporate such agents into current treatment algorithms. Searches of PubMed (terms: angiogenesis, VEGF, tyrosine kinase inhibitor, bevacizumab and ovarian cancer) and of recent results from key oncology congresses (terms: drug names and ovarian cancer) were performed to identify relevant articles and abstracts. Clinical trials are ongoing to evaluate investigational antiangiogenic agents as a component of first-line chemotherapy, as a treatment option for recurrent disease, and as maintenance therapy for ovarian cancer. The antiangiogenic monoclonal antibody bevacizumab has demonstrated a progression-free survival benefit in combination with first-line paclitaxel/carboplatin and continued as maintenance therapy, and phase II data suggest therapeutic potential for several multitargeted tyrosine kinase inhibitors in ovarian cancer, with phase III results forthcoming for BIBF 1120, cediranib, and pazopanib. Antiangiogenic therapy remains a promising strategy for ovarian cancer, and it is hoped that results from ongoing trials will inform their optimal placement in the treatment paradigm.

Abstract
Ovarian cancer mortality ranks highest among all gynecologic cancers with growth factor pathways playing an integral role in tumorigenesis, metastatic dissemination, and therapeutic resistance. The HER and VEGF receptor (VEGFR) are both overexpressed and/or aberrantly activated in subsets of ovarian tumors. While agents targeting either the HER or VEGF pathways alone have been investigated, the impact of these agents have not led to overall survival benefit in ovarian cancer. We tested the hypothesis that cotargeting HER and VEGFR would maximize antitumor efficacy at tolerable doses. To this end, ovarian cancer xenografts grown intraperitoneally in athymic nude mice were tested in response to AC480 (pan-HER inhibitor, "HERi"), cediranib (pan-VEGFR inhibitor "VEGFRi"), or BMS-690514 (combined HER/VEGFR inhibitor "EVRi"). EVRi was superior to both HERi and VEGFRi in terms of tumor growth, final tumor weight, and progression-free survival. Correlative tumor studies employing phosphoproteomic antibody arrays revealed distinct agent-specific alterations, with EVRi inducing the greatest overall effect on growth factor signaling. These data suggest that simultaneous inhibition of HER and VEGFR may benefit select subsets of ovarian cancer tumors. To this end, we derived a novel HER/VEGF signature that correlated with poor overall survival in high-grade, late stage, serous ovarian cancer patient tumors.

INTRODUCTION Ovarian cancer is the most lethal gynecological cancer, mainly because of the advanced stage of the disease at diagnosis, with recent research investigating novel targets and agents into the clinical practice, with the aim to improve prognosis and quality of life. Angiogenesis is a significant target for ovarian cancer therapy. AREAS COVERED Areas covered in this review include the most common molecular pathways of angiogenesis, which have provided novel targets for tailored therapy in ovarian cancer patients. These therapeutic strategies comprise monoclonal antibodies and tyrosine kinase inhibitors. These drugs have as molecular targets such as vascular endothelial growth factor (VEGF), VEGF receptor, platelet-derived growth factor, fibroblast growth factor, angiopoietin and Ephrin type-A receptor 2. EXPERT OPINION The expansion in understanding the molecular biology that characterizes cancer cells has led to the rapid development of new agents to target important pathways, but the heterogeneity of ovarian cancer biology indicates that there is no predominant defect. This review attempts to discuss progress till date in tackling a more general target applicable to ovarian cancer angiogenesis.

Abstract
OBJECTIVES We sought to assess the response rate and toxicity of paclitaxel, carboplatin, andvorinostat primary induction therapy for the treatment of advanced-stage ovarian carcinoma. METHODS Patients were treated with 6 cycles of weekly paclitaxel (80 mg/m), carboplatin (6 times area under the curve), and vorinostat (200 mg) every 28 days according to an institutional review board-approved protocol. The subjects were eligible for response evaluation; in patients who achieved stable disease or better following the conclusion of primary induction chemotherapy, they were subsequently treated with a planned 12 cycles of paclitaxel (135 mg/m) and vorinostat (400 mg) maintenance chemotherapy every 28 days. RESULTS Eighteen patients received a combined 90 cycles (median, 6 cycles; range, 1-6 cycles) of primary induction chemotherapy. Of the 18 subjects, 7 demonstrated a complete response, and 2 subjects exhibited a partial response (a total response rate of 50.0%). Eight patients also received a combined total of 50 cycles (median, 5 cycles; range, 1-12 cycles) of consolidation therapy. Grade 3/4 neutropenia and thrombocytopenia were observed in 9 (56.3%) and 2 (12.5%) patients. One patient (6.3%) developed grade 3 anemia, and another (6.3%) manifested a grade 3 neuropathy. Remarkably, we observed a significant gastrointestinal event (eg, bowel anastomotic perforation) in 3 patients, which effectuated the study's closure. CONCLUSIONS Because the current study was prematurely terminated, we cannot derive a conclusive assessment regarding the efficacy of this treatment. Nevertheless, the high incidence of severe gastrointestinal toxicity warrants further consideration when using vorinostat in the adjuvant setting for patients who have undergone a bowel resection as part of their initial tumor debulking.

Abstract
Treatment of epithelial ovarian cancer involves surgical management with staging or debulking surgery and chemotherapy with a platinum and taxane-containing regimen. Despite achieving a 70-80 % complete remission, patients often will recur. Novel therapies are needed to improve the treatment of ovarian cancers. Tumor angiogenesis is a critical process involved in the growth and metastasis of ovarian cancer. Numerous phase II trials with angiogenesis inhibitors have been reported and have led to the development and completion of several recent phase III trials in both upfront and recurrent ovarian cancers. Future studies will need to focus on how and when to incorporate angiogenesis inhibitors in the treatment armamentarium for ovarian cancers.

Abstract
Ovarian cancer is the most lethal gynecological cancer, mainly because of the delay in diagnosis. Recently, much effort has been put into investigating and introducing novel targeted agents into clinical practice, with the aim of improving prognosis and quality of life. Angiogenesis is a possible target. The aim of this review is to investigate the most common molecular pathways of angiogenesis, which have provided novel targets for tailored therapy in patients with ovarian cancer. These therapeutic strategies include monoclonal antibodies and tyrosine-kinase inhibitors. These drugs have as molecular targets vascular endothelial growth factor, vascular endothelial growth factor receptors, platelet-derived growth factor, fibroblast growth factor, and angiopoietin. Bevacizumab was investigated in several Phase III studies, with interesting results. Today, there is strong evidence for introducing bevacizumab in the treatment of patients with advanced and recurrent ovarian cancer. Nevertheless, further investigations and large clinical trials are needed to understand the safety and effectiveness of bevacizumab, the optimal duration and timing of treatment, and activity in association with other chemotherapeutic and targeted agents. It also is necessary to identify biologic factors predictive of efficacy to choose the most appropriate antiangiogenic agent in the integrated treatment of epithelial ovarian cancer.

Bevacizumab in the treatment of ovarian cancer: a meta-analysis from four phase III randomized controlled trials. Arch Gynecol Obstet 2013; 288:655-66.

Abstract
BACKGROUND The aim of this meta-analysis was to summarize the efficacy and safety of bevacizumab in the treatment of ovarian cancer. METHODS We sought to identify randomised controlled trials (RCTs) by searching PubMed and Web of Science. Outcomes were objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events. RESULTS Four studies with 4,246 patients were included. Combination of bevacizumab and chemotherapy resulted in a statistically significant improvement in ORR (OR 2.165, 95 % CI 1.511-3.103) and in PFS (HR 0.691, 95 % CI 0.517-0.865), compared with chemotherapy alone. There was no evidence of a significant improvement in OS (HR 0.934, 95 % CI 0.826-1.041). It also had significantly increased risk of gastrointestinal events (OR 2.743, 95 % CI 1.580-4.763; P < 0.001), hypertension (OR 4.630, 95 % CI 3.737 to 5.737; P < 0.001), proteinuria (OR 4.872, 95 % CI 2.617-9.069; P < 0.001), and arterial thromboembolism (OR 1.994, 95 % CI 1.210-3.286; P = 0.007). CONCLUSION This meta-analysis suggests that the addition of bevacizumab to chemotherapy offers meaningful improvement in objective response rate and progression-free survival in ovarian cancer treatment, but does not benefit overall survival. It also significantly increased the occurrence of gastrointestinal events, hypertension, proteinuria, and arterial thromboembolism.

Abstract
Bevacizumab is a recombinant humanized monoclonal IgG1 antibody that targets vascular endothelial growth factor-A, and is indicated in the treatment of various tumors (colon, lung, renal, and glioblastoma). It has been recently approved for the treatment of ovarian cancer in various countries. This review summarizes the activity and toxicity of bevacizumab in the treatment of ovarian cancer, both as single-agent drug and in combination with cytotoxic chemotherapy. As a single-agent drug, it has shown response rates of 16-21% in the treatment of recurrent ovarian cancer. Two phase III randomized trials have been published evaluating the addition of bevacizumab to standard chemotherapy as front-line treatment of advanced ovarian cancer. In addition, trials evaluating the combination with chemotherapy in recurrent ovarian cancer (platinum-sensitive and platinum-resistant disease) have also been reported. All these trials showed a statistically significant improvement in progression-free survival although no improvement in overall survival has been reported. The main adverse event is hypertension. Other serious, but uncommon adverse events include gastrointestinal perforation as well as renal and central nervous system toxicity.

Abstract
INTRODUCTION Despite aggressive debulking surgery, intraperitoneal therapies and the use of new drugs for chemotherapy, patients with ovarian cancer (OC) still have poor prognosis and, therefore, new strategies for its management are needed. Molecular-targeted agents can be considered a new option in drug research. Several antigens related to OC have been isolated and they could be potential target of monoclonal antibodies (mAbs); therefore, different mAbs have been developed and are emerging as new potential OC treatments. AREAS COVERED This article aims to review the literature on the use of mAbs in the treatment of OC. The purposes of this manuscript are to offer a brief explanation of the mechanisms of action of mAbs and to help readers in understanding the current role of mAbs in the treatment of OC. EXPERT OPINION A deeper knowledge of the molecular biology of OC has brought new developments in targeted therapies. Among these therapies, bevacizumab demonstrated the higher clinical efficacy. Further larger trials are needed to better define the role of the other mAbs in OC treatment. There is a strong need to identify and validate robust biomarkers for a more focused patient selection and for tailoring therapies, optimizing dose and assessing response.

Abstract
Although significant success has been achieved in the treatment of advanced and recurrent ovarian cancer, there is clearly room for improvement. The use of targeted agents in this patient population has the promise to provide improved survival and quality of life. There are a myriad of relevant pathways under exploration in all settings of ovarian cancer. Clinical trial data are accumulating for antiangiogenic therapy, including vascular endothelial growth factor (VEGF)-specific inhibitors and multiple angiogenic signaling target inhibitors, as well as poly-ADP-ribose polymerase (PARP) inhibitors. Other types of tumorigenic pathway inhibitors, including those that target phosphatidylinositol-3-kinase (PI3K), mammalian target of rapamycin (mTOR), protein kinase B (AKT), Src, folate receptor alpha, and insulin-like growth factor-1 receptor (IGF-1R) pathways are in earlier phases of development for ovarian cancer. Attempts to target the epidermal growth factor receptor (EGFR) of ovarian tumors have been met with limited success; however, newer agents that inhibit this pathway show promise. Finally, with recognition of the role of Wee-1 in p53-deficient tumors, an inhibitor of this tyrosine kinase is being evaluated in recurrent ovarian cancer. The logistical challenge is to determine the optimal timing and proper combinations of novel agents independently as well as concomitantly with conventional chemotherapeutics. Reported results have been modest; however, our growing understanding of these pathways will be potentially reflected in greater impact on response and survival.

A study of docetaxel weekly or every three weeks in combination with carboplatin as first line chemotherapy in epithelial ovarian cancer: Hematological and non-hematological toxicity profiles. Oncol Lett 2013; 5:1140-1148.

Abstract
The purpose of this study was to compare the toxicity profiles of docetaxel administered on a weekly schedule and the standard three-week schedule in the treatment of advanced primary ovarian carcinoma. Eligible patients were treated with intravenous docetaxel (30 mg/m2) on days 1, 8 and 15, and carboplatin (AUC 5) on day 1 or with docetaxel (75 mg/m2) and carboplatin (AUC 5) on day 1; Q21 days for 6 cycles. This study was a pooled study of two primary phase II studies. A total of 108 patients received the weekly schedule and 59 patients received the three-week schedule. All patients were evaluated for toxicity. The overall response rate was 79% and the biochemical response 93% for the weekly schedule. The median overall survival rate was 35.3 months. Neutropenia was significantly more common (ANOVA; p<0.0001) in the three-week group than in the weekly group during all six courses of chemotherapy. Fever and infections were also more common in this group. Thrombocytopenia and anemia were slightly more common in the weekly group. Fatigue, epiphora, nail changes and taste disturbances were specific side-effects following weekly docetaxel. Peripheral sensory neuropathy (grade 1–2) increased with every cycle of treatment, but in a similar manner in the two groups. Grade 3–4 neuropathy was not recorded. Oral mucositis and myalgia were two side-effects associated with the three-week schedule. Nausea and vomiting, diarrhea and dyspnea were a limited problem in both groups. Cardiac toxicity was rare and did not differ between the two docetaxel schedules. The weekly administration was favored due to the lower rates of neutropenia, fever, infections, oral mucositis and myalgia. However, epiphora and nail changes were specific side-effects of the weekly treatment. Both regimens appeared to be rather well tolerated with similar compliance (66 and 70%) with regard to completion of the planned six courses of chemotherapy.

Abstract
Bevacizumab is the first antiangiogenic agent to have demonstrated benefit as first-line and maintenance therapy in epithelial ovarian cancer (EOC), with the Gynecologic Oncology Group 218 and ICON 7 phase III trials revealing significantly prolonged progression-free survival (PFS) for carboplatin/paclitaxel plus bevacizumab followed by bevacizumab maintenance versus carboplatin/paclitaxel alone. Results are forthcoming from several phase III maintenance trials of investigational antiangiogenic agents, each evaluating PFS as the primary endpoint: AGO-OVAR12/LUME-Ovar1 (nintedanib [BIBF 1120]), AGO-OVAR16 (pazopanib), and TRINOVA-1, -2, and -3 (AMG 386). Here we review available data and ongoing clinical trials of investigational antiangiogenic agents as maintenance therapy for EOC. Current controversies, including uncertainties regarding the (1) most appropriate clinical trial endpoints, (2) optimal dosing, duration, and timing of therapy (e.g., with first-line chemotherapy and/or as maintenance monotherapy), and (3) feasibility, tolerability, and cost of adding these agents to platinum/taxane regimens are also highlighted.

Abstract
OBJECTIVES The purpose of this study was to assess the response rate, toxicity, progression-free survival, and overall survival in a series of patients with advanced-stage ovarian carcinoma treated with a first-line weekly docetaxel and 3 weekly carboplatin regimen. METHODS All eligible patients were treated with intravenous docetaxel (30 mg/m) on days 1, 8, and 15, and carboplatin (area under the curve, 5) on day 1; every 21 days for at least 6 cycles. RESULTS One hundred six patients received at least one cycle of primary chemotherapy (median, 6.0; range, 1-9), and they were evaluable for toxicity assessment. Eighty-five patients had evaluable (measurable) disease and received at least 3 courses of chemotherapy and were evaluable for clinical response rate. The overall response rate was 78.8% (95% confidence interval, 70.1%-87.5%), and the biochemical response 92.8% (95% confidence interval, 87.2%-98.4%). The median progression-free survival was 12.0 months and the median overall survival was 35.3 months. Thirty-six patients (34.0%) experienced grades 3 and 4 neutropenia, which resulted in the removal of 3 patients. Six patients (5.7%) experienced grades 3 or 4 thrombocytopenia. No patients experienced grade 3 to grade 4 sensory neuropathy. Epiphora, nail changes, and fatigue were frequently recorded nonhematologic adverse effects. CONCLUSIONS The tolerable hematologic toxicity (no need for colony-stimulating factors) and the low rate of neurotoxicity (only grades 1-2) and response rates in line with the standard 3-week paclitaxel-carboplatin regimen for advanced primary ovarian carcinoma after suboptimal cytoreductive surgery make this regimen an interesting alternative in selected patients.

Abstract
INTRODUCTION In the past decade there have been many attempts to improve systemic treatment and thus the outcome of patients with ovarian cancer. However, neither the sequential addition of non cross-resistant drugs to standard chemotherapy comprising carboplatin and paclitaxel, nor triplet combination therapies with conventional chemotherapeutic drugs have improved outcomes. Instead, such approaches have led to an increase in the incidence of side effects. We are currently experiencing a shift toward the addition of molecularly targeted and biological anticancer therapies to standard treatment. Vascular endothelial growth factor (VEGF), which improves vitally important tumor vasculature, is secreted by a range of tumors, and a high level of VEGF is known to be an independent risk factor for aggressive disease in ovarian cancer. This finding led to the development in the 1990s of bevacizumab, a humanized monoclonal antibody against VEGF. DISCUSSION Several phase II trials and four phase III trials have demonstrated that bevacizumab is active in patients with advanced and recurrent ovarian cancer. Both phase III trials of bevacizumab as first-line therapy in advanced ovarian cancer (ICON 7/AGOOVAR 11 and GOG-0218) have shown that the addition of bevacizumab to chemotherapy and as maintenance therapy improves progressionfree survival (PFS). The phase III trials in platinum-sensitive (OCEANS) and platinumresistant, relapsed disease (AURELIA) have also demonstrated a benefit for bevazicumab with respect to PFS. The administration of bevacizumab to improve survival in patients with ovarian cancer is not without side effects and a broad discussion on the cost-effectiveness of this approach is ongoing. CONCLUSION This article presents clinical trial data on bevacizumab in the treatment of ovarian cancer and discusses the indication and pitfalls in the application of bevacizumab in patients with this malignancy.

Abstract
Significant toxicities from multiple cycles of chemotherapy often cause delays or early termination of treatment, leading to poor outcomes in ovarian cancer patients. Complementary modalities that potentiate the efficacy of traditional agents with fewer cycles and less toxicity are needed. Photodynamic therapy is a mechanistically-distinct modality that synergizes with chemo and biologic agents. A combination regimen with a clinically relevant chemotherapy cocktail (cisplatin + paclitaxel) and anti-EGFR targeted photoimmunotherapy (PIT) is evaluated in a murine model for ovarian carcinomatosis. Mice received either 1 or 2 chemotherapy cycles followed by PIT with a chlorine6-Erbitux photoimmunoconjugate and 25 J/cm2 light. PIT + 1 cycle of chemotherapy significantly reduced tumor burden, comparable to multiple chemotherapy cycles. Relative to 1 cycle of chemotherapy, the addition of PIT did not cause significant mouse weight loss, whereas 2 cycles of chemotherapy led to a significant reduction in weight. Irradiance-dependence on PIT efficacy was a function of the conjugation chemistry, providing an additional variable for optimization of PIT outcome.

Abstract
Ovarian cancer is the leading cause of death in women with gynecological cancer. Most patients are diagnosed at an advanced stage with a poor prognosis. Currently, surgical tumor debulking followed by chemotherapy based on platinum and taxane is the standard treatment for advanced disease. However, these patients remain at great risk for recurrence and developing drug resistance. Therefore, new treatment strategies are needed to improve outcomes for patients with advanced and recurrent ovarian cancer. Several agents targeted at particular molecules have been developed for ovarian cancer and are now entering clinical trials. The functional targets of these agents are aberrations in tumor tissues including angiogenesis, the human epidermal growth factor receptor family, poly(ADP-ribose) polymerase (PARP), mammalian target of rapamycin (mTOR) signaling pathway, and α-folate receptor (α-FR). The anti-angiogenic compound bevacizumab has been reported as the most effective targeted agent. Bevacizumab plus chemotherapy prolonged progression-free survival (PFS) both for advanced and platinum-sensitive recurrent ovarian cancer, but did not increase overall survival. A PARP inhibitor, olaparib, applied as maintenance treatment also improved PFS in platinum-sensitive relapsed ovarian cancer. Furthermore, mTOR inhibitors and a monoclonal antibody to α-FR, farletuzumab, are attractive treatment strategies either alone or combined with chemotherapy. Understanding the tumor molecular biology and identifying predictive biomarkers are essential steps in selecting the best treatment strategies. This article reviews available clinical data on the most promising targeted agents for ovarian cancer.

Abstract
Bevacizumab is a recombinant, humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody that neutralizes the biological activity of VEGF and inhibits tumour angiogenesis. In two pivotal, well designed, phase III, clinical trials (GOG-0218 and ICON7) in women with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer, first-line treatment with bevacizumab in combination with standard chemotherapy (carboplatin plus paclitaxel) followed by maintenance treatment with bevacizumab alone significantly prolonged progression-free survival relative to standard chemotherapy. A subgroup analysis of ICON7 suggested that bevacizumab therapy may also be beneficial in patients at high risk of disease progression. In GOG-0218, health-related quality of life (HR-QOL) deteriorated temporarily (during the chemotherapy phase) and slightly, although statistically significantly, with bevacizumab in combination with standard chemotherapy followed by bevacizumab maintenance relative to standard chemotherapy plus placebo maintenance. In ICON7, HR-QOL did not differ to a clinically significant extent between patients receiving bevacizumab plus standard chemotherapy followed by bevacizumab maintenance and those receiving standard chemotherapy alone. Bevacizumab combination therapy had generally acceptable tolerability in these studies, with the nature of adverse events generally similar to that observed in previous clinical trials in patients with other solid tumours.

Abstract
OBJECTIVE The purpose of this review was to provide an overview of angiogenesis, including the rationale for targeting angiogenesis as a treatment strategy for epithelial ovarian cancer (EOC) and to discuss available clinical trial data with antiangiogenic agents in EOC, with a focus on combinations with chemotherapy. METHODS This was a literature review of clinical studies evaluating select antiangiogenic agents in combination with traditional cytotoxic chemotherapy for the treatment of EOC. RESULTS Several therapies that target angiogenesis-specific pathways are undergoing clinical development for EOC. Although some of these agents have demonstrated single-agent activity for EOC, there is considerable interest in combining this treatment strategy with chemotherapy in an effort to potentially improve treatment benefits in this patient population. Bevacizumab, an anti-vascular endothelial growth factor (VEGF) monoclonal antibody, is the most studied antiangiogenic agent in EOC and has shown efficacy as monotherapy and combined with chemotherapy in both the relapsed/recurrent and first-line settings. However, results from recent phase 3 trials raise questions regarding patient selection and optimal dose, schedule, and duration of bevacizumab therapy. Other agents in various phases of testing include aflibercept (VEGF Trap), a fusion protein that binds all isoforms of VEGF; multitargeted antiangiogenic tyrosine kinase inhibitors (eg, BIBF 1120, cediranib, pazopanib, sorafenib); and AMG 386, a selective angiopoietin inhibitor. Toxicities associated with VEGF inhibition are also a concern with antiangiogenic therapy, including hypertension, proteinuria, thromboses, and gastrointestinal perforation. CONCLUSIONS Results from recently completed and ongoing clinical trials combining antiangiogenic agents with chemotherapy are awaited in hopes of expanding therapeutic options for patients with EOC.

Abstract
Gynecologic malignancies carry an estimated incidence of 83,750 cases per year and estimated mortality rate of more than 27,000 women per year. New therapies and therapeutic approaches are needed to improve the outlook for women with gynecologic cancers. Recent insights at the molecular and cellular levels are paving the way for a more directed approach to target mechanisms driving tumorigenesis. This article reviews the roles of new and emerging antiangiogenesis drugs, summarizes the data obtained from clinical trials of antiangiogenic agents, and discusses trials under way to address the role of such strategies in gynecologic cancers.

Abstract
Vascular endothelial growth factor (VEGF) is a key regulator of angiogenesis which drives endothelial cell survival, proliferation, and migration while increasing vascular permeability. Playing an important role in the physiology of normal ovaries, VEGF has also been implicated in the pathogenesis of ovarian cancer. Essentially by promoting tumor angiogenesis and enhancing vascular permeability, VEGF contributes to the development of peritoneal carcinomatosis associated with malignant ascites formation, the characteristic feature of advanced ovarian cancer at diagnosis. In both experimental and clinical studies, VEGF levels have been inversely correlated with survival. Moreover, VEGF inhibition has been shown to inhibit tumor growth and ascites production and to suppress tumor invasion and metastasis. These findings have laid the basis for the clinical evaluation of agents targeting VEGF signaling pathway in patients with ovarian cancer. In this review, we will focus on VEGF involvement in the pathophysiology of ovarian cancer and its contribution to the disease progression and dissemination.

Abstract
Despite efforts to improve chemotherapeutic efficacy in epithelial ovarian cancer, outcome for patients with advanced disease has remained unchanged since the introduction of standard carboplatin and paclitaxel. Interest has therefore shifted toward molecularly targeted therapies that interfere with important features of ovarian carcinogenesis, such as angiogenesis. Several angiogenesis inhibitors, targeting vascular endothelial growth factor (VEGF) ligands (bevacizumab, VEGF-Trap) or their receptors (VEGFR-targeted tyrosine kinase inhibitors) have been clinically evaluated. These agents demonstrated efficacy in phase II clinical trials. Results from phase III trials, in which bevacizumab was added to standard frontline chemotherapy, show a modest effect. Although the initial expectations for angiogenesis inhibitors have been tempered, further research is warranted to define their precise place in the treatment of ovarian cancer. This review summarizes the performed and ongoing studies with regard to angiogenesis inhibitors in ovarian cancer, and the available data on biomarkers for response prediction. Preclinical studies evaluating alternative angiogenesis inhibitors will also be discussed.

Abstract
Over the past two decades, empirical optimization of cytotoxic chemotherapy combinations and surgical debulking procedures have improved outcomes and survival in epithelial ovarian cancer. Yet, this disease remains the fifth leading cause of cancer-related deaths in the US, as cure rates seem to have reached a plateau at approximately 20% with conventional chemotherapy. Novel high-throughput genomic and proteomic analyses have improved the molecular understanding of ovarian carcinogenesis, thereby providing a vast array of new potential drug targets with complex signalling interactions. In order to yield the most significant impact on disease outcome, it is necessary to carefully select, and subsequently target, the driving molecular pathway(s) within a tumour or tumour subtype, which are most likely to correspond to high-frequency mutations and genomic aberrations. The identification of biomarkers predictive of response to targeted therapy is essential to avoid poor responses to potentially useful drugs in unselected trial populations. With some promising, albeit early, phase III data on the angiogenesis inhibitor bevacizumab, exciting new opportunities lie ahead with the ultimate goal of personalizing therapies to individual tumour profiles.

Abstract
Epithelial ovarian cancer is a leading cause of cancer-related death for women both in the United States and worldwide, and the effectiveness of cytotoxic chemotherapy has plateaued. Angiogenesis plays an important role in ovarian cancer biology, and exploration of anti-angiogenic agents in this disease has demonstrated anti-tumor activity both as monotherapy and in combination with cytotoxic chemotherapy. However, key questions remain regarding the use of these drugs in ovarian cancer, such as where in treatment should they be used, should these drugs be used as single agents or combined with chemotherapy, can and which biomarkers predict efficacy, are there efficacy and toxicity differences amongst the various agents, what are the cost-benefit ratios of these therapies, and are the patient outcome improvements observed in completed studies significant enough to warrant widespread use of these drugs? Here, we review recent progress and discuss ongoing controversies regarding the use of anti-angiogenic therapies in ovarian cancer.

Abstract
Ovarian cancer is the second most common gynaecological malignancy and the leading cause of death from gynaecological cancer. Although in some cases treatment is initially effective, there is a considerable risk of disease recurrence and resistance to therapy. Therapies targeting molecular alterations in tumours offer the promise of significantly improved treatment. So far, the most promising targeted agents are angiogenesis inhibitors and PARP inhibitors. Here, we review the various targeted therapeutic approaches under clinical investigation in phase I and II trials of ovarian cancer and the challenges facing their future success in the clinic.

Abstract
Despite recent advances in the management of ovarian cancer, it remains the most lethal gynecologic malignancy. Vascular endothelial growth factor (VEGF) has been shown to play a pivotal role in the progression of ovarian cancer leading to the eventual development of malignant ascites. On this basis, agents rendering VEGF ineffective by neutralizing VEGF (bevacizumab), blocking its receptors (aflibercept), or interfering with the postreceptor signaling pathways (sunitinib) provide us with the rational treatment options. These agents are generally used in combination with the standard chemotherapeutic drugs. Here, we discuss the basis of and the logic behind the use of these agents in the treatment of epithelial ovarian cancer, as well as their evaluation in different preclinical and clinical studies.

Abstract
Weight loss and muscle wasting are of critical importance to cancer patients because of their negative effects on survival, functional status, and tolerability of chemotherapy. Because previous data suggest vascular endothelial growth factor receptor inhibitors disrupt skeletal muscle pathways, such as PI3K and AKT, the current study explored weight loss and muscle wasting in colorectal cancer patients treated with bevacizumab. Patients were assessed for serial weight and radiographic changes in skeletal muscle at baseline and again within 3 months of starting cancer therapy. Computed tomography scans were used to assess muscle. Fifty-seven patients are the focus on this report. These patients manifested a decline in mean weight from 85 to 83 kilograms (P = 0.002). Mean skeletal muscle area at the L3 vertebral level dropped from 148 cm(2) to 145 cm(2) (P = 0.02). This drop in weight and skeletal muscle occurred independently of cancer progression. No statistically significant differences in survival were observed based on loss of weight or skeletal muscle. Colorectal cancer patients prescribed bevacizumab appear to lose weight and muscle over a few months even in the absence of cancer progression.

Abstract
Despite recent advances in the treatment of ovarian cancer, a large majority of women with this diagnosis will die from recurrence of their disease. Targeted therapies, in the form of monoclonal antibodies and small molecule tyrosine kinase inhibitors have significantly altered the management of many solid tumors and hematologic malignancies. No such agents have been approved by the US FDA for use in ovarian cancer, although Phase II data suggests excellent single-agent activity of some of these drugs. Antiangiogenic agents in combination with chemotherapy are being evaluated in Phase III clinical trials, both in the adjuvant setting and in recurrent platinum-sensitive disease. Poly-ADP-ribose polymerase inhibitors are promising agents in BRCA1/2-mutated breast and ovarian cancers. Ongoing clinical trials are exploring the anti-tumor effect of poly-ADP-ribose polymerase inhibitors administered as single agents and in combination with chemotherapy. Many other new drugs are in earlier grades of development. In this article, we review the state of the art in targeted therapies for ovarian cancer and identify future directions for their development in the management of this often devastating disease.

Abstract
Background Angiogenesis is a critical component of tumor development and proliferation, and increased angiogenesis has been associated with a worse clinical outcome in a number of solid tumors, including ovarian cancer. Therefore, agents that target the angiogenic process are of considerable interest in the treatment of ovarian cancer. Methods Studies evaluating the efficacy of antiangiogenic agents in ovarian cancer are reported. Antiangiogenic agents examined include vascular endothelial growth factor (VEGF) pathway inhibitors, including monoclonal antibodies, tyrosine kinase inhibitors (TKIs), and a soluble receptor decoy, as well as inhibitors of other angiogenic factors and vascular disrupting agents. Results The VEGF inhibitor bevacizumab has been shown to have efficacy in ovarian cancer in phase II trials and a progression-free survival advantage in one phase III trial. TKIs block the VEGF receptors and secondary angiogenic pathways and have shown activity in phase I and II trials. Alternative angiogenesis inhibitors include EphA2 inhibitors and a selective angiopoietin 1/2-neutralizing peptibody. Another strategy is to destroy the existing tumor vasculature, and a number of vascular disrupting agents are being studied in preclinical and phase I trials. Antiangiogenic agents have a unique side effect profile, likely due to inhibition of normal physiologic angiogenesis. Conclusions Phase II and early phase III trials have demonstrated that antiangiogenic therapies have significant activity in ovarian cancer. The results of phase III trials in the front-line and recurrent settings will determine the extent of clinical benefit of antiangiogenic therapies in combination with chemotherapy. Antiangiogenic agents have a distinct side effect profile, and further studies are necessary to evaluate how to minimize the incidence of these events and to identify women most likely to benefit from these therapies.

Abstract
OBJECTIVES Bevacizumab is a generally well-tolerated drug, but bevacizumab-associated gastrointestinal perforations (BAP) occur in 0 to 15% of patients with ovarian carcinoma. Our goal was to evaluate the clinical predictors of BAP in order to identify factors, which may preclude patients from receiving treatment. METHODS We conducted a review of patients with recurrent epithelial ovarian carcinoma treated with bevacizumab between 2006 and 2009. Demographic and treatment data were collected for statistical analysis. RESULTS Eighty-two patients were identified; perforation occurred in 8 (9.76%). Among patients with perforation, a significantly higher incidence of prior bowel surgeries (p=0.0008) and prior bowel obstruction or ileus (p<0.0001) were found compared to non-perforated patients. The median age at onset of bevacizumab in the perforated group was 3 years younger (60 vs. 63 years, p=0.61). The incidence of thromboembolic events, GI comorbidities, number of prior chemotherapies, and body mass index were similar between the groups. None of the patients in the perforated group developed grade 3 or 4 hypertension, compared to a 32.4% incidence among the non-perforated patients (p=0.09). Upon multivariate analysis, when controlled for age greater or less than 60, prior bowel surgery, obstruction/ileus, and grade 3 or 4 hypertension, only the presence of obstruction/ileus was noted to be a significant predictor of perforation (p=0.04). CONCLUSIONS Predicting BAP remains a challenge. Bowel obstruction or ileus appears to be associated with increased risk of BAP.

Abstract
Paclitaxel is a front-line agent for ovarian cancer chemotherapy, along with the platinum agents. Derived from the Pacific yew tree, Taxus brevifolia, paclitaxel has covered significant ground from the initial discovery of its antineoplastic properties to clinical applications in many forms of human cancers, including ovarian cancer. Although much has been published about the unique mechanism of action of this agent, several issues remain to be resolved. Finding the appropriate dosage schedule for paclitaxel in chemo-naïve and recurrent ovarian cancer, defining the role of paclitaxel in maintenance chemotherapy, and elucidating the mechanisms of taxane resistance are areas of intense research. Newer forms of taxanes are being manufactured to avoid troublesome adverse effects and to improve clinical efficacy. These issues are reviewed in detail in this paper with an emphasis on clinically relevant evidence-based information.

Abstract
PURPOSE OF REVIEW Epithelial ovarian cancer (EOC) is a prevalent gynecologic malignancy whose prognosis in most cases remains poor despite advances in therapy. In this article, we critically review the available clinical evidence for the choice of first-line chemotherapy in EOC and discuss promising therapeutic strategies. RECENT FINDINGS In the last 25 years, first-line chemotherapy regimens and the indication of systemic treatment for early-stage disease have been better established. Significant progress has been made in the treatment of advanced EOC with the optimization of the carboplatin plus paclitaxel regimen and the use of intraperitoneal chemotherapy for selected patients. Targeted therapies may be approved for EOC in the near future and this would bring more specific treatments and improve outcomes for patients. Validated biomolecular signatures to better define prognosis and to predict response to therapeutic agents are still lacking. SUMMARY The standard first-line chemotherapy in EOC is based on the doublet carboplatin plus paclitaxel. It may be possible to improve the efficacy of treatment by means of a more intensive dose-dense regimen or by the intraperitoneal delivery of chemotherapy. Significant improvements in the treatment of EOC are expected from the development of antiangiogenic and other targeted agents and from better patient selection.

Abstract
Ovarian cancer remains the leading cause of gynecological cancer-related mortality in the Western World despite the advances in surgical techniques and chemotherapy regimens over the past three decades. Although response rates and complete responses in advanced disease are >80% and 40-60%, respectively, after first-line treatment with carboplatin and paclitaxel, most of the patients will eventually relapse with a median progression-free survival of 18 months. Currently, research efforts have improved our understanding on the molecular biology of ovarian cancer and novel targeted treatment strategies are likely to contribute to the management of the disease and give the chance to an individualized therapeutic approach.
