Abstract
INTRODUCTION The cost-effectiveness of adding bevacizumab biosimilar with or without chemotherapy (CT) and drug wastage in treating platinum-resistant recurrent ovarian cancer (PRrOC) was assessed. METHODS A three-state partitioned-survival model to compare the clinical and economic outcomes in the treatment of patients with PRrOC from a Taiwan healthcare prospective, extrapolated to two years based on data obtained from the JGOG3023 clinical trial. The primary outcomes of the model were incremental cost-effectiveness ratios (ICERs). RESULTS In the base-case scenario, using vials of bevacizumab biosimilar (Bevbiol) plus chemotherapy, the ICER was (new Taiwan dollar) NT$ 4,555,878 per QALY gained. The incremental cost savings of an incremental 2.02 QALYs were NT$ 1,605,828 if weight-based Bevbiol plus chemotherapy were used, but the ICER remained high at the willingness-to-pay (WTP) threshold. If the cost of Bevbiol were reduced to 50% per vial, adding it to CT would be cost-effective at an acceptable WTP threshold of NTD 2,994,200, with an ICER of NT$ 2,975,484. CONCLUSIONS Bevacizumab biosimilars in mg/kg dosage form with chemotherapy are still not cost-effective in Taiwan, but using weight-based dosing will reduce drug waste and save treatment costs.

Insights into ovarian cancer: chemo-diversity, dose depended toxicities and survival responses. Med Oncol 2023; 40:111. [PMID: 36871128 DOI: 10.1007/s12032-023-01976-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 02/09/2023] [Indexed: 03/06/2023]
Abstract
Ovarian cancer has been one of the serious concerns for female health and medicinal practitioner all over the world. The wellness of over cancer patient is associated with survival responses which depends on many factors including chemotherapeutic diversity; treatment protocol; dose-dependent toxicity such as hematological toxicity and non-hematological toxicity. We found that the studied treatment regimens (TRs) (1-9) showed varying degree of hematological toxicities like moderate neutropenia (< 20%) critical neutropenia (> 20%), negligible leucopenia, critical leucopenia (> 20%), moderate thrombocytopenia (< 20%), critical thrombocytopenia (> 20%), moderate anemia (< 20%) and critical anemia (> 20%). The studied TRs showed varying degree of non-hematological toxicities like moderate nausea-vomiting (< 20%), critical nausea-vomiting (> 20%), moderate alopecia (< 20%), critical alopecia (> 20%), moderate fatigue (< 20%), critical fatigue (> 20%), moderate neurotoxicity (< 20%), critical neurotoxicity (> 20%), moderate diarrheas (< 20%). The studied TRs showed varying degree of survival responses like critical partial response (> 35%), remarkable overall responses (> 60%), critical overall responses (< 60%), remarkable stable disease (> 20%), critical stable disease (< 20%) and moderate progressive disease (< 20%). Out of the studied TRs 1-9, in case of TR 6, moderate non-hematological toxicity (NHT) and effective survival response (SR) is being diluted by critical hematological toxicity (HT). On the other hand, TR 8, 9 is showing critical HT, NHT and SR. Our analysis revealed that the toxicity of the existing therapeutic agents can be controlled through judicious decision of drug administration cycles and combination therapies.

Abstract
Ovarian cancer is one of the most lethal gynecological malignancies worldwide, and chemoresistance is a critical obstacle in the clinical management of the disease. Recent studies have suggested that exploiting cancer cell metabolism by applying AMP-activated protein kinase (AMPK)-activating agents and distinctive adjuvant targeted therapies can be a plausible alternative approach in cancer treatment. Therefore, the perspectives about the combination of AMPK activators together with VEGF/PD-1 blockade as a dual-targeted therapy against ovarian cancer were discussed herein. Additionally, ferroptosis, a non-apoptotic regulated cell death triggered by the availability of redox-active iron, have been proposed to be governed by multiple layers of metabolic signalings and can be synergized with immunotherapies. To this end, ferroptosis initiating therapies (FITs) and metabolic rewiring and immunotherapeutic approaches may have substantial clinical potential in combating ovarian cancer development and progression. It is hoped that the viewpoints deliberated in this review would accelerate the translation of remedial concepts into clinical trials and improve the effectiveness of ovarian cancer treatment.

The efficacy and safety profile of 2-weekly dosing of bevacizumab-containing chemotherapy for platinum-resistant recurrent ovarian cancer. Int J Clin Oncol 2021; 26:2123-2129. [PMID: 34308512 PMCID: PMC8520859 DOI: 10.1007/s10147-021-01996-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Accepted: 07/19/2021] [Indexed: 12/03/2022]
Abstract
Background Despite being widely used, to date (June 2021), the regimen of bevacizumab 10 mg/kg every 2 weeks (Q2W) combined with chemotherapy is not approved in Japan for patients with platinum-resistant recurrent ovarian cancer. In this retrospective analysis, we evaluated the usage patterns of bevacizumab administered for platinum-resistant recurrent ovarian cancer. Methods We obtained clinical data from 155 Japanese medical facilities between November 2013 and December 2018 via a survey. Items included the number of cases of platinum-resistant recurrent ovarian cancer treated with bevacizumab according to dosage. For regimens including bevacizumab 10 mg/kg Q2W, additional information was requested relating to concomitantly administered agents, and the efficacy and safety of the regimen. Results Of 1739 bevacizumab-containing regimens reported in 1633 patients with recurrent ovarian cancer, 264 used 10 mg/kg Q2W. The overall response rate (ORR) with this regimen was 26.1%. Response rates varied according to regimen and were particularly favorable when bevacizumab 10 mg/kg Q2W was administered with paclitaxel (ORR, 53.0%) versus liposomal doxorubicin (15.0%; P < 0.0001) and irinotecan (7.7%; P < 0.028). The most frequent Grade ≥ 3 adverse events associated with bevacizumab 10 mg/kg Q2W were neutropenia (11.7%) and hypertension (11.7%). The most frequent bevacizumab-associated Grade ≥ 3 adverse events with bevacizumab plus paclitaxel versus bevacizumab plus liposomal doxorubicin were hypertension (9.0% versus 13.9%) and proteinuria (3.0% versus 8.4%). Conclusions Bevacizumab 10 mg/kg Q2W appears efficacious for patients with recurrent ovarian cancer, with a manageable toxicity profile. Approval of this regimen is clinically desirable for Japanese patients with ovarian cancer.

Abstract
Objective Anlotinib, an oral small-molecular tyrosine kinase inhibitor (TKI) on tumor angiogenesis and growth, has a wide spectrum of inhibitory effects on targets such as vascular endothelial growth factor receptors 2/3 (VEGFR2/3), etc. The efficacy and safety of anlotinib in the treatment of platinum-resistant or platinum-refractory ovarian cancer were evaluated. Patients and Methods Patients with platinum-resistant or platinum-refractory ovarian cancer that treated with anlotinib in the Affiliated Cancer Hospital of Zhengzhou University from May 2018 to March 2020 were included. Medical records were reviewed in terms of objective response, survival outcomes, and safety. Results A total of 38 patients were analyzed. The median progression-free survival and the median overall survival were 7.7 months (95% CI: 6.7–8.7) and 16.5 months (95% CI: 13.3–19.7), respectively. About 17 patients received anlotinib monotherapy, and the median progression-free survival was 7.7 months (95% CI: 6.3–9.1). A total of 19 cases received anlotinib plus chemotherapy with a median progression-free survival of 8.0 months (95% CI: 4.8–11.2). A total of 2 cases received anlotinib plus anti-PD-1 antibody pembrolizumab, and 1 case had partial response, the other progressive disease. The objective response rate was 42.1% while the disease control rate was 86.8%. A total of 5 patients experienced dose reduction from 12 mg to 10 mg because of adverse effects. The most common adverse effects were hypertension (31.6%), fatigue (28.9%), anorexia (26.3%) and hand-foot syndrome (23.7%). No treatment-related deaths were recorded. Conclusion Anlotinib produced moderate improvements in progression-free survival and overall survival in patients with platinum-resistant or platinum-refractory ovarian cancer. It indicates that anlotinib maybe a new treatment option for patients with platinum-resistant or platinum-refractory ovarian cancer.

Abstract
OBJECTIVES The optimal systemic therapy strategy for advanced epithelial ovarian cancer (EOC) remains unclear. We performed a systematic review and meta-analysis to assess oncologic outcomes and toxicity of bevacizumab combination treatment in advanced EOC. METHODS We conducted an electronic search of all phase 2 and 3 clinical trials involving bevacizumab combination therapy in advanced-stage EOC between 2010 and March 2020, using Embase, Medline, Epub Ahead of Print, Cochrane for clinical trials, Cochrane Database of Systematic Reviews, Web of Science and clinicaltrials.gov databases. Progression-free survival (PFS), overall survival (OS), and their hazard ratios (HR) when available were extracted. Pooled HR were calculated for each efficacy endpoint in the meta-analysis using inverse variance weighted method. Bias was assessed using the Cochrane Collaboration Risk of Bias I (ROB1) tool for randomized controlled trials. RESULTS Thirty-five studies were included in the qualitative analysis and eight studies in the quantitative synthesis. In the first-line setting, bevacizumab combined with chemotherapy revealed a significant improvement in PFS (pooled HR = 0.72, 95% CI 0.65-0.81) when compared to chemotherapy alone but no significant OS benefit (pooled HR = 0.88, 95% CI 0.72-1.06). In the recurrent setting, bevacizumab combinations showed significant PFS (pooled HR = 0.52, 95% CI 0.47-0.58) and OS benefits (pooled HR = 0.88, 95% CI 0.79-0.99) compared with non-bevacizumab regimens. Rate of bowel perforation was low at 1.24% (range 0-4.2%). CONCLUSIONS Bevacizumab-containing regimens are associated with significant PFS benefit in advanced and recurrent epithelial ovarian cancer. While the difference in OS did not reach statistical significance in the first-line setting, bevacizumab was associated with improved survival in the recurrent setting.

Abstract
In patients undergoing debulking surgery for ovarian cancer (OC), bevacizumab-combined chemotherapy has been reported to be associated with an increased incidence of adverse events (AEs). Reports in the literature have noted the overall morbidity of bevacizumab to be between 3.7% and 9%. The aim of this study is to report uncommon and unusual manifestations of morbidity in surgical cases performed at our third level referral centers for gynecologic oncology. Additionally, we review the rare and severe bevacizumab-related complications that have been described in the literature. We defined as "extreme", the particularly rare and/or severe complications up to determining a life-threatening condition or death, which are related to the use of bevacizumab. A case-series of extreme complications registered at our institutions were reported. In addition, a literature search of the PubMed, MEDLINE and EMBASE electronic databases was performed for this review. The studies collected included: 8 randomized controlled trials (RCT) and 5 prospective observational, 1 prospective phase-IV, 10 prospective phase-II, 2 prospective phase-I, and 20 retrospective studies, as well as 9 case reports. Bevacizumab was administered as primary treatment in adjuvant and neo-adjuvant setting in 16 and 5 studies respectively, as treatment for recurrence in 36 trials, and for secondary cytoreductive surgery (SCS) in 3 studies. The overall population administered with bevacizumab numbered 7,096 women. Extreme complications were observed in 591 patients, with a morbidity rate of the 8.3%. Overall, central nervous system (CNS), cardiovascular, gastrointestinal (GI) and primary infectious complications were seen in 22 patients (0.3%), 261 patients (3.7%), 159 patients (2.2%), and 8 patients (0.13%), respectively. Hemorrhagic and wound complications occurred in 18 women (0.25%), and 112 women (1.6%), respectively. Extreme complications related to the use of bevacizumab are rare, and often go unrecognized. The recognition and immediate management of such rare and life-threatening complications in patients treated at third level referral centers could significantly improve patient survival.

Abstract
Ovarian cancer growth under hypoxic conditions results in hypoxia-inducible factor-1α (HIF1α) stabilization. HIF1α is an adverse prognostic factor that may contribute to worse outcomes via its capacity to bind to p53, potentially blocking p53-mediated apoptosis. We determined whether HIF1α-p53 binding occurred in hypoxic ovarian cancer cell lines, and if this blocked p53 transcriptional activity. Topotecan (TPT), used in the treatment of ovarian cancer, inhibits HIF1α translation via a topoisomerase-1 (TOPO1)-dependent mechanism. We examined if TPT knockdown of HIF1α restored p53 transcriptional function. TPT effects on HIF1α and p53-related transcriptional targets were assessed by PCR. Associations between TPT effects and TOPO1 expression levels were examined by Western blots and knockdown by siRNA. RNA-binding protein immunoprecipitation was used to assess if TOPO1 was resident on HIF1α mRNA. We determined if sublethal doses of TPT, used to knockdown HIF1α, reversed hypoxia-related cisplatin and paclitaxel resistance (XTT assay). Flow cytometry was used to assess HIF1α-mediated upregulation of ABCB1 and ABCB5 efflux pump expression. We found that HIF1α binding to, and inhibition of, p53 transcriptional activity in hypoxic ovarian cancer cells was associated with drug resistance. TPT-mediated downregulation of HIF1α in hypoxic cells required TOPO1 resident on HIF1α mRNA, restored p53 transcriptional activity, downregulated ABCB1/ABCB5 cell surface expression, and reversed hypoxia-related cisplatin and paclitaxel resistance. IMPLICATIONS: TPT-mediated reduction of HIF1α accumulation in hypoxic ovarian cancer cell lines restores p53 tumor-suppressor function, offering a novel approach to reverse chemoresistance. Further clinical investigation is warranted.

Abstract
OBJECTIVE Stereotactic body radiation therapy (SBRT) has been successfully used to treat oligometastases of several primary tumors, but few experiences have been described in patients with gynecological oligometastatic cancer, particularly in ovarian neoplasm. The aim of this study was to evaluate the role of this new radiotherapy modality in a series of oligometastatic ovarian cancer patients. MATERIALS AND METHODS Clinical records of patients affected by oligometastatic ovarian carcinoma treated with SBRT were reviewed. RESULTS Twenty-six patients with 44 metastatic lesions (lymph nodes, 63.6%; liver, 31.8%; and lung, 4.5%) treated with SBRT between January 2011 and May 2017 were analyzed. After a median follow-up period of 28.5 months (range, 6-86 months), 17 patients (65.4%) were still alive at time of analysis: 6 are without evidence of disease, 11 experienced a disease progression. Eight patients died of disease, 1 died because of an heart attack while being disease free. The median local control (LC) was not reached. One-, 2-, and 5-year LCs were 92.9%. Median progression-free survival was 19 months, with 1-year progression-free survival of 69.3% and 38% at 2 years, 19% at 5 years. Median overall survival was 64.5 months, with all patients alive after 1 year, 92.7% at 2 years, and 61.7% at 5 years. Five (11.3%) cases experienced G2 toxicity; most common adverse effect was nausea and vomiting (3 cases [6.8%]) followed by abdominal pain (2 cases [4.5%]). None of the patients had grade 3 or grade 4 acute or late toxicity. CONCLUSIONS In conclusion, SBRT is a feasible and safe approach for selected cases of oligometastatic ovarian cancer, with satisfactory results in terms of LC and disease free survival.

Abstract
Metronomic chemotherapy, continuous and dose-dense administration of chemotherapeutic drugs with lowered doses, is being evaluated for substituting, augmenting, or appending conventional maximum tolerated dose regimens, with preclinical and clinical studies for the past few decades. To date, the principle mechanisms of its action include impeding tumoral angiogenesis and modulation of hosts' immune system, affecting directly tumor cells, their progenitors, and neighboring stromal cells. Its better toxicity profile, lower cost, and easier use are main advantages over conventional therapies. The evidence of metronomic chemotherapy for personalized medicine is growing, starting with unfit elderly patients and also for palliative treatment. The literature reviewed in this article mainly demonstrates that metronomic chemotherapy is advantageous for selected patients and for certain types of malignancies, which make it a promising therapeutic approach for filling in the gaps. More clinical studies are needed to establish a solidified role for metronomic chemotherapy with other treatment models in modern cancer management.

Trends in treatment during the last stages of life in end-stage gynecologic cancer patients who received active palliative chemotherapy: a comparative analysis of 10-year data in a single institution. BMC Palliat Care 2018; 17:99. [PMID: 30086748 PMCID: PMC6081917 DOI: 10.1186/s12904-018-0348-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Accepted: 07/09/2018] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Palliative chemotherapy should be used with caution when attempting to alleviate symptoms in patients with end-stage cancer. However, palliative chemotherapy continues to be utilized in cancer patients during their last stages of life. In this study, we analyzed the pattern of chemotherapy administered during the last 6 months of life in patients with end-stage gynecologic cancer who were treated with active palliative chemotherapy for the past 10 years. METHOD We retrospectively analyzed the data for patients with gynecologic cancer who died after undergoing active palliative chemotherapy without receiving hospice management at Asan Medical Center from 2006 to 2015. Patients were divided into two groups: those who died between 2006 and 2010, and those who died between 2011 and 2015. Based on the electronic medical records, the demographic and baseline characteristics of the patients, hospital admission during the last 6 months, invasive procedures, palliative chemotherapy patterns, and the time of the last chemotherapy session were confirmed. RESULTS A total of 193 patients with gynecologic cancer were eligible for this study. 92 patients died during 2006 to 2010, and 101 patients died during 2011 to 2015. The mean frequency of admission during the last 6 months was 5.12 for those who died in 2006-2010 and 6.06 for those who died during 2011-2015 (p = 0.003); similarly, the mean frequency of palliative chemotherapy during the last 6 months was 3.84 (2006-2010) vs. 4.93 times (2011-2015; p < 0.001). The proportion of patients undergoing invasive procedures during the last 3 months was 41.3% (2005-2010) vs. 56.4% (2011-2015; p = 0.044). CONCLUSIONS The frequency of palliative chemotherapy and the rate of invasive procedures have increased in patients with end-stage gynecologic cancer who were treated aggressively without hospice management over 2011-2015 when compared to 2006-2010, along with an increase in the mean frequency of admission during the last 6 months at our institution. Gynecologic oncologists need to evaluate whether active palliative chemotherapy is beneficial to patients at the end-of-life stage, and if not helpful, should communicate with the patients and caregivers about when the palliative chemotherapy should be discontinued.

Adding bevacizumab to single agent chemotherapy for the treatment of platinum-resistant recurrent ovarian cancer: A cost effectiveness analysis of the AURELIA trial. Gynecol Oncol 2017; 145:340-345. [PMID: 28291545 DOI: 10.1016/j.ygyno.2017.02.039] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2016] [Revised: 02/21/2017] [Accepted: 02/24/2017] [Indexed: 11/23/2022]
Abstract
OBJECTIVE AURELIA, a randomized phase III trial of adding bevacizumab (B) to single agent chemotherapy (CT) for the treatment of platinum-resistant recurrent ovarian cancer, demonstrated improved progression free survival (PFS) in the B+CT arm compared to CT alone. We aimed to evaluate the cost effectiveness of adding B to CT in the treatment of platinum-resistant recurrent ovarian cancer. METHODS A decision tree model was constructed to evaluate the cost effectiveness of adding bevacizumab (B) to single agent chemotherapy (CT) based on the arms of the AURELIA trial. Costs, quality-adjusted life years (QALYs), and progression free survival (PFS) were modeled over fifteen months. Model inputs were extracted from published literature and public sources. Incremental cost effectiveness ratios (ICERs) per QALY gained and ICERs per progression free life year saved (PF-LYS) were calculated. One-way sensitivity analyses were performed to evaluate the robustness of results. RESULTS The ICER associated with B+CT is $410,455 per QALY gained and $217,080 per PF-LYS. At a willingness to pay (WTP) threshold of $50,000/QALY, adding B to single agent CT is not cost effective for this patient population. Even at a WTP threshold of $100,000/QALY, B+CT is not cost effective. These findings are robust to sensitivity analyses. CONCLUSIONS Despite gains in QALY and PFS, the addition of B to single agent CT for treatment of platinum-resistant recurrent ovarian cancer is not cost effective. Benefits, risks, and costs associated with treatment should be taken into consideration when prescribing chemotherapy for this patient population.

Abstract
OBJECTIVES To evaluate the efficacy and safety of irinotecan and bevacizumab in recurrent ovarian cancer. The primary objective was to estimate the progression free survival (PFS) rate at 6months. Secondary objectives included estimation of overall survival (OS), objective response rate (ORR), duration of response, and an evaluation of toxicity. METHODS Recurrent ovarian cancer patients with no limit on prior treatments were eligible. Irinotecan 250mg/m2 (amended to 175mg/m2 after toxicity assessment in first 6 patients) and bevacizumab 15mg/kg were administered every 3weeks until progression or toxicity. Response was assessed by RECIST or CA-125 criteria every 2cycles. RESULTS Twenty nine patients enrolled (10 were platinum-sensitive and 19 were platinum-resistant). The median number of prior regimens was 5 (range 1-12); 13 patients had prior bevacizumab and 11 prior topotecan. The PFS rate at 6months was 55.2% (95% CI: 40%-77%). The median number of study cycles given was 7 (range 1-34). Median PFS was 6.8months (95% CI: 5.1-12.1months); median OS was 15.4months (95% CI: 11.9-20.4months). In this study, no complete response (CR) was observed. The objective response rate (ORR; PR or CR) for all patients entered was 27.6% (95% CI: 12.7%-47.2%) and the clinical benefit rate (CR+PR+SD) was 72.4% (95% CI: 52.8%-87.3%); twelve patients experienced duration of response longer than 6months. In the 24 patients with measurable disease, a partial response (PR) was documented in 8 (30%) patients; 13 patients maintained stable disease (SD) at first assessment. The most common grade 3/4 toxicity was diarrhea. No treatment-related deaths were observed. CONCLUSIONS Irinotecan and bevacizumab has activity in heavily pre-treated patients with recurrent ovarian cancer, including those with prior bevacizumab and topoisomerase inhibitor use.

Abstract
Two topotecan treatment schedules in patients with recurrent epithelial ovarian cancer were evaluated. Protocol A (21 days) was 1.5 mg/m(2)/day topotecan on days 1 through 5 of a 21-day cycle; Protocol B (weekly) 4 mg/m(2) on days 1, 8, and 15 of a 28-day cycle. Efficacy was determined by clinical exam, CT scan, and CA125 levels. Forty-three patients on Protocol A and 21 on Protocol B were evaluated. As second-line treatment, Protocol A response was 9/20 (45%). Response to Protocol B was 4/17 (23.5%; NS). As third line or more, the response on Protocols A and B together was only 3/27 (11%). High-grade haematological toxicity was reported in 12/43 (27.9%) on Protocol A and 1/21 (4.8%) on Protocol B (p = 0.04). There was no difference in progression-free-intervals between schedules in second-line treatment. The weekly protocol had lower severe haematological toxicity. Clinical response in third line or more was very low.

Abstract
Patients with platinum-resistant ovarian cancer have progression of disease within 6 months of completing platinum-based chemotherapy. While several chemotherapeutic options exist for the treatment of platinum-resistant ovarian cancer, the overall response to any of these therapies is ~10%, with a median progression-free survival of 3–4 months and a median overall survival of 9–12 months. Bevacizumab (Avastin), a humanized, monoclonal antivascular endothelial growth factor antibody, has demonstrated antitumor activity in the platinum-resistant setting and was recently approved by US Food and Drug Administration for combination therapy with weekly paclitaxel, pegylated liposomal doxorubicin, or topotecan. This review summarizes key clinical trials investigating bevacizumab for recurrent, platinum-resistant ovarian cancer and provides an overview of efficacy, safety, and quality of life data relevant in this setting. While bevacizumab is currently the most studied and clinically available antiangiogenic therapy, we summarize recent studies highlighting novel alternatives, including vascular endothelial growth factor-trap, tyrosine kinase inhibitors, and angiopoietin inhibitor trebananib, and discuss their application for the treatment of platinum-resistant ovarian cancer.

Abstract
Objective To evaluate the treatment and survival pattern of patients with advanced epithelial ovarian cancer. Methods and results Retrospective study of all advanced epithelial ovarian cancer patients treated in the department of gynaecologic oncology from an academic centre, in a four year period from 1 January 2008–31 December 2011. Selection criteria All patients with advanced epithelial ovarian cancer (stage III and IV) who underwent surgery from 2008–2011and had a follow-up of at least three months after completion of treatment were included. The decision on whether primary surgery or neoadjuvant chemotherapy (NACT) in advanced ovarian cancer was based on age, performance status, clinical and imaging findings. Results A total of 178 cases of epithelial ovarian cancer were operated on during this four year period. Among them 28 patients were recurrent cases, 22 had early stages of ovarian cancer, and the rest 128 had stage III and IV ovarian cancer. In these 128 patients, 50(39.1%) underwent primary surgery and 78(60.9%) had NACT followed by surgery. In the primary surgery group 36(72.0%) patients had optimal debulking while in the NACT group 59(75.6%) patient had optimal debulking. With a median follow-up of 34 months, the median overall survival (OS) and progression free survival (PFS) was 53 and 49 months respectively. Patients who underwent primary surgery had better median PFS than patients who had NACT (56 months versus 39 months, p = 0.002). In stage III C the difference median PFS was significant for those treated with primary surgery when compared with NACT (55 months versus 39 months, p = 0.012). In patients who had optimal debulking to no residual disease (n = 90), primary surgery gave a significant improved PFS (59 months versus 38 months, p = 0.001) when compared with NACT. In univariate analysis, NACT was associated with increased risk of death (HR: 0.350; CI: 0.177–0.693). Conclusion In advanced epithelial ovarian cancer, primary surgery seems to have a definite survival advantage over NACT in patients who can be optimally debulked to no residual disease.

Abstract
The poor outcome of patients with recurrent ovarian cancer constitutes a continuous challenge for decision-making in clinical practice. In this setting, molecular targets have recently been identified, and novel compounds are now available. Bevacizumab has been introduced for the treatment of patients with ovarian cancer and is, to date, the most extensively investigated targeted therapy in this setting. However, potential toxicities are associated with the use of this monoclonal antibody. These toxicities have been reported in clinical trials, and can also be observed outside of trials. As limited data is currently available regarding the safety of bevacizumab treatment in daily clinical practice, the current retrospective study was designed to evaluate this. Data from 156 patients with recurrent ovarian cancer who had received bevacizumab treatment between January 2006 and June 2009 were retrospectively identified from the institutional records of five French centers. In contrast to clinical trials, the patients in the present study were not selected and had a heterogeneous profile according to their prior medical history, lines of treatment prior to bevacizumab introduction and number of relapses. The results first confirm the effect of heavy pretreatment on the occurrence of serious and fatal adverse events in clinical practice, as previously reported for clinical trials and for other retrospective cohort studies. Importantly, the data also demonstrates, for the first time, that medical history of hypertension is an independent predictive risk factor for the development of high-grade hypertension during bevacizumab treatment. These results thus suggest that treating physicians must consider all risk factors for managing bevacizumab toxicity prior to its introduction. Such risk factors include the time of bevacizumab introduction, a patient's history of hypertension and a low incidence of pre-existing obstructive disease.

Abstract
INTRODUCTION Patients with epithelial ovarian cancer (EOC) have a high rate of recurrence, and overall survival remains at ∼ 25%. There is a need for new treatments that can increase progression free survival and quality of life. Recent clinical trials focus on angiogenesis, VEGFs, and tyrosine kinase inhibitors that play a role in recurrence, metastasis, and ascites in EOC. AREAS COVERED This review summarizes clinical rationale, mechanisms of action, and clinical data for angiogenesis inhibitors under evaluation in Phase II and III trials for EOC. Anti-angiogenesis agents reviewed in this paper include aflibercept, bevacizumab, cediranib, fosbretabulin, imatinib, nintedanib, pazopanib, saracatinib, sorafenib, sunitinib, and trebananib. EXPERT OPINION These agents have particular rationale for potential use in EOC due to the molecular changes associated with EOC tumorigenesis, namely a significant increase in angiogenic activity. Due to the costs and toxicities associated with anti-angiogenics, biomarker or molecular signature selection strategy for patients who will most benefit would be ideal but no such strategy has been validated to date.

OBJECTIVE We attempted to investigate the safety and efficacy of alternative weekly topotecan dosing in a heavily pretreated Taiwanese population with recurrent epithelial ovarian cancer (EOC) and primary peritoneal carcinoma (PPC). MATERIALS AND METHODS We retrospectively reviewed the medical records of patients with recurrent EOC and PPC who had been treated with weekly topotecan between November 2008 and May 2012. Topotecan was given at a dose of 2.75-4 mg/m(2) via a 30-minute intravenous (IV) infusion on Days 1, 8, and 15 of a 28-day cycle until disease progression or unacceptable toxicity occurred. RESULTS Thirty-two patients were identified and 24 (75%) of them had received at least two previous regimens of chemotherapy; the median number of treatment courses was seven. The main toxicities (Grades 3 and 4) were anemia in seven (21.9%), neutropenia in six (18.8%), and thrombocytopenia in two patients (6.2%). No deaths were attributable to the therapy. Overall, seven patients (21.9%) showed a partial response (PR), while seven patients (21.9%) with stable disease (SD) were observed. Furthermore, we found a favorable response and toxicity profile in patients who received the lowest dose intensity (2.75 mg/m(2)). The median progression-free survival (PFS) and overall survival (OS) were 3 months [95% confidence interval (CI) 2.7-3.2] and 20 months (95% CI 11.1-28.9), respectively. CONCLUSION Topotecan administered as a weekly dosage (2.75-4 mg/m(2)) seems to be a tolerable regimen with modest activity in a Taiwanese population. Although the lower dose schedule showed a higher response with a better toxicity profile, further studies with more cases are needed to confirm this finding.

Histone deacetylases as new therapy targets for platinum-resistant epithelial ovarian cancer. J Cancer Res Clin Oncol 2015; 142:1659-71. [PMID: 26560874 PMCID: PMC4954831 DOI: 10.1007/s00432-015-2064-5] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2015] [Accepted: 10/20/2015] [Indexed: 12/31/2022]
Abstract
Introduction In developed countries, ovarian cancer is the fourth most common cancer in women. Due to the non-specific symptomatology associated with the disease many patients with ovarian cancer are diagnosed late, which leads to significantly poorer prognosis. Apart from surgery and radiotherapy, a substantial number of ovarian cancer patients will undergo chemotherapy and platinum based agents are the mainstream first-line therapy for this disease. Despite the initial efficacy of these therapies, many women relapse; therefore, strategies for second-line therapies are required. Regulation of DNA transcription is crucial for tumour progression, metastasis and chemoresistance which offers potential for novel drug targets. Methods We have reviewed the existing literature on the role of histone deacetylases, nuclear enzymes regulating gene transcription. Results and conclusion Analysis of available data suggests that a signifant proportion of drug resistance stems from abberant gene expression, therefore HDAC inhibitors are amongst the most promising therapeutic targets for cancer treatment. Together with genetic testing, they may have a potential to serve as base for patient-adapted therapies.

Abstract
BACKGROUND To compare the efficacy of chemotherapy (C) combined with bevacizumab (Bev) versus Bev alone in recurrent, heavily pretreated epithelial ovarian cancer (EOC). METHODS A multicenter analysis of patients treated from 2004 to 2011 was performed. Demographic, treatment, response, and adverse event information were obtained. Progression-free (PFS) and overall survival (OS) were analyzed. RESULTS Of 277 patients (median age: 58years), the majority had Stage III and IV (86%) disease, and 72% had serous histology. 244 (88%) were treated with C+Bev and 33 (12%) with Bev. Corresponding median progression-free survival (PFS) was 8.7 and 6.7months, and median overall survival (OS) was 14.3 and 10.5months, respectively. The chemotherapeutic agents combined with Bev and the median OS include: pegylated liposomal doxorubicin (n=19, OS of 20.4months), taxanes (n=55, OS of 20.2months), gemcitabine (n=106, OS of 14.1months), topotecan (n=43, OS of 13months), and cyclophosphamide (n=21, OS of 13months). There was no significant difference in toxicities between the C+Bev vs. Bev alone group. CONCLUSION This retrospective analysis supports that combination chemotherapy and bevacizumab prolongs PFS and OS compared with bevacizumab alone.

Abstract
Purpose
The purpose of this study was to evaluate the safety and efficacy of low-dose-intensity bevacizumab and weekly irinotecan as salvage treatment for patients with platinum- and taxanes-resistant advanced epithelial ovarian cancer. Methods Fifty-two patients with platinum- and taxanes-resistant advanced epithelial ovarian cancer received bevacizumab 5 mg/Kg days 1 and 15; irinotecan 60 mg/m2 days 1, 8 and 15. The combined therapy was repeated every 28 days, up to six cycles. Results A total of 230 cycles of bevacizumab combined with irinotecan were administrated to 52 patients. Among the 52 patients, 22 patients achieved partial response (42.3 %); 12 patients had stable disease (23.1 %) and 18 patients experienced disease progression (34.6 %). The median progression-free survival and the median overall survival were 8.0 months (95 % confidence interval: 6.74–9.26 months) and 13.8 months (95 % confidence interval: 11.97–15.63 months), respectively. The most frequent grade 3–4 hematologic toxicities were neutropenia (11.5 %) and thrombocytopenia (3.8 %). The non-hematologic toxicities included grade 3 diarrhea (3.8 %) and hypertension (3.8 %). Two patients (3.8 %) were confirmed with deep vein thrombosis. Febrile neutropenia, symptomatic cardiac dysfunction and gastrointestinal perforation were not observed in this study. Conclusions The combination of low-dose-intensity bevacizumab and weekly irinotecan was an effective and safe regimen for patients with platinum- and taxanes-resistant epithelial ovarian cancer.

Abstract
Chemotherapy given in a metronomic manner can be administered with less adverse effects which are common with conventional schedules such as myelotoxicity and gastrointestinal toxicity and thus may be appropriate for older patients and patients with decreased performance status. Efficacy has been observed in several settings. An opportunity to improve the efficacy of metronomic schedules without significantly increasing toxicity presents with the addition of anti-angiogenic targeted treatments. These combinations rational stems from the understanding of the importance of angiogenesis in the mechanism of action of metronomic chemotherapy which may be augmented by specific targeting of the vascular endothelial growth factor (VEGF) pathway by antibodies or small tyrosine kinase inhibitors. Combinations of metronomic chemotherapy schedules with VEGF pathway targeting drugs will be discussed in this paper.

Abstract
PURPOSE In platinum-resistant ovarian cancer (OC), single-agent chemotherapy is standard. Bevacizumab is active alone and in combination. AURELIA is the first randomized phase III trial to our knowledge combining bevacizumab with chemotherapy in platinum-resistant OC. PATIENTS AND METHODS Eligible patients had measurable/assessable OC that had progressed < 6 months after completing platinum-based therapy. Patients with refractory disease, history of bowel obstruction, or > two prior anticancer regimens were ineligible. After investigators selected chemotherapy (pegylated liposomal doxorubicin, weekly paclitaxel, or topotecan), patients were randomly assigned to single-agent chemotherapy alone or with bevacizumab (10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) until progression, unacceptable toxicity, or consent withdrawal. Crossover to single-agent bevacizumab was permitted after progression with chemotherapy alone. The primary end point was progression-free survival (PFS) by RECIST. Secondary end points included objective response rate (ORR), overall survival (OS), safety, and patient-reported outcomes. RESULTS The PFS hazard ratio (HR) after PFS events in 301 of 361 patients was 0.48 (95% CI, 0.38 to 0.60; unstratified log-rank P < .001). Median PFS was 3.4 months with chemotherapy alone versus 6.7 months with bevacizumab-containing therapy. RECIST ORR was 11.8% versus 27.3%, respectively (P = .001). The OS HR was 0.85 (95% CI, 0.66 to 1.08; P < .174; median OS, 13.3 v 16.6 months, respectively). Grade ≥ 2 hypertension and proteinuria were more common with bevacizumab. GI perforation occurred in 2.2% of bevacizumab-treated patients. CONCLUSION Adding bevacizumab to chemotherapy statistically significantly improved PFS and ORR; the OS trend was not significant. No new safety signals were observed.

Abstract
The introduction of new therapeutic agents into clinical practice of ovarian cancer, in addition to the role of surgery and chemotherapy, has been the subject of numerous studies because this tumor remains worldwide the most lethal gynecological cancer. It is now known that angiogenesis plays a vital role for ovarian physiology, but also in ovarian carcinogenesis and so it has become the main target of ovarian cancer treatment. In this review, the most common molecular pathways of angiogenesis have been investigated leading to the identification of novel targets, including monoclonal antibodies and tyrosine kinase inhibitors. The fundamental targets of anti-angiogenic drugs are vascular endothelial growth factor receptor and its ligand, but also platelet-derived growth factor, fibroblast growth factor and angiopoietin. Moreover, improved knowledge of angiogenic process allowed the discovery of other molecules, such as semaphorins, neuropilins, clusterin, some transcriptional factors, and the identification of features, including stemness, epithelial-mesenchymal transition, downregulation of certain microRNAs, the alteration of immune system, that contribute to angiogenesis and possibly to resistance mechanisms. The following patent and literature review aim to highlight recent findings of approved and novel anti-angiogenic drugs that make the treatment of patients with ovarian cancer a rapidly growing field of oncology.

Abstract
The use of liposomal delivery systems for the treatment of cancer has been extensively researched because of their passive targeting to the vasculature of solid tumors. While their potential to provide prolonged retention and high drug encapsulation is desirable for anticancer agents, a mechanistic understanding is required to optimize and design liposomal drug delivery systems capable of controllable release tailored to tumor type and patient. Topotecan (TPT) is a topoisomerase I inhibitor that undergoes reversible, pH-sensitive ring-opening hydrolysis. TPT may benefit from liposomal formulation using active loading strategies to generate low intravesicular pH to prolong drug retention and increase drug encapsulation. This paper develops a mathematical model to describe TPT's permeability as a function of pH by accounting for the drug's ionization state, membrane binding, and ring-opening interconversion kinetics. Studies were conducted to determine the acid dissociation constant of TPT's phenolic -OH and interconversion kinetics between TPT's lactone and carboxylate forms. Using the constants determined from these studies and release studies conducted at varying pH, permeability coefficients and membrane binding constants for each species of TPT were determined. Based on this model, three permeable species were observed. Interestingly, the two most permeable species were zwitterionic forms of TPT, and the permeability of the lactone zwitterion was comparable to that of the neutral form of another camptothecin analogue. Furthermore, release was affected by based-catalyzed interconversion kinetics between TPT's lactone and carboxylate forms. At neutral pH, release was rate-limited by formation of the TPT lactone from the ring-opened carboxylate form. Based on these findings, the developed model describing liposomal release of TPT may be used in the future to evaluate and optimize loading and subsequent release of liposomal TPT formulations utilizing active loading strategies.

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
OBJECTIVE We aimed to evaluate the efficacy and safety of combination bevacizumab/pemetrexed for the treatment of recurrent epithelial ovarian cancer (EOC). METHODS Platinum-sensitive or -resistant patients with recurrent or persistent EOC were eligible if they had received up to 2 prior chemotherapy regimens, including a platinum/taxane regimen without prior bevacizumab. Pemetrexed 500 mg/m(2) IV and bevacizumab 15 mg/kg IV were administered every 3 weeks. The primary endpoint was 6-month progression-free survival (PFS); other endpoints included toxicities, PFS and overall survival (OS). RESULTS Thirty-four patients received a median of 7 treatment cycles (range, 2-26). Median follow-up was 25.7 months (range, 3.0-47.2). Six month progression-free survival (PFS) was 56% (95% CI: 38-71). The following response rates were documented (%; 95% CI): 0 complete response, 14 partial responses (41%; 25-59), 18 stable disease (53%; 35-70) and 2 progressive disease (6%; 1-20). Median PFS was 7.9 months (95% CI, 4.6-10.9), with a median OS of 25.7 months (95% CI, 15.4-29.8). Twenty-two patients (64.7%) had a platinum-free interval (PFI) of >6 months prior to enrollment. Grade 3-4 hematologic toxicities included neutropenia (50%), leukopenia (26%), thrombocytopenia (12%) and anemia (9%). Non-hematologic grade 3-4 toxicities included metabolic (29%), constitutional (18%), pain (18%) and gastrointestinal (15%). Two patients developed hematologic malignancies within one year of treatment. CONCLUSIONS Combination bevacizumab/pemetrexed is an active option for both platinum-sensitive and -resistant recurrent EOC. Further investigation of cost and novel toxicities associated with this regimen may be warranted.

Tew WP, Colombo N, Ray-Coquard I, Del Campo JM, Oza A, Pereira D, Mammoliti S, Matei D, Scambia G, Tonkin K, Shun Z, Sternas L, Spriggs DR. Intravenous aflibercept in patients with platinum-resistant, advanced ovarian cancer: results of a randomized, double-blind, phase 2, parallel-arm study. Cancer 2013; 120:335-43. [PMID: 24127346 DOI: 10.1002/cncr.28406] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2013] [Revised: 08/07/2013] [Accepted: 08/22/2013] [Indexed: 12/20/2022]
Abstract
BACKGROUND In this randomized phase 2 study, the authors assessed the efficacy and safety of intravenous aflibercept at 2 different doses (2 mg/kg or 4 mg/kg) in patients with recurrent, platinum-resistant ovarian, peritoneal, or fallopian tube cancer who developed disease progression after receiving topotecan and/or pegylated liposomal doxorubicin. METHODS Patients were randomized to receive intravenous aflibercept at a dose of either 2 mg/kg or 4 mg/kg every 2 weeks until they developed disease progression or significant toxicity. The primary endpoint was to evaluate Response Evaluation Criteria in Solid Tumor response rates (overall response rate [ORR] = complete responses plus partial responses) and to test the null hypothesis (ORR, >5%). Secondary endpoints included time to tumor progression, safety, progression-free survival/overall survival, drug pharmacokinetics, and immunogenicity. In total, 67 evaluable patients per cohort were planned based on a Simon 2-stage design, and, if those patients responded, then enrollment could extend to 200 patients. Tumor radiographic response was assessed by investigators and by an independent review committee. RESULTS After the first 84 evaluable patients, 8 unconfirmed partial responders were noted (ORR, 10%) across both arms; the Independent Data Monitoring Committee recommended continuing blinded accrual. At study completion, 215 evaluable patients were accrued, including 1 responder of 106 patients (0.9%) in the 2-mg/kg cohort and 5 responders of 109 patients (4.6%) in the 4-mg/kg cohort according to the independent review committee. The clinical benefit rate (ORR plus stable disease >6 months) was 12.3% and 11% in the 2-mg/kg and 4-mg/kg cohorts, respectively. Treatment-related grade 3 and 4 adverse events included hypertension (25.5% and 27.5% in the 2-mg/kg and 4-mg/kg cohorts, respectively), proteinuria (9.4% and 7.3%, respectively), and fatigue (5.7% and 3.7%, respectively). The gastrointestinal perforation rate was low (3 patients; 1.4%). CONCLUSIONS Aflibercept at a dose of either 2 mg/kg or 4 mg/kg was generally well tolerated but did not meet the primary endpoint for response.

Abstract
Ovarian Cancer represents the most fatal type of gynecological malignancies. A number of processes are involved in the pathogenesis of ovarian cancer, especially within the tumor microenvironment. Angiogenesis represents a hallmark phenomenon in cancer, and it is responsible for tumor spread and metastasis in ovarian cancer, among other tumor types, as it leads to new blood vessel formation. In recent years angiogenesis has been given considerable attention in order to identify targets for developing effective anti-tumor therapies. Growth factors have been identified to play key roles in driving angiogenesis and, thus, the formation of new blood vessels that assist in "feeding" cancer. Such molecules include the vascular endothelial growth factor (VEGF), the platelet derived growth factor (PDGF), the fibroblast growth factor (FGF), and the angiopoietin/Tie2 receptor complex. These proteins are key players in complex molecular pathways within the tumor cell and they have been in the spotlight of the development of anti-angiogenic molecules that may act as stand-alone therapeutics, or in concert with standard treatment regimes such as chemotherapy. The pathways involved in angiogenesis and molecules that have been developed in order to combat angiogenesis are described in this paper.

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
BACKGROUND This clinical trial evaluated whether topotecan in combination with bevacizumab improved progression-free survival (PFS) in patients with advanced, refractory non--small-cell lung cancer in a second-line setting. PATIENT AND METHODS Patients aged 18 years old and older received topotecan (4.0 mg/m(2)) on days 1, 8, and 15, and bevacizumab (10 mg/kg) on days 1 and 15 as intravenous infusions on a 28-day treatment cycle. Available tumor specimens were analyzed for ISG15 gene expression as a biomarker of response to topotecan. RESULTS Forty-two patients were enrolled in the study, with a median age of 62.5 years and a median of 3 (range, 1-7) prior treatment regimens. Almost half (n = 18, 42.9%) of the patients received prior bevacizumab therapy. PFS was 5.1 months (95% CI, 3.7-7.8 months), and overall survival was 11.5 months (95% CI, 6.8-15.5 months). Response rates were as follows: 14.3% partial response, 54.8% stable disease, and 28.6% progressive disease. Hematologic toxicities included grade 3 thrombocytopenia (n = 7, 16.7%), neutropenia (n = 4, 9.5%), and anemia (n = 2, 4.8%). One toxic death occurred due to pulmonary hemorrhage, and one patient experienced a grade 4 pulmonary embolism. Grade 3 nonhematologic adverse events were uncommon (< 8%). There was a trend for improved median PFS, 3.5 months vs. 1.8 months (P = .26), in patients with high ISG15 expression. CONCLUSION Bevacizumab in combination with topotecan as a salvage therapy for metastatic non--small-cell lung cancer is well tolerated and is worthy of further investigation.

Abstract
Damage to the heart can result from both traditional chemotherapeutic agents, such as doxorubicin, and newer 'targeted' therapies, such as trastuzumab. This chemotherapeutic cardiotoxicity is potentially life-threatening and necessitates limiting or discontinuing an otherwise-effective cancer treatment. Clinical strategies focus on surveillance rather than prevention, although there are no specific therapies for this highly morbid adverse effect. Current models for prospectively predicting risk of chemotherapeutic cardiotoxicity are limited. Cardiotoxicity can occur idiosyncratically in patients without obvious demographic risk factors, suggesting a genetically determined susceptibility, and candidate-gene studies have identified a limited number of variants that increase risk. In this commentary we indicate a need for more powerful means to identify risk prospectively, and suggest that broad pharmacogenomic approaches may be fruitful.

Cost-effectiveness of early palliative care intervention in recurrent platinum-resistant ovarian cancer. Gynecol Oncol 2013; 130:426-30.

Abstract
OBJECTIVE To determine if early palliative care intervention in patients with recurrent, platinum-resistant ovarian cancer is potentially cost saving or cost-effective. METHODS A decision model with a 6 month time horizon evaluated routine care versus routine care plus early referral to a palliative medicine specialist (EPC) for recurrent platinum-resistant ovarian cancer. Model parameters included rates of inpatient admissions, emergency department (ED) visits, chemotherapy administration, and quality of life (QOL). From published ovarian cancer data, we assumed baseline rates over the final 6 months: hospitalization 70%, chemotherapy 60%, and ED visit 30%. Published data from a randomized trial evaluating EPC in metastatic lung cancer were used to model odds ratios (ORs) for potential reductions in hospitalization (OR 0.69), chemotherapy (OR 0.77), and emergency department care (OR 0.74) and improvement in QOL (OR 1.07). The costs of hospitalization, ED visit, chemotherapy, and EPC were based on published data. Ranges were used for sensitivity analysis. Effectiveness was quantified in quality adjusted life years (QALYs); survival was assumed equivalent between strategies. RESULTS EPC was associated with a cost savings of $1285 per patient over routine care. In sensitivity analysis incorporating QOL, EPC was either dominant or cost-effective, with an incremental cost-effectiveness ratio (ICER) <$50,000/QALY, unless the cost of outpatient EPC exceeded $2400. Assuming no clinical benefit other than QOL (no change in chemotherapy administration, hospitalizations or ED visits), EPC remained highly cost-effective with ICER $37,440/QALY. CONCLUSION Early palliative care intervention has the potential to reduce costs associated with end of life care in patients with ovarian cancer.

Abstract
OBJECTIVE To evaluate patterns of recurrence for ovarian, fallopian tube, and primary peritoneal cancer patients undergoing extended treatment with bevacizumab (BEV). METHODS A retrospective review of patients with primary ovarian, fallopian tube, or peritoneal cancer treated with BEV alone or in combination with other chemotherapy from 2001 to 2011 was performed. Qualified patients were identified by chemotherapy records. Electronic medical records, labs, and imaging reports were reviewed and abstracted. RESULTS Of 108 patients identified, 89 patients met study criteria by having disease progression either during treatment with BEV or after discontinuing BEV without initiating any other treatment. Patients on extended BEV therapy (>12 cycles) were more likely to recur in extra-visceral sites (p=0.04), especially in lymph nodes (p=0.0002), and presented with fewer symptoms at time of recurrence (p=0.02), compared to patients who had received ≤ 12 cycles. CA-125 becomes less reliable for the detection of recurrent disease with extended BEV therapy (p=0.03 for ≤12 cycles vs. p=0.08 for >12 cycles). Radiology was superior to CA-125, symptom, and physical exam, in detecting recurrence with extended BEV therapy (all p<0.0001). CONCLUSIONS Extended treatment with BEV in ovarian, fallopian tube, and peritoneal cancers results in alterations in the patterns of recurrence. Radiologic imaging is more reliable than CA-125, symptoms, or physical exam, in identifying recurrent disease in patients undergoing BEV treatment. As novel targeted therapies continue to be employed, guidelines for gynecologic cancer surveillance must continue to be reexamined.

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
BACKGROUND Topotecan is currently the only US Federal Drug Administration (FDA)-approved drug for second-line treatment of relapsed small-cell lung cancer (SCLC). We investigated the efficacy and safety of a novel topotecan-bevacizumab combination in treating relapsed SCLC. PATIENTS AND METHODS Each 21-day treatment cycle consisted of bevacizumab (15 mg/kg) administration on day 1 and oral topotecan (2.3 mg/m(2)/d) administration on days 1 to 5. Treatment was continued for 8 cycles or until disease progression/toxicity. The primary objective was evaluation of 3-month progression-free survival (PFS). Overall response rate (ORR), duration of response, time to response (TTR), and overall survival (OS) were secondary objectives. RESULTS The study enrolled 50 patients between July 2008 and May 2010. The 3-month PFS was 65% (95% confidence interval [CI], 49.3%-76.9%), which was promising compared with the historical control of 50% (P = .017) but did not meet the predefined criteria for clinically meaningful improvement. Median PFS was 6.24 months for the sensitive subgroup (progression time from end of previous chemotherapy > 90 days; n = 27) and 2.91 months for the resistant subgroup (progression time ≤ 90 days; n = 23). No patient achieved complete response (CR), and the ORR was 16%. Twenty (40%) patients had stable disease (SD) and 13 (26%) had progressive disease (PD). Median OS, TTR, and duration of response were 7.4, 1.3, and 4.7 months, respectively. The worst reported adverse events (AEs) were grade 1/2 in 11 (22%) patients and grade 3/4/5 in 39 (78%) patients. CONCLUSION Improvement in the 3-month PFS after treatment with topotecan-bevacizumab was promising compared with the historical control and justifies additional studies with this regimen.

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.

Abstract
INTRODUCTION Ovarian cancer remains the most lethal gynecologic malignancy. Although standard platinum-based chemotherapy results in high response rates, more than 70% of patients with advanced disease will experience recurrence within 5 years. Therefore, novel treatment strategies to increase primary efficacy, decrease recurrence after primary treatment and improve the response rate for recurrent disease are needed. AREAS COVERED This review covers antiangiogenesis therapy and the efficacy of bevacizumab as primary treatment and in platinum-sensitive and resistant recurrent disease. EXPERT OPINION The evidence provided from Phase III trials has supported the efficacy of bevacizumab in primary and recurrent ovarian cancer management. Future investigation is needed to improve clinical performance (via biomarkers of efficacy, early discontinuation, additional agents, etc.), as well as, more sensitive tools to assess direct patient impact.

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
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
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
BACKGROUND The addition of bevacizumab to standard chemotherapy prolongs progression free survival in the first line treatment of epithelial ovarian cancer (EOC), but its cost/effectiveness is debated. We assessed the safety and activity of a lower dose of bevacizumab in pretreated advanced stage EOC. METHODS We treated 15 patients, mostly with platinum resistant EOC, who had received a median of four prior cytotoxic regimens, with bevacizumab 5-7.5 mg/kg q21 days in combination with either carboplatin (n = 8), oral cyclofosfamide (n = 5) or weekly paclitaxel (n = 2). Bevacizumab was administered until disease progression. Tumor response was assessed by CA125 and fusion 18 F-FDG PET/contrast enhanced CT. RESULTS The median number of bevacizumab cycles was 21 (range 3-59). The median baseline CA125 was 272 U/ml and decreased to 15.2 U/ml at nadir. Tumor response was 4 complete response (CR) (26.7%) and 7 partial response (PR) (46.7%) by chemotherapy (CT), with an overall response rate of 73.4% (95% CI, 51.0 - 95.8) according to Response Evaluation Criteria In Solid Tumors (RECIST), and 6 CR (40%) and 4 PR (26.7%) by PET, for an overall metabolic response rate of 67% (95%CI, 42.8 - 90.6) according to PET Response Criteria in Solid Tumors (PERCIST). Median progression free survival (PFS) was 21 months and median overall survival (OS) was 24 months. Grade 3 adverse events related to bevacizumab were hypertension (n = 2), proteinuria (n = 1) and epistaxis (n = 5). Treatment was delayed in five patients for nasal bleeding or uncontrolled hypertension. CONCLUSIONS Low-dose bevacizumab and chemotherapy was well tolerated and active in a heavily pretreated population of advanced EOC. Further studies should assess the activity of low dose bevacizumab in EOC.

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
Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor which has been used in conjunction with other anti-cancer agents in the treatment of patients with many cancers. It remains controversial whether bevacizumab can prolong survival in cancer patients. This meta-analysis was therefore performed to evaluate effect of bevacizumab on survival in cancer patients. PubMed, EMBASE, and Web of Science databases were searched for English-language studies of randomized controlled trials comparing bevacizumab with control therapy published through February 8, 2012. Progression-free survival, overall survival, and one-year survival rate were analyzed using random- or fixed-effects model. Thirty one assessable randomized controlled trials were identified. A significant improvement in progression-free survival in cancer patients was attributable to bevacizumab compared with control therapy (hazard ratio, 0.72; 95% confidence interval, 0.68 to 0.76; p<0.001). Overall survival was also significantly longer in patients were treated with bevacizumab (hazard ratio, 0.87; 95% confidence interval, 0.83 to 0.91; p<0.001). The significant benefit in one-year survival rate was further seen in cancer patients receiving bevacizumab (odds ratio, 1.30; 95% confidence interval, 1.20 to 1.41; p<0.001). Current evidences showed that bevacizumab prolong progression-free survival and overall survival, and increase one-year survival rate in cancer patients as compared with control therapy.

Abstract
Hypoxia inducible factor-1α (HIF-1α) stimulates expression of genes associated with angiogenesis and is associated with poor outcomes in ovarian and other cancers. In normoxia, HIF-1α is ubiquitinated and degraded through the E3 ubiquitin ligase, von Hippel-Lindau; however, little is known about the regulation of HIF-1α in hypoxic conditions. FBW7 is an E3 ubiquitin ligase that recognizes proteins phosphorylated by glycogen synthase kinase 3β (GSK3β) and targets them for destruction. This study used an ovarian cancer cell model to test the hypothesis that HIF-1α phosphorylation by GSK3β in hypoxia leads to interaction with FBW7 and ubiquitin-dependent degradation. Expression of constitutively active GSK3β reduced HIF-1α protein and transcriptional activity and increased ubiquitination of HIF-1α in hypoxia, whereas pharmacologic inhibition of GSK3 or expression of siGSK3β promoted HIF-1α stabilization and activity. A mechanism through FBW7 was supported by the observed decrease in HIF-1α stabilization when FBW7 was overexpressed and both the elevation of HIF-1α levels and decrease in ubiquitinated HIF-1α when FBW7 was suppressed. Furthermore, HIF-1α associated with FBW7γ by co-immunoprecipitation, and the interaction was weakened by inhibition of GSK3 or mutation of GSK3β phosphorylation sites. The relevance of this pathway to angiogenic signaling was supported by the finding that endothelial cell tube maturation was increased by conditioned media from hypoxic SK-OV-3 cell lines expressing suppressed GSK3β or FBW7. These data introduce a new mechanism for regulation of HIF-1α during hypoxia that utilizes phosphorylation to target HIF-1α for ubiquitin-dependent degradation through FBW7 and may identify new targets in the regulation of angiogenesis.

Abstract
PURPOSE OF REVIEW Vascular endothelial growth factor (VEGF), one of the major pathways involved in tumor angiogenesis, is often overexpressed in epithelial ovarian cancer (EOC), and therefore an attractive target for therapy. This review aims to evaluate the rationale for targeting angiogenic pathways by the usage of the anti-VEGF agent bevacizumab in EOC. RECENT FINDINGS Bevacizumab monotherapy has been shown to be effective in the treatment of EOC with response rate of 16-21% in phase II trials. In phase III trials, patients with advanced EOC who received combination chemotherapy (paclitaxel + carboplatin) plus bevacizumab with maintenance bevacizumab had significantly longer progression-free survival than those who received chemotherapy alone, but did not prolong overall survival. The most common grade 3/4 adverse events of bevacizumab monotherapy include hypertension and proteinuria, while heavily pretreated patients were at increased risk of bowel perforation. The addition of bevacizumab to the standard chemotherapy in patients with advanced EOC may not be cost-effective. SUMMARY Bevacizumab has significant activity and is the most promising drug in EOC. However, understanding of its unique adverse events and identification of predictive biomarkers of bevacizumab response are necessary in order to select patients most likely to benefit from this therapy.
