[PMID: 39129672 DOI: 10.1080/14796694.2024.2373680] [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: 11/17/2023] [Accepted: 05/31/2024] [Indexed: 08/13/2024] Open
Abstract
Aim: Vascular endothelial growth factor receptor inhibitors (VEGFRIs) have been common used for recurrent ovarian cancer (ROC), but insufficient high-level evidence on verifying its efficacy and safety. Methods: Randomized controlled trials (RCTs) were searched under eight electronic databases. Stata 14.0 and Review Manager 5.3 were used for data analysis. Certainty of the evidence was assessed using the GRADE profiler. This systematic review (SR) was registered under INPLASY (INPLASY202120019). Conclusion: Totally 23 RCTs involving 2810 patients were included in this SR. Current evidence revealed that VEGFRIs had better efficacy, survival and quality of life in the treatment of ROC. Though VEGFRIs increase some drug-related adverse events (AEs), all the AEs could be manageable in the clinical practice.

[PMID: 36375738 DOI: 10.1016/j.drudis.2022.103438] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 10/27/2022] [Accepted: 11/08/2022] [Indexed: 11/13/2022]
Abstract
Angiogenesis and metastasis are two interdependent cancer hallmarks, the latter of which is the key cause of treatment failure. Thus, establishing effective antiangiogenesis/antimetastasis agents is the final frontier in cancer research. Gold nanoparticles (GNPs) may provide disruptive advancements in this regard due to their intrinsic physical and physiological features. Here, we comprehensively discuss recent potential therapeutical strategies to treat angiogenesis and metastasis and present a critical review on the state-of-the-art in vitro and in vivo evaluations of the antiangiogenic/antimetastatic activity of GNPs. Finally, we provide perspectives on the contribution of GNPs to the advancement of cancer management.

Developing and validating a prognostic nomogram for ovarian clear cell carcinoma patients: A retrospective comparison of lymph node staging schemes with competing risk analysis. Front Oncol 2022; 12:940601. [DOI: 10.3389/fonc.2022.940601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 10/14/2022] [Indexed: 11/11/2022] Open
Abstract
PurposeLymph node (LN) involvement is a key factor in ovarian clear cell carcinoma (OCCC) although, there several indicators can be used to define prognosis. This study examines the prognostic performances of each indicator for OCCC patients by comparing the number of lymph nodes examined (TNLE), the number of positive lymph nodes (PLN), lymph node ratio (LNR), and log odds of metastatic lymph nodes (LODDS).Methods1,300 OCCC patients who underwent lymphadenectomy between 2004 and 2015 were extracted from the Surveillance Epidemiology and End Results (SEER) database. Primary outcomes were Overall Survival (OS) and the cumulative incidence of Cancer-Specific Survival (CSS). Kaplan–Meier’s and Fine-Gray’s tests were implemented to assess OS and CSS rates. After conducting multivariate analysis, nomograms using OS and CSS were constructed based upon an improved LN system. Each nomograms’ performance was assessed using Receiver Operating Characteristics (ROC) curves, calibration curves, and the C-index which were compared to traditional cancer staging systems.ResultsMultivariate Cox’s regression analysis was used to assess prognostic factors for OS, including age, T stage, M stage, SEER stage, and LODDS. To account for the CSS endpoint, a proportional subdistribution hazard model was implemented which suggested that the T stage, M stage, SEER stage, and LNR are all significant. This enabled us to develop a LODDS-based nomogram for OS and a LNR-based nomogram for CSS. C-indexes for both the OS and CSS nomograms were higher than the traditional American Joint Committee on Cancer (AJCC), 8th edition, staging system. Area Under the Curve (AUC) values for predicting 3- and 5-year OS and CSS between nomograms also highlighted an improvement upon the AJCC staging system. Calibration curves also performed with consistency, which was verified using a validation cohort.ConclusionsLODDS and LNR may be better predictors than N stage, TNLE, and PLNs. For OCCC patients, both the LODDS-based and LNR-based nomograms performed better than the AJCC staging system at predicting OS and CSS. However, further large sample, real-world studies are necessary to validate the assertion.

Abstract
Given the special microenvironment of solid tumors, live microorganisms have emerged as drug delivery vehicles and therapeutic agents. Here, an acid-induced therapeutic platform is constructed using attenuated Escherichia coli to express the cytolysin A protein. The bacteria can target and colonize tumor tissues without causing notable host toxicity. Bacterial infection can disrupt blood vessels and trigger thrombosis in tumor tissues, resulting in the cut-off of nutrient supply to tumor cells and the arrest of tumor growth. The expression of cytolysin A induced by the acidic tumor microenvironment further strengthens thrombosis and provides a complementary therapeutic option due to its pore-forming function. In a xenograft mouse tumor model, this strategy reduces tumor proliferation by 79% and significantly prevents tumor metastasis, thus paving a new avenue for bacteria-based tumor therapy.

Abstract
This paper proposes a representation learning framework HE-LSTM model for heterogeneous temporal events, which can automatically adapt to the multiscale sampling frequency of multisource heterogeneous data. The proposed model also demonstrates its superiority over other typical approaches on real data sets. A controlled study is performed according to computerized randomization, with 38 patients in each of the two groups. The study group has a higher resuscitation success rate and patient satisfaction than the conventional group (P < 0.05), and the time from the first consultation to the completion of the first ECG, the time from the completion of the ECG to the activation of the path lab, and the time from the emergency admission to the balloon dilation were significantly shorter in the study group than in the conventional group (P < 0.05). The emergency care process reengineering intervention helps patients with acute myocardial infarction to be treated quickly and effectively, thus improving their resuscitation success rate and satisfaction rate, and is worthy to be caused in the clinic and widely applied.

Abstract
Cerebral haemorrhage is a serious subtype of stroke, with most patients experiencing short-term haematoma enlargement leading to worsening neurological symptoms and death. The main hemostatic agents currently used for cerebral haemorrhage are antifibrinolytics and recombinant coagulation factor VIIa. However, there is no clinical evidence that patients with cerebral haemorrhage can benefit from hemostatic treatment. We provide an overview of the mechanisms of haematoma expansion in cerebral haemorrhage and the progress of research on commonly used hemostatic drugs. To improve the semantic segmentation accuracy of cerebral haemorrhage, a segmentation method based on RGB-D images is proposed. Firstly, the parallax map was obtained based on a semiglobal stereo matching algorithm and fused with RGB images to form a four-channel RGB-D image to build a sample library. Secondly, the networks were trained with 2 different learning rate adjustment strategies for 2 different structures of convolutional neural networks. Finally, the trained networks were tested and compared for analysis. The 146 head CT images from the Chinese intracranial haemorrhage image database were divided into a training set and a test set using the random number table method. The validation set was divided into four methods: manual segmentation, algorithmic segmentation, the exact Tada formula, and the traditional Tada formula to measure the haematoma volume. The manual segmentation was used as the "gold standard," and the other three algorithms were tested for consistency. The results showed that the algorithmic segmentation had the lowest percentage error of 15.54 (8.41, 23.18) % compared to the Tada formula method.

Abstract
Recent advances in the development of multitarget tyrosine kinase inhibitors (MTKIs), which mainly target the vascular endothelial growth factor receptor (VEGFR), have improved prognoses and dramatically changed the treatment strategy for advanced thyroid cancer. However, adverse events related to this inhibition can interrupt treatment and sometimes lead to discontinuation. In addition, they can be annoying and potentially jeopardize the subjects' quality of life, even allowing that the clinical outcome of patients with advanced thyroid cancer remains limited. In this review, we summarize the potential mechanisms underlying these adverse events (hypertension, proteinuria and renal impairment, hemorrhage, fistula formation/gastrointestinal perforation, wound healing, cardiovascular toxicities, hematological toxicity, diarrhea, fatigue, and acute cholecystitis), their characteristics, and actual management. Furthermore, we also discuss the importance of related factors, including alternative treatments that target other pathways, the necessity of subject selection for safer administration, and patient education.

Abstract
Nanoparticulate drug delivery systems (nano-DDSs) are required to reliably arrive and persistently reside at the tumor site with minimal off-target side effects for clinical theranostics. However, due to the complicated environment and high interstitial pressure in tumor tissue, they can return to the bloodstream and cause secondary side effects in normal organs. Recently, a number of nanogatekeepers have been engineered via structure-transformable/stable strategies to overcome this undesirable dilemma. The emerging structure-transformable nanogatekeepers for tumor imaging and therapy are first overviewed here, particularly for nanogatekeepers undergoing structural transformation in tumor microenvironments, cell membranes, and organelles. Thereafter, intelligent structure-stable nanogatekeepers through reversible activation and artificial individualization receptors are overviewed. Finally, the ongoing challenges and prospects of nanogatekeepers for clinical translation are briefly discussed.

Risk of Thrombo-Embolic Events in Ovarian Cancer: Does Bevacizumab Tilt the Scale? A Systematic Review and Meta-Analysis. Cancers (Basel) 2021; 13:cancers13184603. [PMID: 34572830 PMCID: PMC8464807 DOI: 10.3390/cancers13184603] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 09/08/2021] [Accepted: 09/12/2021] [Indexed: 12/21/2022] Open
Abstract
Simple Summary Thromboembolic events (TEs) are the second cause of death in cancer patients. Two forms of thromboembolic events may arise: arterial, such as ischemic stroke or myocardial infarction; and venous, such as deep vein thrombosis or pulmonary embolism. Bevacizumab is a monoclonal antibody directed against vascular endothelial-derived growth factor, and is widely used in advanced ovarian cancer. However, whether bevacizumab increases the risk of thromboembolic events in ovarian cancer is matter of debate since studies have shown conflicting results. In our systematic review and meta-analysis, we included 14 trials with bevacizumab in ovarian cancer. We found that the risk of arterial thromboembolic events more than doubled with a risk ratio of 2.45. Also the risk of venous thromboembolism increased 30% with bevacizumab treatment. Bevacizumab, therefore, can be considered an additional risk factor for selecting patients for primary prophylaxis with anticoagulants. Abstract Thromboembolic events are the second cause of death in cancer patients. In ovarian cancer, 3–10% of patients present with venous thromboembolism (VTE), but the incidence may rise to 36% along the disease course. Bevacizumab is a monoclonal antibody directed against vascular endothelial-derived growth factor, and in in vitro studies it showed a predisposition to hemostasis perturbation, including thrombosis. However, in vivo and clinical studies have shown conflicting results for its use as a treatment for ovarian cancer, so we conducted a systematic review and meta-analysis on the risk of arterial thromboembolism (ATE) and VTE in ovarian cancer patients treated with bevacizumab. The review comprised 14 trials with 6221 patients: ATE incidence was reported in 5 (4811 patients) where the absolute risk was 2.4% with bevacizumab vs. 1.1% without (RR 2.45; 95% CI 1.27–4.27, p = 0.008). VTE incidence was reported in 9 trials (5121 patients) where the absolute risk was 5.4% with bevacizumab vs. 3.7% without (RR 1.32; 95% CI 1.02–1.79, p = 0.04). Our analysis showed that the risk of arterial and venous thromboembolism increased in patients treated with bevacizumab. Thrombolic events (TEs) are probably underreported, and studies should discriminate between ATE and VTE. Bevacizumab can be considered as an additional risk factor when selecting patients for primary prophylaxis with anticoagulants.

Abstract
BACKGROUND Approach to the management of early stage cervical cancers with tumor size >2 cm in women who desire fertility preservation has been fraught with controversy. Fertility sparing surgery for FIGO 2018 stage IB cancers has been validated most for tumors ≤2 cm. In this review, our objective was to evaluate the oncologic and obstetric outcomes for women that underwent neoadjuvant chemotherapy (NACT) before fertility sparing surgery for tumors 2-4 cm. METHODS We performed a systematic literature review and searched PubMed, Google Scholar, Cochrane Reviews and UpToDate (from January 2000 to February 2021) using the terms: cervical cancer, fertility preservation, trachelectomy, radical trachelectomy, neoadjuvant chemotherapy, cervical cancer treatment, stage IB1 or IB2 cervical cancer, and cervical cancer size 2-4 cm. We included manuscripts with information on patients with tumor sizes 2-4 cm, lymph node status, follow-up, obstetric and oncologic outcome. We excluded review articles or articles without all pertinent patient information. RESULTS Eighteen articles were identified including 249 patients. For final analysis, 114 met inclusion criteria. All included patients had FIGO 2018 stage IB2 cervical cancer, underwent neoadjuvant chemotherapy and subsequent fertility sparing surgery. Vaginal radical trachelectomy, cold knife conization, abdominal radical trachelectomy, laparoscopic radical trachelectomy, simple vaginal trachelectomy, and cone laser were performed in 46 (40.4%), 26 (22.8%), 14 (12.3%), 13 (11.4%), 8 (7%), and 7 (6.1%) women, respectively. The most common regimen of chemotherapy was platinum-based therapy with cisplatin. The follow-up time reported in all studies ranged from 1 to 225 months. Of 64 attempted pregnancies, there were 49 (76.6%) viable deliveries which included 6 preterm births (9.4%). The recurrence rate was 6.1% and two patients (1.8%) died of disease. CONCLUSION Fertility sparing surgery following NACT is an option for women with cervical cancers that are 2-4 cm that wish to preserve fertility without sacrificing oncologic or obstetric outcomes. Confirmation of these findings are anticipated from an ongoing international phase II clinical trial [1].

Abstract
To overcome drug resistance in relapsed ovarian cancer, an isolated perfusion system was used to generate a higher local exposure to cytostatic drugs. In addition to cisplatin as the cytostatic agent of choice, the present study combined adriamycin and mitomycin in a three drugs regime due to their increased cytotoxicity under hypoxia. A total of 107 patients, including 87 patients with relapses after previous platinum-containing therapies, 46 stage IIIC and 41 stage IV cases, were enrolled in the present study. A total of 25 patients were chemonaive, including 20 stage IIIC. The systemically pretreated patients in stage IIIC survived a median of 12.8 months, and those in stage IV 10.9 months. The overall clinical response rate of stages IIIC and IV combined was 69%. A complete decrease in ascites was found in 43% of all patients, a significant reduction in 19%. Toxicity and side effects were very mild and the bone marrow suppression was mostly grade I and never exceeded grade II. The primary clinical symptom in patients with post-therapeutic tumor necrosis, which occurred in 10-15% of all cases, was fever, fatigue and poor performance. The isolated hypoxic abdominal perfusion treatment is a potent instrument to break an existing chemoresistance without significant side effects with a good quality of life and comparatively long survival time.

Abstract
Although vascular disrupting agents (VDAs) have been extensively implemented in current clinical tumor therapy, the notable adverse events caused by long-term dosing severely limit the therapeutic efficacy. To improve this therapy, we report a strategy for VDA-induced aggregation of gold nanoparticles to further destroy tumor vascular by photothermal effect. This strategy could effectively disrupt tumor vascular and cut off the nutrition supply after just one treatment. In the murine tumor model, this strategy results in notable tumor growth inhibition and gives rise to a 92.7% suppression of tumor growth. Besides, enhanced vascular damage could also prevent cancer cells from distant metastasis. Moreover, compared with clinical therapies, this strategy still exhibits preferable tumor suppression and metastasis inhibition ability. These results indicate that this strategy has great potential in tumor treatment and could effectively enhance tumor vascular damage and avoid the side effects caused by frequent administration.

Hypertension and incident cardiovascular events following ibrutinib initiation. Blood 2020; 134:1919-1928. [PMID: 31582362 DOI: 10.1182/blood.2019000840] [Citation(s) in RCA: 151] [Impact Index Per Article: 37.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Accepted: 07/26/2019] [Indexed: 12/12/2022] Open
Abstract
Ibrutinib is associated with dramatic efficacy against B-cell malignancies. Yet, it has been linked with potentially limiting cardiotoxicity, including emerging reports of profound hypertension (HTN). The long-term incidence, severity, and impact of HTN development with ibrutinib are unknown. Therefore, in 562 consecutive patients treated with ibrutinib for B-cell malignancies from 2009 through 2016, we assessed the new/incident or worsened HTN (systolic blood pressure [BP] cutoff, 130 mm Hg). Observed incident HTN rates were compared with Framingham-heart-predicted incident HTN rates. We also evaluated the relationship of HTN to the development of other major adverse cardiovascular events (MACEs), including arrhythmia, myocardial infarction, stroke, heart failure, and cardiovascular death. Further, we assessed the effects of different antihypertensive classes on ibrutinib-related HTN. Overall, 78.3% of ibrutinib users developed new or worsened HTN over a median of 30 months. New HTN developed in 71.6% of ibrutinib users, with a time to 50% cumulative incidence of 4.2 months. Among those without preceding HTN, 17.7% developed high-grade HTN (BP >160/100 mm Hg). In multivariate regression, new or worsened HTN was associated with increased MACEs (hazard ratio [HR], 2.17; 95% confidence interval [CI], 1.08-4.38). No single antihypertensive class was associated with prevention or control of ibrutinib-related HTN. However, antihypertensive initiation was associated with a lower risk of a MACE (HR, 0.40; 95% CI, 0.24-0.66). Collectively, these data suggest that ibrutinib is associated with a substantial increase in the incidence and severity of HTN, and that HTN development carries a higher risk of subsequent cardiotoxic events.

Abstract
Cancer remains a major and leading health problem worldwide. Lack of early diagnosis, chemoresistance, and recurrence of cancer means vast research and development are required in this area. The complexity of the tumor microenvironment in the biological milieu poses greater challenges in having safer, selective, and targeted therapies. Existing strategies such as chemotherapy, radiotherapy, and antiangiogenic therapies moderately improve progression-free survival; however, they come with side effects that reduce quality of life. Thus, targeting potential candidates in the microenvironment, such as extracellular cathepsin D (CathD) which has been known to play major pro-tumorigenic roles in breast and ovarian cancers, could be a breakthrough in cancer treatment, specially using novel treatment modalities such as immunotherapy and nanotechnology-based therapy. This chapter discusses CathD as a pro-cancerous, more specifically a proangiogenic factor, that acts bi-functionally in the tumor microenvironment, and possible ways of targeting the protein therapeutically.

Abstract
In order to break through drug resistance in platinum-refractory ovarian cancer, augmented drug exposure was administered to the abdomen by means of an isolated perfusion system. Four cycles of isolated hypoxic abdominal perfusion with cisplatin, adriamycin, and mitomycin were conducted in 4-week intervals. Cisplatin and adriamycin were chosen because of their increased cytotoxicity under hypoxic conditions. Chemofiltration was performed for prophylaxis of cumulative toxicity of adriamycin and mitomycin. The study included 45 patients with recurrent epithelial ovarian cancer who had prior platinum containing therapies (3, stage Federation of Gynecology and Obstetrics (FIGO) IIIB; 20, stage FIGO IIIC; 22; stage FIGO IV). The median survival rate in stage FIGO IIIBC was 12 months, and in stage IV was 10 months. The tumor marker decreased to complete response or partial response at 17.8% and 55.6% of the patients. CT or MRI visualization showed complete response in 4.1%, and partial response was in 54.1%. Complete resolution of ascites was noted in 30% of cases and substantial reduction in another 43%. Toxicity was generally low. Quality of life was improved in the majority of cases. Bone-marrow suppression ranged between WHO grade 1 and 2, and in patients with previous third- or fourth-line chemotherapy, it was WHO grade 3. Isolated hypoxic abdominal perfusion with chemofiltration for patients with progressive and platinum-refractory stage III and IV ovarian cancer is an effective therapy, breaking through chemoresistance and offering comparably long survival at good quality of life.

Abstract
Background New treatment options for metastasised high-grade serous carcinoma (HGSC) are urgently needed. HGSC frequently metastasises to the omentum, inducing angiogenesis in the local omental microvasculature to facilitate tumour growth. We previously showed that HGSC-secreted cathepsin L (CathL) induces pro-angiogenic changes in disease relevant human omental microvascular endothelial cells (HOMECs), suggesting a role in tumour angiogenesis. Here we investigate whether CathL acts by inducing local production of the carbohydrate-binding protein galectin-1 (Gal1), which has been reported to be involved in tumourigenesis in other tumours. Methods HOMECs were used for all experiments. Gal1 mRNA and protein levels were measured by RT-PCR and ELISA respectively. Gal1-induced cell proliferation was assessed using WST-1 assay, migration using a transwell assay and in vivo Gal1 expression by immunohistochemistry. Results CathL transcriptionally regulated HOMEC production and secretion of Gal1 via activation of NFκB (significantly inhibited by sulfasalazine). Gal1 significantly enhanced HOMEC migration (p < 0.001) and proliferation (p < 0.001), suggesting an autocrine action. The latter was significantly reduced by the MEK/ERK1/2 inhibitors U0126 and PD98059 suggesting downstream activation of this pathway. Immunohistochemical analysis of omenta from HGSC patients with or without metastatic disease demonstrated a positive correlation between Gal1 expression and number of microvessels (r = 0.8702, p < 0.001), and area of vessels (r = 0.7283, p < 0.001), supporting a proangiogenic role for Gal1 in omental metastases. Conclusion HOMEC Gal1 transcription and release in response to CathL secreted from metastasising HGSC acts in an autocrine manner on the local microvasculature to induce pro-angiogenic changes, highlighting a potential new therapeutic target.

Abstract
Lenvatinib is a multikinase inhibitor of vascular endothelial growth factor (VEGF) receptors 1-3, fibroblast growth factor receptors 1-4, RET, KIT, and platelet-derived growth factor receptor-α. Lenvatinib is approved as a monotherapy for the treatment of radioiodine-refractory differentiated thyroid cancer and in combination with everolimus for the second-line treatment of advanced renal cell carcinoma. Lenvatinib is also under investigation for the treatment of several malignancies including unresectable hepatocellular carcinoma. Although lenvatinib is associated with favorable efficacy, it is associated with adverse events (AEs) that the clinician will have to closely monitor for and proactively manage. Most of these AEs are known class effects of VEGF-targeted therapies, including hypertension, diarrhea, fatigue or asthenia, decreased appetite, and weight loss. This review summarizes the safety profile of lenvatinib and offers guidance for the management of both frequent and rare AEs. We discuss the potential mechanisms underlying these AEs and present practical recommendations for managing toxicities. The development of treatment plans that include prophylactic and therapeutic strategies for the management of lenvatinib-associated AEs has the potential to improve patient quality of life, optimize adherence, minimize the need for dose reductions, treatment interruptions, or discontinuations, and maximize patient outcomes.

Abstract
Purpose Carboplatin is a first-line treatment for ovarian cancer. However, most patients develop resistance and undergo disease recurrence. This study aims to explore the relationship between the expression of X-linked inhibitor of apoptosis protein (XIAP) and carboplatin sensitivity in ovarian cancer. Patients and methods We examined the expression of XIAP in ovarian cancer by immuno-chemistry. Next, we investigated the role of XIAP in regulating carboplatin sensitivity in ovarian cancer ES2 and 3AO cells through Cell Counting Kit-8 cell viability assay and fluorescein isothiocyanate-Annexin V/propidium iodide apoptosis assay. Expression of apoptotic effectors was measured by Western blot. Results The immunochemistry results showed that high XIAP expression levels inversely correlated with carboplatin response (P=0.03) and progression-free survival (P=0.0068) in patients with ovarian cancer. Knockdown of XIAP repressed the cell viabilities in the carboplatin-treated cells and increased carboplatin-induced caspase activation. In summary, our data show that XIAP mediates carboplatin sensitivity of ovarian cancer. Conclusion In summary, our data show that XIAP mediates carboplatin sensitivity of ovarian cancer and XIAP may be a novel target for the treatment of carboplatin-resistant ovarian cancer.

Abstract
BACKGROUND Angiogenesis inhibitors are a standard first-line treatment for metastatic colorectal cancer. Anal canal pain is a common adverse event, but its cause has never been described. The aim of the study was to evaluate the association between the use of angiogenesis inhibitors and symptomatic anal ulcer development. METHODS This retrospective cohort study included all 601 consecutive metastatic colorectal cancer patients undergoing first line treatment from January 2010 to June 2016 at the Veneto Institute of Oncology. Details about patient characteristics, treatment and proctology reports were retrieved and compared. Vascularization of the anal canal was evaluated with contrast MRI. RESULTS Fifty out of 601 patients reported perianal complaints during treatment and underwent proctologic evaluation. Among those, 16 were found to have an anal ulcer. Symptomatic anal ulcers occurred only in patients receiving bevacizumab (4.2% vs. 0% with other regimens, p = .009). The peak incidence was 4-8 weeks after treatment start. Vascularization of anal canal was significantly lower in patients treated with bevacizumab (p = .03). Hypertension and hemorrhoids were associated with a lower risk of anal ulcer occurrence (p = .009 and p = .036). Pain intensity was severe. All attempts at symptomatic treatment only led to transient benefit. The absence of symptomatic ulcers was protective against earlier permanent discontinuation of treatment (HR = .22, 95%CI: 0.04-0.62). CONCLUSIONS The development of symptomatic anal ulcers in patients receiving angiogenesis inhibitor is a common adverse event which can compromise the continuation of cancer therapy. We recommend an early proctologic evaluation in case of anal symptoms with the aim to prevent and timely manage such complication.

Abstract
Improvements in cancer therapy have enabled further insight into the long-term effects of treatment, including the highly prevalent gonadal failure. The focus of treatment has been shifted to the preservation of fertility, which may be achieved by preventing ovarian toxicity. To this end, new molecular-targeted agents, including monoclonal antibodies, have been developed and used in a standard procedure for managing different cancers. However, the prolonged antitumor activity of these drugs may cause the emergence of new toxic effects. The aim of the present review was to discuss the leading toxic effect of the anti-angiogenic agent bevacizumab on ovarian function in female patients of reproductive age, which may be observed and expected during in clinical practice. The majority of bevacizumab-induced side effects are expected to be transient and eliminated within the anticipated drug clearance time frame; however, fundamental investigations on these effects are required for generating more evidence-based practice guidelines.

Abstract
INTRODUCTION Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor (VEGF). (Avastin; Genetech, Inc, San Francisco, CA) Angiogenesis is blocked by the binding of bevacizumab to VEGF, inhibiting the binding of this ligand to the VEGF receptor. On 14 August 2014 the Food and Drug Administration (FDA) approved use of bevacizumab in persistent, recurrent, or metastatic cervical cancer. Areas covered: Herein we review pharmacodynamics and kinetics, clinical data and treatment-related toxicities of bevacizumab in the treatment of metastatic, recurrent or persistent cervical cancer. Additionally, future areas of development are reviewed. Expert commentary: Anti-angiogenesis therapy with bevacizumab is central to metastatic, persistent, and recurrent cervical cancer treatment. Additional anti-angiogenesis drugs are in development. Future studies will need to establish if the addition of multiple anti-angiogenesis agents or anti-angiogenesis in combination with immunotherapy is more effective than bevacizumab with chemotherapy.

Abstract
VEGF inhibitors, including receptor tyrosine kinase inhibitors, are used as adjunct therapies in a number of cancer treatments. An emerging issue with these drugs is that most cause hypertension. To gain insight into the physiological mechanisms involved, we evaluated their regional hemodynamic effects in conscious rats. Male Sprague Dawley rats (350–450 g) were chronically implanted with pulsed Doppler flow probes (renal and mesenteric arteries, and the descending abdominal aorta) and catheters (jugular vein, peritoneal cavity, and distal abdominal aorta). Regional hemodynamics were measured over 4 d, before and after daily administration of cediranib (3 and 6 mg/kg, 3 and 6 mg/kg/h for 1 h, i.v.), sorafenib (10 and 20 mg/kg, 10 and 20 mg kg/h for 1 h, i.v.), pazopanib (30 and100 mg/kg, i.p.), or vandetanib (12.5 and 25 mg/kg, i.p.). All drugs evoked significant increases (P < 0.05; n = 7–8) in mean arterial pressure, which were generally accompanied by significant mesenteric and hindquarters, but not renal, vasoconstrictions. The hypertensive effects of cediranib were unaffected by losartan (10 mg/kg/h), bosentan (20 mg/kg/h), or a combination of phentolamine and propranolol (each 1 mg/kg/h), suggesting a need for new strategies to overcome them.—Carter, J.

Abstract
Objectives To evaluate the short-term 24 h urinary excretion of platinum, arsenic, selenium, magnesium and zinc in patients with lung cancer and with cancer other than lungs treated with cisplatin or/and carboplatin from Antofagasta, Chile. Design Urine measurements of Pt and Se were made by inductively coupled plasma optical emission spectrometry, As by hydride-generation atomic absorption spectrometry and Mg and Zn by means of flame furnace atomic absorption spectrometry. Setting All samples were provided by the Oncological Centre of Antofagasta Regional Hospital (Region of Antofagasta, Chile). Participants Ninety 24-h urine samples from cancer patients after the infusion of Pt-base drugs and 10 24-h urine samples from cancer patients not treated with metal-base drugs. Main outcome measures Concentrations of Pt, Se, As, Zn and Mg coming from 24-h urine samples. Results Pt excreted was not significantly different between patients with lung and other cancers treated with cisplatin. The excretion of Mg, Zn and Se was greater than As. Then, Pt favours the excretion of essential elements. For lung and other types of cancers treated with drugs without Pt, excretion of Mg, Zn and Se was also greater than that of As, suggesting antagonism Mg-Zn-Se–anti-cancer drug relationship. Conclusions The amounts of Mg, Zn and Se excreted were greater than for As either with or without Pt-containing drugs, suggesting antagonist Mg-Zn-Se–anti-cancer drug relationships. The excretion of As, Mg, Zn and Se is induced by Pt. Knowledge obtained can contribute to understanding the arsenic cancer mechanism and the As-Mg-Zn-Se-Pt inter-element association for lung cancer and other types of cancer.

Abstract
The present systematic review summarizes current evidence regarding the mechanisms of action, the efficacy, and the adverse effects of tyrosine kinase inhibitors (TKIs) in ovarian cancer patients. Phase II and III clinical trials were sought in the PubMed database and in the Clinical Trials.gov registry through September 30, 2015. Seventy-five clinical trials regarding TKIs targeting mainly vascular endothelial growth factor receptor, epidermal growth factor receptor, platelet-derived growth factor receptor, and sarcoma tyrosine kinase (Src) were yielded. The most promising results were noted with cediranib, nintedanib, and pazopanib. However, drawing universal conclusions about the potential integration of TKIs in ovarian cancer therapy remains elusive. Furthermore, emerging challenges and directions for the future research are critically discussed.

Abstract
SARI, also called as BATF2, belongs to the BATF family and has been implicated in cancer cell growth inhibition. However, the role and mechanism of SARI in tumour angiogenesis are elusive. Here we demonstrate that SARI deficiency facilitates AOM/DSS-induced colonic tumorigenesis in mice. We show that SARI is a novel inhibitor of colon tumour growth and angiogenesis in mice. Antibody array and HUVEC-related assays indicate that VEGF has an essential role in SARI-controlled inhibition of angiogenesis. Furthermore, Co-IP/PAGE/mass spectrometry indicates that SARI directly targets ceruloplasmin (Cp), and induces protease degradation of Cp, thereby inhibiting the activity of the HIF-1α/VEGF axis. Tissue microarray results indicate that SARI expression inversely correlates with poor clinical outcomes in colon cancer patients. Collectively, our results indicate that SARI is a potential target for therapy by inhibiting angiogenesis through the reduction of VEGF expression and is a prognostic indicator for patients with colon cancer.

Ovarian cancer stem-like cells differentiate into endothelial cells and participate in tumor angiogenesis through autocrine CCL5 signaling. Cancer Lett 2016; 376:137-47.

Abstract
Cancer stem cells (CSCs) are well known for their self-regeneration and tumorigenesis potential. In addition, the multi-differentiation potential of CSCs has become a popular issue and continues to attract increased research attention. Recent studies demonstrated that CSCs are able to differentiate into functional endothelial cells and participate in tumor angiogenesis. In this study, we found that ovarian cancer stem-like cells (CSLCs) activate the NF-κB and STAT3 signal pathways through autocrine CCL5 signaling and mediate their own differentiation into endothelial cells (ECs). Our data demonstrate that CSLCs differentiate into ECs morphologically and functionally. Anti-CCL5 antibodies and CCL5-shRNA lead to markedly inhibit EC differentiation and the tube formation of CSLCs, both in vitro and in vivo. Recombinant human-CCL5 significantly promotes ovarian CSLCs that differentiate into ECs and form microtube network. The CCL5-mediated EC differentiation of CSLCs depends on binding to receptors, such as CCR1, CCR3, and CCR5. The results demonstrated that CCL5-CCR1/CCR3/CCR5 activates the NF-κB and STAT3 signal pathways, subsequently mediating the differentiation of CSLCs into ECs. Therefore, this study was conducted based on the theory that CSCs improve tumor angiogenesis and provides a novel strategy for anti-angiogenesis in ovarian cancer.

Abstract
INTRODUCTION Epithelial ovarian cancer (EOC) is the leading cause of death among gynecologic cancers. The majority of women are diagnosed with advanced stage disease. It is considered a chemosensitive cancer with a high initial response rate to first-line platinum and taxane-based chemotherapy. However, most patients with advanced EOC will relapse with subsequent resistance to conventional chemotherapy and ultimately succumb to their disease. Therefore, new therapeutic agents and strategies are desperately needed to improve the outcomes in patients with advanced EOC. AREAS COVERED This review focuses on the use of Trebananib (a non-VEGF-dependent angiogenesis pathway inhibitor) in EOC. Angiogenesis has been recognized as an important process promoting EOC growth and metastasis. Targeting angiogenesis in EOC have been developed and studied with demonstrated clinical efficacy. Bevacizumab, a humanized monoclonal antibody, that targets vascular endothelial growth factor A (VEGF-A), has been the most well evaluated molecular targeted therapy in the treatment of advanced and recurrent EOC with proven clinical efficacy. However, VEGF-dependent angiogenesis pathway inhibitors are often associated with serious toxicities and drug resistance ultimately develops. Hence, new therapeutic approach targeting the angiopoietin-Tie-2 complex pathway (a non-VEGF-dependent angiogenesis pathway) has gained interest over the past few years as an alternative strategy to overcome VEGF-dependent anti-angiogenesis-related toxicity and resistance. EXPERT OPINION Targeting angiopoietin-Tie-2 pathway represents a promising alternative approach to tumor anti-angiogenesis with a distinct toxicity profile from the VEGF-dependent pathway inhibitors. However, there are still many questions to be answered regarding the optimal treatment schedules, maintenance regimens, duration of maintenance therapy, and the best combination strategy. Currently there is no reliable surrogate molecular, cellular, or genetic marker that would definitively predict response to anti-angiogenic therapy. Identification of certain relevant and predictive biomarkers in the future may optimize treatment's efficacy by distinguishing the subset group of patients with EOC that would derive the most benefit from existing antiangiogenic treatment regimens.

Abstract
OBJECTIVE To assess the antiproliferative, proapoptotic, and antiangiogenic effects of the double-stranded RNA mimic polyinosine-polycytidylic acid (pIC) complexed with polyethylenimine [pIC(PEI)] in xenografted human leiomyomas. DESIGN Heterologous leiomyoma mouse model. SETTING University-affiliated infertility center. ANIMAL(S) Ovariectomized and hormone-replaced nude mice (n = 16) who received human leiomyoma fragment transplantation. INTERVENTION(S) Leiomyoma fragments placed in the peritoneum of 5-week-old nude female mice and treated with the vehicle (n = 8) or 0.6 mg/kg [pIC(PEI)] (n = 8) for 4 weeks. MAIN OUTCOME MEASURE(S) The size of the leiomyoma implants, and cellular proliferation (Ki67), vascularization (PECAM), and apoptosis (OH-ends) assessed by quantitative immunohistochemical/immunofluorescent analysis of the recovered implants. RESULT(S) No significant differences were observed in the size of the leiomyoma implants between groups. Vascularization and proliferation were significantly decreased, and apoptosis was increased in the [pIC(PEI)]-treated group versus control. CONCLUSION(S) We hypothesize that the antiangiogenic and apoptotic effects exerted by [pIC(PEI)] might lead to a decrease in lesion size in this animal model if the compound is administered for longer periods of time. This study provides promising data on [pIC(PEI)] as a potential novel therapeutic agent against human leiomyoma.

Abstract
OBJECTIVE To assess the therapeutic potential of polyinosine-polycytidylic acid, a double-stranded RNA molecule with selective proapoptotic and antiangiogenic activity, complexed with polyethyleneimine (pIC(PEI)) in treating endometriosis. DESIGN A heterologous mouse model of endometriosis was created by injecting human endometrial fragments into the peritoneum. Endometrial fragments were engineered to express the fluorescent protein mCherry as a reporter to monitor status over the course of the 4-week study. SETTING University-affiliated infertility center. ANIMAL(S) Ovariectomized and hormone-replaced nude mice (n = 30) injected with fluorescent-labeled human endometrial fragments at 4-6 weeks of age. INTERVENTION(S) Animals (n = 10 per group) were injected with vehicle (control), the anti-VEGF compound CBO-P11 (0.6 mg/kg), or pIC(PEI) (0.6 mg/kg) twice weekly over the course of 4 weeks. MAIN OUTCOME MEASURE(S) Variations in the size of endometriotic implants were estimated by quantifying the expression of mCherry throughout the course of the experiment. Neovascularization, cellular proliferation, and apoptosis were estimated by quantitative immunofluorescence detection of PECAM, α-SMA, Ki67, and TUNEL. RESULT(S) pIC(PEI) promoted a significant increase in apoptosis and a decrease in neovascularization in human fragments, but did not reduce the size of endometriotic implants. CONCLUSION(S) While pIC(PEI) treatment had significant antiangiogenic and pro-apoptotic effects in this setting, longer periods of exposure than the ones supported by our heterologous model and/or assays in homologous mouse models of endometriosis may be necessary to detect an effect of this compound on lesion size.

Abstract
The humanized monoclonal antibody bevacizumab (Avastin(®)) has been available in the EU since 2005. Results of phase III trials demonstrate that adding intravenous bevacizumab to antineoplastic agents improves progression-free survival and/or overall survival in patients with advanced cancer, including when used as first- or second-line therapy in metastatic colorectal cancer, as first-line therapy in advanced nonsquamous non-small cell lung cancer, as first-line therapy in metastatic renal cell carcinoma, as first-line therapy in metastatic breast cancer, and as first-line therapy in epithelial ovarian, fallopian tube or primary peritoneal cancer or in recurrent, platinum-sensitive or platinum-resistant disease. Results of these studies are supported by the findings of routine oncology practice studies conducted in real-world settings. The tolerability profile of bevacizumab is well defined and adverse events associated with its use (e.g. hypertension, proteinuria, haemorrhage, wound healing complications, arterial thromboembolism, gastrointestinal perforation) are generally manageable. In conclusion, bevacizumab remains an important option for use in patients with advanced cancer.

Abstract
BACKGROUND To examine the angiopoietin pathway inhibitor trebananib IV plus the anti-VEGF agents bevacizumab or motesanib in advanced solid tumours. METHODS In this open-label phase 1b study, patients received IV trebananib 3 mg kg-1 QW plus bevacizumab 15 mg kg-1 Q3W (cohort 1) or motesanib orally 75 mg (cohort 2); or trebananib 10 mg kg-1 plus bevacizumab 15 mg kg-1 (cohort 3) or motesanib 125 mg (cohort 4). If <33% of patients had dose-limiting toxicities (DLTs), dose escalation occurred. Endpoints were treatment-related adverse events (AEs) incidence and pharmacokinetics (primary); anti-trebananib antibodies, biomarkers, and tumour response (secondary). RESULTS Thirty-six patients received ≥ 1 dose of trebananib (cohorts 1, 2, 3, 4; n = 6, 8, 19, 3). DLT of G3 intestinal perforation and G3 tumor haemorrhage occurred in cohorts 2 and 3, respectively (both n = 1). Across both trebananib plus bevacizumab cohorts, the most common AEs included fatigue (n = 8), diarrhoea (n =4), constipation (n = 3), nausea (n = 3), and epistaxis (n = 3). Three patients across those cohorts had grade ≥ 3 AEs. Across the trebananib plus motesanib cohorts, the most common AEs included hypertension (n = 4), diarrhoea (n = 4), nausea (n = 3), fatigue (n = 3), vomiting (n = 2), and decreased appetite (n = 2). Two patients had grade ≥ 3 AEs. Trebananib did not markedly affect motesanib pharmacokinetics. Across the trebananib plus bevacizumab cohorts, two patients had a partial response; 11 patients had stable disease lasting >6 months. Across the trebananib plus motesanib cohorts, one patient had a partial response; five patients had stable disease lasting >6 months. CONCLUSION Trebananib IV 3 mg kg-1 or 10 mg kg-1 plus bevacizumab or motesanib in advanced solid tumours may be associated with less severe toxicities relative to those emerging when combining two anti-VEGF agents.

Abstract
INTRODUCTION A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. PATIENTS AND METHODS Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. RESULTS Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. CONCLUSION Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials.

Abstract
AIM To evaluate the tolerability, pharmacokinetics and tumour response of first-line trebananib plus paclitaxel and carboplatin followed by trebananib maintenance in high-risk or advanced ovarian cancer. METHODS In this open-label phase 1b study, patients received intravenous (IV) trebananib 15 mg/kg administered weekly (QW) plus paclitaxel 175 mg/m(2) once every 3 weeks (Q3W) and carboplatin 6 mg/mL · min Q3W followed by trebananib 15 mg/kg QW monotherapy for 18 months. End-points were dose-limiting toxicities (DLTs; primary); treatment-emergent adverse events (AEs), anti-trebananib antibodies, pharmacokinetics and tumour response (secondary). RESULTS Twenty seven patients (interval debulking surgery [IDS], n=13) were enrolled. No DLTs occurred. During the combination therapy phase, AEs (>50%) in patients with IDS were nausea, diarrhoea, fatigue, decreased appetite and thrombocytopenia. In patients with primary debulking surgery (PDS), they were nausea, diarrhoea, fatigue and localised oedema. Grade 4 AEs were neutropenia (IDS, PDS; all n=3) and thrombocytopenia (IDS, PDS; all n=1). No deaths occurred. Toxicity results pertaining to trebananib maintenance were immature. The treatment combination did not markedly affect the pharmacokinetics across agents. In patients with IDS (n=14 after one patient was reassigned from PDS to IDS), 12 patients had a partial response (PR), two patients had stable disease. In patients with PDS (n=4), three patients had a complete response, one patient had a PR. CONCLUSIONS In women with ovarian cancer receiving IDS or PDS, IV trebananib 15 mg/kg QW plus paclitaxel and carboplatin appears tolerable. Results suggest that the treatment combination followed by trebananib 15 mg/kg monotherapy is associated with antitumour activity.

Abstract
PURPOSE To investigate the mechanisms of regulation and role associated with enhancer of zeste homolog 2 (EZH2) expression in lung cancer cells. EXPERIMENTAL DESIGN We investigated the mechanisms of EZH2 expression associated with the VEGF/VEGFR-2 pathway. Furthermore, we sought to determine the role of EZH2 in response of lung adenocarcinoma to platinum-based chemotherapy, as well as the effect of EZH2 depletion on VEGFR-2-targeted therapy in lung adenocarcinoma cell lines. In addition, we characterized EZH2 expression in lung adenocarcinoma specimens and correlated it with patients' clinical characteristics. RESULTS In this study, we demonstrate that VEGF/VEGFR-2 activation induces expression of EZH2 through the upregulation of E2F3 and hypoxia-inducible factor-1α (HIF1α), and downregulated expression of miR-101. EZH2 depletion by treatment with 3-deazaneplanocin A and knockdown by siRNA decreased the expression of EZH2 and H3K27me3, increased PARP-C level, reduced cell proliferation and migration, and increased sensitivity of the cells to treatment with cisplatin and carboplatin. In addition, high EZH2 expression was associated with poor overall survival in patients who received platinum-based adjuvant therapy, but not in patients who did not receive this therapy. Furthermore, we demonstrated for the first time that the inhibition of EZH2 greatly increased the sensitivity of lung adenocarcinoma cells to the anti-VEGFR-2 drug AZD2171. CONCLUSION Our results suggest that the VEGF/VEGFR-2 pathway plays a role in regulation of EZH2 expression via E2F3, HIF1α, and miR-101. EZH2 depletion decreases the malignant potential of lung adenocarcinoma and sensitivity of the cells to both platinum-based and VEGFR-2-targeted therapy.

Abstract
Epithelial ovarian cancer (EOC) is the most lethal gynecological cancer. Recently, clinical trials have focused on novel antiangiogenic agents in combination with chemotherapy or alone in women with primary and recurrent ovarian cancer. Antiangiogenic agents include monoclonal antibodies, tyrosine-kinase inhibitors, and peptibodies. Many of these agents, including bevacizumab, pazopanib, nintedanib, cediranib, and trebananib, have been evaluated in randomized Phase III clinical trials, and all have demonstrated a progression-free survival (PFS) benefit. Specifically, maintenance pazopanib was shown to improve PFS in women with newly diagnosed EOC. Pazopanib, an oral TKI, inhibits several kinase receptors, including those for vascular endothelial growth factor (-1,-2,-3), platelet-derived growth factor (-α and -β), and fibroblast growth factor. It also targets stem cell-factor receptor (c-kit), interleukin 2-inducible T-cell kinase, lymphocyte-specific protein tyrosine kinase, and colony-stimulating factor 1 receptor. Pazopanib has been investigated in several Phase II and III clinical trials, with results indicating a potential role in the management of EOC. This article provides an overview of pazopanib in the treatment of EOC.

Abstract
Background Angiogenesis is essential for the growth and metastasis of cancer. Although anti-angiogenic agents, particularly vascular endothelial growth factor (VEGF) inhibitors, have exhibited single-agent activity, there is considerable interest in combining these novel drugs with conventional chemotherapy reagents to achieve an optimal clinical efficacy. The objective of this study was to evaluate the benefits of the combination therapy of vascular endothelial growth factor trap (VEGF-Trap) with gemcitabine in a lung tumor model. Methods A luciferase-expressing Lewis lung carcinoma (LLC) model was established in C57BL/6J mice and tumor-bearing mice were randomized into control, VEGF-Trap, gemcitabine and VEGF-Trap/gemcitabine combination groups. Tumor growth and animal survival were monitored. Tumor microvessel density and cell proliferation were evaluated by CD31 and Ki-67 immunohistochemical analysis. TUNEL assay was performed to detect apoptotic cells. The protein levels of Cyclin D1, Pro-Caspase-3, Bcl-2, MMP2 and MMP9 in tumor extracts were examined by western blot. Results VEGF-Trap in combination with gemcitabine showed significantly enhanced inhibition of tumor growth and prolonged mouse survival compared to the VEGF-Trap or gemcitabine monotherapy. The VEGF-Trap/gemcitabine combination therapy not only potently inhibited tumor angiogenesis and cell proliferation, but also increased cellular apoptosis within tumor tissues. In addition, the combination treatment markedly down-regulated the expression of proliferation, anti-apoptosis and invasion related proteins. Conclusion Combination therapy using VEGF-Trap and gemcitabine resulted in improved anti-tumor efficacy in a lung cancer model and VEGF-Trap/gemcitabine combination might represent a promising strategy in the treatment of human lung cancer.

Abstract
Epithelial ovarian cancer is the most lethal gynecologic malignancy; it is highly aggressive and causes almost 125,000 deaths yearly. Despite advances in detection and cytotoxic therapies, a low percentage of patients with advanced stage disease survive 5 y after the initial diagnosis. The high mortality of this disease is mainly caused by resistance to the available therapies. Here, we profiled microRNA (miR) expression in serous epithelial ovarian carcinomas to assess the possibility of a miR signature associated with chemoresistance. We analyzed tumor samples from 198 patients (86 patients as a training set and 112 patients as a validation set) for human miRs. A signature of 23 miRs associated with chemoresistance was generated by array analysis in the training set. Quantitative RT-PCR in the validation set confirmed that three miRs (miR-484, -642, and -217) were able to predict chemoresistance of these tumors. Additional analysis of miR-484 revealed that the sensitive phenotype is caused by a modulation of tumor vasculature through the regulation of the VEGFB and VEGFR2 pathways. We present compelling evidence that three miRs can classify the response to chemotherapy of ovarian cancer patients in a large multicenter cohort and that one of these three miRs is involved in the control of tumor angiogenesis, indicating an option in the treatment of these patients. Our results suggest, in fact, that blockage of VEGF through the use of an anti-VEGFA antibody may not be sufficient to improve survival in ovarian cancer patients unless VEGFB signaling is also blocked.

Abstract
BACKGROUND Bevacizumab is an important agent in the oncologic armamentarium, with activity in a broad spectrum of solid tumors. It has been approved in the management of metastatic colorectal cancer, non-small cell lung cancer, renal cancers, and recurrent glioblastoma multiforme. METHODS We reviewed the published literature and briefing documents of the US Food and Drug Administration that provided the data leading to approval or change in approval status. RESULTS Bevacizumab initially received accelerated approval for the treatment of advanced breast cancer. However, lack of confirmatory data from additional clinical trials resulted in the loss of that indication. Both the expected and unexpected toxicities reported from clinical trials using bevacizumab have helped us to understand the drug's mechanism of action and to identify who are most likely to benefit from this important agent. CONCLUSIONS The side effects of treatment may provide important information about drug mechanism and efficacy. Bevacizumab is clearly an important agent in oncology and is likely to become more significant once a clinical or pathological marker to predict its efficacy has been identified.

Abstract
OBJECTIVES This study sought to examine the effects and underlying mechanisms of systemic VEGF inhibition in experimental atherosclerosis and aortic endothelial cells. BACKGROUND Pharmacological inhibition of vascular endothelial growth factor (VEGF), a major mediator of angiogenesis, has become a widely applied treatment of certain cancers and multiple ocular diseases including age-related macular degeneration. However, recent clinical trials raise concern for systemic vascular adverse effects, prompting the Food and Drug Administration to revoke the approval of bevacizumab for metastatic breast cancer. METHODS Eight-week old apolipoprotein E knockout mice received a high-cholesterol diet (1.25% cholesterol) for 24 weeks and were exposed to a systemic pan-VEGF receptor inhibitor (PTK787/ZK222584, 50mg/kg/d) or placebo (gavage) for the last 10 weeks. Atherosclerotic lesions were characterized in thoraco-abdominal aortae and aortic arches. Mechanistic analyses were performed in cultured human aortic endothelial cells. RESULTS Systemic VEGF inhibition increased atherosclerotic lesions by 33% whereas features of plaque vulnerability (i.e. necrotic core size, fibrous cap thickness) remained unchanged compared with controls. Aortic eNOS expression was decreased (trend). In human endothelial cells VEGF inhibition induced a dose-dependent increase in mitochondrial superoxide generation with an uncoupling of eNOS, resulting in reduced NO availability and decreased proliferation. CONCLUSION Systemic VEGF inhibition disrupts endothelial homeostasis and accelerates atherogenesis, suggesting that these events contribute to the clinical cardiovascular adverse events of VEGF-inhibiting therapies. Cardiovascular safety profiles of currently applied anti-angiogenic regimens should be determined to improve patient selection for therapy and allow close monitoring of patients at increased cardiovascular risk.

Abstract
OBJECTIVE To determine response rates (RR), progression-free survival (PFS), overall survival (OS), and toxicity in patients treated with cytotoxic chemotherapy, in combination with bevacizumab compared to cytotoxic chemotherapy alone, in the setting of recurrent ovarian cancer. MATERIALS AND METHODS After obtaining Institutional Review Board approval, two cohorts of patients with recurrent ovarian cancer were identified: 1) patients that received cytotoxic chemotherapy with bevacizumab from January 2006 to June 2009; 2) patients that received cytotoxic chemotherapy alone. RR were measured using RECIST criteria or by CA-125 levels using modified Rustin criteria. RR, OS, and PFS were determined using Kaplan-Meier survival analysis. RESULTS Thirty-two patients that received bevacizumab in combination with cytotoxic chemotherapy and 32 patients that received cytotoxic chemotherapy alone were identified. The control patients were matched for age, platinum response, histology, surgical outcome, grade, and number of previous chemotherapy regimens. There were no differences between the two cohorts in the rates of venous thromboembolism (VTE) (p = 0.39), bleeding (p = 0.15) or bowel obstruction (p = 0.40). The rate of hypertension in the bevacizumab cohort was greater than in the comparison cohort (p < 0.005). There were no differences in response rates PR/CR vs SD/PD (p = 0.46), OS (p = 0.79) or PFS (p = 0.43). CONCLUSIONS With increased toxicity, increased cost of therapy and no improvement in PFS or OS, the role of bevacizumab in patients with recurrent ovarian cancer warrants further investigation.

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
BACKGROUND Arsenic exposure increases the risk of non-cancerous and cancerous diseases. In the Antofagasta region in Chile, an established relationship exists between arsenic exposure and the risk of cancer of the bladder, lung and skin. Platinum-based drugs are first-line treatments, and many works recognise selenium as a cancer-fighting nutrient. We characterised the short-term urinary excretion amounts of arsenic, selenium and platinum in 24-h urine samples from patients with lung cancer and those with cancer other than lung treated with cisplatin or/and carboplatin. As - Se - Pt inter-element relationships were also investigated. RESULTS The amounts of platinum excreted in urine were not significantly different between patients with lung cancer and those with other cancers treated with cisplatin, despite the significant variation in platinum amounts supplied from platinum-based drugs. In general, the analytical amounts of excreted selenium were greater than those for arsenic, which could imply that platinum favours the excretion of selenium. For other types of cancers treated with drugs without platinum, excretion of selenium was also greater than that of arsenic, suggesting an antagonist selenium-anti-cancer drug relationship. CONCLUSIONS Regards the baseline status of patients, the analytical amounts of excreted Se is greater than those for As, particularly, for cisplatin chemotherapy. This finding could imply that for over the As displacement Pt favours the excretion of Se. The analytical amounts of excreted Se were greater than those for As, either with and without Pt-containing drugs, suggesting an antagonist Se-anti-cancer drug relationship. However, it seemed that differences existed between As - Se - Pt inter-element associations in patients treated for lung cancer in comparison with those treated for cancer other than lung. Therefore, knowledge obtained in this work, can contribute to understanding the arsenic cancer mechanism and the As - Se - Pt inter-element association for lung cancer and other types of cancer, which in some cases respond at a linear mathematical model.
