Levit SL, Tang C. Polymeric Nanoparticle Delivery of Combination Therapy with Synergistic Effects in Ovarian Cancer. NANOMATERIALS (BASEL, SWITZERLAND) 2021; 11:1048. [PMID: 33923947 PMCID: PMC8072532 DOI: 10.3390/nano11041048] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 04/10/2021] [Accepted: 04/12/2021] [Indexed: 12/23/2022]
Abstract
Treatment of ovarian cancer is challenging due to late stage diagnosis, acquired drug resistance mechanisms, and systemic toxicity of chemotherapeutic agents. Combination chemotherapy has the potential to enhance treatment efficacy by activation of multiple downstream pathways to overcome drug resistance and reducing required dosages. Sequence of delivery and the dosing schedule can further enhance treatment efficacy. Formulation of drug combinations into nanoparticles can further enhance treatment efficacy. Due to their versatility, polymer-based nanoparticles are an especially promising tool for clinical translation of combination therapies with tunable dosing schedules. We review polymer nanoparticle (e.g., micelles, dendrimers, and lipid nanoparticles) carriers of drug combinations formulated to treat ovarian cancer. In particular, the focus on this review is combinations of platinum and taxane agents (commonly used first line treatments for ovarian cancer) combined with other small molecule therapeutic agents. In vitro and in vivo drug potency are discussed with a focus on quantifiable synergistic effects. The effect of drug sequence and dosing schedule is examined. Computational approaches as a tool to predict synergistic drug combinations and dosing schedules as a tool for future nanoparticle design are also briefly discussed.

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

Abstract
As cancer growth and development typically involves multiple genes and pathways, combination therapy has been touted as the standard of care in the treatment of cancer. However, drug toxicity becomes a major concern whenever a patient takes 2 or more drugs simultaneously at the maximum tolerable dosage. A potential solution would be administering the drugs in a sequential or alternating manner rather than concurrently. This study therefore examines the feasibility of such an approach from a switched system control perspective. Particularly, we study how genetic regulatory systems respond to sequential (switched) drug inputs using the time-based switching mechanism. The design of the time-driven drug switching function guarantees the stability of the genetic regulatory system and the repression of the diseased genes. Simulation results using proof-of-concept models and the proliferation and survival pathways with sequential drug inputs show the effectiveness of the proposed approach.

Abstract
Background Treatment outcomes appear to be better for ovarian cancer (OC) patients carrying the BRCA1/2 germline mutation than for patients with sporadic OC. However, most published data are for North American, British and Jewish populations. There have been very few studies on treatment outcomes in Central and Eastern European patients with OC. The aim of this study was to analyse prognostic factors in Polish patients with BRCA1-dependent OC (BRCA1-OC). Methods The records of patients with OC treated with surgery and chemotherapy at the Centre of Oncology in Kraków, Poland, between 2004 and 2009 were reviewed. Based on family history, a group of 249 consecutive patients fulfilling the criteria for risk of hereditary OC were selected and tested for the germline BRCA1 mutation. Response to combination therapy (surgery and chemotherapy) in the BRCA1-OC group was assessed based on clinical examination, imaging and serum CA125. Results Germline BRCA1 mutations were detected in 69 of the 249 patients, but three of these patients failed to complete the study. Finally, 66 patients with BRCA1-OC were included in the study group. The median age of the study patients was 49.5 years. All had undergone primary or interval cytoreductive surgery and chemotherapy. Progression occurred in 48 (72.7 %) of the 66 patients and median time to progression was 20 months. The 5-year overall survival rate in was 43.9 % and median survival time was 32.3 months. On multivariate analysis, the endometrial subtype of OC and serum CA125 < 12.5 U/ml at the end of treatment were independent, positive prognostic factors for 5-year overall survival. Conclusion Prognostic factors for favourable treatment outcomes in Polish patients with BRCA1-OC do not appear to differ from those in patients with sporadic OC. The incidence of the endometrial subtype of OC was relatively high (34.9 %) among women in the study. This was unexpected and has not been reported previously. This subtype of OC was an independent prognostic factor for favourable treatment outcomes.

Abstract
OBJECTIVE To evaluate whether the addition of topotecan can improve the efficacy of carboplatin and paclitaxel in first-line treatment of advanced epithelial ovarian cancer. METHODS Meta-analysis was performed using a random effects model. RESULTS Four randomized controlled trials with a total of 3632 patients were identified and included in the meta-analysis. No significant differences were observed in terms of progression-free survival (P=0.400), overall survival (P=0.502) and overall response rate (P=0.953) between patients treated with topotecan plus carboplatin and paclitaxel versus carboplatin and paclitaxel. However, there were significantly higher rates of grade 3-4 leucopenia (P=0.024), neutropenia (P<0.001), anaemia (P<0.001), and thrombopenia (P<0.001) in the topotecan plus carboplatin and paclitaxel group. No significant differences were observed in grade 3-4 nausea (P=0.352) and vomiting (P=0.092) between these two groups. CONCLUSION Topotecan plus carboplatin and paclitaxel did not improve survival outcomes and caused more haematological toxicity for advanced ovarian cancer.

Abstract
OBJECT Treatment options for anaplastic or malignant intramedullary spinal cord tumors (IMSCTs) remain limited. Paclitaxel has potent cytotoxicity against experimental intracranial gliomas and could be beneficial in the treatment of IMSCTs, but poor CNS penetration and significant toxicity limit its use. Such limitations could be overcome with local intratumoral delivery. Paclitaxel has been previously incorporated into a biodegradable gel depot delivery system (OncoGel) and in this study the authors evaluated the safety of intramedullary injections of OncoGel in rats and its efficacy against an intramedullary rat gliosarcoma. METHODS Safety of intramedullary OncoGel was tested in 12 Fischer-344 rats using OncoGel concentrations of 1.5 and 6.0 mg/ml (5 μl); median survival and functional motor scores (Basso-Beattie-Bresnahan [BBB] scale) were compared with those obtained with placebo (ReGel) and medium-only injections. Efficacy of OncoGel was tested in 61 Fischer-344 rats implanted with an intramedullary injection of 9L gliosarcoma containing 100,000 cells in 5 μl of medium, and randomized to receive OncoGel administered on the same day (in 32 rats) or 5 days after tumor implantation (in 29 rats) using either 1.5 mg/ml or 3.0 mg/ml doses of paclitaxel. Median survival and BBB scores were compared with those of ReGel-treated and tumor-only rats. Animals were killed after the onset of deficits for histopathological analysis. RESULTS OncoGel was safe for intramedullary injection in rats in doses up to 5 μl of 3.0 mg/ml of paclitaxel; a dose of 5 μl of 6.0 mg/ml caused rapid deterioration in BBB scores. OncoGel at concentrations of 1.5 mg/ml and 3.0 mg/ml paclitaxel given on both Day 0 and Day 5 prolonged median survival and preserved BBB scores compared with controls. OncoGel 1.5 mg/ml produced 62.5% long-term survivors when delivered on Day 0. A comparison between the 1.5 mg/ml and the 3.0 mg/ml doses showed higher median survival with the 1.5 mg/ml dose on Day 0, and no differences in median survival or BBB scores after treatment on Day 5. CONCLUSIONS OncoGel is safe for intramedullary injection in rats in doses up to 5 μl of 3.0 mg/ml, prolongs median survival, and increases functional motor scores in rats challenged with an intramedullary gliosarcoma at the doses tested. This study suggests that locally delivered chemotherapeutic agents could be of temporary benefit in the treatment of malignant IMSCTs under experimental settings.

Abstract
Chemotherapy-induced neutropenia is a major risk factor for infection-related morbidity and mortality and also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact the success of treatment, particularly when treatment intent is either curative or to prolong survival. In Europe, prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim (including approved biosimilars), lenograstim or pegfilgrastim is available to reduce the risk of chemotherapy-induced neutropenia. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. The need for generally applicable, European-focused guidelines led to the formation of a European Guidelines Working Party by the European Organisation for Research and Treatment of Cancer (EORTC) and the publication in 2006 of guidelines for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. A new systematic literature review has been undertaken to ensure that recommendations are current and provide guidance on clinical practice in Europe. We recommend that patient-related adverse risk factors, such as elderly age (≥65 years) and neutrophil count be evaluated in the overall assessment of FN risk before administering each cycle of chemotherapy. It is important that after a previous episode of FN, patients receive prophylactic administration of G-CSF in subsequent cycles. We provide an expanded list of common chemotherapy regimens considered to have a high (≥20%) or intermediate (10-20%) risk of FN. Prophylactic G-CSF continues to be recommended in patients receiving a chemotherapy regimen with high risk of FN. When using a chemotherapy regimen associated with FN in 10-20% of patients, particular attention should be given to patient-related risk factors that may increase the overall risk of FN. In situations where dose-dense or dose-intense chemotherapy strategies have survival benefits, prophylactic G-CSF support is recommended. Similarly, if reductions in chemotherapy dose intensity or density are known to be associated with a poor prognosis, primary G-CSF prophylaxis may be used to maintain chemotherapy. Clinical evidence shows that filgrastim, lenograstim and pegfilgrastim have clinical efficacy and we recommend the use of any of these agents to prevent FN and FN-related complications where indicated. Filgrastim biosimilars are also approved for use in Europe. While other forms of G-CSF, including biosimilars, are administered by a course of daily injections, pegfilgrastim allows once-per-cycle administration. Choice of formulation remains a matter for individual clinical judgement. Evidence from multiple low level studies derived from audit data and clinical practice suggests that some patients receive suboptimal daily G-CSFs; the use of pegfilgrastim may avoid this problem.

Abstract
The aim of this retrospective analysis was to investigate the efficacy and adverse effects of the monoclonal antivascular endothelial growth factor antibody bevacizumab (Avastin(R)) combined with chemotherapeutic agents in non-protocol patients with recurrent ovarian, fallopian tube, or primary peritoneal malignancies. Using our databases, we identified patients treated with bevacizumab combination therapy since June 2005. Responses were evaluated with Response evaluation Criteria in Solid tumors and serum CA125 Rustin criteria. Toxicity was assessed according to the Common toxicity Criteria (CTC) v.3.0. Data from 64 patients were included. The median patient age was 58 years, and they had undergone a median of 4.5 (range, 1-10) prior cytotoxic chemotherapy regimens. The median length of follow-up was 8 months (range, 2-29). The most commonly used combinations were bevacizumab plus taxanes (26.6%) and plus cyclophosphamide (26.6%). A median of 4 cycles of therapy with a median bevacizumab dose of 3,600 mg (range, 500-18,240) were administered. An overall response rate of 21.3% was observed in 13 patients with partial response, and another 42.6% of patients had stable disease. Among the patients with elevated pretreatment serum CA125 concentration, an overall response rate of 46.3% (25/54) was observed according to modification of the Rustin criteria. Fifteen (23.4%) patients had grades 3 or 4 adverse events. Gastrointestinal perforations occurred in 2 (3.1%) patients. Seventeen (26.6%) patients had improved performance status scores. Bevacizumab combined with chemotherapy showed promising clinical benefits, with significant response of serum CA125 concentration and moderate adverse effects.

Abstract
BACKGROUND Ovarian cancer is the fourth cause of death from gynaecological cancer and cervical cancer is the first in women <45 years old in developing countries. The aim of this article is to review the role of topotecan (Hycamtin), a semi-synthetic alkaloid derivative of camptothecin, in ovarian and cervical cancer in monotherapy and in combination. METHODS This article reviews the mechanism of action, pharmacokinetics, toxicity and efficacy of topotecan. The paper also reports the principal phases II and III studies of topotecan in advanced or recurrent ovarian and cervical cancer. RESULTS Topotecan (Hycamtin), currently indicated for the treatment of relapsed ovarian cancer, has demonstrated activity both in platinum-sensitive and in platinum-resistant disease. The combination cisplatin-topotecan for the treatment of advanced and recurrent cervical cancer has demonstrated a clinical benefit in terms of response rate, overall survival and progression free survival. Haematological toxicity of topotecan also is easy to manage and not cumulative, especially with the weekly scheduled recently introduced in clinical practice. CONCLUSION Topotecan (Hycamtin) will continue to play a role in the treatment of advanced ovarian and cervical cancer, in monotherapy or in combination with other cytotoxic agents.

Abstract
While bevacizumab has shown activity in recurrent ovarian cancer, a higher than expected incidence of bowel perforations has been reported in recent trials. We sought to determine factors associated with toxicity and tumor response in patients with relapsed ovarian cancer treated with bevacizumab. A retrospective review of patients with recurrent ovarian cancer treated with bevacizumab was undertaken. Response was determined radiographically and through CA125 measurements. Statistical analysis to determine factors associated with toxicity and response was performed. Sixty-two eligible patients were identified. The cohort had received a median of 5 prior chemotherapy regimens. Single-agent bevacizumab was administered to 12 (19%), while 50 (81%) received the drug in combination with a cytotoxic agent. Grade 3–5 toxicities occurred in 15 (24%) patients, including grade 3–4 hypertension in 4 (7%), gastrointestinal perforations in 7%, and chylous ascites in 5%. Development of chylous ascites and gastrointestinal perforations appeared to correlate with tumor response. The overall response rate was 36% (4 complete response, 17 partial response), with stable disease in 40%. A higher objective response rate was seen in the bevacizumab combination group compared to single-agent treatment (43% vs 10%) (P = 0.07). However, 29 grade 3–5 toxic episodes were seen in the combination group vs only 1 in the single-agent bevacizumab cohort (P = 0.071). We conclude that bevacizumab demonstrates promising activity in recurrent ovarian cancer. The addition of a cytotoxic agent to bevacizumab improved response rates at the cost of increased toxicity. Gastrointestinal perforations occurred in 7%. The perforations occurred in heavily pretreated patients who were responding to therapy

Abstract
BACKGROUND Chemotherapeutic agents such as topotecan can be used to treat ovarian cancer. The effects of using topotecan as a therapeutic agent have not been previously been systematically reviewed. OBJECTIVES To systematically evaluate the effectiveness and safety of topotecan for the treatment of ovarian cancer. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL), (Issue 4, 2006); Cochrane Gynaecological Cancer Review Group (CGCRG) Specialised Register (Cochrane Library Issue 4, 2006); MEDLINE (January 1990 to 27 July 2006); EMBASE (January 1990 to 27 July 2006); The European Organization for the Research and Treatment of Cancer (EORTC) database (to 1 August 2006); CBM (Chinese Biomedical Database) (January 1990 to 27 July 2006). SELECTION CRITERIA Randomised controlled trials (RCTs) which randomized patients with ovarian cancer to single or combined use of topotecan versus interventions without topotecan, or different remedies of topotecan. DATA COLLECTION AND ANALYSIS Two review authors independently extracted and analysed data. MAIN RESULTS Six studies including 1323 participants were eligible for this review (Gordon 2004a; Gore 2001a; Gore 2002; Hoskins 1998; Huinink 2004; Placido 2004) All studies, as reported, were identified as being of poor methodological quality. Topotecan had comparable effectiveness to prolong progression-free survival (PFS) compared with pegylated liposomal doxorubicin (PLD), (16.1 weeks versus 17.0 weeks; p = 0.095). Overall survival (OS) time was similar in participants using PLD compared with topotecan (56.7 weeks versus 60 weeks; p = 0.341). Topotecan was more hematologically toxic compared with paclitaxel or PLD, relative risks (RRs) of hematological events: ranged from 1.03 to 14.46 and 1.73 to 27.12 respectively. A 21-day cycle of topotecan was more toxic than a 42-day cycle (RRs of hematological and non-hematological events ranged from 1.03 to 8). Intravenous and oral topotecan had comparable toxicity. Topotecan delayed progression more effectively compared with paclitaxel (23.1 weeks versus 14 weeks, p = 0.0021). Participants were more likely to respond to topotecan on a 21-day cycle as opposed to a 42-day cycle (RR 7.23, 95% CI 0.94 to 55.36). Small tumor diameter, sensitivity to platinum-based chemotherapy was associated with better prognosis. Small sample size, methodological flaws and poor reporting of the included trials made measurement bias of the trials difficult to assess. AUTHORS' CONCLUSIONS Topotecan appears to have a similar level of effectiveness as paclitaxel and PLD, though with different patterns of side effects. Larger, well-designed RCTs are required in order to define an optimal regime.

Abstract
BACKGROUND The study was undertaken to determine the safety and efficacy of the monoclonal, antivascular endothelial growth factor antibody bevacizumab in combination with cytotoxic chemotherapy for women with platinum-refractory ovarian cancer. METHODS A retrospective analysis of women who received bevacizumab in combination with a cytotoxic agent was performed. Response was determined by measurable disease or assessment of serial cancer antigen (CA) 125 measurements. RESULTS Twenty-three patients were identified. The patients were heavily pretreated with a median of 7 prior regimens including a median of 3 prior platinum regimens. The combination regimen included cyclophosphamide in 15 (65%), 5-fluorouracil (5-FU) in 6 (26%), docetaxel in 1 (4%), and gemcitibine/liposomal doxorubicin in 1 (4%). Two (9%) women developed chylous ascites during treatment. CTC Grade 4-5 toxicities occurred in 4 (17%) subjects. Gastrointestinal perforation occurred in 2 (9%) patients. Measurable disease was present in 22. The overall best response rate was 35% and all 8 were partial responses (PRs). Stable disease was found in a further 10 (44%) women, whereas progressive disease was observed in 5 (22%). The median time to progression was 5.6 months in patients with a PR and 2.3 months in subjects with stable disease. Three (13%) women experienced a progression-free interval (PFI) of >6 months. At last follow-up, 8 (35%) subjects had died of disease, whereas 15 (65%) women were alive with disease. CONCLUSIONS Combination bevacizumab therapy demonstrated activity in heavily pretreated women with ovarian cancer. Gastrointestinal perforations were identified in 9%. Despite the toxicity of the regimen, prospective studies, particularly in less heavily pretreated patients, are warranted.

Eur J Cancer 2006; 42:2433-53.

Abstract
Chemotherapy-induced neutropenia is not only a major risk factor for infection-related morbidity and mortality, but is also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact on the success of treatment, particularly when treatment intent is either curative or to prolong survival. The incidence of severe or FN can be reduced by prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim, lenograstim or pegfilgrastim. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. While several academic groups have produced evidence-based clinical practice guidelines in an effort to standardise and optimise the management of FN, there remains a need for generally applicable, European-focused guidelines. To this end, we undertook a systematic literature review and formulated recommendations for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. We recommend that patient-related adverse risk factors such as elderly age (>or=65 years), be evaluated in the overall assessment of FN risk prior to administering each cycle of chemotherapy. In addition, when using a chemotherapy regimen associated with FN in >20% patients, prophylactic G-CSF is recommended. When using a chemotherapy regimen associated with FN in 10-20% patients, particular attention should be given to patient-related risk factors that may increase the overall risk of FN. In situations where dose-dense or dose-intense chemotherapy strategies have survival benefits, prophylactic G-CSF support is recommended. Similarly, if reductions in chemotherapy dose intensity or density are known to be associated with a poor prognosis, primary G-CSF prophylaxis may be used to maintain chemotherapy. Finally, studies have shown that filgrastim, lenograstim and pegfilgrastim have clinical efficacy and we recommend the use of any of these agents to prevent FN and FN-related complications, where indicated.

Abstract
The feasibility of sequential carboplatin followed by docetaxel-based therapy for untreated ovarian cancer was determined. Patients received four q3w cycles of carboplatin AUC 7, then four q3w cycles of either docetaxel 100 mg m(-2) (day 1) (arm A); docetaxel 75 mg m(-2) (day 8) and gemcitabine 1250 mg m(-2) (days 1,8) (arm B) or docetaxel 25 mg m(-2) and gemcitabine 800 mg m(-2) (both given weekly (days 1,8,15)) (arm C). A total of 44 patients were randomised to each treatment arm. None of the arms demonstrated an eight cycle completion rate (70.5/72.7/45.5% in arms A/B/C, respectively), which was statistically greater than 60% (P=0.102, P=0.056, P=0.982) which was our formal feasibility criteria, although only the completion rate in arm C was clearly worse than this level. The overall response rate (ORR) after carboplatin was 65.7% in 70 evaluable patients. In evaluable patients, ORRs after docetaxel-based cycles were: arm A 84.0% (21 out of 25); arm B 77.3% (17 out of 22); arm C 69.6% (16 out of 23). At follow-up (median 30 months), median progression-free survival times were: arm A 15.5 months (95% CI: 10.5-20.6); arm B 18.1 months (95% CI: 15.9-20.3); arm C, 13.7 months (95% CI: 12.8-14.6). Neutropenia was the predominant grade 3-4 haematological toxicity: 77.8/85.7/54.4% in arms A/B/C, respectively. Dyspnoea was markedly increased in both gemcitabine-containing arms (P=0.001) but was worse in arm C. Although just failing to rule out eight cycle completion rates less than 60%, within the statistical limitations of these small cohorts, the overall results for arms A and B are encouraging. Larger phase III studies are required to test these combinations.

Abstract
The feasibility of combination irinotecan, carboplatin and docetaxel chemotherapy as first-line treatment for advanced epithelial ovarian carcinoma was assessed. One hundred patients were randomised to receive four 3-weekly cycles of carboplatin (area under the curve (AUC) 7) followed by four 3-weekly cycles of docetaxel 100 mg m(-2) (arm A, n=51) or docetaxel 60 mg m(-2) with irinotecan 200 mg m(-2) (arm B, n=49). Neither arm met the formal feasibility criterion of an eight-cycle treatment completion rate that was statistically greater than 60% (arm A 71% (90% confidence interval (CI) 58-81%; P=0.079; arm B 67% (90% CI 55-78%; P=0.184)). Median-dose intensities were >85% of planned dose for all agents. In arms A and B, 15.6 and 12.2% of patients, respectively, withdrew owing to treatment-related toxicity. Grade 3-4 sensory neurotoxicity was more common in arm A (1.9 vs 0%) and grade 3-4 diarrhoea was more common in arm B (0.6 vs 3.5%). Of patients with radiologically evaluable disease at baseline, 50 and 48% responded to therapy in arms A and B, respectively; at median 17.1 months' follow-up, median progression-free survival was 17.1 and 15.9 months, respectively. Although both arms just failed to meet the formal statistical feasibility criteria, the observed completion rates of around 70% were reasonable. The addition of irinotecan to first-line carboplatin and docetaxel chemotherapy was generally well tolerated although associated with increased gastrointestinal toxicity. Further exploratory studies of topoisomerase-I inhibitors in this setting may be warranted.

Abstract
Single-agent gemcitabine demonstrated response rates of 11-60% in platinum/paclitaxel-resistant ovarian cancer. Twenty-four patients with epithelial ovarian cancer were treated with gemcitabine 800 mg/m2 on days 1 and 8, carboplatin area under the curve 5 on day 1, and paclitaxel 175 mg/m2 over 3 h on day 1 every 3 weeks for six cycles. Median age was 54 years, and FIGO stage distribution was IIC, 1 patient, III, 18, and IV, 5. A total of 22 (92%) patients completed all the six planned courses of chemotherapy. Doses were reduced in 8 out of 24 (33%) patients. Of the 17 patients with measurable disease, 15 underwent an interval debulking surgery. Prior to interval debulking surgery, all 15 patients had a partial response according to the response evaluation criteria in solid tumors criteria. Overall in the 17 patients with measurable disease, the response rate at the end of the first-line chemotherapy (including interval debulking) was 94% (14 [82%] complete response and 2 [12%], partial response). One patient (6%) received only one cycle due to early progression. Using the CA125 criteria as defined by the Gynecologic Cancer Intergroup, all patients had at least a partial response prior to interval debulking, and the overall response rate of the whole first-line chemotherapy and interval debulking (n= 15) was observed in 21 out of 23 patients (91%). The dose-limiting toxicity was bone marrow toxicity. Median overall survival was 28 months, and the 2-year actuarial survival was 73%. The gemcitabine, carboplatin, paclitaxel triplet has an acceptable toxicity with high response rates as first-line therapy in advanced ovarian cancer.

Abstract
INTRODUCTION Paclitaxel, a microtubule binding agent with potent anti-glioma activity in vitro, exhibits poor penetrance to the CNS when delivered systemically. To minimize toxicity and reach therapeutic concentrations in the CNS, paclitaxel was previously incorporated into biodegradable microspheres (Paclimer), and the efficacy of Paclimer was determined in a rat model of malignant glioma. In this study we report the safety of intracranial Paclimer in a canine dose escalation toxicity study to prepare its translation into clinical scenarios. METHODS Twelve normal beagle dogs underwent a right parieto-occipital craniectomy and were randomized to receive either Paclimer at 2-mg/kg (n=5), empty microspheres at 2-mg/kg (n=1), Paclimer at 20-mg/kg (n=5), or empty microspheres at 20-mg/kg (n=1). Post-operatively, dogs were observed daily for signs of neurotoxicity. Complete blood counts and plasma levels of paclitaxel were obtained weekly. CSF levels and MRI scans were obtained on days 14-120. Paclitaxel concentrations were quantified by LC-MS. RESULTS Animals treated with 20-mg/kg Paclimer had minimal paclitaxel levels in plasma (range 0-7.84 ng/ml) and CSF (range 0-1.16 ng/ml). Animals treated with 2 mg/kg Paclimer had undetectable levels of paclitaxel in plasma, CSF was not obtained to minimize animal suffering. All animals exhibited normal behavior and weight gain, and were alive post-operatively through the last day of the study (day 60-120) without signs of neurological toxicity. There was no evidence of systemic toxicity or myelosuppression. MR imaging was comparable between Paclimer animals and controls. Adverse effects included wound infections and a brain abscess, all of which responded to antibiotic therapy, and one ventriculomegaly due to communicating hydrocephalus. CONCLUSIONS Paclimer-based delivery of paclitaxel is safe for intraparenchymal delivery at the tested doses in normal dogs.

Abstract
Epithelial ovarian cancer is the most lethal gynaecological cancer among women worldwide, with 6000 new cases diagnosed in the UK each year. Most women present with advanced disease, but, despite a good initial response to treatment, most relapse. The overall 5-year survival rate is 46%, although this drops to about 13% in women with advanced disease. Transvaginal ultrasound and the tumour marker CA125 are being investigated for screening in ongoing randomised trials. Treatment of ovarian cancer is dependent on clinical stage, and should always be managed within a multidisciplinary team. Most cases will require a pelvic clearance and adjuvant chemotherapy. Current guidelines by the National Institute of Clinical Excellence (NICE) recommend that first-line chemotherapy should include a platinum-based regimen with or without paclitaxel. Relapsed ovarian cancer is incurable; however, chemotherapy can improve quality of life and survival. Gene therapy, immunotherapy and signal transduction inhibitors are all potential future therapies, and are being investigated in ongoing clinical research. In this paper we review the literature on the epidemiology, pathology, clinical features and the current treatment options in epithelial ovarian cancer.
