Abstract
OBJECTIVE Recurrent platinum-resistant ovarian cancer has a poor prognosis with limited therapeutic options. Sub-therapeutic intra-tumoral drug concentrations may add to therapy resistance. CPC634 (docetaxel entrapped in CriPec nanoparticles) was designed to enhance tumor accumulation of drug with localized drug release at the target site to increase therapeutic efficacy. This study investigated the therapeutic effect of CPC634 in patients with platinum-resistant ovarian cancer. METHODS According to a Simon 2-stage design trial, the first stage included 13 patients, and 12 patients were enrolled in the second stage. Eligible patients had measurable disease and had progressed ≤6 months after the last platinum-based therapy. Platinum-refractory disease was excluded. In stage 1, the number of previous treatment lines was unlimited; in the second stage, a maximum of two prior lines altogether were allowed. The primary endpoint was the objective response rate by Response Evaluation Criteria in Solid Tumor (RECIST) V1.1. Secondary endpoints included safety, progression-free survival at 6 months, cancer antigen 125 (CA125) response, and disease control rate. RESULTS The patients' median age was 66 years (range 22-77) and most were International Federation of Gynecology and Obstetrics (FIGO) stage III (56%). The median number of previous treatment lines was 3 (range 3-5) in stage I and 2 (range 1-4) in stage II of the study. None of the patients had an objective response, one patient had a CA125 response (5%), and seven patients had stable disease at first evaluation (35%). Median progression-free survival was 1.4 months in stage 1 and 3.0 months in stage 2. Adverse events (all grades) were mainly gastrointestinal in 24 patients (96%), fatigue in 11 (44%), dyspnea in 10 (40%), and infections in 10 (40%) of patients. Grade 3 or higher adverse events occurred in 14 patients (36%), including gastrointestinal in 4 (16%), anemia in 3 (12%), and febrile neutropenia, fatigue, chronic kidney disease, dehydration, and hypertension each in 1 (4%) patient. The trial was stopped prematurely due to futility. CONCLUSIONS Treatment with CPC634 was feasible, but without apparent clinical activity in patients with recurrent platinum-resistant ovarian cancer. Side effects were mainly gastrointestinal in 24 (96%) patients, including nausea, vomiting, and decreased appetite, fatigue, anemia, and dyspnea.

Abstract
Treatment approaches for relapsed ovarian cancer have evolved over the past decade from a calendar-based decision tree to a patient-oriented biologically driven algorithm. Nowadays, platinum-based chemotherapy should be offered to all patients with a reasonable chance of responding to this therapy. The treatment-free interval for platinum is only one of many factors affecting patients' eligibility for platinum re-treatment. Bevacizumab increases the response to chemotherapy irrespective of the cytotoxic regimen and can be valuable in patients with an urgent need for symptom relief (e.g. pleural effusion, ascites). For patients with recurrent high-grade ovarian cancer, which responds to platinum-based treatment, maintenance therapy with a poly(ADP-ribose) polymerase inhibitor can be offered, regardless of the BRCA mutation status. Here we review contemporary decision-making processes in the systemic treatment of relapsed ovarian cancer.

Abstract
Objective This study investigated pre- and post-treatment tumor and lymph node dimension response rates and differences between side-effect profiles in patients with locally advanced inoperable nonsmall-cell lung cancer (NSCLC) receiving radiotherapy (RT) and concurrent chemotherapy (CT). Materials and Methods A total of 30 inoperable patients who had not previously received RT and having a mean age of 58.73±8.65 years with sufficient hematological reserves and normal hepatic and renal functions were included in the study. Those with pleural effusion, supraventricular lymph node metastasis, and N3 lymph node involvement were excluded. Group I (n=15) received a 21-day 75 mg/m2 cisplatin (D1) and 15 mg/m2 vinorelbine (D1, D8), whereas Group II (n=15) received 45 mg/m2 paclitaxel and AUC2 carboplatin weekly. RT was administered using a linear accelerator device with the 3D conformal RT technique at 6-18 MV energy with a 1.8-2 Gy fraction for 6-7 weeks. Results Patients were randomized into Group I receiving RT and concurrent cisplatin-vinorelbine and Group II receiving weekly paclitaxel-carboplatin CT. Pre- and post-treatment tumor and lymph node dimensions significantly differed in both groups (p<0.001 and p<0.01, respectively). No significant change was observed in post-RT tumor and lymph node dimensions in terms of applied CT regimens (p>0.05). Conclusion The significant response achieved with concurrent RT and CT in groups I and II in the local advanced stage of NSCLC is important for local tumor control. Responses to treatment in the group of two arms did not differ.

Switching from standard to dose-dense chemotherapy in front-line treatment of advanced ovarian cancer: a retrospective study of feasibility and efficacy. ESMO Open 2017; 1:e000117. [PMID: 28848659 PMCID: PMC5548979 DOI: 10.1136/esmoopen-2016-000117] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Revised: 11/23/2016] [Accepted: 11/23/2016] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Current standard neoadjuvant treatment for advanced ovarian cancer is 3-weekly platinum-based chemotherapy (CP3w). Patients unable to have interval debulking surgery (IDS) or with significant residual disease have a poor outcome to CP3w treatment. We investigated the outcome in patients who were switched to dose-dense chemotherapy. METHODS We retrospectively analysed 30 patients treated at UCLH in 2009-2013, who switched to dose-dense chemotherapy after neoadjuvant CP3w, having achieved a poor response/progressed and unable to proceed to IDS (n=21), or had >1 cm residual disease after IDS (n=9). Treatment was 3-weekly carboplatin and weekly paclitaxel (n=23), or both drugs weekly (n=7). For comparison, we included 30 matched patients treated with CP3w followed by IDS (n=24, without or ≤1 cm residual disease; n=6, with >1 cm residual disease). Time to progression (TTP) and overall survival (OS) were measured from the date of diagnosis until progression (CT scan or CA-125) and death from any cause, respectively. RESULTS Baseline characteristics were similar in both groups. The response rate to dose-dense chemotherapy was 70% (Gynecological Cancer Intergroup criteria). In the dose-dense group, 24 patients had tumour progression and 16 died; the corresponding numbers in the control group were 24 and 11. Median TTP was 15.8 months with dose-dense therapy, higher than expected for this patient group, and the same as in the control group (15.7 months) undergoing IDS, p=0.27. Median TTP in patients with residual disease postsurgery was 16.5 months (dose-dense) and 10.8 months (controls), p=0.02. TTP in dose-dense patients who did not have surgery was 10.4 months. Median OS was 31.3 (dose-dense) and 59.6 months (controls), p=0.06. Dose-dense chemotherapy was well tolerated: only three patients interrupted treatment due to toxicity. CONCLUSION Switching to dose-dense chemotherapy in patients who failed to respond to CT3w neoadjuvant chemotherapy appears to be an effective strategy and requires further investigation.

Abstract
Paclitaxel chemoresistance restricts the therapeutic efficacy and prognosis of patients with nasopharyngeal carcinoma (NPC). Accumulating evidence suggests that aberrant expression of long non-coding RNAs (lncRNAs) contributes to cancer progression. Therefore, we aimed to identify lncRNAs associated with paclitaxel resistance in NPC. First, paclitaxel-resistant CNE-2 cells (CNE-2-Pr) were successfully established and confirmed to be 33.26±8.70 times more resistant than parental CNE-2 cells. Then, differential expression profile of lncRNAs associated with NPC paclitaxel resistance, which contained a total of 2,670 known lncRNAs and 4,820 novel lncRNAs, was constructed via next generation sequencing technology. Our qRT-PCR confirmed that 7 of the top 8 lncRNAs were expressed with the same trend as the prediction, including 4 known lncRNAs (n375709, n377806, n369241 and n335785) and 3 novel lncRNAs (Unigene6646, Unigene6644 and Unigene1654). Our group initially focused on lncRNA n375709, which was the most significantly overexpressed lncRNA of the known lncRNAs. CCK-8 assays demonstrated that further inhibition of lncRNA n375709 increased the paclitaxel sensitivity in NPC 5-8F and 6-10B cells. In conclusion, the present study provided an overview of the expression profiles of lncRNAs correlated with paclitaxel resistance. lncRNA n375709 was identified to be involved in the regulation of NPC paclitaxel resistance.

Abstract
Supplemental digital content is available in the text. Objective Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome “resistance” in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. Methods Epirubicin, cisplatin, and capecitabine (ECX) combination chemotherapy was used at our institution for the treatment of relapsed EOC. From the institutional database, we identified all patients with primary platinum-refractory or platinum-resistant relapse treated with ECX as second-line therapy between 2001 and 2012. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used logistic and Cox regression models to identify predictors of response and survival respectively. Results Thirty-four 34 patients (8 refractory, 26 resistant) were treated with ECX. Response Evaluation Criteria In Solid Tumors (RECIST) response rate was 45%, median progression-free survival (PFS) was 6.4 months, and overall survival (OS) was 10.6 months. Platinum-resistant patients had better outcomes than did platinum-refractory patients (response rate, 54% vs 0%, P = 0.047; PFS 7.2 vs 1.8 months, P < 0.0001; OS 14.4 vs 3 months, P < 0.001). In regression models, time to progression after first-line treatment and platinum-refractory status were the strongest predictors of response and PFS or OS, respectively. Patients with time to progression after first-line treatment longer than 3 months showed PFS and OS of 7.9 and 14.7 months, respectively. Toxicity was manageable, with only 13% of cycles administered at reduced doses. Conclusions Epirubicin, cisplatin, and capecitabine seems to be active in platinum-resistant relapsed EOC with manageable toxicity. Further prospective investigation of platinum-anthracycline combinations is warranted in patients who relapse 3 to 6 months after first-line platinum-taxane treatment.

Abstract
Intensive cisplatin and oral etoposide for relapsed epithelial ovarian cancer (EOC), commonly known as the van der Burg (VDB) protocol, has been reported to improve response rates and progression-free survival. We report on all patients with relapsed EOC treated on the VDB protocol at the Cambridge Gynae-Oncology Centre. From the institutional databases, we identified all patients treated since 2001. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used Cox regression to identify predictors of survival. A total of 35 patients were treated on the VDB protocol. Toxicity was significant, with grade 3/4 fatigue, nausea and vomiting affecting 46, 46 and 29% of patients, respectively. Six patients had grade 3/4 infection and four (11%) deaths occurred on treatment. Efficacy was encouraging, with a radiological response rate of 43%, a median progression-free survival of 5.8 months and a median overall survival of 14.1 months. No significant difference in efficacy was seen between platinum-resistant and sensitive patients. We report significant activity of the VDB protocol in a routine clinical setting. However, the high rates of serious toxicity and treatment-related deaths among patients treated with palliative intent proved unacceptable. The Cambridge Gynae-Oncology Centre no longer uses this regimen in women with relapsed EOC.

Abstract
Dicycloplatin is a new generation supramolecular platinum-containing anti-cancer drug. Due to its structure, it is difficult to differentiate dicycloplatin from physical mixtures of carboplatin and cyclobutane dicarboxylate, and confounding results may arise during drug characterization. To solve this problem, this study aims to provide a reliable and reproducible standard for the determination of dicycloplatin. A simple method for dicycloplatin quality control has been developed using X-ray powder diffraction (XRPD) and high performance liquid chromatography (HPLC). XRPD allowed the control of impurities and dissociation of the dicycloplatin active ingredient to less than 1%, and HPLC allowed the monitoring and control of the relative molar ratio of carboplatin and cyclobutane dicarboxylate within the purity range. The study proved for the first time that the dicycloplatin supramolecule is substantially different from a physical mixture of carboplatin and cyclobutane dicarboxylate.

Abstract
Paclitaxel (Taxol) is currently used as the front-line chemotherapeutic drug for many types of human cancers. However, the emergence of drug resistance has been a major obstacle to the effective treatment of cancers in clinical settings. The transcription factor Forkhead box protein C2 (FOXC2) was recently demonstrated to activate the epithelial-mesenchymal transition (EMT). In this article, we present a novel role of FOXC2 in regulating chemoresistance of nasopharyngeal carcinoma (NPC) through the EMT. Using an EMT PCR array based on the screening of 84 genes, the expression of FOXC2 was notably upregulated in paclitaxel-resistant NPC cells (CNE2/t). We observed that the paclitaxel-resistant cells exhibited characteristic EMT phenotypes. The silencing of FOXC2 expression in the resistant cells can reverse the EMT molecular markers and chemoresistant phenotypes, such as cellular morphology, proliferation and anoikis. In an NPC xenograft mouse model, the downregulation of FOXC2 expression in the resistant NPC cells increased their sensitivity to paclitaxel treatment, resulting in reduced tumor growth. Taken together, our results suggest that FOXC2-mediated EMT may be an alternative mechanism through which cancer cells can initiate and maintain drug resistance. Thus, targeting FOXC2 may provide a novel strategy for overcoming chemoresistance in NPC therapy.

Abstract
Ephrin type-A receptor 2 (EphA2) is a receptor tyrosine kinase that is associated with cancer cell metastasis. There has been little investigation into its impact on the regulation of sensitivity to paclitaxel in nasopharyngeal carcinoma (NPC). In the present study, upregulation of EphA2 expression enhanced the survival of NPC 5-8F cells, compared with control cells exposed to the same concentrations of paclitaxel. Flow cytometry and western blot analysis demonstrated that over-expression of EphA2 decreased NPC cancer cell sensitivity to paclitaxel by regulating paclitaxel-mediated cell cycle progression but not apoptosis in vitro. This was accompanied by alterations in the expression of cyclin-dependent kinase inhibitors, p21 and p27, and of inactive phosphorylated-retinoblastoma protein. Furthermore, paclitaxel stimulation and EphA2 over-expression resulted in activation of the phosphoinositide 3-kinase (PI3K)/Akt signalling pathway in NPC cells. Inhibition of the PI3K/Akt signalling pathway restored sensitivity to paclitaxel in 5-8F cells over-expressing EphA2, which indicated that the PI3K/Akt pathway is involved in EphA2-mediated paclitaxel sensitivity. The current study demonstrated that EphA2 mediates sensitivity to paclitaxel via the regulation of the PI3K/Akt signalling pathway in NPC.

Long-term results of a randomised phase III trial of weekly versus three-weekly paclitaxel/platinum induction therapy followed by standard or extended three-weekly paclitaxel/platinum in European patients with advanced epithelial ovarian cancer. Eur J Cancer 2014; 50:2592-601. [PMID: 25096168 DOI: 10.1016/j.ejca.2014.07.015] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Revised: 07/04/2014] [Accepted: 07/08/2014] [Indexed: 11/23/2022]
Abstract
BACKGROUND Weekly paclitaxel/carboplatin might improve survival in platinum-resistant epithelial ovarian cancer (EOC). We compared efficacy of first-line weekly to three-weekly paclitaxel/cis- or carboplatin (PCw and PC3w) induction therapy, followed by either three or six PC3w cycles. PATIENTS AND METHODS In this multicentre, randomised phase III trial with 2×2 design, patients with FIGO stage IIb-IV EOC were randomised to six cycles PCw (paclitaxel 90mg/m(2), cisplatin 70mg/m(2) or carboplatin AUC 4) or three cycles PC3w (paclitaxel 175mg/m(2), cisplatin 75mg/m(2) or carboplatin AUC 6), followed by either three or six cycles PC3w. Primary endpoints were progression free survival (PFS) and overall survival (OS). Secondary endpoints were response rate (RR) and toxicity. RESULTS Of 267 eligible patients, 133 received PCw and 134 PC3w. The first 105 patients received cisplatin, after protocol amendment the subsequent 162 patients received carboplatin. Weekly cisplatin was less well tolerated than weekly carboplatin. All PC3w cycles were well tolerated. At the end of all treatments, RR was 90.8% with no differences between the treatment arms. After a follow-up of median 10.3years (range 7.1-14.8), median PFS was 18.5 (95% confidence interval (CI) 15.9-21.0) months for PCw and 16.4 (95% CI 13.5-19.2) months for PC3w (p=0.78). Median OS was 44.8 (95% CI 33.1-56.5) months for PCw and 41.1 (95% CI 34.4-47.7) months for PC3w (p=0.98). CONCLUSIONS There was no benefit in terms of OS, PFS or RR for a weekly regimen nor for extended chemotherapy as first-line treatment for EOC in European patients.

Abstract
PURPOSE Ovarian cancer has a high recurrence and mortality rate. A barrier to improved outcomes includes a lack of accurate models for preclinical testing of novel therapeutics. EXPERIMENTAL DESIGN Clinically relevant, patient-derived tumorgraft models were generated from sequential patients and the first 168 engrafted models are described. Fresh ovarian, primary peritoneal, and fallopian tube carcinomas were collected at the time of debulking surgery and injected intraperitoneally into severe combined immunodeficient mice. RESULTS Tumorgrafts demonstrated a 74% engraftment rate with microscopic fidelity of primary tumor characteristics. Low-passage tumorgrafts also showed comparable genomic aberrations with the corresponding primary tumor and exhibit gene set enrichment of multiple ovarian cancer molecular subtypes, similar to patient tumors. Importantly, each of these tumorgraft models is annotated with clinical data and for those that have been tested, response to platinum chemotherapy correlates with the source patient. CONCLUSIONS Presented herein is the largest known living tumor bank of patient-derived, ovarian tumorgraft models that can be applied to the development of personalized cancer treatment.

Abstract
A sensitive, simple and reproducible protocol for nanoparticle-assisted laser desorption/ionization mass spectrometry imaging technique is described. The use of commercially available TiO2 nanoparticles abolishes heterogeneous crystallization, matrix background interferences and enhances signal detection, especially in the low mass range. Molecular image normalization was based on internal standard deposition on tissues, allowing direct comparison of drug penetration and distribution between different organs and tissues. The method was applied to analyze the distribution of the anticancer drug paclitaxel, inside normal and neoplastic mouse tissue sections. Spatial resolution was good, with a linear response between different in vivo treatments and molecular imaging intensity using therapeutic drug doses. This technique distinguishes the different intensity of paclitaxel distribution in control organs of mice, such as liver and kidney, in relation to the dose. Animals treated with 30 mg/kg of paclitaxel had half of the concentration of those treated with 60 mg/kg. We investigated the spatial distribution of paclitaxel in human melanoma mouse xenografts, following different dosage schedules and found a more homogeneous drug distribution in tumors of mice given repeated doses (5×8 mg/kg) plus a 60 mg/kg dose than in those assigned only a single 60 mg/kg dose. The protocol can be readily applied to investigate anticancer drug distribution in neoplastic lesions and to develop strategies to optimize and enhance drug penetration through different tumor tissues.
