Abstract
Ovarian cancer (OC) is the highest worldwide cancer mortality cause among gynecologic tumors, but its underlying molecular mechanism remains largely unknown. Here, we report that the RNA binding protein A-kinase anchoring protein 8 (AKAP8) is highly expressed in ovarian cancer and predicts poor prognosis for ovarian cancer patients. AKAP8 promotes ovarian cancer progression through regulating cell proliferation and metastasis. Mechanically, AKAP8 is enriched at chromatin and regulates the transcription of the specific hnRNPUL1 isoform. Moreover, AKAP8 phase separation modulates the hnRNPUL1 short isoform transcription. Ectopic expression of the hnRNPUL1 short isoform could partially rescue the growth inhibition effect of AKAP8-knockdown in ovarian cancer cells. In addition, AKAP8 modulates PARP1 expression through hnRNPUL1, and AKAP8 inhibition enhances PAPR inhibitor cytotoxicity in ovarian cancer. Together, our study uncovers the crucial function of AKAP8 condensation-mediated transcription regulation, and targeting AKAP8 could be potential for improvement of ovarian cancer therapy.

Immunotherapy with IL12 and PD1/CTLA4 inhibition is effective in advanced ovarian cancer and associates with reversal of myeloid cell-induced immunosuppression. Oncoimmunology 2023; 12:2198185. [PMID: 37066116 PMCID: PMC10101660 DOI: 10.1080/2162402x.2023.2198185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 03/28/2023] [Accepted: 03/29/2023] [Indexed: 04/18/2023] Open
Abstract
The tumor microenvironment (TME) in ovarian cancer (OC) is characterized by immune suppression, due to an abundance of suppressive immune cells populations. To effectively enhance the activity of immune checkpoint inhibition (ICI), there is a need to identify agents that target these immunosuppressive networks while promoting the recruitment of effector T cells into the TME. To this end, we sought to investigate the effect of the immunomodulatory cytokine IL12 alone or in combination with dual-ICI (anti-PD1 + anti-CTLA4) on anti-tumor activity and survival, using the immunocompetent ID8-VEGF murine OC model. Detailed immunophenotyping of peripheral blood, ascites, and tumors revealed that durable treatment responses were associated with reversal of myeloid cell-induced immune suppression, which resulted in enhanced anti-tumor activity by T cells. Single cell transcriptomic analysis further demonstrated striking differences in the phenotype of myeloid cells from mice treated with IL12 in combination with dual-ICI. We also identified marked differences in treated mice that were in remission compared to those whose tumors progressed, further confirming a pivotal role for the modulation of myeloid cell function to allow for response to immunotherapy. These findings provide the scientific basis for the combination of IL12 and ICI to improve clinical response in OC.

Assessment of the diagnostic and prognostic relevance of ACAT1 and CE levels in plasma, peritoneal fluid and tumor tissue of epithelial ovarian cancer patients - a pilot study. BMC Cancer 2022; 22:387.

Abstract
Abstract
Background
Abnormal accumulation of acyl-CoA cholesterol acyltransferase-1 (ACAT1) and ACAT1-mediated cholesterol esterified with fatty acids (CE) contribute to cancer progression in various cancers. Our findings of increased CE and ACAT1 levels in epithelial ovarian cancer (EOC) cell lines prompted us to investigate whether such an increase occurs in primary clinical samples obtained from human subjects diagnosed with EOC. We evaluated the diagnostic/prognostic potential of ACAT1 and CE in EOC by: 1) assessing ACAT1 and CE levels in plasma, peritoneal fluid, and ovarian/tumor tissues; 2) assessing diagnostic performance by Receiver Operating Characteristic (ROC) analysis; and 3) comparing expression of ACAT1 and CE with that of tumor proliferation marker, Ki67.
Methods
ACAT1 protein levels in plasma, peritoneal fluid and tissue were measured via enzyme-linked immunosorbent assay. Tissue expression of ACAT1 and Ki67 proteins were confirmed by immunohistochemistry and mRNA transcript levels were evaluated using quantitative real-time polymerase chain reaction (qRT-PCR). CE levels were assessed in plasma, peritoneal fluid (colorimetric assay) and in tissue (thin layer chromatography).
Results
Preoperative levels of ACAT1 and CE on the day of surgery were significantly higher in tissue and peritoneal fluid from EOC patients vs. the non-malignant group, which included subjects with benign tumors and normal ovaries; however, no significant differences were observed in plasma. In tissue and peritoneal fluid, positive correlations were observed between CE and ACAT1 levels, as well as between ACAT1/CE and Ki67.
Conclusions
ACAT1 and CE accumulation may be linked to the aggressive potential of EOC; therefore, these mediators may be useful biomarkers for EOC prognosis and target-specific treatments.

Abstract
Tumor-associated macrophages (TAMs) promote metastasis and inhibit T cells, but macrophages can be polarized to kill cancer cells. Macrophage polarization could thus be a strategy for controlling cancer. We show that macrophages from metastatic pleural effusions of breast cancer patients can be polarized to kill cancer cells with monophosphoryl lipid A (MPLA) and interferon (IFN) γ. MPLA + IFNγ injected intratumorally or intraperitoneally reduces primary tumor growth and metastasis in breast cancer mouse models, suppresses metastasis, and enhances chemotherapy response in an ovarian cancer model. Both macrophages and T cells are critical for the treatment's anti-metastatic effects. MPLA + IFNγ stimulates type I IFN signaling, reprograms CD206+ TAMs to inducible NO synthase (iNOS)+ macrophages, and activates cytotoxic T cells through macrophage-secreted interleukin-12 (IL-12) and tumor necrosis factor alpha (TNFα). MPLA and IFNγ are used individually in clinical practice and together represent a previously unexplored approach for engaging a systemic anti-tumor immune response.

Abstract
BACKGROUND This study evaluates the outcomes and toxicity of stereotactic body radiation therapy (SBRT) in ovarian cancer. METHODS This retrospective analysis considered all patients treated with SBRT from 2009 to 2018 with a primary ovarian tumor. Follow-up included PET-CT and CT scans at 2-3 month intervals. Statistical analysis primarily consisted of univariate analysis, Cox proportional hazards analysis, and the Kaplan-Meier method. RESULTS The study included 35 patients with 98 treatments for lymph nodes (51), local recurrence (21), and de novo solid metastases (26). Median biologically effective dose (BED), gross tumor volume, and planning target volume were 38.40 Gy, 10.41 cc, and 25.21 cc, respectively. 52 lesions showed complete radiographic response, and two-year local control was 80%. Median overall survival (OS) was 35.2 months, and two-year progression-free survival (PFS) was 12%. On univariate analysis, Eastern Cooperative Oncology Group performance status > 0 was predictive of decreased OS (p = 0.0024) and PFS (p = 0.044). Factors predictive of local failure included lower BED (p = 0.016), treatment for recurrence (p = 0.029), and higher pre-treatment SUV (p = 0.026). Kaplan-Meier analysis showed BED ≤35 Gy (p < 0.005) and treatment for recurrence (p = 0.01) to be predictive of local failure. On Cox proportional hazards analysis, treatment of lymph nodes was predictive of complete radiographic response (hazard ratio (HR) = 4.95), as was higher BED (HR = 1.03). Toxicity included 27 cases of grade < 3 toxicity, and one grade 5 late toxicity of GI bleed from a radiation therapy-induced duodenal ulcer. CONCLUSIONS SBRT provides durable local control with minimal toxicity in ovarian cancer, especially with BED > 35 Gy and treatment for lymph nodes.

Abstract
BACKGROUND Adenosine released by cancer cells in high amounts in the tumour microenvironment is one of the main immunosuppressive agents responsible for the escape of cancer cells from immunological control. Blocking adenosine receptors with adenosine analogues and restoring immune cell activity is one of the methods considered to increase the effectiveness of anticancer therapy. However, their direct effects on cancer cell biology remain unclear. Here, we determined the effect of adenosine analogues on the response of cisplatinsensitive and cisplatin-resistant ovarian cancer cells to cisplatin treatment. METHODS The effects of PSB 36, DPCPX, SCH58261, ZM 241385, PSB603 and PSB 36 on cisplatin cytotoxicity were determined against A2780 and A2780cis cell lines. Quantification of the synergism/ antagonism of the compounds cytotoxicity was performed and their effects on the cell cycle, apoptosis/necrosis events and cisplatin incorporation in cancer cells were determined. RESULTS PSB 36, an A1 receptor antagonist, sensitized cisplatin-resistant ovarian cancer cells to cisplatin from low to high micromolar concentrations. In contrast to PSB 36, the A2AR antagonist ZM 241385 had the opposite effect and reduced the influence of cisplatin on cancer cells, increasing their resistance to cisplatin cytotoxicity, decreasing cisplatin uptake, inhibiting cisplatin-induced cell cycle arrest, and partly restoring mitochondrial and plasma membrane potentials that were disturbed by cisplatin. CONCLUSION Adenosine analogues can modulate considerable sensitivity to cisplatin of ovarian cancer cells resistant to cisplatin. The possible direct beneficial or adverse effects of adenosine analogues on cancer cell biology should be considered in the context of supportive chemotherapy for ovarian cancer.

Abstract
Abnormal accumulation of acyl-CoA cholesterol acyltransferase-1 (ACAT-1) mediated cholesterol ester has been shown to contribute to cancer progression in various cancers including leukemia, glioma, breast, pancreatic and prostate cancers. However, the significance of ACAT-1 and cholesterol esters (CE) is relatively understudied in ovarian cancer. In this in vitro study, we assessed the expression and contribution of ACAT-1 in ovarian cancer progression. We observed a significant increase in the expression of ACAT-1 and CE levels in a panel of ovarian cancer cell lines (OC-314, SKOV-3 and IGROV-1) compared to primary ovarian epithelial cells (normal controls). To confirm the tumor promoting capacity of ACAT-1, we inhibited ACAT-1 expression and activity by treating our cell lines with an ACAT inhibitor, avasimibe, or by stable transfection with ACAT-1 specific short hairpin RNA (shRNA). We observed significant suppression of cell proliferation, migration and invasion in ACAT-1 knockdown ovarian cancer cell lines compared to their respective controls (cell lines transfected with scrambled shRNA). ACAT-1 inhibition enhanced apoptosis with a concurrent increase in caspases 3/7 activity and decreased mitochondrial membrane potential. Increased generation of reactive oxygen species (ROS) coupled with increased expression of p53 may be the mechanism(s) underlying pro-apoptotic action of ACAT-1 inhibition. Additionally, ACAT-1 inhibited ovarian cancer cell lines displayed enhanced chemosensitivity to cisplatin treatment. These results suggest ACAT-1 may be a potential new target for the treatment of ovarian cancer.

Abstract
The low survival rate associated with serous ovarian carcinoma (SOC) is largely due to the lack of relevant molecular markers for early detection and therapy. Increasing experimental evidence has demonstrated that long noncoding RNAs (lncRNAs) are involved in cancer initiation and development, and a competitive endogenous RNA (ceRNA) hypothesis has been formulated. Therefore, the characterization of new lncRNA and lncRNA-related networks is crucial for early diagnosis and targeted therapy of SOC. Data on lncRNAs, mRNAs, and miRNAs with differential expression in SOC, compared to normal ovarian tissue, were obtained from the Gene Expression Omnibus (GEO) database. Data on lncRNA expression and clinical data in SOC were obtained from The Cancer Genome Atlas (TCGA). lncRNA-miRNA interactions were predicted by the miRBase database. Different online tools, i.e., TargetScan, RNA22, miRmap, microT, miRanda, StarBase, and PicTar, were cooperatively utilized to predict the mRNAs targeted by miRNAs. The plugin of BiNGO in Cytoscape and KOBAS 3.0 were used to conduct the functional and pathway enrichment analyses. The lncRNA, miRNAs, and mRNAs identified to be expressed at statistically significant and different levels between SOC and healthy fallopian tube tissues were further validated using qRT-PCR. A total of 4 lncRNAs (LINC00284, HAGLR, HCAT158, and BLACAT1) and 111 mRNAs were found to be upregulated in SOC tissues compared to normal tissues, based on the GEO database. LINC00284 was found to be highly expressed in SOC, in association with the upregulation of the transcription factor SOX9. The high LINC00284 expression was associated with poor prognosis and proved to be an independent risk factor in patients with SOC, based on TCGA database. The qRT-PCR validation results closely recapitulated the expression profiles and prognostic scores of the aforementioned bioinformatic analyses. The LINC00284-related ceRNA network was found to be associated with SOC carcinogenesis by biofunctional analysis. In conclusion, the LINC00284-related ceRNA network may provide valuable information on the mechanisms of SOC initiation and progression. Importantly, LINC00284 proved to be a new potential prognostic biomarker for SOC.

Abstract
Major progress in the analysis of human immune responses to cancer has been made through the molecular characterization of human tumour antigens. The development of therapeutic strategies for eliciting immune-mediated rejection of tumours has accelerated due to the elucidation of the molecular basis for tumour cell recognition and destruction by immune cells. Of the various human tumour antigens defined to date in ovarian cancer, the cancer-testis (CT) family of antigens have been studied extensively preclinically and clinically because of their testis-restricted expression in normal tissues and ability to elicit robust immune responses. Recent developments in cancer sequencing technologies offer a unique opportunity to identify tumour mutations with the highest likelihood of being expressed and recognized by the immune system. Such mutations, or neoantigens, could potentially serve as specific immune targets for T-cell-mediated destruction of cancer cells. This review will highlight current work in selecting tumour rejection antigens in ovarian cancer for improving the efficacy of immunotherapy.

Abstract
BACKGROUND Poly(ADP-ribose) polymerase (PARP) inhibitors are effective in a broad population of patients with ovarian cancer; however, resistance caused by low enzyme expression of the drug target PARP-1 remains to be clinically evaluated in this context. We hypothesize that PARP-1 expression is variable in ovarian cancer and can be quantified in primary and metastatic disease using a novel PET imaging agent. METHODS We used a translational approach to describe the significance of PET imaging of PARP-1 in ovarian cancer. First, we produced PARP1-KO ovarian cancer cell lines using CRISPR/Cas9 gene editing to test the loss of PARP-1 as a resistance mechanism to all clinically used PARP inhibitors. Next, we performed preclinical microPET imaging studies using ovarian cancer patient-derived xenografts in mouse models. Finally, in a phase I PET imaging clinical trial we explored PET imaging as a regional marker of PARP-1 expression in primary and metastatic disease through correlative tissue histology. RESULTS We found that deletion of PARP1 causes resistance to all PARP inhibitors in vitro, and microPET imaging provides proof of concept as an approach to quantify PARP-1 in vivo. Clinically, we observed a spectrum of standard uptake values (SUVs) ranging from 2-12 for PARP-1 in tumors. In addition, we found a positive correlation between PET SUVs and fluorescent immunohistochemistry for PARP-1 (r2 = 0.60). CONCLUSION This work confirms the translational potential of a PARP-1 PET imaging agent and supports future clinical trials to test PARP-1 expression as a method to stratify patients for PARP inhibitor therapy.

Abstract
Despite advances in various chemotherapy regimens, current therapeutic options are limited for ovarian cancer patients. Immunotherapy provides a promising and novel treatment option for ovarian cancer. Recently, chimeric antigen receptor (CAR) T cell therapy has shown promising results in hematological tumors and current research is going on in various solid tumors like ovarian cancer. CAR T cells are genetically engineered T cells with major histocompatibility complex-independent, tumor-specific, immune-mediated cytolytic actions against cancer cells. Initial studies of CAR T cell therapy have shown promising results in ovarian cancer, but there are some obstacles like impaired T cell trafficking, lack of antigenic targets, cytokine release syndrome and most important immunosuppressive tumor microenvironment. Optimization of design, improving tumor microenvironment and combinations with other therapies may help us in improving CAR T cell efficacy. In this review article, we highlight the current knowledge regarding CAR T cell therapy in ovarian cancer. We have discussed basic functioning of CAR T cells, their rationale and clinical outcome in ovarian cancer with limitations.

Abstract
BACKGROUND Epithelial ovarian cancer (EOC) remains the most lethal gynecologic malignancy. The objective of this study was to compare the anti-tumor activity of HER2/neu-targeting monoclonal antibodies, trastuzumab (T), pertuzumab (P), combination of trastuzumab and pertuzumab (T+P) and trastuzumab-emtansine (T-DM1) in EOC with high HER2/neu expression. METHODS Primary EOC cell lines were established and cell blocks were analyzed for HER2/neu expression. Cytostatic, apoptotic and antibody-dependent cell-mediated cytotoxicity (ADCC) activities of T, P, T+P and T-DM1 were evaluated in vitro. The in vivo antitumor activity was tested in xenograft models with 3+ HER2/neu expression. RESULTS High (3+) HER2/neu expression was detected in 40% of the primary EOC cell lines. T, P, T+P, and T-DM1 were similarly effective in inducing strong ADCC against primary EOC cell lines expressing 3+ HER2/neu. The combination of T and P was more cytostatic when compared with that of T or P used alone (p<0.0001 and p<0.0001, respectively). T-DM1 induced significantly more apoptosis when compared with T+P (p<0.0001). Finally, T-DM1 was significantly more effective in tumor growth inhibition in vivo in EOC xenografts overexpressing HER2/neu when compared to T alone, P alone and T+P (p=0.04). CONCLUSION In vitro and in vivo experiments with 3+ HER2/neu expressing EOC revealed limited anti-tumor activity of T or P. T-DM1 showed superior anti-tumor activity to T and P as single agents and as a combination. Our preclinical data support the design of clinical studies with T-DM1 for the treatment of chemotherapy-resistant EOC overexpressing HER2/neu.

Abstract
Cisplatin treatment some times leads to chemoresistance, which is now acknowledged partially due to the inductive expression of progesterone receptor membrane component (PGRMC)1 in ovarian cancer cells. PGRMC1 enhances autophagy, activates cytochrome p450, and inveigles signaling pathways to promote cell survival and reduce the effect of drug treatments. In this study, we give first line evidence that hyperoside inhibits cell viability, triggers autophagy and apoptosis in ovarian cancer cell lines. Mechanistically, PGRMC1-dependent autophagy was utilized by hyperoside to induce apoptotic cell death. Hyperoside induced the conversion of LC3B-I to LC3B-II and the formation of autophagosomes in ovarian cancer cells. Notably, PGRMC1 colocolized with LC3B‑II, and PGRMC1 overexpression enhanced hyperoside-induced autophagy and apoptosis, while PGRMC1 knockdown abrogated the action. Additionally, AKT signaling and Bcl-2 family were also involved in the hyperoside-induced autophagy and apoptosis. Importantly, in cisplatin-resistant ovarian cancer cells where PGRMC1 was overexpressed, hyperoside sensitized the cells to cisplatin treatment. Together these findings indicate hyperoside functions as a complementary therapy for ovarian cancer patients receiving platinum-based therapy.

Abstract
MicroRNAs (miRNAs) function as critical regulators of gene expression and their deregulation is associated with the development and progression of various cancers. This study aimed to investigate the biological role and mechanism of miR-205 in ovarian cancer (OC). MiR-205 was upregulated in OC tissues and cells in comparison to the controls. Meanwhile, overexpression of miR-205 was significantly associated with poor overall survival of OC patients. Functional study indicated that ectopic expression of miR-205 significantly promoted cell proliferation, migration, invasion and chemoresistance of OC cells. SMAD4 and PTEN were identified as direct targets of miR-205 using luciferase reporter assays, real-time PCR (qRT-PCR), and western blot. Most interestingly, in vivo studies indicated that miR-205 markedly promoted the growth and metastasis of tumors and the expression of miR-205 was also found to be inversely correlated with that of SMAD4 and PTEN in nude mice. Overall, we suggest that miR-205 functions as an oncogenic miRNA by directly binding to SMAD4 and PTEN, providing a novel target for the molecular treatment of ovarian cancer.

Abstract
Background Combination drug therapy appears a promising approach to overcome drug resistance and reduce drug-related toxicities in ovarian cancer treatments. In this in vitro study, we evaluated the antitumor efficacy of cisplatin in combination with Bithionol (BT) against a panel of ovarian cancer cell lines with special focus on cisplatin-sensitive and cisplatin-resistant cell lines. The primary objectives of this study are to determine the nature of the interactions between BT and cisplatin and to understand the mechanism(s) of action of BT-cisplatin combination. Methods The cytotoxic effects of drugs either alone or in combination were evaluated using presto-blue assay. Cellular reactive oxygen species were measured by flow cytometry. Immunoblot analysis was carried out to investigate changes in levels of cleaved PARP, XIAP, bcl-2, bcl-xL, p21 and p27. Luminescent and colorimetric assays were used to test caspases 3/7 and ATX activity. Results The efficacy of the BT-cisplatin combination depends upon the cell type and concentrations of cisplatin and BT. In cisplatin-sensitive cell lines, BT and cisplatin were mostly antagonistic except when used at low concentrations, where synergy was observed. In contrast, in cisplatin-resistant cells, BT-cisplatin combination treatment displayed synergistic effects at most of the drug ratios/concentrations. Our results further revealed that the synergistic interaction was linked to increased reactive oxygen species generation and apoptosis. Enhanced apoptosis was correlated with loss of pro-survival factors (XIAP, bcl-2, bcl-xL), expression of pro-apoptotic markers (caspases 3/7, PARP cleavage) and enhanced cell cycle regulators p21 and p27. Conclusion In cisplatin-resistant cell lines, BT potentiated cisplatin-induced cytotoxicity at most drug ratios via enhanced ROS generation and modulation of key regulators of apoptosis. Low doses of BT and cisplatin enhanced efficiency of cisplatin treatment in all the ovarian cancer cell lines tested. Our results suggest that novel combinations such as BT and cisplatin might be an attractive therapeutic approach to enhance ovarian cancer chemosensitivity. Combining low doses of cisplatin with subtherapeutic doses of BT can ultimately lead to the development of an innovative combination therapy to reduce/prevent the side effects normally occurring when high doses of cisplatin are administered.

Abstract
Ovarian cancer is a gynecological malignancy with high mortality rates worldwide and novel diagnostic and prognostic markers and therapeutic targets are urgently required. The suppressor of cytokine signaling 1 (SOCS1) and cyclin-dependent kinase inhibitor 1A (p21KIP) are known to regulate tumor cell proliferation. However, the mechanisms that regulate these genes have not yet been completely elucidated. In the present study, analysis of a published microarray-based high-throughput assessment (NCBI/E-MTAB-1067) and real-time PCR demonstrated that miR-572 was upregulated in human ovarian cancer tissues and cell lines. Kaplan-Meir analysis indicated that high level expression of miR-572 was associated with poorer overall survival. Ectopic miR-572 promoted ovarian cancer cell proliferation and cell cycle progression in vitro and tumorigenicity in vivo. SOCS1 and p21 were identified as direct targets of miR-572 and suppression of SOCS1 or p21 reversed the inhibiting-function of miR-572-silenced cell on proliferation and tumorigenicity in ovarian cancer cells. Additionally, the expression of miR-572 correlated inversely with the protein expression levels of SOCS1, p21 and positively with Cyclin D1 in ovarian carcinoma specimens. This study demonstrates that miR-572 post-transcriptionally regulates SOCS1 and p21 and may play an important role in ovarian cancer progression; miR-572 may represent a potential therapeutic target for ovarian cancer therapy.

Abstract
Ovarian cancers diagnosed between 2000 and 2013 were examined and cases with and without endometriosis compared. Among 139 epithelial ovarian, there were 49 (35%) with endometriosis and 90 (65%) without endometriosis. Endometriosis associated ovarian cancers were more likely to be confined to the pelvis (54% vs. 9%, p < 0.0001) and lower grade (51% vs. 29%, p = 0.014). Younger age and earlier stage independently predicted the presence of endometriosis (p = 0.0011 and p < 0.0001, respectively). Ovarian cancer patients with endometriosis had improved PFS and OS [(HR = 0.20; 95% CI, 0.09-0.43), (HR = 0.18; 95% CI, 0.04-0.81)], compared to patients without endometriosis; however, endometriosis had no independent prognostic significance.

Abstract
UNLABELLED Approximately 50% of epithelial ovarian cancers (EOC) exhibit defective DNA repair via homologous recombination (HR) due to genetic and epigenetic alterations of HR pathway genes. Defective HR is an important therapeutic target in EOC as exemplified by the efficacy of platinum analogues in this disease, as well as the advent of PARP inhibitors, which exhibit synthetic lethality when applied to HR-deficient cells. Here, we describe the genotypic and phenotypic characteristics of HR-deficient EOCs, discuss current and emerging approaches for targeting these tumors, and present challenges associated with these approaches, focusing on development and overcoming resistance. SIGNIFICANCE Defective DNA repair via HR is a pivotal vulnerability of EOC, particularly of the high-grade serous histologic subtype. Targeting defective HR offers the unique opportunity of exploiting molecular differences between tumor and normal cells, thereby inducing cancer-specific synthetic lethality; the promise and challenges of these approaches in ovarian cancer are discussed in this review.

Abstract
Ovarian cancer (OC) is the seventh most common cancer in women worldwide, and the leading cause of death from gynaecological malignancy. Immunotherapeutic strategies including cancer vaccines are considered less toxic and more specific than current treatments. Sperm surface protein (Sp17) is a protein aberrantly expressed in primary as well as in metastatic lesions in >83% of ovarian cancer patients. Vaccines based on the Sp17 protein are immunogenic and protective in animal models. To map the immunogenic regions and support the development of human Sp17 peptide based vaccines, we used 6 overlapping peptides of the human Sp17 sequence adjuvanted with CpG to immunise humanised HLA-A2.1 transgenic C57BL/6 mice, and assessed immunogenicity by ELISPOT and ELISA. No CD8 T cells were found to be induced to a comprehensive panel of 10 HLA-A2.1 or H-2K(b) binding predicted epitopes. However, one of the 6 peptides, hSp17111-142, induced high levels of antibodies and IFN-γ producing T cells (but not IL-17 or IL-4) both in C57BL/6 and in C57BL/6-HLA-A2.1 transgenic mice. C57BL/6 mice immunised with CpG adjuvanted hSp17111-142 significantly prolonged the life-span of the mice bearing the ovarian carcinoma ID8 cell line. We further mapped the immuno-dominant B and T cell epitope regions within hSp17111-142 using ELISPOT and competition ELISA. Herein, we report the identification of a single immuno-dominant B cell (134-142 aa) epitope and 2 T helper 1 (Th1) cell epitopes (111-124 aa and 124-138 aa). These result together support further exploration of hSp17111-142 peptide formulations as vaccines against ovarian cancer.

Abstract
Despite advances in combinatorial chemotherapy regimens and the advent of intraperitoneal chemotherapy administration, current therapeutic options for ovarian cancer patients are inadequate. Immunotherapy offers a novel and promising therapeutic strategy for treating ovarian tumors. Following the demonstration of the immunogenicity of ovarian tumors, multiple immunotherapeutic modalities have been developed. Antibody-based therapies, immune checkpoint blockade, cancer vaccines, and chimeric antigen receptor-modified T cells have demonstrated preclinical success and entered clinical testing. In this review, we discuss these promising immunotherapeutic approaches and emphasize the importance of combinatorial treatment strategies and biomarker discovery.

Abstract
OBJECTIVES Epithelial ovarian cancer (EOC) is an aggressive disease in which first line therapy consists of a surgical staging/debulking procedure and platinum based chemotherapy. There is significant interest in clinically applicable, easy to use prognostic tools to estimate risk of recurrence and overall survival. In this study we used a large prospectively collected cohort of women with EOC to validate currently published models and assess prognostic variables. METHODS Women with invasive ovarian, peritoneal, or fallopian tube cancer diagnosed between 2000 and 2011 and prospectively enrolled into the Mayo Clinic Ovarian Cancer registry were identified. Demographics and known prognostic markers as well as epidemiologic exposure variables were abstracted from the medical record and collected via questionnaire. Six previously published models of overall and recurrence-free survival were assessed for external validity. In addition, predictors of outcome were assessed in our dataset. RESULTS Previously published models validated with a range of c-statistics (0.587-0.827), though application of models containing variables which are not part of routine practice were somewhat limited by missing data; utilization of all applicable models and comparison of results are suggested. Examination of prognostic variables identified only the presence of ascites and ASA score to be independent predictors of prognosis in our dataset, albeit with marginal gain in prognostic information, after accounting for stage and debulking. CONCLUSIONS Existing prognostic models for newly diagnosed EOC showed acceptable calibration in our cohort for clinical application. However, modeling of prospective variables in our dataset reiterates that stage and debulking remains the most important predictors of prognosis in this setting.

Abstract
Background Drug resistance is a cause of ovarian cancer recurrence and low overall survival rates. There is a need for more effective treatment approaches because the development of new drug is expensive and time consuming. Alternatively, the concept of ‘drug repurposing’ is promising. We focused on Bithionol (BT), a clinically approved anti-parasitic drug as an anti-ovarian cancer drug. BT has previously been shown to inhibit solid tumor growth in several preclinical cancer models. A better understanding of the anti-tumor effects and mechanism(s) of action of BT in ovarian cancer cells is essential for further exploring its therapeutic potential against ovarian cancer. Methods The cytotoxic effects of BT against a panel of ovarian cancer cell lines were determined by Presto Blue cell viability assay. Markers of apoptosis such as caspases 3/7, cPARP induction, nuclear condensation and mitochondrial transmembrane depolarization were assessed using microscopic, FACS and immunoblotting methods. Mechanism(s) of action of BT such as cell cycle arrest, reactive oxygen species (ROS) generation, autotaxin (ATX) inhibition and effects on MAPK and NF-kB signalling were determined by FACS analysis, immunoblotting and colorimetric methods. Results BT caused dose dependent cytotoxicity against all ovarian cancer cell lines tested with IC50 values ranging from 19 μM – 60 μM. Cisplatin-resistant variants of A2780 and IGROV-1 have shown almost similar IC50 values compared to their sensitive counterparts. Apoptotic cell death was shown by expression of caspases 3/7, cPARP, loss of mitochondrial potential, nuclear condensation, and up-regulation of p38 and reduced expression of pAkt, pNF-κB, pIκBα, XIAP, bcl-2 and bcl-xl. BT treatment resulted in cell cycle arrest at G1/M phase and increased ROS generation. Treatment with ascorbic acid resulted in partial restoration of cell viability. In addition, dose and time dependent inhibition of ATX was observed. Conclusions BT exhibits cytotoxic effects on various ovarian cancer cell lines regardless of their sensitivities to cisplatin. Cell death appears to be via caspases mediated apoptosis. The mechanisms of action appear to be partly via cell cycle arrest, ROS generation and inhibition of ATX. The present study provides preclinical data suggesting a potential therapeutic role for BT against recurrent ovarian cancer.

Abstract
The synthesis, characterization, and in vitro evaluation of a combination delivery of multiblock poly(N-2-hydroxypropyl)methacrylamide (HPMA), gemcitabine (GEM) and paclitaxel (PTX) conjugates is described in this study. Multiblock copolymer conjugates of a large molecular weight (Mw>200 kDa) were studied and compared to traditional, small molecular weight (Mw<45 kDa) conjugates. Stability of the conjugates in different pH was assessed, and their cytotoxicity in combination toward A2780 human ovarian cancer cells was evaluated by combination index analysis. Treatment duration (4 and 72 h) and sequence of addition were explored. In addition, an HPMA copolymer conjugate with both GEM and PTX in the side chains was evaluated in a similar manner and compared to a physical mixture of individual conjugates. Conjugates with narrow molecular weight distribution (Mw/Mn<1.1) were obtained via RAFT polymerization, and drug loadings of between 5.5 and 9.2 wt% were achieved. Conjugates demonstrated moderate stability with less than 65% release over 24h at pH 7.4, and near complete drug release in the presence of the lysosomal enzyme cathepsin B in 3h. In combination, the cytotoxic effects of a mixture of the conjugates were primarily additive. Synergistic effects were observed when A2780 human ovarian cancer cells were treated simultaneously for 4h with multiblock conjugates (CI<0.7). When both GEM and PTX were conjugated to the same copolymer backbone, moderate antagonism (CI 1.3-1.6) was observed. These results demonstrate that multiblock HPMA copolymer-GEM and -PTX conjugates, when delivered as a mixture of individual agents, are promising for the treatment of ovarian cancer.

Abstract
A characteristic feature of cancer cells is the activation of de novo fatty acid synthesis. Acetyl‑CoA carboxylase (ACC) is a key enzyme in fatty acid synthesis, accelerating the reaction that carboxylates cytosolic acetyl‑CoA to form malonyl‑CoA. ACC is highly expressed in several types of human cancer and is important in breast and prostate cancer cell growth. The aim of the present study was to investigate the effects of 5‑tetradecyloxy‑2‑furoic acid (TOFA), an allosteric inhibitor of ACC, on the proliferation and cell cycle progression of the ovarian cancer cell lines COC1 and COC1/DDP. TOFA was found to be cytotoxic to COC1 and COC1/DDP cells with a 50% inhibitory concentration (IC50) of ~26.1 and 11.6 µg/ml, respectively. TOFA inhibited the proliferation of the cancer cells examined in a time‑ and dose‑dependent manner, arrested the cells in the G0/G1 cell cycle phase and induced apoptosis. The expression of the cell cycle regulating proteins cyclin D1 and cyclin-dependent kinase (CDK) 4, as well as the expression of the apoptosis‑related proteins caspase‑3 and Bcl‑2, were detected by western blot analysis. Cyclin D1, CDK4 and Bcl‑2 protein expression was inhibited by TOFA, while caspase‑3 was cleaved and activated. To the best of our knowledge, the present study demonstrated for the first time that TOFA inhibits COC1/DDP cell growth in ovarian tumor mouse xenografts. By inhibiting ACC, TOFA may be a promising small molecule agent for ovarian cancer therapy.

Abstract
The ability of histone deacetylase inhibitors to modulate the expression of genes relevant for growth or apoptotis regulation supports their interest in combination treatments of resistant tumors. We explored the effect of the combination of the histone deacetylase inhibitor ST2782 and the proteasome inhibitor bortezomib in ovarian carcinoma cell lines, including the IGROV-1 cell line and two p53 mutant platinum-resistant sublines (IGROV-1/OHP and IGROV-1/Pt1). We found a synergistic interaction between the two drugs, more evident in the p53-mutant resistant sublines, which was associated with increa sed apoptosis. The treatment with ST2782 resulted in early induction of Bax as well as in cleavage of caspase 3 and poly (ADP-ribose) polymerase only in the resistant cell lines. The inhibition of p53-transcriptional transactivation by pifithrin alpha in IGROV-1 cells enhanced the synergism. Conversely, knockdown of endogenous wild-type p53 in IGROV-1 cells determined synergism reduction. These opposite effects support the relevance of the transactivation-deficient mutant p53 as a synergism determinant. Moreover, in vivo studies indicated that tumor growth inhibition tended to be more evident in mice receiving the drug combination than in those treated with bortezomib alone. Overall, our study supports the potential effectiveness of the combination in platinum drug-resistant ovarian cancer carrying mutant p53.

Abstract
Epithelial ovarian cancer remains the most lethal gynecologic malignancy despite advances in treatment. The standard management generally involves a combination of surgical tumor debulking and chemotherapy. Over the decades, chemotherapy for ovarian cancer has evolved and currently involves a combination of intravenous platinum and taxane chemotherapy. Over the past decade, three randomized phase III trials have been reported, and all have demonstrated a significant survival advantage for intraperitoneal compared with intravenous chemotherapy. However, there are potential barriers and controversies related to the administration of intraperitoneal chemotherapy in ovarian cancer patients. In this review, we discuss the evolution and current management considerations of chemotherapy for the treatment of epithelial ovarian cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The decoction of the whole plant of Physalis minima L. is traditionally consumed to treat cancer. Its anticancer property has been previously verified (using in vitro cytotoxicity assays) against NCI-H23 lung, CORL23 lung and MCF7 breast cancer cell lines but the mechanism underlying the anticancer potency towards ovarian carcinoma cells remain unclear. AIM OF THE STUDY The present study is aimed to systematically determine the cytotoxicity and possible cell death mechanism elicited by the chloroform extract of Physalis minima in human ovarian Caov-3 carcinoma. MATERIALS AND METHODS Cytotoxicity of the extract was measured using the methylene blue assay. The mechanism of cell death was determined using four independent methods, namely DeadEnd assay to label the DNA fragmentation nuclei cells, RT-PCR analysis to determine the mRNA expression level of three apoptotic genes (c-myc, p53 and caspase-3 genes), Transmission Electron Microscope (TEM) analysis to describe the ultra structural characteristics and annexin V and propidium iodide staining to confirm the types and stages of cell deaths. RESULTS Cytotoxicity screening of the extract on Caov-3 cells exhibited concentration- and time-dependent inhibitory effects. A combination of apoptotic and autophagic programmed cell death was detected. The apoptotic characteristic was initially determined by DNA fragmentation followed by the expression of c-myc and p53 genes that was much earlier than caspase-3. Apoptotic ultra structural changes (including clumping and magination of chromatin, blebbing and convolution of nucleus membrane and formation of apoptotic bodies) and autophagy (Type II non-apoptotic programmed cell death) with distinct vacuolated morphology were detected in TEM analysis. The existence of these programmed cell deaths was then corroborated using annexin V and propidium iodide staining. CONCLUSIONS The chloroform extract of Physalis minima exerted anticancer effect due to a combination of apoptotic and autophagic cell death mechanisms on Caov-3 cells. The induction of these programmed cell deaths was mediated via c-myc, p53 and caspase-3 dependent pathway. The results could provide a valuable insight in cancer therapy.

Abstract
The current treatment of choice of epithelial ovarian cancer involves aggressive tumor cytoreductive surgery followed by platinum- and taxane-based chemotherapy; however, despite the encouraging activity of these agents, most ovarian carcinomas relapse and many patients die from drug-resistant disease. After the failure of platinum- and taxane-based schedules, several cytotoxic agents have demonstrated activity in advanced ovarian cancer but none were able to induce significant and durable responses. Among the new cytotoxic agents, pemetrexed plays an emerging role in different tumors, demonstrating competitive activity and a promising safety profile. In ovarian cancer, pemetrexed has been investigated, with encouraging results, as a single agent and in association with platinum compounds; moreover, the drug has shown interesting activity both in platinum-sensitive and platinum-resistant ovarian cancer. According to these clinical results it appears reasonable to explore the combination of pemetrexed with other cytotoxic agents and also with targeted therapies in relapsed ovarian cancer patients.

Increased levels and defective glycosylation of MRPs in ovarian carcinoma cells resistant to oxaliplatin. Biochem Pharmacol 2009; 79:1108-17. [PMID: 20005867 DOI: 10.1016/j.bcp.2009.12.002] [Citation(s) in RCA: 79] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2009] [Revised: 12/01/2009] [Accepted: 12/02/2009] [Indexed: 12/15/2022]
Abstract
Pt compounds still represent the mainstay of the treatment of ovarian carcinoma. The aim of the present study was to investigate the molecular bases of resistance to Pt drugs using an oxaliplatin-resistant ovarian carcinoma cell model IGROV-1/OHP. These cells exhibited high levels of resistance to oxaliplatin, cross-resistance to cisplatin and topotecan and displayed a marked accumulation defect of Pt drugs. This feature was associated with increased expression and altered N-linked glycosylation of ATP binding cassette transporters MRP1 and MRP4. Pre-treatment with tunicamycin, which inhibits the biosynthesis of N-linked oligosaccharides, decreased the accumulation of Pt in sensitive cells exposed to oxaliplatin or cisplatin and increased the electrophoretic mobility of MRP1 and MRP4, reproducing the association between decreased glycosylation of MRP1 and MRP4 and decreased Pt accumulation observed in the resistant IGROV-1/OHP cells. The observed N-glycosylation defect of oxaliplatin-resistant cells was linked to reduced levels of N-acetylglucosamine-1-phosphotransferase (GNPTG) and mannosyl (alpha-1,6-)-glycoprotein beta-1,6-N-acetyl-glucosaminyltransferase (MGAT5). This feature, observed in IGROV-1/OHP cells, was associated with decreased retention of Pt drugs. In addition, the overexpression of fully glycosylated MRP1 or MRP4 in tumor cell line of ovarian origin was associated with resistance to oxaliplatin and cisplatin. Our findings, showing that development of resistance to oxaliplatin results in up-regulation of MRPs, support that patients with oxaliplatin-refractory ovarian carcinomas may benefit from non-Pt-based regimens which do not contain MRP1 and MRP4 substrates.

Abstract
OBJECTIVE To evaluate the efficacy of pegylated liposomal doxorubicin (PLD) and continuous infusion ifosfamide (IFO) in ovarian cancer patients who relapse within 1 year after first-line paclitaxel-platinum-based chemotherapy. METHODS Patients were stratified according to treatment-free interval (TFI) (<or >or=6 months). PLD (40 mg/m(2), day 1), IFO (1700 mg/m(2), infusion days 1-3), and mesna were given every 28 days for 6-9 cycles. Primary endpoint was objective response rate (ORR). Secondary endpoints were response duration, progression free survival (PFS), overall survival (OS), and toxicity. RESULTS There were 98 evaluable patients (58%, TFI<6 months). Median number of cycles was 5 (range: 1-9). The frequency of grade 3/4 anemia, thrombocytopenia, and neutropenia was 7%, 3%, and 48%, respectively; febrile neutropenia was 3%. A low rate of grade 3/4 non-hematologic toxicities was reported, including nausea/vomiting (3/4%), hand-foot syndrome (2%), and mucositis (2%). The ORR was 28% (41% and 19% in patients with TFI >or=6, or <6 months, respectively); rate of disease stabilization was 26%; response duration and median OS were 6 (2.4-26) and 14 (1-46) months, respectively. CONCLUSION The combination of PLD and continuous IFO is a feasible and efficient treatment in patients with relapsed ovarian cancer, especially with TFI between 6 and 12 months. This regimen may represent an alternative to platinum reintroduction and should be evaluated in a randomized trial.

Is the current concept of recurrent ovarian carcinoma as a chronic disease also applicable in platinum resistant patients? Arch Gynecol Obstet 2009; 281:339-44. [PMID: 19554341 DOI: 10.1007/s00404-009-1159-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2009] [Accepted: 06/09/2009] [Indexed: 12/19/2022]
Abstract
PURPOSE The treatment of recurrent ovarian carcinoma (ROC) has become increasingly oriented according to the therapy principles of a chronic disease. We evaluated whether it is justifiable to also apply this concept to the treatment of platinum resistant patients with their known poor prognosis and short overall survival (OS). METHODS We analyzed the overall courses of 85 unselected ROC patients and defined the following groups: A, platinum resistant patients (n=39); subgroup A.1, those who received no or at maximum one line of palliative chemotherapy (n=15, 38.5%); subgroup A.2, those who received>or=two therapy lines (n=24, 61.5%); B, platinum sensitive patients, n=46. RESULTS Group A had significantly lower OS than group B (median: 16 vs. 25 months; p=0.019). Group A.1 had significantly worse outcome compared to group A.2 (median: 5 vs. 21.5 months; p<0.001). The comparison between study group A.2 and group B showed comparable survival rates (p=0.738). Considering only the patients who had completed treatment courses, the median number of therapy lines administered was higher in group A.2 than in group B (4 vs. 3; p=0.008). CONCLUSIONS There is not only the known dichotomy between platinum sensitive and resistant ROC patients, but rather also within the platinum resistant subgroup itself. There is a considerably large subgroup of platinum resistant patients who will subsequently enter a phase where multiple treatment programs will be considered and administered. These patients have similar survival rates compared to those from the platinum sensitive patient group and the therapy principles of a chronic disease are applicable.

Abstract
BACKGROUND The prototypical antiprogestin mifepristone exhibits potent growth inhibition activity towards ovarian cancer cells in vitro and in vivo. The aim of this research was to establish whether mifepristone is capable of inhibiting cell proliferation and inducing apoptotic cell death regardless of the degree of sensitivity ovarian cancer cells exhibit to cisplatin. METHODS OV2008, OV2008/C13, A2780, A2780/CP70, Caov-3, and SK-OV-3 cell lines exhibiting a range of sensitivities to cisplatin were used. Growth inhibition, cell viability, and sub-diploid DNA content in response to treatment with escalating doses of either mifepristone or cisplatin were assessed by microcapillary cytometry. Apoptotic cell death was evaluated by measuring genomic DNA fragmentation and cleavage of caspase-3 and poly (ADP ribose) polymerase (PARP). RESULTS The sensitivities to cisplatin manifested by the cell lines were OV2008 > A2780 > Caov-3 > SK-OV-3 > OV2008/C13 > A2780/CP70. Mifepristone inhibited the growth of all six cell lines in a dose-related manner with IC50s ranging from ~6-12 muM and without significant correlation with the relative sensitivities the cells displayed for cisplatin. Moreover, at the highest concentration studied, mifepristone triggered apoptotic death in all six cell lines as evidenced by the increase in sub-diploid fragmented DNA content and cleavage of caspase-3 and of its downstream substrate PARP. CONCLUSION Mifepristone is cytotoxic towards ovarian cancer cells independent of the sensitivity exhibited by the cells to cisplatin, displaying cytostatic effects at lower concentrations and lethal effects at higher concentrations. Mifepristone monotherapy emerges as a valuable therapeutic alternative for platinum-resistant ovarian cancers.

Abstract
OBJECTIVE HIV patients taking antiretroviral protease inhibitors have a lower incidence of infection-associated malignancies, leading to the hypothesis that these drugs have antineoplastic activity. Given the need for novel treatment approaches in ovarian cancer, we sought to determine whether the protease inhibitor saquinavir has antineoplastic activity in ovarian cancer cell lines, and to elucidate the mechanism through which this occurs. METHODS A panel of ovarian cancer cell lines was treated with saquinavir. The effect of saquinavir on cell growth, viability, apoptotic and non-apoptotic cell death was determined. Stimulation of endoplasmic reticulum stress (ERS) response was assessed by immunoblotting for ERS regulators GRP78 and ATF6. Induction of autophagy was assessed using transmission electron microscopy (TEM), and confocal microscopy was performed to demonstrate changes in green fluorescent protein-labeled LC3 expression patterns. RESULTS Saquinavir induced cell death in chemosensitive and chemoresistant ovarian cancer cells in a time- and dose-dependent manner. Saquinavir treatment resulted in caspase-dependent apoptosis and caspase-independent cell death characterized by induction of ERS and autophagy. Cellular morphology assessed by TEM revealed apoptotic, autophagic, and necrotic cell death. CONCLUSIONS Saquinavir is an FDA-approved agent for the treatment of HIV, and our data suggest that it may also have clinical application in the treatment of ovarian cancer. Saquinavir induces endoplasmic reticulum stress, autophagy, and apoptosis in ovarian cancer cells. Given the challenges of chemoresistance in ovarian cancer, saquinavir may have particular benefit in the treatment of chemoresistant tumors that may respond to the induction of caspase-independent cell death by mechanisms such as autophagy.

Abstract
OBJECTIVE To assess the efficacy and toxicity profile in patients with recurrent ovarian or primary peritoneal cancer treated with topotecan at 2.5 mg/m(2) days 1 and 8 plus vinorelbine at 25 mg/m(2) days 1 and 8 every 3 weeks. MATERIALS AND METHODS Eligibility criteria included patients with recurrent primary peritoneal or epithelial ovarian cancer with either platinum-resistant or platinum-sensitive disease. Patients were required to have a performance status of <or=2 and normal hepatic and renal function. Response to therapy and toxicity were assessed using standard criteria. Chi square and Student's t-tests were used as appropriate. Survival was assessed with Kaplan-Meier method. RESULTS All 40 patients enrolled were assessable for response. The median age of the patients was 58 years (range 30-82). Median treatment-free interval was 4.0 months. A total of 216 cycles of chemotherapy were administered with a median of 5.0 cycles per patient. Overall median TTP with this treatment regimen was 19 weeks (range 2-136 weeks). The response rate was 30% overall, and the response for platinum-sensitive and platinum-resistant patients was 44% (95% CI:22-69%) and 18% (95% CI:5-40%) respectively. Median progression-free survival was 3.0 months (range 1-9 months). Median overall survival was 16.4 months (range 1.5-51.7 months). Assessment of toxicity by patient showed 58% demonstrating grade 3/4 neutropenia with the vast majority being uncomplicated. No severe non-hematological toxicity was observed. CONCLUSION Administration of topotecan and navelbine is feasible with demonstrable activity and tolerable toxicity. This regimen may be considered especially in platinum-sensitive patients if a non-platinum based doublet is desired.

Abstract
Purpose We aimed at investigating the efficacy, tolerability, and quality of life (QOL) of gemcitabine (GEM) compared with pegylated liposomal doxorubicin (PLD) in the salvage treatment of recurrent ovarian cancer. Patients and Methods A phase III randomized multicenter trial was planned to compare GEM (1,000 mg/m2 on days 1, 8, and 15 every 28 days) with PLD (40 mg/m2 every 28 days) in ovarian cancer patients who experienced treatment failure with only one platinum/paclitaxel regimen and who experienced recurrence or progression within 12 months after completion of primary treatment. Results One hundred fifty-three patients were randomly assigned to PLD (n = 76) or GEM (n = 77). Treatment arms were well balanced for clinicopathologic characteristics. Grade 3 or 4 neutropenia was more frequent in GEM-treated patients versus PLD-treated patients (P = .007). Grade 3 or 4 palmar-plantar erythrodysesthesia was documented in a higher proportion of PLD patients (6%) versus GEM patients (0%; P = .061). The overall response rate was 16% in the PLD arm compared with 29% in the GEM arm (P = .056). No statistically significant difference in time to progression (TTP) curves according to treatment allocation was documented (P = .411). However, a trend for more favorable overall survival was documented in the PLD arm compared with the GEM arm, although the P value was of borderline statistical significance (P = .048). Statistically significantly higher global QOL scores were found in PLD-treated patients at the first and second postbaseline QOL assessments. Conclusion GEM does not provide an advantage compared with PLD in terms of TTP in ovarian cancer patients who experience recurrence within 12 months after primary treatment but should be considered in the spectrum of drugs to be possibly used in the salvage setting.

Abstract
BACKGROUND A prospective phase II study was conducted to evaluate the efficacy and toxicity of the combination docetaxel (Taxotere) (DTX) and oxaliplatin (OXA) in ovarian cancer patients recurring after a platinum-free interval (PFI) >12 months. PATIENTS AND METHODS DTX, 75 mg/m(2), was administered by 60 min i.v. infusion, followed by OXA, 100 mg/m(2), given by a 2 h i.v., on day 1 every 21 days. RESULTS From October 2003 to June 2006, 43 ovarian cancer patients were enrolled. Median PFI was 26 months. All patients were available for response evaluation: 17 complete responses and 12 partial responses were registered, for an overall response rate of 67.4%. The median response duration was 10 months. Stable disease was documented in 11 patients (median duration = 5.5 months). The median time to progression and overall survival were 14 and 28 months. A total of 259 courses were administered. Grade 3-4 leukopenia was documented in 32.5% of the patients, while no case of severe anemia and thrombocytopenia was observed. Grade 3-4 neurotoxicity and grade 2 alopecia were observed in 9.3% and 34.9% of cases, respectively. CONCLUSION DTX/OXA combination is an active regimen with a favorable toxicity profile, for treatment of recurrent platinum-sensitive ovarian cancer patients.

Abstract
INTRODUCTION Gemcitabine (2',2'-difluorodeoxycytidine) (GEM) has been demonstrated to be active in the salvage setting of ovarian cancer (OC) patients. CASE REPORT A 57-year-old woman, with a diagnosis of FIGO Stage IIIC clear cell OC, judged inoperable to optimal residual tumor, was administered neo-adjuvant chemotherapy with carboplatin/paclitaxel/topotecan, and cytoreduction. After 5 months the patient progressed, and pegylated liposomal doxorubicin was started with rapid progression. GEM (1,000 mg/m2, d1,8,15, q28) was then started, and a complete clinical response was documented after seven cycles of treatment, and was maintained for 9 months; at progression fourth line carboplatin was attempted but 1 month after the last course of carboplatin, progression occurred, and the patient was re-challenged with GEM obtaining a partial response, of 6 months duration. Currently, the patient is still under treatment, without any complaints relative to her quality of life/specific symptoms. CONCLUSION We described the case of a drug resistant clear cell ovarian cancer showing a selective susceptibility only to GEM at first administration and at re-challenge. Moreover, this case expressed a molecular profile very likely to support high tumour cell sensitivity to GEM.
