Germline BRCA mutation carriers are more likely to undergo cytoreductive surgery for relapsed, platinum sensitive, ovarian cancer. Gynecol Oncol 2022; 167:256-260. [PMID: 36154762 DOI: 10.1016/j.ygyno.2022.08.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 08/07/2022] [Accepted: 08/25/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVE BRCA mutations have been associated with improved outcomes in ovarian cancer patients. This study's objective was to compare the secondary cytoreduction surgery (SCS) rates among ovarian cancer patients by BRCA mutation status. METHODS The study was retrospective and included platinum sensitive recurrent high grade serous ovarian cancer patients from one Canadian center and two Israeli centers from January 1999 to December 2018. Demographic and genetic data, tumor characteristics, patterns of recurrence and surgical and medical treatments were obtained from electronic charts. Patients were grouped according to BRCA mutation status. Logistic regression analyses were used to explore potential prognostic factors of secondary cytoreduction. RESULTS 147 patients were enrolled, including 97 from Canada and 50 from Israel. Forty-seven patients (32%) had a BRCA mutation, including 39 (26.5%) germline mutations and 8 (5.5%) somatic mutations. Thirty-one patients (21.1%) underwent SCS. The rate of SCS was 33.3% among the germline BRCA mutation carriers and 15.7% among patients without germline BRCA mutation (p = 0.026). Predictors of secondary cytoreduction included germline BRCA mutation (OR = 2.5, p = 0.03), time to recurrence (OR = 1.004 per month, p < 0.001), absence of lymphatic recurrence (OR = 3.08, p = 0.013), three or fewer lesions at recurrence (OR = 36.74, p < 0.001) and absence of ascites (OR = 9.1, p = 0.034). After adjusting for the number of lesions at recurrence, no other variable remained a significant predictor. CONCLUSION Germline BRCA mutation carriers are more likely to undergo secondary cytoreduction. This may be mediated in part by lower volume disease at recurrence. This observation should be considered when planning surveillance for these patients after first-line treatment.

Abstract
Epigenetic dysregulation plays a crucial role in the development and progression of ovarian cancer. Since the first experiment conducted on resistant ovarian cancer cells using demethylating drugs, multiple clinical trials have revealed that epigenetic targeted drugs combined with chemotherapy, molecular-targeted drugs, or even immunotherapy could enhance tumor sensitivity and reverse acquired resistances. Here, we summarized the combination strategies of epigenetic targeted drugs with other treatment strategies of ovarian cancer and discussed the principles of combination therapy. Finally, we enumerated several reasonable clinical trial designs as well as future drug development strategies, which may provide promising ideas for the application of epigenetic drugs to ovarian cancer.

Front Oncol 2022; 12:1037796. [PMID: 36936273 PMCID: PMC10016260 DOI: 10.3389/fonc.2022.1037796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 12/28/2022] [Indexed: 02/22/2023] Open
Abstract
Background Despite prior attempts to evaluate the effects of sarcopenia on survival among patients with gynecologic cancer, the results of these studies have not been consistent. The present study evaluated the association between sarcopenia and survival among patients with gynecologic cancer by aggregating multiple studies. Methods We performed a literature search using computerized databases and identified additional studies included in the bibliographies of retrieved articles. The quality of each study was evaluated using the Newcastle-Ottawa Scale, and meta-analyses were performed to evaluate overall survival (OS) and progression-free survival (PFS). We constructed a forest plot for each outcome and assessed publication bias using Begg's test. Heterogeneity was assessed using I2 statistics. Results From the 5,933 initially identified articles, 16 studies describing 2,031 participants with a mean age of 60.34 years were included in the meta-analysis. We found that compared with patients with gynecologic cancer but without sarcopenia, patients with sarcopenia had worse OS, with a pooled hazard ratio (HR) of 2.61 (95% confidence interval [CI]:1.52-4.46), and worse PFS (HR: 1.37, 95% CI: 1.09-1.73). The quality of studies was generally good, and no publication bias was detected among studies for either OS or PFS. Although 4 of 12 studies were of fair quality, we conducted a sensitivity analysis excluding studies or fair quality and obtained similar results. Conclusions These meta-analysis results suggest that sarcopenia is associated with worse OS and PFS among patients with gynecologic cancer. The use of different case definitions appeared to be a major source of heterogeneity among the studies. Further studies remain necessary to confirm our findings, especially those examining OS and PFS, because publication bias was identified.

Oncologist 2019; 24:e1471-e1475. [PMID: 31346131 PMCID: PMC6975939 DOI: 10.1634/theoncologist.2019-0272] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2019] [Accepted: 07/08/2019] [Indexed: 01/14/2023] Open
Abstract
OBJECTIVE BRCA mutations are the most frequent mutations causing homologous recombination defects in epithelial ovarian cancers (EOC). Germline mutation carriers are heterozygous for the mutation and harbor one defective allele in all cells. This has been hypothesized to cause increased susceptibility to DNA damage in healthy cells as well as neoplastic ones. Our objective was to assess chemotherapy-associated toxicities in patients with epithelial ovarian cancer with and without a germline BRCA mutation. MATEIALS AND METHODS A retrospective cohort study of patients with EOC receiving first-line platinum-based chemotherapy at a single center between 2006 and 2016. Indices of chemotoxicity, including blood counts, transfusion requirements, granulocyte colony-stimulating factor (gCSF) prescriptions, episodes of febrile neutropenia, and treatment delays were compared for BRCA mutation carriers and noncarriers. RESULTS A total of 90 women met the inclusion criteria, including 31 BRCA mutation carriers (34%) and 59 noncarriers (66%). Mean hemoglobin, neutrophil count, and platelet counts during treatment were comparable for the two patient groups. There was a trend toward a higher frequency of hematological events in BRCA mutation carriers (neutropenia <1500 per mL: 6% vs. 0%, p = .12; thrombocytopenia <100,000 per mL: 23% vs. 9%, p = .07), but these differences were not statistically significant. Similarly, no significant differences were found in surrogates of bone marrow toxicity such as blood transfusions, use of gCSF, episodes of febrile neutropenia, or treatment delays. CONCLUSION BRCA mutation carriers and noncarriers receiving first-line platinum-based chemotherapy for EOC have similar hematologic toxicity profiles. Clinicians treating these patients can be reassured that chemotherapy dosing or schedule do not require adjustment in patients carrying BRCA mutations. IMPLICATIONS FOR PRACTICE Patients with ovarian cancer carrying BRCA mutations are more likely to have serous tumors and present with higher CA125 levels. Germline BRCA mutation status is not associated with increased frequency of adverse hematologic events among patients with ovarian cancer being treated with first-line platinum-based chemotherapy. Germline BRCA mutations are also not associated with more treatment delays or a lower number of courses completed in this patient population. These findings should reassure practitioners engaged in care for patients with ovarian cancer that BRCA mutation status most likely will not affect chemotherapy dosing or schedule.

Abstract
Tumor necrosis factor-α-induced protein 8 (TNFAIP8) is an independent prognostic factor for cancer-specific and disease-free survival in patients with epithelial ovarian cancer (EOC). However, the exact mechanism of the biological role of TNFAIP8 in EOC remains unclear. In the present study, a siRNA specifically targeting TNFAIP8 was prepared to knock down TNFAIP8 in EOC cells. Cell growth, colony formation, apoptosis, and cell cycle distribution in TNFAIP8-deficient EOC cells were determined. In addition, the underlying molecular mechanisms were investigated by western blot analysis and reverse transcription quantitative polymerase chain reaction assays. It was demonstrated that the knockdown of TNFAIP8 inhibited EOC cell growth and colony formation, along with increased levels of apoptosis and cell cycle arrest. The results of the western blot analysis suggested that TNFAIP8 inhibited the expression of phosphorylated yes-associated protein 1 (YAP) while promoting total and nuclear YAP expression, followed by the regulation of apoptosis and cell cycle checkpoint protein expression in EOC. Overexpression of YAP in EOC cells efficiently attenuated cell growth inhibition in TNFAIP8-deficient EOC cells. In addition, knockdown of TNFAIP8 significantly impaired EOC tumor growth in vivo. Collectively, the data from the present study suggested that TNFAIP8 is an oncogene and a novel therapeutic target for EOC.

Abstract
The insulin-like growth factor (IGF) system comprises multiple growth factor receptors, including insulin-like growth factor 1 receptor (IGF-1R), insulin receptor (IR) -A and -B. These receptors are activated upon binding to their respective growth factor ligands, IGF-I, IGF-II and insulin, and play an important role in development, maintenance, progression, survival and chemotherapeutic response of ovarian cancer. In many pre-clinical studies anti-IGF-1R/IR targeted strategies proved effective in reducing growth of ovarian cancer models. In addition, anti-IGF-1R targeted strategies potentiated the efficacy of platinum based chemotherapy. Despite the vast amount of encouraging and promising pre-clinical data, anti-IGF-1R/IR targeted strategies lacked efficacy in the clinic. The question is whether targeting the IGF-1R/IR signaling pathway still holds therapeutic potential. In this review we address the complexity of the IGF-1R/IR signaling pathway, including receptor heterodimerization within and outside the IGF system and downstream signaling. Further, we discuss the implications of this complexity on current targeted strategies and indicate therapeutic opportunities for successful targeting of the IGF-1R/IR signaling pathway in ovarian cancer. Multiple-targeted approaches circumventing bidirectional receptor tyrosine kinase (RTK) compensation and prevention of system rewiring are expected to have more therapeutic potential.

Abstract
The standard approach to treating patients with advanced epithelial ovarian cancer (EOC) after primary debulking surgery remains taxane and platinum-based chemotherapy. Despite treatment with this strategy, the vast majority of patients relapse and develop drug-resistant metastatic disease that may be driven by cancer stem cells (CSCs) or cancer initiating cells (CICs). Oncolytic viruses circumvent typical drug-resistance mechanisms, therefore they may provide a safe and effective alternative treatment for chemotherapy-resistant CSCs/CICs. Among oncolytic viruses vesicular stomatitis virus (VSV) has demonstrated oncolysis and preferential replication in cancer cells. In this review, we summarize the recent findings regarding existing knowledge on biology of the ovarian cancer and the role of ovarian CSCs (OCSCs) in tumor dissemination and chemoresistance. In addition we also present an overview of recent advances in ovarian cancer therapies with oncolytic viruses (OV). We focus particularly on key genetic or immune response pathways involved in tumorigenesis in ovarian cancer which facilitate oncolytic activity of vesicular stomatitis virus (VSV). We highlight the prospects of targeting OCSCs with VSV. The importance of testing an emerging ovarian cancer animal models and ovarian cancer cell culture conditions influencing oncolytic efficacy of VSV is also addressed.

Abstract
In ovarian cancer (OVCA), treatment failure due to chemo-resistance is a serious challenge. It is therefore critical to identify new therapies that are effective against resistant tumors and have reduced side effects. We recently identified 4-H-chromenes as tubulin depolymerizing agents that bind to colchicine site of beta-tubulin. Here, we screened a chemical library of substituted 4-H-chromenes and identified SP-6-27 to exhibit most potent anti-proliferative activity towards a panel of human cisplatin sensitive and resistant OVCA cell lines with 50% inhibitory concentration (IC50; mean ± SD) ranging from 0.10 ± 0.01 to 0.84 ± 0.20 μM. SP-6-27 exhibited minimum cytotoxicity to normal ovarian epithelia. A pronounced decrease in microtubule density as well as G2/M cell cycle arrest was observed in SP-6-27 treated cisplatin sensitive/resistant OVCA cells. The molecular mechanism of SP-6-27 induced cell death revealed modulation in cell-cycle regulation by upregulation of growth arrest and DNA damage inducible alpha transcripts (GADD45). An enhanced intrinsic apoptosis was observed in OVCA cells through upregulation of Bax, Apaf-1, caspase-6, -9, and caspase-3. In vitro wound healing assay revealed reduced OVCA cell migration upon SP-6-27 treatment. Additionally, SP-6-27 and cisplatin combinatorial treatment showed enhanced cytotoxicity in chemo-sensitive/resistant OVCA cells. Besides effect on cancer cells, SP-6-27 further restrained angiogenesis by inhibiting capillary tube formation by human umbilical vein endothelial cells (HUVEC). Together, these findings show that the chromene analog SP-6-27 is a novel chemotherapeutic agent that offers important advantages for the treatment of ovarian cancer.

Abstract
Lysosome-associated membrane protein 3 belongs to the lysosome-associated membrane glycoprotein family, which is associated with lymph node, metastasis, poor overall survival, and resistance to chemotherapy and radiotherapy. Epithelial ovarian cancer is one of the most deadly global female gynecologic malignant tumors. Its clinical outcome is poor and most epithelial ovarian cancer patients tend to relapse because of drug resistance. However, lysosome-associated membrane protein 3 expression in epithelial ovarian cancer and its relationship between clinicopathologic factors remain poorly understood. To clarify the prognostic implications of lysosome-associated membrane protein 3 in epithelial ovarian cancer, we analyzed both messenger RNA and protein levels of lysosome-associated membrane protein 3 in ovarian carcinomas. Polymerase chain reaction results showed higher expression of lysosome-associated membrane protein 3 messenger RNA in epithelial ovarian cancer than in noncancerous tissues. Immunohistochemical results showed that high lysosome-associated membrane protein 3 cytoplasmic expression was significantly related to tumor grade ( p = 0.038), lymph node metastasis ( p = 0.049), metastasis ( p < 0.001), level of CA125 ( p = 0.030), and International Federation of Gynecology and Obstetrics (FIGO) ( p < 0.001). High lysosome-associated membrane protein 3 nuclear expression was significantly associated with tumor grade ( p = 0.046), tumor single or double (representative whether the tumor involving one or both ovaries) ( p = 0.016), metastasis ( p < 0.001), and FIGO stage ( p < 0.001). Survival analysis indicated that high lysosome-associated membrane protein 3 cytoplasmic expression (hazard ratio: 4.632, 95% confidence interval: 2.421-8.864; p < 0.001), patients' age (hazard ratio: 1.729, 95% confidence interval: 1.027-2.911; p = 0.039), and FIGO stage (hazard ratio: 2.049, 95% confidence interval: 1.113-3.774; p = 0.021) were significantly correlated with poor survival outcome of epithelial ovarian cancer patients.
