A Clinical and Immunopathological Analysis of Carcinoma of the Ovary with an Emphasis on Post-chemotherapy Histopathologic Changes. Indian J Surg Oncol 2023; 14:545-552. [PMID: 37900629 PMCID: PMC10611652 DOI: 10.1007/s13193-023-01756-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 04/25/2023] [Indexed: 10/31/2023] Open
Abstract
Ovarian cancers are a heterogeneous group of malignant tumors that differ with respect to pathogenesis, morphology, molecular features, and behavior. Pathologists and clinicians need to be aware of the advances in diagnosis and the changes which occur after chemotherapy to offer the optimal treatment to each patient. The present work aims to study the morphologic and immunohistochemical (IHC) profile of primary ovarian cancers with an assessment of post-chemotherapy changes. A total of 51 cases were included in the study from June 2017 to June 2019 (prospective and retrospective). The demographic and clinical details of the patients were collected. The gross and microscopic features of the tumors were studied, and the post-chemotherapy changes were evaluated. A chi-square test was used to determine the association of tumor morphology, the chemotherapy response score (CRS), and stage of the tumor with survival (PFS and OS). The mean patient age was 47.5 years, and high-grade serous carcinoma (66.6%) (HGSC) was the most common subtype followed by mucinous carcinoma and endometrioid carcinoma. Immunohistochemical analysis with WT1 and p53 helped in the diagnosis of HGSC. The CRS was 1 and 2 in most of the cases. The follow-up for patients of HGSC was available for a period of 1-27 months with a mean survival for primary resection of 24 months and for post-NACT resection was 17 months. This difference was not statistically significant (p = 0.38). High-grade serous carcinoma was the most common ovarian cancer in our series, and immunohistochemistry played an important role in the diagnosis. We could not demonstrate any survival benefit of preoperative chemotherapy in our series.

New Insights into Ferroptosis Initiating Therapies (FIT) by Targeting the Rewired Lipid Metabolism in Ovarian Cancer Peritoneal Metastases. Int J Mol Sci 2022; 23:ijms232315263. [PMID: 36499591 PMCID: PMC9737695 DOI: 10.3390/ijms232315263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 11/04/2022] [Accepted: 11/24/2022] [Indexed: 12/11/2022] Open
Abstract
Ovarian cancer is one of the most lethal gynecological cancers worldwide. The poor prognosis of this malignancy is substantially attributed to the inadequate symptomatic biomarkers for early diagnosis and effective remedies to cure the disease against chemoresistance and metastasis. Ovarian cancer metastasis is often relatively passive, and the single clusters of ovarian cancer cells detached from the primary ovarian tumor are transcoelomic spread by the peritoneal fluid throughout the peritoneum cavity and omentum. Our earlier studies revealed that lipid-enriched ascitic/omental microenvironment enforced metastatic ovarian cancer cells to undertake metabolic reprogramming and utilize free fatty acids as the main energy source for tumor progression and aggression. Intriguingly, cell susceptibility to ferroptosis has been tightly correlated with the dysregulated fatty acid metabolism (FAM), and enhanced iron uptake as the prominent features of ferroptosis are attributed to the strengthened lipid peroxidation and aberrant iron accumulation, suggesting that ferroptosis induction is a targetable vulnerability to prevent cancer metastasis. Therefore, the standpoints about tackling altered FAM in combination with ferroptosis initiation as a dual-targeted therapy against advanced ovarian cancer were highlighted herein. Furthermore, a discussion on the prospect and challenge of inducing ferroptosis as an innovative therapeutic approach for reversing remedial resistance in cancer interventions was included. It is hoped this proof-of-concept review will indicate appropriate directions for speeding up the translational application of ferroptosis-inducing compounds (FINs) to improve the efficacy of ovarian cancer treatment.

Abstract
BACKGROUND Remdesivir is an anti-viral drug that inhibits RNA polymerase. In 2020, remdesivir was recognized as the most promising therapeutic agents against coronavirus disease 2019 (COVID-19). However, the effects of remdesivir on cancers have hardly been studied. PURPOSE Here, we reported that the anti-carcinogenic effect of remdesivir on SKOV3 cells, one of human ovarian cancer cell lines. RESEARCH DESIGN We anlalyzed the anti-carcarcinogenic effect of remdesivir in SKOV3 cells by performing in vitro cell assay and western blotting. RESULTS WST-1 showed that remdesivir decreased cell viability in SKOV3 cells. Experiments conducted by Muse Cell Analyzer showed that remdesivir-induced apoptosis in SKOV3 cells. We found that the expression level of FOXO3, Bax, and Bim increased, whereas Bcl-2, caspase-3, and caspase-7 decreased by remdesivir in SKOV3 cells. Furthermore, we observed that intracellular reactive oxygen species (ROS) level increased after treatment of remdesivir in SKOV3 cells. Interestingly, cytotoxicity of remdesivir decreased after treatment of N-Acetylcysteine. CONCLUSION Taken together, our results demonstrated that remdesivir has an anti-carcinogenic effect on SKOV3 cells vis up-regulation of reactive oxygen species, which suggests that remdesivir could be a promising reagent for treatment of ovarian cancer.

Abstract
Ovarian cancer (OC) is one of the most common malignant tumors in women. OC is associated with the activation of oncogenes, the inactivation of tumor suppressor genes, and the activation of abnormal cell signaling pathways. Moreover, epigenetic processes have been found to play an important role in OC tumorigenesis. Epigenetic processes do not change DNA sequences but regulate gene expression through DNA methylation, histone modification, and non-coding RNA. This review comprehensively considers the importance of epigenetics in OC, with a focus on microRNA and long non-coding RNA. These types of RNA are promising molecular markers and therapeutic targets that may support precision medicine in OC. DNA methylation inhibitors and histone deacetylase inhibitors may be useful for such targeting, with a possible novel approach combining these two therapies. Currently, the clinical application of such epigenetic approaches is limited by multiple obstacles, including the heterogeneity of OC, insufficient sample sizes in reported studies, and non-optimized methods for detecting potential tumor markers. Nonetheless, the application of epigenetic approaches to OC patient diagnosis, treatment, and prognosis is a promising area for future clinical investigation.

Abstract
BACKGROUND Epithelial ovarian cancer (EOC) is a lethal disease due to late diagnosis and lack of effective screening methods. MicroRNA (miR/miRNA) plays an important role in ovarian carcinogenesis and may serve as a non-invasive biomarker for EOC. This study aimed to assess miR-141 expression in the blood plasma of patients with EOC and healthy subjects and determine its association with the clinical stage of EOC. METHODS This cross-sectional study used blood plasma from 30 newly diagnosed untreated patients with EOC and 25 healthy subjects. The mean age was 47.73 (SD = 10.29) years for EOC and 44.48 (SD = 16.14) years for healthy subject. The total RNA was isolated from blood plasma and reversed transcribed to obtain cDNA. The expression of miR-141 was measured by real-time quantitative polymerase chain reaction (qRT-PCR), and calculated using 2-ΔΔCt methods. The data were analysed using Mann-Whitney test. RESULTS The expression of miR-141 was upregulated 8.41 fold in the blood plasma of EOC patients compared to healthy controls (P < 0.001). Expression of miR-141 in the advanced stage was upregulated 4.2 fold compared to the early stage (P < 0.001). CONCLUSION The miR-141 was upregulated in the blood plasma of EOC and associated with an advanced stage of disease, suggesting it has potential as a biomarker for EOC detection.

Abstract
Ovarian cancer (OC) is one of the most dangerous gynecological diseases and greatly increases the death risk worldwide. The heterogeneity of the ovarian tumors among patients and the lack of sufficient therapies for these tumors make the selection of the appropriate treatment a hard challenge. Understanding the mechanisms leading to OC becomes an urgent need in order to find out better therapeutic strategies. In this study, we have identified a point mutation (L449S) in the regulatory subunit of PI3K in an OC Lebanese patient. This genomic alteration had not been previously reported in OC and could plausibly enhance the PIK3CA amplification effect in strengthening AKT/mTOR pathway activity and leading to tumorigenesis.

Abstract
Background Clinical variation in ovarian cancer care has been reported internationally. Using Wennberg’s classification of clinical variation as effective care we can conceptualise variation through deviation from clinical guidelines. The aim of this review was to address knowledge gaps in the effectiveness of attempts to reduce unwarranted clinical variation through addressing the following questions: What is the evidence of guideline adherence in ovarian cancer and its deviation?; what are the key factors associated with variation in guideline adherence in ovarian cancer care?; and what quality improvement approaches have been used and what is the evidence of their effectiveness in enhancing guideline adherence in ovarian cancer care?. Methods Keywords and synonyms for the major concepts of ovarian cancer, guideline adherence and safety were developed and combined to form the search strategy. Systematic searches of four electronic databases were undertaken of publications from January 2007 to November 2018. Retrieved articles were assessed against the eligibility criteria to determine those for inclusion. Results Thirty-two papers were included in the review with three broad groupings identified: adherence to and deviation from guidelines (either local, national or international guidelines); factors impacting guidelines adherence; and quality improvement approaches. Conclusions Unwarranted clinical variation may be used as a marker for the effectiveness of a health system, based on the outcome of this systematic review. This review found that the implementation of quality indicators through a formal quality improvement program lead to improvements in guideline adherent care. Further research on outcomes of implementing quality improvement programs in ovarian cancer care will improve the ability to implement centralised care and further identify factors that to improve outcomes in ovarian cancer care.

Abstract
Ovarian cancer (OC) is a relatively fatal female reproductive malignancy. Since the underlying causes are uncertain, it brings us to believe that both genetic and external factors contribute toward development of this lethal disorder. Exposure to endocrine-disrupting chemicals (EDCs) in the form of occupational usage of pesticides, fungicides, herbicides, plasticizers, cosmetics, and so on is potentially carcinogenic and their ability to cause epigenetic modifications has led us to hypothesize that they may play a catalytic role in OC progression. In response to synthetic chemicals, animal models have demonstrated disturbances in the development of ovaries and steroid hormonal levels but in humans, more research is required. The present review is an attempt to address the impact of EDCs on the hormonal system and gene methylation levels that may lead to malfunctioning of the ovaries which may consequently develop in the form of cancer. It can be concluded that endocrine disruptors do have a potential carcinogenicity and their high proportions in human body may cause epigenetic modifications, prompting ovarian surface epithelium to grow in an abnormal manner.
