Exploring the Clinical Impact of Predictive Biomarkers in Serous Ovarian Carcinomas.

CONCLUSION: In the last decade, promising biomarkers have been validated and lead to new therapeutic strategies with PARP inhibitors, immunotherapy and anti-angiogenic agents. Biomarkers such as BRCA, homologus recombination defect (HRD), immuno-markers (CD8, PD-1, PDL-1), KRAS and PR, are now used in clinical trials. Other: Assessment of genetic variants will soon represent the standard-of-care in gynecological cancers, not only to diagnose the disease but also to assist the prediction of clinical behavior of tumors and support personalized medicine to match patients with appropriate targeted therapies, improving treatment efficacy and quality of life for patients.

sen K Abstract Introduction: The aim of the present study was to investigate the prognostic impact of intratumoral cytotoxic T cells, Natural Killer (NK) cells, neutrophils and PD-L1 expression in patients with epithelial ovarian cancer.Methods: All patients diagnosed with high-grade serous carcinoma (HGSC) in Denmark in 2005 were included in the study. Immunohistochemical staining for PD-L1, CD8, CD66b and CD57 was performed on tumor tissue from 283 patients. Cell densities were analyzed using a digital image analysis method. The primary endpoint was overall survival (OS).Results: The median OS for HGSC patients ...

Abstract Ovarian cancer (OvCa) remains the most common cause of death from gynecological malignancies. Genetically engineered mouse models have been used to study initiation, origin, progression and/or mechanisms of OvCa. Based on the clinical features of OvCa, we examined a quadruple combination of pathway perturbations including PTEN, TRP53, RB1, and/or CDH1. To characterize the cancer-promoting events in the ovarian surface epithelium (OSE), Amhr2cre/+ mice were used to ablate floxed alleles of Pten, Trp53 and Cdh1, which were crossed with TgK19GT121 mice to inactivate RB1 in KRT19 expressing cells. Inactivatio...

Abstract High-grade serous ovarian carcinoma (HGSOC) is the most lethal gynecologic cancer. Emerging evidence suggests that tumor-associated macrophages (TAMs) play an immunosuppressive role in the tumor microenvironment and promote tumor growth, angiogenesis, and metastasis in ovarian cancer. Therefore, targeting TAMs in patients with ovarian cancer is an appealing strategy; however, all trials to date have failed. To improve the efficacy of this approach, we sought to elucidate the underlying mechanisms of the role of TAMs in ovarian cancer. We found that the developmental transcription factor GATA3 was highly e...

This tumor has been exensively investigated and sequenced but expression profiling data of normal fallopian tube epithelial cells is still rare. This project compares the miRNA profiles of high grade serous papillary ovarian tumors (FFPE and fresh frozen) to that of normal unmatched epithelial cells from resected fallopian tubes.

Abstract Intercellular cell adhesion molecule-1 (ICAM-1), an important adhesion molecule in the immunoglobulin superfamily, is expressed on many cell types. Recent studies have identified ICAM-1 as a potential oncogene that promotes the development of epithelial ovarian cancer (EOC); it was also found to be associated with poor survival. However, the clinical significance of its expression in high-grade serous ovarian carcinoma (HGSOC) is unclear. Thus, this study aimed to investigate the significance of ICAM-1 expression in HGSOC. Data on ICAM1 expression and mutations in serous ovarian carcinoma (SOC) were obtai...

Brain metastasis is a rare and generally late manifestation of an advanced-stage, high-grade serous ovarian carcinoma. Nowadays, the improved control of intra-abdominal disease by surgery and platinum-based chemotherapy results in a longer survival, allowing distant metastasis to implant and grow in the brain parenchyma. Herein, we describe a unique case of a cerebellar metastasis from clear cell ovarian carcinoma that initially presented as a FIGO Stage IC cancer. Surprisingly, 6 mo after surgery, the patient was in good condition with complete disappearance of symptoms and no evidence of recurrence. This relativel...

In this study, data from the Surveillance, Epidemiology, and End Results (SEER) program were used to determine predictors of survival trajectories among women with epithelial ovarian cancer and across histotype (high-grade serous carcinoma (HGSC) and non-HGSC). METHODS: Data on 35,868 women diagnosed with epithelial ovarian cancer in 2004-2016 were extracted from SEER. Extended Cox proportional hazards regression was used to estimate overall and histotype-specific associations between patient and tumor characteristics and all-cause mortality within each survival time (t) interval (t
