Purpose: We observed that the tumor microenvironment (TME) in metastatic epithelial ovarian cancer (EOC) and in other solid tumors can reprogram normal neutrophils to acquire a complement-dependent suppressor phenotype characterized by inhibition of stimulated T cell activation. This study aims to evaluate whether serum markers of neutrophil activation and complement at diagnosis of EOC would be associated with clinical outcomes.
Experimental Design: We conducted a two-center prospective study of patients with newly diagnosed EOC (N = 188).
Article Synopsis
- Recurrent ovarian cancer patients, especially those resistant to platinum treatments, currently have few effective curative options, prompting a phase 2 clinical trial (NCT02853318) that combined pembrolizumab with bevacizumab and oral cyclophosphamide.
- The trial included 40 patients and showed promising results, with a median progression-free survival of 10.2 months, a 47.5% objective response rate, and 30% of patients achieving stable disease for over a year while maintaining a good quality of life.
- Comprehensive analysis revealed that increased T and B cell count and specific microbiome patterns correlated with strong clinical responses, suggesting that understanding the immune environment and gut microbiome could enhance future cancer treatment
Article Synopsis
- The study aimed to understand how inflammation within the perivascular tumor microenvironment (TME) influences the movement and effectiveness of T-cells in fighting ovarian tumors.
- Researchers found that moderate inflammation, triggered by a specialized oncolytic virus, led to better T-cell activity and less immune suppression compared to weak or strong inflammation.
- The results suggest that combining treatments could help T-cells better navigate the TME and improve their efficiency in combating cancer.
To identify credible causal risk variants (CCVs) associated with different histotypes of epithelial ovarian cancer (EOC), we performed genome-wide association analysis for 470,825 genotyped and 10,163,797 imputed SNPs in 25,981 EOC cases and 105,724 controls of European origin. We identified five histotype-specific EOC risk regions (p value <5 × 10) and confirmed previously reported associations for 27 risk regions. Conditional analyses identified an additional 11 signals independent of the primary signal at six risk regions (p value <10).

The aim of this study was to collate exome sequencing data from multiple epithelial ovarian cancer case cohorts and controls in order to systematically evaluate the role of coding, loss-of-function variants across the genome in epithelial ovarian cancer risk. We assembled exome data for a total of 2,573 non-mucinous cases (1,876 high-grade serous and 697 non-high grade serous) and 13,925 controls.
