An association between thrombocytosis and cancer progression and decreased survival has been observed for various forms of cancer. The aim of this study was to evaluate the impact of pre-treatment thrombocytosis on ovarian cancer survival. Medline, Scopus, Clinicaltrials.gov, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar were searched systematically for studies that compared survival outcomes of patients with ovarian cancer who had pre-treatment thrombocytosis with survival outcomes of patients with normal platelet counts. Fourteen articles were retrieved, with a total of 5414 patients with ovarian cancer. The methodological quality of included studies ranged between moderate and high. Patients with advanced stage disease were more likely to have pre-treatment thrombocytosis, and this was associated with lower rates of optimal debulking. Thrombocytosis was also associated with increased likelihood of recurrence of ovarian cancer [hazard ratio (HR) 2.01, 95 % confidence interval (CI) 1.34-3.01] and increased risk of death from ovarian cancer (HR 2.29, 95 % CI 1.35-3.90). The incidence of deep vein thrombosis was comparable in both groups (odds ratio 1.62, 95 % CI 0.48-5.46). Considering these findings, it is evident that pre-treatment thrombocytosis in patients with ovarian cancer is associated with increased risk of recurrence and death. Pre-treatment thrombocytosis is a potential sign of advanced stage disease, and may be predictive of suboptimal tumour debulking during surgery. Its association with other factors that affect survival, including platinum resistance and response to targeted therapy, remains poorly explored, although preliminary data suggest a potential correlation.

Introduction: Patients with advanced ovarian cancer often require radical cytoreductive surgery and chemotherapy, with or without targeted therapy. Return to intended oncological therapy after surgery is a crucial metric, as delay can worsen survival. The concept of return to intended oncological therapy is important because it highlights the need for not just successful surgical outcomes, but also the ability to continue with the comprehensive cancer treatment plan.

Forkhead box L2 (FOXL2) encodes a transcription factor essential for sex determination, and ovary development and maintenance. Mutations in this gene are implicated in syndromes involving premature ovarian failure and granulosa cell tumors (GCTs). This rare cancer accounts for less than 5% of diagnosed ovarian cancers and is causally associated with the FOXL2 c.

Epigenetic therapies facilitate transcription of immunogenic repetitive elements that cull cancer cells through 'viral mimicry' responses. Paradoxically, cancer-initiating events also facilitate transcription of repetitive elements. Contributions of repetitive element transcription towards cancer initiation, and the mechanisms by which cancer cells evade lethal viral mimicry responses during tumor initiation remain poorly understood.

PRIMA was restricted to patients at higher risk of progression (excluded stage III EOC with no visible residual disease [NVRD] after primary cytoreductive surgery [PCS]). This retrospective study evaluated the potential impact of excluding stage III EOC with NVRD from PRIMA by assessing real-world treatment outcomes following 1LM niraparib monotherapy in this patient population.

Background: Ovarian Cancer is one of the leading causes of cancer death among women worldwide and the therapeutic landscape to treat it is constantly evolving. One of the major points of decision for the treatment choice is the presence of some genomic alterations that could confer sensitivity to the new available therapies including inhibitors of poly (ADP-ribose) polymerase (PARPi) with BRCA1 and 2 genes playing the most important role.
Methods And Results: We performed the search for any somatic and/or germline alteration in patient's samples by next generation sequencing (NGS).
