The aim of this study was to assess the clinical evidence for platinum-Taxol non-cross-resistance in patients with epithelial ovarian cancer. Unlike other studies, only patients who had demonstrably progressive disease on platinum therapy were analysed. Patients received 135-200 mg m-2 of Taxol over 3 or 24 h and all patients were assessed for response by computerised axial tomography. The overall response rate was 22.2% (8/36 patients, 95% CI 10-39%). Only patients who received > or = 175 mg m-2 of Taxol responded (26.7%; 8/30 patients, 95% CI 12-46%). No complete responses were seen and the duration of response was short, median 7 months (range 5-9+). Response was associated with a short treatment-free interval (P = 0.02); only those who were treated immediately after they had progressed on their previous platinum therapy responded. Response duration was associated with a good performance status (P < 0.05). Platinum and Taxol are non-cross-resistant in a proportion of patients and therefore patients who are resistant to platinum compounds may benefit from Taxol although the duration of any response is short. These data support current strategies that involve combining Taxol with platinum compounds as first-line therapy in advanced epithelial ovarian cancer.

Glycosylation changes of circulating proteins carrying the CA19-9 antigen may offer new targets for detection methods to be explored for the diagnosis of epithelial ovarian cancer (EOC). Search for assay designs for targets initially captured by a CA19-9 antigen reactive antibody from human body fluids by probing with fluorescent nanoparticles coated with lectins or antibodies to known EOC associated proteins. CA19-9 antigens were immobilized from ascites fluids, ovarian cyst fluids or serum samples using monoclonal antibody C192 followed by probing of carrier proteins using anti-MUC16, anti-MUC1 and, anti STn antibodies and seven lectins, all separately coated on nanoparticles.

Currently, Ovarian Cancer (OC) is the most lethal gynecological malignancy. In most patients, it progresses without clinical signs or symptoms, leading to a late diagnosis when it has already spread in the peritoneal cavity as peritoneal carcinomatosis (PC). To date, OC PC management is based on cytoreductive surgery to remove the macroscopic disease, followed by chemotherapy.

Epithelial ovarian cancer (EOC) remains a leading cause of gynecologic cancer mortality. Despite advances in treatment, metastatic progression and resistance to standard therapies significantly worsen patient outcomes. Epithelial-mesenchymal transition (EMT) is a critical process in metastasis, enabling cancer cells to gain invasive and migratory capabilities, often driven by changing miRNA expression involved in the regulation of pathological processes like drug resistance.

Onvansertib and Navitoclax Combination as a New Therapeutic Option for Mucinous Ovarian Carcinoma.

Int J Mol Sci

Laboratory of Gynecological Preclinical Oncology, Department of Experimental Oncology, Istituto di Ricerche Farmacologiche Mario Negri IRCCS, 20156 Milan, Italy.

Mucinous epithelial ovarian cancer (mEOC) is a rare subtype of epithelial ovarian cancer, characterized by poor responses to standard platinum-based chemotherapy. Polo-like kinase 1 (PLK1) is a key regulator of mitosis and cell cycle progression and its inhibition has been recently identified as a target in mEOC. In this study, we aimed to identify further therapeutic targets in mEOC using a CRISPR/Cas9 library targeting 3015 genes, with and without treatment with onvansertib, a PLK1 inhibitor.
