Ovarian cancer remains the gynecological cancer with the highest mortality rate. In our study, we compare a number of proteins from different effector pathways to assess their usefulness in the diagnosis of ovarian cancer. The tissue expression of the tested proteins was assessed by two methods: qRT-PCR and an immunohistochemical analysis. A significantly higher level of mRNA expression was found in the ovarian cancer group for and ( = 0.004 and = 0.003, respectively). There was no statistical significance in the expression of mRNA for , and there was borderline statistical significance for between the groups of ovarian cancer patients and other subgroups of patients with simple cysts and healthy ovarian tissue ( = 0.726 and = 0.046, respectively). Significantly higher levels of transferrin receptor (), , and gene expression were found in the ovarian cancer group compared to the control group for , and TEAD4 showed strong nuclear and cytoplasmic staining in ovarian carcinoma and weak staining in non-carcinoma ovarian samples, ADH1A1 showed strong staining in the cytoplasm of carcinoma sections and a weak positive reaction in the non-carcinoma section, H2A.X showed strong positive nuclear staining in carcinoma sections and moderate positive staining in non-carcinoma samples, and CD71 showed moderate positive staining in carcinoma and non-carcinoma samples. YAP, TEAD4, and ADH1A proteins appear to be promising biomarkers in the diagnosis of ovarian cancer.

Torsion and ruptured ovarian cystadenocarcinoma with internal bleeding complicated with retroperitoneal hematoma after tumor transection: A case report.

Department of Obstetrics and Gynecology, Minimally Invasive Gynecology Surgery Center, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien, Taiwan.
Rationale: Ovarian tumor torsion is a critical gynecological emergency, predominantly affecting women of reproductive age, with benign teratomas being the most common culprits. In contrast, malignant ovarian tumors, such as mucinous cystadenocarcinoma, infrequently present with torsion due to their invasive and angiogenic characteristics. The occurrence of torsion in malignant tumors complicates diagnosis and management, particularly when associated with complications like congestion, infarction, and internal bleeding.

Solitary axillary lymph node metastasis from ovarian cancer is rare. A 74-year-old woman who had undergone hysterectomy and bilateral salpingo-oophorectomy for ovarian cancer 2 years ago presented to our hospital with enlarged axillary lymph node. 18F-FDG PET/CT revealed left axillary lymphadenopathy with an SUVmax of 8.

The first-in-human, Phase 1 Study 101 showed antitumor activity and a tolerable safety profile of farletuzumab ecteribulin in Japanese patients with platinum-resistant ovarian and non-small cell lung cancer. A pharmacometric assessment evaluated farletuzumab ecteribulin pharmacokinetics and exposure-response (E-R) relationships for efficacy and safety to support dose optimization. Patients received 0.

Aim: To examine the prognostic impact of textbook oncologic outcome (TOO) in patients with advanced ovarian cancer undergoing primary chemotherapy, along with identifying the risk factors for TOO failure.
Methods: Patients who underwent neoadjuvant chemotherapy followed by interval debulking surgery for advanced ovarian cancer at a tertiary center between 2014 and 2019 were retrospectively reviewed. TOO was defined as complete cytoreduction, no severe complications, no prolonged hospital stay, no readmission, no delayed initiation of adjuvant chemotherapy, and no 90-day mortality.
Niraparib Maintenance Therapy in Patients with Platinum-Sensitive Recurrent Ovarian Cancer: Real-World Experience at Hospitals in Spain.
Target Oncol

Pharmacy Service, H. Móstoles, Madrid, Spain.
Background: The reported benefit of poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance in patients with newly diagnosed and platinum (Pt)-sensitive recurrent ovarian cancer (OC) included in randomized clinical trials needs to be corroborated in a less selected population.
Objective: The aim is to increase the evidence on niraparib in a real-world setting.
Methods: This is a retrospective observational study including women with platinum-sensitive relapsed high-grade serous OC who started niraparib maintenance between August 2019 (marketing data, Spain) and May 2022.
