Background: Young age has been reported to be a favorable prognostic factor in ovarian cancer. The aim of the present study was to investigate the characteristics of ovarian cancer presenting in patients aged < or =40 and assess the prognostic significance of young age.
Methods: Data from 591 consecutive ovarian cancer patients, including 37 subjects (6.3%) aged < or =40, who were treated postoperatively with platinum-based chemotherapy in our institution were retrospectively reviewed.
Results: In our series, age < or =40 did not show an independent association with overall (p = 0.542) or progression-free survival (p = 0.334). Nonetheless, it was correlated with low tumor grade (p = 0.009) and small volume of residual disease after primary surgery (p = 0.020), while there was a nonsignificant trend for correlation with performance status 0 (p = 0.052). Stratified analysis showed that age < or =40 was associated with improved overall survival in the subgroups of serous histology and stage IIC-IV disease; however, multivariate analyses failed to identify age as an independent predictor of survival within either subgroup (p = 0.079 and p = 0.585, respectively).
Conclusions: Age < or =40 was not an independent prognostic factor in our analysis. The survival advantage of young patients may be attributed to the association with low tumor grade, more complete surgical debulking and better performance status.

Risk Factors for Anastomotic Leakage: A Comprehensive Single-Center Analysis of Colorectal Anastomoses for Ovarian and Gastrointestinal Cancers.

Background: Anastomotic leakage (AL) is a major complication in colorectal surgery, particularly following rectal cancer surgery, necessitating effective prevention strategies. The increasing frequency of colorectal resections and anastomoses during cytoreductive surgery (CRS) for peritoneal carcinomatosis further complicates this issue owing to the diverse patient populations with varied tumor distributions and surgical complexities. This study aims to assess and compare AL incidence and associated risk factors across conventional colorectal cancer surgery (CRC), gastrointestinal CRS (GI-CRS), and ovarian CRS (OC-CRS), with a secondary focus on evaluating the role of protective ostomies.

Upregulation of Cyclin E1 and subsequent activation of CDK2 accelerates cell cycle progression from G1 to S phase and is a common oncogenic driver in gynecological malignancies. WEE1 kinase counteracts the effects of Cyclin E1/CDK2 activation by regulating multiple cell cycle checkpoints. Here we characterized the relationship between Cyclin E1/CDK2 activation and sensitivity to the selective WEE1 inhibitor azenosertib.

Background: The quality of life (QOL) of ovarian cancer patients is often impaired by refractory ascites. Cell-free and concentrated ascites reinfusion therapy (CART) is a palliative treatment for refractory ascites, but adverse events, such as fever, are problematic. Several cytokines have been suggested to be responsible for the adverse events, but they have not been investigated in detail.

Within ovarian cancer research, patient-derived xenograft (PDX) models recapitulate histologic features and genomic aberrations found in original tumors. However, conflicting data from published studies have demonstrated significant transcriptional differences between PDXs and original tumors, challenging the fidelity of these models. We employed a quantitative mass spectrometry-based proteomic approach coupled with generation of patient-specific databases using RNA-seq data to investigate the proteogenomic landscape of serially-passaged PDX models established from two patients with distinct subtypes of ovarian cancer.

Background: Ovarian cancer (OvC) constitutes significant management challenges primarily due to its late-stage diagnosis and the development of resistance to chemotherapy. The standard treatment regimen typically includes carboplatin and paclitaxel, with the addition of poly (ADP-ribose) polymerase inhibitors for patients with high-grade serous ovarian cancer (HGSOC) harboring BRCA1/2 mutations. However, the variability in treatment responses suggests the need to investigate factors beyond BRCA1/2 mutations, such as DNA repair mechanisms and epigenetic alterations.
