Background: The prognostic significance of age in ovarian cancer has not been clarified. We investigated the characteristics of ovarian cancer presenting in ages > 70 years and assessed the prognostic significance of advanced age.
Patients And Methods: Four hundred and fifty-three patients with stage IIC-IV ovarian cancer (age>70 years n=106 [23%]), treated postoperatively with platinum-based chemotherapy were retrospectively reviewed.
Results: Median overall survival (OS) of patients 570 years old (52.3 months, 95% CI: 43.2-61.3) was longer than that of older patients (38.8 months, 95% CI: 29.9-47.7) (p =0.005), but this difference was not significant in a multivariate analysis (p=0.978). Age >70 years was correlated with worse performance status (PS) (p=0.019), higher tumor grade (p=0.033), residual disease >2 cm (p=0.006) and less frequent paclitaxel administration (p<0.001). Toxicity from chemotherapy was similar between the two age groups, but the relative dose intensity of paclitaxel was lower among elderly patients.
Conclusion: The worse outcome of ovarian cancer in elderly patients may be attributed to other associated adverse prognostic factors, but advanced age was not an independent prognostic factor.

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.
