Introduction: Epithelial ovarian cancer (EOC) is the most prevalent type of ovarian cancer, yet the impact of ovarian laterality has received limited attention.
Materials And Methods: We conducted a comprehensive investigation into the impact of laterality (left-right and bilateral-unilateral) on EOC incidence and prognosis, focusing on distinct subtypes. Binomial tests and Pearson's χ2 tests were employed to compare occurrence rates among laterality groups. Cox regression analyses were used to create a proportional hazards model for tumor prognosis. Nomograms were developed and validated, including internal validation via bootstrapping.
Results: Our study encompassed 20,790 EOC patients, revealing disparities in incidence and prognosis between unilateral and bilateral cases. Unilateral tumor development was notably predominant in clear cell, endometrioid, brenner, and mucinous subtypes, while bilateral involvement was more frequent in serous ovarian cancer. Laterality differences, reflecting disparities between the left and right sides, were chiefly evident in the incidence rates across various stages and in the prognosis of specific subtypes. Notably, mucinous ovarian cancer exhibited significantly better prognosis on the right side compared to the left (right tumors: HR = 0.745, p = 0.015, CI: 0.587-0.945).
Conclusion: These findings emphasize the importance of considering ovarian laterality -both left-right and bilateral-unilateral aspects -as a critical factor influencing EOC incidence and prognosis, necessitating attention in clinical practice.

The objective of this study was to examine the efficacy of the concurrent utilization of estradiol valerate and kuntai capsule (a Chinese herbal preparation) in addressing premature ovarian failure (POF) and its ramifications for ovarian hemodynamics and sex hormone levels. A retrospective study of 104 patients with POF was conducted, dividing them into control (n=50) and observation groups (n=54). The control group received estradiol valerate, while the observation group received estradiol valerate and KunTai capsules over 12 weeks.

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.
