Background: Increasing evidence, including multiple putative inflammatory risk factors (e.g., c-reactive protein, and adiposity), supports that inflammation plays an important role in ovarian carcinogenesis. Resistance training (RT) is associated with lower levels of circulating inflammatory markers, independent of physical activity.
Methods: We evaluated the relationship between RT and risk of ovarian cancer accounting for other physical activity (e.g., walking) in two large prospective cohorts, the Nurses' Health Study (NHS) and NHSII.
Key Results: In total, analyses included 42,005 NHS participants (2000-2016) and 67,289 NHSII participants (2001-2017) with RT assessed every 4 years. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of RT with ovarian cancer risk overall and by tumor subtype, adjusting for known and putative ovarian cancer risk factors. We identified a total of 609 cases over 1,748,884 person-years. No association was observed with overall ovarian cancer risk (RT ≥60 vs 0 min/wk, HR = 0.95, 95%CI: 0.74-1.22) or by histotype (comparable HR = 0.86 and 0.98 for type I and II tumors, respectively). Results did not differ by body mass index (Pinteraction = 0.97), or other physical activity (Pinteraction = 0.31).
Conclusions & Inferences: We observed no evidence that moderate levels of RT were associated with risk of ovarian cancer. Further investigations are required to confirm these findings.

Background: Randomized clinical trials (RCTs) are fundamental to evidence-based medicine, but their real-world impact on clinical practice often remains unmonitored. Leveraging large-scale real-world data can enable systematic monitoring of RCT effects. We aimed to develop a reproducible framework using real-world data to assess how major RCTs influence medical practice, using two pivotal surgical RCTs in gynaecologic oncology as an example-the LACC (Laparoscopic Approach to Cervical Cancer) and LION (Lymphadenectomy in Ovarian Neoplasms) trials.

Ovarian cancer (OC) remains one of the most lethal gynecological malignancies, largely due to its late-stage diagnosis and high recurrence rates. Chronic inflammation is a critical driver of OC progression, contributing to immune evasion, tumor growth, and metastasis. Inflammatory cytokines, including IL-6, TNF-α, and IL-8, as well as key signaling pathways such as nuclear factor kappa B (NF-kB) and signal transducer and activator of transcription 3 (STAT3), are upregulated in OC, promoting a tumor-promoting environment.

Objective: To investigate the correlation between endometriosis (EMs) severity and placenta accreta spectrum (PAS) risk in the subsequent pregnancy.
Method: Clinical records of 2,142 patients who underwent laparoscopic surgery for EMs at Fujian Provincial Maternal and Child Health Hospital from January 2014 to January 2018, who had achieved pregnancy and were delivered, were analyzed. Baseline data, EMs stage, The Revised American Fertility Society (R-AFS) score, levels of serum indexes, and pregnancy and neonatal outcomes were recorded.

Background: Mitochondrial genes are involved in tumor metabolism in ovarian cancer (OC) and affect immune cell infiltration and treatment responses.
Aim: To predict prognosis and immunotherapy response in patients diagnosed with OC using mitochondrial genes and neural networks.
Methods: Prognosis, immunotherapy efficacy, and next-generation sequencing data of patients with OC were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus.

This research aims to optimize adjuvant ovarian function suppression (OFS) for premenopausal Indian women with hormone receptor-positive (HR+) /human epidermal growth factor receptor 2-negative (HER2-) early breast cancer (eBC). To address specific challenges identified in clinical practice, a comprehensive questionnaire consisting of 21 statements was developed. These statements were reviewed and validated by a scientific committee, ensuring their accuracy and relevance to the study's objectives.
