Background: The present study was conducted to determine the frequency and clinicopathological features of ovarian metastasis in a large population of patients with stage Ib-IIb cervical cancer.
Methods: The study population consisted of 3471 patients with stage Ib to IIb cervical cancer who underwent radical hysterectomy, including pelvic lymphadenectomy and bilateral salpingo-oophorectomy, at our six institutions between 1981 and 2000. To our knowledge, this study is the largest review of patients with ovarian metastasis from cervical cancer. We reviewed the patients' medical records to determine clinicopathological features.
Results: Fifty-two patients (1.50%) had ovarian metastases: 6 in stage Ib1, 12 in stage Ib2, 5 in stage IIa, and 29 in stage IIb. The mean age of patients with ovarian metastasis was 49.9 years (range: 29-73 years). The incidence of ovarian metastasis in patients with cervical cancer was 0.22% for stage Ib, 0.75% for stage IIa, and 2.17% for stage IIb with squamous cell carcinoma, and 3.72%, 5.26%, and 9.85%, respectively, in adenocarcinoma. Ovarian metastasis occurred more frequently among patients with adenocarcinoma than among those with squamous cell carcinoma (5.31% vs. 0.79%). Outcome for patients with ovarian metastasis was very poor and not related to FIGO stage and histological type. The presence of ovarian metastasis did not correlate with lymph node involvement or parametrial invasion.
Conclusion: Study results indicate that ovaries can be preserved in patients with stage Ib-IIa squamous cell carcinoma but removed in all patients with adenocarcinoma.

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.

Background: Clear cell ovarian carcinoma (CCOC) is a type of epithelial ovarian cancer, representing 5-11% of ovarian cancers. CCOCs tend to occur in the fifth to seventh decades of life, with only 10% of cases occurring in the fourth decade. On the other side, papillary thyroid carcinoma is the most common histology type of thyroid carcinoma and is associated with locoregional spread.

Cancer diagnosis and therapy cause stress to the body. Preclinical studies have shown that stress hormones can stimulate tumor progression and metastasis by interacting with β-adrenergic receptors, and that β-blockers can inhibit those processes. We assessed if β-blocker use was associated with survival in a nationwide cohort of women with epithelial ovarian cancer (EOC).

Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy which mainly consists of serous, mucinous, clear cell, and endometrioid subtypes. Due to the lack of classic symptoms at an early stage, EOC usually presented as advanced tumors with local and/or distant metastasis. Although a large portion of EOC was initially platinum-sensitive, most patients would acquire resistance to common chemotherapeutic agents.

To analyze the clinical characteristics, treatments, and prognosis of patients with ovarian juvenile granulosa cell tumor (JGCT). Clinical and pathological data, and follow-up information of 34 patients diagnosed with JGCT from 2000 to 2021 were collected from the surveillance, epidemiology, and end results (SEER) database. A retrospective analysis was conducted to summarize the patients' clinical and pathological characteristics, treatments, and prognosis.
