Nomogram prediction model based on non-enhanced computed tomography for adnexal torsion: A retrospective multicenter study.
Int J Gynaecol Obstet
January 2025
Department of Radiology, Affiliated Hospital 2 of Nantong University, Nantong City, Jiangsu Province, China.
Objective: To develop and validate an individualized nomogram for predicting adnexal torsion in women with abdominal pain and an adnexal mass based on preoperative non-contrast computed tomography (CT) findings.
Methods: This retrospective study included 200 women with surgically resected ovarian lesions who underwent preoperative non-contrast CT for abdominal pain from January 2017 to September 2023 in seven hospitals. The 200 patients were randomly divided into a development group (140 cases) and a validation group (60 cases).
Quantifying intratumoral biomarker heterogeneity in tubo-ovarian high-grade serous carcinoma to optimize clinical translation.

Intratumoral heterogeneity (ITH) is spatial, phenotypic, or molecular differences within the same tumor that have important implications for accurate tumor classification and assessment of predictive biomarkers. The Canadian Ovarian Experimental Unified Resource (COEUR) has created a cohort of 437 FFPE tissue specimens from 108 tubo-ovarian high-grade serous carcinoma (HGSC) patients to quantify ITH across the anatomical sites and between primary and recurrence. We quantified the ITH of six clinically used immunohistochemical diagnostic and prognostic biomarkers (WT1, p53, p16, PR, CD8, and Ki67).

Pelvic masses in women can originate from both gynecological and non-gynecological sources, necessitating careful evaluation to ensure appropriate treatment. Gynecological masses can range from functional ovarian cysts and tubo-ovarian abscesses to malignant and benign tumors. This case report presents a mucinous borderline ovarian tumor (BOT), a rare type of ovarian neoplasm.

Article Synopsis
- Fusion is an emerging target in precision oncology, found in various solid tumors, but research is often focused on more common types, creating challenges in treatment planning for rare cases.
- The case presented involves a rare high-grade serous tubo-ovarian carcinoma with a unique fusion, which responded briefly to the drug futibatinib.
- The study explores the possible mechanisms behind this fusion and highlights difficulties in predicting how effective targeted therapies will be for different tumor types that share similar structural variants.
Tertiary lymphoid structures in high-grade serous tubo-ovarian carcinoma: anatomical site matters.

Division of Oncology, Department of Clinical Sciences Lund, and Lund University Cancer Center, Lund University, Lund, Sweden.
Tertiary lymphoid structures (TLS) in the tumor microenvironment are prognostically beneficial in many solid cancer types. Reports on TLS in high-grade serous tubo-ovarian carcinoma (HGSC) are few, and the prognostic impact is unclear. We investigated mature TLS (mTLS), immature TLS (iTLS) and lymphoid aggregates (LA) in primary adnexal tumors (PTs) and synchronous omental/peritoneal metastases (pMets) of HGSC.
