诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

手术患者的金标准:术后切除标本的组织病理学诊断;非手术患者的金标准:>=6个月的多模态影像随访(超声/MRI每3个月1次)联合临床结局(肿瘤标志物、症状变化)综合评估:良性判定:病变稳定/缩小且标志物正常;恶性判定:病变进展(体积增大>=10%或新转移)且标志物持续升高,或经其他途径(腹水细胞学/转移灶活检)证实恶性。金标准判定时间点:末次入组患者完成6个月随访后。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Gold standard for surgical patients: histopathological diagnosis of postoperative resected specimens; Gold standard for non-surgical patients: > = 6 months of multimodal imaging follow-up (ultrasound/MRI once every 3 months) combined with comprehensive assessment of clinical outcomes (tumor markers, symptom changes): benign judgment: stable/shrinking lesions and normal markers; Malignancy: progression of lesions (volume increase >=10% or new metastases) with persistently elevated markers, or confirmation of malignancy by other routes (ascites cytology/metastases). Gold standard time point: after the last enrolled patients completed 6 months of follow-up.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

Index test:

Contrast-Enhanced Ultrasound-Guided Ovarian Biopsy Group (CEUS Group) Contrast agent: Sulfur Hexafluoride Microbubbles for Injection (SonoVue?, Bracco) Equipment: High-end ultrasound diagnostic systems (e.g., Philips EPIQ 7/Mindray Resona R9) with low mechanical index (MI) contrast mode enabled (MI < 0.2) Biopsy needle: 18G automatic biopsy needle (Bard Magnum?) Procedure: a) Transabdominal conventional ultrasound to localize the lesion b) Bolus injection of 2.4 mL contrast agent via elbow vein, followed by flushing with 5 mL normal saline c) Real-time observation of lesion enhancement characteristics within 120 seconds (arterial phase/venous phase) d) Puncture targeting the most diagnostically valuable enhanced areas (e.g., early hyperenhanced regions in malignant tumors) e) Collection of >=3 tissue cores per sampling Conventional Ultrasound-Guided Ovarian Biopsy Group (US Group) Equipment: Same ultrasound system and transducer (with contrast function disabled) Biopsy needle: 18G automatic biopsy needle of the same specification Procedure: a) Transabdominal grayscale ultrasound to measure lesion size b) Color Doppler to avoid vascular-rich areas c) Sampling from solid components or vascular-rich regions d) Collection of >=3 tissue cores per sampling

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

本研究连续纳入18-75岁因卵巢占位需病理诊断的女性患者,病灶经腹超声评估符合: 1.最大径>=2cm; 2.含实性成分(>=30%体积)或混合性包块实性部分>=1cm; 3.囊壁/分隔血流RI<0.8; 4.临床指征包括:CA125/HE4异常升高、RMI>=200、绝经后新发包块或包块持续存在>=3个月; 5.覆盖病变全谱:良性肿瘤(如畸胎瘤)、交界性肿瘤、恶性肿瘤(上皮癌/生殖细胞肿瘤等)。

例数:

Sample size:

264

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

In this study, female patients aged 18-75 years who require pathological diagnosis due to ovarian mass were continuously included, and the transabdominal ultrasound evaluation of the lesions was consistent with: 1. Maximum diameter >=2cm; 2. Solid components (> = 30% volume) or solid parts of mixed masses > = 1cm; 3. Cyst wall/septated blood flow RI< 0.8; 4. Clinical indications include: abnormal elevation of CA125/HE4, RMI>=200, new postmenopausal masses or persistent masses >=3 months; 5. Covering the full spectrum of lesions: benign tumors (such as teratomas), borderline tumors, malignant tumors (epithelial cancer/germ cell tumors, etc.).
