Value of MRI in evaluating parametrial invasion and lymph node involvement of cervical carcinoma MRI评估宫颈癌宫旁侵犯和淋巴结转移的价值
Rectovaginal examination permits the best clinical assessment of tumor size and parametrial involvement. 经直肠阴道检查可以使肿瘤大小及相关参数在临床评估上达到最优。
The clinical analysis of the relationship between parametrial infiltration, as well as lymph-vascular space invasion and staging, prognosis of cervical cancer 宫颈癌宫旁及脉管浸润与分期关系的临床分析
Objective To determine the presence, distribution, and metastasis incidence of parametrial lymph nodes ( PLN) of patients with cervical cancer and to investigate the role of lymphatic mapping and topographic section in PLN identification. 目的探讨早期子宫颈癌患者宫旁淋巴结(PLN)存在与否及其分布、转移规律,进而评估以生物染料法(亚甲蓝染色)结合标本的局部解剖识别PLN的临床价值。
Lymph node metastasis was closely related to deep muscularis involvement of the cervix and parametrial involvement; 72.0% nodal metastases were accompanied with deep muscularis involvement of the cervix, 90.9% uterine ligament invasions were accompanied with lymph node metastasis. 淋巴结转移与宫颈深肌层侵犯、宫旁浸润之间关系密切,72.0%的淋巴结转移者同时存宫颈深肌层浸润,90.9%的宫旁韧带浸润者出现淋巴结转移。
Lymphatic mapping and parametrial lymph nodes identification in patients with early stage cervical cancer 早期子宫颈癌宫旁淋巴结的识别及其临床意义
The results suggest that the isotope nephrography was a method for judging the existence of advanced malignancy involving the parametrial tissues, the ureteral obstruction and impaired renal function in cervical cancer patients, The isotope nephrography can also be used for determining prognosis of the patients. 本文提示:肾图检查可作为宫颈癌患者宫旁浸润是否累及输尿管,并造成尿路梗阻及肾功能受损的有效诊断方法,也可作为判断宫颈癌患者预后的重要指标。
Results The accuracy, specificity, and sensitivity of parametrial invasion were 94%, 96% and 90%, respectively. 结果MRI对宫旁浸润判断的准确度为94%,特异度为96%,敏感度为90%。
The accuracy of MR imaging in determination of tumor location was 88.9%. The accuracy, specificity, and sensitivity for parametrial extension were 94%, 96%, and 90%, respectively. 磁共振成像对宫颈癌部位的判断的准确度为88.9%,对宫旁浸润判断的准确度为94%,特异度为96%,敏感度为90%。
Parametrial invasion was 80% sensitivity and specificity was 86.84%. 宫旁侵犯的灵敏度为80%,特异度为86.84%。
