术前磁共振成像及临床特征预测卵巢癌淋巴结转移的价值
Value of preoperative magnetic resonance imaging and clinical characteristics in predicting lymph node metastasis in ovarian cancer
目的 探讨术前磁共振成像(MRI)及临床特征预测卵巢癌淋巴结转移的价值。 方法 回顾性分析2022年1月—2025年1月新疆医科大学第五附属医院102例卵巢癌患者的临床资料,患者均行肿瘤减灭术治疗。依据病理检查结果,将有淋巴结转移的39例患者设为观察组,63例未发生转移者设为对照组。比较两组患者术前MRI影像学检查结果和临床病理资料。采用多因素一般Logistic回归模型分析患者发生淋巴结转移的风险因素,并构建列线图预测模型,通过校准曲线和受试者工作特征曲线评估模型的区分度与校准度。 结果 观察组Ⅲ、Ⅳ期、双侧病灶、低分化、术后残留病灶直径>2 cm的占比均高于对照组(P <0.05)。多因素一般Logistic回归分析结果表明,临床分期为Ⅲ、Ⅳ期[O^R =4.622(95% CI:1.647,12.970)]、病灶位置为双侧[O^R =6.182(95% CI:1.998,19.128)]及分化程度为低分化[O^R =0.222(95% CI:0.064,0.768)]均为卵巢癌淋巴结转移的危险因素(P <0.05)。 结论 基于术前MRI及临床特征构建的预测模型对卵巢癌淋巴结转移具有较高的预测价值,可为临床早期评估及治疗方案制定提供参考依据。
Objective To investigate the predictive value of preoperative magnetic resonance imaging (MRI) and clinical characteristics for lymph node metastasis in patients with ovarian cancer. Methods The clinical data of 102 ovarian cancer patients who received treatment at our hospital from January 2022 to January 2025 were retrospectively analyzed. All patients underwent cytoreductive surgery, and pathological specimens were examined. Patients with lymph node metastasis confirmed by pathology were assigned to the observation group (n = 39), and those without lymph node metastasis served as the control group (n = 63). Preoperative MRI findings and clinicopathological data were compared between the two groups. Risk factors for lymph node metastasis were identified by multivariate logistic regression analysis, and a nomogram prediction model was established. The performance of the model was evaluated using calibration curves and ROC curves. Results The proportion of patients in the observation group with stage III-IV, bilateral lesions, low differentiation, and postoperative residual lesion diameter > 2 cm was higher than that in the control group (all P < 0.05). Multivariate logistic regression analysis showed that stage III-IV [O^R = 4.622 (95% CI: 1.647, 12.970) ] and bilateral lesion location [O^R = 6.182 (95% CI: 1.998, 19.128) ] were independent risk factors for lymph node metastasis in ovarian cancer patients (P < 0.05). Conclusion The prediction model constructed by preoperative MRI combined with clinical features has high predictive value for lymph node metastasis in ovarian cancer patients, and can provide a reference for early clinical evaluation and treatment decision-making.
