摘要

背景:目的:研究影响浆液性卵巢癌(SOC)术后残留原发卵巢肿瘤或直肠附近转移病灶的风险因素:收集并回顾性分析A机构(培训组和测试组)164例符合条件的SOC患者和B机构(外部验证组)36例符合条件的SOC患者的临床和MRI数据。临床数据包括年龄、血清碳水化合物抗原125(CA-125)、人类附睾蛋白4和中性粒细胞与淋巴细胞比值(NLR)。磁共振成像(MRI)数据包括卵巢肿块分布、卵巢肿块最大直径、卵巢肿块特征、原发性卵巢肿瘤或转移病灶的直肠侵犯程度以及腹水量。利用多变量逻辑回归建立了一个模型:通过单变量和多变量逻辑回归,CA-125(P = 0.024,几率比[OR] = 3.798,95% 置信区间[CI] = 1.24-13.32)、NLR(P = 0.037,OR = 3.543,95% CI = 1.13-12.72)、原发卵巢肿瘤或转移病灶的直肠侵犯程度(P基于 T1 加权双回波 MRI 的临床放射学模型可用于无创预测直肠内接近 SOC 的术后残留卵巢肿瘤或转移灶。

Prediction of postoperative residual primary ovarian neoplasm or metastatic lesion close to rectum of serous ovarian carcinoma based on clinical and MR T1-DEI features.

Background: The optimal primary debulking surgery outcome of serous ovarian carcinoma (SOC) is greatly affected by primary ovarian neoplasm or metastatic lesion close to the rectum.

Purpose: To study the risk factors affecting postoperative residual primary ovarian neoplasm or metastatic lesion close to the rectum of SOC.

Material and methods: The clinical and MRI data of 164 patients with SOC eligible from institution A (training and test groups) and 36 patients with SOC eligible from institution B (external validation group) were collected and retrospectively analyzed. The clinical data included age, serum carbohydrate antigen 125 (CA-125), human epididymis protein 4, and neutrophil-to-lymphocyte ratio (NLR). Magnetic resonance imaging (MRI) data included ovarian mass distribution, maximum diameter of ovarian mass, ovarian mass features, degree of rectal invasion of the primary ovarian neoplasm or metastatic lesion, and amount of ascites. A model was established using multivariate logistic regression.

Results: By univariate and multivariate logistic regressions, CA-125 (P = 0.024, odds ratio [OR] = 3.798, 95% confidence interval [CI] = 1.24-13.32), NLR (P = 0.037, OR = 3.543, 95% CI = 1.13-12.72), and degree of rectal invasion of the primary ovarian neoplasm or metastatic lesion (P < 0.001, OR = 37.723, 95% CI = 7.46-266.88) were screened as independent predictors. The area under the curve values of the model in the training, test, and external validation groups were 0.860, 0.764, and 0.778, respectively.

Conclusion: The clinical-radiological model based on T1-weighted dual-echo MRI can be used non-invasively to predict postoperative residual ovarian neoplasm or metastasis close to SOC in the rectum.
