Risk factors of lymph node metastasis in 559 patients with ovarian cancer in a single center andclinical decision of lymphadenectomy#br#

【Abstract】?Objective?To review the data of patients with ovarian cancer, analyze the related factors of pelvic lymph node metastasis (PLNM) and para-aortic lymph node metastasis (PALNM), and establish a predictive model, so as to provide suggestions for clinical practice. Methods?The clinicopathological data of 559 patients with ovarian cancer treated in Chinese PLA General Hospital from January 2014 to January 2019 were retrospectively analyzed. The risk factors affecting PLNM and PALNM were analyzed by univariate and logistic regression, and the prediction model was established. Results?Among 559 ovarian cancer patients, pelvic lymph node metastasis was found in 205 cases (36.67%) and abdominal para-aortic lymph node metastasis in 117 cases (20.93%). The independent risk factors affecting PLNM were bilateral lesions (OR=2.278, 95%CI: 1.433~3.621), pelvic metastases (OR=1.801, 95%CI: 1.154~2.810), and abdominal metastases (OR=4.177, 95%CI: 2.597~6.717) and appendiceal metastasis (OR=2.332, 95%CI: 1.389~3.915); The independent risk factors affecting PALNM were appendiceal metastasis (OR=2.324, 95%CI: 1.383~3.906) and PLNM (OR=7.629, 95%CI: 4.615~12.610). Age (≥55 years) (OR=0.566, 95%CI: 0.350~0.915) was the protective factor. The ROC curve AUC of PLNM and PALNM was 0.803 (95%CI: 0.767~0.840) and 0.793 (95%CI: 0.745~0.841), respectively. Conclusion?Bilateral lesions, pelvic metastases, intraperitoneal metastases and appendiceal metastases were independent risk factors for PLNM in ovarian cancer patients. Appendiceal metastasis and PLNM were independent risk factors for PALNM, and age (≥55 years) was the protective factor.
