Relationship between lymph node metastases and the prognosis of uterine cervical cancer patients diagnosed at stage Ⅲ C1p after abdominal surgery / 肿瘤研究与临床

ABSTRACT

Objective:To investigate the relationship between lymph node metastases and the prognosis of uterine cervical cancer patients diagnosed at Ⅲ C1p after abdominal surgery. Methods:The clinical data of 350 uterine cervical cancer patients preoperatively confirmed as 2018 International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ B-Ⅱ A who underwent abdominal hysterectomy followed by postoperative concurrent chemoradiotherapy between January 2012 and December 2019 at Subei People's Hospital of Jiangsu Province were retrospectively analyzed, and there were 81 patients postoperatively diagnosed at stage Ⅲ C1p. Kaplan-Meier method was used to analyze the survival of patients stratified by different factors, and multivariate Cox proportional risk model was used to analyze the factors affecting the prognosis of patients. Results:Among 81 uterine cervical cancer patients diagnosed at stage Ⅲ C1p after abdominal surgery, 79 cases were successfully followed up. Kaplan-Meier analysis showed that patients with parametrial infiltration, the number of metastatic lymph nodes > 2, metastatic lymph node rate > 20 and common iliac lymph node metastasis had worse disease-free survival (DFS) and the overall survival (OS) (all P < 0.05). Multivariate Cox proportional analysis showed that the number of metastatic lymph nodes > 2 ( HR = 5.38,95% CI 1.30-22.20, P = 0.020) was an independent risk factor for OS; the number of metastatic lymph nodes >2 ( HR = 5.99, 95% CI 1.45-24.77, P = 0.013), common iliac lymph node metastasis ( HR = 4.91, 95% CI 1.17-20.55, P = 0.029) were independent risk factors for DFS. Conclusion:Lymph node metastasis may be associated with the prognosis of uterine cervical cancer patients diagnosed at stage Ⅲ C1p after abdominal surgery. The number of metastatic lymph nodes > 2 is a adverse influencing factor for OS and DFS.
