RT Journal Article SR Electronic T1 Distribution Pattern of Circumflex Iliac Node Distal to the External Iliac Node Metastasis in Stage IA to IIA Cervical Carcinoma JF International Journal of Gynecologic Cancer JO Int J Gynecol Cancer FD BMJ Publishing Group Ltd SP 935 OP 940 DO 10.1097/IGC.0000000000000138 VO 24 IS 5 A1 Yue-ju Yin A1 Hui-qin Li A1 Xiu-gui Sheng A1 Xing-lan Li A1 Xiang Wang YR 2014 UL http://ijgc.bmj.com/content/24/5/935.abstract AB Objectives This study aimed to investigate the metastatic rate of circumflex iliac node distal to the external iliac node (CINDEIN) and its associations with clinicopathological factors in patients with stage IA to IIA cervical cancer to determine whether dissection of CINDEIN had a role in surgery of these patients.Methods Six hundred thirty-three patients with the International Federation of Gynecology and Obstetrics stage IA to IIA cervical cancer who underwent radical hysterectomy and pelvic lymphadenectomy were retrospectively reviewed. The metastatic rate and distribution of the pelvic lymph nodes (PLNs) and CINDEINs were analyzed.Results The PLN metastatic rate was 25.6% (162 of 633 patients). Sixteen of 162 node-positive patients had CINDEIN metastases. Only 1 patient without PLN metastases had positive CINDEIN nodes. Univariate analysis revealed that other PLNs (including lymph nodes collected from obturator, external iliac, and internal iliac regions) and lymph vascular space involvement were the risk factors of CINDEIN metastases (P < 0.05). Other PLN metastasis (odds ratio, 50.6; 95% confidence interval, 6.6–386.7) was an independent risk factor for metastasis to CINDEIN by binary logistic regression analysis.Conclusions Circumflex iliac node distal to the external iliac node metastases seemed to occur secondarily to widespread PLN metastases. In early stage cervical cancer, removal of the CINDEIN as a routine surgical procedure might be omitted to reduce operation time and minimize surgical morbidity.
