Background: Extended-field chemoradiation therapy is usually performed in patients with locally advanced cervical cancer (LACC) and paraaortic (PA) node metastases. Considering the very low rate of skip metastases above inferior mesenteric artery, ilio-inframesenteric paraaortic lymph node dissection (IM-PALND) seems to be an adequate pattern of PALND. Our objective was to assess the accuracy of this management to determine PA nodal status in comparison with infrarenal paraaortic lymphadenectomy (IR-PALND) in case of squamous or glandular cervical cancer., Methods: All patients with LACC and negative MRI and PET/CT imaging at paraaortic level had laparoscopic staging (followed, if negative, by extraperitoneal paraaortic lymphadenectomy). From January 2011 to September 2015, patients who had IM-PALND were included and were compared to a previous historical series of IR-PALND patients. The two groups differed only at the upper level of dissection. Characteristics of nodal involvement at paraaortic level depending on level of dissection, PET/CT imaging and histology were studied., Results: 119 women were included in our study, with 56 patients in the IM-PALND group and 63 in the IR-PALND group. In the IM-PALND group, fewer nodes were resected (p<0.001). There was no difference between the two groups regarding nodal status at paraaortic level (p=0.77). Patterns of nodal involvement were similar whichever the histological subtype of cervical cancer (squamous or glandular)., Conclusion: IM-PALND appears to be equally effective to assess paraaortic nodal involvement in LACC for both histological subtypes - glandular and squamous carcinomas - and to select patients for extended-field chemoradiation therapy., (Copyright © 2017 Elsevier Inc.

Objective: Extended-field chemoradiation is typically used for the management of patients with locally advanced cervical cancer. Given the low rate of skipped metastases above the inferior mesenteric artery, ilioinframesenteric dissection seems to be an acceptable pattern of paraaortic lymph node dissection (LND). Our objective is to compare the surgical morbidity of inframesenteric LND (IM-LND) with infrarenal LND (IR-LND)., Methods: In our center, all of the patients with locally advanced cervical cancer and negative magnetic resonance imaging and positron emission tomography-computed tomography imaging at the paraaortic level were offered laparoscopic staging including a diagnostic laparoscopy followed, if negative, by an extraperitoneal paraaortic lymphadenectomy. From January 2011 to September 2015, we included patients who had paraaortic LND from both common iliac bifurcations and divided them into 2 groups according to dissection pattern: to the inferior mesenteric artery (IM-LND) level or to the left renal vein (IR-LND) level. The perioperative and postoperative data were retrospectively recorded., Results: A total of 119 women were included in our study: 56 in the IM-LND group and 63 in the IR-LND group. There was no difference in the patients' characteristics between groups. Regarding the surgical procedure, the operating time was shorter in the IM-LND group than the IR-LND group, 174 ± 50 minutes versus 209 ± 61 minutes (P = 0.001), respectively. There was no significant difference in intra- and postoperative complications, overall survival, or progression-free survival., Conclusions: In our series, exclusive IM-LND surgery is faster than IR-LND and results in similar morbidity and survival rates. These results confirm the feasibility and the applicability of IM-LND to simplify the surgical procedure without impacting survival. More patients should be included in the study to demonstrate the lower rate of morbidity.
