Pretherapeutic staging of locally advanced cervical cancer: Inframesenteric paraaortic lymphadenectomy accuracy to detect paraaortic metastases in comparison with infrarenal paraaortic lymphadenectomy
Abstract : 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.
