Nodal involvement evaluation in advanced cervical cancer: a single institutional experience
Purpose: To assess the usefulness of different imaging techniques in the detection of nodal involvement in patients with advanced
cervical carcinoma. Moreover, to analyze the correlation between the presurgical (FIGO) and postsurgical (pTNM) staging classifications.
Materials and Methods: All patients diagnosed with advanced cervical cancer (FIGO Stages IIB-IV) from 2005 to 2012 were
selected. The medical charts of 51 patients that underwent presurgical assessment with posterior surgical staging by means of paraaortic
lymphadenectomy, were reviewed. Nodal status assessment by computed tomography scan (CT scan), magnetic resonance
imaging (MRI), positron emission tomography (PET), and sonography was compared, as well as the size given in imaging techniques
compared to the final pathologic report information. Results: Presurgical analysis by CT scan, MRI, PET, and sonography showed
pelvic nodal involvement in 51.3% of patients, and para-aortic involvement in 30.8% of cases. CT scan showed positive pelvic nodes
in 35% of cases, but pathologic confirmation was observed in just 17.6% of cases. However, MRI resulted in higher rates of up to
48.8% of cases. Concerning para-aortic nodal involvement, CT scan showed positive nodes in 25% of cases, MRI in 3.2% of cases,
and the pathologic report in 15.6% of cases. The authors found significant differences between staging groups among both classifications
(FIGO vs. pTNM; p < 0.001). Eight cases (15.7%) were understaged by FIGO classification. Conclusions: Despite all imaging
techniques available, none has demonstrated to be efficient enough to avoid the systematic study of para-aortic nodal status by
means of surgical evaluatio
