Prediction of Lateral Pelvic Lymph-Node @entity3 in Low XXXX by Magnetic Resonance Imaging.

@entity1 @entity5 @entity3
OBJECTIVE: This study was designed to evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) for lateral pelvic lymph-node @entity3 . @entity1 : Eighty-four @entity1 with primary lower @entity5 were examined by MRI and subsequently underwent radical surgery with lateral pelvic lymph-node dissection, without preoperative treatment. Lateral lymph-node @entity3 were assessed preoperatively by MRI, and the results were compared with the histopathological findings. The criterion for lateral lymph-node @entity3 was any recognizable lymph node in the pelvic wall, regardless of diameter. RESULT: Lateral pelvic lymph-node @entity3 was diagnosed on preoperative MRI in 16 @entity1 (19.9  %). The overall @entity1 -based sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of MRI were 75, 69.1, 36.4, 92.2, and 70.2  %, respectively. When a cut-off value of 10  mm was used for diagnosis, the corresponding values were 43.8, 98.5, 87.5, 88.1, and 88.1  %, respectively. The mean diameter of metastatic nodes (14.7  mm) was significantly larger than that of negative nodes (5.7  mm; P  <  0.01). CONCLUSION: MRI is an effective technique for predicting lateral pelvic node involvement and thus may facilitate preoperative decision-making in @entity5 treatment. A cut-off value of 10  mm is useful for avoiding unnecessary lateral lymph-node dissection.
