Abstract
We evaluated lymphotropic nanoparticle enhanced magnetic resonance imaging (LNMRI) with ferumoxtran-10 in determining the presence of regional lymph node metastases in patients with penile cancer. Seven patients with squamous cell carcinoma of the penis underwent LNMRI. All patients subsequently underwent groin dissection and the nodal images were correlated with histology. We found that LNMRI had sensitivity, specificity, and positive and negative predictive values of 100%, 97%, 81.2% and 100%, respectively, in predicting the presence of regional lymph node metastases in patients with penile cancer. Lymph node scanning using LNMRI accurately predicts the pathological status of regional lymph nodes in patients with cancer of the penis. LNMRI may accurately triage patients for regional lymphadenectomy.
