Search for primary tumor in metastatic lymph nodes of the neck

The efficiency of combined positron emission and computer tomography in the diagnosis of primary metastatic lymph nodes of the neck was analyzed. It was established that in 34% fully examined patients was identified the primary tumor. In 32% of patients was detected distant metastases to other organs and lymph nodes. In more than 60% of patients using this method provided additional information and influence on the tactics of their treatment. Thus we believe that PET-CT should be included in diagnostic algorithm of this category of patients.
