Oligometastatic head and neck cancer: Comprehensive review.

Abstract

There are limited data available regarding the management of oligometastatic squamous cell carcinoma of the head and neck (SCCHN) patients, and no consensus guidelines are available. The objective is to review the available literature for the management of oligometastatic SCCHN. Articles were selected from English Medline literature between 1995 and 2018, searched by using the keywords: oligometastatic SCCHN/metastasectomy/stereotactic body radiation treatment (SBRT). With the available data, oligometastatic SCCHN patients appear to behave differently and tend to have a better prognosis than those with widespread metastases. Retrospective evidence suggests that the aggressive treatment of the primary disease and local treatment of the metastatic sites improves survival in oligometastatic SCCHN at diagnosis. The definitive treatment of the distant metastatic sites using metastasectomy or SBRT correlates with better survival in oligorecurrent patients. Oligometastatic SCCHN patients may have a better prognosis if treated aggressively.
