title: [Circulating tumor cells in head and neck cancer].
abstract: Circulating tumor cells are defined as tumor cells which are circulating in the peripheral blood of the cancer patient. While several large studies have investigated the role of circulating tumor cells in other solid tumors, the importance of these tumor cells in patients with head and neck cancer was turned into the focus not until the recent years. In other solid tumor the presence of circulating tumor cells often seems to be a negative prognostic marker and seems to be a marker for therapy response. The present article wants to give an overview about the knowledge on circulating tumor cells and their clinical relevance in head and neck cancer. The methodology to detect circulating tumor cells will be critically reflected. The future potential of the detection of circulating tumor cells in head and neck cancer patients will be discussed.
