Is pulmonary metastasectomy beneficial in head and neck squamous cell carcinoma? A review of literature

Metastatic head and neck squamous cell carcinoma (HNSCC) has traditionally carried a dismal prognosis; however with advances in care, it has been shown that pulmonary metastasectomy is a viable therapeutic option in selected patients, palliating symptoms and improving survival. With the increasing incidence of human papilloma virus-related HNSCC and better availability of minimal access surgery, there is a need to better understand the role of pulmonary metastasectomy in the treatment of HNSCC. This article summarizes the literature on indications, results, surgical options and approaches, clinical dilemmas, and controversies associated with pulmonary metastasectomy in HNSCC, to identify suitable candidates and optimize outcomes.
