Survival after surgical resection of pulmonary metastases and second primary squamous cell lung carcinomas in head and neck cancer.

Background: Patients with head and neck squamous cell carcinoma (HNSCC) are at risk for developing both pulmonary metastasis and second primary lung cancer (SPLC). The objective of this study was to determine survival characteristics of patients with pulmonary lesions after curative treatment for HNSCC.

Methods: Lung resection or biopsy specimens of 36 patients, curatively treated for HNSCC between 1978 and 2002, were defined as second primary squamous cell lung cancer or metastasis by loss of heterozygosity (LOH analysis).
