## Abstract ## Background. Treatment of head and neck squamous cell carcinoma (HNSCC) addresses the primary tumor and the lymphatic drainage. Modalities for the neck are neck dissection and/or radiation therapy. In most cases, the neck is treated by the modality that seems more appropriate for the

Abstract
Background
Thyroid carcinoma occurring as a second primary associated with head and neck squamous cell carcinoma (HNSCC) is unusual. The clinical management of thyroid cancer in such cases has been debated.
Methods
Between 1975 and 2004, we collected 33 cases. The associated thyroid carcinoma was diagnosed either during or as a consequence of surgery planned as head and neck cancer treatment.
Results
The associated thyroid carcinoma was never seen to recur. Fiveβyear overall survival was 41%. Diseaseβfree survival after 40 and 66 months was 11.1% and 5.6%, respectively.
Conclusions
We consider the treatment of thyroid cancer to be complete when the thyroid gland, either with or without lymph nodes, has been included in the specimen obtained during surgery for HNSCC. In the group of cases in which associated thyroid carcinoma was only found within the neck lymph nodes and the thyroid gland has not been treated, we discourage further surgical treatment or radioactive iodine therapy.

Background and Objectives: Carcinoma of the head and neck is an uncommon primary source of bone metastases. The increasing duration of survival of these patients, however, increases the probability of late bone involvement. The objective was to identify the frequency, clinical presentation, and clin
## Abstract Head and neck cancer is a challenging disease that is expected to account for greater than 500,000 new cases worldwide in 2008. Toxicity has impeded advances in chemotherapy and radiation for head and neck cancer, and the prognosis for patients with recurrent and/or metastatic disease r
Basaloid squamous cell carcinoma (BSCC) of the head and neck is a recently described high-grade variant of squamous cell carcinoma. It is a biologically virulent neoplasm with a propensity for nodal, as well as systemic, metastases. Because of the limited number of published reports, we reviewed dat
Gm, A2m, and Km allotypic markers were examined in 40 Caucasian patients with squamous cell carcinomas of the head and neck. Serum IgA levels, the A2m(l) allotypic marker, and antibodies against IgAl, A2m(l), and A2m(2) were measured quantitatively. The frequency of Km(1) was found to be significant
