In this review of 105 consecutive patients who underwent operation for previously untreated, N0 squamous carcinomas arising in the oral tongue or the floor of the mouth, 86 percent of the determinate patients remained alive and well 2 years after treatment. Included were 48 patients, 49 patients, and 8 patients who had T1, T2, and T3 tumors respectively.(More)
BACKGROUND Angiogenesis is essential for the growth of solid tumors, including head and neck squamous cell carcinoma (HNSCC). Angiogenesis is regulated by angiogenic factors such as vascular endothelial growth factor (VEGF) and VEGF receptors (VEGFRs) 1, 2, and 3 known to be located on vascular endothelial cells (VECs). We hypothesize that VEGFRs are also(More)
During a recent 5-year period, 115 patients had 131 supraomohyoid neck dissections. Eighty-one percent of these procedures were performed for squamous carcinoma. Seventy-nine percent of the primary tumors were located in the oral cavity and 16 percent arose in the oropharynx. Almost 80 percent of the necks dissected for primary squamous carcinoma were(More)
OBJECTIVES We sought to identify the prevalence of human papillomavirus (HPV) in tonsillar squamous cell carcinoma, and to examine the relationship of HPV to prognosis and tumor morphology. METHODS We performed in situ hybridization for HPV and retrospective clinical outcome analysis. RESULTS Of the 48 patients with tonsillar carcinoma, in situ(More)
BACKGROUND Basic fibroblast growth factor (bFGF) is a potent angiogenic factor implicated in tumor growth and metastasis. To determine if bFGF and basic fibroblast growth factor receptor 1 (bFGFR1) and 2 (bFGFR2) are upregulated in head and neck squamous cell carcinoma (HNSCC), we measured the distribution and levels of each in HNSCC specimens and control(More)
BACKGROUND Nonsquamous cell malignant tumors of the nasal cavity and paranasal sinuses are an uncommon and diverse group of neoplasms. Our goal was to define the relative frequency and distribution of these neoplasms, as well as treatment and outcome. METHODS This retrospective study analyzed 106 patients with nonsquamous cell malignant neoplasms of the(More)
OBJECTIVE To test the hypothesis that interleukin-8 (IL-8) is produced by human head and neck squamous cell carcinomas (HNSCCAs) and may therefore be a possible mediator for lymphocyte recruitment and neovascularization by these tumors. METHODS Nine fresh samples of HNSCCA were analyzed for expression of IL-8 antigen using radioimmunoassay and(More)
Cytokines are known to play an important role in host defense by regulating the function, growth, and differentiation of the cells of the immune system. We hypothesize that, in the tumor microenvironment, tumor cells and resident tissue cells (e.g., fibroblasts) also produce cytokines that may regulate the local immune response to tumors. Initially,(More)
BACKGROUND Transforming growth factor beta (TGF-beta) has antiproliferative effects on normal and neoplastic cells that express specific TGF-beta receptors. We hypothesize that diminished expression of TGF-beta and/or its receptors may contribute to the uncontrolled proliferation of head and neck squamous cell carcinoma (HNSCCA) cancer cells. METHODS(More)
Most neoplasms arising in the parotid gland are benign. Patients with cancer of the parotid gland usually present with normal facial nerve function. In these patients, findings at the time of surgery will guide the management of the facial nerve, with most surgeons preserving the nerve unless it is adherent to, or imbedded in, a malignant tumor. In cases(More)
