Expression of Matrix Metalloproteinase-2/9 and Tissue Inhibitor of Metalloproteinase-1/2 as Predictive Factors in Oropharyngeal Squamous Cell Carcinoma

Introduction: Metalloproteinases and their tissue inhibitors play an important role in the metastases formation. A multistage process of carcinogenesis requires the involvement of numerous enzymes and compounds that facilitate the expansion of tumor cells. The formation of metastases depends on both metalloproteinases and tissue inhibitors activation leading to the acti...

A Comparative Study of CT Scan and MRI in The Assessment of Squamous Cell Carcinoma of The Oral Cavity and Its Cervical Lymph Node Metastasis

Introduction: Squamous Cell Carcinoma (SCC) is the most common head and neck malignancy. To decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. The main purpose of this prospective study is to compare the diagnostic value of Computed Tomography (CT) and Magnetic Resonance Im-aging (MRI) in oral SCC and its lymph ...

Prognostic factors in salvage surgery for recurrent oral and oropharyngeal cancer.

BACKGROUND Therapeutic decisions in recurrent oral and oropharyngeal squamous carcinoma (SCC) remain controversial. METHODS Two hundred forty-six consecutive patients who underwent salvage surgery for recurrent squamous cell carcinoma (SCC) of the oral cavity and oropharynx were studied. The tumor sites were lip, 33 cases; oral cavity, 143; oropharynx, 70. The previous treatment was surgery i...

S097 Prognostic Factors in Patients Undergoing Salvage Surgery of the Pharynx and Larynx

Purpose/Objectives:Radiation therapy has become the primary treatment modality for cancer of the pharynx and larynx in many institutions in the United States. In patients with recurrent head and neck cancer that have failed radiation with or without chemotherapy, salvage surgery is the preferred treatment modality for curative intent. Salvage surgery in the post radiation setting is a significa...
