Multispectral Imaging to Characterize Patterns of Vascular Supply Within Lymphoepithelial Mucosa in Oropharyngeal Cancer

Multispectral Imaging to Characterize Patterns of Vascular Supply Within the Lymphoepithelial Mucosa of Patients With Known or Suspected Oropharyngeal Carcinoma (OPC)

The purpose of this study is to characterize the blood supply at the base of the tongue and within the tonsil region. We hypothesize that high-resolution Narrow Band Imaging (NBI) will improve the diagnosis of oropharyngeal carcinoma (OPC). The goal is to provide the better assessment of tumor and thus providing better preoperative expectations to patients with OPC or tumor extent prior to radiation therapy.

Inclusion Criteria:

• age 18 years or older
• Written informed consent
• Patients with oropharyngeal carcinoma

Exclusion Criteria:

• Tumors of the oral cavity or nasopharynx
