title: Proton nuclear magnetic resonance spectroscopy of plasma lipoproteins in head and neck cancer patients.
abstract: Proton nuclear magnetic resonance spectroscopy was used to evaluate changes in plasma lipoproteins in patients with squamous cell head and neck cancer. Plasma from 14 patients was analyzed by proton nuclear magnetic resonance spectroscopy, and line widths and fast and slow methyl and methylene transverse relaxation values were obtained. In addition, the lipid and lipoprotein concentrations in the sera of these patients were measured by standard biochemical techniques. Preliminary results suggested that squamous cell carcinomas of the head and neck with nodal metastases are associated with measureable changes in slow methylene transverse relaxation values, as compared with controls. These findings indicate the presence of a new lipoprotein complex in patients with squamous cell carcinomas of the head and neck with nodal metastases.
