title: Immunohistochemical detection of c-myc protein in head and neck tumors.
abstract: OBJECTIVE
  To evaluate the correlation between the levels of immunohistochemically detectable c-myc protein in squamous cell carcinoma of the head and neck and clinicopathologic prognostic variables utilized in clinical practice.
  
  
  METHODS
  Cohort study.
  
  
  METHODS
  University and Veterans Administration medical centers, Cincinnati, Ohio.
  
  
  METHODS
  Consecutive samples.
  
  
  METHODS
  Surgery for squamous cell carcinoma of the head and neck.
  
  
  METHODS
  Correlation between c-myc expression and tumor size, nodal involvement, clinical disease stage, and degree of differentiation. Hypothesis formulated after data collection.
  
  
  RESULTS
  Significant negative correlation between the c-myc levels and the number of metastatic nodes (P = .0001) and clinical stage of disease (P = .05). No correlation with tumor size or degree of differentiation.
  
  
  CONCLUSIONS
  Reduction or loss of c-myc oncoprotein might be associated with metastatic lymph node involvement and advanced stages of squamous cell carcinoma of the head and neck. Further studies are needed to substantiate preliminary findings.
