title: Loss of heterozygosity in mammary serine protease inhibitor (maspin) and p53 at chromosome 17 and 18 in oral cavity squamous cell carcinoma.
abstract: BACKGROUND
  The purpose of this study was to evaluate the loss of heterozygosity (LOH) in chromosomes 17p13 (p53 gene) and in 18q21 (mammary serine protease inhibitor [maspin] gene), and the expression of both genes in tissues, in patients with oral cavity squamous cell carcinoma (SCC).
  
  
  METHODS
  Thirty patients with oral cavity SCC have been evaluated for the presence of LOH in chromosomes 17p13 and 18q21, and the expression of p53 and maspin in tissues. Clinicopathological features and survival in these patients were also analyzed.
  
  
  RESULTS
  LOH in 17p13 was more frequently identified in patients with lymph node metastasis and/or high TNM classification. LOH in 18q21 was more frequently identified in high primary T classification patients. Increased expression rate of p53 and/or decreased maspin expression rate were significantly higher in oral cavity SCC than normal tissues.
  
  
  CONCLUSIONS
  LOH on chromosome 17, 18, the expression of p53, and maspin are related to the carcinogenesis of oral cavity SCC. Relationships with clinicopathological factors in oral cavity SCC were also revealed. © 2014 Wiley Periodicals, Inc. Head Neck 37: 1239-1245, 2015.
