title: [Evaluation of p53 and soluble Fas ligand (sFasL) serum level concentration as indicators of apoptosis in serum of patients with benign and malignant primary follicular thyroid tumors].
abstract: BACKGROUND
  Apoptosis (programmed cell death) is the best described mode of physiological cell death. During embryonal development and morphogenesis, apoptosis may be induced by two pathways. The first is external protein signal originating from other cell--also named as "death signal". Another one is specific cell reaction for external stress factors. Blood concentration of proteins regulating both pathways of apoptosis may be useful in early diagnosis and staging of thyroid tumors. The aim of study was evaluation of p53 and sFasL blood concentration in patients with benign follicular adenoma and follicular thyroid cancer.
  
  
  METHODS
  The study population was composed of 28 patients: 14 with thyroid carcinoma and 14 patients with follicular neoplasm (NF). All patients underwent surgical treatment. P53 and sFasL levels were evaluated before surgery and related to the histopathological diagnosis obtained post-surgery.
  
  
  RESULTS
  The analysis revealed high sFasL blood concentration in patients with follicular thyroid cancer in comparison with the group with follicular adenoma. There was no statistically significant difference between levels of p53 in both groups.
  
  
  CONCLUSIONS
  Evaluation of sFasL serum level concentration may be useful in preoperative diagnosis of follicular thyroid tumors.
