title: High levels of xenoestrogens in patients with low-grade endometrial stromal sarcoma--report of two cases.
abstract: BACKGROUND
  Endometrial stromal sarcomas (ESS) are rare uterine tumors with unknown etiological risk factors, but estrogen-dependent growth promotion.
  
  
  METHODS
  We present two patients with advanced ESS, who had increased levels of p,p-DDE; hexachlorobenzene; PCB 28; PCB 52; PCB 101; PCB 138; PCB 153 and PCB 180 in abdominal adipose tissue. Other xenoestrogens were within expected limits for the non-exposed European population.
  
  
  CONCLUSIONS
  Increased levels of xenoestrogens in patients with ESS may be involved in the pathogenesis of ESS. Chronic exposure to xenoestrogens may be a risk factor for tumor progression.
