PROBLEM: The aim of this study was to evaluate serum and urinary levels of vascular endothelial growth factors, tumor necrosis factor-alpha (TNF-alpha), and soluble fms-like tyrosine kinase (sFlt-1) in patients with endometriosis. METHOD OF STUDY: During surgery for pelvic pain, pelvic mass or infertility, serum and urine were collected. Of 70 patients, 46 had histology-proven endometriosis and 24 patients without endometriosis participated as controls. RESULTS: Serum TNF-alpha levels and urinary sFlt-1 levels corrected for creatinine excretion were significantly increased in the endometriosis group (P=0.001 and P=0.011 respectively). Serum sFlt-1 levels and urinary sFlt-1 levels corrected for creatinine were significantly higher in patients with minimal-to-mild disease (P=0.014 and P=0.015 respectively), where serum TNF-alpha levels were increased in moderate-to-severe endometriosis (P<0.001). CONCLUSION: The pathogenesis of minimal-to-mild endometriosis and moderate-to-severe endometriosis seems to be different. Increased sFlt-1 levels in serum and urine of minimal-to-mild disease indicate that sFlt-1 may have an important role in inhibiting angiogenic process of the disease.
