Markedly elevated levels of vascular endothelial growth factor, fibroblast growth factor, and interleukin 6 in Meigs syndrome.

Analysis of serum and peritoneal and pleural fluid from a patient with Meigs' syndrome revealed high levels of vascular endothelial growth factor, fibroblast growth factor, and interleukin 6. Serum levels declined after removal of the ovarian tumor, along with resolution of ascites and hydrothorax. These findings suggest the involvement of these vasoactive factors in ascites and pleural fluid formation in Meigs' syndrome.
