Patients presenting with advanced disease but left without significant residual disease after surgery have a median survival of 39 months compared to 17 months for those with suboptimal tumor resection. If initial surgery does not produce minimal residual disease a second cytoreductive surgery has been used after the first three cycles of chemotherapy in one trial it was associated with a 6-month improvement in median duration of survival. Another randomized trial where more aggressive debulking surgery was initially carried out was unable to confirm this benefit. Prognosis of epithelial tumors is also highly influenced by histologic grade but less so by histologic type. Although grading systems differ among pathologists all grading systems show a better prognosis for well- or moderately differentiated tumors than for poorly differentiated histologies. Estimated 5-year survivals for patients by tumor grade are well-differentiated 88 moderately differentiated 58 poorly differentiated 27 . The prognostic significance of pre- and postoperative CA-125 levels is uncertain. CA-125 levels generally reflect volume of disease and
