Limited utility of conventional criteria for predicting unresectable disease in patients with advanced stage epithelial ovarian cancer.

Abstract：

OBJECTIVE:To evaluate the predictive value of conventional criteria for identifying surgically unresectable disease among patients with ovarian cancer undergoing initial operative intervention at tertiary referral centers employing a so-called aggressive approach to surgical cytoreduction. METHODS:All patients with advanced epithelial ovarian cancer undergoing primary surgery between August 1997 and August 2006 were identified. Surgical/pathological documentation of disease extent pre/post-cytoreduction was extracted from the medical record retrospectively. All patients meeting conventional criteria for unresectable disease criteria (ascites >1000 mL, omental extension to spleen >1 cm, parenchymal liver disease >1 cm, porta hepatis involvement >1 cm, diaphragmatic disease >1 cm, carcinomatosis >1 cm, and suprarenal adenopathy >1 cm) were selected for further study. RESULTS:A total of 180 consecutive patients had disease meeting conventional criteria for unresectability at =1 site(s). Optimal cytoreduction (residual disease=1 cm) was achieved in 166 patients (92.2%). Optimal resection rates according to the most common individual unresectable disease criteria were as follows: ascites >1000 mL=91.3% (116/127), carcinomatosis >1 cm=91.0% (81/89), and splenic involvement >1 cm=84.9% (45/53). For patients with ascites >1000 mL alone, optimal cytoreduction was achieved in 95.8% (46/48) of cases. Optimal resection rates according to the total number of unresectable disease sites were as follows: 1 site=95.0% (19/20), 2 sites=93.8% (61/65), 3 sites=81.5% (22/27), 4 sites=93.3% (14/15), and 5 sites=80.0% (4/5). CONCLUSIONS:These data suggest that commonly accepted criteria of surgically unresectable disease for women with advanced ovarian cancer lack the necessary precision to guide clinical management. Pre-operative assessment of resectability should be made by an experienced surgical team prior to deferring the initial attempt at surgical cytoreduction.
