[Predictive value of preoperative abdominopelvic CT for optimal cytoreduction surgery in ovarian carcinoma].

Some patients underwent laparoscopy without optimal debulking surgery as initial treatment for advanced ovarian carcinoma. The amount of residual tumor following primary surgery was an important prognosis factor. Neoadjuvant chemotherapy is a new therapeutic approach. Secondary, optimal surgery could be done in better conditions. The purpose was to access the ability of preoperative abdominopelvic CT to predict success of debulking surgery for ovarian carcinoma: less than 1 cm of residual tumor size after initial surgery. We reviewed 39 patients (2 stages Ic, 1 stage IIc, 22 stages III and 14 stages IV) operated on for ovarian carcinoma between January 1992 and December 1997. Surgical criteria of inability to perform optimal surgical cytoreduction were compared with abdominopelvic CT done the month before. CT scans were prospectively assessed by radiologist A and retrospectively (3 months to 6 years delay) rewiewed separately by radiologists A and B without surgical data. Nineteen patients underwent optimal debulking surgery: 13 no residual tumor and 6 with residual lesions under 1 cm. The interreader (0.73) and intrareader (0.9) agreement, worked out by Kappa coefficient, was juged good to very good. The sensitivity of CT was 91% with a specificity of 95%. These results allowed us to determine wich CT criteria were accurate and reproducible to be a helpfull for therapeutic choice and to avoid laparotomy without optimal surgery.
