Interval laparoscopy as predictor of response to chemotherapy in ovarian carcinoma

Fifty-one patients with FIGO stage III and IV ovarian adenocarcinoma underwent six-month interval laparoscopy for assessment of chemotherapy response. Thirty-nine of these patients were followed by a second-look procedure at 12 months or to disease progression if it occurred earlier. A positive interval laparoscopy was predictive of disease in 91% of patients, whereas a negative interval laparoscopy showed absence of disease at second look in only 70.5% of patients. A positive laparoscopic biopsy at six months showed presence of disease at second look procedure in 100% (11 of 11) of patients. It is concluded that either an intensive initial chemotherapy or change in therapy such as intraperitoneal chemotherapy after positive interval laparoscopy is indicated in future studies.
