title: A review of second-look laparotomy for ovarian cancer.
abstract: One hundred twenty-seven patients underwent second-look laparotomies from July 1969 to June 1982. To be included in this report they must have met the following criteria: a documented ovarian neoplasm; previous surgery; adequate chemotherapy for cessation if no disease was found; and no X-ray, chemical, or clinical evidence of disease including an exam under anesthesia. Forty-one percent had residual disease at second-look laparotomy. The original stage and the percentage of tumor debulked at initial surgery were inversely related to the likelihood of finding residual disease. Age, histologic type and grade, and type of chemotherapy did not show a significant relationship with the likelihood of disease persisting. Recurrent tumor was subsequently detected in 16% of patients who had been found to be free of disease at second-look laparotomy. Of thirty stage III and IV patients treated with combinations containing cis-platinum, 10 (33%) had recurrences. This rate of recurrence was significantly greater than the 17.6% recurrence rate in 17 patients with Stage III and IV disease whose chemotherapy consisted of single alkylating agents or with combinations without cis-platinum. Twenty patients underwent a third-look laparotomy after completion of additional chemotherapy. Nine were found to have no residual disease. Two of the nine (22%) subsequently had recurrence of disease. Three of the eleven patients with persistent disease at the time of a third-look laparotomy underwent a fourth-look laparotomy. All were found free of disease and none have recurred. Six (55%) of those with persistent disease at the third-look laparotomy have died despite continued therapy. The ability to successfully treat some patients with persistent disease continues to be a justification for the use of a second-look laparotomy. However, the high rate of recurrence after cessation of treatment following the finding of no residual disease raises the question of whether it is appropriate to discontinue all therapy at this time.
