The role of second-look laparotomy in the long-term survival in ovarian cancer

To elucidate the role of second-look laparotomy in the management of ovarian cancer patients, were retrospectively reviewed our experience with this procedure in epithelial ovarian cancer patients.

The hospital records of 617 patients with advanced ovarian cancer were reviewed. The 308 patients who underwent second-look laparotomy were followed from four to 18 years with a median follow-up of 12 years after start of primary chemotherapy.

Patients who achieved pathological complete response (PCR), microscopic partial response (PPR mic.), macroscopic partial response (PPR mac.), stable disease (PSD), and progressive disease (PPD) at second-look laparotomy had a median survival time of 149, 39.5, 24, 14, and eight months, respectively. Secondary surgical cytoreduction could be performed only in 101 patients with macroscopic persistent disease. The group of all patients with secondary tumor debulking had no survival advantage compared with the group of patients with PPR mac., PSD, and PPD, unable to have secondary cytoreduction. Patients left with no tumor after second-look laparotomy did not survive as long as patients who achieved PCR and PPR mic. at second-look laparotomy. Factors prolonging survival after second-look laparotomy included younger age, good pre-treatment performance status, smaller primary residual tumor size, longer interval between start of chemotherapy and second-look laparotomy, and the pathologically proven CR or PR mic.

Second-look laparotomy appears to have a minor role in the routine management of ovarian cancer patients, especially in the context of the limited effectiveness of second-line therapy. This procedure should be limited to clinical treatment protocols to determine effectiveness of new agents.
