Evaluation of the role of second-look surgery in ovarian cancer.

The role of second-look surgery in the management of patients with ovarian cancer has come under question. One hundred one patients have undergone the operation at Yale University over the last decade. Of 67 who had epithelial ovarian cancer, 43% had positive and 57% had negative second-look surgery. Multivariate analysis revealed that stage was a significant prognostic factor with regard to second-look surgery findings, as well as absolute and disease-free survival. We found initial tumor size and results of cytology at second-look surgery to be prognostic factors with regard to survival after a positive second-look surgery. Survival after negative second-look surgery was significantly greater than that after a positive operation. However, no improvement in survival accrued to the group of advanced-stage, platinum-treated patients who underwent second-look surgery, compared with a similar group of patients who were eligible but did not undergo the procedure. We conclude that second-look surgery in epithelial ovarian cancer patients should be limited to experimental protocol situations in which precise measurement of tumor size may be important. In ovarian germ cell malignancies, second-look surgery, in the absence of tumor markers, can be justified.
