title: Surgical second look in ovarian cancer: a randomized study in patients with laparoscopic complete remission--a Northeastern Oncology Cooperative Group-Ovarian Cancer Cooperative Group Study.
abstract: OBJECTIVE
  The usefulness of extensive and repetitive surgery for patients with ovarian cancer still remains unproven (at least for some conditions). We planned an accurate prospective test of the hypothesis that patients with advanced-stage disease, after they had reached a clinical complete remission (CR), may benefit from surgical second look (SSL).
  
  
  METHODS
  One hundred two patients in CR (as assessed by clinical findings, markers, and visualization by computed tomographic [CT] scan and laparoscopy), after initial debulking and first-line chemotherapy, were randomized to two arms, which were well balanced for predictive criteria such as age, stage at presentation, histology, grading, date of randomization, and residua after first surgery. Forty-eight patients were randomly assigned to receive follow-up evaluation only, while 54 were assigned to receive second surgery (eight of them refused). Of 46 surgical patients, 35 had negative and 11 positive surgical findings (24% clinically false-negative).
  
  
  RESULTS
  Despite the microscopic residua found at open surgery, and the fact that the patients were then treated with second-line chemotherapy, SSL did not increase the probability of survival in this setting. In an analysis of the results according to the intention-to-treat criteria, after a 60-month follow-up period, the overall survival rates in the two groups of patients (SSL v no SSL) were 65% and 78%, respectively (P = .14). Multivariate analysis according to predictive criteria confirmed there was no significant difference between the two groups (P = .39).
  
  
  CONCLUSIONS
  Our study shows the following: (1) our second-line treatment is scarcely effective; (2) SSL accurately defines complete responders to first-line chemotherapy; (3) SSL per se does not prolong survival; and (4) if confirmed, a less invasive procedure could replace SSL as a valuable method in new first-line regimens in ovarian cancer patients with clinical CR confirmed by laparoscopy.
