title: Diagnostic open laparoscopy in the management of advanced ovarian cancer.
abstract: OBJECTIVE
  Optimal primary cytoreductive surgery (OPCS) plus adjuvant chemotherapy (AC) represents the standard management for patients with advanced ovarian cancer (AOC). Recently, some authors have suggested the use of neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) in patients with unresectable AOC. This study has been started to evaluate the role of diagnostic open laparoscopy (DOL) in predicting who are the best candidates to OPCS.
  
  
  METHODS
  All patients newly diagnosed as affected by AOC were submitted to DOL in order to establish the possibility of OPCS considered as no residual tumor left after operation. Patients considered not susceptible of OPCS were submitted to three cycles of NACT, administered every 3 weeks (Carboplatin, targeted AUC = 6, plus paclitaxel 175 mg/mq), followed by IDS and adjuvant chemotherapy.
  
  
  RESULTS
  From January 2000 to March 2004, 87 patients with AOC underwent DOL. Fifty-three patients (61%) were judged operable and therefore submitted to primary cytoreductive surgery (Group A). Optimal debulking rate in this group of patients was 96%. Thirty-four patients were judged affected by disease not cytoriducible to absent residual tumor and therefore scheduled for NACT-IDS-AC (Group B). Twenty-five patients were judged with partial clinical response and were therefore scheduled for IDS and AC. Optimal debulking rate (no residual tumor ) in Group B patients was 80%. No major perioperative complications, due to laparoscopy, occurred. All Group B patients received the first cycle of chemotherapy the day after DOL. In 34 patients (39%), an explorative laparotomy was avoided. With a median follow-up of 22 months (range 2-49 months), the proportions surviving were 87% and 60% in Group A and Group B patients, respectively.
  
  
  CONCLUSIONS
  DOL could be considered a valid diagnostic tool in evaluating the extent of disease in AOC. Our data suggest that the use of DOL leads to decrease the rate of primary cytoreductive surgery for AOC; on the other hand, a higher optimal debulking rate (no residual tumor) at primary surgery is achieved.
