BackgroundThe impact of intraoperative rupture on prognosis is controversial in early-stage epithelial ovarian cancer (EOC). Thus, we performed a meta-analysis to determine its impact and to evaluate factors to increase its risk.MethodsWe searched PubMed, Embase, and the Cochrane Library till May 2011, and 9 eligible studies including 2382 patients were evaluated. All patients were classified into three groups: no rupture; intraoperative rupture; preoperative involvement.ResultsPreoperative involvement decreased progression-free survival when compared with intraoperative rupture (PFS; HR, 1.47; 95% CI, 1.01–2.14), which also showed poorer PFS than no rupture (HR, 2.41; 95% CI, 1.74–3.33). Although preoperative involvement reduced PFS when compared with intraoperative rupture (HR, 2.63; 95% CI, 1.11–6.20), there was no difference in it between intraoperative rupture and no rupture in patients who underwent complete surgical staging operation and adjuvant platinum-based chemotherapy if needed (HR, 1.49; 95% CI, 0.45–4.95). Furthermore, adhesion to adjacent tissues, grade 2 or 3 disease were more common (ORs, 2.01 and 2.47; 95% CIs, 1.20–3.37 and 1.12–5.46), whereas mucinous tumor was less frequent (OR, 0.51; 95% CI, 0.37–0.72) in intraoperative rupture than in no rupture.ConclusionsIntraoperative rupture may not decrease PFS when compared with no rupture in patients with early-stage EOC who underwent complete surgical staging operation and adjuvant platinum-based chemotherapy. Furthermore, more adhesion to adjacent tissues and grade 2 or 3 disease, and less mucinous tumor are expected to increase the risk of intraoperative rupture.
