In the univariate analyses, nulliparous women had poorer prognosis than parous women among CS patients (<jats:italic>P</jats:italic> = 0.071, log-rank test) and ESS patients (<jats:italic>P</jats:italic> = 0.15). In analyses adjusted for clinical stage and age at diagnosis, nulliparity was associated with a worse outcome in ESS patients only (hazard ratio, 0.50; 95% confidence interval, 0.22-1.12; parous vs nulliparous women); a trend with increasing number of births was also observed, of borderline significance (<jats:italic>P</jats:italic> = 0.058). No independent prognostic impact of parity was found in LS or CS patients. However, a considerably higher proportion of nulliparous than parous CS patients was diagnosed with advanced-stage disease (<jats:italic>P</jats:italic> = 0.003).</jats:p></jats:sec><jats:sec><jats:title>Conclusion:</jats:title><jats:p>Nulliparity seems to be associated with poorer prognosis in ESS patients; no independent prognostic impact of parity was seen among LS or CS patients.
