Patients were then screened for further pregnancy. Clinicopathologic variables, oncologic outcomes, and pregnancy outcomes were recorded. The Chi-square test and t-test were used to compare patients with subsequent pregnancy with those without. Kaplan\u2013Meier method and log-rank test were used to estimate 5-year disease-free survival (DFS).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Overall, 75 patients with PABC were identified, 58 of whom had PABC and no further pregnancies (NSP-PABC) and 17 with subsequent pregnancy (SP-PABC). Compared with patients with NSP-PABC, patients with SP-PABC were significantly younger (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.015) and less likely to have prior pregnancies (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001). Overall median follow-up was 4.3 years. Calculated 5-year DFS rates were 86.2% and 89.0% for the SP-PABC and NSP-PABC groups, respectively (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.76). Calculated 5-year overall survival was 100% and 90.7% for the SP-PABC and NSP-PABC groups, respectively (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.22).
