Objective: To elucidate the impact of clinical-pathological factors on Overall Survival (OS) in patients who got pregnant after breast cancer treatment. Methods: Retrospective cohort of women age younger than 40 years with breast cancer history without active disease at diagnosis of pos cancer pregnancy. Clinical-pathological factors were analyzed by age group and recent birth. Overall Survival (OS) was evaluated from Kaplan-Meier method. The association between clinical-pathological factors and OS was examined using Cox proportional hazards method to estimate Hazard Ratio (HR) with 95% Confidence Intervals (CI). Results: A total of 14 patients were selected. Median age was 28.5 years (inter quartile range, 26-35). Locally advanced stage (IIB-IIIB) was diagnosed in 64.3%. Patients lower than 35 years experienced more positive clinical lymph nodes (72.7%), grade 2 (63.6%) and ER/Pg R-negative tumors (54.5% and 72.7%, respectively). The patients with ER-positive tumors showed an improvement nonsignificant at 5-year OS (87%; p=0.097). In the bivariate analysis, patients with a higher number of pathological lymph nodes (pNs) had a 12% increase in the risk of death than those with lower number (HR=1.12; 95% CI: 1.02 to 1.2). The multivariate model (after adjustment for number of pNs, age and tumor size) as certained that the nodal status was the only independent predictor associated to a worse OS (HR=1.15; 95% CI: 1.01 to 1.3). Conclusion: Pregnancy after cancer did not have a detrimental effect on survival. The patients <35 years old group showed more unfavorable tumor features at diagnosis, which can largely explain a poorer prognosis. Nodal status was the most important prognostic factor that predicted the poor prognosis.
