Background: Triple-negative breast cancer (TNBC) is a subtype of breast cancer with stronger invasive capacity. For the operation strategies of early staged (stage I and stage II) TNBC patients, BCS plus radiotherapy (BCS+RT), mastectomy only (MRM only) or MRM plus radiotherapy (MRM+RT) is feasible, but no clear conclusion has been made on the choice of these treatments. Methods: The early staged TNBC patients (stage I and stage II) from the Surveillance, Epidemiology and End Results (SEER) program database between 1973 and 2014 were included in the study. ⋯ After we performed propensity score weighting and integrated the weights for each covariate in the multivariate cox proportional model. BCS+RT remained to be prognostic beneficial compared to the other treatment options (P < 0.001). Conclusion: BCS+RT demonstrated better prognosis than MRM only and MRM+RT treatments for early-staged TNBC patients.
