Objective: Proper exercise immediately after breast cancer surgery (BCS) may prevent unnecessary physical and psychological decline resulting from the surgery; however, patients' attitude, barriers and facilitators for exercise during this period have not been studied. Hence, this study aims to explore the barriers and facilitators of exercise among patients with breast cancer through multiple interviews immediately after surgery through 4 weeks after BCS.
Methods: We conducted three in-depth interviews of 33 patients with breast cancer within 1 month after BCS.
Purpose: This study aimed to identify the association between Ki-67 level and the prognosis of patients with breast cancer, regardless of the timing of Ki-67 testing (using preoperative biopsy vs. postoperative specimen).
Methods: A total of 4177 patients underwent surgery between January 2008 and December 2016.
This study aimed to determine whether post-mastectomy radiotherapy (PMRT) is beneficial for the prognosis of patients who achieved pathologic complete response (pCR), or who had minimal residual disease, after undergoing neoadjuvant chemotherapy (NAC). Patients who underwent a total mastectomy between 2006 and 2018, after NAC, were included. Patients who did not receive PMRT were matched using 1:3 propensity score matching (PSM).

We investigated the clinicopathologic parameters including Ki-67 labelling index (LI) to identify factors affecting late distant recurrence (DR). Women with ER-positive breast cancer who were free of DR for 5 years were identified between January 2004 and December 2009.

This study aimed to investigate the prevalence of MPCs and to evaluate the implications of MPCs on the survival of breast cancer patients.
Materials And Methods: A total of 8204 patients who underwent surgery at Severance Hospital between 1990 and 2012 were retrospectively selected.
