概要:

application/pdf<br />Journal Article<br />Background& Aims: True local recurrences(TR)and new primary tumors(NP)in the conserved breast\nafter breast-conserving surgery with radiation therapy are determined by the initial su … rgical margin, the\nlocation of recurrent tumors and the histological consistency between initial tumors and recurrent tumors.\nMethods: A total of 15 patients with breast recurrence out of a group of 389 women with breast cancer\nwho underwent breast-conserving therapy between 1991 and 2003 were included in this study. The\nbiological differences between TR and NP were examined. Results: Eight patients had TR, and seven\nhad NP. The disease-free interval was 34.6 months in the TR group and 94.1 in the NP group.\nBreast-free survival was significantly better in the NP group than the TR group. The accumulated\n10-year overall survival after salvage surgery in patients with TR or NP tumors was 85.1％. The\naccumulated overall survival after salvage surgery was better in the NP group than the TR group.\nConclusions: Patients with NP tumors have a favorable prognosis compared to those with TR tumors.\nIt is important to determine the type of breast recurrence in order to accurately predict the prognosis of\npatients with breast recurrence. 続きを見る
