Purpose Information on tubular carcinoma (TC) of breast is limited due to its rarity. A multi-institutional study was performed to investigate the prognosis and failure patterns of TC compared to invasive ductal carcinoma (IDC). Materials and methods We collected retrospective data on 205 patients with TC from eleven institutions. For each TC case, 3 cases with IDC were matched according to similar size, t-stage, and n-stage from the same institution. Patterns of failure, disease free survival (DFS) and overall survival (OS) were assessed and compared between the groups. Results DFS at 5 years was 98.8% and 97.3% and OS at 5 years was 99.5% and 99.6% in TC and IDC, respectively. Among the patients with TC, 5 patients (2.4%) developed contralateral breast cancer, while 3 patients (0.5%) presented with contralateral breast cancer in patients with IDC. Conclusions The TC of breast presents an excellent prognosis, but the contralateral breast cancer tends to be more frequently observed compared to IDC in Korean women.
