Abstract
We reviewed the clinical and pathologic features of pure tubular carcinoma of the breast with particular emphasis on the reported risk factors associated with local recurrences and survival following breast-conserving therapy. Of 1653 cases of invasive breast cancer, 12 (0.7%) were identified as pure tubular carcinoma. Clinical/pathologic features of pure tubular carcinoma were compared with those of T1 invasive carcinoma of all other histologic types (T1 IC). Of the 12 patients with pure tubular carcinoma (median tumor diameter 1.4 cm; range 0.5–3.0 cm), a multicentric association was identified in one patient while a multifocal association was seen in two. One patient had nodal metastatic disease out of the ten who underwent axillary dissection. No lymphatic vessel invasion was identified in any tumors (P < 0.1 vs T1 IC). In addition, extensive intraductal spread was not present in any tumors (P < 0.05 vs T1 IC). This study shows that patients with pure tubular carcinoma are appropriate candidates for breast-conserving therapy based on the clinical/pathologic features. When a multifocal association is suspected preoperatively, either a wide local excision or a quadrantectomy which includes other lesions is thus recommended.
