Zhang WW, et al. - The clinicopathologic characteristics and clinical outcomes of the mixed type vs the pure type of tubular carcinoma (TC) of the breast were assessed via this retrospective cohort study. They categorized patients into the following three groups: patients with pure TC of the breast (the PTC group), patients with TC and carcinoma in situ of the breast (the TC-CIS group), and patients with TC and other invasive carcinomas of the breast (the TC-IC group). Very low locoregional recurrence and distant metastasis rate were noted in both the pure type and mixed type of TC of the breast, and both have excellent survival. Good prognosis similar to the PTC group is expected in the TC-IC.
