TLDR
Overall, the 5-year local recurrence rate after BCT was low, but varied by subtype as approximated using ER, PR, and HER-2 status, which may be useful in counseling patients about their anticipated outcome after B CT.Abstract:
Purpose To determine whether breast cancer subtype is associated with outcome after breast-conserving therapy (BCT) consisting of lumpectomy and radiation therapy. Patients and Methods We studied 793 consecutive patients with invasive breast cancer who received BCT from July 1998 to December 2001. Among them, 97% had pathologically negative margins of resection, and 90% received adjuvant systemic therapy. No patient received adjuvant trastuzumab. Receptor status was used to approximate subtype: estrogen receptor (ER) or progesterone receptor (PR) positive and human epidermal growth factor receptor 2 negative = luminal A; ER+ or PR+ and HER-2+ = luminal B; ER–and PR –and HER-2+ = HER-2; and ER–and PR –and HER-2–= basal. Competing risks methodology was used to analyze time to local recurrence and distant metastases. Results Median follow-up was 70 months. The overall 5-year cumulative incidence of local recurrence was 1.8% (95% CI, 1.0 to 3.1); 0.8% (0.3, 2.2) for luminal A, 1.5% (0.2, 10) for luminal B, 8....read more

TL;DR: The triple negative subtype has the worst overall and disease free survival and efforts should be directed at standardization of current testing methods and development of more reliable and reproducible testing.

Triple-negative breast cancer—current status and future directions
TL;DR: Triple-negative breast cancer is defined by a lack of expression of both estrogen and progesterone receptor as well as human epidermal growth factor receptor 2, characterized by distinct molecular, histological and clinical features including a particularly unfavorable prognosis despite increased sensitivity to standard cytotoxic chemotherapy regimens.

TL;DR: Survival analyses on a subcohort of patients with locally advanced breast cancer uniformly treated in a prospective study showed significantly different outcomes for the patients belonging to the various groups, including a poor prognosis for the basal-like subtype and a significant difference in outcome for the two estrogen receptor-positive groups.
