| Abstract |
The aim of our study was to analyze triple-negative (TN) breast cancer, which is defined as being negative for the estrogen receptor (ER), the progesterone receptor (PgR), and the human epidermal growth factor receptor 2 (HER-2/neu) and which represents a subset of breast cancer with different biologic behavior. We investigated the clinicopathological characteristics and prognostic indicators of lymph node-negative TN breast cancer. Medical records were reviewed from patients with node-negative breast cancer who underwent curative surgery at Grant Medical College and Sir JJ Group of Hospitals, Mumbai, India, from May 2007 to October 2010. Clinicopathological variables and clinical outcomes were evaluated. Among 683 patients included, 136 had TN breast cancer and 529 had non-TN breast cancer. TN breast cancer correlated with younger age (<35 years, P = 0.003) and a higher histopathologic and nuclear grade (P < 0.001). It also correlated with a molecular profile associated with biological aggressiveness: negative for Bcl-2 expression (P < 0.001), positive for the epidermal growth factor receptor (P = 0.003), and a high level of p53 (P < 0.001) and Ki-67 expression (P < 0.00). The relapse rates during the follow-up period (median 56.8 months) were 14.7% for TN breast cancer and 6.6% for non-TN breast cancer (P = 0.004). Relapse-free survival (RFS) was significantly shorter among patients with TN breast cancer compared with those with non-TN breast cancer: 3.5-year RFS rate 85.5% versus 94.2%, respectively; P = 0.001. On multivariate analysis, young age, close resection margin, and triple negativity were independent predictors of shorter RFS. TN breast cancer had a higher relapse rate and more aggressive clinicopathological characteristics than non-TN in node-negative breast cancer. Thus, TN breast cancer should be integrated into risk factor analysis for node-negative breast cancer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 March 2012.
All research outputs
#3,798,611
of 25,374,647 outputs
Outputs from Breast cancer targets and therapy
#52
of 324 outputs
Outputs of similar age
#17,027
of 120,084 outputs
Outputs of similar age from Breast cancer targets and therapy
#2
of 3 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 324 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one has done well, scoring higher than 83% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 120,084 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 83% of its contemporaries.
We're also able to compare this research output to 3 others from the same source and published within six weeks on either side of this one.
