| Abstract |
Administering postmastectomy radiotherapy (PMRT) to patients with T1-2 breast cancer and one to three positive axillary lymph nodes (ALNs) is controversial. The current study assessed the association of clinicopathologic features and molecular subclassification with locoregional recurrence (LRR) in patients who did not receive PMRT. Between January 2004 and December 2008, 293 patients with T1-2 breast cancer and one to three positive ALNs not receiving PMRT were analyzed. Most of the patients received an anthracycline- or taxane-based regimen or both. The patients were divided according to the four molecular subtypes as follows: luminal A/B, luminal human epidermal growth factor receptor 2 (HER2), HER2, and triple-negative breast cancer. Overall survival (OS) and LRR were calculated using the Kaplan-Meier method, and the clinicopathologic prognostic factors were compared using log-rank tests and the Cox regression model. After a median follow-up period of 82.8 months, the 10-year LRR and OS were respectively 10 %, and 88.9 %. The patients with triple-negative breast cancer had a higher 5-year LRR rate (10.6 %) than those without this disease (4.2 %) (p = 0.05). Multivariate analysis showed that young age (≤40 years), tumor larger than 3 cm, and the presence of extensive intraductal components were significant risk factors for LRR. The 5-year LRR was 3.1 % for the patients without the aforementioned risk factors, 7.9 % for those with one risk factor, and 25 % for those with two or more risk factors (p < 0.001). Administering modern systemic therapy to early breast cancer patients not receiving PMRT reduced the LRR rate. Younger patients, those with a tumor larger than 3 cm, and those with extensive intraductal components might benefit from PMRT. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 21 July 2016.
All research outputs
#18,466,238
of 22,881,154 outputs
Outputs from Annals of Surgical Oncology
#5,000
of 6,487 outputs
Outputs of similar age
#279,142
of 363,105 outputs
Outputs of similar age from Annals of Surgical Oncology
#129
of 174 outputs
Altmetric has tracked 22,881,154 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,487 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one is in the 15th percentile – i.e., 15% of its peers scored the same or lower than it.
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 363,105 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 174 others from the same source and published within six weeks on either side of this one. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
