| Abstract |
Routine treatment of clinically uninvolved internal mammary nodes in breast cancer patients requiring post-mastectomy radiation therapy is controversial. The purpose of this study was to measure the incidental radiation dose to the internal mammary lymph nodes not included in the planning target volume (PTV) in women with breast cancer receiving post-mastectomy radiation therapy. This retrospective protocol utilized CT-based 3D conformal treatment plans. Fifty consecutive patients were included in the analysis: 25 left breast and 25 right breast patients. 3D conformal treatment plans chest wall tangent fields and matched supraclavicular were used. All plans were prescribed to a total dose of 50 Gy in 25 fractions to the chest wall and 46 Gy in 23 fractions to the supraclavicular field. The internal mammary node chain was intentionally not included in the target volume. For purposes of this study, internal mammary vessels were contoured following the Radiation Therapy Oncologist Group atlas with a 7-mm PTV expansion, utilizing original CT simulation images. The internal mammary nodes were contoured in between the first 3 and first 5 intercostal spaces for comparison. Percent volume of internal mammary node PTV receiving 95 % of the prescribed dose (47.5 Gy) with 7-mm expansion and first 5 intercostal spaces for all patients was 25.2 % (range 0.04-97.6 %, standard deviation (SD) 23.5). The mean internal mammary node dose for all patients was 24.98 Gy (range 3.54-55.93 Gy, SD 16). Results of this study suggest the incidental dose to the internal mammary nodes does not achieve clinically significant therapeutic levels in post-mastectomy breast cancer patients treated with standard 3D conformal radiation therapy chest wall irradiation. If risk factors for microscopic involvement are present, internal mammary nodes must be specifically included in target volumes in order to be adequately treated. |

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 19 August 2015.
All research outputs
#15,683,389
of 23,305,591 outputs
Outputs from Breast Cancer Research and Treatment
#3,343
of 4,707 outputs
Outputs of similar age
#158,508
of 265,421 outputs
Outputs of similar age from Breast Cancer Research and Treatment
#54
of 76 outputs
Altmetric has tracked 23,305,591 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,707 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.2. This one is in the 23rd percentile – i.e., 23% 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 265,421 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 76 others from the same source and published within six weeks on either side of this one. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
