| Abstract |
The purpose of this study was to understand the short-term therapeutic effects of an activated carbon nanoparticle-epirubicin suspension for regional lymphatic chemotherapy in patients with breast cancer. One hundred and twenty patients with stage I, II, or III primary breast cancer were randomly divided into three groups: the lymphatic chemotherapy group using the activated carbon nanoparticle-epirubicin suspension, the epirubicin control group, and the activated carbon control group. Each group of 40 patients was further divided into two subgroups with the drug injected either 24 or 48 h before surgery. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL) assay was used to determine cancer cell apoptotic indices in metastatic lymph nodes. The epirubicin concentration in the black-stained lymph nodes in the lymphatic chemotherapy treatment group was 4,144.64 ± 2,426.44 ng/g, which is significantly higher than in the epirubicin control group (335.87 ± 212.82 ng/g, P < 0.001). The plasma epirubicin concentrations at 0.5, 1.5, and 24 h postinjection in the regional lymphatic chemotherapy treatment group were significantly lower than in the epirubicin control group (P < 0.001). Tolerable mild pain was observed at the injection area after administration of the epirubicin-activated carbon nanoparticle suspension. No regional necrosis or adverse effects were found. The TUNEL assay demonstrated that there was no significant difference in the apoptotic indices in the metastatic lymph nodes from the three groups. Performing lymphatic chemotherapy by regionally injecting the epirubicin-activated carbon nanoparticle suspension could significantly enhance the drug concentration in the stained lymph nodes and lower the plasma drug concentration. The epirubicin-activated carbon nanoparticle suspension has the ability to release the drug slowly in the lymph nodes and, as a result, can prolong the chemotherapeutic effects. |

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 11 September 2012.
All research outputs
#15,251,053
of 22,678,224 outputs
Outputs from Tumor Biology
#1,049
of 2,621 outputs
Outputs of similar age
#106,931
of 169,211 outputs
Outputs of similar age from Tumor Biology
#13
of 19 outputs
Altmetric has tracked 22,678,224 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 2,621 research outputs from this source. They receive a mean Attention Score of 2.2. This one has gotten more attention than average, scoring higher than 53% 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 169,211 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 19 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
