| Abstract |
In pediatric Hodgkin lymphoma (HL), radiotherapy (RT)-related late toxicities are a prime concern during treatment planning. This is the first study to examine whether arm positioning (raised versus akimbo) result in differential cardiopulmonary and breast doses in patients undergoing mediastinal RT. Two treatment plans were made for each patient (akimbo/arms raised); treatment was per Children's Oncology Group AHOD0031 protocol, including AP/PA fields. The anterior midline T6-T7 disk space was used as an anatomic reference of "midline." Heart/lungs were contoured for each setup. For females, breasts were also contoured and nipple positions identified. Volumetric centers of contoured organs were defined and three-dimensional distances from "midline" were computed. Analyzed dosimetric parameters included V5 (volume receiving ≥5 Gy), V10, V15, V20, and mean dose. Statistics were performed using the Mann-Whitney test. Fifteen (6 females, 9 males) pediatric HL patients treated with mediastinal RT were analyzed. The median lateral distance from the breast center/nipple to "midline" with arms akimbo was larger than that with arms raised (8.6 vs. 7.7 cm left breast, p = 0.04; 10.7 vs. 9.2 cm left nipple, p = 0.04; 8.7 vs. 7.0 cm right breast, p = 0.004; 9.9 vs. 7.9 cm right nipple, p = 0.007). Raised arm position was associated with a median 2.8/3.0 cm decrease in breast/nipple separation, respectively. There were no significant differences in craniocaudal breast/nipple position based on arm positioning (p > 0.05). Increasing breast volume was correlated with larger arm position-related changes in breast/nipple separation (r = 0.74, p = 0.06/r = 0.85, p = 0.02). Akimbo positioning lowered median breast V5, V10, V15, and mean dose (p < 0.05), with no differences observed in patients with both mediastinal and axillary disease for any parameters (p > 0.05). Arm position had no significant effect on cardiopulmonary doses. Akimbo arm positioning may be advantageous to decrease breast doses in female pediatric HL patients undergoing mediastinal RT, especially in the absence of axillary disease. |

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 August 2016.
All research outputs
#19,945,185
of 25,374,917 outputs
Outputs from Frontiers in oncology
#9,321
of 22,416 outputs
Outputs of similar age
#282,973
of 380,100 outputs
Outputs of similar age from Frontiers in oncology
#36
of 60 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 22,416 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 49th percentile – i.e., 49% 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 380,100 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 60 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
