Effect of airplane travel on women treated for breast cancer.

Abstract
Abstract Abstract #1119 Background: Many patient materials promulgate lifestyle adaptations purported to minimize risk of lymphedema. One factor often mentioned is development or exacerbation of lymphedema due to airplane travel. The aim of this study was to describe prospectively the effect of airplane travel on women treated for breast cancer, traveling to Caloundra, Qld., Australia to attend a dragon boat regatta.
 Methods: Pre and post data were obtained from 63 women traveling from Canada to Australia, and from 12 women traveling within Australia. 54% were treated for breast cancer on their dominant side, 63% underwent mastectomy with or without reconstruction, 77% underwent axillary node dissection, and 21% wore a compression sleeve during flight; 94% trained at a moderate to vigorous intensity for the regatta. Single frequency bioimpedance analysis (BIA; XCA; Impedimed Inc.®) was used to determine the inter-limb difference in upper limb extracellular fluid. BIA is highly reliable and has high sensitivity and specificity for increased extracellular fluid accumulation. Change in ratio >0.05 for women without lymphoedema is of clinical significance. Women were measured within 2 weeks of their flight to Caloundra, immediately on arrival in Caloundra, and for 46 women, within 6 weeks of return to Canada.
 Results: Airplane travel did not have a significant effect on the upper limb BIA ratio, either between the pre and post flight (t75= -0.355; p=0.72) or between the pre and follow-up measures (t44=.241; p=0.811).
 
 Overall, the BIA post ratio increased from the pre measure by ≤0.02 in 48 women; 0.02 to <0.05 in 12 women; 0.05 to <0.10 in 10 women; and >0.10 in 5 women (Fig 1). In Figure 1, symbols in grey-shaded area represents women who did not have lymphedema prior to flight but presented with it post flight and the dashed lines indicate previously established cut-offs for criteria for detection of lymphedema. Dotted line on each graph is the line of agreement. The 6 symbols in the grey shaded area (Fig 1) represent women from the international group; their change in BIA ranged from 0.05 to 0.28. Follow-up measures were available on 5 of these women, and indicated that 4 were below the cut-offs for lymphedema. All 6 women had undergone mastectomy and axillary clearance of their lymph nodes and for 5, surgery was on their dominant side. Only 3 of the women wore a compressive sleeve on the plane.
 Discussion: For the majority of women who undertake moderate to vigorous upper limb exercise, airplane travel did not have a significant impact on extracellular fluid ratio. Acknowledgment: Impedimed for funding and equipment. Citation Information: Cancer Res 2009;69(2 Suppl):Abstract nr 1119.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
