Description of intervention(s) / exposure
This study is an observational study which aims to utilise validated assessment tools for patients undergoing VMAT radiation for skin field cancerisation of the lower limbs to explore factors which may impact oedema and lymphatic drainage. Assessments include medical history, circumferential limb measures, cone beam computed tomography (CBCT) volume measures, radiation dosimetry, bioimpedance spectroscopy, indocyanine green (ICG) lymphography and patient reported outcome surveys. Participants will attend 2 ICG lymphography scans pre radiation therapy and 6 months after completing radiation therapy which will take approximately one hour. During treatment the participants will be seen after their radiation therapy weekly for circumferential and bioimpedance spectroscopy measures and to complete patient reported outcome surveys which will take approximately half an hour. After treatment is completed the participants will be seen for the same measures and surveys one, two and six weeks, and three and six months post treatment after consultation with their radiation oncologist.

Timepoint [1] 328846 0
Pre-treatment, after 5, 10, 15, 20 and 25 fractions, weekly during treatment break, 1, 2 and 6 weeks post treatment, 3 and 6 months post treatment.
Secondary outcome [1] 400628 0
Lymphoedema severity ascertained by indocyanine green (ICG) lymphography using MD Anderson Cancer Center (MDACC) lymphoedema staging scale.
Timepoint [1] 400628 0
Baseline and 6 months post treatment
Secondary outcome [2] 400629 0
Below knee limb volume calculated by cone beam computed tomography (CBCT) and circumference measures (4cm and 10cm increments)
Timepoint [2] 400629 0
Baseline and after 5, 10, 15, 20 and 25 fractions
Secondary outcome [3] 400630 0
To determine the percent limb volume change which will reduce PTV coverage of D98% to <95% assessed using cone beam computed tomography (CBCT) scans merged with the original planning computed tomography (CT) scans in the treatment planning system. Limb volume will be calculated from circumferential measures and recorded in the electronic data management system. These volume measures will be correlated to PTV coverage.
Timepoint [3] 400630 0
PTV coverage and limb volume will be calculated after 5, 10, 15, 20 and 25 fractions
Secondary outcome [4] 400631 0
Limb volume calculated from circumferential measures

Timepoint [4] 400631 0
Limb volume calculated by circumferential limb measurements will be recorded pre-treatment, after 5, 10, 15, 20 and 25 fractions, weekly during radiation therapy treatment break, 1, 2 and 6 weeks post radiation therapy treatment, 3 and 6 months post radiation therapy treatment.
Secondary outcome [5] 400632 0
Patient reported outcomes determined by Lymphoedema Symptom Intensity and Distress Survey (leg) (LSIDS-leg) survey. LSIDS-leg surveys will be collected by research staff and recorded in the electronic data management system.
Timepoint [5] 400632 0
LSIDS-leg surveys will be recorded at baseline, end of radiation therapy treatment break, end of radiation therapy treatment, 3 and 6 months post radiation therapy treatment
Secondary outcome [6] 402340 0
Patient reported outcomes determined by Lower Limb Core Scale (LLCS) survey. LLCS surveys will be collected by research staff and recorded in the electronic data management system.
Timepoint [6] 402340 0
Lower Limb Core Scale (LLCS) recorded at baseline, after 5, 10, 15, 20 and 25 fractions, weekly during radiation therapy treatment break, 1, 2 and 6 weeks post radiation therapy treatment, 3 and 6 months post radiation therapy treatment.
Secondary outcome [7] 402341 0
Patient reported outcomes determined by the Rapid Assessment of Physical Activity (RAPA) survey. RAPA surveys will be collected by research staff and recorded in the electronic data management system.
Timepoint [7] 402341 0
The RAPA survey will be recorded at baseline, end of treatment and 6 months post treatment
Secondary outcome [8] 403133 0
Bioimpedance spectrocopy (BIS) measured using the ImediMed SOZO® device
Timepoint [8] 403133 0
BIS measurements will be recorded pre-treatment, after 5, 10, 15, 20 and 25 fractions, weekly during radiation therapy treatment break, 1, 2 and 6 weeks post radiation therapy treatment, 3 and 6 months post radiation therapy treatment.

Statistical methods / analysis
Pilot studies are designed to provide preliminary evidence on the feasibility (rather than statistical significance) of methods and procedures which can then be followed up with larger trials. There is little published guidance on sample size required for pilot studies. For this study a sample size of 10 has been decided to allow accuracy while taking into consideration budget, participant recruitment and time constraints.
The sampled patient population will be characterised by the summary demographic data.
The primary endpoint of weekly limb volume changes will be analysed with several methods. Graph the observed mean, and 95% CI over time, box plots of limb volume at key time points, scatterplots of limb volume and linear or curvi-linear regression of volume change.
MDACC lymphoedema staging will be formed into 2 categories to facilitate tabulation and logistic regression,
Volume assessments and the relationship between percent limb volume change and L-Dex score will be analysed with scatterplots, fit linear or curvi-linear regression as appropriate. In addition volume assessments further analysed to look at the differences between the means using analysis of variance (ANOVA).
PRO’s will be analysed over time with a mixed model for repeated measurements (MMRM).
