Lymphoedema Prevention Following Inguinal or Ilioinguinal Dissection for Metastatic Melanoma
Scientific title

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Thigh length, 20-30mmHg compression garments on the leg of the operative side, and medical grade compression shorts will be worn approximately 12 hours a day and removed for hygienne and sleeping. The specific garment utilised will depend on the individual patient measurements regarding best fit and fabric characteristics so may include garments from Sigvaris, Jobst, Juzo or if required, even be custom made. Unless medical co-morbidities dictate caution, all leg garments will be 20-30mmHg. All garments will be applied following removal of post operative drains.
Simple, or self lymphatic drainage (SLD) will be taught to participants in the intervention group by trained lymphoedema therapists. They will be provided an individual body map and drainage pathway and guidelines. They will receive three half hour formal 1:1 education sessions regarding self lymphatic drainage and are asked to conduct this each day for 6 months following post operative removal of drains. Training and education regarding correct garment donning and doffing of garments will occur at initial fitting with trained lymphoedema therapists ensuring that the participant (or carer) are able to correctly and safely apply and remove the garments. Drainage techniques and garment wear will continue to be assessed and monitored throughout the 6 month intervention phase.

Comparator / control treatment
Control group participants will be monitored via 3 monthly assessment (bioimpedence, circumferential and quality of life). If signs of lymphoedema arise, they will be offered comprehensive lymphoedema treatment. This is standard treatment.

Outcomes
Primary outcome [1] 279883 0
Reduction in the rate of lymphoedema of 45% to 18% with statistical significance of p = 0.05. Allowing for a 33% two year mortality and 10% attrition a total of 155 participants need to be recruited to the study in order to achieve a sample of size of 88.
There is no worldwide consensus regarding quanitification of lymphoedema and this creates problems for classifying lymphoedema.
For the purpose of this study, our team have defined lymphoedema as a volume change of greater than 10% compared to the unaffected limb in addition to a bioimpedance change of 10 points from pre-operative baseline. The International Society of Lymphology defines "mild" lymphoedema as less than a 20% volume change.
Circumferential tape measurements at 10cm intervals (using a measuring board) will be taken of the operated side and contralateral leg. In addition, bioimpedence analysis will also be taken.
Quality of Life self rating scales (EORTC and the LYMQOL-leg) will also be utilised.
Assessments will be conducted by a blinded assessor pre-operatively, at 6 weeks post operatively and then at 3 monthly intervals for 2 years following surgery.
Timepoint [1] 279883 0
At two years after randomisation
Secondary outcome [1] 294673 0
Reduction in severity of lymphoedema between groups.

This will be quantified by the volume of lymphoedema measured using both circumferential measures to calculate volume and using bioimpedence measures.

LYMQOL-leg is a self-rating questionaire asking patients to quantify their perception of how lymphoedema is impacting on their life and function.

At two years after randomisation
Secondary outcome [2] 294841 0
Assess quality of life for all patients.

EORTC and the LYMQOL (leg) will be administered to control and intervention groups to assess quality of life.
Timepoint [2] 294841 0
At two years after randomisation
Secondary outcome [3] 294843 0
Assessing the impact of the following in development of lymphoedema (seroma, wound complications, co-morbidities, BMI, adjuvant radiotherapy).


Whilst evidence exists to support that increased BMI and radiotherapy may negatively impact on development of lymphoedema, we wish to analyse whether the number of pre-existing co-morbidities OR wound complications further contribue to lymphoedema development.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Concealed allocation by sealed envelopes.

Eligible participants will be identified by research nurse at time of booking for surgery in both public and private consulting rooms. Interested and eligible participants will be provided with written information and offered to sign consent to be recruited into the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomised control trial via Mater Reseach Support Centre randomisation generated envelopes.
Computer generated randomised variable permuted block concealed allocation.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Any participant on the control arm of the study who develops lymphoedema will be offered intervention and may therefore there may be some participants will crossover from control to intervention.

Type of endpoint/s
Efficacy
Statistical methods / analysis
Baseline demographic characteristics of the control and intervention gorups will be reported; continuous variables using mean and standard deviation (SD) or median and interquartile range (IQR), depedent on whether the variable is normally distributed, as assessed by the Shapiro-Wilk test and the visual confirmation using histograms) and the frequencies and proportions for categorical variables. Primary outcome will be compared between the two groups using the difference of proportions, and will be presented as the absolute difference, corresponding 95% confidence interval (CI) and p-value; an intention to treat analysis will be used. Continuous secondary outcome measures will be assessed for differences between the control and intervention groups by reporting the mean (SD) or median (IQR) and associated 95% CI's; categorical secondary outcome measures will be treated similar to the priamry outcome. As the study is not powered to detect differences in the secondary outcome measures p-values will not be presented. To determine if there are factors that affect development of lymphoedema multivariate logistic regresssion will be undertaken including possible independent predictors (such as BMI, medical complications) that were identified as significant through bivariate analysis.
