Brief Summary

This is a randomized clinical trial with women with lymphedema secondary to breast cancer. The intervention will consist of the use of self-adjusting clothing versus compressive bandaging (routine treatment of the institution). Self-adjusting clothing is expected to be more effective for the treatment of lymphedema reduction, when compared to standard treatment, in addition to promoting a better quality of life and functionality.

Detailed Description

This is a randomized clinical trial, simple blind, which aims to evaluate the effectiveness of the use of self-adjusting compression garments (Read Wrap®) in reducing the volume of the upper limb of women with lymphedema secondary to breast cancer. It will be carried out in a referral hospital for the treatment of breast cancer in Brazil, with inclusion scheduled for June 2021 and follow-up of up to 1 year. All volunteers must have lymphedema in the upper limb after surgical treatment for breast cancer for more than 6 months, indicating phase 1 of compressive therapy. According to the sample calculation, 72 women will be needed to be randomly randomized in a 1: 1 ratio among the experimental intervention group (n = 36) and the standard intervention group (n = 36). The intervention consists of compressive therapy in the volume reduction phase for lymphedema secondary to breast cancer. The Experimental Intervention Group will receive an adjustable compaction wrap (Read Wrap®) while the standard Intervention Group will be submitted to compressive bandaging and will be followed up on an outpatient basis, as per institutional routine, twice a week, for 30 days. The institutional protocol for the lymphedema reduction phase will be respected, in which the orthosis is used at home for as long as possible, with time off just for bathing and sleeping, in addition, skincare and therapeutic exercises for upper limbs must be performed daily. An orientation booklet and home exercises of the institutional routine will be delivered. During the first 30 days of treatment, all study participants will be accompanied by a telephone channel that will be made available for questions, guidance, and communications of adverse events, in addition to a therapeutic diary that will be delivered at the first consultation and collected after this period, destined to notify relevant information that considers the use of compressive therapy, such as facilities, difficulties and time of use, symptoms related to the arm and adverse effects that may arise, and to monitor adherence to exercises. The suspension of treatment before the anticipated end of therapy will occur when adverse effects are observed, such as an increase in limb volume greater than 10% from the last measurement, signs of dermatitis, associated skin, or allergy. The case will be evaluated by the physiotherapy team and, when necessary, by the medical team and the treated procedures will be adopted.

Data collection will take place through the analysis of physical and electronic data, medical records, interviews, and physical examination. The interviews will be conducted through questionnaires produced by the researchers, in addition to validated questionnaires for the Brazilian population. The evaluations will take place in the outpatient clinic of the physiotherapy service of the hospital on the 1st, 7th, and 30th day of the intervention for immediate evaluation, and will be followed up to 1 year later, to verify the measures of long-term results. The analysis of the data will be descriptive and comparative of the intervention groups, about the selected variables and the main results, through the analysis of measures of central tendency, dispersion, and frequency distribution. The evaluation of the result will be carried out by intention of treatment, using linear and simple, and multiple logistic regression. For all analyzes, a 95% confidence interval will be considered.

Arm && Interventions

Group	Intervention	Description
Compression Bandage	Compression Bandage	Daily use of compression bandage on the upper limb with breast cancer-related lymphedema during phase 1 compression therapy.
Adjustable compression wrap	Adjustable Compression Wrap	Daily use of the Adjustable Compression Wrap on the upper limb with breast cancer-related lymphedema during phase 1 compression therapy.

Primary Outcome Measures

Name	Time	Method
Arm volume	Assessment of arm volume will be on the before (1st day), 30 days, 6 months and 1 year after enrollment.	The main outcome is the change in the volume of the upper limb with lymphedema, which will be assessed through the perimeter of the circumference of the limb, and indirectly estimated the volume of the limb using the cone trunk formula.

Secondary Outcome Measures

Name	Time	Method
Upper limb functionality	The evaluation of the Upper limb functionality will be before (1st day), 30 days, 6 months and 1 year after enrollment.	The functionality of the upper limbs will be assessed by the 'Disabilities of the Arm, Shoulder and Hand Questionnaire' (DASH). It is a validated instrument for our population, consisting of 30 questions that assess the ability to perform certain activities in the last week, regardless of the upper limb used. The score ranges from 0 to 100, the higher the worse the functionality.
Tissue characteristics (fibrosis) of the upper limb with lymphedema	The evaluation of the tissue characteristics of the arm will be before (1st day), 30 days, 6 months and 1 year after enrollment.	Ultrasonography is used, a non-invasive method of capturing images of tissues through the emission of ultrasonic waves, through the evaluation of images obtained by the portable device, it will be possible to characterize the alteration of the dermoepidermal complex and the tissue. subcutaneous tissue of the upper limb with lymphedema. The report will be provided by a professional with experience in using the kinesiological ultrasound method.
Tissue temperature of the upper limb with lymphedema	The tissue temperature of the arm will be before (1st day), 30 days, 6 months and 1 year after enrollment.	The tempertature of the arm will be assessed by means of thermography. Thermography is a safe, non-invasive imaging method that determines the distribution of body surface temperatures according to the physiological and pathological condition of the tissues. Inflammation, metabolic changes in the subcutaneous tissue and changes in blood supply result in changes in the temperature gradient of the affected area. In this way, the different stages of lymphedema will be related to different patterns of temperature distribution. The body surface temperatures will be recorded by means of a thermal camera and will be taken in the orthostatic position, from the anterior and posterior portions of the limb, at a distance of 2m. Later, these thermometric images will be analyzed using proprietary software. The standard measurement used will be in degrees celsius (ºC).
Health-related quality of life	The evaluation of the Health-related quality of life will be before (1st day), 30 days, 6 months and 1 year after enrollment.	Health-related quality of life will be assessed using 'European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30' (EORTC QLQ-C30). It is an instrument validated for our population, which scores from 0 to 100, the higher the value the better the quality of life will be.
Handgrip strength	The handgrip strength assessment will be before (1st day), 30 days, 6 months and 1 year after enrollment.	Hand grip strength will be assessed by the dynamometer for 3 attempts, being considered the best of the 3.
