Effectiveness of Complex Decongestive Therapy for the Treatment of Lymphedema in Breast Cancer Patients Who Received Lymphovenous Anastomosis Surgery: a Pilot Study

Breast cancer is the most common type of cancer in women worldwide. Advances in treatment have increased survival rates, so patients must live with the complications resulting from the cancer and its treatment. One of the most common side effects is lymphedema, which can occur as a secondary effect of surgical or radiotherapy treatment. Lymphatic edema is a condition characterized by an excess of lymphatic fluid, rich in proteins, in the subcutaneous tissue, causing pain, a feeling of heaviness in the affected limb, restricted range of motion, and, in some cases, progressing to the formation of ulcers and recurrent infections; inevitably affecting the quality of life of the women who suffer from it. There are various therapeutic strategies to reduce the risk of developing lymphedema or to treat it. Among the management options is complex decongestive therapy (CDT), which is a conservative treatment that includes manual lymphatic drainage (MLD), compression therapy, skin care, and lymph-reducing exercises (LRE). Surgical options include lymph node transfer and lymphovenous anastomosis; redirecting lymphatic circulation and reducing edema in the affected limb. This is why the current research is undertaken, aiming to evaluate the effectiveness of combining these two treatment approaches in terms of reducing lymphedema, the presence of cellulitis, and changes in patients' quality of life

Detailed Description

Breast cancer is the most common type of cancer among women, with an estimated 2.3 million new cases diagnosed worldwide in 2020, with especially high incidence in developed countries. The five-year survival rate for breast cancer exceeds 90%, and the average ten-year survival rate for women with non-metastatic invasive breast cancer is 84% (Ferlay et al., 2021).

As a consequence, there is an increasing number of women facing early and late side effects from breast cancer treatment. One of the most common side effects is lymphedema, with a reported incidence after cancer treatment around 30% (Martínez Jaimez, 2017). In Colombia, it is estimated that 28% of women who undergo lymphadenectomy develop lymphedema (Valencia Legarda et al., 2020). Lymphedema is a chronic inflammatory disease that affects approximately 250 million people worldwide, mostly associated with cancer treatment. It can occur as a result of breast cancer surgery and/or radiotherapy (Riady-Aleuy et al., 2022). Lymphedema is defined as the accumulation of protein-rich fluid in the interstitium, secondary to abnormalities in the lymphatic transport system.

According to the impact of lymphedema on the quality of life of individuals, as well as the associated social and economic costs, efforts must be made to prevent and treat it. Various conservative strategies are used to reduce the risk of developing lymphedema and to manage it once it has developed. Among the physiotherapeutic options is complex decongestive therapy (CDT), which is a conservative treatment that includes manual lymphatic drainage (MLD), compression therapy (consisting of compression bandages, compression sleeves, or other types of compression garments), skin care, and lymph-reducing exercises (LRE).

Another treatment option is surgery, which has traditionally been considered a last resort when conservative measures have failed. However, increasingly advanced surgical interventions are now being performed early in the disease process, with the hope of preventing or reversing edema that arises from impaired lymphatic flow (Markkula et al., 2019). These interventions include liposuction, lymph node transfer, and lymphaticovenular anastomosis (LVA). The latter was first described in 1960, but it wasn't until 1989 in Japan and in 2020 in Colombia that it became the gold standard of microsurgery, emerging as an innovative technique in our field, increasingly used as a treatment for lymphedema rather than as a last-resort strategy when other treatments have failed (Gupta et al., 2021).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Lymphedema change
Time Frame: Baseline, post-intervention up to 3 weeks and 3 months follow up
Upper and leg Extremity Lymphedema Index. The index includes 5 perimeters that are sum and divided by BMI. Classified as mild leg lymphedema < 250, mild to severe 250-350 and severe > 350. Classified as mild arm lymphedema < 130, mild to severe 130-150 and severe > 150 This outcome is compound by multiple measurements that will be aggregated to arrive at one reported.
Baseline, post-intervention up to 3 weeks and 3 months follow up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quality of life change
Time Frame: Baseline, post-intervention up to 3 weeks and 3 months follow up
ARM and LEG Lymphoedema Quality of Life Tool (LYMQOL). It includes 3 domains (Function, symptoms, mood) and an overall quality of life score. Domain totals are calculated by adding the individual scores and dividing the total by the number of questions answered. A higher number means a poor quality of life.
Baseline, post-intervention up to 3 weeks and 3 months follow up
