Lymphedema Evaluation After Adjuvant Hypofractionated Radiotherapy for 1-2 Macrometastatic Sentinel Lymph Nodes (AXILL-ART)

March 19, 2024 updated by: European Institute of Oncology

AXILL-ART: Lymphedema Evaluation After Adjuvant Hypofractionated Radiotherapy for 1-2 Macrometastatic Sentinel Lymph Nodes Without Axillary Dissection in Breast Cancer Conservative Surgery: Observational Study

In this observational prospective studi patients with invasive breast cancer no more than 5 cm and clinically node negative, scheduled for conservative surgery and Sentinel Node Biopsy (SNB), are enrolled in the protocol if they have 1-2 sentinel lymphnodes (SLNs) with macrometastases. SLN status will be checked on definitive sections.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In recent years, breast oncologic surgery has aimed to omit axillary dissection in cases where no more than two sentinel lymph nodes are positive, particularly when complementary radiotherapy to the whole breast is planned.

Radiation therapy to the axillary lymph nodes ensures excellent locoregional control in patients with primary tumor no more than 5 centimeter and 1-2 macrometastatic sentinel lymph nodes, and appears to carry fewer side effects than axillary dissection.

Arm lymphedema is indeed one of the most well-known long-term complications of breast cancer treatment, impacting the quality of life for patients undergoing lymphadenectomy. In this scenario, the study proposes a treatment of hypofractionated intensity-modulated radiotherapy (IMRT) to the breast and axillary lymph nodes with the aim of further containing the risk of developing ipsilateral arm lymphedema. IMRT improves the dosimetric profile of surrounding organs at risk in the treated area, with better dose conformity to the target volume compared to tangential fields used in conventional 3D conformal techniques (as employed in most trials described so far).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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
Percentage of patients with arm lymphedema
Time Frame: 1 year
Incidence of ipsilateral arm lymphedema 1 year after the completion of adjuvant radiotherapy
1 year

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.
