Hemopatch Versus Axillary Drainage After Axillary Lymphadenectomy
A study testing hemopatch and Aspirative drainage in people with Breast Cancer and Breast-conserving Surgery, run by Fundación para la Investigación del Hospital Clínico de Valencia at 1 site in Spain.
Trial summary
Aspirative drainage continues to be the "gold standard" for the management of this post-surgical complication, even though it can lead to complications such as obstruction of the drainage, peritubal leakage of the seroma, etc. This may result in pain and reduction in mobility of the affected arm.

About this study
Official title: Hemopatch Versus Axillary Drainage After Axillary Lymphadenectomy: Randomized, Controlled, Multicenter Clinical Study
Aspirative drainage continues to be the "gold standard" for the management of this post-surgical complication, even though it can lead to complications such as obstruction of the drainage, peritubal leakage of the seroma, etc. This may result in pain and reduction in mobility of the affected arm.
Based on our positive clinical outcomes and the fact that there is not any published data available in the literature regarding this use of the patch, the investigators propose a multicentric, randomized controlled clinical trial, with the objective of comparing the Hemopatch® with the usual technique used (aspirative drainage) in terms of efficacy and safety.
Hypothesis: Placing a Hemopatch ® instead of an aspirative drainage in women after undergoing axillary lymph node dissection during breast cancer surgery may reduce the appearance of seroma and consequently the need for a puncture, as well as the complications related to aspirative drainage.
Read the detailed description
- Introduction: In the surgical management of breast cancer, a conservative approach is the "gold standard" for the mammary region. For the axillary region, however, this depends on the results of the sentinel lymph node biopsy (SLNB) with axillary lymph node dissection (ALND) continuing to be an indispensable procedure when the disease reaches this level. The complications that arise from this procedure can be divided in two groups: 1) early: seromas and nerve lesions and 2) late: lymphedema, functional disorders in shoulder movement and post-mastectomy pain syndrome. Seromas are the most frequent complications after an ALND. In themselves, they do not carry a high risk of morbidity. However, they delay healing of the surgical wound, increasing the risk of infection and number of ambulatory visits and furthermore, resulting in a deferral in the start of adjuvant therapies such as radio and chemotherapy. Aspirative drainage continues to be the "gold standard" for the management of this post-surgical complication, even though it can lead to complications such as obstruction of the drainage, peritubal leakage of the seroma, etc. This may result in pain and reduction in mobility of the affected arm. Hemopatch® is a hemosthatic sealer made from reabsorbable collagen. It comes in the from of patch, with CE marking that is already being used in the clinical setting in Spain and the rest of Europe. Taking into account the factors that reduce seroma formation after ALND and the characteristics of the patch, its application after surgery could be useful in preventing seroma formation. More specifically, the patch has proven to act as a
- Hemosthatic, improving the first phase of inflammation
- Adhesive, reducing the dead space left after ALND
- Sealer, decreasing the exudate
- Rationale Based on this premise and in the context of a clinical protocol after the introduction of the patch in daily clinical practice, it was used on 28 patients that underwent ALND, obtaining favourable clinical results. This is a multicentric, randomized controlled clinical trial, with the objective of comparing the Hemopatch® with the usual technique used (aspirative drainage) in terms of efficacy and safety.
- Hypothesis Placing a Hemopatch ® instead of an aspirative drainage in women after undergoing ALND during breast cancer surgery may reduce the appearance of seroma and consequently the need for a puncture, as well as the complications related to aspirative drainage.

Compare the costs of both procedures by quantifying the costs of materials and consult time used in both procedures
Measured: through study completion, an average of 1 year

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Aspirative drainage continues to be the "gold standard" for the management of this post-surgical complication, even though it can lead to complications such as obstruction of the drainage, peritubal leakage of the seroma, etc. This may result in pain and reduction in mobility of the affected arm.
Based on our positive clinical outcomes and the fact that there is not any published data available in the literature regarding this use of the patch, the investigators propose a multicentric, randomized controlled clinical trial, with the objective of comparing the Hemopatch® with the usual technique used (aspirative drainage) in terms of efficacy and safety.

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To develop seroma after surgery (time frame: Percentage, through study completion, an average of 2 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04487561, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2023.
