About this study

Official title: T1-T2 Breast Cancer: Comparison Between Removal and Preservation of Axillary Lymph Nodes in the Presence of Sentinel Lymph Node Metastases (SINODAR ONE)

Italian Multicentric non inferiority two-arm randomized clinical trial to verify that the experimental treatment (omission of axillary lymph node intervention) in the presence of sentinel lymph node metastases does not lead to a significant worsening in survival or in the risk of locoregional recurrence compared to standard treatment (removal of I-II level of axillary lymph nodes).

Read the detailed description

Detailed Description:

The trial is a non-inferiority trial; patients, depending on intra-operative or post-operative sentinel lymph node assessment, are randomly assigned to one of the two intervention groups:

group 1: removal of I-II level of axillary lymph nodes (standard treatment). Removal of at least 10 lymph nodes is recommended.

group 2: no axillary lymph nodes dissection (experimental treatment). Patients for whom sentinel lymph node cannot be found, will undergo complete dissection of the axillary cavity as required by international guidelines.

After surgery, according to their bio-pathological profile and to the international guidelines criteria, patients will be able to receive:

  • no further treatment
  • complementary radiotherapy
  • adjuvant medical therapy (chemo and / or hormone therapy).

Patients will be checked for at least 5 years in the following ways:

  • six-monthly clinical examination for the first 5 years and yearly thereafter
  • mammography + annual breast ultrasound
  • annual axillary ultrasound in cases not subjected to dissection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall Survival (OS)

    Evaluating whether, in women operated for breast cancer (T1-T2) with sentinel lymph node metastases, axillary lymph node conservation is associated with a clinically relevant prognostic worsening (OS). For all the Outcomes Statistical analysis included Kaplan-Meier Product Limit Estimator and the log-rank test

    Measured: 5 years of follow up after surgery

Secondary outcomes (2)
  1. Regional Disease Free Survival (RDFS)

    Evaluating whether axillary lymph node preservation is associated with a clinically relevant increase of local recurrence rate (ipsilateral axillary and supraclavicular lymph nodes).

    Measured: 5 years of follow up after surgery

  2. Disease-free distance survival (DDFS)

    Evaluating whether axillary lymph node preservation is associated with a clinically relevant increase in distant recurrence rate.

    Measured: 5 years of follow up after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Removal of axillary lymph nodes. and Preservation of axillary lymph nodes in people with Breast Cancer, run by Fondazione Humanitas per la Ricerca.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

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?

Results are not available in the source record.

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?

Overall Survival (OS) (time frame: 5 years of follow up after surgery). 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 NCT05160324, which also lists 1 linked publication.

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 5 Jan 2022.
