Trial summary

In patients undergoing breast-conserving surgery and having positive sentinel lymph nodes (SLNs), the ACOSOG Z0011 trial showed equivalent overall survival(OS) and disease-free survival(DFS) outcomes for patients receiving SLN dissection (SLND) alone and those receiving axillary lymph node dissection (ALND).

About this study

Official title: A Prospective Feasibility Study Applying the ACOSOG Z0011 Criteria to Chinese Patients With Early Breast Cancer Undergoing Breast-conserving Surgery

In patients undergoing breast-conserving surgery and having positive sentinel lymph nodes (SLNs), the ACOSOG Z0011 trial showed equivalent overall survival(OS) and disease-free survival(DFS) outcomes for patients receiving SLN dissection (SLND) alone and those receiving axillary lymph node dissection (ALND). We conducted a prospective single-arm study to confirm the applicability of the Z0011 criteria to Chinese patients with breast cancer.

Read the detailed description

The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial demonstrated that in clinically node-negative women with T1 or T2 invasive breast cancer, who underwent breast-conserving surgery (BCT) with whole breast irradiation (WBRT), had excellent local control and survival with SLND alone, even if metastases were found in 1 or 2 SLNs. Recently, the long-term follow-up data of the Z0011 study were reported, which demonstrated that the 10-year OS for patients receiving SLND alone was not inferior to that for those receiving ALND.

This breakthrough result of the Z0011 study led to a change in clinical practice regarding the standard management of axillary lymph nodes in patients with breast cancer.

However, these validation data have been generated in Western populations. As the socio-economic profile, life style and culture of Asian are substantially different from those of Western, and genetic backgrounds vary to some extent, it remains unclear whether results similar to those of the Z0011 study could be achieved in a Chinese breast cancer population. In the present study, we prospectively applied the Z0011 eligibility criteria to Chinese patients with clinically node-negative breast cancer undergoing BCT, with planned RT. The purpose of this study is the clinicopathological relevance of the Z0011 findings for Chinese patients with breast cancer, and to verify the feasibility of using the Z0011 criteria to avoid ALND after positive SLN findings.

This is a prospective single-arm study, enrolled patients meeting Z0011 inclusion criteria and providing consent to receive no additional ALND. Overall survival is the primary end point, disease-free survival and occurrence of surgical morbidities a secondary end point.

What is being measured

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

  1. overall survival

    the time from surgery until death from any cause

    Measured: 5 years

Secondary outcomes (2)
  1. disease-free survival

    the time from surgery to death or first documented recurrence of breast cancer

    Measured: 5 years

  2. occurrence of surgical morbidities

    edema,limited activity or pain on surgical side upper limb

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Sentinel Lymph Node, run by Peking University People's Hospital at 1 site in China.

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 18 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

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?

overall survival (time frame: 5 years). 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 NCT03606616, 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 18 Oct 2022.
