Prospective Feasibility Study Applying the ACOSOG Z0011 Criteria to Chinese Patients

October 14, 2022 updated by: Peng Yuan, Peking University People's Hospital

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.

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

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

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.

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.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

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
overall survival
Time Frame: 5 years
the time from surgery until death from any cause
5 years

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
disease-free survival
Time Frame: 5 years
the time from surgery to death or first documented recurrence of breast cancer
5 years
occurrence of surgical morbidities
