Sentinel Node Biopsy Vs Observation After Axillary PET (SOAPET)

July 10, 2020 updated by: Zhimin Shao, Fudan University

Sentinel Node Biopsy Vs Observation After Axillary PET Examination

Several researches have proved that avoiding axillary surgery does not worsen the outcome of breast cancer patients with relatively low risk. Based on the routine axillary imaging evaluation (ultrasound and MR etc.) and latest dedicate lymph node PET (LymphPET), axillary nodal burden can be identified before operation.

Therefore this prospective study are designed to evaluate the negative predictive value of LymphPET and to verify whether sentinel lymph node biopsy can be spared in patients with negative preoperative axillary assessment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
stage 1: negative predictive value
Time Frame: 6 months
negative predictive value of LymphPET in breast cancer patients with a negative preoperative axillary assessment
6 months
stage 2: D-DFS(distant disease-free survival)
Time Frame: 5 years
D-DFS of patients with negative preoperative axillary assessment(including LymphPET and other imaging examination) and for whom axillary surgery is spared
5 years
stage 2: LRFS(local-regional free survival)
Time Frame: 5 years
LRFS of patients with negative preoperative axillary assessment(including LymphPET and other imaging examination) and for whom axillary surgery is spared
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
stage 1: false negative rate
Time Frame: 6 months
false negative rate of LymphPET in breast cancer patients with a negative preoperative axillary assessment
6 months
stage 2: DFS(disease-free survival)
Time Frame: 5 years
DFS of patients with negative preoperative axillary assessment(including LymphPET and other imaging examination) and for whom axillary surgery is spared
5 years
stage 2: OS(overall survival)
Time Frame: 5 years
OS of patients with negative preoperative axillary assessment(including LymphPET and other imaging examination) and for whom axillary surgery is spared
5 years
stage 2: adverse events of upper limbs
Time Frame: 5 years
adverse events of patients with negative preoperative axillary assessment(including LymphPET and other imaging examination) and for whom axillary surgery is spared，as assessed by CTCAE v5.0
5 years
stage 2: breast self evaluation
Time Frame: 5 years
breast self evaluation for patients with negative preoperative axillary and for whom axillary surgery is spared, as assessed by BREAST Q© index. The BREAST-Q has a modular, procedure-specific structure with scales that evaluate both satisfaction and quality of life. Psychometric evaluation reveals high reliability, validity and responsiveness to surgical intervention across all scales. Breast Q is composed of aesthetical and emotional modules, and each score ranges from 1 to 4 points (higher values represent a better self evaluation). By comparing the sum of the score in different modules before and after the surgery, Breast Q can help to facilitate a self evaluation for breast cancer patients.
