Sentinel Lymph Node Biopsy in Patients With Breast Cancer After Neoadjuvant Therapy

February 16, 2021 updated by: University Hospital Ostrava
The aim of this study is to create clear indications for Sentinel Lymph Node Biopsy (SLNB) or Axillary Dissection (AD) in women with breast carcinoma after neoadjuvant therapy by studying the false negative rate of SLNB.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

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 main object of the study is to evaluate, whether sentinel lymph node biopsy (SLNB) at women with breast cancer after neoadjuvant therapy is a method with a high false-negative rate. Patients will be classified into groups according to histological findings during SLNB, clinical and ultrasonography (USG) findings in the axilla. The aim of this study is to create clear indications for SLNB or axillary dissection (AD). In case of extension of SLNB indications, there will be a decrease in morbidity after surgical therapy when compared to AD, which will mean a profit for the patients.

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.

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
Clear indications for SLNB or axillary dissection
Time Frame: 24 months
Clear indications for SLNB or axillary dissection (AD) in women with breast carcinoma after neoadjuvant therapy using false-negativity rate of SLNB. False-negativity rate of SLNB under 10% is acceptable for avoiding AD.
24 months

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
Morbidity
Time Frame: 24 months
Morbidity after SLNB and AD will be assessed by check-ups provided by clinicians. The result will be the percentage of patients which suffer from some complications after SLNB or AD. Common morbidity rate after AD is 20%, after SLNB 1-2%.
24 months
Changes in the Quality of Life
Time Frame: 24 months
Changes in the Quality of Life will be assessed using the standardised World Health Organisation Quality of Life (WHOQOL) questionnaire.
24 months
Overall Survival
Time Frame: 24 months
The overall survival (in months, years) of the patients will be assessed.
24 months
Disease-free Survival
Time Frame: 24 months
The disease-free survival (in months, years) of the patients will be assessed.
24 months
Progression-free Survival
Time Frame: 24 months
The progression-free survival (in months, years) of the patients will be assessed.
