To investigate this regression model by injecting and tracing carbon nanoparticles (CNs) into the fusion node prior to NAC in patients with breast cancer.

Completed

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

Guided by ultrasound, 0.3 mL of CNs suspension was injected in a fusion node prior to NAC in 110 patients with local advanced breast cancer. Patients underwent breast surgery and total axillary lymph node dissection following 2-6 cycles of NAC. The distribution by intercostobrachial nerves (ICBN) of positive nodes, black-stained nodes and lymphovascular invasion was investigated by response to NAC.

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
The spatial distribution of positive nodes in axillary after neoadjuvant chemotherapy based on pectoralis minor location
Time Frame: During the surgery
After neoadjuvant chemotherapy, whether positive nodes remission (transform to negative), from Level III to Level II, and from Level II to Level I. This means that if the nodes at Level I are negative, the nodes at Level II or Level III will be negative; if the nodes at Level II are negative, the nodes at Level III will be negative; if the nodes at Level III are positive, the nodes at Level I and Level II will be positive.
During the surgery

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
The spatial distribution of black-stained in axillary after neoadjuvant chemotherapy based on pectoralis minor location
Time Frame: During the surgery
If the chemotherapy is sensitive, the number of black-stained nodes will increase from Level I, Level II, to Level III. If the chemotherapy is resistance, the number of black-stained nodes will remain the original number or a little increasing locally.
During the surgery
The spatial distribution of positive nodes in axillary after neoadjuvant chemotherapy based on intercostobrachiales nerves (ICBN) location
Time Frame: During the surgery
After neoadjuvant chemotherapy, whether positive nodes remission (transform to negative), from above ICBN to below ICBN. This means that if the nodes below ICBN are negative, the nodes above ICBN will be negative; if the nodes above ICBN are positive, the nodes below ICBN will be positive.
During the surgery
