Trial summary

Background Radio Isotopes and Blue dye alone or in combination are the most commonly used tracer agents in sentinel Node Biopsy for early breast cancer. Recent studies have found fluorescence method using Indo Cyanine Green as a promising technology with fewer disadvantages. Read more about this study

About this study

Background Radio Isotopes and Blue dye alone or in combination are the most commonly used tracer agents in sentinel Node Biopsy for early breast cancer. Recent studies have found fluorescence method using Indo Cyanine Green as a promising technology with fewer disadvantages. This study represents the first within a North African setting.

Methods Retrospective analysis of our database that includes patients with clinically node-negative breast cancer scheduled for breast surgery and SN biopsy between 2016 and January 2021. Patients who underwent detection using fluorescence-ICG were included in this study.

Read the detailed description

We performed a retrospective review our data base that includes breast cancer planned for sentinel node biopsy at the F. Hached University teaching hospital(Sousse, Tunisia). Data between April 2016 and January 2021 were reviewed. Only non-pregnant or lacting adult female patients without palpable clinical node and considered suitable for such procedure at multidisciplinary meeting were included. We excluded from our analysis the first ten cases considered as a learning curve Same operator (SH) carried out all the procedures.

Under general anesthesia 5 ml at 2.5mg/ml of Infracyanine ® were injected circumferentially around the areola. Two ml of patent blue-V dye (Laboratoire Guerbet, Aulney-Sous-Bois, France) were injected in combination in the cohort of patients undergoing the procedure after primary chemotherapy. This was followed by a breast massage to facilitate absorption into the lymph vessels, then the surgical lights were turned off and image were obtained under near-infrared light using a first generation Near Infra Red device . Course of subcutaneous lymphatic drainage pathway fluorescence was followed up to where it disappeared to enter to deeper axilla and an incision was performed at that place. Lymphatic duct identification using the NIR camera allowed localization and removal of the sentinel lymph node(s). Further fluorescent imaging was performed to identify potential residual signal in the axilla and such signal-sites were removed. Following ICG assisted-dissection, blue-stained nodes were excised if any. All detected sentinel node were send for frozen section and processed for histological examination. After sentinel node biopsy, conservative surgery or mastectomy were performed according to indication and axillary dissection was performed according to international guidelines.

Statistical analysis Baseline patient's and tumor characteristics, Identification Rate of the sentinel node with Indocyanine green and with dye , when used, were recorded. Data were entered and analyzed in Excel. The continuous variables are presented as mean ± standard deviation and categorical variables are presented as count and percentages unless specified. Informed consents from each patient and IRB approval were obtained

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • sentinel node detectionProcedure or surgery

    Under general anesthesia 5 ml at 2.5mg/ml of Infracyanine ® (Laboratoire SERB; France) were injected circumferentially around the areola. Two ml of patent blue-V dye (Laboratoire Guerbet, Aulney-Sous-Bois, France) were injected in combination in the cohort of patients undergoing the procedure after primary chemotherapy. This was followed by a breast massage to facilitate absorption into the lymph vessels, then the surgical lights were turned off and image were obtained under near-infrared light using a first generation Near Infra Red (NIR) device [K]. Course of subcutaneous lymphatic drainage pathway fluorescence was followed up to where it disappeared to enter to deeper axilla and an incision was performed at that place. Lymphatic duct identification using the NIR camera allowed localization and removal of the sentinel lymph node(s).

What is being measured

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

  1. identification rate

    percentage of cas in whom sentinel node was identified with fluoresence method

    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 Faculty of Medicine, Sousse.

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 10 May 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

identification rate (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 May 2021.
