Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT06085274). This is a study registration, not published results. Lead sponsor: University Health Network, Toronto. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 100 participants (ESTIMATED). Conditions: Breast Cancer. Interventions: PROCEDURE: ICG guided sentinel lymph node biopsy. Primary outcome measures: Non-inferiority of ICG SLNB compared to dual-tracer SLNB in post-neoadjuvant chemotherapy treated breast cancer patients. , From Technetium-99 (Tc-99m) injection to the completion of surgery. Brief summary: This is a prospective, open-label, within-patient clinical trial to determine the accuracy of Indocyanine green (ICG) guided sentinel lymph node biopsy (SLNB) compared to the standard dual-tracer SLNB in breast cancer patients who have had chemotherapy as a first treatment using a non-inferiority design. Patients with operable breast cancer treated with chemotherapy and eligible for SLNB will be included in the study. During surgery, ICG will be injected and used to identify fluorescent sentinel nodes using a hand-held imaging camera; radiotracer and blue dye will also be used as per standard protocols. Intraoperative and clinicopathologic outcomes such as complications, characteristics of nodes, false negative rates and feasibility will be assessed. Patients will be asked to complete standardized patient reported outcome questionnaires (Breast-Q, FACT-B+4, VAS) to define the patient experience with this novel technique.
