Filter by:Determining the prognosis of breast cancer relies significantly on axillary staging by sentinel lymph node biopsy (SLNb). The SLNb is generally performed using radioisotopes, blue dyes, or both to improve the false negative rate. However, a gamma probe with radioisotopes involves ionizing radiation, and blue dye detection relies on visual inspection by an operator. To overcome these limitations, the photoacoustic finder (PAF) was developed as a highly sensitive, non-radioactive detector that uses only blue dye and a photoacoustic signal to detect SLNs. To evaluate the PAF, its performance was compared with the standard SLN detection method for breast cancer patients.
This study aims to compare sentinel lymph nodes biopsy versus comprehensive lymphadenectomy in patients with early stage cervical cancer who underwent radical hysterectomy.
The goal of this study was to assess the feasibility of SLND by superparamagnetic iron oxide nanoparticles (SPIO) in patients with early breast cancer planned for primary systemic therapy (PST) and whether this is affected by the timeframe of SPIO administration. For this, patients with cN0/1 disease planned for PST received radioisotope as per routine on the day of surgery or the day before, and SPIO was injected in an extended timeframe, at any point from the day of surgery to before the induction of PST. The main points to investigate are: 1. If the SPIO detection rate and concordance to the radiosotope are affected by time of SPIO injection 2. If the nodal yield and the accuracy of the procedure are affected
Sentinel lymph node (SLN) status is pivotal for treatment decisions in breast cancer patients. The dual technique with Technetium99m (Tc99) and blue dye (BD) is yet the current routine for SLN detection. However, the same reliability has been presented by superparamagnetic iron oxide nanoparticles (SPIO). The aim of this study was to determine if SLN detection using ultra-low dose SPIO is feasible.
Sentinel lymph node biopsy is mandatory during breast cancer operation for disease staging and treatment. The localization of sentinel lymph node is by the injection of radioisotope and blue dye, which is the gold standard. However the use of radioisotope and blue dye are associated with specific drawbacks. Superparamagnetic iron oxide is a magnetic tracer which is FDA-approved for sentinel lymph node localization. The hypothesis of this study is superparamagnetic iron oxide can replace the conventional dual mapping of radioisotope and blue dye in the detection of sentinel lymph nodes for early breast cancers.
NAUTILUS study is a prospective, multicenter, RCT. Clinically T1,T2, node negative BCS candidates with no evidence of metastases in AUS are 1:1 randomized into no SLNB group and SLNB group. NAUTILUS study aim to establish the minimally invasive treatment of breast cancer by reexamining the necessity of sentinel lymph node biopsy among patients with invasive breast cancer who have tumors under 5cm, are clinically node-negative, and are having breast conserving surgery performed.
